Sanofi and Lexicon to develop sotagliflozin (for diabetics)November 6, 2015
Sanofi and Lexicon Pharmaceuticals have entered into a collaboration and license agreement for the development and commercialization of sotagliflozin, 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.
In a statement on Friday, Pascale Witz, Executive Vice President, Sanofi, who will lead the Global Diabetes and Cardiovascular Care Business Unit in the company’s new organizational structure, said:
“This agreement with Lexicon reinforces our commitment to helping people living with diabetes. 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.”
According to the statement, the developmental medicine sotagliflozin (LX4211) is currently being studied in two pivotal 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 glycemic 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. No increase in hypoglycemic events was seen with sotagliflozin compared to background therapy in the Phase 2 program. The adverse event profile in the Phase 2 program was similar to other products in this class and reflective of the urinary glucose excretion associated with sotagliflozin’s inhibition of SGLT-2.
Furthermore, these results indicate that sotagliflozin could have the potential to become an important option among oral anti-diabetic medicines and provide a strong rationale for the further investigation of this compound as a treatment for people with diabetes.
“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 program. 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 commercialization 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 royaltiesof net sales of sotagliflozin.
Sanofi obtains an exclusive worldwide license to develop, manufacture and commercialize sotagliflozin. Lexicon will continue to be responsible for all clinical development activities relating to type 1 diabetes and will retain 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 United States. Sanofi will be responsible for all clinical development and commercialization activities of sotagliflozin for the treatment of type 2 diabetes worldwide and will be solely responsible for the commercialization of sotagliflozin for the treatment of type 1 diabetes outside the United States. Lexicon will share in the funding of a portion of the planned type 2 diabetes development costs over the next three years, up to an aggregate of $100 million.
It has been noted in the press release that the agreement was subject to customary filing and review under the Hart-Scott-Rodino Antitrust Improvements Act.
Also, the investigational agent described above is currently under clinical development and its safety and efficacy have not been evaluated by any regulatory authority.
