Nivolumab (BMS-936558; MDX-1106) in Combination With Sunitinib, Pazopanib, or Ipilimumab in Subjects With Metastatic Renal Cell Carcinoma (RCC) (CheckMate 016)

Safety assessments by treatment arm and dose level were based on incidence of AEs, and the incidence of serious adverse events (SAEs). AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Treatment-related=having certain, probable, possible, or missing relationship to study drug. Grade (Gr) 1=Mild, Gr 2=Moderate, Gr 3=Severe, Gr 4= Potentially Life-threatening or disabling.

BOR was defined as the best response designation over the study as a whole, recorded between the date of first dose of study medication and the date of objectively documented progression per RECIST 1.1 criteria or the date of subsequent anti-cancer therapy, whichever occurred first.

CR = Disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to < 10 mm. PR = At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. PD = At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered progression. SD = Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

ORR was defined as the proportion of participants who achieved a BOR of either complete response (CR) or partial response (PR) in the population of interest.

CR = Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. PR = At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

DOR was computed for participants with BOR of CR or PR only, and defined as the time between the date of first documented objective response and the date of the first subsequent disease progression or death. Participants who remained alive and had not progressed were censored on the last tumor assessment date (prior to subsequent cancer therapy).

Rate of PFS at week 24 was defined as the proportion of participants remaining progression free or surviving at 24 weeks, calculated by the product-limit method (Kaplan-Meier estimate) which took into account censored data. Participants who did not have any on-study tumor assessment and did not die were censored on the date of first dose of study medication.

PFS was defined as the time from the date of first dose of study medication to the date of first disease progression or death. Participants who did not have any on-study tumor assessment and did not die were censored on the date of first dose of study medication.
