Mirati Therapeutics Inc. posted new data for its highly anticipated KRAS cancer fighter, adagrasib (MRTX-849), showing mixed results compared to its already-marketed competition, Lumakras (sotorasib) from Amgen Inc. The new data came from a cohort of patients with KRAS-G12C non-small-cell lung cancer enrolled in Mirati’s registration-enabling phase II Krystal-1 study. Each had received at least one prior systemic therapy, most with a PD-1/L1 inhibitor following or in combination with chemotherapy.
Phase II melanoma data characterized by Iovance Biotherapeutics Inc. as positive failed to excite Wall Street, which took away 53.6% of the company’s share value (NASDAQ:IOVA), or $8.10, and pushed the closing price to $7.02 on May 27. The San Carlos, Calif.-based firm offered results from registrational cohort 4 (n=87) of the C-144-01 study testing lifileucel (LN-144, autologous tumor infiltrating lymphocytes) in advanced melanoma.
