Sotagliflozin is an orally-delivered small molecule compound that we and Sanofi are developing for the treatment of type 1 and type 2 diabetes mellitus. Sotagliflozin was internally generated by our scientists and inhibits both sodium-glucose cotransporter 2, or SGLT2, a transporter responsible for most of the glucose reabsorption performed by the kidney, and sodium-glucose cotransporter 1, or SGLT1, a transporter responsible for glucose and galactose absorption in the gastrointestinal tract. Our scientists identified mice lacking SGLT1, SGLT2 or both as having potent anti-diabetic phenotypes across multiple measures of glucose control and metabolism, and found that compounds inhibiting both targets had a favorable preclinical profile relative to compounds selective for SGLT2.
We have entered into a collaboration and license agreement with Sanofi under which we granted Sanofi an exclusive, worldwide (excluding Japan), royalty-bearing right and license to develop, manufacture and commercialize sotagliflozin. Under the alliance, we are responsible for conducting all clinical development activities relating to type 1 diabetes and Sanofi is responsible for conducting all clinical development activities relating to type 2 diabetes. We have 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 the 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). Applications for regulatory approval to market sotagliflozin for the treatment of type 1 diabetes are currently under review in the United States and the European Union.
|This figure depicts a nephron, the basic functional unit of the kidney. The glucose reabsorption transporter, SGLT2, is expressed in the first segment of the proximal convoluted tubule (PCT S1) and is responsible for most of the glucose reabsorption that happens in the kidney where SGLT1 has a lesser role. Abbreviations: PCT S1 and S2, proximal convoluted tubule segments 1 and 2; PST S3, proximal straight tubule segment 3.|
|SGLT1 is the primary transporter for absorption of glucose and galactose in the gastrointestinal tract.|
