A Study of Pembrolizumab/Vibostolimab (MK-7684A) in Relapsed/Refractory Hematological Malignancies (MK-7684A-004, KEYVIBE-004)

Phase 2
Completed
Conditions
Hematological Malignancies
Interventions
Biological: Pembrolizumab/vibostolimab coformuation
Registration Number
NCT05005442
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

The purpose of the study is to determine the safety and tolerability of pembrolizumab/vibostolimab (MK-7684A) in hematological malignancies. This study will also evaluate the overall response rate (ORR), the duration of response (DOR), and disease control rate (DCR) following administration of pembrolizumab/vibostolimab. In addition, this study will characterize pharmacokinetic (PK) profile of vibostolimab (MK-7684).

Pembrolizumab/vibostolimab coformulationPembrolizumab/vibostolimab coformuationParticipants will receive pembrolizumab/vibostolimab (coformulation of 200 mg pembrolizumab and 200 mg vibostolimab) via intravenous IV infusion once every 3 weeks (Q3W) for up to 35 cycles up to approximately 2 years.
Primary Outcome Measures
NameTimeMethod
Number of Participants Who Discontinued Study Treatment Due to an AEUp to approximately 24 months

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 adverse event. The number of participants discontinued from the study treatment due to an AE will be reported.

Number of Participants with a Dose-Limiting Toxicity (DLT)Up to approximately 6 weeks

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). Number of participants who experience a DLT per CTCAE 5.0 will be reported.

Number of Participants Who Experienced an Adverse Event (AE)Up to approximately 27 months

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 adverse event. The number of participants who experience an AE will be reported.

Secondary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)Up to approximately 24 months

ORR is defined as the percentage of participants who have a response as defined by the specific disease criteria of the hematological malignancy. The percentage of participants who experience a response will be presented.

Maximum Concentration (Cmax) of VibostolimabPostdose: after end of infusion (up to ~10 minutes) at Cycles 1 and 8. Cycle = 3 weeks

Cmax is the maximum concentration of the drug observed in plasma. Blood samples collected post dose will be used to determine Cmax of Vibostolimab.

Lowest Plasma Concentration (Ctrough) of VibostolimabPredose at Cycles 1, 2, 4, 8, and every 12 weeks afterwards (up to ~2 years). Cycle = 3 weeks

Ctrough is the lowest concentration reached by a drug before the next dose is administered. Blood samples collected predose will be used to determine Ctrough of Vibostolimab.

Disease Control Rate (DCR)Up to approximately 24 months

DCR is defined as the percentage of participants who have a Complete Response (CR), a Partial Response (PR), or Stable Disease (SD). The percentage of participants who experience a CR, a PR, or SD will be presented.

Duration of Response (DOR)Up to approximately 24 months

DOR is the time from response (R) to progression/death (P/D). The DOR will be presented.
