Current Primary Outcome Measures  ICMJE
 (submitted: December 1, 2020)
  • Number of participants with a Dose Limiting Toxicity (DLT) [ Time Frame: Up to 6 weeks ]
    DLTs will be assessed during the first 6 weeks (2 cycles) of treatment for the Dose Escalation and the first 3 weeks (1 cycle) of treatment for the Dose Confirmation. DLT is defined as toxicity that is possibly, probably, or definitely related to study therapy and may result in a change in the given dose. DLTs include Grade (Gr)4 non-hematologic toxicity (not laboratory); Gr 4 hematologic toxicity lasting ≥7 days (except thrombocytopenia); most non-hematologic AEs ≥ Gr 3 in severity; any Gr 3 or Gr 4 non-hematologic laboratory value that requires clinically significant medical intervention, leads to hospitalization, persists for >1 week, or results in a drug-induced liver injury; Gr 3 or Gr 4 febrile neutropenia; a prolonged delay in initiating Cycle 2 or 3 of Dose Escalation or Cycle 2 of Dose Confirmation due to treatment-related toxicity; any treatment-related toxicity that causes the participant to discontinue treatment during the DLT observation period, and Gr 5 toxicity.

Original Secondary Outcome Measures  ICMJE
 (submitted: June 5, 2017)
  • Dose Escalation: Area under the plasma concentration time curve (AUC) of MK-1308 at steady state [ Time Frame: pre-dose Cycles 1, 2, 3, 5, 6, 7, 9 and every 4 cycles up to 3 years, postdose (30 min): cycles 1, 2, 3, 5, and 9, Days 8 and 15 of cycles 1, 2, & 3. Cycle = 21 days ]
    AUC is the area under the plot of plasma concentration of drug against time after drug administration and is of particular use in estimating bioavailability of drugs, and in estimating total clearance of drugs. Blood samples will be collected at multiple time points (pre-dose and post-dose) during the Dose Escalation phase to assess the AUC of MK-1308.
  • Dose Escalation: Minimum concentration (Cmin) of MK-1308 at steady state [ Time Frame: pre-dose Cycles 1, 2, 3, 5, 6, 7, 9 and every 4 cycles up to 3 years, postdose (30 min): cycles 1, 2, 3, 5, and 9, Days 8 and 15 of cycles 1, 2, & 3. Cycle = 21 days ]
    Cmin is the minimum or "trough" concentration of a drug observed after its administration and just prior to the administration of a subsequent dose. Blood samples will be collected at multiple time points (pre-dose and post-dose) during the Dose Escalation phase to assess the Cmin of MK-1308.
  • Dose Escalation: Maximum concentration (Cmax) of MK-1308 at steady state [ Time Frame: pre-dose Cycles 1, 2, 3, 5, 6, 7, 9 and every 4 cycles up to 3 years, postdose (30 min): cycles 1, 2, 3, 5, and 9, Days 8 and 15 of cycles 1, 2, & 3. Cycle = 21 days ]
    Cmax is the maximum or "peak" concentration of a drug observed after its administration. Blood samples will be collected at multiple time points (pre-dose and post-dose) during the Dose Escalation phase to assess the Cmax of MK-1308.
  • Dose Confirmation: AUC of MK-1308 at steady state [ Time Frame: pre-dose cycles 1, 2, 3, 4, 5, 6, 8, and every 4 cycles up to 3 years, post-dose (30 min): cycles 1, 2, 3, 4, and 8, Days 8 & 15 in cycles 1, 2, & 3. Cycle = 21 days ]
    AUC is the area under the plot of plasma concentration of drug against time after drug administration and is of particular use in estimating bioavailability of drugs, and in estimating total clearance of drugs. Blood samples will be collected at multiple time points (pre-dose and post-dose) during the Dose Confirmation phase to assess the AUC of MK-1308.
  • Dose Confirmation: Cmin of MK-1308 at steady state [ Time Frame: pre-dose cycles 1, 2, 3, 4, 5, 6, 8, and every 4 cycles up to 3 years, post-dose (30 min): cycles 1, 2, 3, 4, and 8, Days 8 & 15 in cycles 1, 2, & 3. Cycle = 21 days ]

    Cmax is the maximum or "peak" concentration of a drug observed after its administration. Blood samples will be collected at multiple time points (pre-dose and post-dose) during the Dose Confirmation phase to assess the Cmax of MK-1308.
  • Objective Response Rate (ORR) as assessed by investigator based on RECIST 1.1 [ Time Frame: Up to 3 years ]
    ORR is defined as the percentage of participants in the analysis population whose best overall response (BOR) is confirmed complete response (CR) or partial response (PR) based on imaging per RECIST 1.1. According to RECIST 1.1, CR is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR according to RECIST 1.1 is at least a 30% decrease in the sum of diameters (SOD) of target lesions as assessed by the investigator, taking as reference the baseline SOD.
  • ORR as assessed by investigator based on immune-related RECIST (irRECIST) in conjunction with RECIST 1.1 [ Time Frame: Up to 3 years ]
    ORR is defined as the percentage of participants whose best response based on imaging is CR or PR per irRECIST. irRECIST is a modification to RECIST that takes into account unique patterns of atypical response in immunotherapy and enables treatment beyond initial radiographic progression. The irRECIST modification to RECIST is used in conjunction with RECIST 1.1 to determine the BOR. At initial PD by RECIST 1.1, if participant is clinically stable the investigator may continue to treat and scan again ≥4 weeks later to see if PD confirmed. CR is disappearance of all lesions (target, non-target, and new lesions if any had appeared). PR is a decrease of ≥30% in the SOD of target lesions from baseline, with no indication of further progression by non-target or new lesions. BOR during irRECIST portion is the most favorable visit response observed, with no confirmation requirement. BOR for the participant overall is the more favorable of the RECIST 1.1 (pre-PD) and irRECIST (post-PD) BORs.

Descriptive Information
Brief Title  ICMJE Study of Quavonlimab (MK-1308) in Combination With Pembrolizumab (MK-3475) in Advanced Solid Tumors (MK-1308-001)
Official Title  ICMJE A Phase 1 / 2 Open Label, Multi-Arm, Multicenter Study of MK-1308 in Combination With Pembrolizumab in Subjects With Advanced Solid Tumors
Brief Summary This study will assess the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of escalating doses of quavonlimab when used in combination with pembrolizumab in participants with advanced solid tumors.
Detailed Description

After screening, participants are assigned to either the Dose Escalation Phase or Dose Confirmation Phase. The Dose Escalation Phase consists of 3 cohorts and will evaluate available PK and safety data from the first 6 participants of each cohort, including dose limiting toxicities (DLTs). The purpose of the Dose Confirmation Phase is to gather additional safety, tolerability, PK, and preliminary efficacy data of quavonlimab in combination with pembrolizumab. The 5 arms of the Dose Confirmation Phase will include advanced/metastatic non-small cell lung cancer (NSCLC) and second line advanced/metastatic small cell lung cancer (SCLC). In participants who have initial evidence of radiological progressive disease (PD) by modified Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, it will be at the discretion of the investigator whether to continue a participant on study treatment until repeat imaging is obtained.

Protocol Amendment 4 will enroll participants with melanoma in an Efficacy Expansion Cohort. During the Efficacy Expansion Phase, participants will be randomized to receive either quavonlimab in combination with pembrolizumab or quavonlimab monotherapy.

Protocol Amendment 7 will enroll participants in a new cohort (Arm I). During the Coformulation Phase, the safety and PK of a coformulated product of quavonlimab plus pembrolizumab (MK-1308A) will be evaluated in comparison to that of the single, co-administered products given at the same dose and schedule.

Protocol Amendment 8 will enroll participants in 3 new cohorts (Arms J, K, and L). Arm J enrolls participants with refractory melanoma and Arm K enrolls participants in mainland China with relapsed or refractory solid tumor. Arms J and K will receive pembrolizumab/quavonlimab. Arm L enrolls participants in Japan with first-line advanced NSCLC. Participants in Arm L will be divided into 4 sub-cohorts and these sub-cohorts will receive 4 cycles of an indicated chemotherapy PLUS pembrolizumab/quavonlimab.
