Patients with metastatic small-cell lung cancer (SCLC) whose disease has progressed after or during treatment with platinum-based chemotherapy now have a new option to try — lurbinectedin (Zepzelca, Jazz Pharma/PharmaMar).

The drug was granted accelerated approval by the US Food and Drug Administration (FDA) based on response data. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial, the FDA notes.

“Small-cell lung cancer is a disease with limited treatment options,” said Bruce Cozadd, chairman and CEO of Jazz Pharmaceuticals. “While patients may initially respond to traditional chemotherapy, they often experience an aggressive recurrence that is historically resistant to treatment.”

“Seeing first-hand the aggressive nature of SCLC and knowing that the large majority of those diagnosed will experience relapse, I am excited to see an effective new treatment demonstrating durable responses,” Jeff Petty, MD, oncology specialist, Wake Forest Baptist Health, Winston-Salem, North Carolina, commented in the company press release. This new drug “is an important and much-needed addition to the treatment landscape for relapsing SCLC,” he added.
 

Approval based on monotherapy trial

The approval is based on a monotherapy clinical trial in 105 patients, which was published in May in Lancet Oncology, with first author José Trigo, MD, from the Hospital Universitario Virgen de la Victoria in Malaga, Spain.  

These were adult patients with both platinum-sensitive and platinum-resistant SCLC who had disease progression after treatment with platinum-based chemotherapy. They were treated at 26 hospitals across six European countries and the US. All patients received lurbinectedin at 3.2 mg/m² by intravenous infusion over 1 hour. Median follow-up was 17.1 months.

Overall response by investigator assessment was seen in 37 (35.2%) of the 105 patients. The response was greater (at 45%) among the patients with platinum-sensitive disease and smaller (22.2%) among those with platinum-resistant disease.

Lurbinectedin demonstrated a median duration of response of 5.3 months as measured by investigator assessment.

In a post-hoc analysis, among the 37 patients who had an initial objective response, the median overall survival was just over 1 year (12.6 months). It was even longer among patients who had platinum-sensitive disease (15.8 months), although it was shorter in patients with resistant disease (10.9 months).

These data are “particularly encouraging,” comment the authors of an accompanying editorial, led by Oscar Arrieta, MD, from the Thoracic Oncology Unit at the Instituto Nacional de Cancerología in Mexico City, Mexico. These response rates “outperform all previous results achieved with topotecan and other less established treatment schemes including cyclophosphamide, doxorubicin, and vincristine, or platinum re-challenge, in this setting.”

“Lurbinectedin represents an innovative approach to conventional anti-cancer drugs, with an elegant mechanism of action based on the inhibition of transcription-dependent replication stress and genome instability of tumor cells,” the editorialists comment. “The drug binds to specific DNA triplets commonly found in transcription sites and triggers cellular apoptosis.”

“At present, the only evidence-based second-line treatment approved for SCLC is topotecan, a topoisomerase 1 inhibitor with moderate activity in patients with sensitive disease, although its effect is much less evident in patients with resistant SCLC,” they continue.

“Overall, the study by Trigo and colleagues presents novel data for a very challenging disease for which few treatment options exist, and the data on response and survival do seem to outperform data from historical controls,” Arrieta and colleagues write.

The editorialists also note that, in this trial, a few patients had received immunotherapy as part of their first-line treatment, and some of these patients (5 of 8 patients, 68%) had “an outstanding rate of durable response to lurbinectedin.” This raises the possibility of a synergistic effect between immunotherapy and lurbinectedin, as the combination seems to enhance immune memory and impair subsequent tumor growth, they add. Further trials will need to explore sequencing of therapy, they suggest.

A large phase 3 study known as ATLANTIS is currently underway.  

The most common grade 3-4 adverse events in the present trial were hematologic abnormalities: anemia (9% of patients), leukopenia (29%), neutropenia (46%), and thrombocytopenia (7%). Serious treatment-related adverse events occurred in 10% of patients, of which neutropenia and febrile neutropenia were the most common (5% each). No treatment-related deaths were reported.

The study was funded by PharmaMar. Trigo and coauthors, and Arrieta and fellow editorialists, all report relationships with pharmaceutical companies, as detailed in the published articles.

The investigational once-weekly basal insulin analog icodec (Novo Nordisk) was comparable in efficacy and safety with once-daily insulin glargine U100, new research suggests.

Julio Rosenstock, MD, of the University of Texas, Dallas, presented the data from the phase 2 pivotal study of icodec on June 14 during the virtual American Diabetes Association 80th Scientific Sessions.

Insulin icodec binds to albumin to create a circulating depot with a 196-hour half-life. A once-weekly injection is designed to cover an individual’s basal insulin requirements for a full week with steady insulin release. Because of its concentrated formulation, its injection volume is equivalent to that of daily glargine U100.

“Many people with type 2 diabetes are reluctant to start on insulin therapy due to the need for daily injections. ... I’m truly excited about the potential of such innovative treatments which could reduce the number of basal insulin injections for my patients with diabetes,” Dr. Rosenstock commented in a Novo Nordisk statement.

During his presentation, he added that the product “has the potential to be a major player in the management of type 2 diabetes if eventually approved.”

Charles M. Alexander, MD, an endocrinologist and managing director of Alexander Associates, Gwynedd Valley, Pa., said that “it’s a phase 2 study. Obviously we need to see the phase 3 data, but it’s very encouraging.”

Dr. Alexander, who was global medical director for diabetes in medical affairs at Merck from 2008 to 2015, observed that “the theory is that you have better adherence to once-weekly, compared to daily [dosing], but when you actually do the studies it’s very difficult to prove that.

“I think the big advantage is that the company can develop a coformulation of [the glucagonlike peptide–1 receptor agonist] semaglutide and icodec in the same pen or vial. ... There is a convenience factor of once weekly over daily.”

In fact, he noted, Novo Nordisk is already in phase 1 trials with that product, called icosema.

“Potential to be transformational”

The phase 2, randomized, double-blind, double-dummy, parallel-group, treat-to-target trial included 247 insulin-naive patients with type 2 diabetes with hemoglobin A1c levels of 7.0%-9.5% despite taking metformin, with about half also taking a dipeptidyl peptidase–4 inhibitor.

They were randomized to weekly insulin icodec plus daily placebo (n = 125) or daily insulin glargine U100 plus weekly placebo (n = 122). All participants took seven injections per week with a vial and syringe plus one injection per week with a pen injector. Doses were titrated up or down to achieve blood glucose levels 70-108 mg/dL, with glargine dose adjustments of 2 or 4 units and icodec units of 14 or 28 units.

Participants were a mean age of 59.6 years, had a diabetes duration of 9.7 years, and 56.3% were men. Baseline A1c was 8.0% overall and fasting blood glucose was 181 mg/dL, and both were similar between the two groups.

The primary endpoint, change in A1c from baseline to week 26, dropped 1.33 percentage points with icodec and 1.15 percentage points with glargine, which was not significantly different (P = .08). Estimated mean A1c levels were 6.7% for icodec and 6.9% for glargine.

The icodec result, Dr. Rosenstock said, “is a very impressive final A1c.”

The proportions of patients achieving A1c <7% by week 26 for icodec versus glargine were 72% versus 68%, and for A1c ≤6.5% were 49% and 39%, respectively. Those differences weren’t statistically significant because of lack of power, Dr. Rosenstock observed.

Fasting plasma glucose levels were nearly identical at 26 weeks, with drops of 58 mg/dL with icodec and 54 mg/dL with glargine (P = .34).

However, there was a significant difference in favor of icodec in the 9-point self-monitoring of blood glucose profile, with a difference in mean change from baseline to week 26 of –7.9 mg/dL (P = .01).

Lower postbreakfast and postlunch glucose peaks at 90 minutes accounted for most of the difference, Dr. Rosenstock noted. 

Total insulin doses during the last 2 weeks of treatment with icodec versus glargine were 229 versus 284 units/week (P = .01); those translate to approximate daily doses of 33 versus 41 units/day, respectively.

Both groups gained a small amount of weight, 1.5 kg with icodec and 1.6 kg with glargine by week 26 (P = .88).

Hypoglycemia was more common with icodec than glargine, including mild (53.6% vs. 37.7%), moderate or clinically significant (16.0% vs. 9.8%), and severe (1 [0.8%] vs. 0 participants). Corresponding event rates were 508.9 versus 210.8 per 100 patient-years (mild hypoglycemia), 52.5 versus 45.6 per 100 patient-years (moderate or clinically significant), and 1.4 versus 0 per 100 patient-years (severe) for icodec versus glargine.

The difference between the two groups in moderate or clinically significant hypoglycemia wasn’t statistically significant (P = .85), and the duration of hypoglycemia wasn’t longer with icodec, compared with glargine, despite its longer duration of action, Dr. Rosenstock emphasized.

Rates of other adverse events were similar between groups.

“Based on the robustness of these data, further evidence on the role of weekly basal insulin icodec will be pursued in a comprehensive phase 3 clinical development program,” Dr. Rosenstock explained. If those data confirm the phase 2 results, “I believe personally that a weekly basal insulin has the potential to be transformational in the management of people with type 2 diabetes needing insulin therapy.”

Dr. Rosenstock has reported receiving research support from, being on advisory boards for, and/or receiving consulting honoraria from Merck, Pfizer, Sanofi, Novo Nordisk, Eli Lilly, GlaxoSmithKline, AstraZeneca, Janssen, Genentech, Oramed, Boehringer Ingelheim, Applied Therapeutics, and Intarcia. Dr. Alexander has reported no relevant financial relationships.

With new daily coronavirus cases rising in at least two dozen states, an explosion of new infections in Arizona is stretching some hospitals and alarming public health experts who link the surge in cases to the state’s lifting of a stay-at-home order a month ago.

Arizona has emerged as one of the country’s newest coronavirus hot spots, with the weekly average of daily cases more than doubling from 2 weeks ago. The total number of people hospitalized is climbing, too.

Over the past week, Arizona has seen an average of more than 1,300 new COVID-19 cases each day.

After the state’s largest hospital system warned about a shortage of ICU beds, Arizona Gov. Doug Ducey, a Republican, pushed back on claims that the health care system could soon be overwhelmed.

“The entire time we’ve been focused on a possible worst-case scenario with surge capacity for hospital beds, ICU beds and ventilators,” Ducey told reporters on Thursday. “Those are not needed or necessary right now.”

While he acknowledged a spike in positive cases, Ducey said a second stay-at-home order was “not under discussion.”

“We put the stay-at-home order there so we could prepare for what we are going through,” he said.

Some states have reopened more slowly with a set of specific benchmarks for different regions, but Arizona took a more aggressive approach.

The state began easing restrictions on businesses in early May and lifted its statewide lockdown order after May 15. Under Arizona’s reopening plan, businesses are advised to follow federal guidance on social distancing.

There is also no requirement for everyone to wear masks in public.

Public health experts agree: The timing of this spike reflects the state’s reopening.

“Perhaps, Arizona will be a warning sign to other areas,” said Katherine Ellingson, an epidemiologist at the University of Arizona. “We never had that consistent downward trend that would signal it’s time to reopen and we have everything in place to do it safely.”

Before Arizona lifted its stay-at-home order, only about 5% of COVID-19 tests registered as positive. On Monday, that number was around 16%.

A slower reopening gives public health agencies time to identify whether cases are rising and then respond with contact tracing and isolating those who are infected.

“With a fast, rapid reopening, we don’t have the time to mobilize those resources,” said Ellingson.

Maricopa County, home to about 60% of the state’s population, has ramped up contact tracing in recent weeks, but it may not have enough capacity if the surge in cases continues.

Dr. Peter Hotez said the spike in Arizona, as well as in parts of Texas such as Houston, Dallas and Austin, is the consequence of removing restrictions too quickly and without a public health system that can keep pace.

“It was just ‘open it up’ and then more or less business as usual, with a little bit of window dressing,” said Hotez, the dean for the National School of Tropical Medicine at Baylor College of Medicine in Houston. “This is not an abstract number of cases. We’re seeing people pile into intensive care units.”

Arizona’s governor has also faced criticism from the mayors of Arizona’s two biggest cities for not putting in place more stringent requirements.

“There is a pandemic and it’s spreading uncontrollably,” said Tucson Mayor Regina Romero, a Democrat. Ducey, she said, “is just putting up his hands and saying ‘the spread is happening and we just have to go about our business.’”

And the governor’s executive order forbids local governments from implementing their own extra measures, which adds to Romero’s frustration. Texas has a similar measure.

“What he did was pretty much tie the hands of mayors and public health officials,” Romero said.

Arizona’s hospital industry has tried to tamp down fears that it’s on the verge of a crisis. Hospitals are still performing elective surgeries.

“It’s very unfortunate because hospitals right now in Arizona are quite busy with elective procedures,” said Saskia Popescu, a Phoenix-based epidemiologist with George Mason University. “You throw in increasing cases of COVID, and that’s going to very much stress your hospital systems.”

Phoenix’s triple-digit summer temperatures actually may fuel the spread of the virus. People forgo outdoor activities and retreat to air-conditioned indoor spaces, where the risk of transmitting the virus goes up significantly.

“My concern is we’re going to see a lot more people in close quarters for prolonged periods of time,” Popescu said.

Since the stay-at-home order was lifted, Popescu and others say they’ve seen people returning to a pre-pandemic mindset, neglecting to wear masks or maintain social distance. Videos of crowded bars have only propelled these fears.

On Thursday, however, Arizona’s top doctor stressed there were also dangers to keeping the state on lockdown, including the mental health effects of loneliness and isolation.

“We know that it’s in the community. We are not going to be able to stop the spread. And so we can’t stop living as well,” said Dr. Cara Christ, health director for the Arizona Department of Health Services.

But Dr. Quinn Snyder, an emergency medicine physician in Mesa, Arizona, said there needs to be more consistent messaging on public health measures like wearing masks.

“Frankly, I just think a wholesale reevaluation of where we’re at is critical right now, but I can tell you that we’re not doing nearly enough,” said Snyder, who has seen the uptick in seriously ill COVID-19 patients firsthand.

“If we continue to head down this path, the virus will press our health care facilities beyond capacity, where we’re going to have to be making tough decisions like who gets a ventilator and who doesn’t.”

With new daily coronavirus cases rising in at least two dozen states, an explosion of new infections in Arizona is stretching some hospitals and alarming public health experts who link the surge in cases to the state’s lifting of a stay-at-home order a month ago.

Arizona has emerged as one of the country’s newest coronavirus hot spots, with the weekly average of daily cases more than doubling from 2 weeks ago. The total number of people hospitalized is climbing, too.

Over the past week, Arizona has seen an average of more than 1,300 new COVID-19 cases each day.

After the state’s largest hospital system warned about a shortage of ICU beds, Arizona Gov. Doug Ducey, a Republican, pushed back on claims that the health care system could soon be overwhelmed.

“The entire time we’ve been focused on a possible worst-case scenario with surge capacity for hospital beds, ICU beds and ventilators,” Ducey told reporters on Thursday. “Those are not needed or necessary right now.”

Tralokinumab, an investigational biologic agent for the treatment of moderate to severe atopic dermatitis (AD), hit all primary and secondary endpoints in three pivotal phase 3 clinical trials presented at the virtual annual meeting of the American Academy of Dermatology.

Tralokinumab is a fully human monoclonal antibody which binds specifically to interleukin-13 and thereby prevents downstream IL-13 signaling. In contrast, dupilumab (Dupixent), at present the only approved biologic agent for AD, blocks both the IL-13 and IL-4 pathways.

Two of the pivotal phase 3 trials presented at AAD 2020 – ECZTRA 1 and ECZTRA 2 – were identically designed, randomized, double-blind, placebo-controlled, 52-week, multinational monotherapy studies including a collective 1,596 adults with moderate to severe AD. In contrast, ECZTRA 3 was a 380-patient, double-blind, randomized, 32-week study of tralokinumab in combination with a topical corticosteroid versus placebo injections plus a topical corticosteroid.

“I would say the take-home point of these trials is they are proof of principle that blocking just IL-13 can be an effective approach. The studies help us understand that IL-13 is an important driver cytokine for the disease,” Eric Simpson, MD, lead clinical investigator for ECZTRA 2, said in an interview.

In all three phase 3 trials, the primary endpoint was achievement of a clinical response as defined by an Investigator Global Assessment score of clear or almost clear skin (IGA 0/1) plus at least a 75% improvement in the Eczema Area and Severity Index score (EASI-75) at week 16. In ECZTRA 1 and 2, this was accomplished in 16% and 22% of patients on 300 mg of tralokinumab administered subcutaneously every 2 weeks, compared with 7% and 11% of placebo-treated controls.

Patients with a clinical response at week 16 were then rerandomized to tralokinumab either every other week or every 4 weeks or to placebo for an additional 36 weeks. At 52 weeks, 51% and 59% of patients in ECZTRA 1 and 2, respectively, who had a clinical response at week 16 maintained an IGA 0/1 response while on tralokinumab every 2 weeks, as did 39% and 45% of those switched to treatment every 4 weeks. Similarly, 60% and 56% of clinical responders at week 16 maintained an EASI-75 response at week 52 with tralokinumab every 2 weeks, as did 49% and 51% of those rerandomized to treatment every 4 weeks.

The safety profile of tralokinumab in the two monotherapy trials was comparable with placebo.

In the ECZTRA studies, tralokinumab achieved significant improvement at week 16 in secondary endpoints including itch, health-related quality of life, and severity and extent of skin lesions.

How does tralokinumab, with its narrower focus targeting a single cytokine, stack up against dupilumab, the dual IL-13/IL-4 inhibitor that’s transformed the treatment of patients with moderate or severe AD?

Dr. Simpson, who was also principal investigator in a pivotal phase 3 trial for dupilumab, emphasized that no firm conclusions can be drawn because there have been no head-to-head comparative trials and the tralokinumab and dupilumab trials had different patient populations, geographic locations, and washout periods. With those caveats, however, he commented that, “just on the surface, numerically, for the monotherapy studies, dupilumab hit some higher targets than tralokinumab in terms of the percentage of patients clear or almost clear.”

In terms of safety, it appears that the risk of conjunctivitis may be lower with tralokinumab than dupilumab, with rates of 7% and 3% through 52 weeks in ECZTRA 1 and 2, respectively, versus 2% with placebo, although again this is “a caveated conclusion,” said Dr. Simpson, professor of dermatology at Oregon Health and Science University, Portland.

Tralokinumab combination therapy in ECZTRA 3

At 16 weeks, 39% of patients treated with tralokinumab plus topical corticosteroids had an IGA of 0/1 and 56% had an EASI-75 response, compared with 26% and 36% of patients on topical corticosteroids plus biweekly placebo injections. More than 90% of patients with a good clinical response at week 16 maintained that response at week 32 while on tralokinumab biweekly plus topical steroids. Among good responders at week 16 who were rerandomized to 300 mg of tralokinumab every 4 weeks plus topical steroids, 78% still had an IGA of 0/1 at week 32, and 91% had an EASI-75, reported Jonathan I. Silverberg, MD, PhD, director of clinical research and contact dermatitis at George Washington University, Washington.

A randomized, placebo-controlled combination therapy study such as this provides information that’s especially useful in clinical practice, Dr. Simpson observed.

“When I’m talking to patients about any biologics or oral therapies, I usually quote the figures from the combination therapy studies because the vast majority of our patients are using topical therapy in addition to systemics,” he said in the interview.

Asked how he envisions tralokinumab’s role in clinical practice, should the drug receive regulatory approval, Dr. Simpson said that he welcomes the prospect of having an additional treatment option to discuss with patients. Tralokinumab could be considered either as first-line therapy in patients who are failing on topical therapy or for patients who don’t respond adequately to or experience limiting side effects on dupilumab.

“There isn’t any established, published treatment algorithm in atopic dermatitis, probably for good reason, since we don’t have data to tell us you should start here and then move there. Those are long, difficult studies to perform,” Dr. Simpson said.

LEO Pharma has announced that it has applied for marketing approval for tralokinumab to the European Medicines Agency and plans to do so with the Food and Drug Administration by year’s end.

Dr. Simpson reported receiving research grants from and serving as a consultant to LEO Pharma, sponsor of the ECZTRA trials. He has similar financial relationships with close to a dozen other pharmaceutical companies.

A proactive long-term strategy of maintenance therapy involving twice-weekly application of combined calcipotriene and betamethasone dipropionate spray foam was safe and effective in patients with moderate plaque psoriasis in the international, randomized PSO-LONG clinical trial, Mark Lebwohl, MD, reported at the virtual annual meeting of the American Academy of Dermatology.

The median time to first relapse – the primary study endpoint – was 56 days in patients randomized to the twice-weekly fixed-dose combination calcipotriene 0.005% and betamethasone dipropionate 0.064% foam (Enstilar), a significantly better outcome than the median 30 days for controls assigned to foam vehicle. Moreover, it took 169 days for 75% of patients on the combination foam to experience their first relapse: three times longer than in controls, added Dr. Lebwohl, principal investigator for PSO-LONG and professor and chair of the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York.

The positive results “could have been predicted,” he said in an interview. “But what really distinguishes this study from others is that no one before has ever done a placebo-controlled, double-blind trial with a topical steroid that lasted a year. This is a first, and we’ve shown that if you limit treatment to twice a week you get dramatic improvements in efficacy at no cost in terms of safety.”

The combination spray foam is approved by the Food and Drug Administration as once-daily therapy in psoriasis patients aged 12 years and older, but only for up to 4 weeks because of safety concerns regarding longer use of the potent topical steroid. However, psoriasis is a chronic disease. The PSO-LONG trial was designed to study the impact of a for-now still-investigational long-term maintenance treatment strategy.

The open-label run-in period of the study included 640 adults with plaque psoriasis, 82% of whom had moderate disease at baseline as rated by Physician Global Assessment (PGA). Participants applied the combination foam once daily for 4 weeks. At that point, 80% of them had achieved a PGA rating of clear or almost clear with at least a two-grade improvement from baseline; these 521 responders were then randomized to 52 weeks of double-blind treatment with the combination foam or vehicle foam. Anyone who relapsed went on 4 weeks of once-daily active treatment with the combination foam, then returned to their original treatment arm.

The risk of a first relapse during the course of 1 year was 43% lower with the combination foam than in controls. The relapse rate over the year was 46% lower. Patients in the active treatment arm spent an average of 256.5 days in remission during the year, compared with 222 days in controls.

“That’s more than 1 month more time in remission during the year with active treatment. And remember, if patients flared, they went on daily therapy for a month,” the dermatologist noted.

The rate of treatment-related adverse events was similar in the two groups at 2.8 events per 100 patient-years in the combination foam arm and 4.5 per 100 patient-years in controls. The twice-weekly active treatment group had no increase in stretch marks, telangiectasias, skin atrophy, serum calcium, or abnormalities of the hypothalamic-pituitary-adrenal axis.

Although the combination foam is approved for daily use for a maximum of 1 month in adolescents and adults, PSO-LONG was restricted to adults.

“I think that what will happen in the marketplace is that the data obtained from this adult study will likely be applied to younger patients,” Dr. Lebwohl predicted.

He reported receiving an institutional research grant to conduct the trial from LEO Pharma, the study sponsor, as well as serving as a consultant to and researcher for the company.

For diabetes patients with no cardiovascular symptoms despite certain risk factors, incorporating coronary calcium scoring into a silent myocardial ischemia screening algorithm may be an effective and cost-conscious strategy that avoids missed coronary stenoses suitable for revascularization, results of a recent study suggest.

Zero patients in need of revascularization were missed in a risk stratification model in which screening for silent myocardial ischemia (SMI) was done only for patients with peripheral artery disease, severe nephropathy, or a high coronary artery calcium (CAC) score, according to investigator Paul Valensi, MD.

In practical terms, that means stress myocardial scintigraphy to detect SMI could be reserved for patients with evidence of target organ damage or a CAC score of 100 or higher, according to Dr. Valensi, head of the department of endocrinology, diabetology, and nutrition at Jean Verdier Hospital in Bondy, France.

“The strategy appears to be a good compromise, and the most cost effective strategy,” Dr. Valensi said in a presentation of the results at the virtual annual scientific sessions of the American Diabetes Association.
 

Utility of CAC scoring in diabetes

This algorithm proposed by Dr. Valenti and colleagues is a “reasonable” approach to guide risk stratification in asymptomatic diabetes patients, said Matthew J. Budoff, MD, professor of medicine and director of cardiac CT at Harbor-UCLA Medical Center in Torrance, Calif.

“Calcium scoring could certainly help you identify those patients (at increased risk) as a first-line test, because if their calcium score is zero, their chance of having obstructive disease is probably either zero or very close to zero,” Dr. Budoff said in an interview.

Using CAC scores to assess cardiovascular risk in asymptomatic adults with diabetes was supported by 2010 guidelines from the American College of Cardiology and the American Heart Association, Dr. Budoff said, while 2019 guidelines from the European Society of Cardiology (ESC) describe CAC score combined with CT as a potential risk modifier in the evaluation of certain asymptomatic patients with diabetes.

“We are starting to see that we might be able to understand diabetes better and the cardiovascular implications by understanding how much plaque (patients) have at the time that we see them,” Dr. Budoff said in a presentation on use of CAC scans he gave earlier at the virtual ADA meeting.

In the interview, Dr. Budoff also noted that CAC scores may be particularly useful for guiding use of statins, PCSK9 (proprotein convertase subtilisin kexin 9) inhibitors, or other treatments in patients with diabetes: “There are a lot of therapies that we can apply, if we knew somebody was at higher risk, that would potentially help them avoid a heart attack, stroke, or cardiovascular death,” he said.
 

CAC scoring and coronary artery stenoses

Although about 20% of patients with type 2 diabetes have SMI, screening for it is “debated,” according to Dr. Valensi.

The recent ESC guidelines state that while routine screening for coronary artery disease in asymptomatic diabetics is not recommended, stress testing or coronary angiography “may be indicated” in asymptomatic diabetics in the very-high cardiovascular risk category.

That position is based on a lack of benefit seen with a broad screening strategy, the guidelines say, possibly due in part to low event rates in randomized controlled trials that have studied the approach.

Using CAC scoring could change the equation by helping to identify a greater proportion of type 2 diabetics with SMI, according to Dr. Valensi.

“The role of the CAC score in the strategy of detection of SMI needs to be defined, and this role may depend on the a priori cardiovascular risk,” he said.

Dr. Valensi and colleagues accordingly tested several different approaches to selecting asymptomatic diabetic patients for SMI screening to see how they would perform in finding patients with coronary stenoses eligible for revascularization.

Their study included 416 diabetes patients with diabetes at very high cardiovascular risk but with no cardiac history or symptoms. A total of 40 patients (9.6%) had SMI, including 15 patients in which coronary stenoses were found; of those, 11 (73.5%) underwent a revascularization procedure.

They found that, by performing myocardial scintigraphy only in those patients with peripheral artery disease or severe nephropathy, they would have missed 6 patients with coronary stenosis suitable for revascularization among the 275 patients who did not meet those target organ damage criteria.

By contrast, zero patients would have been missed by performing myocardial scintigraphy in patients who either met those target organ damage criteria, or who had an elevated CAC score.

“We suggest screening for SMI, using stress myocardial CT scanning and coronary stenosis screening, only the patients with peripheral artery disease or severe nephropathy or with a high CAC score over 100 Agatston units,” said Dr. Valensi.

Dr. Valensi reported disclosures related to Merck Sharp Dohme, Novo Nordisk, Pierre Fabre, Eli Lilly, Bristol-Myers Squibb, AstraZeneca, Daiichi-Sankyo, and others. Coauthors provided no disclosures related to the research. Dr. Budoff reported that he has served as a paid consultant to GE.

Key clinical point: Depressogenic excess eating and weight gain are common in patients with major depressive disorder (MDD) and linked with peripheral dopamine levels.

Major finding: The Yale Food Addiction Scale (YFAS) criteria were met by 29% of patients with MDD vs. 3% of control group individuals. Patients with MDD who met the YFAS criteria showed a significantly higher weight (P = .003), body mass index (P = .001), and waist circumference (P less than .001) than those with MDD not meeting YFAS criteria and control individuals. A positive correlation was observed between plasma dopamine levels and disordered eating behaviors in women.

Study details: The study evaluated patients with MDD (n = 80) and control individuals (n = 60) aged 18-63 years.

Disclosures: No study sponsor was identified. The authors declared no conflicts of interest.

Most disability accumulation in relapsing multiple sclerosis (MS) is not associated with overt relapses, challenging the current clinical distinction of relapsing and progressive forms of the disease, a new analysis shows. “We have to abandon the distinction between relapsing and progressive MS being different populations,” said lead author Ludwig Kappos, MD, University of Basel (Switzerland). “The disease appears to be more of a continuum of disability progression, which is sometimes also accompanied by relapses.”

The analysis was published online June 8 in JAMA Neurology.
 

Assessing disability progression

Noting that there are mounting data to suggest patients with relapsing MS frequently experience worsening disability over time – even when relapse activity appears well controlled – the researchers aimed to investigate the relative contributions of progression independent of relapse activity and relapse-associated worsening to overall accumulating disability in patients with relapsing multiple sclerosis. To do this, they analyzed data from two identical randomized clinical trials (OPERA I and OPERA II) conducted between 2011 and 2015, which compared treatment with the new B-cell–depleting therapy ocrelizumab with interferon beta-1a in 1,656 patients with relapsing MS.

Confirmed disability accumulation was defined by an increase in 1 or more of 3 measures (Expanded Disability Status Scale, timed 25-ft walk, or 9-hole peg test), confirmed after 3 or 6 months, and was classified as being related to a clinical relapse or occurring in the absence of a relapse.

Results showed that after 96 weeks (1.8 years) of treatment, 12-week composite confirmed disability accumulation had occurred in 29.6% of patients receiving interferon beta-1a and 21.1% of those given ocrelizumab; 24-week composite confirmed disability accumulation occurred in 22.7% of interferon beta-1a patients and 16.2% of the ocrelizumab group.

In both treatment groups, the vast majority of events contributing to disability accumulation occurred independently of relapse activity. In the interferon group, 78% of events contributing to 12-week confirmed disability accumulation and 80.6% of events contributing to 24-week confirmed disability accumulation occurred in the absence of clinical relapses, with the corresponding figures in the ocrelizumab group being 88.0% (12 weeks) and 89.1% (24 weeks).

Only a minority of patients (about 17% in both groups) had confirmed disability accumulation accompanied by clinical relapses. Very few patients with confirmed disability accumulation (4% to 5%) experienced disability worsening both associated and independent of relapses. Ocrelizumab was associated with a reduced risk of both relapse-associated and relapse-independent confirmed disability accumulation, compared with interferon beta-1a.

“We found that there was progression of disability in both groups, and the really astonishing finding was that although all patients were classified as having relapsing remitting MS, actually most of the disability progression occurred without preceding relapses,” Dr. Kappos commented. He noted that there have been two previous observational studies that have shown a high rate of disability progressions without temporal association to relapses in relapsing remitting patients, but this is the first time that this progression of disability independent of relapses has been shown in the controlled setting of two prospective, randomized clinical trials over a 2-year period.

“While we expected to see some disability progression independent of relapses, we were surprised to see that the disability progression occurring in both studies was almost exclusively happening without temporal relation to relapses. That was certainly an unexpected finding,” Dr. Kappos said. “These observations make it difficult to keep the current definitions of ‘relapsing remitting’ and ‘secondary progressive’ MS, [ones] that suggest a clear-cut distinction marked by the presence or absence of relapses. This can no longer be justified,” he stressed.

“We are not saying that relapses do not contribute to disability progression. There are a lot of data to support the fact that they do. But I think what we might be seeing is that the drug therapy is quite effective in reducing disability due to relapses but only partially effective in reducing progression independent of relapses,” Dr. Kappos explained.

Although there have been many advances in reducing relapses with drug therapy, focus now needs to shift to the other more continuous process of disability progression independent of relapses, Dr. Kappos said. “There is still a lot of room for improvement here.”

“If continuous progression independent of relapses is already present in the early phases of MS, it is reasonable to study the effects of intervention on steady progression already in this early phase,” he noted. “This might help to capture patients at earlier stages who better respond to treatment aimed at halting progression.”

Dr. Kappos also called for more subtle measurements of disability than the EDSS alone, including measures such as the 9-hole peg test and the 25-ft walk as they did in this analysis. But other measures could also be added that would characterize continuous disease activity and progression, such as laboratory values (e.g., neurofilament light chain) and advanced, more tissue-specific quantitative MRI techniques and digital biomarkers to detect subtle changes in neurologic function.
 

An artificial distinction?

Commenting on the study, Jeffrey Cohen, MD, director of the experimental therapeutics program at the Mellen Center for Multiple Sclerosis Treatment and Research, Cleveland Clinic, said he too sees very little distinction between relapsing remitting and progressive forms of the disease.

“This study confirms what has been suspected for quite a few years –that if one looks sufficiently and carefully, there is gradual worsening of some aspects of the disease in many patients from the earliest stages,” Dr. Cohen said. “Conversely, some patients with progressive MS have superimposed relapses or MRI lesion activity.

“Thus, the distinction between relapsing-remitting and progressive MS subtypes appears artificial,” he concluded.

This study was sponsored by F. Hoffmann–La Roche. Dr. Kappos has received research support from the company.
