A previous version of this article incorrectly described treatment cohorts in this study. It has been updated.
Exelixis Inc. EXEL, -0.35% shares fell in the extended session Thursday after the biotech drug maker said a late-stage clinical study testing its kidney cancer drug treatment in combination with a Roche cancer drug did not meet its intended endpoint. Exelixis shares fell 6% after hours, following a 1.7% decline to close the regular session at $17.18. In the 522-patient study, kidney cancer patients were either given a combination of Roche’s atezolizumab and Exelexis’s cabozantinib, or cabozantinib alone. Exelixis said it will release detailed findings at a medical meeting soon, but stated that survival rates without disease progression in patients given the combo treatment were no better than those given cabozantinib alone.
