What is being measured

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

  1. Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Serious TEAEs, and TEAEs Leading to Dose Interruption, Reduction, or Study Drug Discontinuation (Excluding Grade 5 Disease Progression)

    An adverse event (AE) is any untoward, undesired, or unplanned event that does not need to be causally related to treatment. A serious adverse event (SAE) is an AE that: results in death, is life-threatening, requires inpatient hospitalization or prolongation of an existing hospitalization, results in a persistent or significant disability or incapacity, results in a congenital anomaly or birth defect, or important medical events that may not result in death, be life-threatening, or require hospitalization may be considered SAEs when, based on appropriate medical judgment, they may jeopardize the patient and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. Relatedness to study medication was graded as either, probably, possibly, unlikely, or unrelated. Events were categorized according to the Common Toxicity Criteria for Adverse Events (CTCAE) Grade 1=mild, Grade 2=moderate, Grade 3=severe, Grade 4=life-threatening, Grade 5=death.

    Measured: From the first dose of study drug up to 28 days post last dose. Median duration of telaglenastat treatment was 92 days and that for nivolumab treatment was 84 days.

  2. Number of Participants With Clinically Significant Treatment-Emergent Values in Hematology, Serum Chemistry Panel, Vital Signs or Weight

    Hematology assessments included: hemoglobin; hematocrit, red blood cell count, white blood cell count with differential, and platelet count. Serum chemistry panel included: sodium, potassium, chloride, carbon dioxide, calcium, glucose, blood urea nitrogen, total protein, albumin, total bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, creatinine, thyroid stimulating hormone. Vital sign assessments included systolic and diastolic blood pressures, pulse (heart) rate, respiratory rate, temperature, and body weight.

    Measured: From the first dose of study drug up to 28 days post last dose. Median duration of telaglenastat treatment was 92 days and that for nivolumab treatment was 84 days.

  3. Overall Response Rate (ORR) Per Investigator Assessed Response Evaluation Criteria in Solid Tumors (RECIST) v1.1

    ORR is defined as the percentage of participants with complete response (CR) or partial response (PR) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. CR or PR was required to be sustained for 4 weeks when confirmation was reported.

    • CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm.
    • PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    Measured: up to a maximum of 2.8 years

  4. Duration of Response (DOR) Per Investigator Assessed RECIST v1.1

    DOR is defined as the time between the first documentation of a PR or a CR to the first documentation of progressive disease (PD) or death, whichever occurred first. DOR was censored at the date of last radiographic disease if the patient was alive and progression free at the time of database lock, PD, or death occurred after missing data for 2 consecutive radiographic disease assessments, or patient received non-protocol treatment prior to documentation of disease progression.

    • CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm.
    • PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
    • PD: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.

    Measured: up to a maximum of 2.8 years

Secondary outcomes (2)
  1. Progression-Free Survival (PFS) Per RECIST v1.1

    PFS was defined as time from the first dose date to the earlier of either PD per RECIST v1.1 or death from any cause. The duration of PFS was censored at the date of last radiographic disease if the patient was alive and progression-free at the time of analysis data cutoff, disease progression, or death occurred after missing data for 2 consecutive radiographic disease assessments, or patient received non-protocol treatment prior to documentation of disease progression.

    • PD: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.

    Measured: up to a maximum of 2.8 years

  2. Overall Survival

    Overall survival was defined as the time from the first dose date to death due to any cause. For participants alive at time of analysis, overall survival was censored at the time when the participant was last known to be alive.

    Measured: up to a maximum of 2.8 years

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CB-839 and Nivolumab in people with Clear Cell Renal Cell Carcinoma (ccRCC) and Melanoma, run by Calithera Biosciences, Inc at 17 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 7 inclusion and 16 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 17 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 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 17 Mar 2023). 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 With Treatment-Emergent Adverse Events (TEAEs), Serious TEAEs, and TEAEs Leading to Dose Interruption, Reduction, or Study Drug Discontinuation (Excluding Grade 5 Disease Progression) (time frame: From the first dose of study drug up to 28 days post last dose. Median duration of telaglenastat treatment was 92 days and that for nivolumab treatment was 84 days.). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02771626, which also lists 1 linked publication.

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 17 Mar 2023.
