S095029 as Monotherapy and in Combination With Sym021 in Patients With Advanced Solid Tumor Malignancies Followed by an Expansion Part With Triple Combinations in Patients With Metastatic Gastric or Colorectal Cancers

A Phase 1a/1b, Open-label, Multicenter Trial Investigating the Safety, Tolerability, and Preliminary Anti-neoplastic Activity of S095029 (Anti-NKG2A) as Monotherapy and in Combination With Sym021 (Anti-PD-1) in Patients With Advanced Solid Tumor Malignancies Followed by an Expansion Part With Triplet Combinations of S095029 and Sym021 and an Anti-HER2 mAb or Anti-EGFR mAbs (Futuximab/Modotuximab) in Patients With Metastatic Gastric or Colorectal Cancers

Brief summary

The purpose of the study is to investigate the safety, tolerability, and preliminary anti-neoplastic activity of S095029 alone and in combination with Sym021 in patients with advanced solid tumor malignancies followed by an expansion phase of triple combinations. \*The study sponsor has made the decision not to move forward to the expansion part of the study due to strategic considerations, unrelated to any safety issues or concerns. The study will be stopped after completion of dose escalation parts 1a and 1b of the study.

Interventions

S095029 will be administered via IV infusion every 2 weeks. Once the DLT evaluations period at the second dose level is completed and it is deemed as safe, the dose escalation part 1b will be initiated.

DRUGS95029 and Sym021

Sym021 will be administered at a fixed dose of 200mg. S095029 will be administered via IV infusion every 2 weeks. Once the RP2D dose of S95029 in combination with Sym21 is defined, dose expansion will begin.
