GH21 Combined With D-1553 in KRAS G12C Mutant Advanced Solid Tumors

Phase 1
Not yet recruiting
Conditions
Locally Advanced or Metastatic Solid Tumors Harboring KRAS G12C Mutation
Interventions
Registration Number
NCT06435455
Lead Sponsor
Suzhou Genhouse Bio Co., Ltd.
Brief Summary

This s a multi-center, open-label phase Ib/II study to evaluate the safety, tolerability, pharmacokinetics, and efficacy of GH21 combined with D-1553 in patients with advanced or metastatic solid tumors harboring KRAS G12C mutation.

Detailed Description

This study includes 2 parts: dose escalation(Phase Ib) and dose expansion (Phase II). The objective of the dose escalation part is to evaluate the safety, tolerability and pharmacokinetics of GH21 in combination with D-1553 in patients with advanced solid tumors harboring KRAS G12C mutation and to determine the RP2D for the combination therapy. In the dose expansion part, preliminary efficacy and safety of the combination therapy at the RP2D will be further explored in patients with specific cancer harboring KRAS G12C mutation.
