Overview
This study is to evaluate the safety, tolerability, and PK profiles of Elironrasib and Daraxonrasib as monotherapies and combination therapy in patients with KRAS G12C-mutated solid tumors.
Description
This is an open-label, multicenter, Phase 1b/2 study evaluating elironrasib and daraxonrasib, administered as monotherapy and in combination, in patients with advanced KRAS G12C-mutated solid tumors to determine the maximum tolerated dose (MTD), identify the recommended Phase 2 dose and schedule (RP2DS), and preliminarily assess antitumor activity.
The study includes a Phase 1b dose escalation and expansion of combination therapy, followed by a Phase 2 evaluation of the selected RP2DS as monotherapy and combination therapy to further assess safety and antitumor activity.
Eligibility
Inclusion Criteria:
- 18 years of age

- NSCLC, previously treated with immunotherapy, chemotherapy, and KRAS G12C (OFF) inhibitors ii. Solid tumors, previously treated, naïve to KRAS G12C (OFF) inhibitors.
- ECOG performance status 0 or 1
- Adequate organ function
Exclusion Criteria:
- Primary central nervous system (CNS) tumors
- Active brain metastases
- Known impairment of GI function that would alter the absorption
