Phase 1/2 Study Exploring the Safety, Tolerability, and Efficacy of INCAGN01876 Combined With Immune Therapies in Advanced or Metastatic Malignancies

An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurred after a participant provided informed consent. Abnormal laboratory values or test results occurring after informed consent constituted AEs only if they induced clinical signs or symptoms, were considered clinically meaningful, required therapy (e.g., hematologic abnormality that required transfusion), or required changes in the study drug(s). A TEAE was defined as any AE either reported for the first time or the worsening of a pre-existing event after the first dose of study medication.

ORR was defined as the percentage of participants with a best overall response of confirmed complete response (CR) or partial response (PR), determined by investigator assessment of radiographic disease assessments per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (v1.1). CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to <10 millimeters (mm). PR: complete disappearance or at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions.

ORR was defined as the percentage of participants with a best overall response of unconfirmed CR or PR, determined by investigator assessment of radiographic disease assessments per RECIST v1.1. CR: disappearance of all target and non-target lesions and no appearance of any new lesions.

ORR was defined as the percentage of participants with a best overall response of unconfirmed CR or PR, determined by investigator assessment of radiographic disease assessments per mRECIST v1.1.

CR: Disappearance of any intratumoral arterial enhancement during in target lesions, disappearance of all non-target lesions, and no appearance of any new lesions. PR: ≥30% of the sum of the diameters of viable portions (enhancement on arterial phase) of target lesions taking as reference the Baseline sum, no new lesions, and no progression of non-target lesions.
