In Part 1B, eligible participants with obesity will be randomized to receive two doses of ARO-ALK7 or PBO administered on Day 1 and Day 85. In Part 2, eligible subjects with obesity with and without (T2DM) will be randomized to combined therapy with tirzepatide and ARO-ALK7 (intervention arm) or tirzepatide and PBO (control arm). Tirzepatide will be initiated on Day 15 and administered by subcutaneous (SC) injection weekly. ARO-ALK7 or PBO will be administered by SC injection on Day 1 and Day 85.
