What is Belviq?

Approved by the U.S. Food & Drug Administration (FDA) in 2012, Belviq (lorcaserin) was indicated for use with a low-calorie diet to aid weight loss in obese adults who suffered from weight-related health problems. The extended-release version of lorcaserin – Belviq XR – received FDA approval in 2016.

Belviq controls appetite by activating receptors in the brain that regulate serotonin, a neurotransmitter associated with feelings of satiety and satisfaction.

The FDA had actually declined to approve Belviq in 2010 because of animal studies that suggested the drug might be associated with an increased risk of tumors. But the agency was eventually persuaded that the tumors seen in those trials were specific to the animals.

While there were also concerns that Belviq might cause heart valve problems, additional data indicated such complications would not occur at the low doses at which Belviq was prescribed. But as a condition of approval, the FDA ordered Belviq’s manufacturer to conduct a post-market study to better assess locaserin’s potential to cause heart attacks and strokes.

Belviq Recall: What’s the Problem?

That five-year, 12,000-patient study did show that lorcaserin effectively helped people lose weight without increasing their risk of heart problems. However, 7.7% of trial participants who took Belviq were diagnosed with cancer, compared to just 7.1% in the placebo group. That amounted to one additional cancer  for every 470 patients treated with Belviq for one year.

“There was no apparent difference in the incidence of cancer over the initial months of treatment, but the imbalance increased with longer duration on lorcaserin,” the FDA said

While a range of cancers were seen in the study, pancreatic, colorectal. and lung cancers were reported more often in the patients who took Belviq.

The FDA ultimately concluded that the cancer risk outweighed any benefits associated with lorcaserin and  asked Esai, Inc. to conduct a Belviq recall.  Although the company disputed the agency’s interpretation of the study data, Esai did agree to voluntarily withdraw Belviq and Belviq XR from the market.

The FDA has not recommended any special cancer screenings for patients who were prescribed Belviq or Belviq XR. However, these individuals should stop taking the drugs, safely dispose of any leftover medication, and discuss alternative weight loss treatments with their doctor.
