What is being measured

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

  1. Overall Response Rate (ORR) in VHL Disease-Associated ccRCC Tumors

    ORR was defined as the percentage of participants in the analysis population who have a best confirmed response of Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1). ORR was assessed by independent review committee (ICR) for the primary analysis.

    Measured: Up to approximately 76 months

Secondary outcomes (11)
  1. Progression-free Survival (PFS) in VHL Disease-Associated ccRCC Tumors

    PFS was defined as the interval from the start of study treatment to the first documented Progressive Disease (PD) or death from any cause, whichever occurs first. Per RECIST 1.1, PD was defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered PD.

    Measured: Up to approximately 76 months

  2. Duration of Response (DOR) in VHL Disease-Associated ccRCC Tumors

    DOR was defined as the interval from the first documented evidence of a CR (disappearance of all target lesions) or a PR (at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1 until PD or death due to any cause, whichever occurs first, in participants demonstrating a best confirmed response of CR or PR. Per RECIST 1.1, PD was defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered PD.

    Measured: Up to approximately 76 months

  3. Time to Response (TTR) in VHL Disease-Associated ccRCC Tumors

    TTR was defined as the interval from the start of study treatment to the first documentation of a response per RECIST 1.1, and calculated for participants with a best confirmed response of CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions).

    Measured: Up to approximately 76 months

  4. Overall Response Rate (ORR) in VHL Disease-Associated Non-ccRCC Tumors

    ORR was defined as the percentage of participants in the analysis population who have a best confirmed response of Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1).

    Measured: Up to approximately 76 months

  5. Progression-free Survival (PFS) in VHL Disease-Associated Non-ccRCC Tumors

    PFS was defined as the interval from the start of study treatment to the first documented PD or death from any cause, whichever occurs first. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered PD.

    Measured: Up to approximately 76 months

  6. Duration of Response (DOR) in VHL Disease-Associated Non-ccRCC Tumors

    DOR was defined as the interval from the first documented evidence of a CR (disappearance of all target lesions) or a PR (at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1 until Progressive Disease (PD) or death due to any cause, whichever occurs first, in participants demonstrating a best confirmed response of CR or PR. Per RECIST 1.1, PD was defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered PD.

    Measured: Up to approximately 76 months

  7. Time to Response (TTR) in VHL Disease-Associated Non-ccRCC Tumors

    TTR was defined as the interval from the start of study treatment to the first documentation of a response per RECIST 1.1, and calculated for participants with a best confirmed response of CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions).

    Measured: Up to approximately 76 months

  8. MK-3795 Plasma Concentration

    Blood samples for the determination of MK-3795 concentration were collected at pre-specified timepoints before and after administration of study intervention.

    Measured: Week 1: pre-dose and 6 hours post-dose, Week 3, 5, 9, 13, and 17: pre-dose

  9. MK-3795 Metabolite Plasma Concentration

    Blood samples for the determination of MK-3795 metabolite concentration were collected at pre-specified timepoints before and after administration of study intervention.

    Measured: Week 1: pre-dose and 6 hours post-dose, Week 3, 5, 9, 13, and 17: pre-dose

  10. Number of Participants Who Experienced One or More Adverse Events (AEs)

    An AE was defined as any untoward medical occurrence in a participant regardless of its causal relationship to study treatment. An AE can be any unfavorable and unintended sign (including any clinically significant abnormal laboratory test result), symptom, or disease temporally associated with the use of the study drug, whether or not it was considered to be study drug related.

    Measured: Up to approximately 76 months

  11. Number of Participants Who Discontinued Study Intervention Due to an AE

    An AE was defined as any untoward medical occurrence in a participant regardless of its causal relationship to study treatment. An AE can be any unfavorable and unintended sign (including any clinically significant abnormal laboratory test result), symptom, or disease temporally associated with the use of the study drug, whether or not it is considered to be study drug related.

    Measured: Up to approximately 74 months

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 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 24 Sep 2024). 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?

Overall Response Rate (ORR) in VHL Disease-Associated ccRCC Tumors (time frame: Up to approximately 76 months). 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 NCT03108066, 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 24 Sep 2024.
