Study Endpoints
Primary Endpoints
Phase Ia: Number of Participants with One or More Treatment Emergent Adverse Events (TEAEs), Serious Adverse Event(s) (SAEs), and Adverse Event(s) (AEs)
Up to Approximately 48 Months or 4 Years

A summary of TEAEs, SAEs, and AEs regardless of causality, will be reported in the Reported Adverse Events module

Phase 1a: To determine the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of LY4050784
Up to Approximately 48 Months or 4 Years

Number of participants with dose-limiting toxicities (DLTs)

Phase 1b: To assess the antitumor activity of LY4050784 Monotherapy: Overall response rate (ORR)
Up to Approximately 48 Months or 4 Years

ORR per investigator assessed Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST 1.1)

Phase 1b (Dose optimization only): To confirm the RP2D/optimal dose based on safety and efficacy of LY4050784
Up to Approximately 48 Months or 4 Years

A summary of TEAEs, SAEs, and AEs regardless of causality, will be reported in the Reported Adverse Events module, ORR and Duration of Response (DOR) per Investigator

Phase 1b (Combination cohorts/Part C): To assess the safety and tolerability of LY4050784 when administered in combination with other anticancer agents
Up to Approximately 48 Months or 4 Years

A summary of TEAEs, SAEs, and AEs regardless of causality, will be reported in the Reported Adverse Events module
