Part A: GS-5319 Monotherapy Dose EscalationEXPERIMENTALParticipants will receive escalating doses of GS-5319 monotherapy, until disease progression, or until the participants meets other study drug discontinuation criteria as specified in protocol or up to 105 weeks, whichever occurs first to determine the recommended dose for dose expansion phase.
Part B: GS-5319 Monotherapy Dose ExpansionEXPERIMENTALParticipants will be enrolled based on the selected indications to receive GS-5319 monotherapy at the recommended dose during the monotherapy dose expansion phase.
Part C: GS-5319 Monotherapy Dose OptimizationEXPERIMENTALParticipants will be randomized based on the selected indications to receive GS-5319 monotherapy at one of the recommended doses during the monotherapy dose optimization phase.
Part D: GS-5319 Combination Therapy Dose EscalationEXPERIMENTALParticipants will receive escalating doses of GS-5319 as combination therapy with carboplatin, pemetrexed, pembrolizumab, until disease progression, or until the participants meets other study drug discontinuation criteria as specified in protocol or up to 105 weeks, whichever occurs first to determine the recommended dose for dose escalation phase.
