Lexicon Pharmaceuticals Announces EMA Acceptance of Marketing Authorization Application (MAA) for Sotagliflozin to Treat Adults With Type 1 Diabetes

THE WOODLANDS, Texas, March 29, 2018 -- Lexicon Pharmaceuticals, Inc. (Nasdaq:LXRX), today announced that the European Medicines Agency (EMA) has accepted the Marketing Authorization Application (MAA) filed by Lexicon’s collaborator, Sanofi, for sotagliflozin, an investigational dual SGLT1 and SGLT2 inhibitor, for use in combination with insulin therapy to improve glycemic control in adults with type 1 diabetes mellitus.

“By accepting the MAA filing, the EMA acknowledges the need for a new treatment option for people suffering from type 1 diabetes to address the debilitating effects of this disease,” said Pablo Lapuerta, M.D., executive vice president and chief medical officer. “We and our collaborator, Sanofi, plan to work closely with the EMA and Committee for Medicinal Products for Human Use (CHMP) toward the goal of bringing sotagliflozin to people living with type 1 diabetes in Europe as quickly as possible.”

“Type 1 diabetes is an escalating epidemic that affects many adults in Europe, and despite advancements in treatment, most people with type 1 diabetes still struggle to achieve their blood glucose goals,” said Thomas Danne, M.D., Head of the Diabetes Center at the Children’s Hospital on the Bult in Hannover, Germany and primary investigator for the inTandem2 clinical trial. “Sotagliflozin has a unique mode of action that, if approved, would offer adults suffering from type 1 diabetes and healthcare professionals improved glycemic management on top of insulin alone.”

Lexicon announced the submission of a New Drug Application (NDA) by Sanofi with the U.S. Food and Drug Administration (FDA) on March 26, 2018.

About Sotagliflozin

Discovered using Lexicon’s unique approach to gene science, sotagliflozin is an investigational oral dual inhibitor of two proteins responsible for glucose regulation known as sodium-glucose co-transporter types 1 and 2 (SGLT1 and SGLT2). SGLT1 is responsible for glucose absorption in the gastrointestinal tract, and SGLT2 is responsible for glucose reabsorption by the kidney.

Lexicon entered into a collaboration and license agreement with Sanofi in November 2015 under which Lexicon granted Sanofi an exclusive, worldwide (excluding Japan), royalty-bearing right and license to develop, manufacture and commercialize sotagliflozin. Lexicon is responsible for all clinical development activities relating to type 1 diabetes and has exercised an exclusive option to co-promote and have a significant role, in collaboration with Sanofi, in the commercialization of sotagliflozin for the treatment of type 1 diabetes in the U.S. Sanofi is responsible for all clinical development and commercialization of sotagliflozin for the treatment of type 2 diabetes worldwide (excluding Japan) and is solely responsible for the commercialization of sotagliflozin for the treatment of type 1 diabetes outside the U.S. (excluding Japan).
