Outcome Measures

Primary Outcomes (3)

  • Number of patients experiencing adverse events (AEs)/serious adverse events (SAEs)

    Number of patients with incidence of adverse events and with serious adverse events including changes from baseline in laboratory parameters, vital signs, ECGs, and physical examination, etc.

    From time of information consent to 30 days post last dose, up to approximately 37 months

  • Number of patients experiencing dose limiting toxicity (DLT), as defined in the protocol

    A DLT is defined as any toxicity events related to ACE-232 that occur from the first dose of study treatment until the planned end date of Cycle 1 (DLT assessment period), meeting the criteria specified in protocol.

    From the first dose of ACE-232 on Cycle 1 Day 1 up to and including the planned end of Cycle 1 (at the end of 28 days)

  • Recommended Phase 2 dose (RP2D) and/or maximum tolerated dose (MTD)

    RP2D will be finally determined by the SMC and sponsor based on all data from the dose escalation module and backfill module, as well as the exposure-response relationship evaluated (if available). MTD is defined as the maximum dose level at which ≤1 patient have DLTs during the DLT observation period, and it should be determined with 6 evaluable patients.

    Up to approximately 37 months

Secondary Outcomes (8)

  • Pharmacokinetics characterization by using Area under the plasma concentration versus time curve (AUC)

    Up to approximately 37 months

  • Pharmacokinetics characterization by using Maximum concentration (Cmax)

    Up to approximately 37 months

  • Prostate Specific Antigen (PSA) response

    Up to approximately 37 months

  • Objective Response Rate (ORR)

    Up to approximately 37 months

  • Duration of Response (DoR)

    Up to approximately 37 months

  • +3 more secondary outcomes

Other Outcomes (1)

  • Gene aberrations

    Up to approximately 37 months

Study Arms (1)

ACE-232

EXPERIMENTAL
Drug: ACE-232 tablets

Interventions

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.

ACE-232

  • Severe cardiovascular disorders.
  • Known gastrointestinal (GI) disorder or GI procedure
  • History of gastric and duodenal perforation.
  • History of pituitary dysfunction.
  • Poorly controlled diabetes mellitus.
  • Active or uncontrolled autoimmune disease
  • Active infections, or a known history of HIV infection, or a known active hepatitis B or C, or a known active tuberculosis.
  • Other malignancies requiring treatment within 3 years prior to the first dose of study drug
  • Known allergy or hypersensitivity to any of the excipients of ACE-232.
  • Has other medical conditions that at the discretion of the investigator interfere with safety or efficacy evaluation, or treatment compliance.
