A first-in-human clinical trial to test the investigational treatment ONCT-534 in participants with metastatic castration-resistant prostate cancer. The main questions it aims to answer are:
This is a dose escalation and expansion study where participants will receive daily oral doses of ONCT-534.
This is a Phase 1/2 multi-center study to investigate the safety, tolerability, and anti-tumor acitivity of ONCT-534 in patients with relapsed or refractory metastatic castration-resistant prostate cancer. The study consists of 2 phases: a Phase 1 Dose Escalation and a Phase 2 Dose Expansion.

| ONCT-534 | Drug | ONCT-534 is a dual-action androgen receptor inhibitor (DAARI) with a novel mechanism of action that includes inhibition of AR function and degradation of the AR protein mediated by interaction with the N-terminal domain (NTD) of the AR. ONCT-534 has demonstrated preclinical activity in prostate cancer models against both unmutated androgen receptor (AR), and against multiple forms of AR alteration, including those with AR amplification, mutations in the AR ligand binding domain (LBD), and splice variants with loss of the AR LBD. |
