Other Names:
  • MGA012
  • INCMGA00012




Primary Outcome Measures :
  1. Overall Response Rate (ORR) [ Time Frame: Cycle 1 day 1, and every 4 weeks throughout the study, up to approximately 24 months. ]
    Defined as Complete Response (CR),- Disappearance of all target lesions; Partial Response (PR)->=30% decrease in the sum of the longest diameter (LD) of target lesions from baseline; Overall Response (OR) = CR + PR, as per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions as assessed by independent central radiographic review (ICR)


Secondary Outcome Measures :
  1. Duration of Response [ Time Frame: Up to approximately 3 years ]
    The time measurement from initial objective response Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions), as per RECIST v1.0, until the first date that disease progression is determined by ICR or death.

  2. Disease Control Rate [ Time Frame: Up to approximately 3 years ]
    The number of participants with a confirmed overall response of CR, PR, or SD, as per RECIST 1.1, at any postbaseline visit until the first PD or start of new anticancer therapy.

  3. Progression-free Survival [ Time Frame: Up to approximately 3 years ]
    According to RECIST 1.1, PFS is defined as the length of time from initial infusion of study drug until the earliest date of disease progression, determined by ICR, or death due to any cause, if occurring sooner than progression.

  4. Overall Survival [ Time Frame: Up to approximately 3 years ]
    Overall survival is defined as the time in months between the first dose date (Day 1) and the date of death due to any cause.

  5. Number of Treatment-emergent Adverse Events [ Time Frame: Up to approximately 3 years ]
    Adverse events reported for the first time or worsening of a pre-existing event after first dose of study treatment.

  6. Cmax of INCMGA00012 [ Time Frame: Preinfusion on Day 1 of Cycles 1, 2, 4, 6, and 7 and 10 minutes and 4 hrs post-infusion on D1C1 and D1C6 ]
    Maximum observed plasma concentration

  7. Tmax of INCMGA00012 [ Time Frame: Preinfusion, 10 minutes post-infusion D1C6 ]
    Time to maximum concentration.

  8. Cmin of INCMGA00012 [ Time Frame: Preinfusion on Day 1 of Cycles 1, 2, 4, 6, and 7 and 10 minutes and 4 hrs post-infusion on D1C1 and D1C6 ]
    Minimum observed plasma concentration over the dose interval.

  9. AUC0-t of INCMGA00012 [ Time Frame: Preinfusion on Day 1 of Cycles 1, 2, 4, 6, and 7 and 10 minutes post-infusion and 4 hrs post-infusion on D1C1 and D1C6 ]
    Area under the plasma concentration-time curve from time = 0 to the last measurable concentration at time = t. Cycle 1 and Cycle 6: Day 1 predose and 10 min and 4 h after infusion Cycles 2, 4, and 7: Day 1 predose
