SAN FRANCISCO, Nov. 22, 2021 (GLOBE NEWSWIRE) — Olema Pharmaceuticals, Inc. (“Olema” or “Olema Oncology,” Nasdaq: OLMA), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of targeted therapies for women’s cancers, today announced two poster presentations on OP-1250, an investigational complete estrogen receptor (ER) antagonist (CERAN) and a selective ER degrader (SERD) in development for the treatment of metastatic breast cancer and other women’s cancers, at the upcoming San Antonio Breast Cancer Symposium (SABCS) meeting being held December 7-10, 2021, at the Henry B. Gonzalez Convention Center in San Antonio, Texas.

“We look forward to sharing the first clinical data for OP-1250, our investigational complete estrogen receptor antagonist (CERAN), at SABCS, one of the most important medical meetings of the year for scientific exchange on advancing care for breast cancer,” said Sean P.
