Brief Title: Study of Dalutrafusp Alfa (Formerly GS-1423) in Participants With Advanced Solid Tumors
Official Title: A Phase 1a/1b Study of GS-1423, an Anti-CD73-TGFβ-Trap Bifunctional Antibody, as Monotherapy or in Combination With a Chemotherapy Regimen in Subjects With Advanced Solid Tumors
Study ID: NCT03954704
Brief Summary: For Phase 1a Part A, the primary objectives are to assess safety and tolerability and to define the dose limiting toxicity (DLT) and maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) of dalutrafusp alfa (formerly GS-1423) monotherapy in participants with advanced solid tumors. For Phase 1a Part B, the primary objective is to assess safety and tolerability of dalutrafusp alfa monotherapy in participants with advanced solid tumors. For Phase 1b Cohort 1 safety run-in, the primary objective is to assess safety and tolerability and to define the DLT and MTD or RP2D of dalutrafusp alfa in combination with a chemotherapy regimen in participants with advanced gastric or gastroesophageal junction adenocarcinoma. For Phase 1b Cohort 1 post safety run-in, the primary objective is to assess the preliminary efficacy of dalutrafusp alfa in combination with a chemotherapy regimen in participants with advanced gastric or gastroesophageal junction adenocarcinoma, as assessed by the confirmed objective response rate (ORR). For Phase 1b Cohort 2, the primary objective is to assess safety and tolerability of dalutrafusp alfa monotherapy in participants with advanced solid tumors.
