AZD9750 / AstraZeneca - LARVOL DELTA

Preclinical mechanistic PK/PD-efficacy modeling for AZD9750, a novel oral androgen receptor degrader (PROTAC), to support dose selection during early clinical development (AACR 2025) - "This study provides quantitative mechanistic insights into the links between compound exposure, biomarker modulation (AR) and anti-tumor responses, supporting our understanding of the required target modulation needed for maximal anti-tumor effects in these two hormone sensitive patient-derived tumor models. This mechanistic understanding is valuable to contextualize compound-induced PD modulation in patients, for given doses and schedules."

AZD9750, a novel androgen receptor proteolysis targeting chimera (AR-PROTAC) for the treatment of prostate cancer (AACR 2025) - "Several androgen receptor pathway inhibitors (ARPIs) have been developed and approved for the treatment of locally advanced and metastatic prostate cancer, including the androgen synthesis inhibitor, abiraterone and the AR antagonists, enzalutamide, apalutamide and darolutamide. These data confirm that AZD9750 is a potent oral degrader of AR that leads to anti-tumor efficacy in a range of hormone-sensitive and castrate-resistant PDX models. Through degradation of AR, including mutant and amplified forms of the receptor, it has the potential to overcome key resistance mechanisms arising to current standard of care therapies and provide benefit to patients with prostate cancer."
