Study Summary

OKI-219-101 is a Phase 1a/1b, open-label, multicenter, dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PDx), and efficacy of OKI-219 as monotherapy and in combination with other anti-cancer drugs. Phase 1a (Part A) will investigate escalating doses of OKI-219 monotherapy, and Phase 1b will investigate OKI-219 (at a tolerated dose determined in Part A) in combination with fulvestrant (Part B), trastuzumab and tucatinib (Part C), atirmociclib (Part D), and ribociclib and fulvestrant (Part E). Participants will continue to receive study treatment until disease progression, intolerable toxicity, or other study treatment withdrawal criteria are met.
