An immunotherapy from the drug firms Regeneron and Sanofi extended survival in previously untreated patients with non-small cell lung cancer, the companies said Monday.
Only one other such medicine, Merck’s Keytruda, has had a similar benefit in a similar population, said George D. Yancopoulos, Regeneron’s co-founder and chief scientific officer. He hopes, he said, that the Regeneron-Sanofi drug, called Libtayo, can provide an “alternative” to Keytruda in first-line non-small cell lung cancer.
