This is an open-label, multicenter, Phase 1/2 study of RAS(ON) inhibitors in combination with ivonescimab with or without other anti-cancer agents in adults with advanced or metastatic solid tumors with a RAS mutation to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary clinical activity. The study consists of three arms: Arm A:daraxonrasib in combination with ivonescimab; Arm B: elironrasib in combination with ivonescimab; and Arm C: zoldonrasib in combination with ivonescimab. All arms consist of two parts: Part 1- dose exploration and Part 2- dose expansion. Part 1 dose exploration will explore the safety and tolerability of individual RAS(ON) inhibitors in combination with ivonescimab. Part 2 dose expansion will explore the safety, tolerability, and antitumor activity of the individual RAS(ON) inhibitors with ivonescimab +/- anti-cancer therapies.
