About this study

Official title: Phase 1 Trial of Single Agent MK-4166 and MK-4166 in Combination With Pembrolizumab in Subjects With Advanced Malignancies

This is planned to be a 5-part dose-escalation study to determine the safety and tolerability of MK-4166 monotherapy and MK-4166 plus pembrolizumab combination therapy, and to establish the maximum tolerated dose (MTD) or maximum administered dose (MAD) of MK-4166 and MK-4166 plus pembrolizumab by defining dose-limiting toxicities (DLTs) in participants with advanced solid tumors.

Read the detailed description

In Part A, MK-4166 doses will be escalated quickly in successive cohorts and based on safety events may progress to Part B, in which the preliminary MTD will be identified. Based on safety events the study may progress to Part C in which the MTD will be confirmed. In Part D, participants will receive escalating doses of MK-4166 plus a fixed dose of pembrolizumab (MK-3475) 200 mg to determine the MTD for MK-4166 in combination with pembrolizumab. Based on safety events in Part D, the study may progress to Part E in which the MTD for MK-4166 in combination with pembrolizumab will be confirmed.

With Amendments 05/06, the dose confirmation Part C will be removed and the dose confirmation Part E (combination of MK-4166 and pembrolizumab) will be limited to participants with advanced malignant melanoma.

What is being measured

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

  1. Number of Participants Experiencing Dose-Limiting Toxicities (DLTs)

    DLT's were assessed during the first cycle (21 days) for each dose level and included the following if assessed by the Investigator to be possibly, probably or definitely related to MK-4166 or MK-4166 plus pembrolizumab combination: Grade 4 non-hematologic toxicity; Grade 4 hematologic toxicity lasting ≥7 days, except thrombocytopenia (Grade 4 thrombocytopenia of any duration or Grade 3 thrombocytopenia if associated with bleeding); Grade 3 non-hematologic toxicity lasting >3 days despite optimal supportive care; Grade 3 nausea, vomiting or diarrhea if >3 days despite optimal supportive care; any Grade 3 or Grade 4 non-hematologic laboratory abnormality if medical intervention is required or if leading to hospitalization or if persisting for >1 week; febrile neutropenia Grade 3 or Grade 4; any drug-related AE which caused participant to discontinue treatment during Cycle 1; Grade 5 toxicity; any treatment-related toxicity which caused a >2 week delay in initiation of Cycle 2.

    Measured: Cycle 1 (up to 21 days)

  2. Number of Participants Experiencing Adverse Events (AEs)

    An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavourable 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 (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE.

    Per protocol, the number of participants experiencing an AE was assessed and reported by arm (MK-4166 monotherapy and MK-4166 plus pembrolizumab combination therapy) as well as by dose cohort.

    Measured: From first dose up to 90 days post last dose (up to 27 months)

  3. Number of Participants Discontinuing Study Treatment Due to AEs

    An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavourable 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 (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE.

    Per protocol, the number of participants discontinuing study treatment due to AEs was assessed and reported by arm (MK-4166 monotherapy and MK-4166 plus pembrolizumab combination therapy) as well as by dose cohort.

    Measured: Up to approximately 24 months

Per protocol, participants receiving MK-4166 monotherapy were excluded from this analysis.

    Measured: Cycles 1-4: Day 1 pre-dose, at end of pembro infusion (up to 10 minutes), at end of MK-4166 infusion (up to 10 minutes), ~2 hours after start of MK-4166 infusion, Days 2, 3, 8, 15. Each cycle was 21 days. (Up to ~3 months)

  16. Apparent Volume of Distribution (V) of Pembrolizumab Over Time

    Blood samples were collected at pre-specified time points during Cycles 1-4 from MK-4166 plus pembrolizumab combination cohorts only and plasma isolated for analysis of pembrolizumab V. V was defined as the theoretical volume that would be necessary to contain the total amount of administered pembrolizumab at the same concentration that it is observed in the blood plasma. Pembrolizumab V was reported by dose cohort for all participants that received MK-4166 plus pembrolizumab combination therapy. Per protocol, participants receiving MK-4166 monotherapy were excluded from this analysis.

    Measured: Cycles 1-4: Day 1 pre-dose, at end of pembro infusion (up to 10 minutes), at end of MK-4166 infusion (up to 10 minutes), ~2 hours after start of MK-4166 infusion, Days 2, 3, 8, 15. Each cycle was 21 days. (Up to ~3 months)

  17. Glucocorticoid-Induced Tumor Necrosis Factor Receptor-Related Protein (GITR) Receptor Availability Following MK-4166 Administration

    GITR protein receptor is internalized upon binding by MK-4166. To evaluate GITR target engagement, a GITR receptor availability assay was developed to assess the availability of cell surface GITR following administration of MK-4166. GITR was detected on CD4+CD25+ and CD4+CD95+ T-cell sub-populations in peripheral blood using flow cytometry. GITR receptor availability on representative CD4+ CD25+ T cell subsets following MK-4166 administration was reported over time for each dose cohort.

    Measured: Cycle 1 Day 1: at end of infusion (up to 10 minutes), 2 hours post-infusion, Cycle 1 Days 2, 3, 5, 8, 15, Cycle 2 Day 1 pre-dose. Each cycle was 21 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MK-4166 and Pembrolizumab in people with Solid Tumor, run by Merck Sharp & Dohme LLC.

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 19 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 28 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 31 Jul 2020). 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 Experiencing Dose-Limiting Toxicities (DLTs) (time frame: Cycle 1 (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?

On the ClinicalTrials.gov record for NCT02132754, 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 28 Jan 2021.
