1 PART 1: Phase 1a: ELVN-002 in Combination with Trastuzumab Dose Escalation
For the first dose cohort in Part 1, participants enrolled will receive ELVN-002 orally at 45 mg BID on Days 1-7 followed by 90 mg BID on Days 8 and subsequent days, which is a dose level that is ≤ the maximum tolerated dose (MTD) of ELVN-002 that has been deemed safe and tolerable by the Safety Review Committee in the ongoing monotherapy ELVN-002 study, ELVN-002-001. ELVN-002 will be administered orally starting on C1D1. ELVN-002 dosing will continue daily dosing throughout the DLT evaluation window. The first dose of trastuzumab will be administered IV at 8 mg/kg on C1, D2. Participants who successfully complete the DLT evaluation window will continue to receive ELVN-002 at the assigned daily dose level and trastuzumab in 21-day cycles. Starting with Cycle 2, the trastuzumab dose will be 6 mg/kg, administered IV Day 1 of 21-day cycles. Dosing for both ELVN-002 and trastuzumab will continue until disease progression or one of the protocol-specified stopping criteria has been met.

2 PART 2: ELVN-002 in Combination with Trastuzumab and Chemotherapy Dose Escalation
For the first cohort in Part 2, participants will receive ELVN-002 at a dose at least 1 dose level lower than the highest dose tested in Part 1 that was found to be safe and tolerable combined with trastuzumab. ELVN-002 will be administered daily in combination with a fixed dose of trastuzumab and chemotherapy (CAPEOX, mFOLFOX6, eribulin, capecitabine, or paclitaxel). The first dose of ELVN-002 will be administered on C1D1, the first dose of chemotherapy will be administered on C1D2. The first dose of trastuzumab will be administered on C1D2 unless an alternative dosing schedule has been identified in Part 1. For subsequent dose cycles, trastuzumab and chemotherapy may be administered on the same day (the trastuzumab dose and schedule may be adjusted to allow the chemotherapy and trastuzumab to be administered on the same day consistent with local standard of care). In the setting of a response or stable disease, chemotherapy may be discontinued after 6 cycles or per institutional standard of care and the participant may continue to receive ELVN-002 and trastuzumab until progression or other stopping criteria are met For CAPEOX and mFOLFOX6, oxaliplatin may be discontinued due to neurotoxicity or per institutional standard of care and the participant may continue to receive capecitabine or 5-FU/LCV in addition to the ELVN-002 and trastuzumab
