FDA Approves Diabetes Drug for Weight Loss
FDA has approved a Novo Nordisk NDA for Wegovy (semaglutide) injection (2.4 mg once weekly) for treating adults with obesity or who are overweight with at least one weight-related condition (e.g., high blood pressure, Type 2 diabetes, or high cholesterol). FDA says the subcutaneous injection is the first approved drug for chronic weight management since 2014.
The drug is indicated for chronic weight management in patients with a body mass index of 27 kg/m2. It is intended for use in addition to a reduced calorie diet and increased physical activity. Semaglutide 1 mg injection (Ozempic) was originally approved as a treatment for Type 2 diabetes in 2017.
Wegovy works by mimicking the hormone called glucagon-like peptide-1 (GLP-1) that targets areas of the brain that regulate appetite and food intake. “The medication dose must be increased gradually over 16 to 20 weeks to 2.4 mg once weekly to reduce gastrointestinal side effects,” the agency says.
Approval was based on data from two clinical trials. In one trial involving patients without diabetes, FDA says the average body weight of participants was 231 pounds and individuals who received Wegovy lost an average of 12.4% of their initial body weight compared to individuals who received placebo. Another trial enrolled adults with Type 2 diabetes with an average body weight of 220 pounds, and these individuals lost 6.2% of their initial body weight compared to those who received placebo.
