Treatment of patients with type 2 diabetes with the SGLT2 inhibitor dapagliflozin led to a significant drop in the occurrence of ‘fast decline’ of renal function in more than 15,000 patients enrolled in the drug’s main cardiovascular outcome trial, another example of the potent renal protective effects of agents from this drug class.

Among patients with type 2 diabetes enrolled in the DECLARE-TIMI 58 trial, the incidence of a fast decline in renal function, defined as a drop in estimated glomerular filtration rate (eGFR) of at least 3 mL/min per 1.73 m², was 27% among patients treated with dapagliflozin and 37% in control patients who received placebo, a statistically significant difference for this post-hoc analysis, Itamar Raz, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

This finding, which adds to a long list of other renal function parameters reported to have been improved by treatment with sodium-glucose cotransporter 2 (SGLT2) inhibitors, “emphasizes the value of SGLT2 inhibitors as an important component of both prevention and treatment of chronic kidney disease among patients with type 2 diabetes,” said Dr. Raz, a diabetes researcher and professor of medicine at Hadassah University Hospital in Jerusalem.

The primary, prespecified renal outcomes in DECLARE-TIMI 58 were a cardiorenal composite outcome of sustained decline of at least 40% in eGFR to less than 60 mL/min per 1.73 m², end-stage renal disease (defined as dialysis for at least 90 days, kidney transplantation, or confirmed sustained eGFR of less than 15 mL/min per 1.73 m²), or death from renal or cardiovascular causes; and a second prespecified renal-specific composite outcome that was the same except for excluding death from cardiovascular causes. The results showed that the cardiorenal outcome dropped by a statistically significant 24% with dapagliflozin treatment relative to control patients, and the renal-specific outcome fell by a statistically significant 47% with dapagliflozin relative to control patients (Lancet Diab Endocrinol. 2019 Aug 1;7[8];606-17).

The new findings on the incidence of fast decline in renal function help to further flesh out the scope of renal benefit exerted by SGLT2 inhibitors like dapagliflozin in patients with type 2 diabetes, said experts. Fast decline is a relatively recently devised measure of a high-risk, precipitous loss of renal function that has been defined as a drop of either 3 or 5 mL/min per 1.73 m² per year (Kidney Int. 2017 Jun;91[6]:1300-11); for this analysis Dr. Raz and his associates used the less stringent definition.
 

Finding and treating ‘fast decliners’

The new report from Dr. Raz “confirms the original [renal] findings and looks to expand them to a particularly high risk group: the fast decliners,” commented Robert A. Gabbay, MD, chief science & medical officer of the ADA. “In some ways, the group of patients that we need to find a better treatment for most are those whose GFR declines quickly. We don’t always know who they are until after the fact, and studies have been looking for markers that might prospectively identify them,” he said in an interview.

The new analysis showed that dapagliflozin “was effective in this subgroup of patients. Furthermore, it didn’t matter if they had significant baseline disease or not. Even people with normal kidney function [at baseline] who were still fast decliners fared better with the drug than without it. This suggests that, if it can be confirmed in a prospective study, dapagliflozin might be effective very early in the course of treatment if we can identify who will be the fast decliners.”

Dr. Raz and his associates had the data necessary to calculate the rates of eGFR decline during the full follow-up period for 15,012 of the 17,160 patients enrolled in DECLARE-TIMI 58, and they found that 4,788 (32%) were fast decliners and 10,224 had a slower rate of renal deterioration. The average annual decline in eGFR during the period from 6 months after study entry through 4 years was 6.3 mL/min per 1.73 m² per year (median of 5.1 mL/min per 1.73 m² per year) among the fast decliners, and zero (median of 0.6 mL/min per 1.73 m² per year) among the other patients.
 

Overcoming dapagliflozin’s initial eGFR reduction

The researchers focused on the 6-month to 4-year period of treatment as more representative of the impact of dapagliflozin because the SGLT2 inhibitors have an established pattern of triggering an initial, moderate decline in eGFR over roughly the first 6 months on the drug, which is similar to what happens to patients who start treatment with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker.

“Some patients get as much as a 10% decline in eGFR” when SGLT2 inhibitor treatment starts, but “patients do better over time even with this initial hit,” the same way they do on drugs that act on the renin-angiotensin system, explained Silvio E. Inzucchi, MD, an endocrinologist and professor of medicine at Yale University in New Haven who has extensively studied the SGLT2 inhibitors.

The analyses reported by Dr. Raz showed that the protection against fast decline during the 6-month to 4-year period with dapagliflozin treatment was consistent across a range of patient subgroups regardless of age, duration of their type 2 diabetes, their baseline level of hyperglycemia, and their baseline eGFR. Nearly half the patients enrolled in DECLARE-TIMI 58 had an eGFR at baseline of at least 91 mL/min per 1.73 m² and in this subgroup the incidence of fast decliners was 23% with dapagliflozin and 31% on placebo. Among the 45% of patients who began with an eGFR of 60-90 mL/min per 1.73 m² the fast-decliner incidence was 32% and 43% when on or off dapagliflozin. Among the 7% of patients who entered with an eGFR below 60 mL/min per 1.73 m², the fast-decliner incidence was 25% on dapagliflozin and 36% among controls. All the between-group differences were statistically significant.

The incidence of fast decliners was also lower with dapagliflozin treatment when the analysis included the entire first 4 years on treatment, including the first 6 months when SGLT2s usually spikes a loss of renal function. For the entire 4-year period, fast decline occurred among 34% of patients on dapagliflozin and in 37% of control patients, a statistically significant difference.

The mechanisms behind the consistent renal-protective effects of the SGLT2 inhibitors remain unclear right now, but likely seem related to the “perfect” diuretic action the drugs produce, said Dr. Inzucchi. “They’re not as hugely effective as diuretics, but they’re gentler.” While the SGLT2 inhibitors cause a modest amount of fluid loss ”for some reason they don’t activate the compensatory mechanisms that prevent further reductions in plasma volume,” a property that manifests as little or no change in catecholamines or renin-angiotensin activity, which sets this diuretic action apart from what happens with conventional diuretic drugs, he said in an interview.

In DECLARE-TIMI 58 treatment with dapagliflozin met its primary safety outcome of noninferiority to placebo with respect to major adverse cardiovascular events. The results failed to show statistically significant superiority for one of the primary efficacy endpoints, the rate of major adverse coronary events, but they did show significantly better performance for the second primary efficacy outcome of the rate of cardiovascular death or hospitalization for heart failure, which occurred in 4.9% of patients treated with dapagliflozin and in 5.8% of the control patients during a median follow-up of 4.2 years (N Engl J Med. 2019 Jan 24;380[4]:347-57).

The cardiovascular outcome trial results for a fourth sodium-glucose cotransporter 2 (SGLT2) inhibitor, ertugliflozin, were most notable for their consistency with the four prior, similar trials run on the three other drugs from this class on the U.S. market, canagliflozin, dapagliflozin, and empagliflozin, further solidifying the important role this drug class has recently taken on for patients with type 2 diabetes.

But the ertugliflozin results, which showed statistically significant superiority to placebo for just one endpoint, hospitalization for heart failure, made it unclear whether clinicians will regard ertugliflozin as the top agent from this class to prescribe.

“Our big takeaway is that the findings are consistent with what’s been seen in the other studies” of cardiovascular and renal outcomes in the EMPA-REG OUTCOME study of empagliflozin (N Engl J Med. 2015 Nov 26;373[22]:2117-28 ), the CANVAS (N Engl J Med. 2017 Aug 17;377[7]:644-57) and CREDENCE (N Engl J Med. 2019 June 13;380[24]:2295-306 ) studies of canagliflozin, and the DECLARE-TIMI 58 trial with dapagliflozin (N Engl J Med. 2019 Jan 24;380[4]:347-57), Christopher P. Cannon, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

The cardiovascular outcome trials (CVOTs), mandated in 2008 by Food and Drug Administration guidance for type 2 diabetes drugs that is now in the process of undergoing an update, have had the main goal of proving safety, and the primary endpoint of the new ertugliflozin trial, VERTIS-CV, was noninferiority to placebo when used on top of standard type 2 diabetes medications for the combined endpoint of cardiovascular death, nonfatal MI, or nonfatal stroke.
 

Key findings

Both of the tested dosages of ertugliflozin, 5 mg and 15 mg daily, met this endpoint, with event rates over a median 3.0 years of follow-up that ran very close to the placebo rate, clearly proving noninferiority. But the results showed no suggestion of superiority in a study that randomized 5,499 patients to either of the ertugliflozin regimens and 2,747 to placebo, reported Dr. Cannon, a cardiologist and professor of medicine at Harvard Medical School, Boston.

The primary outcome also showed similar event rates for each component of the composite endpoint, and subgroup analysis showed consistent results from ertugliflozin, compared with placebo, regardless of study-cohort subdivision by demographic, clinical, or treatment factors.

The trial design called for a hierarchical sequence of secondary-outcome superiority analyses, starting with the impact of ertugliflozin on cardiovascular death or heart failure hospitalization, and for this outcome ertugliflozin showed a point estimate of a 12% relative risk reduction, compared with placebo-treated patients, but this difference was not statistically significant. This meant that all subsequent superiority analyses in this trial could only be hypothesis generating and not definitive.

This negated the statistical validity of the only statistically significant treatment difference between ertugliflozin and placebo seen in VERTIS-CV, for the outcome of hospitalization for heart failure, where ertugliflozin treatment cut this outcome by 30%, compared with placebo patients. The rate of cardiovascular death alone, as well as a renal composite endpoint each showed no statistically significant benefit of ertugliflozin, compared with placebo, although the renal endpoint came close, with ertugliflozin reducing the combined rate of renal death, need for dialysis, need for renal transplant, or a doubling of serum creatinine from baseline by 19%, compared with placebo (P = .08).

How results compare with prior CVOTs

In some ways, these results seemed to contrast with outcomes from the CVOTs for the other SGLT2 inhibitors, which all showed at least two statistically significant benefits for major endpoints when compared with placebo.

As summarized in a new meta-analysis of all the CVOTs by Darren K. McGuire, MD, a cardiologist and professor of medicine at the University of Texas, Dallas, both empagliflozin and canagliflozin showed statistically significant superiority compared with placebo for their trial’s primary, combined major cardiovascular adverse event endpoint, but dapagliflozin and ertugliflozin did not. Empagliflozin was the sole SGLT2 inhibitor to show a statistically significant cut in cardiovascular deaths, compared with placebo.

The primary, composite renal efficacy endpoints used in these trials were hardest to compare because they differed from study to study, but unlike ertugliflozin, all the other three drugs in the class showed a statistically significant improvement, compared with placebo, for their respective renal outcomes. On the other hand, the pattern of estimated glomerular filtration rates measured at multiple times during the various trials showed a high level of consistency across the CVOTs.

The greatest consistently among the major endpoints across the trials was for heart failure hospitalization. All four agents showed statistically significant improvements, compared with placebo, and all four had roughly equal magnitudes of effect, a cut in event rates by about one-third.

“The greatest magnitude of benefit is for reductions in heart failure hospitalizations and for renal outcomes,” with the heart failure outcomes the “most consistent” across the studies and the renal outcomes “largely consistent,” concluded Dr. McGuire. All together, the five CVOTs for these four SGLT2 inhibitors involved more than 46,000 patients.

“A lot of data suggest these are all class effects,” that are roughly similar across all four of these SGLT2 inhibitors, commented Mark E. Cooper, MBBS, a professor and head of the department of diabetes at Monash University, Melbourne, and designated discussant for the study.

There was “clear homogeneity” between the VERTIS-CV results for hospitalization for heart failure and the other CVOTs, he noted. “I think there is a difference” in the cardiovascular death outcomes, specifically the sole statistically significant, 38% relative risk reduction with empagliflozin that stood out from the other CVOTs, but this difference is “totally unexplained,” added Dr. Cooper. “To really determine differences you’d need head-to-head studies that are unlikely to happen.”

The results of new SGLT2 inhibitor meta-analysis appeared to also “support contemporary society recommendations to prioritize the use of SGLT2 inhibitors independent of glucose-control considerations in patients with type 2 diabetes with or at high risk for cardiovascular and renal complications,” said Dr. McGuire.

“The guidelines have it right. Now it’s on us to implement these treatments to appropriate patients,” concluded Dr. Cannon.
 

Study details

VERTIS-CV (Cardiovascular Outcomes Following Ertugliflozin Treatment in Type 2 Diabetes Mellitus Participants With Vascular Disease) enrolled and followed patients with type 2 diabetes and established atherosclerotic cardiovascular disease at 531 centers in 34 countries during December 2013–December 2019. Other effects from ertugliflozin recorded during the trial were consistent with prior studies of the drug, which is already FDA approved for glycemic control: Compared with placebo, ertugliflozin treatment reduced hemoglobin A1c by an average of 0.5% after 1 year, cut average body weight by about 2.5 kg after 1 year with additional modest weight loss, during subsequent years on the drug, and reduced systolic blood pressure by about 3 mm Hg after 1 year.

The drug’s safety profile was generally reassuring and consistent with prior studies of this drug and others in the class, with overall no increase in total adverse events or serious adverse events, compared with placebo, and modestly increased rates of urinary tract and mycotic genital infections.

VERTIS-CV was sponsored by Merck and Pfizer, the companies that market ertugliflozin (Steglatro). Dr. Cannon has received research funding and fees from Merck and Pfizer and from several other companies. Dr. McGuire has received honoraria from Merck, has been a consultant to Pfizer, and has had similar relationships with several other companies.

The cardiovascular outcome trial results for a fourth sodium-glucose cotransporter 2 (SGLT2) inhibitor, ertugliflozin, were most notable for their consistency with the four prior, similar trials run on the three other drugs from this class on the U.S. market, canagliflozin, dapagliflozin, and empagliflozin, further solidifying the important role this drug class has recently taken on for patients with type 2 diabetes.

But the ertugliflozin results, which showed statistically significant superiority to placebo for just one endpoint, hospitalization for heart failure, made it unclear whether clinicians will regard ertugliflozin as the top agent from this class to prescribe.

“Our big takeaway is that the findings are consistent with what’s been seen in the other studies” of cardiovascular and renal outcomes in the EMPA-REG OUTCOME study of empagliflozin (N Engl J Med. 2015 Nov 26;373[22]:2117-28 ), the CANVAS (N Engl J Med. 2017 Aug 17;377[7]:644-57) and CREDENCE (N Engl J Med. 2019 June 13;380[24]:2295-306 ) studies of canagliflozin, and the DECLARE-TIMI 58 trial with dapagliflozin (N Engl J Med. 2019 Jan 24;380[4]:347-57), Christopher P. Cannon, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

The cardiovascular outcome trials (CVOTs), mandated in 2008 by Food and Drug Administration guidance for type 2 diabetes drugs that is now in the process of undergoing an update, have had the main goal of proving safety, and the primary endpoint of the new ertugliflozin trial, VERTIS-CV, was noninferiority to placebo when used on top of standard type 2 diabetes medications for the combined endpoint of cardiovascular death, nonfatal MI, or nonfatal stroke.
 

Key findings

Both of the tested dosages of ertugliflozin, 5 mg and 15 mg daily, met this endpoint, with event rates over a median 3.0 years of follow-up that ran very close to the placebo rate, clearly proving noninferiority. But the results showed no suggestion of superiority in a study that randomized 5,499 patients to either of the ertugliflozin regimens and 2,747 to placebo, reported Dr. Cannon, a cardiologist and professor of medicine at Harvard Medical School, Boston.

The primary outcome also showed similar event rates for each component of the composite endpoint, and subgroup analysis showed consistent results from ertugliflozin, compared with placebo, regardless of study-cohort subdivision by demographic, clinical, or treatment factors.

The trial design called for a hierarchical sequence of secondary-outcome superiority analyses, starting with the impact of ertugliflozin on cardiovascular death or heart failure hospitalization, and for this outcome ertugliflozin showed a point estimate of a 12% relative risk reduction, compared with placebo-treated patients, but this difference was not statistically significant. This meant that all subsequent superiority analyses in this trial could only be hypothesis generating and not definitive.

This negated the statistical validity of the only statistically significant treatment difference between ertugliflozin and placebo seen in VERTIS-CV, for the outcome of hospitalization for heart failure, where ertugliflozin treatment cut this outcome by 30%, compared with placebo patients. The rate of cardiovascular death alone, as well as a renal composite endpoint each showed no statistically significant benefit of ertugliflozin, compared with placebo, although the renal endpoint came close, with ertugliflozin reducing the combined rate of renal death, need for dialysis, need for renal transplant, or a doubling of serum creatinine from baseline by 19%, compared with placebo (P = .08).

How results compare with prior CVOTs

In some ways, these results seemed to contrast with outcomes from the CVOTs for the other SGLT2 inhibitors, which all showed at least two statistically significant benefits for major endpoints when compared with placebo.

As summarized in a new meta-analysis of all the CVOTs by Darren K. McGuire, MD, a cardiologist and professor of medicine at the University of Texas, Dallas, both empagliflozin and canagliflozin showed statistically significant superiority compared with placebo for their trial’s primary, combined major cardiovascular adverse event endpoint, but dapagliflozin and ertugliflozin did not. Empagliflozin was the sole SGLT2 inhibitor to show a statistically significant cut in cardiovascular deaths, compared with placebo.

The primary, composite renal efficacy endpoints used in these trials were hardest to compare because they differed from study to study, but unlike ertugliflozin, all the other three drugs in the class showed a statistically significant improvement, compared with placebo, for their respective renal outcomes. On the other hand, the pattern of estimated glomerular filtration rates measured at multiple times during the various trials showed a high level of consistency across the CVOTs.

The greatest consistently among the major endpoints across the trials was for heart failure hospitalization. All four agents showed statistically significant improvements, compared with placebo, and all four had roughly equal magnitudes of effect, a cut in event rates by about one-third.

“The greatest magnitude of benefit is for reductions in heart failure hospitalizations and for renal outcomes,” with the heart failure outcomes the “most consistent” across the studies and the renal outcomes “largely consistent,” concluded Dr. McGuire. All together, the five CVOTs for these four SGLT2 inhibitors involved more than 46,000 patients.

“A lot of data suggest these are all class effects,” that are roughly similar across all four of these SGLT2 inhibitors, commented Mark E. Cooper, MBBS, a professor and head of the department of diabetes at Monash University, Melbourne, and designated discussant for the study.

There was “clear homogeneity” between the VERTIS-CV results for hospitalization for heart failure and the other CVOTs, he noted. “I think there is a difference” in the cardiovascular death outcomes, specifically the sole statistically significant, 38% relative risk reduction with empagliflozin that stood out from the other CVOTs, but this difference is “totally unexplained,” added Dr. Cooper. “To really determine differences you’d need head-to-head studies that are unlikely to happen.”

The results of new SGLT2 inhibitor meta-analysis appeared to also “support contemporary society recommendations to prioritize the use of SGLT2 inhibitors independent of glucose-control considerations in patients with type 2 diabetes with or at high risk for cardiovascular and renal complications,” said Dr. McGuire.

“The guidelines have it right. Now it’s on us to implement these treatments to appropriate patients,” concluded Dr. Cannon.
 

Study details

VERTIS-CV (Cardiovascular Outcomes Following Ertugliflozin Treatment in Type 2 Diabetes Mellitus Participants With Vascular Disease) enrolled and followed patients with type 2 diabetes and established atherosclerotic cardiovascular disease at 531 centers in 34 countries during December 2013–December 2019. Other effects from ertugliflozin recorded during the trial were consistent with prior studies of the drug, which is already FDA approved for glycemic control: Compared with placebo, ertugliflozin treatment reduced hemoglobin A1c by an average of 0.5% after 1 year, cut average body weight by about 2.5 kg after 1 year with additional modest weight loss, during subsequent years on the drug, and reduced systolic blood pressure by about 3 mm Hg after 1 year.

The drug’s safety profile was generally reassuring and consistent with prior studies of this drug and others in the class, with overall no increase in total adverse events or serious adverse events, compared with placebo, and modestly increased rates of urinary tract and mycotic genital infections.

VERTIS-CV was sponsored by Merck and Pfizer, the companies that market ertugliflozin (Steglatro). Dr. Cannon has received research funding and fees from Merck and Pfizer and from several other companies. Dr. McGuire has received honoraria from Merck, has been a consultant to Pfizer, and has had similar relationships with several other companies. Dr. Cooper has been an advisor to and received honoraria from Merck. He has also received honoraria from or been an adviser to AstraZeneca, Boehringer Ingelheim, Lilly, MundiPharma, Novartis, Reata, and Servier, and he has received research funding from Boehringer Ingelheim and Novo Nordisk.

Dapagliflozin treatment of patients with heart failure but without diabetes in the DAPA-HF trial led to a one-third cut in the relative incidence of new-onset diabetes over a median follow-up of 18 months in a prespecified analysis from the multicenter trial that included 2,605 heart failure patients without diabetes at baseline.

The findings represented the first evidence that a drug from dapagliflozin’s class, the sodium-glucose cotransporter 2 (SGLT2) inhibitors, could prevent or slow the onset of type 2 diabetes. It represents “an additional benefit” that dapagliflozin (Farxiga) offers to patients with heart failure with reduced ejection fraction (HFrEF) like those enrolled in the DAPA-HF trial, Silvio E. Inzucchi, MD, said at the virtual annual scientific sessions of the American Diabetes Association. DAPA-HF had previously proved that treatment with this drug significantly reduced the study’s primary endpoint of cardiovascular death or heart failure worsening.

During 18 months of follow-up, 7.1% of patients in the placebo arm developed type 2 diabetes, compared with 4.9% in those who received dapagliflozin, a 2.2% absolute difference and a 32% relative risk reduction that was statistically significant for this prespecified but “exploratory” endpoint, reported Dr. Inzucchi, an endocrinologist and professor of medicine at Yale University, New Haven, Conn.

For this analysis, a hemoglobin A1c level of at least 6.5% measured in two consecutive assessments was the criterion for diagnosing incident diabetes. The 2,605 enrolled patients without diabetes in the DAPA-HF trial represented 55% of the entire trial cohort of 4,744 patients with HFrEF.

The 32% relative risk reduction for incident diabetes was primarily relevant to enrolled patients with prediabetes at entry, who constituted 67% of the enrolled cohort based on the usual definition of prediabetes, an A1c of 5.7%-6.4%.

Among all 157 (6%) of the DAPA-HF patients who developed diabetes during the trial, 150 (96%) occurred in patients with prediabetes by the usual definition; 136 of the incident cases (87%) had prediabetes by a more stringent criterion of an A1c of 6.0%-6.4%.

To put the preventive efficacy of dapagliflozin into more context, Dr. Inzucchi cited the 31% relative protection rate exerted by metformin in the Diabetes Prevention Program study (N Engl J Med. 2002 Feb 7;346[6]:393-403).

The findings showed that “dapagliflozin is the first medication demonstrated to reduce both incident type 2 diabetes and mortality in a single trial,” as well as the first agent from the SGLT2 inhibitor class to show a diabetes prevention effect, Dr. Inzucchi noted. Patients with both heart failure and diabetes are known to have a substantially increased mortality risk, compared with patients with just one of these diseases, and the potent risk posed by the confluence of both was confirmed in the results Dr. Inzucchi reported.

The 157 HFrEF patients in the trial who developed diabetes had a statistically significant 70% increased incidence of all-cause mortality during the trial’s follow-up, compared with similar HFrEF patients who remained free from a diabetes diagnosis, and they also had a significant 77% relative increase in their incidence of cardiovascular death. This analysis failed to show that incident diabetes had a significant impact on hospitalizations for heart failure coupled with cardiovascular death, another endpoint of the trial.

“This is a tremendously important analysis. We recognize that diabetes is an important factor that can forecast heart failure risk, even over relatively short follow-up. A drug that targets both diseases can be quite beneficial,” commented Muthiah Vaduganathan, MD, a cardiologist at Brigham and Women’s Hospital in Boston.

The impact of dapagliflozin on average A1c levels during the DAPA-HF trial was minimal, reducing levels by an average of 0.04% among those who entered with prediabetes and by 0.05% among the other patients. This suggests that the mechanisms by which dapagliflozin reduced incident diabetes was by routes that did not involve simply reducing hyperglycemia, and the observed decrease in incident diabetes was not apparently caused by “masking” of hyperglycemia by dapagliflozin, said Dr. Inzucchi.

One possibility is that dapagliflozin, which also improved quality of life and reduced hospitalizations in the DAPA-HF trial, led to improved function and mobility among patients that had beneficial effects on their insulin sensitivity, Dr. Vaduganathan speculated in an interview.

The new finding of dapagliflozin’s benefit “is great news,” commented Yehuda Handelsman, MD, an endocrinologist and diabetes specialist who is medical director of the Metabolic Institute of America in Tarzana, Calif. “It’s an impressive and important result, and another reason to use dapagliflozin in patients with HFrEF, a group of patients whom you want to prevent from having worse outcomes” by developing diabetes.

The DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) trial enrolled HFrEF patients at 410 centers in 20 countries during February 2017–August 2018. The study’s primary endpoint was the composite incidence of cardiovascular death or worsening heart failure, which occurred in 16.3% of patients randomized to receive dapagliflozin and in 21.2% of control patients on standard care but on placebo instead of the study drug, a statistically significant relative risk reduction of 26% (N Engl J Med. 2019 Nov 21;381[21]:1995-2008). In the 2,605-patient subgroup without type 2 diabetes at baseline the primary endpoint fell by a statistically significant 27% with dapagliflozin treatment, the first time an SGLT2 inhibitor drug was shown effective for reducing this endpoint in patients with HFrEF but without diabetes. DAPA-HF did not enroll any patients with type 1 diabetes.

DAPA-HF was sponsored by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. Inzucchi has been a consultant to AstraZeneca and to Abbott, Boehringer Ingelheim, Merck, Novo Nordisk, Sanofi/Lexicon, and vTv Therapeutics. Dr. Vaduganathan has been an adviser to AstraZeneca and to Amgen, Baxter, Bayer, Boehringer Ingelheim, Cytokinetics, and Relypsa.

The new finding of dapagliflozin’s benefit “is great news,” commented Yehuda Handelsman, MD, an endocrinologist and diabetes specialist who is medical director of the Metabolic Institute of America in Tarzana, Calif. “It’s an impressive and important result, and another reason to use dapagliflozin in patients with HFrEF, a group of patients whom you want to prevent from having worse outcomes” by developing diabetes.

The DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) trial enrolled HFrEF patients at 410 centers in 20 countries during February 2017–August 2018. The study’s primary endpoint was the composite incidence of cardiovascular death or worsening heart failure, which occurred in 16.3% of patients randomized to receive dapagliflozin and in 21.2% of control patients on standard care but on placebo instead of the study drug, a statistically significant relative risk reduction of 26% (N Engl J Med. 2019 Nov 21;381[21]:1995-2008). In the 2,605-patient subgroup without type 2 diabetes at baseline the primary endpoint fell by a statistically significant 27% with dapagliflozin treatment, the first time an SGLT2 inhibitor drug was shown effective for reducing this endpoint in patients with HFrEF but without diabetes. DAPA-HF did not enroll any patients with type 1 diabetes.

DAPA-HF was sponsored by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. Inzucchi has been a consultant to AstraZeneca and to Abbott, Boehringer Ingelheim, Merck, Novo Nordisk, Sanofi/Lexicon, and vTv Therapeutics. Dr. Vaduganathan has been an adviser to AstraZeneca and to Amgen, Baxter, Bayer, Boehringer Ingelheim, Cytokinetics, and Relypsa.

A phone, an app, and the next generation of implanted cardiac device data signaling produced an unprecedented level of data transmission compliance in a single-arm, multicenter, pilot study with 245 patients, adding momentum to the expanding penetration of personal smart devices into cardiac electrophysiology.

During 12-month follow-up, the 245 patients who received either a medically indicated pacemaker or cardiac resynchronization therapy (CRT)–pacemaker equipped with Bluetooth remote transmission capability had successful data transfer to their clinicians for 95% of their scheduled data uploads while using a personal phone or tablet as the link between their heart implant and the Internet. This rate significantly surpassed the transmission-success rates tallied by traditional, bedside transmitters in historical control groups, Khaldoun G. Tarakji, MD, said at the annual scientific sessions of the Heart Rhythm Society, held online because of COVID-19.

A related analysis by Dr. Tarakji and colleagues of 811 patients from real-world practice who received similar implanted cardiac devices with the same remote-transmission capability showed a 93% rate of successful data transfers via smart devices.

In contrast, historical performance showed a 77% success rate in matched patients drawn from a pool of more than 69,000 people in routine care who had received a pacemaker or CRT-pacemaker that automatically transmitted to a bedside monitor. Historical transmission success among matched patients from a pool of more than 128,000 routine-care patients with similar implants who used a wand to interrogate their implants before the attached monitor transmitted their data had a 56% rate of successful transmissions.

Cardiac device signals that flow directly into a patient’s phone or pad and then relay automatically via an app to the clinic “are clearly much easier,” than the methods now used, observed Dr. Tarakji, a cardiac electrophysiologist at the Cleveland Clinic. “It is truly as seamless as possible. Patients don’t really need to do anything,” he said during a press briefing. The key is that most patients tend to keep their smart devices, especially their phones, near them all the time, which minimizes the chance that the implanted cardiac device might try to file a report when the patient is not positioned near the device that’s facilitating transmission. When patients use conventional, bedside transmitters they can forget to bring them on trips, while many fewer fail to take their phone. Another advantage is that the link between a phone and a cardiac implant can be started in the clinic once the patient downloads an app. Bedside units need home setup, and “some patients never even get theirs out of the box,” Dr. Tarakji lamented.

Another feature of handheld device transmissions that run off an app is that the app can display clinical metrics, activity, device performance, and transmission history, as well as educational information. All of these features can enhance patient engagement with their implanted device, their arrhythmia, and their health status. Bedside units often give patients little feedback, and they don’t display clinical data. “The real challenge for clinicians is what data you let patients see. That’s complicated,” Dr. Tarakji said.

“This study was designed to see whether the technology works. The next step is to study how it affects risk-factor modification” or other outcomes. “There are many opportunities” to explore with this new data transmission and processing capability, he concluded.

The BlueSync Field Evaluation study enrolled patients at 20 centers in the United States, France, Italy, and the United Kingdom during 2018, and the 245 patients who received a BlueSync device and were included in the analysis sent at least one of their scheduled data transmissions during their 12 months of follow-up. Participants were eligible if they were willing to use their own smart phone or pad that could interact with their cardiac implant, and included both first-time implant recipients as well as some patients who received replacement units.

Personal device–based data transmission from cardiac implants “will no doubt change the way we manage patients,” commented Nassir F. Marrouche, MD, a cardiac electrophysiologist and professor of medicine at Tulane University in New Orleans, and a designated discussant for the report. “Every implanted cardiac device should be able to connect with a phone, which can improve adoption and adherence,” he said.

But the study has several limitations for interpreting the implications of the findings, starting with its limited size and single-arm design, noted a second discussant, Roderick Tung, MD, director of cardiac electrophysiology at the University of Chicago. Another issue is the generalizability of the findings, which are likely biased by involving only patients who own a smart phone or tablet and may be more likely to transmit their data regardless of the means. And comparing transmission success in a prospective study with rates that occurred during real-world, routine practice could have a Hawthorne effect bias, where people under study behave differently than they do in everyday life. But that effect may be mitigated by confirmatory findings from a real-world group that also used smart-device transmission included in the report. Despite these caveats, it’s valuable to develop new ways of improving data collection from cardiac devices, Dr. Tung said.

The BlueSync Field Evaluation study was sponsored by Medtronic, the company that markets Bluetooth-enabled cardiac devices. Dr. Tarakji has been a consultant to Medtronic, and also to AliveCor, Boston Scientific, and Johnson & Johnson. Dr. Marrouche has been a consultant to Medtronic as well as to Biosense Webster, Biotronik, Cardiac Design, and Preventice, and he has received research funding from Abbott, Biosense Webster, Boston Scientific, and GE Healthcare.

Seropositive rheumatoid arthritis (RA) patients had twice the risk for developing pneumonia, compared with seronegative patients, in a study of more than 4,000 RA patients from a single U.S. medical system.

“Patients with seropositive RA, particularly RF [rheumatoid factor]-positive RA, had increased risk for pneumonia throughout the RA disease course that was not explained by measured confounders, including smoking status, multimorbidity, medications, and [erythrocyte sedimentation rate] level,” Jeffrey A. Sparks, MD, said at the annual European Congress of Rheumatology, held online this year due to COVID-19.

“There has been much interest about the relationship between lung inflammation and the generation of RF and CCP [cyclic citrullinated protein] prior to the onset of RA. We hypothesized that patients with seropositive RA might have subclinical lung injury that could predispose them to pneumonia after clinical RA onset,” Dr. Sparks said in an interview. “Pneumonia is one of the most common serious infections in both patients with RA and the general population, and it causes serious morbidity and mortality.”

The doubled relative risk for pneumonia seen in the findings “translates into a clinically meaningful finding when considering the high rate and the many patients at risk since RA is relatively common,” said Dr. Sparks, a rheumatologist at Brigham and Women’s Hospital in Boston.

“Patients with RF-positive RA who present with symptoms concerning for pneumonia should be evaluated carefully for this and for other possible pulmonary manifestations of RA. Vaccination for pneumonia should be strongly considered for patients with RA who are on disease-modifying antirheumatic drugs, and we hope that our report encourages clinicians and patients” to undertake vaccination, he said.

His study used a database of more than 60,000 patients diagnosed with RA as of November 2013 in the records of a large Boston-area medical system that includes physicians affiliated with Brigham and Women’s Hospital and Massachusetts General Hospital. The researchers applied a validated algorithm for calculating a patient’s probability of having RA, and at the level of 97% probability they narrowed the cohort down to just under 10,000 patients. Additional winnowing because of missing data or a history of pneumonia yielded a study group of 4,110, which included 3,279 (80%) who were seropositive for either or both CCP and RF, and 831 (20%) who were seronegative. During a median follow-up of 7.8 years and total follow-up of more than 32,000 patient-years, the overall pneumonia incidence was 5.8%, with a 2.8% rate among the seronegatives and a 6.6% rate among seropositives. After adjustment for age, sex, glucocorticoid use, disease-modifying antirheumatic drug use, and several other possible confounders, the researchers calculated a 99% relative increased rate of pneumonia among all seropositive patients, compared with the seronegatives.

Further analysis looked at pneumonia incidence rates among patients positive only for CCP antibody, positive only for RF antibody, or both, compared with seronegative patients. This showed that CCP seropositivity had no statistically significant link with incident pneumonia, while RF seropositivity linked with a statistically significant, roughly twofold higher rate. Only 6% of all seropositive patients were positive only for CCP antibody, 59% were positive specifically for RF antibody, and 35% for both.

The data Dr. Sparks presented did not include information on pneumonia type, the timing of the pneumonia, compared with the onset of RA, disease activity, or smoking intensity.

“We anticipated that both RF positive and CCP positive would each be associated with pneumonia, so it was somewhat surprising that we only detected this for RF,” Dr. Sparks said. But he added that, because the number of patients with only CCP positivity was relatively so small, “it is still possible that CCP [antibody] could also increase pneumonia risk.”

The study had no commercial funding. Dr. Sparks had no disclosures.

Roughly half of adolescents and young adults with either type 1 or type 2 diabetes for about a decade had diastolic dysfunction, a direct precursor to heart failure, in a multicenter echocardiography survey of 479 American patients.

Using tissue Doppler echocardiography findings from 258 adolescents and young adults with type 1 diabetes, and 221 with type 2 diabetes, the study found at least one imaging marker of ventricular stiffness – diastolic dysfunction – in 58% of the patients with type 2 diabetes and in 47% of those with type 1 diabetes. The type 1 patients averaged 21 years of age with a median 12 years of diagnosed disease, while the type 2 patients had an average age of 25 years and a median 11 years disease duration.

The analysis also identified several measures that significantly linked with the presence of diastolic dysfunction: older age, female sex, nonwhite race, type 2 diabetes, higher heart rate, higher body mass index, higher systolic blood pressure, and higher hemoglobin A_1c.

“Our data suggest targeting modifiable risk factors” in these patients in an effort to slow the process causing the diastolic dysfunction, Amy S. Shah, MD, said at the virtual annual scientific sessions of the American Diabetes Association. She particularly cited interventions aimed at reducing body mass index, lowering blood pressure, and improving glycemic control, as well as preventing type 2 diabetes in the first place.

Prevention of type 2 diabetes, as well as prevention of diastolic dysfunction development and progression, are key steps because of the substantial clinical consequences of diastolic dysfunction, triggered by stiffening of the left ventricle. Diastolic dysfunction leads to increased left ventricular diastolic pressure, left atrial dysfunction, and ultimately heart failure with preserved ejection fraction, a common diabetes complication that currently has no treatment with proven efficacy, said Dr. Shah, a pediatric endocrinologist and director of the Adolescent Type 2 Diabetes Program at Cincinnati Children’s Hospital Medical Center.

“It’s very concerning that diastolic dysfunction is so prevalent in this age group,” commented Robert A. Gabbay, MD, Chief Science & Medical Officer of the American Diabetes Association. “An important question is whether you can see an improvement by reversing risk factors.” He noted the importance of confirming the finding in additional cohorts as well as running prospective studies looking at the impact of risk factor modification.

Dr. Shah and her associates used data collected at four U.S. centers from patients enrolled in the SEARCH for Diabetes in Youth study who underwent a tissue Doppler examination during 2016-2019, and used three measures derived from the scans to identify diastolic dysfunction:

• The E/A ratio, which compares the early flow wave across the mitral valve (E) with the atrial flow wave (A) that occurs after atrial contraction. Lower values reflect worse pathology.
• The E/e’ ratio, which compares the early flow wave across the mitral valve (E) with the rate of cardiac wall relaxation in early diastole (e’). Higher values reflect worse pathology.
• The e’/a’ ratio, which compares the rate of cardiac wall relaxation in early diastole (e’) with the rate of cardiac wall relaxation in late diastole (a’). Lower values reflect worse pathology.

The most common abnormality involved the e’/a’ measure, which occurred in roughly 38% of the patients with type 2 diabetes and in about 23% of those with type 1 diabetes. Next most common was an abnormally high E/e’ ratio, and fewer than 10% of patients had an abnormally low E/A ratio. Both the E/A and E/e’ values were significantly worse among patients with type 2 diabetes compared with type 1 patients, while no statistically significant difference separated the two subgroups for prevalence of an e’/a’ abnormality after adjustment for body mass index, blood pressure, and HbA_1c values.

Average body mass index among the 221 studied patients with type 2 diabetes was 38 kg/m², 74% were girls or women, and 57% were non-Hispanic black and 24% non-Hispanic white. Mean blood pressure among the patients with type 2 diabetes was 123/80 mm Hg, while it was 110/72 mm Hg among the 258 patients with type 1 diabetes.

Using tissue Doppler echocardiography findings from 258 adolescents and young adults with type 1 diabetes, and 221 with type 2 diabetes, the study found at least one imaging marker of ventricular stiffness – diastolic dysfunction – in 58% of the patients with type 2 diabetes and in 47% of those with type 1 diabetes. The type 1 patients averaged 21 years of age with a median 12 years of diagnosed disease, while the type 2 patients had an average age of 25 years and a median 11 years disease duration.

The analysis also identified several measures that significantly linked with the presence of diastolic dysfunction: older age, female sex, nonwhite race, type 2 diabetes, higher heart rate, higher body mass index, higher systolic blood pressure, and higher hemoglobin A_1c.

“Our data suggest targeting modifiable risk factors” in these patients in an effort to slow the process causing the diastolic dysfunction, Amy S. Shah, MD, said at the virtual annual scientific sessions of the American Diabetes Association. She particularly cited interventions aimed at reducing body mass index, lowering blood pressure, and improving glycemic control, as well as preventing type 2 diabetes in the first place.

Prevention of type 2 diabetes, as well as prevention of diastolic dysfunction development and progression, are key steps because of the substantial clinical consequences of diastolic dysfunction, triggered by stiffening of the left ventricle. Diastolic dysfunction leads to increased left ventricular diastolic pressure, left atrial dysfunction, and ultimately heart failure with preserved ejection fraction, a common diabetes complication that currently has no treatment with proven efficacy, said Dr. Shah, a pediatric endocrinologist and director of the Adolescent Type 2 Diabetes Program at Cincinnati Children’s Hospital Medical Center.

“It’s very concerning that diastolic dysfunction is so prevalent in this age group,” commented Robert A. Gabbay, MD, Chief Science & Medical Officer of the American Diabetes Association. “An important question is whether you can see an improvement by reversing risk factors.” He noted the importance of confirming the finding in additional cohorts as well as running prospective studies looking at the impact of risk factor modification.

Dr. Shah and her associates used data collected at four U.S. centers from patients enrolled in the SEARCH for Diabetes in Youth study who underwent a tissue Doppler examination during 2016-2019, and used three measures derived from the scans to identify diastolic dysfunction:

• The E/A ratio, which compares the early flow wave across the mitral valve (E) with the atrial flow wave (A) that occurs after atrial contraction. Lower values reflect worse pathology.
• The E/e’ ratio, which compares the early flow wave across the mitral valve (E) with the rate of cardiac wall relaxation in early diastole (e’). Higher values reflect worse pathology.
• The e’/a’ ratio, which compares the rate of cardiac wall relaxation in early diastole (e’) with the rate of cardiac wall relaxation in late diastole (a’). Lower values reflect worse pathology.

The most common abnormality involved the e’/a’ measure, which occurred in roughly 38% of the patients with type 2 diabetes and in about 23% of those with type 1 diabetes. Next most common was an abnormally high E/e’ ratio, and fewer than 10% of patients had an abnormally low E/A ratio. Both the E/A and E/e’ values were significantly worse among patients with type 2 diabetes compared with type 1 patients, while no statistically significant difference separated the two subgroups for prevalence of an e’/a’ abnormality after adjustment for body mass index, blood pressure, and HbA_1c values.

Patients with type 2 diabetes treated with the SGLT2 inhibitor empagliflozin during the landmark EMPA-REG OUTCOME trial had a solidly reduced need to either start insulin treatment or intensify existing insulin treatment, compared with those given placebo, in a post-hoc analysis of the study’s findings.

Mitchel L. Zoler/Frontline Medical News

“Empagliflozin markedly and durably delayed the need for insulin initiation, and reduced the need for large dose increases in patients already using insulin,” Muthiah Vaduganathan, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

The patients in the empagliflozin (Jardiance) arm of EMPA-REG OUTCOME had a 9% rate of initiating insulin treatment after 4 years in the study, compared with a 20% rate among patients who received placebo, a statistically significant 60% relative risk reduction. All patients in the trial continued on their background oral glucose-lowering medications.

Among the 48% of study patients who entered the study already using insulin as part of their usual regimen, 18% of those receiving empagliflozin required a significant increase in their insulin dosage (an increase of at least 20% from baseline) after 4 years. But among the control patients, 35% needed this level of insulin-dosage intensification, again a statistically significant difference that computed to a 58% relative reduction in the need for boosting the insulin dosage.

For both of these endpoints, the divergence between the empagliflozin and control arms became apparent within the first 6 months on treatment, and the between-group differences steadily increased during further follow-up. The analyses pooled the patients who received empagliflozin in the trial, which studied two different dosages of the drug.

Results add to the ‘risk and benefit conversation’

“This is one of the first studies to look at this question in a more granular fashion” in patients with type 2 diabetes receiving a drug from the sodium-glucose cotransporter 2 (SGLT2) inhibitor class, said Dr. Vaduganathan, a cardiologist at Brigham and Women’s Hospital in Boston. It provides “compelling” information to include when discussing oral diabetes-drug options with patients, he said in an interview.

Patients newly diagnosed with type 2 diabetes “often think about insulin” and their potential need to eventually start taking it, with the requirements it brings for training, monitoring, and drug delivery, along with the costs for insulin and glucose monitoring. “Patients are very attuned to potentially needing insulin and often ask about it. A reduced need for insulin will be an important part of the risk and benefit conversation” with patients about potential use of an SGLT2 inhibitor, he said.

Dr. Vaduganathan hypothesized that three factors could contribute to the impact of empagliflozin on insulin initiation and dosage level: a direct glycemic-control effect of the drug, the drug’s positive impact on overall well-being and function that could enhance patient movement, and the documented ability of treatment with empagliflozin and other drugs in its class to cut the rate of heart failure hospitalizations. This last feature is potentially relevant because insulin treatment often starts in patients with type 2 diabetes during a hospitalization, he noted.
 

Handelsman: Analysis shows no ‘spectacular effect’

The association of empagliflozin treatment with a reduced need for insulin seen in these data is consistent with expectations for patients with type 2 diabetes who receive an additional oral drug, commented Yehuda Handelsman, MD, an endocrinologist and diabetes specialist who is medical director of The Metabolic Institute of American in Tarzana, Calif. “In large part it has to do with patients on placebo having to get more insulin” because their additional oral-drug options were limited. Dr. Handelsman pointed out that during the period when the EMPA-REG OUTCOME trial ran, from 2010-2015, fewer oral drugs were available than today, and clinicians in the study were encouraged to treat patients to their goal glycemia level according to local guidelines. In addition to a modest but useful glycemic control effect from SGLT2 inhibitors that, on average, cut hemoglobin A_1c levels by about 0.5%, they may also give a small boost to insulin sensitivity that can also defer the need to add or increase insulin. The level of insulin-treatment deference reported in the new analysis was “not a spectacular effect” he said in an interview.

The EMPA-REG OUTCOME (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) study followed 7,020 patients at 590 sites in 42 countries for a median of 3.1 years. The study’s primary endpoint was a composite of death from cardiovascular causes, nonfatal myocardial infarction (excluding silent MI), or nonfatal stroke, and the results showed a statistically significant 14% relative risk reduction with empagliflozin treatment (N Engl J Med. 2015 Nov 26;373[22]:2117-28 ). The results also showed that 12 weeks into the study, before patients could receive any additional drugs, HbA_1c levels averaged 0.54%-0.6% lower among the empagliflozin-treated patients than those in the placebo arm, with smaller between-group differences maintained through the balance of the study. At entry, more than half the enrolled patients were routinely treated with metformin, and close to half were receiving a sulfonyurea agent.

The EMPA-REG OUTCOME results were also notable as showing for the first time that treatment with an SGLT2 inhibitor drug produced a substantial decrease in heart failure hospitalizations, incident heart failure, and progression of renal dysfunction, effects subsequently confirmed and also found for other agents in this drug class.

EMPA-REG OUTCOME was funded in part by Boehringer Ingelheim and Eli Lilly, the companies that market empagliflozin (Jardiance). Dr. Vaduganathan has been an advisor to Boehringer Ingelheim and to Amgen, AstraZeneca, Baxter, Bayer, Cytokinetics, and Relypsa. Dr. Handelsman has been a consultant to several drug companies including Boehringer Ingelheim and Eli Lilly.

Structural entheseal lesions and reduced bone mineral density detected using high-resolution CT imaging of a pair of knuckle joints in patients with psoriasis strongly linked with subsequent development of psoriatic arthritis (PsA) in a single-center study with 114 patients followed for an average of 2.3 years.

“These findings substantiate the concept of mechano-inflammation in the pathogenesis of psoriatic disease,” and suggest that interventions with high efficacy for controlling entheseal inflammation may be a “particularly valuable strategy in interfering with the onset of PsA in patients with psoriatic disease,” David Simon, MD, said at the annual European Congress of Rheumatology, held online this year due to COVID-19.

The study, which is now published in Arthritis & Rheumatology, began with 377 patients with psoriasis who had been referred to the University Hospital in Erlangen, Germany, during 2011-2018, and who tested positive on the German Psoriasis Arthritis Diagnostic questionnaire. The researchers excluded patients with existing signs of PsA, any arthritis or enthesitis or other signs of inflammatory rheumatic disease, and they also excluded patients who had not undergoing a high-resolution peripheral quantitative CT (HR-pQCT) examination of the second and third metacarpal joints of the patient’s nondominant hand, which left 114 patients for their analysis. During a mean follow-up of 28 months, 24 patients (27%) developed PsA. The study patients were an average age of 45 years, and they had been diagnosed with psoriasis for an average of about 16 years.

Dr. Simon and associates used the baseline HR-pQCT scans to make two assessments of each patient: the presence of structural entheseal lesions (SEL) in the two metacarpal joints and the calculated volumetric bone mineral density (vBMD). Their analysis showed that the number and severity of SEL were increased among patients who later developed PsA. In a multivariable model that adjusted for age, sex, body mass index, duration of psoriasis, and arthralgia, patients with any SEL had a fivefold higher rate of developing PsA, compared with patients with no SEL, reported Dr. Simon, a rheumatologist at Erlangen University Hospital.

The analysis of vBMD also showed a strong link between bone density at the entheseal sites of the two studied joints and subsequent PsA development. For every standard deviation increase in vBMD at these sites the subsequent rate of PsA incidence fell by about 67% in an analysis that controlled for the same covariants as well as presence of SEL. The same relationship between higher vBMD and a lower risk for PsA held for both total vBMD measurement and for cortical vBMD, but only at the entheseal site. Levels of vBMD at the intra-articular site of the joints had no statistically significant relationship with subsequent PsA development.

The two metrics also appeared to identify additive risks. Nearly 90% of patients with at least one SEL who also had low vBMD at the entheseal site developed PsA during follow-up, compared with about a 50% rate among patients with at least one SEL but high vBMD.

The imaging method used to run these analyses, HR-pQCT, remains for the time being a “research technique” that “is not generalizable for routine practice,” but further development of this method or of a surrogate measure might make it feasible for future widespread practice, commented Iain McInnes, MD, PhD, president of the European League Against Rheumatism and professor of rheumatology and director of the Institute of Infection, Immunity, and Inflammation at the University of Glasgow.

“We’ve thought for many years that psoriasis and psoriatic arthritis are on a spectrum, and this work is consistent with the idea that some patients with psoriasis develop tissue involvement at entheses and joints,” Dr. McInnes said in an interview. The higher incidence of PsA seen in patients with adverse SEL and vBMD markers was in an “interesting range” that warrants further study. A next step is to run an intervention study in which patients with these adverse markers would receive an intervention randomized against placebo to see if it improved their outcomes, he suggested. Good candidate agents to study in psoriasis patients who have these adverse markers include drugs that inhibit the action of interleukin-17, drugs that target the p19 cytokine subunit of IL-23, and possibly Janus kinase inhibitor drugs.

The analysis of vBMD also showed a strong link between bone density at the entheseal sites of the two studied joints and subsequent PsA development. For every standard deviation increase in vBMD at these sites the subsequent rate of PsA incidence fell by about 67% in an analysis that controlled for the same covariants as well as presence of SEL. The same relationship between higher vBMD and a lower risk for PsA held for both total vBMD measurement and for cortical vBMD, but only at the entheseal site. Levels of vBMD at the intra-articular site of the joints had no statistically significant relationship with subsequent PsA development.

The two metrics also appeared to identify additive risks. Nearly 90% of patients with at least one SEL who also had low vBMD at the entheseal site developed PsA during follow-up, compared with about a 50% rate among patients with at least one SEL but high vBMD.

The imaging method used to run these analyses, HR-pQCT, remains for the time being a “research technique” that “is not generalizable for routine practice,” but further development of this method or of a surrogate measure might make it feasible for future widespread practice, commented Iain McInnes, MD, PhD, president of the European League Against Rheumatism and professor of rheumatology and director of the Institute of Infection, Immunity, and Inflammation at the University of Glasgow.

“We’ve thought for many years that psoriasis and psoriatic arthritis are on a spectrum, and this work is consistent with the idea that some patients with psoriasis develop tissue involvement at entheses and joints,” Dr. McInnes said in an interview. The higher incidence of PsA seen in patients with adverse SEL and vBMD markers was in an “interesting range” that warrants further study. A next step is to run an intervention study in which patients with these adverse markers would receive an intervention randomized against placebo to see if it improved their outcomes, he suggested. Good candidate agents to study in psoriasis patients who have these adverse markers include drugs that inhibit the action of interleukin-17, drugs that target the p19 cytokine subunit of IL-23, and possibly Janus kinase inhibitor drugs.

Structural entheseal lesions and reduced bone mineral density detected using high-resolution CT imaging of a pair of knuckle joints in patients with psoriasis strongly linked with subsequent development of psoriatic arthritis (PsA) in a single-center study with 114 patients followed for an average of 2.3 years.

“These findings substantiate the concept of mechano-inflammation in the pathogenesis of psoriatic disease,” and suggest that interventions with high efficacy for controlling entheseal inflammation may be a “particularly valuable strategy in interfering with the onset of PsA in patients with psoriatic disease,” David Simon, MD, said at the annual European Congress of Rheumatology, held online this year due to COVID-19.

The study, which is now published in Arthritis & Rheumatology, began with 377 patients with psoriasis who had been referred to the University Hospital in Erlangen, Germany, during 2011-2018, and who tested positive on the German Psoriasis Arthritis Diagnostic questionnaire. The researchers excluded patients with existing signs of PsA, any arthritis or enthesitis or other signs of inflammatory rheumatic disease, and they also excluded patients who had not undergoing a high-resolution peripheral quantitative CT (HR-pQCT) examination of the second and third metacarpal joints of the patient’s nondominant hand, which left 114 patients for their analysis. During a mean follow-up of 28 months, 24 patients (27%) developed PsA. The study patients were an average age of 45 years, and they had been diagnosed with psoriasis for an average of about 16 years.

Dr. Simon and associates used the baseline HR-pQCT scans to make two assessments of each patient: the presence of structural entheseal lesions (SEL) in the two metacarpal joints and the calculated volumetric bone mineral density (vBMD). Their analysis showed that the number and severity of SEL were increased among patients who later developed PsA. In a multivariable model that adjusted for age, sex, body mass index, duration of psoriasis, and arthralgia, patients with any SEL had a fivefold higher rate of developing PsA, compared with patients with no SEL, reported Dr. Simon, a rheumatologist at Erlangen University Hospital.

The analysis of vBMD also showed a strong link between bone density at the entheseal sites of the two studied joints and subsequent PsA development. For every standard deviation increase in vBMD at these sites the subsequent rate of PsA incidence fell by about 67% in an analysis that controlled for the same covariants as well as presence of SEL. The same relationship between higher vBMD and a lower risk for PsA held for both total vBMD measurement and for cortical vBMD, but only at the entheseal site. Levels of vBMD at the intra-articular site of the joints had no statistically significant relationship with subsequent PsA development.

The two metrics also appeared to identify additive risks. Nearly 90% of patients with at least one SEL who also had low vBMD at the entheseal site developed PsA during follow-up, compared with about a 50% rate among patients with at least one SEL but high vBMD.

A treat-to-target strategy for managing patients with axial spondyloarthritis failed to meet its primary efficacy endpoint but still showed several suggestive indications of benefit compared with usual care in a multicenter, randomized study with 160 patients.

The treat-to-target management strategy tested aimed to get patients to an Ankylosing Spondylitis Disease Activity Score (ASDAS) of less than 2.1, as recommended for patients with axial spondyloarthritis (axSpA) by an international task force. Also notable about the study was its primary endpoint, at least a 30% improvement in the Assessment of Spondyloarthritis International Society Health Index (ASAS HI), a measure of health-related quality-of-life that the study organizers selected in part because of its distinction from the treatment target.

“For the first time in rheumatology, we targeted inflammation to have an impact on another domain of the disease. Despite not reaching statistical significance, we see a difference between the groups,” Anna Moltó, MD, said at the annual European Congress of Rheumatology, held online this year due to COVID-19.

After 12 months in the study, the 80 axSpA patients assigned to the treat-to-target regimen had a 47% rate of attainment of the primary endpoint, compared with 36% of the 80 patients assigned to usual care, an 11% absolute between-group difference with a P value that came close to but failed to achieve the conventional standard of statistical significance after adjustment for potential confounders (P = .09). Six secondary outcomes showed statistically significant improvements compared with the control patients, including the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the ASAS 20, and ASAS 40. Five additional metrics showed nominal between-group improvements with the treat-to-target strategy that were not statistically significant, including various forms of the ASDAS.

One additional notable finding came from a cost-efficacy analysis run by Dr. Moltó and associates, which showed that the treat-to-target strategy was “dominant” over usual care by producing both better outcomes as well as a lower total cost, compared with control patients, even though twice as many patients on the treat-to-target strategy received a biologic disease-modifying antirheumatic drug (bDMARD) compared with patients in the usual care group. The incremental cost utility ratio for treat-to-target was 19,430 euros (about $22,000) per quality-adjusted life-year gained, putting the strategy into the range of a “cost effective” approach, and the two treatment arms also had comparable safety, said Dr. Moltó, a rheumatologist at Cochin Hospital in Paris.

The 11% increase in treat-to-target patients achieving at least a 30% improvement in their ASAS HI score “is potentially clinically relevant” because the comparator arm in the study received “very active” usual care and was not by any measure a true placebo control group, noted Maxime Dougados, MD, a rheumatologist and professor or medicine at Cochin Hospital and senior investigator for the study. In general, in treatment studies of rheumatologic diseases a 10% or greater absolute increase in the incidence of a beneficial outcome is considered clinically meaningful when compared with an actively-treated control arm, he noted.

“Using the ASAS HI score was very ambitious for the study, and it’s a very relevant outcome,” said Sofia Ramiro, MD, a rheumatologist at Leiden (the Netherlands) University Medical Center who was not associated with the study and chaired the session where Dr. Moltó gave her report. “We have had treat-to-target trials that showed benefit when disease activity was the endpoint.” But when a study “targets treatment to [reducing] disease activity and then uses disease activity as the outcome measure you expect to see an effect, but it is circular reasoning and we are left with challenges in interpreting the results. Now we have a trial that is formally [neutral] but with a different, more ambitious endpoint. All the indications are for benefit from treat-to-target for both the primary endpoint and for all the other endpoints.”

“We were in a difficult situation when choosing the outcome. We didn’t know whether a 30% improvement in the ASAS HI was really relevant, but it seems to be,” said Désirée van der Heijde, MD, a rheumatologist and professor of medicine at Leiden University Medical Center and a collaborator on Dr. Moltó’s study. “I’d choose ASAS HI again as a primary endpoint” for a treat-to-target study in patients with axSpA, she said, but added that a 30% improvement in this score as the response threshold may warrant reconsideration. Both Dr. van der Heijde and Dr. Dougados agreed that at least one additional study with a somewhat similar design is needed to better document and confirm a role for a treat-to-target strategy in axSpA patients.

The Tight Control in Spondyloarthritis (TICOSPA) study ran at 10 French centers and 4 centers each in Belgium and the Netherlands. The study enrolled adults with rheumatologist-diagnosed axSpA with an ASDAS score greater than 2.1 who had not yet received a bDMARD, had not yet maxed out on their dosage of NSAIDs, and had certain baseline immunologic and imaging findings available. The researchers randomized 160 patients to either treat-to-target or usual care management by the center they attended to prevent cross contamination of management strategies. The treat-to-target regimen involved office examinations and consultations every 4 weeks rather than every 3 months with usual care, and also required a predefined management strategy with treatment prompts based on the strategy sent to the treating clinicians via the EMR. The average age of the patients was 38 years, they had been diagnosed with axSpA for an average of just under 4 years, and their mean ASDAS score at entry was 3. During the 12 months of management, 56% of the patients in the treat-to-target arm initiated treatment with a bDMARD, compared with 28% among the controls. Use of NSAIDs was similar between the two study subgroups.

TICOSPA was sponsored by UCB. Dr. Moltó has been a consultant to and received research funding from AbbVie, Bristol-Myers Squibb, Merck, Pfizer, and UCB. Dr. Dougados has had financial relationships with AbbVie, Bristol-Myers Squibb, Janssen, Lilly, Novartis, Merck, Pfizer, and UCB. Dr. van der Heijde has had financial relationships with more than 20 companies including UCB.

Adding a tumor necrosis factor inhibitor to the treatment regimen of patients with psoriatic arthritis who failed to reach minimal disease activity on methotrexate monotherapy after 4 or more weeks had more than triple the rate of minimal disease activity after 16 weeks, compared with patients who had their methotrexate dosage escalated but received no second drug, in a multicenter, randomized study with 245 patients.

After 16 weeks, 42% of 123 patients with psoriatic arthritis (PsA) treated with methotrexate and the tumor necrosis factor (TNF) inhibitor adalimumab achieved minimal disease activity, compared with 13% of 122 patients randomized to receive escalated methotrexate monotherapy to their maximally tolerated dosage or to a maximum of 25 mg/week, Laura C. Coates, MBChB, PhD, reported at the annual European Congress of Rheumatology, held online this year due to COVID-19.

The findings are “supportive of the EULAR recommendations” for managing patients with PsA, said Dr. Coates, a rheumatologist at the University of Oxford (England). The EULAR recommendations call for starting a biologic disease-modifying antirheumatic drug (bDMARD) in patients with PsA and peripheral arthritis and “inadequate response to at least one [conventional synthetic] DMARD,” such as methotrexate (Ann Rheum Dis. 2019 Jun;79[6]:700-12). “A proportion of patients treated with methotrexate do well, but for those struggling on methotrexate, these results support use of a TNF inhibitor. It’s a balance of cost and benefit. If TNF inhibitors were as cheap as methotrexate, I suspect that would be first line more frequently,” Dr. Coates said in an interview. In contrast, the PsA management recommendations from the American College of Rheumatology make treatment with a TNF inhibitor first line, before starting with what these guidelines call an oral small molecule, the same as a conventional synthetic DMARD such as methotrexate (Arthritis Rheumatol. 2019 Jan;71[1]:5-32).

The results seen in the CONTROL study with adalimumab would likely be similar using a different TNF inhibitor or an agent that’s an adalimumab biosimilar, Dr. Coates said. The only patients with PsA and not achieving minimal disease activity on methotrexate monotherapy who should not then receive add-on treatment with a TNF inhibitor are those known to have a safety exclusion for this drug class or patients for whom the incremental cost poses a barrier, she added. In addition, patients with more substantial skin involvement may get greater benefit from a different class of bDMARD, such as a drug that inhibits interleukin-17 or IL-12 and -23 as recommended by the EULAR panel.

“We still get very good results with a TNF inhibitor for psoriasis, but in patients with severe psoriasis there is an argument to use a different drug,” Dr. Coates acknowledged. Skin responses with an IL-17 inhibitor or an IL-12/23 inhibitor “are far better” than with a TNF inhibitor, said Dr. Landewé. He also added the caution that longer-term use of adalimumab “may induce aggravation of PsA in a significant number of patients.”

Adding a tumor necrosis factor inhibitor to the treatment regimen of patients with psoriatic arthritis who failed to reach minimal disease activity on methotrexate monotherapy after 4 or more weeks had more than triple the rate of minimal disease activity after 16 weeks, compared with patients who had their methotrexate dosage escalated but received no second drug, in a multicenter, randomized study with 245 patients.

After 16 weeks, 42% of 123 patients with psoriatic arthritis (PsA) treated with methotrexate and the tumor necrosis factor (TNF) inhibitor adalimumab achieved minimal disease activity, compared with 13% of 122 patients randomized to receive escalated methotrexate monotherapy to their maximally tolerated dosage or to a maximum of 25 mg/week, Laura C. Coates, MBChB, PhD, reported at the annual European Congress of Rheumatology, held online this year due to COVID-19.

The findings are “supportive of the EULAR recommendations” for managing patients with PsA, said Dr. Coates, a rheumatologist at the University of Oxford (England). The EULAR recommendations call for starting a biologic disease-modifying antirheumatic drug (bDMARD) in patients with PsA and peripheral arthritis and “inadequate response to at least one [conventional synthetic] DMARD,” such as methotrexate (Ann Rheum Dis. 2019 Jun;79[6]:700-12). “A proportion of patients treated with methotrexate do well, but for those struggling on methotrexate, these results support use of a TNF inhibitor. It’s a balance of cost and benefit. If TNF inhibitors were as cheap as methotrexate, I suspect that would be first line more frequently,” Dr. Coates said in an interview. In contrast, the PsA management recommendations from the American College of Rheumatology make treatment with a TNF inhibitor first line, before starting with what these guidelines call an oral small molecule, the same as a conventional synthetic DMARD such as methotrexate (Arthritis Rheumatol. 2019 Jan;71[1]:5-32).

The results seen in the CONTROL study with adalimumab would likely be similar using a different TNF inhibitor or an agent that’s an adalimumab biosimilar, Dr. Coates said. The only patients with PsA and not achieving minimal disease activity on methotrexate monotherapy who should not then receive add-on treatment with a TNF inhibitor are those known to have a safety exclusion for this drug class or patients for whom the incremental cost poses a barrier, she added. In addition, patients with more substantial skin involvement may get greater benefit from a different class of bDMARD, such as a drug that inhibits interleukin-17 or IL-12 and -23 as recommended by the EULAR panel.

“We still get very good results with a TNF inhibitor for psoriasis, but in patients with severe psoriasis there is an argument to use a different drug,” Dr. Coates acknowledged. Skin responses with an IL-17 inhibitor or an IL-12/23 inhibitor “are far better” than with a TNF inhibitor, said Dr. Landewé. He also added the caution that longer-term use of adalimumab “may induce aggravation of PsA in a significant number of patients.”
