Safety Concerns and Withdrawal Request
In January 2020, the FDA began reviewing data from a long-term clinical trial assessing the safety of lorcaserin. The trial involved approximately 12,000 participants and aimed to evaluate cardiovascular risks associated with the drug. The results indicated an increased occurrence of cancer among users of lorcaserin compared to those receiving a placebo.
Key Findings from Clinical Trials
- Cancer Incidence: The trial revealed that 7.7% of patients taking lorcaserin were diagnosed with cancer compared to 7.1% in the placebo group.
- Types of cancers reported included pancreatic, colorectal, and lung cancers.
- Based on these findings, the FDA requested that Eisai Inc., the manufacturer of Belviq, voluntarily withdraw the drug from the market due to concerns that the risks outweigh its benefits.
Implications of Withdrawal
The withdrawal request has significant implications for patients who have been using Belviq:
- Discontinuation: Patients are advised to stop taking Belviq and discuss alternative weight-loss medications with their healthcare providers.
- Monitoring: While no special cancer screening is recommended for former users, standard screening practices should continue.
- Alternative Treatments: Patients may need to explore other options for weight management.
Regulatory Actions
Following the FDA’s request for withdrawal:
- Eisai Inc. Compliance: The manufacturer complied with the request and initiated processes to remove Belviq from pharmacy shelves.
- Patient Communication: Health professionals were instructed to inform patients about the potential risks associated with lorcaserin and discuss alternative treatments.
