What is being measured

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

  1. Percentage of Participants Experiencing a Dose-limiting Toxicity (DLT)

    A DLT is defined as an event with toxicity including the type, severity, time of onset, time of resolution, and the probable association with study treatment that are not due to pre-existing conditions as defined by the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE 5.0). Per protocol participants who switched over from MK-1088 monotherapy into MK-1088 100 mg + Pembrolizumab combination therapy completed the DLT evaluation period in the monotherapy arm assigned. Percentage of participants who experienced a DLT are presented.

    Measured: Up to 21 days

  2. Percentage of Participants Experiencing an Adverse Event (AE)

    An AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. Safety data from participants who experienced disease progression in the monotherapy arm and crossed over into the combination arm are summarized in their initial monotherapy dose group until the time of cross over and are summarized separately thereafter. The percentage of participants who experienced an AE are presented.

    Measured: Up to ~13 months

  3. Percentage of Participants Discontinuing Study Treatment Due to an AE

    An AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. Safety data from participants who experienced disease progression in the monotherapy arm and crossed over into the combination arm are summarized in their initial monotherapy dose group until the time of cross over and are summarized separately thereafter. The percentage of participants who discontinued study treatment due to an AE is presented.

    Measured: Up to ~10 months

Secondary outcomes (3)
  1. Area Under the Plasma Concentration-time Curve (AUC) of MK-1088

    AUC of MK-1088 determined by blood samples collected pre-dose and at designated timepoints post-dose are presented.

    Measured: Pre-dose and 1, 2, 4, and 8 hours post-dose on Cycle 1 Day 1 and Cycle 2 Day 1; Pre-dose on Cycle 1 Day 2 and Cycle 2 Day 2; Pre-dose on Cycle 3, Cycle 4 and every 4 cycles up to ~3.5 months. Each cycle = 21 days

  2. Maximum Plasma Concentration (Cmax) of MK-1088

    Cmax of MK-1088 determined by blood samples collected pre-dose and at designated timepoints post-dose are presented.

    Measured: Pre-dose and 1, 2, 4, and 8 hours post-dose on Cycle 1 Day 1 and Cycle 2 Day 1; Pre-dose on Cycle 1 Day 2 and Cycle 2 Day 2; Pre-dose on Cycle 3, Cycle 4 and every 4 cycles up to ~3.5 months. Each cycle = 21 days

  3. Objective Response Rate (ORR) Per Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) or Prostate Cancer Working Group (PCWG)-Modified RECIST 1.1 as Assessed by Investigator

    ORR is defined as the percentage of participants who have a 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 RECIST 1.1 or Prostate Cancer Working Group (PCWG)-modified RECIST 1.1 as assessed by investigator. Efficacy data from participants who experienced disease progression in the monotherapy arm and crossed over into the combination arm will be summarized in their initial monotherapy dose group until the time of cross over and will be summarized separately thereafter. The percentage of participants who experience a CR or PR as assessed by the investigator based on RECIST 1.1 is presented.

    Measured: Up to ~13 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing MK-1088 and Pembrolizumab in people with Advanced Solid Tumors, run by Merck Sharp & Dohme LLC at 13 sites in 5 countries.

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 18 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 8 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States, Denmark, Switzerland, Canada, Israel. 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 4 Oct 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?

Percentage of Participants Experiencing a Dose-limiting Toxicity (DLT) (time frame: Up to 21 days). The study lists 3 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 8 Nov 2024.
