AstraZeneca PLCAstraZeneca's SERD camizestrant (Ecamah) failed as a first-line breast cancer treatment in a late-stage trial.
Olema Pharmaceuticals shares dropped about 15% in after-hours trading Friday after AstraZeneca disclosed that its SERD and CERAN, Etcamah (camizestrant), failed as a first-line breast cancer treatment. Olema is developing its own estrogen receptor antagonist and selective estrogen receptor degrader, palazestrant. Palazestrant is in phase 3 development in a collaboration with Novartis as a first-line treatment in combination with the CDK 4/6 inhibitor Kisqali (ribociclib) for metastatic breast cancer, and it is also in phase 3 as a second- and third-line monotherapy.
