Olema Oncology Announces Publication of Data Highlighting Palazestrant’s Ability to Inhibit Wild-Type and Mutant ER+ Breast Cancer Both as Monotherapy and in Combination with CDK4/6 Inhibitors
The paper, titled “Palazestrant (OP-1250), a Complete Estrogen Receptor Antagonist, Inhibits Wild-type and Mutant ER-positive Breast Cancer Models as Monotherapy and in Combination”, describes the scientific background underlying the design, discovery and optimization of palazestrant.
- The paper, titled “Palazestrant (OP-1250), a Complete Estrogen Receptor Antagonist, Inhibits Wild-type and Mutant ER-positive Breast Cancer Models as Monotherapy and in Combination”, describes the scientific background underlying the design, discovery and optimization of palazestrant.
- “What’s even more exciting is to see how faithfully the pre-clinical research predicted the behavior of palazestrant now that it is in late-stage clinical development.
- In mouse xenograft models, palazestrant demonstrated excellent pharmacokinetics, was well tolerated, showed synergy with CDK4/6 inhibitors, and was highly effective at reducing tumor growth in both wild-type and ESR1-mutant ER+ breast cancer.
- In addition, in an ESR1-mutant intercranial xenograft model, palazestrant inhibited tumor growth and improved survival of animals with CNS metastases, even after stopping drug treatment.
