Pharmacology

The U.S. Food and Drug Administration has approved a 2.4 mg/week subcutaneous dose of the glucagonlike peptide–1 (GLP-1) receptor agonist semaglutide (Wegovy, Novo Nordisk) for weight loss.

Specifically, this drug format and dosage are approved as an adjunct to a reduced-calorie diet and increased physical activity to treat adults who have obesity (body mass index [BMI] ≥ 30 kg/m²) or are overweight (BMI ≥ 27 kg/m²) with at least one weight-related comorbidity.

Semaglutide “induces weight loss by reducing hunger, increasing feelings of fullness, and thereby helping people eat less and reduce their calorie intake,” according to a company statement.

Novo Nordisk plans to launch Wegovy later this month in the United States. The prescribing information can be found here.

This weight-loss drug is currently under review by the European Medicines Agency.

Several experts told Medscape that they believe the approval of this drug – as long as it is reimbursed – has the potential to change the paradigm of care when it comes to weight loss.


 

‘Game changer’ drug tested in STEP clinical trial program

The favorable FDA ruling is based on results from the Semaglutide Treatment Effect in People With Obesity (STEP) program of four phase 3 clinical trials that tested the drug’s safety and efficacy in more than 4,500 adults with overweight or obesity obesity who were randomized to receive a reduced a calorie meal plan and increased physical activity (placebo) or this lifestyle intervention plus semaglutide.

The four 68-week trials of subcutaneous semaglutide 2.4 mg/week versus placebo were published in February and March 2021.

As previously reported by this news organization, all trials were in adults with overweight or obesity:

•  was in 1,961 adults (N Engl J Med. 2021 March 18;384:989-1002).
•  was in 1,210 adults who also had diabetes (Lancet. 2021 Mar 13;397;971-84).
•  was in 611 adults, where those in the treatment group also underwent an intensive lifestyle intervention (JAMA. 2021 Feb 24;325:1403-13.
•  was in 803 adults who had reached a target dose of 2.4 mg semaglutide after a 20-week run-in (and the trial examined further weight loss in the subsequent 48 weeks) (JAMA 2021 Mar 23;325:1414-25).

In the STEP 1, 2, and 4 trials of individuals with overweight and obesity, those in the semaglutide groups attained a 15%-18% weight loss over 68 weeks.

The dosage was well-tolerated. The most common side effects were gastrointestinal, and they were transient and mild or moderate in severity.

The side effects, contraindications, and a black box warning about thyroid C-cell tumors are spelled out in the prescribing information.

A coauthor of the STEP 1 trial, Rachel Batterham, MBBS, PhD, of the Centre for Obesity Research at University College London, said at the time of publication: “The findings of this study represent a major breakthrough for improving the health of people with obesity.”

“No other drug has come close to producing this level of weight loss – this really is a gamechanger. For the first time, people can achieve through drugs what was only possible through weight-loss surgery,” she added.
 

Welcome Addition, But Will Insurance Coverage, Price Thwart Access?

Thomas A. Wadden, PhD, from the Perelman School of Medicine at the University of Pennsylvania, Philadelphia, and lead author of STEP 3, commented in an email to this news organization that “semaglutide 2.4 mg appears to be the breakthrough in weight management that healthcare providers and their patients with obesity have been waiting for.”

The mean 15% weight loss at 68 weeks is nearly twice what is seen with other FDA-approved anti-obesity medications, he noted, and moreover, 70% of patients taking semaglutide lost at least 10% of their initial weight, which is associated with clinically meaningful improvements in obesity-related type 2 diabetes, hypertension, obstructive sleep apnea, and impaired quality of life.

And “nearly one-third of users are likely to lose 20% or more of their starting weight, an outcome which eludes traditional diet and exercise interventions and which approaches weight losses produced by the most widely performed bariatric surgery, sleeve gastrectomy (with mean losses of 25% of initial weight at 1 year).” Dr. Wadden stressed.

Thus “the efficacy of semaglutide 2.4 mg, combined with its favorable safety profile, makes this medication a potential game changer,” he summarized, echoing Dr. Batterham.

However, insurance coverage and price could block uptake.

“I hope that the millions of people – in the U.S. and worldwide – who could benefit from this medication eventually will have access to it,” said Dr. Wadden. “In the U.S., the coverage of anti-obesity medications by insurers and employers will need to improve to ensure this happens, and the medication must be reasonably priced. These changes are critical to making this medication the game changer it could be.”

“This approval is an important development,” Scott Kahan, MD, director of the National Center for Weight and Wellness, Washington, who was not involved in the clinical trials of this drug, similarly wrote in an email.

“In a field with relatively few medication options, the availability of additional obesity pharmacotherapy agents is welcome,” he said. “In particular, semaglutide has shown impressive efficacy and safety data; as such it should be a valuable clinical option for many patients.”

However, it is concerning that “access to obesity treatments has traditionally been a challenge,” Dr. Kahan warned. “Novo Nordisk’s other obesity medication, Saxenda, has been a valuable tool, but one that exceedingly few patients are able to utilize due to minimal insurance reimbursement and very high cost.”

“It remains to be seen how accessible semaglutide will be for patients,” according to Dr. Kahan, “Still, if the challenge of limited coverage and high cost can be mitigated, this medication has a chance to significantly change the current paradigm of care, which until till now has included minimal use of pharmacotherapy outside specialty clinics,” he maintains.

Subcutaneous semaglutide at doses up to 1 mg/week (Ozempic, Novo Nordisk), which comes as prefilled pens at doses of 0.5 mg or 1.0 mg, is already approved for the treatment of type 2 diabetes.

The company is also applying for approval for a higher dose of semaglutide, 2 mg/week, for use in type 2 diabetes, and has just resubmitted its label expansion application to the FDA, after the agency issued a refusal to file letter in March.

And in September 2019, the FDA approved oral semaglutide (Rybelsus, Novo Nordisk), in doses of 7 and 14 mg/day, to improve glycemic control in type 2 diabetes, making it the first GLP-1 receptor agonist available in tablet form.
 

CVOT and oral format trials for obesity on the horizon

The ongoing Semaglutide Effects on Heart Disease and Stroke in Patients With Overweight or Obesity (SELECT) trial will shed light on cardiovascular outcomes after 2.5-5 years in patients with cardiovascular disease and overweight or obesity but without type 2 diabetes. Participants will receive semaglutide in doses up to a maximum of 2.4 mg/week, or placebo, as an adjunct to lifestyle recommendations focused on cardiovascular risk reduction. The study is expected to complete in 2023.

And Novo Nordisk plans to initiate a global 68-week phase 3 trial in the second half of 2021 on the efficacy and safety of oral semaglutide 50 mg compared with placebo in 1000 people with obesity or overweight and comorbidities.

A subcutaneous dose of the second-generation glycoprotein IIb/IIIa inhibitor RUC-4 achieved rapid dose-dependent platelet inhibition in patients with ST-segment elevation MI (STEMI) undergoing stenting in the CEL-02 study.

Platelet inhibition occurred within 15 minutes among the 27 patients, and wore off rapidly, with almost 50% of platelet function recovered within 122 minutes.

The drug was well tolerated, with no thrombocytopenia in the first 72 hours after administration, one injection-site reaction, and two major bleeds likely caused by catheter-based trauma to the proximal radial artery, reported Jurrien ten Berg, MD, PhD, St. Antonius Hospital, Nieuwegein, the Netherlands.

The results were reported during the annual meeting of the European Association of Percutaneous Cardiovascular Interventions (EuroPCR 2021) and published simultaneously in EuroIntervention.

Dr. ten Berg noted that there is a need for drugs like RUC-4 in the early treatment of STEMI because oral P2Y12 inhibitors have a “seriously delayed” onset by about 2-4 hours. Prehospital use of the glycoprotein inhibitor (GPI) tirofiban was shown to improve reperfusion and late outcomes in the ON-TIME 2 trial, but GPIs require continuous intravenous administration and are associated with thrombocytopenia.

“Since RUC-4 is unique among small-molecule GPI in not inducing the receptor to undergo a major conformational change that has been implicated in the development of thrombocytopenia, it is possible that RUC-4 may be associated with fewer episodes of thrombocytopenia than current GPI,” the authors wrote.

RUC-4, also called zalunfiban, can be delivered with a single subcutaneous dose and, in a phase 1 study, demonstrated platelet inhibition within 15 minutes and was well tolerated up to a dose of 0.075 mg/kg among healthy volunteers and patients with stable coronary artery disease on aspirin.

In the CEL-02 study, 27 STEMI patients received a weight-adjusted subcutaneous injection of RUC-4 before primary percutaneous coronary intervention (PCI) in escalating doses of 0.075 mg/kg, 0.090 mg/kg, and 0.110 mg/kg. Patients were given standard treatment in the ambulance, which included aspirin (93%), ticagrelor (93%), and unfractionated heparin (96%). The activated clotting time was less than 200 seconds in 92% of patients who received additional heparin during cardiac catheterization.

The patients’ mean age was 62 years, 26% were women, and 96% were White. Pharmacodynamic data were available for 24 patients.

The average platelet inhibition 15 minutes after the injection was 77.5%, 87.5%, and 91.7%, respectively, for the three escalating doses (P = .002 for trend).

The primary endpoint of at least 77% inhibition of the iso-TRAP channel – which corresponds to 80% inhibition of light transmission aggregometry stimulated by 20 mcM adenosine diphosphate within 15 minutes – was achieved in three of eight patients at the lowest dose and in seven of eight patients at the middle and highest doses.

“Single-dose subcutaneous RUC-4 induces a fast, potent dose-dependent response of platelet inhibition in patients with STEMI presenting for primary PCI,” Dr. ten Berg concluded. “It is therefore promising for prehospital platelet inhibition in STEMI patients, and the results support further research on clinical benefit.”

The double-blind, randomized phase 2b CELEBRATE trial is underway, evaluating 1,668 STEMI patients treated with a 0.110 mg/kg or 0.130 mg/kg dose of RUC-4 or placebo in the ambulance. The coprimary outcomes are restoration of coronary artery blood flow and resolution of ST-segment deviation post-PCI/angiography. Primary completion is set for March 2023.

Marco Valgimigli, MD, who was not involved in the study, said in an interview that RUC-4 has “some theoretical advantages, compared with conventional IIb/IIIa inhibitors, namely the absence of thrombocytopenia which is, however, relatively rare, especially with tirofiban or eptifibatide.”

The subcutaneous approach may also offer an advantage. Yet, if the administration of RUC-4 is “to happen in the ambulance – a setting where an IV line is usually established – whether the subcutaneous versus IV administration of the treatment proves to be advantageous remains to be seen,” said Dr. Valgimigli, from Cardiocentro Ticino Institute, Ente Ospedaliero Cantonale, Lugano, Switzerland.

“We would need to see the results of large randomized trials embracing this treatment option before a clinical decision can be made, especially considering that IIb/IIa inhibitors in the ambulance have been tested in the past but ultimately abandoned,” he said.

Limitations of the study are its open-label design, the fact that iso-TRAP channel assay data were not reported by the VeryifyNow instrument and had to be calculated from the raw data, and the fact that the timing of the RUC-4 injection immediately before PCI does not fully resemble the expected use of RUC-4 in clinical practice, where RUC-4 would be administered at the same time as the aspirin, ticagrelor, and heparin, and about an hour before PCI, ten Berg and colleagues wrote.

CeleCor Therapeutics sponsored the study and provided study materials. Dr. ten Berg reported receiving lecture or consultancy fees from AstraZeneca, Eli Lilly, Daiichi Sankyo, The Medicines Company, AccuMetrics, Boehringer Ingelheim, Bristol-Myers Squibb, Pfizer, Bayer, Ferrer, and Idorsia, and institutional research grants from ZonMw and AstraZeneca. Coauthor Barry S. Coller is an inventor of RUC-4 and a founder, equity holder, and consultant to CeleCor. He also receives royalties from Centocor/Janssen and the VerifyNow assays. Dr. Valgimigli has received grants from Abbott, Terumo, Medicure, and AstraZeneca, and personal fees from Abbott, Chiesi, Bayer, Daiichi Sankyo, Amgen, Terumo, Alvimedica, AstraZeneca, Biosensors, and Idorsia.

“We would need to see the results of large randomized trials embracing this treatment option before a clinical decision can be made, especially considering that IIb/IIa inhibitors in the ambulance have been tested in the past but ultimately abandoned,” he said.

Limitations of the study are its open-label design, the fact that iso-TRAP channel assay data were not reported by the VeryifyNow instrument and had to be calculated from the raw data, and the fact that the timing of the RUC-4 injection immediately before PCI does not fully resemble the expected use of RUC-4 in clinical practice, where RUC-4 would be administered at the same time as the aspirin, ticagrelor, and heparin, and about an hour before PCI, ten Berg and colleagues wrote.

A subcutaneous dose of the second-generation glycoprotein IIb/IIIa inhibitor RUC-4 achieved rapid dose-dependent platelet inhibition in patients with ST-segment elevation MI (STEMI) undergoing stenting in the CEL-02 study.

Platelet inhibition occurred within 15 minutes among the 27 patients, and wore off rapidly, with almost 50% of platelet function recovered within 122 minutes.

The drug was well tolerated, with no thrombocytopenia in the first 72 hours after administration, one injection-site reaction, and two major bleeds likely caused by catheter-based trauma to the proximal radial artery, reported Jurrien ten Berg, MD, PhD, St. Antonius Hospital, Nieuwegein, the Netherlands.

The results were reported during the annual meeting of the European Association of Percutaneous Cardiovascular Interventions (EuroPCR 2021) and published simultaneously in EuroIntervention.

Dr. ten Berg noted that there is a need for drugs like RUC-4 in the early treatment of STEMI because oral P2Y12 inhibitors have a “seriously delayed” onset by about 2-4 hours. Prehospital use of the glycoprotein inhibitor (GPI) tirofiban was shown to improve reperfusion and late outcomes in the ON-TIME 2 trial, but GPIs require continuous intravenous administration and are associated with thrombocytopenia.

“Since RUC-4 is unique among small-molecule GPI in not inducing the receptor to undergo a major conformational change that has been implicated in the development of thrombocytopenia, it is possible that RUC-4 may be associated with fewer episodes of thrombocytopenia than current GPI,” the authors wrote.

RUC-4, also called zalunfiban, can be delivered with a single subcutaneous dose and, in a phase 1 study, demonstrated platelet inhibition within 15 minutes and was well tolerated up to a dose of 0.075 mg/kg among healthy volunteers and patients with stable coronary artery disease on aspirin.

In the CEL-02 study, 27 STEMI patients received a weight-adjusted subcutaneous injection of RUC-4 before primary percutaneous coronary intervention (PCI) in escalating doses of 0.075 mg/kg, 0.090 mg/kg, and 0.110 mg/kg. Patients were given standard treatment in the ambulance, which included aspirin (93%), ticagrelor (93%), and unfractionated heparin (96%). The activated clotting time was less than 200 seconds in 92% of patients who received additional heparin during cardiac catheterization.

The patients’ mean age was 62 years, 26% were women, and 96% were White. Pharmacodynamic data were available for 24 patients.

The average platelet inhibition 15 minutes after the injection was 77.5%, 87.5%, and 91.7%, respectively, for the three escalating doses (P = .002 for trend).

The primary endpoint of at least 77% inhibition of the iso-TRAP channel – which corresponds to 80% inhibition of light transmission aggregometry stimulated by 20 mcM adenosine diphosphate within 15 minutes – was achieved in three of eight patients at the lowest dose and in seven of eight patients at the middle and highest doses.

“Single-dose subcutaneous RUC-4 induces a fast, potent dose-dependent response of platelet inhibition in patients with STEMI presenting for primary PCI,” Dr. ten Berg concluded. “It is therefore promising for prehospital platelet inhibition in STEMI patients, and the results support further research on clinical benefit.”

The double-blind, randomized phase 2b CELEBRATE trial is underway, evaluating 1,668 STEMI patients treated with a 0.110 mg/kg or 0.130 mg/kg dose of RUC-4 or placebo in the ambulance. The coprimary outcomes are restoration of coronary artery blood flow and resolution of ST-segment deviation post-PCI/angiography. Primary completion is set for March 2023.

Marco Valgimigli, MD, who was not involved in the study, said in an interview that RUC-4 has “some theoretical advantages, compared with conventional IIb/IIIa inhibitors, namely the absence of thrombocytopenia which is, however, relatively rare, especially with tirofiban or eptifibatide.”

The subcutaneous approach may also offer an advantage. Yet, if the administration of RUC-4 is “to happen in the ambulance – a setting where an IV line is usually established – whether the subcutaneous versus IV administration of the treatment proves to be advantageous remains to be seen,” said Dr. Valgimigli, from Cardiocentro Ticino Institute, Ente Ospedaliero Cantonale, Lugano, Switzerland.

The U.S. Food and Drug Administration has approved a once-daily oral medication, which is a combination of olanzapine and samidorphan (Lybalvi, Alkermes), for the treatment of schizophrenia and bipolar I disorder.

The drug is approved for the treatment of adults with schizophrenia and for adults with bipolar I disorder as a maintenance monotherapy or to treat acute manic or mixed episodes, as either monotherapy or an adjunct to lithium or valproate.

An atypical antipsychotic, the drug is a combination of olanzapine, an established antipsychotic medication, and samidorphan, a new chemical entity.

“Schizophrenia and bipolar I disorder are complex, chronic diseases, and there remains a persistent need for new medications with proven efficacy and safety. Olanzapine, a highly efficacious atypical antipsychotic, is associated with significant side effects, including weight gain that may impact patients’ treatment experiences and limit its use. With the efficacy of olanzapine and evidence of less weight gain in patients with schizophrenia, Lybalvi brings a welcome new addition to our medication arsenal,” René S. Kahn, MD, PhD, Esther and Joseph Klingenstein professor & chair, department of psychiatry and Behavioral Health System at the Icahn School of Medicine at Mount Sinai, New York, said in a company press release.

In a clinical development program, the drug demonstrated antipsychotic efficacy, safety, and tolerability, including significantly less weight gain than olanzapine in patients with schizophrenia in the ENLIGHTEN-2 study.

The FDA approved Lybalvi under the 505(b)(2) regulatory pathway based on data from 27 clinical studies, including 18 studies evaluating Lybalvi and nine studies evaluating samidorphan alone and the FDA’s findings of the safety and effectiveness of olanzapine in the treatment of bipolar I disorder and schizophrenia. Data suggest that olanzapine-associated weight gain is disease independent, the company reports.

“People living with schizophrenia or bipolar I disorder must evaluate both efficacy and tolerability when making treatment decisions,” Paul Gionfriddo, president and CEO of Mental Health America, said in the same company press release. “We are grateful that companies like Alkermes are driven to continue developing new treatment options in psychiatry that seek to address unmet needs of our community, and we applaud the FDA for considering the experiences of individuals living with these conditions.” 

Alkermes expects to make Lybalvi available for patients in the fourth quarter of 2021.

Combining minimally invasive endoscopic sleeve gastroplasty with a weekly injection of the glucagonlike peptide–1 agonist semaglutide (Ozempic, Novo Nordisk) leads to significantly greater weight loss than ESG alone in patients with diabetes and excess weight who are not candidates for bariatric surgery, new research shows.

During minimally invasive ESG, a flexible endoscope equipped with an endoscopic suturing device is inserted down the esophagus and into the stomach. The endoscopist then applies the sutures to the upper portion of the stomach, minimizing its size to restrict the amount of food a patient can ingest.

“Our stomachs can stretch back a bit, but we can use the suturing device again,” explained the lead investigator of the research Anna Carolina Hoff, MD, founder and clinical director of Angioskope Brazil in São José dos Campos.

“It’s important that patients with diabetes lose as much weight as possible because, if they lose about 10% of their total body weight, they have a great improvement in their glycemic levels, and some patients can even stop taking their [antidiabetic] medications,” Dr. Hoff said in an interview.

“And we found that by adding the GLP-1 agonist [semaglutide], we could increase weight loss from, on average, about 16%-18% of total body weight with ESG alone to up to 27%, so it’s a great metabolic combination,” she noted.

Dr. Hoff presented the findings at the annual Digestive Disease Week® (DDW).

Asked to comment, Scott Kahan, MD, MPH, director, National Center for Weight and Wellness, George Washington University, Washington, cautioned that it’s still early days for minimally invasive ESG.

“It is reasonable to assume that the long-term outcomes [with ESG] won’t be as good or durable over time as with bariatric surgery, but ... we will have to see.”

However, “we know that, typically, combinations of therapeutic options work better than a one-off option, so I think the real benefit of this study – outside the specific procedure and this specific medication – is that it is a very valuable proof-of-principle study showing that combinations do work better,” Dr. Kahan said in an interview.
 

Minimally invasive endoscopic sleeve gastroplasty

ESG is a surrogate for laparoscopic sleeve gastrectomy that can offer the benefits of such a procedure to those who don’t qualify for, or don’t wish to pursue, bariatric surgery. It can be performed at an earlier stage of disease, in those with a body mass index of 30 mg/kg², whereas generally people are not offered bariatric procedures unless they have a BMI of at least 35 with comorbidities or a BMI of at least 40 if they do not have comorbidities.

Subcutaneous semaglutide is already approved for the treatment of type 2 diabetes in adults at doses of up to 1 mg/week; higher doses are needed for weight loss. Novo Nordisk has been investigating higher doses for weight loss in the STEP trial program, which is now complete, and the company has submitted the data to the Food and Drug Administration and European Medicines Agency for an additional indication of adults with obesity (BMI ≥30) or who are overweight (BMI ≥27) and who have at least one weight-related comorbidity, as an adjunct to a reduced-calorie diet and increased physical activity, with a decision expected soon.

Novo Nordisk has also developed an oral form of semaglutide, which has been approved as a once-daily agent for type 2 diabetes (Rybelsus) in doses of 7 mg and 14 mg to improve glycemic control along with diet and exercise. It is the first GLP-1 agonist available in tablet form.
 

Patients lost fat mass as well as excess weight

The Brazilian study involved 58 patients with obesity or overweight who also had diabetes and were undergoing minimally invasive ESG; they were further randomized to receive semaglutide or placebo.

The GLP-1 agonist (or sham placebo) was initiated 1 month after participants had undergone the procedure and patients were monitored each month for weight loss and type of fat loss achieved with the combination versus ESG alone. The initial dose of semaglutide used was 0.25 mg subcutaneous a week but could be titrated up to a maximum dose of 1.5 mg.

At the end of 11 months of active treatment versus placebo (12 months after ESG), patients who received additional semaglutide lost 86.3% of their excess body weight – the amount of weight patients needed to lose to reach normal BMI – compared with only 60.4% for ESG controls.

Specifically, the mean percentage total body weight loss at the end of 12 months was 25.2% for those in the combination group, compared with 18.6% for those treated with ESG alone (P < .001).

More importantly, patients in the combination group lost 12.6% of their body fat mass, compared with 9% for ESG controls, while mean A1c levels fell more in those treated with additional semaglutide compared with controls (P = .0394).

Indeed, five patients in the combination group reverted to a nondiabetic state and were able to discontinue antidiabetic medications altogether, Dr. Hoff noted.

“Our main goal is not just to lose weight but to lose body mass fat, which is very different from just losing weight,” she explained.

If patients lose weight but still maintain a high percentage of body fat mass, they have what she refers to as “sarcopenic obesity” because in this state patients have lost a lot of muscle mass but still have high levels of metabolically active visceral fat. Among many other inflammatory complexes, metabolically active visceral fat contains a large number of inflammasomes, and it is the latter that have been associated with obesity-related cancers. 

“Obesity is a progressive disease, so what we are trying to do here is buy time for patients so they do not progress to [bariatric] surgery, and this approach gives patients a chance to act earlier before obesity takes over and more metabolic consequences occur,” Dr. Hoff emphasized.

So, when combined with semaglutide, “we now have a minimally invasive procedure that can be just as successful [as surgery] and which can be made available to even more people looking to lose a significant amount of weight,” she concluded.

Dr. Hoff and Dr. Kahan have reported no relevant financial relationships.

The U.S. Food and Drug Administration has granted breakthrough therapy designation for Boehringer Ingelheim’s experimental agent for the treatment of cognitive impairment associated with schizophrenia (CIAS).

The drug, known as BI 425809, is a novel glycine transporter-1 inhibitor.

The company announced it will start the CONNEX phase 3 clinical trial program to assess the safety and efficacy of the drug for improving cognition for adults with schizophrenia.

The breakthrough therapy designation and the initiation of phase 3 testing are based on results from a phase 2 clinical trial published in The Lancet Psychiatry.

In the phase 2 trial, oral BI 425809, taken once daily, improved cognition after 12 weeks for patients with schizophrenia; doses of 10 mg and 25 mg showed the largest separation from placebo.

Impairment of cognitive function is a major burden for people with schizophrenia, and no pharmacologic treatments are currently approved for CIAS.

“Cognition is a fundamental aspect of everyday life, including problem solving, memory, and attention, which is why finding solutions for cognitive impairment is a key area of Boehringer Ingelheim mental health research,” Vikas Mohan Sharma, MS, with Boehringer Ingelheim, said in a news release.

“This breakthrough therapy designation further highlights the urgent need for novel treatments for people living with schizophrenia. By combining traditional treatment approaches with new and innovative technologies, we are developing targeted therapies that will help to ease the burden of mental health conditions and enable people living with these conditions to create more meaningful connections to their lives, loved ones, and society,” said Mr. Sharma.

The CONNEX clinical trial program is composed of three clinical trials – CONNEX-1, CONNEX-2, and CONNEX-3. All are phase 3 randomized, double-blind, placebo-controlled parallel group trials that will examine the efficacy and safety of BI 425809 taken once daily over a 26-week period for patients with schizophrenia.

The primary outcome measure is change from baseline in overall composite T-score of the Measurement and Treatment Research to Improve Cognition in Schizophrenia consensus cognitive battery.

The CONNEX trial program will use VeraSci’s Pathway electronic clinical outcome assessment platform, including VeraSci’s Virtual Reality Functional Capacity Assessment Tool (VRFCAT), which simulates key instrumental activities of daily living in a realistic interactive virtual environment, VeraSci explains in a news release announcing the partnership with Boehringer Ingelheim.

The VRFCAT is sensitive to functional capacity deficits and has been accepted into the FDA’s Clinical Outcome Assessment Qualification Program.

The CONNEX trials will also utilize speech biomarker technology from Aural Analytics, which will provide a “richer picture of trial participants’ cognition alongside more conventional clinical outcome measures,” Boehringer Ingelheim says.

“Several of the symptoms of schizophrenia are generated by cognitive and emotional processes that can be identified through disruptions in the outward flow of speech. Using innovative speech analytics may help to objectively assess the downstream consequences of these disruptions,” said Daniel Jones, Aural Analytics co-founder and CEO.

The U.S. Food and Drug Administration has granted breakthrough therapy designation for Boehringer Ingelheim’s experimental agent for the treatment of cognitive impairment associated with schizophrenia (CIAS).

The drug, known as BI 425809, is a novel glycine transporter-1 inhibitor.

The company announced it will start the CONNEX phase 3 clinical trial program to assess the safety and efficacy of the drug for improving cognition for adults with schizophrenia.

The breakthrough therapy designation and the initiation of phase 3 testing are based on results from a phase 2 clinical trial published in The Lancet Psychiatry.

In the phase 2 trial, oral BI 425809, taken once daily, improved cognition after 12 weeks for patients with schizophrenia; doses of 10 mg and 25 mg showed the largest separation from placebo.

Overuse of basal insulin rather than adding therapies that target mealtime glucose levels is a common problem in primary care management of type 2 diabetes that impedes achievement of optimal glycemic control, new research suggests.

Such ‘overbasalization,’ defined as a hemoglobin A1c of greater than 8% despite use of more than 0.5 units/kg per day of basal insulin, was identified in about 40% of patients seen in a Florida primary care clinic during 2015-2018. The findings were published in the April 2021 issue of Clinical Diabetes by Kevin Cowart, PharmD, a diabetes care and education specialist at the University of South Florida, Tampa, and colleagues.

The literature suggests that once people with type 2 diabetes start basal insulin, the chance that they’ll achieve a given hemoglobin A1c target, i.e., less than 7%, diminishes significantly if that goal isn’t achieved within the first year of starting insulin, Dr. Cowart said in an interview.

“Our analysis suggests that overbasalization plays a role in patients with type 2 diabetes on basal insulin not achieving optimal glycemic control. Basal insulin is not designed to address postprandial hyperglycemia. I think there’s a clear need to address hesitancy in therapeutic progression beyond basal insulin. A lot of factors underlie the delays, with therapeutic inertia being one of them. It’s complex,” he said.
 

Overbasalization seen in large proportion of patients

The study comprised 655 adults diagnosed with type 2 diabetes for at least a year who received a prescription for a basal insulin (glargine U-100, glargine U-300, detemir, degludec U-100, degludec U-200, regular U-500, or NPH insulin).

The patients had a mean hemoglobin A1c of 8.4% and a mean basal insulin dose 0.4 units/kg per day. The prevalence of overbasalization was 38.1% for those with hemoglobin A1c above 8%, 42.7% for those with A1c of 9% or above, and 42% with A1c of 10% or greater.

Patient characteristics independently associated with overbasalization were age 35-54 years (odds ratio 1.89), age 65-80 years (0.44), A1c 9% or greater (13.97), and A1c 10% or greater (6.04). Having a prescription for insulin glargine U-100 was associated with a lower overbasalization risk (0.62). In multivariate analysis, only an A1c of 9% or greater remained significant.

Rozalina G. McCoy, MD, an endocrinologist and primary care clinician at the Mayo Clinic, Rochester, Minn., said in an interview that she sees [overbasalization] frequently in patients who are referred to her. “It’s kind of that wall that patients with type 2 diabetes hit because their A1c is high but their fasting blood sugars are normal. Sometimes it’s assumed that there’s a discrepancy, because people don’t always think about postprandial hyperglycemia.”

She also noted that there has been a push in recent years to simplify regimens, particularly in older patients.

“We really want to avoid rapid-acting insulin in older patients because we’re afraid of hypoglycemia, so we start them on basal and keep the noninsulins like metformin and sulfonylureas around. Initially those control the postprandial blood sugar but over time they’re no longer enough.”
 

Options exist for addressing postmeal blood sugar highs while minimizing lows

While in the past adding premeal insulin was the only option, today there are alternatives for addressing postmeal hyperglycemia, at least in the short term.

Dr. Cowart advised that the first step is to have patients self-monitor their blood glucose and titrate their basal insulin to address fasting hyperglycemia first. Once that appropriate dose is reached, if the patient’s hemoglobin A1c is still above target, the next step is to evaluate the need for postmeal control.

For patients who are at high cardiovascular risk, the next step might involve adding a sodium-glucose cotransporter 2 inhibitor (SGLT2i) or a glucagon-like peptide 1 receptor agonist (GLP-1RA) instead of premeal insulin. But for patients in whom overbasalization is the main concern, a GLP-1RA might be the better choice since it will have a greater impact on postprandial glucose levels, while an SGLT2i will have more effect on fasting blood sugar, he said.

Another option is to use a fixed-dose combination of basal insulin and a glucagon-like peptide 1 receptor agonist (GLP-1RA), provided there aren’t cost or formulary barriers. “We want to use the right combination of drugs and not use too much of one to lead to hypoglycemia,” Dr. Cowart said.

Dr. McCoy doesn’t use fixed-dose combinations because they don’t allow as much flexibility in dosing. To correct overbasalization, she also recommends adding either a GLP-1RA or SGLT2i instead of premeal insulin. However, she cautions, “you still have to monitor those patients because after a few years it still won’t be enough and you’ll have to add mealtime insulin.”

If cost or lack of coverage prevents a patient’s use of SLGT2i/GLP-1RAs, Dr. McCoy said that adding just one premeal injection of rapid-acting insulin before the largest meal of the day is one option. Another is to use twice-daily NPH insulin instead of analog basal insulin, since that does offer some postprandial coverage.

Dr. Cowart said his approach in cost barrier situations is to try to use patient assistance programs and to look into the patient’s formulary to see if there is step therapy or tier considerations, and maybe have a discussion with the insurance company. “We often have to navigate that, and it does take a significant amount of time and could potentially delay patients getting the right therapy when it’s warranted. That is an area where there is a particular role for pharmacists in helping to overcome that and get patients on the right drugs,” he explained.
 

Problem may be even more common; testing is key

Dr. McCoy said that the A1c cutoff of 8% used to define overbasalization in the study probably resulted in an underestimation of the problem, since many patients are experiencing nighttime hypoglycemia from the basal insulin. The lows bring down their A1c level, but they’re still experiencing postmeal highs.

“I think they’re missing a lot of people, to be honest. I see a lot of patients with A1cs that aren’t that bad, say 7.5%, and their fasting blood sugars are okay, but if you were to put a [continuous glucose monitor] on those patients, invariably there’s hypoglycemia at night that no one knew about.”

Of course, for insurance reasons, most people with type 2 diabetes don’t currently have access to continuous glucose monitors. And often those who are not taking multiple daily injections are limited to one fingerstick test strip a day.

Dr. McCoy says that if hypoglycemia is a concern she will write a prior authorization justifying more test strips.

“I state explicitly in my notes why I recommend frequent monitoring. If they’re on a sulfonylurea, they should be able to check more frequently because they can have hypoglycemia. Same thing with basal insulin.”

Dr. McCoy advises that patients test their blood sugar 2 hours after the largest meal on one day, and at other times on different days. “Blood glucose after a meal shouldn’t be more than 200 [mg/dL]. If it is, that’s not a failure of basal insulin. It’s doing its job. You just need a different agent.”

After patients with peripheral artery disease undergo lower-extremity revascularization, they are at high risk for major adverse limb events, and new findings from a prespecified analysis of data from the VOYAGER-PAD trial show that treatment with the direct-acting oral anticoagulant rivaroxaban along with aspirin significantly cut the rate of total major adverse limb events in these patients.

These findings confirm the drop in first major adverse limb events linked to rivaroxaban treatment that was VOYAGER-PAD’s primary result, reported just over a year ago.

The new total-event analysis also provides important insight into the huge magnitude of total major adverse limb events that patients with PAD can develop following lower-extremity revascularization (LER).

The 6,564 patients who all received aspirin and were randomized to either rivaroxaban (Xarelto) or placebo had 4,714 total events during a median follow-up of 2.5 years following their revascularization procedure. This included 1,092 first primary events (a composite of acute limb ischemia, major amputation for vascular causes, MI, ischemic stroke, or cardiovascular death), 522 primary events that occurred as second or subsequent events among patients after a first primary event (a nearly 50% increase from first events only), and 3,100 additional vascular events that did not fit into the primary-event category, most often a peripheral revascularization procedure, Rupert M. Bauersachs, MD, said at the annual scientific sessions of the American College of Cardiology.

“We were all astonished by this high event rate,” Dr. Bauersachs said during his report.

The total-event analysis that he reported showed that treatment with rivaroxaban resulted in a significant 14% relative reduction, compared with placebo in the incidence of total primary events, which closely tracks the significant 15% relative reduction in first primary events reported from the VOYAGER-PAD trial in 2020. Treatment with rivaroxaban also significantly linked with a 14% cut in total vascular events, compared with placebo, including the many events not included in the primary endpoint, said Dr. Bauersachs, who until his retirement in May 2021 was director of the Clinic for Vascular Medicine at the Darmstadt (Germany) Clinic. Concurrently with the report, the results appeared online.

“If one focuses only on first events, you miss the totality of disease burden. There is even greater benefit by reducing total events,” Dr. Bauersachs said during a press briefing. Adding rivaroxaban prevented roughly 2.6 first primary events for every 100 patients treated, but it also prevented 4.4 total primary events and 12.5 total vascular events for every 100 treated patients.

An ‘incredibly high’ event rate

“I don’t think any of us imagined the level of morbidity in this population. The event rate is incredibly high,” commented Joshua A. Beckman, MD, professor and director of vascular medicine at Vanderbilt University Medical Center, Nashville, Tenn.

Because treatment with rivaroxaban showed clear efficacy for also preventing subsequent events it should not be considered to have failed in patients who have a vascular event while on rivaroxaban treatment, he added as designated discussant for the report. Treatment with rivaroxaban “should be continued indefinitely,” he concluded.

“It’s quite astonishing to see the magnitude of [total] events in these patients,” commented Sahil A. Parikh, MD, a cardiologist and director of endovascular services at Columbia University Medical Center in New York. “We’ve always known that these are high-risk patients, but exactly how high their risk is was not well understood until these data came to light.”

Dr. Parikh also noted that, despite the clear evidence reported from VOYAGER-PAD more than a year ago proving the efficacy and safety of adding rivaroxaban to aspirin for long-term treatment of patients with PAD following LER, this regimen has not yet become standard U.S. practice.
 

Rivaroxaban use falls short of the expected level

“This paradigm shift has not seen the level of adoption that we would expect based on the data,” he said. “There have been numerous editorials and discussions of this at every major medical meeting” during the past year, but those expert opinions have not translated into changed practice. “Perhaps the pandemic has muted enthusiasm for adoption of a new therapeutic paradigm,” suggested Dr. Parikh, and “on top of that guidelines have yet to be updated,” although he noted that updated guidelines from the ACC and American Heart Association for PAD that include the types of patients enrolled in VOYAGER-PAD are now under review and should be released by the first half of 2022.

“I think the additional data [reported by Dr. Bauersachs] will encourage us to use rivaroxaban in patients with claudication,” Dr. Parikh said. “Perhaps we should use rivaroxaban and aspirin in a broader swath of patients, but it will take time to convince some constituencies.”

VOYAGER-PAD randomized patients with PAD who underwent successful LER within 10 days prior to enrollment at 542 sites in 34 countries during 2015-2018. In addition to every patient receiving 100 mg aspirin daily and either 2.5 mg rivaroxaban twice daily or placebo once daily, patients who received an intra-arterial device such as a stent could also receive the antiplatelet agent clopidogrel for a planned maximum of 30 days after revascularization at the discretion of their physician, and the trial protocol allowed for extending clopidogrel treatment to as many as 60 days.

In addition to the efficacy outcomes, the safety results showed that adding rivaroxaban to aspirin appeared to increase bleeding episodes, but at rates that generally did not reach significance and that were dwarfed by the efficacy benefit. The study’s primary safety outcome was the incidence of Thrombolysis in Myocardial Infarction (TIMI) major bleeding episodes, which occurred in 2.65% of patients who received rivaroxaban and in 1.87% on those on placebo, a 43% relative increase that fell short of significance (P = .07). The analyses overall indicated that 10,000 similar patients treated for 1 year with rivaroxaban would have 181 fewer primary events, compared with placebo-treated patients at the cost of also having 29 additional TIMI major bleeding events compared with patient on placebo.

Adding clopidogrel adds little except bleeding

Further analysis showed that just over half of enrolled patients also received clopidogrel for a median of 29 days following their LER procedure. This added agent produced no significant added benefit during 3-year follow-up, but did boost bleeding risk, especially in patients who received clopidogrel for more than 30 days. This led the study investigators to suggest that, while rivaroxaban plus aspirin is indicated for long-term treatment, addition of clopidogrel on top of this should be limited to 30 days or fewer to minimize bleeding risk.

“I’m sure there is a bleeding hazard associated with rivaroxaban plus aspirin, but this is attenuated by using dual therapy and not using triple therapy” by also adding clopidogrel, noted Dr. Parikh.

The new VOYAGER-PAD results also showed that the ongoing risk faced by patients with PAD following LER applies globally to their peripheral arteries. Of the 3,034 total peripheral revascularizations performed in the cohort during follow-up, 64% occurred in the index limb and 36% in the contralateral limb. Another striking finding was that the need for ipsilateral repeat revascularization was more common after an index endovascular procedure, 2,329 repeat revascularizations in 4,379 of these patients (53%), compared with 2,185 patients who had surgical revascularization for their index procedure and subsequently 705 of these patients (32%) needed repeat revascularization.

But rivaroxaban treatment appeared to provide little benefit for the much less frequent incidence of first and subsequent events in the coronary and cerebral circulation. During follow-up, the rates of major adverse cardiovascular events – cardiovascular death, nonfatal MI, and nonfatal stroke – were virtually identical in the rivaroxaban and placebo groups.

“This study makes it clear that we are learning about differences in presentation between the vascular beds, and the benefits of specific treatments in each vascular bed,” Dr. Beckman said.

VOYAGER-PAD was sponsored by Bayer and Janssen, the companies that market rivaroxaban (Xarelto). Dr. Bauersachs has received personal fees from Bayer, as well as from Bristol-Myers Squibb, Daiichi Sankyo, and Pfizer, and has received grant support from Aspen Pharma.

After patients with peripheral artery disease undergo lower-extremity revascularization, they are at high risk for major adverse limb events, and new findings from a prespecified analysis of data from the VOYAGER-PAD trial show that treatment with the direct-acting oral anticoagulant rivaroxaban along with aspirin significantly cut the rate of total major adverse limb events in these patients.

These findings confirm the drop in first major adverse limb events linked to rivaroxaban treatment that was VOYAGER-PAD’s primary result, reported just over a year ago.

The new total-event analysis also provides important insight into the huge magnitude of total major adverse limb events that patients with PAD can develop following lower-extremity revascularization (LER).

The 6,564 patients who all received aspirin and were randomized to either rivaroxaban (Xarelto) or placebo had 4,714 total events during a median follow-up of 2.5 years following their revascularization procedure. This included 1,092 first primary events (a composite of acute limb ischemia, major amputation for vascular causes, MI, ischemic stroke, or cardiovascular death), 522 primary events that occurred as second or subsequent events among patients after a first primary event (a nearly 50% increase from first events only), and 3,100 additional vascular events that did not fit into the primary-event category, most often a peripheral revascularization procedure, Rupert M. Bauersachs, MD, said at the annual scientific sessions of the American College of Cardiology.

“We were all astonished by this high event rate,” Dr. Bauersachs said during his report.

The total-event analysis that he reported showed that treatment with rivaroxaban resulted in a significant 14% relative reduction, compared with placebo in the incidence of total primary events, which closely tracks the significant 15% relative reduction in first primary events reported from the VOYAGER-PAD trial in 2020. Treatment with rivaroxaban also significantly linked with a 14% cut in total vascular events, compared with placebo, including the many events not included in the primary endpoint, said Dr. Bauersachs, who until his retirement in May 2021 was director of the Clinic for Vascular Medicine at the Darmstadt (Germany) Clinic. Concurrently with the report, the results appeared online.

“If one focuses only on first events, you miss the totality of disease burden. There is even greater benefit by reducing total events,” Dr. Bauersachs said during a press briefing. Adding rivaroxaban prevented roughly 2.6 first primary events for every 100 patients treated, but it also prevented 4.4 total primary events and 12.5 total vascular events for every 100 treated patients.

An ‘incredibly high’ event rate

“I don’t think any of us imagined the level of morbidity in this population. The event rate is incredibly high,” commented Joshua A. Beckman, MD, professor and director of vascular medicine at Vanderbilt University Medical Center, Nashville, Tenn.

Because treatment with rivaroxaban showed clear efficacy for also preventing subsequent events it should not be considered to have failed in patients who have a vascular event while on rivaroxaban treatment, he added as designated discussant for the report. Treatment with rivaroxaban “should be continued indefinitely,” he concluded.

“It’s quite astonishing to see the magnitude of [total] events in these patients,” commented Sahil A. Parikh, MD, a cardiologist and director of endovascular services at Columbia University Medical Center in New York. “We’ve always known that these are high-risk patients, but exactly how high their risk is was not well understood until these data came to light.”

Results from the NAVIGATOR study of tezepelumab showed that treatment of adults and adolescents with severe, uncontrolled asthma with the new biologic led to a large reduction in exacerbations requiring hospital stays and ED visits.

Tezepelumab, codeveloped by Amgen and AstraZeneca, has a novel mechanism of action. It blocks thymic stromal lymphopoietin (TSLP), which is a cytokine produced by epithelial cells. TSLP levels correlate with airway obstruction, severity of disease, and glucocorticoid resistance. TSLP is involved in T2 inflammation within the airway, but also plays a role in the interactions between airway cells and immune cells, which doesn’t rely only solely on T2 inflammation. That broad mechanism of action distinguishes tezepelumab from most other biologics for the treatment of asthma, which are more targeted.

“By working at the top of the cascade, tezepelumab helps stop inflammation at a key source. Clinical trials with tezepelumab showed a clinical benefit in patients irrespective of their baseline biomarker level, including patients with low eosinophil levels at baseline,” said Jean-Pierre Llanos-Ackert, MD, who is executive medical director and global medical affairs lead for tezepelumab at Amgen.

The primary endpoint data look robust, according to Praveen Akuthota, MD, who is an associate professor of medicine at the University of California, San Diego, and comoderated the session at the American Thoracic Society’s virtual international conference, where the research was presented. The study was also published on May 13, 2021, in the New England Journal of Medicine. The conference session included updated results.

The drug holds promise, but more study is needed. “The question really will be, how is this drug different from the existing biologics? How much better is this drug in patients who have borderline T2 biomarkers, or even low T2. The study does show some efficacy in patients whose T2 signals may not be as robust. We’ll have to see with ongoing longitudinal data, how this drug positions, compared to the other agents. It’s obviously exciting, though, to have another option, given that we know what our current armamentarium of agents there are still nonresponders,” said Dr. Akuthota in an interview.

The other comoderator in the session, Laura Crotty Alexander, MD, commented: “It seems like it might work possibly even better than some that are directly covering one pathway only. Hopefully, this agent will be efficacious in a broader population than some of the more targeted biologics.” Dr. Alexander is an associate professor of medicine at the University of California, San Diego, and section chief of pulmonary critical care at the Veterans Affairs San Diego Healthcare System.

She pointed out that physicians often think of asthma patients in broad brush terms, as high or low T2, or T2 high and Th1 or neutrophilic or obese, but many patients present a more complicated picture. “There is some overlap across those phenotypes, such that an agent that works really well for one group doesn’t mean that it won’t have an impact, especially clinically, on some of these other phenotypes,” said Dr. Alexander.

Dr. Akuthota agreed. “Having options for patients whose biomarkers are not maybe as clear is, I think, important.”
 

Promising results

The study included 1,059 patients aged 12-80 who received 210 mg tezepelumab or placebo. Over 52 weeks, the treatment group had a 79% reduction in exacerbations requiring hospitalization or an ED visit, compared with placebo (rate ratio, 0.21; 95% confidence interval, 0.12-0.37), and an 85% reduction in exacerbations requiring hospitalization (RR, 0.15; 95% CI, 0.07-0.33). The drug increased the time to first exacerbation requiring hospitalization that required hospitalization or an ED visit, reducing risk by 65% (hazard ratio, 0.35; 95% CI, 0.22-0.56).

Fewer patients in the treatment group than placebo used asthma-related health care resources, including: ED visits (32 vs. 94), unscheduled visit to a specialist (285 vs. 406), telephone calls to a health care provider (234 vs. 599), ambulance transport (5 vs. 22), and home visits from a health care provider (18 vs. 22). Fewer patients in the tezepelumab group had hospital stays (3.2% vs. 7.0%), and they had a lower total number of hospital days (108 vs. 497) and days in the ICU (0 vs. 31).

The study was funded by Amgen and AstraZeneca. Dr. Llanos-Ackert is an employee of Amgen. Dr. Alexander has no relevant financial disclosures. Dr. Akuthota has consulted for AstraZeneca and participated in their clinical trials.

How much better is this drug in patients who have borderline T2 biomarkers, or even low T2. The study does show some efficacy in patients whose T2 signals may not be as robust. We’ll have to see with ongoing longitudinal data, how this drug positions, compared to the other agents. It’s obviously exciting, though, to have another option, given that we know what our current armamentarium of agents there are still nonresponders,” said Dr. Akuthota in an interview.

The other comoderator in the session, Laura Crotty Alexander, MD, commented: “It seems like it might work possibly even better than some that are directly covering one pathway only. Hopefully, this agent will be efficacious in a broader population than some of the more targeted biologics.” Dr. Alexander is an associate professor of medicine at the University of California, San Diego, and section chief of pulmonary critical care at the Veterans Affairs San Diego Healthcare System.

She pointed out that physicians often think of asthma patients in broad brush terms, as high or low T2, or T2 high and Th1 or neutrophilic or obese, but many patients present a more complicated picture. “There is some overlap across those phenotypes, such that an agent that works really well for one group doesn’t mean that it won’t have an impact, especially clinically, on some of these other phenotypes,” said Dr. Alexander.

Dr. Akuthota agreed. “Having options for patients whose biomarkers are not maybe as clear is, I think, important.”
 

Promising results

The study included 1,059 patients aged 12-80 who received 210 mg tezepelumab or placebo. Over 52 weeks, the treatment group had a 79% reduction in exacerbations requiring hospitalization or an ED visit, compared with placebo (rate ratio, 0.21; 95% confidence interval, 0.12-0.37), and an 85% reduction in exacerbations requiring hospitalization (RR, 0.15; 95% CI, 0.07-0.33). The drug increased the time to first exacerbation requiring hospitalization that required hospitalization or an ED visit, reducing risk by 65% (hazard ratio, 0.35; 95% CI, 0.22-0.56).

Fewer patients in the treatment group than placebo used asthma-related health care resources, including: ED visits (32 vs. 94), unscheduled visit to a specialist (285 vs. 406), telephone calls to a health care provider (234 vs. 599), ambulance transport (5 vs. 22), and home visits from a health care provider (18 vs. 22). Fewer patients in the tezepelumab group had hospital stays (3.2% vs. 7.0%), and they had a lower total number of hospital days (108 vs. 497) and days in the ICU (0 vs. 31).

The study was funded by Amgen and AstraZeneca. Dr. Llanos-Ackert is an employee of Amgen. Dr. Alexander has no relevant financial disclosures. Dr. Akuthota has consulted for AstraZeneca and participated in their clinical trials.

The Food and Drug Administration has approved the adjuvant use of nivolumab (Opdivo) in patients with resected esophageal or gastroesophageal junction (GEJ) cancer who have received neoadjuvant chemoradiotherapy and have residual pathological disease following surgery.

The approval addresses an unmet need among these patients, who have a high risk of recurrence but for whom surveillance is the only current management option after the above-described standard treatment, according to experts.

The FDA’s approval is based on results from the CheckMate 577 study, which showed a significant improvement in disease-free survival compared with placebo.

This was described as “a practice-changing trial in the treatment of esophageal cancer” by David H. Ilson, MD, PhD, Memorial Sloan Kettering Cancer Center, New York, in an editorial in The New England Journal of Medicine that accompanied the published study results.

“The trial shows the first true advance in the adjuvant therapy of esophageal cancer in recent years,” wrote Dr. Ilson.

In the randomized, double-blind, phase 3 trial, patients with resected stage II or III esophageal or GEJ cancer were randomly assigned in a 2:1 ratio to receive nivolumab (at a dose of 240 mg every 2 weeks for 16 weeks, followed by a dose of 480 mg every 4 weeks) or placebo. The maximum duration of the intervention period was 1 year.

All of these patients had received neoadjuvant chemoradiotherapy and had residual pathological disease, as noted in the new indication. Patients were enrolled regardless of programmed death ligand 1 (PD-L1) expression.

For the primary endpoint of disease-free survival, the median was 22.4 months for the nivolumab group (n = 532) versus 11.0 months for the placebo group (n = 262; hazard ratio [HR] for disease recurrence or death, 0.69; 96.4% confidence interval [CI], 0.56-0.86; P < .001).

The median follow-up was 24.4 months.

Disease-free survival favored nivolumab across multiple preplanned subgroups.

However, as Dr. Ilson noted in the editorial, the efficacy of nivolumab varied, with more benefit seen for patients with squamous cell cancer (HR, 0.61) than for those with adenocarcinoma (HR, 0.75). Patients with esophageal tumors also had greater benefit (HR, 0.61) than did those with GEJ tumors (HR, 0.87).

There was benefit in patients with node-negative disease (HR, 0.74) and node-positive disease (HR, 0.67) and benefit in patients with tumors that were PD-L1–negative (HR, 0.73) and PD-L1–positive (HR, 0.75).

There were fewer distant recurrences in the nivolumab group than in the placebo group (29% vs. 39%) and fewer locoregional recurrences (12% vs. 17%).

No new safety signals were observed, and 9% of the nivolumab patients discontinued the drug because of treatment-related adverse events versus 3% of placebo patients. In addition, a 1-year course of adjuvant nivolumab did not negatively impact patient-reported quality of life, the trialists reported.

Grade 3 or 4 adverse events of any cause were more frequent in the nivolumab group versus the placebo group (34% vs. 32%) as were those related to the intervention (13% vs. 6%).

Although overall survival data are not mature, “the doubling of median disease-free survival will almost certainly translate into an overall survival benefit,” Dr. Ilson wrote.

Notably, the trial’s original co-primary endpoint was overall survival, but was dropped to a secondary endpoint after enrollment “challenges.”

When the now-published data were first presented at the 2020 annual meeting of the European Society for Medical Oncology, the invited discussant, Andrés Cervantes, MD, PhD, University of Valencia, Spain, raised several issues with the trial.

Preoperative chemoradiation is not “universally accepted” as the standard of care in this setting, said Dr. Cervantes, president-elect of ESMO.

Dr. Ilson acknowledged as much. “A debate is ongoing about whether chemotherapy alone or combined chemoradiotherapy is the preferred treatment for esophageal cancer before surgery,” he wrote.

In addition, Dr. Cervantes noted that disease-free survival is not currently validated as a major endpoint in gastroesophageal cancers, and the median follow-up was short.

The greatest relative benefit from omecamtiv mecarbil, a member of the novel myotropic drug class that improves cardiac performance, is produced in heart failure patients with the lowest left ventricular ejection fraction (LVEF), a new analysis of the recently published phase 3 GALACTIC-HF trial has found.

The findings reinforce the potential for this drug to be helpful in the management of the most advanced stages of heart failure with reduced ejection fraction (HFrEF), reported John R. Teerlink, MD, director of heart failure at San Francisco Veterans Affairs Medical Center, at the annual scientific sessions of the American College of Cardiology.

The phase 3 multinational GALACTIC-HF trial, published earlier this year, linked omecamtiv mecarbil with an 8% reduction in the risk of a heart failure–related events or cardiovascular death, relative to placebo, which was the primary outcome. For entry, HFrEF patients were required to have a LVEF of 35% or less.

Drilling down on ejection fraction

The new analysis divided participants into quartiles of baseline LVEF and then compared relative outcomes and safety.

In the lowest quartile, defined by a LVEF of 22% or lower, the reduction in risk of events reached 17% (hazard ratio, 0.83; 95% confidence interval, 0.73-0.95) for omecamtiv mecarbil relative to placebo. In the highest, defined by a LVEF of 33% or greater, the benefit fell short of significance (HR 0.99; 95% CI, 0.84-1.16). Across quartiles, LVEF was the “strongest modifier of the treatment effect,” emerging in this analysis as a statistically significant (P = .004) continuous variable.

The comparison by LVEF quartiles also provided an opportunity to show that omecamtiv mecarbil was as safe and well tolerated in those with the most advanced disease as in those less sick. At the lowest levels of LVEF, like the higher levels, omecamtiv mecarbil did not produce any adverse effects on blood pressure, heart rate, potassium homeostasis, or renal function.

In GALACTIC-HF, 8,256 HFrEF patients with LVEF 35% or less were randomized to omecamtiv mecarbil or placebo. The primary composite outcome of hospitalization or urgent visit for heart failure or death from cardiovascular causes was evaluated after a median of 21.8 months on therapy.

When incidence rate per 100 patient years was graphed against the range of LVEF, the relative advantage of omecamtiv mecarbil became visible just below an LVEF of 30%, climbing steadily even to the lowest LVEF, which reached 10%.

Perhaps relevant to the reduction in events, there were also greater relative reductions in NT-proBNP (NT-proB-type natriuretic peptide) for omecamtiv mecarbil at lower relative to higher LVEF. Although omecamtiv mecarbil is not associated with any direct vascular, electrophysiologic, or neurohormonal effects, according to Dr. Teerlink, the indirect effects of selective binding to cardiac myosin has been associated with lower NT-proBNP and other biomarkers of cardiac remodeling in prior clinical studies.

Although Dr. Teerlink acknowledged that relatively few patients in GALACTIC-HF received an angiotensin-receptor neprilysin inhibitor (ARNI) or a sodium glucose cotransporter-2 (SGLT2) inhibitor, he said there is “every reason to believe that omecamtiv mecarbil would be complementary to these therapies.” He said the mechanism of action of omecamtiv mecarbil, which improves systolic function, has no overlap with these drugs.

Importantly, there is a particular need for new treatment options in patients with advanced LVEF, according to Dr. Teerlink, who cited evidence, for example, that “the beneficial effect of [the ARNI] sacubitril valsartan, while still significant, decreases in patients with LVEF less than 35%.”

Overall, based on these results, “we believe that omecamtiv mecarbil represents a novel therapy that holds the promise of improving clinical outcomes in patients with severely reduced ejection fraction, which are the very patients that are most challenging for us to treat,” Dr. Teerlink said.
 

Omecamtiv mecarbil may ‘buy you some time’

Ileana Piña, MD, clinical professor of medicine, Central Michigan University, Mount Pleasant, Mich., agreed. She said that omecamtiv mecarbil, if approved, will be an option for the type of HFrEF patients who are being considered for heart transplant or mechanical-assist devices.

“We are very loath to use inotropes in this population, because we know that ultimately the inotrope is not going to do well,” said Dr. Piña, calling these therapies a “Band-Aid.” Based on the evidence from GALACTIC-HF, she thinks that omecamtiv mecarbil will be more versatile.

“This drug does not increase myocardial oxygen demand as do the inotropes, and it can be given in the outpatient setting if need be, so I see this as a real advance,” Dr. Piña said. Although Dr. Piña acknowledged that omecamtiv mecarbil did not reduce mortality in the GALACTIC-HF trial, “at least it will buy you some time.”

Dr. Teerlink has financial relationships with multiple pharmaceutical companies, including Amgen, Cytogenetics, and Servier, which provided funding for the GALACTIC-HF trial. Dr. Piña reports no potential conflicts of interest.
