Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs) TEAEs are any AEs with an onset date of on or after the date that ADX and if applicable, nivolumab was first administered and no later than 30 days after permanent discontinuation of ADX, or if applicable, 5 months after permanent discontinuation of nivolumab (whichever is later). First dose date up to 82.4 weeks plus 30 days (or if applicable, up to 5 months after permanent withdrawal of nivolumab)
Primary Percentage of Participants Experiencing Treatment-Emergent Laboratory Abnormalities Treatment-emergent laboratory abnormalities were defined as values that increase at least one toxicity grade from baseline. If the relevant baseline laboratory value was missing, then any abnormality of at least Grade 1 observed within the specified time frame (first dose date up to 82.4 weeks plus 30 days (or if applicable, up to 5 months after permanent withdrawal of nivolumab)) was considered treatment-emergent.Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 was used for assigning toxicity grades to laboratory results for analysis. First dose date up to 82.4 weeks plus 30 days (or if applicable, up to 5 months after permanent withdrawal of nivolumab)
Secondary Cohort 1: Plasma Concentration of Andecaliximab Plasma concentration is defined as the measured drug concentration. Blood samples were drawn at pre-dose and 30 (±15) minutes after infusion on Day 1 of Cycles 2, 3, 5; End of study (EOS) (3 years and 1 month); Cycle 1 only: 30 (±15) minutes after infusion on Day 1; anytime on Day 2, 4, and 8; pre-dose and 30 (±15) minutes post infusion on Day 15. The duration of each cycle for Cohort 1, 2, and 4 was 28 days and for Cohort 3 was 21 days. Infusion duration = 30 to 35 minutes.

Secondary PK Parameter: Cmax of Andecaliximab Cmax is defined as the maximum concentration of drug. Cycle 1 only: 30 (± 15) minutes after the end of infusion on Day 1; anytime on Days 2, 4, and 8; prior to dosing on Day 15 (Cycle length= 28 days) (infusion duration= 30 to 35 minutes)
Secondary PK Parameter: AUClast of Andecaliximab AUClast is defined as the area under the concentration versus time curve to the last measurable concentration of drug from time zero to the last observable concentration. Cycle 1 only: 30 (± 15) minutes after the end of infusion on Day 1; anytime on Days 2, 4, and 8; prior to dosing on Day 15 (Cycle length= 28 days) (infusion duration= 30 to 35 minutes)
Secondary PK Parameter: AUC0-336h of Andecaliximab AUC0-336h is defined as the area under the concentration versus time curve from time zero to time 336 hour. Cycle 1 only: 30 (± 15) minutes after the end of infusion on Day 1; anytime on Days 2, 4, and 8; prior to dosing on Day 15 (Cycle length= 28 days) (infusion duration= 30 to 35 minutes)
Secondary Number of Participants With Positive Anti-Andecaliximab Antibodies Pre-dose on Day 1 of Cycles 1, 2, 3, 5, 7 and every third cycle and anytime at EOT (82.4 weeks) and EOS visit (maximum: 3 years and 1 month) (Each Cycle= 28 days for Cohort 1, 2 and 4; 21 days for Cohort 3)
