Required: ROS1 wild-type

Has documented negative test results for...ROS1 actionable genomic alterations

Required: NTRK1 wild-type

Has no known actionable genomic alterations in NTRK, BRAF, RET, MET, or other actionable oncogenic drivers with locally approved therapies

Required: NTRK2 wild-type

Has no known actionable genomic alterations in NTRK, BRAF, RET, MET, or other actionable oncogenic drivers with locally approved therapies

Required: NTRK3 wild-type

Has no known actionable genomic alterations in NTRK, BRAF, RET, MET, or other actionable oncogenic drivers with locally approved therapies

Required: BRAF wild-type

Has no known actionable genomic alterations in NTRK, BRAF, RET, MET, or other actionable oncogenic drivers with locally approved therapies

Required: Stage IIIB, IIIC, IV

Performance status

ECOG 0–1(Restricted strenuous activity)

Prior therapy

Max 0 prior lines

Cannot have received: anti-pd-1/pd-l1/pd-l2 or co-inhibitory t-cell receptor therapy

Cannot have received: enhancer of zeste homolog inhibitor

Lab requirements

Cardiac function

No uncontrolled or significant cardiovascular disease, including mean QTcF >470 ms, recent MI or angina, NYHA Class 3 or 4 CHF, or uncontrolled hypertension
