Frequently asked questions about VK2735

What is VK2735 used for?

VK2735 is an investigational small molecule being developed for weight loss, including weight management in adults with type 2 diabetes mellitus. It is in Phase 3 clinical development and is not yet approved for any indication. The program includes separate Phase 3 studies in weight management and in weight management with type 2 diabetes.

What does VK2735 target?

VK2735 targets the GLP-1 and GIP receptors. Both are receptors involved in metabolic signaling, and the drug is designed as a small molecule that acts on these two receptor targets. This dual receptor activity is the basis for its development in weight loss and weight management in adults with type 2 diabetes.

Who is developing VK2735?

VK2735 is being developed by Viking Therapeutics, Inc., which trades under the ticker VKTX. Viking Therapeutics is the sponsor of the Phase 3 clinical program evaluating the drug for weight loss, including studies in adults with type 2 diabetes mellitus.

What phase is VK2735 in?

VK2735 is in Phase 3 clinical development. It is an investigational drug and has not been approved by the FDA for any indication. The Phase 3 program includes trials that are active and not recruiting as well as trials that are not yet recruiting, with a total of seven trials across completed and ongoing stages.

What clinical trials is VK2735 in?

Phase 3 trials of VK2735 include NCT07104500 and NCT07104383, both active and not recruiting, and NCT07868939 (SUNRISE 2) and NCT07868835 (SUNRISE 1), both not yet recruiting. The program totals seven trials, four active and three completed, with 7,268 participants enrolled overall.

Is VK2735 the same as VK2735 Oral?

Yes, VK2735 Oral is another name for VK2735. Both refer to the same investigational small molecule developed by Viking Therapeutics for weight loss. The oral designation reflects the oral route of administration used in the Phase 3 weight management studies, including the SUNRISE 1 and SUNRISE 2 trials.
