In a sea of uncertainty, a large-scale, long-term Swedish study is the first to show that people using GLP-1 receptor agonists are less likely to have worsening mental illness. The study involved a national cohort of 95,490 people diagnosed with depression or anxiety disorder, who also were treated with any diabetes drug (apart from insulin).

A new study has reinforced that GLP-1 receptor agonists are unlikely to produce durable weight loss, but indicates that rather than returning to the starting weight, individual weight gain will plateau at 75.5% of the weight lost.

There are two significant messages for companies developing and profiting from obesity drugs in a meta-analysis of clinical trials examining the extent of weight regain after treatment stops. First, people taking obesity medication regain weight four times faster on average than those who lose weight through behavioral diet and exercise programs; and second, poor tolerability leads to poor adherence.

The U.S. FDA has approved its first pharma treatment in more than 40 years for motion sickness. The green light for Nereus (tradipitant), from Vanda Pharmaceuticals Inc., was based on three clinical studies, all pivotal, including two phase III real-world trials with patients on boats and another supporting study.

The U.S. Centers for Medicare & Medicaid Services (CMS) rolled out negotiated costs of the second batch of drugs subject to such bargaining under the Inflation Reduction Act. Wall Street was not surprised to learn that the numbers amount to much greater cuts than the Biden administration managed for 2026. CMS said the adjusted maximum fair prices would have achieved 44% lower net spending had they been implemented in 2024 – 36% if forgiven discounts from the part D redesign of the Medicare prescription drug benefit are figured in. Fifteen drugs are listed.

Hailing it as a win-win and a historic step forward in fighting chronic disease, the Trump administration announced pricing agreements Nov. 6 with Eli Lilly and Co. and Novo Nordisk A/S that will expand the availability of the companies’ weight loss drugs by cutting prices and, for the first time, providing coverage for the drugs in obesity through Medicare and Medicaid.

Phase IIb data of Metsera Inc.’s lead GLP-1 receptor agonist, MET-097i, showed significant weight loss and good tolerability, supporting a phase III start later this year, and validating Pfizer Inc.’s decision a week ago to buy the obesity-focused company for $7.3 billion.
