Dose Escalation and Dose Confirmation - ZEN003694 Single AgentExperimentalZEN003694 will be administered orally as a single agent once daily in 28-day cycles, enrolling mCRPC patients.
Receives: Drug: ZEN003694

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. For dose escalation only: Incidence of dose-limiting toxicities (DLT)

    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).

    Measured: Cycle 1 (Day 1 thru Day 28)

  2. For dose escalation and dose confirmation: Incidence of treatment-related adverse events (AE) and treatment-related serious adverse events (SAE)

    Measured: Up to 24 months

Secondary outcomes (9)
  1. Measure the pharmacokinetic (PK) parameter: AUC of ZEN003694

    AUC is defined as the area under the curve (plasma concentration of drug over time).

    Measured: 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

  2. Measure the PK parameter: Cmax of ZEN003694

    Cmax is defined as maximum or peak plasma concentration of drug.

    Measured: 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

  3. Measure the PK parameter: Cmin of ZEN003694

    Cmin is defined as minimum or trough plasma concentration of drug.

    Measured: 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

  4. Measure the PK parameter: Tmax of ZEN003694

    Tmax is defined as the time from dosing to the maximum plasma concentration.

    Measured: 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

  5. Measure the PK parameter: t1/2 of ZEN003694

    t/12 is defined as the half-life of drug.

    Measured: 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

  6. Evaluate prostate-specific antigen (PSA) response rate by PCWG2 criteria

    Measured: From screening up to 24 months

  7. Evaluate radiographic response rate by PCWG2 criteria

    Measured: From screening up to 24 months

  8. Evaluate median progression-free survival by PCWG2 criteria

    Measured: From screening up to 24 months

  9. Evaluate circulating tumor cell (CTC) response rate during dose confirmation phase only

    Measured: From screening up to 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ZEN003694 in people with Metastatic Castration-Resistant Prostate Cancer, run by Zenith Epigenetics at 8 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

For dose escalation only: Incidence of dose-limiting toxicities (DLT) (time frame: Cycle 1 (Day 1 thru Day 28)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Nov 2017.
