Belviq Breast Cancer Lawsuit Overview:

  • Who: Former user of weight loss drug Belviq is suing the drug’s manufacturers and distributors Arena Pharmaceuticals and Eisai Inc.
  • Why: The plaintiff alleges the companies failed to adequately test and warn about the drug’s potential breast cancer-causing properties.
  • Where: The lawsuit is pending in Missouri federal court.

A Belviq lawsuit alleging the weight loss drug caused cancer will move forward, for the most part, under a new ruling by a Missouri federal judge. 

Claims that Arena Pharmaceuticals and Eisai Inc failed to properly warn patients that Arena’s weight loss drug Belviq was linked to breast cancer will reportedly proceed, while others were trimmed. 

Belviq Use Linked to Breast Cancer, Claims Lawsuit

The lawsuit, lodged by Missouri resident Amy Davis, alleged her breast cancer diagnosis in November 2019 was caused by her use of Belviq, which she began taking in 2017 to lose weight and for diet control. Davis says language around Belviq did not warn about breast cancer as a side effect, despite mentioning other breast side effects like shrinkage and lactation.

In a recent order, US District Judge Greg Kays allowed Davis’ negligence allegation against Arena which argued that the drug company violated a duty of care it owed to her by not testing Belviq more rigorously for its carcinogenic potential.

On the other hand, Judge Kays dismissed Davis’ “patently incorrect” design defect claims, noting that she failed to identify Arena’s role in manufacturing Belviq and conflated Arena’s and Eisai’s manufacturing roles. He also dismissed a claim of negligent misrepresentation against Eisai. 

In early 2020, the US Food and Drug Administration recommended removing Belviq from shelves due to an increased concern of cancer.
