Patients whose asthma remains uncontrolled despite treatment may benefit from a new monoclonal antibody that targets an inflammatory cytokine known to be promoted in asthmatic airways, according to data presented at the annual congress of the European Respiratory Society.

The investigators found that exacerbation rates were significantly lower for all three doses of tezepelumab, compared with placebo, with an overall 34% reduction in the risk of exacerbation with tezepelumab (N Engl J Med. 2017;377:936-46).

At 70 mg every 4 weeks, exacerbation rates were 61% lower than in the placebo group; at 210 mg every 4 weeks, they were 71% lower; and at 280 mg every 2 weeks, they were 66% lower (P was less than 001 in comparisons between each group and the placebo).

The overall annualized exacerbation rates by week 52 were 0.26 for the 70-mg group, 0.19 for the 210-mg group, and 0.22 for the 280-mg group, compared with 0.67 in the placebo group, regardless of a patient’s baseline eosinophil count. Patients treated with tezepelumab had a longer time to first asthma exacerbation. They also experienced a significantly higher change from baseline in their prebronchodilator forced expiratory volume in 1 second at week 52, when compared with patients on the placebo.

“The observed improvements in disease control in patients who received tezepelumab highlight the potential pathogenic role of TSLP across different asthma phenotypes,” reported Jonathan Corren, MD, of the University of California, Los Angeles, and his coauthors. “... Although TSLP is central to the regulation of type 2 immunity, many cell types that are activated by or respond to TSLP, such as mast cells, basophils, natural killer T cells, innate lymphoid cells, and neutrophils, may play a role in inflammation in asthma beyond type 2 inflammation.”

The incidences of adverse events and serious adverse events were similar across all groups in the study. Three serious adverse events – pneumonia and stroke in the same patient and one case of Guillain-Barré syndrome – in patients taking tezepelumab, were deemed to be related to the treatment.

The study was supported by tezepelumab manufacturers MedImmune (a member of the AstraZeneca group) and Amgen. Six of the seven authors are employees of MedImmune or Amgen. One author declared support and honoraria from several pharmaceutical companies, one declared a related patent, and five also had stock options in either MedImmune or Amgen.

Body

 

Tezepelumab is the first biologic that has a substantial positive effect on two important markers of the inflammation of asthma – namely, blood eosinophil counts and the fraction of exhaled nitric oxide. It appears to be the broadest and most promising biologic for the treatment of persistent uncontrolled asthma to date.

The observation that tezepelumab reduces the level of both inflammatory markers shows that it hits a more upstream target and that it blocks at least two relevant inflammatory pathways in asthma. This is likely to be clinically relevant, since simultaneously increased exhaled nitric oxide levels and blood eosinophil counts are related to increased morbidity due to asthma.

These comments were taken from an accompanying editorial (N Engl J Med. 2017;377:989-91). Dr. Bel declared consultancies and grants from pharmaceutical companies including AstraZeneca.

Parents of very preterm and VLBW infants have resilient quality of life decades later

A prospective cohort study of parents whose children were born very preterm (VP) or very low birth weight (VLBW) showed that their quality of life once their children reached adulthood was comparable to that of parents of term children. What did predict a poorer quality of life for these parents was whether their children had mental health problems or worse peer relationships in childhood.

AndyL/iStockphoto
The researchers examined participants in the Bavarian Longitudinal Study, made up of parents and caretakers and their children, who were born in Germany between January 1985 and March 1986 and were either VP (less than 32 weeks’ gestation), VLBW (less than 1,500 g), or term. After seven assessments over the ensuing years, 219 VP and VLBW parents and 250 term parents filled out a quality of life and life satisfaction questionnaire when their child was, on average, aged 27.3 years old.

The questionnaire used was the World Health Organization Quality of Life instrument, Short Edition, which assesses physical health, psychological health, social relationships, and environment in 26 items. Parents also answered the five-item Satisfaction with Life Scale.

“The overall Quality of Life factor score of parents of VP and VLBW and term offspring was not different (VP and VLBW: mean standardized factor score −0.02; 95% confidence interval, −0.13 to 0.08; term controls: mean standardized factor score 0.02; 95% CI, −0.07 to 0.12; P greater than .05),” wrote Dieter Wolke, PhD, of the University of Warwick (England) and his coauthors.

VP and VLBW, disabilities, poorer academic achievement, and poorer parent-child relationships did not predict a lower quality of life for the parents. However, “in offspring, better mental health and peer relationships in childhood (independently of whether they were born VP or VLBW or term) still predicted parents’ quality of life more than a decade later,” they said.

Thus, taking measures to improve children’s mental health and peer relationships likely would aid both the children and their parents, they observed.

One thing that the authors do not remark on is that a significant number of the VP and VLBW infants in the Bavarian study’s initial sample died in the hospital (172 of 682; 25%), with another 12 deaths between the infants’ discharge and adulthood; the cohort study’s focus, therefore, is limited to the quality of life of parents whose children are still alive. Some other eligible parents dropped out, although the authors noted that they tried to control for factors differing between the dropouts and the participants.

Adding T-vec might help surmount PD-1 resistance in melanoma

Article Type

Mon, 01/14/2019 - 10:08

 

Almost two-thirds of patients with advanced melanoma responded to combination therapy with pembrolizumab and talimogene laherparepvec (T-vec) in a small phase 1b trial, investigators reported.

The orange object is a tumor, circles with symbols represent CD8 cells, the light green form (top center) is pembrolizumab, and the green circles with red centers represent T-VEC cells.
Anti-programmed death-1 (PD-1) antibodies are becoming standard for treating various cancers, including metastatic melanoma. But regardless of cancer type, checkpoint blockade only helps some patients because most are resistant to PD-1 blockade, the researchers said. Tumor specimens from nonresponders have been found to lack CD8+ T cells, leaving anti-PD-1 antibodies without an effective target.

To see if attracting CD8+ T cells into tumors helped surmount this obstacle, the researchers treated 21 patients with advanced melanoma with pembrolizumab and T-vec, an intratumorally administered, genetically modified clinical herpes simplex virus-1 strain approved for treating melanoma. Patients first received up to 4 mL T-vec (106 plaque-forming units [pfu] per mL) to induce a protective immune response. Three weeks later, they started receiving to 4 mL (108 pfu/mL) T-vec plus 200 mg intravenous pembrolizumab every 2 weeks.

Thirteen patients (62%) showed at least a partial response, and seven (33%) had a complete response based on immune criteria. Notably, 9 of 13 (69%) patients with baseline tumor CD8+ densities below 1,000 cells/mm2 responded to combination treatment, as did three of five patients with low baseline IFN-gamma signatures.

“There was only one baseline biopsy that was scored as PD-L1 negative, but that patient went on to have a complete response to the combined therapy,” the researchers wrote. “Patients who responded to combination therapy had increased CD8+ T cells, elevated PD-L1 protein expression, [and] IFN-gamma gene expression on several cell subsets in tumors after [T-vec] treatment. Response to combination therapy did not appear to be associated with baseline CD8+ T cell infiltration or baseline IFN-gamma signature.” Increased levels of circulating immune cells and shrinkage of untreated tumors both suggested that intratumoral T-vec injections led to systemic effects, they added.

Dr. Antoni Ribas
The most common treatment-related adverse events were fatigue (62%), chills (48%), and fever (43%), which occur with intratumoral T-vec therapy, said the investigators. Serious adverse events included grade 1 cytokine-release syndrome deemed possibly related to combination therapy, and one case each of aseptic meningitis, autoimmune hepatitis, and pneumonitis attributed to pembrolizumab. Ongoing studies include a phase 3 trial (NCT02263508) of the combination regimen and a study of immune biomarkers of the inflammatory effects of T-vec on tumors (NCT02366195).

The Food and Drug Administration has approved a biosimilar to bevacizumab (Avastin) for the treatment of certain colorectal, lung, brain, kidney, and cervical cancers.

 

Bevacizumab-awwb is the first biosimilar approved in the United States for the treatment of cancer, the FDA said in a press release.

Approval is based on structural and functional characterization, animal study data, human pharmacokinetic and pharmacodynamics data, clinical immunogenicity data, and other clinical safety and effectiveness data that demonstrate bevacizumab-awwb is biosimilar to bevacizumab, the FDA said.

Approved indications include:

• Metastatic colorectal cancer, in combination with intravenous 5-fluorouracil-based chemotherapy for first- or second-line treatment.

• Metastatic colorectal cancer, in combination with fluoropyrimidine-irinotecan–based or fluoropyrimidine-oxaliplatin–based chemotherapy for the second-line treatment of patients who have progressed on a first-line bevacizumab product–containing regimen.

• Non-squamous non–small cell lung cancer, in combination with carboplatin and paclitaxel for first line treatment of unresectable, locally advanced, recurrent, or metastatic disease.

• Glioblastoma with progressive disease following prior therapy, based on improvement in objective response rate.

• Metastatic renal cell carcinoma, in combination with interferon alfa.

• Cervical cancer that is persistent, recurrent, or metastatic, in combination with paclitaxel and cisplatin or paclitaxel and topotecan.

Common expected side effects of the biosimilar include epistaxis, headache, hypertension, rhinitis, proteinuria, taste alteration, dry skin, hemorrhage, lacrimation disorder, back pain, and exfoliative dermatitis.

Serious expected side effects include perforation or fistula, arterial and venous thromboembolic events, hypertension, posterior reversible encephalopathy syndrome, proteinuria, infusion-related reactions, and ovarian failure. Women who are pregnant should not take bevacizumab-awwb.

The biosimilar to bevacizumab carries a similar boxed warning regarding the increased risk of gastrointestinal perforations; surgery and wound healing complications; and severe or fatal pulmonary, gastrointestinal, central nervous system, and vaginal hemorrhage.

The biosimilar approval was granted to Amgen, which will market the drug under the trade name Mvasi.

New data prompt update to ACC guidance on nonstatin LDL lowering

Article Type

Fri, 01/18/2019 - 17:01

 

The American College of Cardiology Task Force on Expert Consensus Decision Pathways has released a “focused update” for the 2016 ACC Expert Consensus Decision Pathway (ECDP) on the role of nonstatin therapies for LDL-cholesterol lowering in the management of atherosclerotic cardiovascular disease (ASCVD) risk.

The update was deemed by the ECDP writing committee to be desirable given the additional evidence and perspectives that have emerged since the publication of the 2016 version, particularly with respect to the efficacy and safety of proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors for the secondary prevention of ASCVD, as well as the best use of ezetimibe in addition to statin therapy after acute coronary syndrome.

Dr. Donald M. Lloyd-Jones
“This ECDP addresses current gaps in care for LDL-C lowering to reduce ASCVD risk and provides recommendations that build on the evidence base established by the 2013 [American College of Cardiology/American Heart Association] cholesterol guideline,” explained the committee, which was chaired by Donald M. Lloyd-Jones, MD, of Northwestern University, Chicago(J Am Coll Cardiol. 2017. doi: 10.1016/j.jacc.2017.07.745)

The ECDP algorithms endorse the four evidence-based statin benefit groups identified in the 2013 guidelines (adults aged 21 and older with clinical ASCVD, adults aged 21 and older with LDL-C of 190 mg/dL or greater, adults aged 40-75 years without ASCVD but with diabetes and with LDL-C of 70-189 mg/dL, and adults aged 40-75 without ASCVD or diabetes but with LDL-C of 70-189 mg/dL and an estimated 10-year risk for ASCVD of 7.5% or greater) and assume that the patient is currently taking or has attempted to take a statin, they noted.

Among the changes in the 2017 focused update are:

  • Consideration of new randomized clinical trial data for the PCSK9 inhibitors evolocumab and bococizumab. Namely, they included results from the cardiovascular outcomes trials FOURIER (Further Cardiovascular Outcomes Research with PCSK9 Inhibition in Subjects with Elevated Risk) and SPIRE-1 and SPIRE-2 (Studies of PCSK9 Inhibition and the Reduction of Vascular Events), which were published in early 2017.
  • An adjustment in the ECDP algorithms with respect to thresholds for consideration of net ASCVD risk reduction. The 2016 ECDP thresholds for risk reduction benefit were percent reduction in LDL-C with consideration of absolute LDL-C level in patients with clinical ASCVD, baseline LDL-C of 190 mg/dL or greater, and primary prevention. In patients with diabetes with or without clinical ASCVD, clinicians were allowed to consider absolute LDL-C and/or non-HDL-cholesterol levels. In the 2017 ECDP update, the thresholds are percent reduction in LDL-C with consideration of absolute LDL-C or non-HDL-C levels for patients in each of the four statin benefit groups. This change was based on the inclusion criteria of the FOURIER trial, the ongoing ODYSSEY Outcomes trial (Evaluation of Cardiovascular Outcomes after an Acute Coronary Syndrome During Treatment with Alirocumab), and the SPIRE-2 trial, all of which included non-HDL-C thresholds. “In alignment with these inclusion criteria, the 2017 Focused Update includes both LDL-C and non-HDL-C thresholds for evaluation of net ASCVD risk-reduction benefit when considering the addition of nonstatin therapies for patients in each of the four statin benefit groups” the update explained.
  • An expansion of the threshold for consideration of net ASCVD risk-reduction benefit from a reduction of LDL C of at least 50%, as well as consideration of LDL-C less than 70 mg/dL or non-HDL-C less than 100 mg/dL for all patients (that is, both those with and those without comorbidities) who have clinical ASCVD and baseline LDL-C of 70-189 mg/dL. The 2016 ECDP had different thresholds for those with versus those without comorbidities. This change was based on findings from the FOURIER trial and the IMPROVE-IT (Improved Reduction of Outcomes: Vytorin Efficacy International Trial).“Based on consideration of all available evidence, the consensus of the writing committee members is that lower LDL-C levels are safe and optimal in patients with clinical ASCVD due to [their] increased risk of recurrent events,” they said.
  • An expanded recommendation on the use of ezetimibe and PCSK9 inhibition. The 2016 ECDP stated that “if a decision is made to proceed with the addition of nonstatin therapy to maximally tolerated statin therapy, it is reasonable to consider the addition of ezetimibe as the initial agent and a PCSK9 inhibitor as the second agent.” However, based on the FOURIER findings, the ongoing ODYSSEY Outcomes trial, and the IMPROVE-IT trial, the 2017 Focused Update states that, if such a decision is made in patients with clinical ASCVD with comorbidities and baseline LDL-C of 70-189 mg/dL, it is reasonable to weigh the addition of either ezetimibe or a PCSK9 inhibitor in light of “considerations of the additional percent LDL-C reduction desired, patient preferences, costs, route of administration, and other factors.” The update also spells out considerations that may favor the initial choice of ezetimibe versus a PCSK9 inhibitor (such as requiring less than 25% additional lowering of LDL-C, an age of over 75 years, cost, and other patient factors and preferences) .
  • Additional factors, based on the FOURIER trial results and inclusion criteria, that may be considered for the identification of higher-risk patients with clinical ASCVD. The 2016 ECDP included on this list diabetes, a recent ASCVD event, an ASCVD event while already taking a statin, poorly controlled other major ASCVD risk factors, elevated lipoprotein, chronic kidney disease, symptomatic heart failure, maintenance hemodialysis, and baseline LDL-C of at least 190 mg/dL not due to secondary causes. The 2017 update added being 65 years or older, prior MI or nonhemorrhagic stroke, current daily cigarette smoking, symptomatic peripheral artery disease with prior MI or stroke, history of non-MI related coronary revascularization, residual coronary artery disease with at least 40% stenosis in at least two large vessels, HDL-C less than 40 mg/dL for men and less than 50 mg/dL for women, high-sensitivity C-reactive protein greater than 2 mg/L, and metabolic syndrome.
 

 

The content of the full ECDP has been changed in accordance with these updates and now includes more extensive and detailed guidance for decision making – both in the text and in treatment algorithms.

Aspects that remain unchanged include the decision pathways and algorithms for the use of ezetimibe or PCSK9 inhibitors in primary prevention patients with LDL-C less than 190 mg/dL or in those without ASCVD and LDL-C of 190 mg/dL or greater unattributable to secondary causes.

In addition to other changes made for the purpose of clarification and consistency, recommendations regarding bile acid–sequestrant use were downgraded; these are now only recommended as optional secondary agents for consideration in patients who cannot tolerate ezetimibe.

“[These] recommendations attempt to provide practical guidance for clinicians and patients regarding the use of nonstatin therapies to further reduce ASCVD risk in situations not covered by the guideline until such time as the scientific evidence base expands and cardiovascular outcomes trials are completed with new agents for ASCVD risk reduction,” the committee concluded.

Dr. Lloyd-Jones reported having no disclosures.

Postpartum sepsis risk persists after 6 weeks

Article Type

Fri, 01/18/2019 - 17:01

 

– The risk of sepsis after delivery persists beyond 6 weeks, the traditional point at which women are thought to be in the clear, according to investigators from Stanford (Calif.) University.

The team analyzed 506 sepsis hospitalizations following delivery, culled from almost 2 million live births in California from 2008-2012; 199 (39%) were at or before 6 weeks postpartum, and 310 (61%) were after 6 weeks, out to a year.

“Going into this, our view was that sepsis cases before 6 weeks would be due to obstetrical causes, and cases after 6 weeks would be due to [nonobstetrical causes],” said senior investigator Ronald Gibbs, MD, clinical professor of obstetrics and gynecology at Stanford. But that’s not what the team found.

Dr. Ronald Gibbs


In both the early and late admission groups, early preterm delivery was one of the leading risks for postpartum sepsis and other risk factors were largely the same. Pyelonephritis and pneumonia were by far the most common diagnoses in both groups, accounting for more than 70% of cases. The rank order of causative organisms was the same whether women presented before 6 weeks or after: gram-negative bacteria, staphylococcus, and streptococcus.

“In view of this, we think the risk for sepsis goes beyond 6 weeks,” Dr. Gibbs said at the annual scientific meeting of the Infectious Diseases Society for Obstetrics and Gynecology. Although women were admitted largely for nonuterine infections, “the reservoir of infection could be in the uterus,” with later seeding to the urinary tract or lungs. “I think there’s a chronic intrauterine infection that sets women up for” both early preterm birth and later sepsis, he added.

“These late admissions would probably go to a nonobstetrical service, but we are thinking that there may be a pelvic origin related to something that went on at delivery. I can’t really say that we ought to change our practice, but it sets the stage for looking at that. Finding that late [admissions for sepsis] have a lot in common with the early admissions and are probably related to the pregnancy really reorders the thinking,” Dr. Gibbs said.

The team found that among women who were delivered at 24-28 weeks, the adjusted odds ratio was 8.6 (95% confidence interval[CI], 4.4-17.1) for early and 4.2 (95% CI, 1.9-9.0) for late postpartum sepsis admission, even after delivery mode, maternal comorbidities, maternal age, “and everything else we could think of” were controlled for, said lead investigator Megan Foeller, MD, a maternal-fetal medicine fellow at Stanford.

Dr. Megan Foeller
The finding dovetails with the fact that earlier preterm birth is more likely than is later preterm birth to be due to an infectious inflammatory process in the womb, Dr. Gibbs noted.

A body mass index above 35 kg/m2 also increased the risk for sepsis admission, as did government-provided insurance, primary cesarean delivery, a failed trial of labor after a previous cesarean, and four or more previous deliveries.

Postoperative infection, acute hepatic failure, acute renal failure, acute respiratory failure, and heart failure during the delivery hospitalization greatly increased the risk of subsequent sepsis, as well.

The findings help define a group of women who likely need especially close follow-up after delivery to prevent sepsis, Dr. Foeller said.

Sepsis was defined in the study by ICD-9 codes for septicemia plus acute organ dysfunction.

There was no industry funding for the work and the investigators reported having no relevant financial disclosures.

The rank order of causative organisms was the same whether women presented before 6 weeks or after: gram-negative bacteria, staphylococcus, and streptococcus.

“In view of this, we think the risk for sepsis goes beyond 6 weeks,” Dr. Gibbs said at the annual scientific meeting of the Infectious Diseases Society for Obstetrics and Gynecology. Although women were admitted largely for nonuterine infections, “the reservoir of infection could be in the uterus,” with later seeding to the urinary tract or lungs. “I think there’s a chronic intrauterine infection that sets women up for” both early preterm birth and later sepsis, he added.

“These late admissions would probably go to a nonobstetrical service, but we are thinking that there may be a pelvic origin related to something that went on at delivery. I can’t really say that we ought to change our practice, but it sets the stage for looking at that. Finding that late [admissions for sepsis] have a lot in common with the early admissions and are probably related to the pregnancy really reorders the thinking,” Dr. Gibbs said.

The team found that among women who were delivered at 24-28 weeks, the adjusted odds ratio was 8.6 (95% confidence interval[CI], 4.4-17.1) for early and 4.2 (95% CI, 1.9-9.0) for late postpartum sepsis admission, even after delivery mode, maternal comorbidities, maternal age, “and everything else we could think of” were controlled for, said lead investigator Megan Foeller, MD, a maternal-fetal medicine fellow at Stanford.

The finding dovetails with the fact that earlier preterm birth is more likely than is later preterm birth to be due to an infectious inflammatory process in the womb, Dr. Gibbs noted.

A body mass index above 35 kg/m2 also increased the risk for sepsis admission, as did government-provided insurance, primary cesarean delivery, a failed trial of labor after a previous cesarean, and four or more previous deliveries.

Postoperative infection, acute hepatic failure, acute renal failure, acute respiratory failure, and heart failure during the delivery hospitalization greatly increased the risk of subsequent sepsis, as well.

The findings help define a group of women who likely need especially close follow-up after delivery to prevent sepsis, Dr. Foeller said.

Sepsis was defined in the study by ICD-9 codes for septicemia plus acute organ dysfunction.

There was no industry funding for the work and the investigators reported having no relevant financial disclosures.

 

– The risk of sepsis after delivery persists beyond 6 weeks, the traditional point at which women are thought to be in the clear, according to investigators from Stanford (Calif.) University.

The team analyzed 506 sepsis hospitalizations following delivery, culled from almost 2 million live births in California from 2008-2012; 199 (39%) were at or before 6 weeks postpartum, and 310 (61%) were after 6 weeks, out to a year.

“Going into this, our view was that sepsis cases before 6 weeks would be due to obstetrical causes, and cases after 6 weeks would be due to [nonobstetrical causes],” said senior investigator Ronald Gibbs, MD, clinical professor of obstetrics and gynecology at Stanford. But that’s not what the team found.

PROTECT trial: No DFS benefit with adjuvant pazopanib for high-risk RCC

Fri, 01/04/2019 - 13:40

 

Adjuvant pazopanib provided no disease-free survival benefit compared with placebo in the randomized phase 3 PROTECT trial of patients with locally advanced renal cell carcinoma at high risk for relapse after nephrectomy.

In the primary analysis for disease-free survival among 571 patients treated for 1 year with 600 mg of pazopanib and 564 who received placebo, no significant improvement was seen with pazopanib (hazard ratio, 0.86). In a follow-up analysis 12 months later, the hazard ratio was 0.94. Secondary analysis in 403 additional patients who were treated with 800 mg of pazopanib before the dose was lowered to 600 mg due to intolerance and toxicity attrition showed a benefit with pazopanib (HR, 0.69), but this group represented only a third of the study population, reported Robert J. Motzer, MD, of Memorial Sloan Kettering Cancer Center, New York, and his colleagues. The study results were published online in the Journal of Clinical Oncology.

Dr. Robert J. Motzer


Common adverse events leading to treatment discontinuation included increased alanine transaminase and aspartate transaminase levels, which occurred in 16% and 5% of patients treated with 600 mg, respectively, and in 18% and 7% of patients treated with 800 mg, respectively. Four grade 5 adverse events occurred in the pazopanib groups (vs. 2 in the placebo group), and one of the deaths (in a patient who received 800 mg dosing) involved cardiomyopathy that was considered to be related to treatment, the investigators said (J Clin Oncol. 2017 Sep 13. doi: 10.1200/JCO.2017.73.5324).

The study comprised adults with resected pT2 or pT3 and greater disease, including N1, clear cell renal cell carcinoma, who were enrolled between Dec. 9, 2010, and Sept. 10, 2013, from 263 centers in 26 countries. Primary analysis was done after 350 disease-free events occurred in the intent-to-treat population receiving 600 mg.

The difference in treatment effect between those receiving 600 mg and 800 mg of pazopanib could be explained by the different starting dose, or by better performance of the placebo arm in the 600 mg group, the investigators noted.

As for overall survival, the results are inconclusive, because the data are not mature, they said.

Novartis supported the study. Dr. Mercer reported consulting or advisory roles with Pfizer, Novartis, Eisai, and Exelixis, and research funding to his institution from Pfizer, GlaxoSmithKline, Bristol-Myers Squibb, Eisai, Novartis, and Genentech. Numerous coauthors also reported financial relationships with pharmaceutical companies.

No increased overall cardiovascular risk seen with exenatide use

Article Type

Tue, 05/03/2022 - 15:22

 

Patients with type 2 diabetes who took once-daily exenatide did not appear to have an increase in their overall cardiovascular risk, compared with those who took placebo, a large randomized trial demonstrated.

“We did not observe any specific safety issues during our trial; there was no adverse signal with respect to heart failure, despite the higher mean heart rate in the exenatide group than in the placebo group, and events of acute pancreatitis and pancreatic cancer were rare, with similar rates in the two groups,” according to researchers led by Rury R. Holman, F.Med.Sci. Their study was published online Sept. 14 in the New England Journal of Medicine, and was presented at the annual meeting of the European Association for the Study of Diabetes.

For the trial, which was funded by Amylin Pharmaceuticals and known as the Exenatide Study of Cardiovascular Event Lowering (EXSCEL), the researchers randomly assigned 14,752 patients with type 2 diabetes at 687 sites in 35 countries to receive subcutaneous injections of extended-released exenatide at a dose of 2 mg, or matching placebo once per week, from June 18, 2010, through Sept. 16, 2015. The patients were followed for a median of 3.2 years and the main outcome of interest was the first occurrence of death from cardiovascular causes, nonfatal myocardial infarction, or stroke.

Dr. Rury R. Holman
Dr. Holman, professor of diabetic medicine at Oxford (England) University and director of the University of Oxford Diabetes Trials Unit of the Oxford Center for Diabetes, England, and his associates reported that 10,782 of the 14,752 patients (73.1%) had previous cardiovascular disease. A primary composite outcome event occurred in 11.4% of patients in the exenatide group, compared with 12.2% of those in the placebo group, which translated into a hazard ratio of 0.91.

In the meantime, the intention-to-treat analysis revealed that exenatide was noninferior to placebo with respect to safety (P less than .001) but was not superior to placebo with respect to safety (P = .06). The researchers observed no significant differences between the two groups in the rates of death from cardiovascular causes, fatal or nonfatal MI, or stroke, hospitalization for heart failure or for acute coronary syndrome, or in the incidence of cute pancreatitis, pancreatic cancer, medullary thyroid carcinoma, and serious adverse events.

“The pragmatic design of the trial included integration with usual care and wide-ranging eligibility criteria,” the researchers wrote. “For example, patients with any degree of cardiovascular risk who were at least 18 years of age (with no upper age limit) were eligible. To further augment the potential generalizability of any findings, we evaluated the cardiovascular effect of once-weekly extended-release exenatide in the usual-care setting by maintaining the focus of management of diabetes and cardiovascular risk with the usual-care provider.”

The researchers acknowledged certain limitations of the study, including the rate of premature discontinuation of the trial regimen, “which was driven by patient decision. We speculate that probable factors for discontinuation were the complexity of the first-generation injection device that was used and the fact that our trial had no run-in period.”

The trial was conducted jointly by the Duke Clinical Research Institute and the University of Oxford Diabetes Trial Unit, in collaboration with Amylin Pharmaceuticals. Dr. Holman and his coauthors reported having numerous financial ties to the pharmaceutical industry.

Early decision for Fellows applications is Sept. 15. Apply now!

SHM’s Fellows designation is a prestigious way to differentiate yourself among your peers in hospital medicine. There are currently over 2,000 hospitalists who have earned the Fellow in Hospital Medicine (FHM) or Senior Fellow in Hospital Medicine (SFHM) designation by demonstrating core values of leadership, teamwork, and quality improvement.

“I was encouraged to consider SHM’s Fellow designation by other members of an SHM committee that I belonged to. Although reluctant at first, I realized that this was an opportunity to really confirm that I was a career hospitalist. The application process itself allowed me to objectively evaluate the work I had done to date and how it fit into my overall career plan. I believe that this FHM designation has fostered connections in the HM community and within my own institution that may not have been open to me before.” – Dr. Patricia Seymour, MD, FAAFP, FHM
