Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs)
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)
|
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)
|
Percentage of Participants Experiencing Treatment-Emergent Laboratory Abnormalities
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)
|
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.
