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.
