Viking Therapeutics' VK2735 Shows Promising Weight Loss Maintenance in Clinical Trials
Viking Therapeutics announced positive topline results for its injectable GLP-1/GIP dual agonist, VK2735, demonstrating significant weight loss and impressive maintenance of that weight loss in a Phase 1 clinical trial. After 21 weeks, participants receiving 17.5 mg of VK2735 experienced an average body weight reduction of 17.7%. Crucially, the study also evaluated various maintenance dosing options. Following a transition to every-other-week dosing for three months, up to 97% of the weight loss was maintained, compared to 61% for the placebo group. Monthly dosing maintained up to 90% of the weight loss. An exploratory control arm that continued weekly dosing showed a 21.7% weight loss, with Viking suggesting further weight loss could occur with longer-term weekly administration. The safety profile was favorable, with gastrointestinal-related adverse events during the 12-week maintenance period being comparable to placebo, and no moderate or severe nausea reported in the step-down regimens.
