What is being measured

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

  1. Number of Participants Who Experience a Dose-Limiting Toxicity (DLT) During the First 28-day Cycle of Combination Treatment In Phase 1

    Toxicities were graded using the National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE) version 4.03. Any of the following events considered to be causally related to treatment with mocetinostat in combination with durvalumab that occurred during Phase 1 were considered a DLT:

    • Any Grade 4 immune-related adverse event (irAE)
    • Grade 3 or greater colitis
    • Grade 3 or greater noninfectious pneumonitis
    • Grade 2 pneumonitis that did not resolve to ≤ Grade 1 within 3 days of the initiation of maximal supportive care
    • Grade 3 irAE (excluding colitis or pneumonitis) that:
    • Did not resolve to Grade 2 within 3 days after onset of the event despite optimal medical management including systemic corticosteroids, or
    • Did not resolve to Grade ≤1 or Baseline within 14 days
    • Liver transaminase elevation >8×upper limit of normal (ULN) or total bilirubin >5×ULN
    • Grade 3 or greater non-irAE, except nausea, vomiting, anorexia, dehydration, or diarrhea

    Measured: 28 days

  2. Objective Response Rate (ORR)

    Objective Response Rate (ORR) was defined as the number of participants documented to have a confirmed Complete Response (CR) or Partial Response (PR). Complete Response was defined as the complete disappearance of all target lesions with the exception of nodal disease. Partial Response was defined at least a 30% decrease in the sum of diameters of target measurable lesions. Responses were determined by the investigator per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Participants without response data were counted as non-responders.

    Inferential statistical analyses were conducted for Phase 2 only, as efficacy was not part of the Phase 1 objectives.

    Measured: Up to approximately 10 months

Secondary outcomes (10)
  1. Number of Participants Experiencing Treatment-Emergent Adverse Events

    Measured: Day 1 to 28 days after last dose of study treatment (up to a maximum of 125 weeks in phase 1 and a maximum of 92 weeks in phase 2)

  2. Duration of Response (DR)

    DR was defined as the time in days from date of the first documentation of objective response (Complete Response [CR] or Partial Response [PR]) to the first documentation of objective Progressive Disease (PD) or to death due to any cause in the absence of documented PD. DR was only calculated for the subgroup of participants who achieved a Best Overall Response of CR or PR and was presented for responses assessed by Investigator's assessment.

    Data is displayed for Phase 2 only, as no participants experienced an objective response (CR or PR) during Phase 1.

    Measured: Up to approximately 10 months

  3. Clinical Benefit Rate (CBR)

    Clinical benefit rate (CBR) was defined as the number of participants documented to have a confirmed Complete Response (CR), Partial Response (PR), or Stable Disease (SD) according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Participants who were not be able to be assessed for response were counted as non-responders.

    Measured: Up to approximately 10 months

  4. Progression-Free Survival (PFS)

    Progression-free survival (PFS) was defined as the time from date of first study treatment to first Progressive Disease (PD) or death due to any cause in the absence of documented PD per RECIST v1.1

    Measured: Randomization until progressive disease or death due to any cause (up to 42 months)

  5. 1-Year Survival Rate

    Measured: 1 year

  6. Overall Survival (OS)

    OS was defined as the time from first dose of study treatment to the date of death due to any cause.

    Measured: From date of first study treatment until death due to any cause (up to 42 months)

  7. Concentration of Mocetinistat in Blood Plasma

    Measured: Cycle 1 Day 1 pre-dose, 1, 3, and 7 hours post-dose, Cycle 1 Day 15 pre-dose and 1 hour post-dose, Cycle 2 Day 1 pre-dose and 1 hour post-dose, Cycle 3 Day 1 pre-dose and 1 hour post-dose and Cycle 7 Day 1 pre-dose (each cycle is 28 days)

  8. Concentration of Durvalumab in Blood Plasma

    Plasma concentration of Durvalumab was evaluated. All participants received the same Durvalumab dose regardless of Mocetinistat dose group.

    Measured: Cycle 1 Day 1 pre-dose + end of infusion, Cycle 1 Day 15 pre-mocetinostat dose, Cycle 2 Day 1 pre-dose, Cycle 3 Day 1 pre-dose, Cycle 4 Day 1 pre-dose + end of infusion, Cycle 7 Day 1 pre-dose + 90 days after participant's last dose (Up to max 133 weeks)

  9. Number of Participants With the Presence of Anti-Drug Antibody (ADA) in the Blood

    Measured: Up to approximately 10 months

  10. Number of Participants With Tumor Expression of Programmed Cell Death Ligand 1 (PD-L1) at Baseline

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Mocetinostat - 50 mg, Mocetinostat - 70 mg and Mocetinostat - 90 mg in people with Advanced Cancer, run by Mirati Therapeutics Inc. at 15 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 3 inclusion and 3 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: stopped early, as of the sponsor's last update on 6 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Apr 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants Who Experience a Dose-Limiting Toxicity (DLT) During the First 28-day Cycle of Combination Treatment In Phase 1 (time frame: 28 days). 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 6 Apr 2021.
