Phase 1 Study of ACE-232 to Treat Patients With Metastatic Castration-Resistant Prostate Cancer
Conditions
Prostate Cancer (Adenocarcinoma), mCRPC (Metastatic Castration-resistant Prostate Cancer)Drugs
ACE-232 tabletsSummary
This is an open label, phase I, multi-center study aiming to assess the safety and tolerability in patients with metastatic castration resistant prostate cancer (mCRPC).
Detailed Description
The study consists of two parts, Phase 1A dose escalation and Phase 1B dose optimization. Phase 1A aims to assess the safety, tolerability, pharmacokinetic (PK) profile, and changes in pharmacodynamic (PD) markers in patients treated with ACE-232, and to determine the maximum tolerated dose (MTD), if applicable. In Phase 1B, patients with AR gene alterations will be treated at two different dose levels to establish the recommended Phase 2 dose (RP2D).

Study Plan
ACE-232
DRUG:
ACE-232 tabletsDescription:
ACE-232 tablets will be administered orally daily as a continuous regimen together with Dexamethasone and Fludrocortisone. Subjects will continue to receive study treatment until PD as judged by local investigator review, development of unacceptable toxicity, or withdrawal of consent.
