Panel Rejects Lexicon Pharma Diabetes Drug
FDA’s Endocrinologic and Metabolic Drugs Advisory Committee 10/31 voted 11 to 3 against recommending approval for Lexicon Pharmaceuticals' drug Zynquista (sotagliflozin) as an adjunctive treatment to insulin for adults with Type 1 diabetes and chronic kidney disease. The committee's primary concern centered on safety, specifically the risk of diabetic ketoacidosis (DKA), a serious and often life-threatening consequence of insulin insufficiency. A previous submission sought an indication as an adjunct to insulin to improve glycemic control in adults with Type 1 diabetes, but that was denied in a 2019 complete response letter, which cited deficiencies such as data demonstrating that the addition of sotagliflozin to insulin is associated with an increased risk of DKA.
Despite obtaining approval for Zynquista in Europe in 2019, Lexicon has struggled to secure FDA approval stateside due to these ongoing safety concerns. Two subsequent dispute resolution requests were rejected by CDER based on a determination that the drug’s DKA risk outweighed its benefits.
FDA has set a 12/20 user fee review action target date for the current submission.
