The Genesis of Olema Oncology

Olema Oncology was founded in 2007 by Peter Kushner, with its incorporation dating back to August 6, 2006. The company's mission was to develop novel therapies for women's cancers, specifically targeting resistance mechanisms in ER+ breast cancer.

  • Founded in 2007 by Peter Kushner.
  • Incorporated on August 6, 2006, in San Francisco, California.
  • Focused on addressing resistance in ER+ breast cancer.
  • Aimed to overcome limitations of existing treatments like tamoxifen.

The company's early strategy centered on discovering and developing innovative small molecule therapies. A key element of this approach was the development of palazestrant (OP-1250), designed as a complete estrogen receptor antagonist (CERAN) and a selective ER degrader (SERD). The goal for palazestrant was to effectively block ER-driven transcriptional activity in both standard and mutated forms of metastatic ER+ breast cancer. This commitment to pioneering treatments reflects the core of the Mission, Vision & Core Values of Olema Oncology.

Investor confidence in Olema Oncology's innovative direction was evident in its Series C financing round. In October 2020, the company secured $85 million, with Vivo Capital leading the investment. Other notable participants included BVF Partners and Janus Henderson Investors. This substantial funding was critical for advancing the clinical development of OP-1250 and bolstering overall research and development efforts, marking a significant milestone in the Olema Oncology company background.
