Sotagliflozin (LX4211) 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 diabetes patients.
It is currently being evaluated in two pivotal Phase 3 trials in type 1 diabetes. Phase 3 trials in type 2 diabetes are anticipated to start next year.
In exploratory (Phase 2) studies, sotagliflozin lowered blood sugar (HbA1c), improved glycemic variability and reduced meal-time insulin dose compared with placebo in type 1 diabetics.
Phase 2 studies in patients with type 2 diabetes, including those with renal impairment, demonstrated lowering of blood sugar (HbA1c), weight loss and blood pressure improvements.
Under the deal, Sanofi will pay Lexicon $300m. It also includes development, regulatory and sales milestone payments of about $1.4bn.
Lexicon is also eligible to tiered, escalating double digit percentage royalties of net sales of sotagliflozin.
