Eli Lilly’s Zepbound: FDA’s Approval of Diabetes Drug for Obesity Treatment

The US Food and Drug Administration (FDA) recently granted approval for Eli Lilly’s tirzepatide, a drug primarily used for type 2 diabetes treatment, to be repurposed for chronic weight management under the new name Zepbound. This announcement solidifies the medication’s established off-label usage for weight loss purposes.

Clinical trials revealed Zepbound’s remarkable efficacy, demonstrating an average weight loss exceeding 20% over 72 weeks at higher doses, surpassing the performance of other existing weight loss drugs. However, potential side effects such as gastrointestinal disturbances (nausea, vomiting, constipation, and diarrhea) remain a concern, prompting the FDA to include relevant warnings in the drug’s label, cautioning against inflammation of the pancreas, gallbladder issues, low blood sugar, kidney injury, diabetic retinopathy, and suicidal behavior.

Eli Lilly priced Zepbound at $1,060 per month pre-insurance, positioning it as a more affordable alternative (20% less costly) to semaglutide, a comparable drug used for weight loss. In an effort to enhance accessibility, the company plans to offer a savings card option to eligible patients, enabling them to acquire the medication at a reduced price point.

Despite these advancements, concerns regarding the drug’s coverage under various insurance plans linger, potentially limiting patient access. Medicare and Medicaid, for instance, currently lack coverage for obesity medications, posing additional challenges for patients seeking treatment.

With this milestone, Eli Lilly highlights Zepbound as a significant addition to its pharmaceutical legacy, akin to the company’s groundbreaking contributions with insulin and Prozac. Amidst the burgeoning prevalence of obesity-related health concerns in the US, the FDA’s approval of Zepbound signifies a critical step in addressing the pressing need for effective weight management solutions.
