Viking Launches Phase 2 Study of Oral VK2735 Maintenance Dosing
San Diego – October 06, 2026 -- Viking Therapeutics (NASDAQ: VKTX) has initiated Part 2 of a maintenance dosing study for VK2735, its dual GLP-1/GIP receptor agonist, testing oral tablet regimens alongside subcutaneous options to sustain weight loss after initial treatment.
Trial enrolls 195 obese adults to test five maintenance pathways
The randomized, double-blind, placebo-controlled study will enroll approximately 195 adults with obesity (BMI ≥30 kg/m2). All participants first receive 21 weeks of weekly subcutaneous VK2735 or placebo before transitioning to one of five maintenance arms: daily oral doses, weekly oral doses, monthly subcutaneous doses, every-other-week subcutaneous doses, or placebo. The study runs through Week 33, tracking safety, tolerability, pharmacokinetics, and body weight change from baseline and from Week 21.
