Further study details as provided by Zenith Epigenetics:

Primary Outcome Measures:
  • For dose escalation only: Incidence of dose-limiting toxicities (DLT) [ Time Frame: Cycle 1 (Day 1 thru Day 28) ]
    A DLT is a treatment-related, clinically significant adverse event or laboratory abnormality occurring during the first cycle of treatment (Day 1 thru Day 28).

  • For dose escalation and dose confirmation: Incidence of treatment-related adverse events (AE) and treatment-related serious adverse events (SAE) [ Time Frame: Up to 24 months ]

Secondary Outcome Measures:
  • Measure the pharmacokinetic (PK) parameter: AUC of ZEN003694 [ Time Frame: Cycle 1 Day 1: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 1 Day 2: pre-dose; Cycle 1 Day 15: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 2 Day 1: pre-dose ]
    AUC is defined as the area under the curve (plasma concentration of drug over time).

  • Measure the PK parameter: Cmax of ZEN003694 [ Time Frame: Cycle 1 Day 1: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 1 Day 2: pre-dose; Cycle 1 Day 15: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 2 Day 1: pre-dose ]
    Cmax is defined as maximum or peak plasma concentration of drug.

  • Measure the PK parameter: Cmin of ZEN003694 [ Time Frame: Cycle 1 Day 1: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 1 Day 2: pre-dose; Cycle 1 Day 15: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 2 Day 1: pre-dose ]
    Cmin is defined as minimum or trough plasma concentration of drug.

  • Measure the PK parameter: Tmax of ZEN003694 [ Time Frame: Cycle 1 Day 1: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 1 Day 2: pre-dose; Cycle 1 Day 15: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 2 Day 1: pre-dose ]
    Tmax is defined as the time from dosing to the maximum plasma concentration.

  • Measure the PK parameter: t1/2 of ZEN003694 [ Time Frame: Cycle 1 Day 1: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 1 Day 2: pre-dose; Cycle 1 Day 15: pre-dose, 0.25, 0.5, 1, 2, 4, 6 and 8 hours post-dose; Cycle 2 Day 1: pre-dose ]
    t/12 is defined as the half-life of drug.

  • Evaluate prostate-specific antigen (PSA) response rate by PCWG2 criteria [ Time Frame: From screening up to 24 months ]
  • Evaluate radiographic response rate by PCWG2 criteria [ Time Frame: From screening up to 24 months ]
  • Evaluate median progression-free survival by PCWG2 criteria [ Time Frame: From screening up to 24 months ]
  • Evaluate circulating tumor cell (CTC) response rate during dose confirmation phase only [ Time Frame: From screening up to 12 months ]

Estimated Enrollment: 44
Study Start Date: April 2016
Estimated Study Completion Date: April 2018
Estimated Primary Completion Date: April 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Dose Escalation and Dose Confirmation - ZEN003694 Single Agent

  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Males age ≥ 18 years
  2. Metastatic, castrate resistant, histologically confirmed prostate cancer; surgically castrated or continuous medical castration for ≥ 8 weeks prior to screening
  3. Serum testosterone < 50 ng/dL determined within 4 weeks of first administration of study drug
  4. Prior progression on one or more androgen-receptor/androgen-synthesis inhibitor therapies (e.g. abiraterone, enzalutamide, apalutamide, TAK-700 and/or galeterone) by Prostate Cancer Working Group 2 (PCWG2) criteria. Prior progression on bicalutamide/nilutamide/flutamide/ketoconazole alone is not allowed.
  5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  6. Adequate laboratory parameters [absolute neutrophil (ANC), platelets, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, creatinine and coagulation parameters] at screening

Exclusion Criteria:

  1. Any history of brain metastases or prior seizure or conditions predisposing to seizure activity
  2. Have previously received an investigational BET inhibitor (including previous participation in this study or Study ZEN003694-002)
  3. Have received prior systemic anti-cancer therapy or investigational therapy within 2 weeks or five half-lives, whichever is shorter, prior to the first administration of study drug
  4. Failure to recover to Grade 1 or lower toxicity related to prior systemic therapy (excluding alopecia and neuropathy) prior to study entry
  5. Radiation therapy within 2 weeks of first administration of study drug
  6. Have received prior chemotherapy in the metastatic castration-resistant setting (prior chemotherapy in the hormone-sensitive setting is allowed provided last dose was at least 6 months prior to study entry)
  7. Currently receiving medications known to be strong inducers or inhibitors of CYP3A4 with a narrow therapeutic window. Strong inducers and inhibitors of CYP3A4 with narrow therapeutic ranges must be discontinued at least 7 days prior to the first administration of study drug.
