Viking Therapeutics VK2735 Oral Phase 2 VENTURE-Oral Full 13-Week Data (May 12 ECO): 12.2% Mean Weight Loss (26.6 lbs) Dose-Dependent, Week 1 Onset
Viking Therapeutics presented full 13-week Phase 2 VENTURE-Oral data at ECO 2026 May 12 in Istanbul: once-daily oral VK2735 produced statistically significant, dose-dependent mean weight loss up to 12.2% (26.6 lbs) over 13 weeks with placebo-adjusted significance starting at Week 1. The favorable tolerability profile and rapid early onset of effect support Viking's Q4 2026 plan to initiate a Phase 3 trial of the oral formulation following positive FDA feedback. The data complements the Phase 3 VANQUISH-1 subcutaneous program (4,650 patients enrolled November 2025) and VANQUISH-2 in T2D+obesity (~1,000 patients, enrollment completed March 26, 2026). VK2735's dual GLP-1/GIP mechanism puts it in direct comparison with tirzepatide and the next-generation Mounjaro/Zepbound franchise.
