If participant received major surgery, then they must have recovered adequately from toxicities and/or complications from the intervention before starting study treatment. 20.

Current use of prohibited medication as noted in Section 6.8.3. 23. Any condition that would, in the investigator's judgment, interfere with full participation in the study, including administration of study treatment and attending required study visits; pose a significant risk to the participant; or interfere with interpretation of study data. 24. Participants who are known to be HIV-positive. 25. History or presence of an abnormal ECG that, in the investigator's opinion, is clinically meaningful. Average QTc interval > 480 milliseconds is excluded (corrected by Fridericia or Bazett formula). 26. History of a gastrointestinal condition (eg, inflammatory bowel disease, Crohn's disease, ulcerative colitis) that may affect oral drug absorption. 27. Exclusion criteria specific to a group receiving combination therapy. a. Participants enrolled in the epacadostat combination (Group C only): − History of serotonin syndrome after receiving 1 or more serotonergic drugs. b.

E.5.2 | Secondary end point(s) |
Group A (INCMGA00012 monotherapy): • DOR, defined as the time from the first documented objective response (CR or PR) according to RECIST v1.1 (as determined by ICR) until disease progression or death due to any cause. • DCR, defined as the proportion of participants with CR, PR, or SD (as determined by ICR) as best response. • PFS, defined as the time from the first dose of study treatment until disease progression (as determined by ICR) or death due to any cause. • OS, defined as the time from the first dose of study treatment until death due to any cause. All other groups: • ORR, defined as the proportion of participants having a CR or PR according to RECIST v1.1 (as determined by the investigator). Safety and tolerability will be assessed by monitoring the frequency and severity of AEs and SAEs as well as laboratory test results. |
