This is a Phase 1b, open-label, multicenter master protocol evaluating safety, tolerability, and antitumor activity of ERAS-007 or ERAS-601 in combination with other cancer therapies in study participants with advanced NSCLC. The study will commence with the following dose escalation cohorts: ERAS-007 plus osimertinib in study participants with advanced NSCLC harboring epidermal growth factor receptor-sensitizing mutation(s) (EGFRm); ERAS-007 or ERAS-601 plus sotorasib in study participants with advanced NSCLC harboring Kirsten rat sarcoma G12C mutation (KRAS G12Cm). Dose expansion will follow and will evaluate ERAS-007 or ERAS-601 drug combinations administered at the RD identified from each respective dose escalation cohort in study participants with advanced EGFRm or KRAS G12Cm NSCLC.
To evaluate the safety and tolerability of escalating doses of ERAS-007 or ERAS-601 in combination with other cancer therapies in study participants with advanced non-small cell lung cancer (NSCLC).~To determine the Maximum Tolerated Dose (MTD) and/or Recommended Dose (RD) of ERAS-007 or ERAS-601 administered in combination with other cancer therapies.~To evaluate the antitumor activity of ERAS-007 or ERAS-601 in combination with other cancer therapies.~To evaluate the PK profiles of ERAS-007 or ERAS-601 and other cancer therapies when administered in combination.
