Sanofi and Lexicon collaborate on sotagliflozin

6 November 2015  •  Author: Victoria White

Sanofi and Lexicon Pharmaceuticals have entered into a collaboration and license agreement for the development and commercialisation of sotagliflozin.


Sotagliflozin is an investigational new oral dual inhibitor of sodium-glucose cotransporters 1 and 2 (SGLT-1 and SGLT-2) which could be a potential treatment option for people with diabetes.

“This agreement with Lexicon reinforces our commitment to helping people living with diabetes,” said Pascale Witz, Executive Vice President, Sanofi, who will lead the Global Diabetes and Cardiovascular Care Business Unit in the company’s new organizational structure. “Adding sotagliflozin to our portfolio, which includes medicines at virtually every stage of the treatment pathway, highlights our focus on providing a large and diverse set of therapeutic options for people with this disease.”

Sotagliflozin is currently being studied in two Phase 3 trials in type 1 diabetes, which are expected to report top-line results during the second half of 2016. Phase 3 trials in type 2 diabetes are expected to begin in 2016. Sotagliflozin has previously shown encouraging results in exploratory (Phase 2) studies, including reduction of blood sugar (HbA1c), improvement in glycaemic variability and reduced meal-time insulin dose compared with placebo in type 1 diabetics. Phase 2 studies exploring treatment in people with type 2 diabetes, including those with renal impairment, showed lowering of blood sugar (HbA1c), weight loss and blood pressure improvements.

Sanofi obtains an exclusive worldwide license to commercialise sotagliflozin

“Lexicon firmly believes in the potential of sotagliflozin for patients living with diabetes. It has been our strategy to focus our resources on the development of sotagliflozin for type 1 diabetes and to pursue a strategic partnership with respect to type 2 diabetes only if it would strengthen stakeholder value under a fully integrated diabetes programme. We believe this arrangement with Sanofi achieves that objective,” said Lexicon President and Chief Executive Officer Lonnel Coats. “Sanofi’s patient-centric focus in diabetes, and its rich history of innovation in diabetes, make it an exceedingly attractive partner which is well positioned to unlock the full potential of sotagliflozin for patients living with diabetes. Also consistent with our strategy, Lexicon will continue to lead the development of sotagliflozin for type 1 diabetes and have rights to participate in the commercialisation of sotagliflozin for type 1 diabetes in the United States.”

Under the terms of the agreement, Lexicon will receive an upfront payment of $300 million and is eligible to receive development, regulatory and sales milestone payments of up to $1.4 billion.  Lexicon is also entitled to tiered, escalating double digit percentage royalties of net sales of sotagliflozin. Sanofi obtains an exclusive worldwide license to develop, manufacture and commercialise sotagliflozin.
