Clinical Trial Outcome Measures

Primary Measures

  • Objective Response Rate (ORR) Using Immune RECIST (iRECIST) Criteria
    • Time Frame: 10 months
    • ORR is defined as the number of patients achieving a complete response (CR) or partial response (PR) based on immune Response Evaluation Criteria in Solid Tumors (iRECIST) at any time during the study. CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions, progressive disease (PD) is >20% increase in sum of diameters of target lesions, stable disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions.

Secondary Measures

  • Overall Response Rate (ORR) Using RECIST 1.1 Criteria
    • Time Frame: 10 months
    • Objective Response Rate (ORR) is defined as the number of patients achieving a complete response (CR) or partial response (PR) based on RECIST 1.1 criteria. CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions. Subjects who discontinue due to toxicity or clinical progression prior to post-baseline tumor assessments will be considered as non-responders.
  • Number of Participants Experiencing Grade 3 or Above Drug-related Toxicities
    • Time Frame: 13 months
    • Defined using NCI CTCAE v5.0
