FDA Approves Oral Semaglutide as First GLP-1 Pill for Weight Loss

The FDA has approved the first oral glucagon-like peptide-1 (GLP-1) receptor agonist for weight loss and to reduce the risk of major adverse cardiovascular events (MACE).¹ Novo Nordisk plans to launch the once-daily oral semaglutide (Wegovy) 25 mg in the US in early January 2026.

The approval is based on results from the OASIS clinical trials and the SELECT trial. OASIS 4 showed a mean weight loss of 13.6% at 64 weeks.² The study evaluated the efficacy and safety of once-daily oral semaglutide compared with placebo.

“The pill is here. With today's approval of the Wegovy pill, patients will have a convenient, once-daily pill that can help them lose as much weight as the original Wegovy injection,” Mike Doustdar, president and CEO of Novo Nordisk, said in a statement.¹ “As the first oral GLP-1 treatment for people living with overweight or obesity, the Wegovy pill provides patients with a new, convenient treatment option that can help patients start or continue their weight loss journey.”

Clinical Efficacy: The OASIS 4 Trial

The OASIS 4 trial enrolled 307 adults with obesity or overweight who received either oral semaglutide (n = 205) or placebo (n = 102). The coprimary end points were the percent change in body weight and a reduction of 5% or more in body at week 64.

Oral GLP-1 Competition on the Horizon

The FDA decision gives oral semaglutide an edge in a competitive weight loss market, with Eli Lilly having submitted its own oral GLP-1, orforglipron, to the FDA for review.³ Orforglipron is an investigational, non-peptide, once-daily oral GLP-1 receptor agonist that can be taken without restrictions on food or water intake.
