July 26 (Reuters) - French drugmaker Sanofi SA said on Friday it had terminated its partnership with Lexicon Pharmaceuticals Inc to develop and manufacture a drug for use with insulin in patients with type 1 and type 2 diabetes.
Lexicon shares fell nearly 40% in extended trading.
Sanofi said the termination of the partnership comes after the results of a late stage study of the drug, sotagliflozin.
However, trials of the drug will continue without Lexicon, Sanofi said.
