VK2735

VK2735 hits the same two receptors as tirzepatide, GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide), but Viking Therapeutics is developing it twice over: as a weekly injection and, in a separate programme, as a tablet. An oral version of this class is what much of the field is chasing, because it removes the injection. Every human citation on file is randomised, running from phase 1 through the 13-week VENTURE study in 176 people to two phase 3 trials now enrolling. The scale is worth holding in view: the entire published literature on VK2735 comes to 23 papers, and nothing is approved for anything.

Mechanism

Co-agonism at the GLP-1 and GIP receptors, reducing energy intake through incretin appetite and gastric-emptying pathways.

Figures

Every figure below is replotted by this site from values published in the cited paper's text or tables — the numbers are the study's, the drawing is ours, and the evidence rung on each image is the rung of its source.

Weight change at week 13 — VK2735 VENTURE phase 2 — Week 13, Mean body-weight change at week 13 (%) by treatment
Data: Bays et al. 2026, Obesity (VENTURE phase 2, 13 weeks) · 140 participants on VK2735 and 34 on placebo, adults with obesity or overweight plus one weight-related comorbidity; people with diabetes were excluded. The abstract publishes only the two ends of the dose ladder (2.5 mg = -9.2 kg / -9.1%, 15 mg = -14.6 kg / -14.7%, placebo -1.8 kg / -1.7%), so the intermediate arms are omitted rather than guessed. 93% (130/140) on VK2735 lost 5% or more, vs 12% (4/34) on placebo.

Dosing on file unverified

Titrate to 15 mg/week

Carried from a source that labels it unverified, and reproduced with that label attached. A record of what is reported, not a recommendation. No citation on this page establishes it.

Half-life, storage & sport

Elimination half-life
not on file — A half-life of approximately 170 to 250 hours after single subcutaneous doses is stated, but only in the sponsor's phase 1 press release, which reports no assay, no sampling schedule, no number of subjects and no dispersion. Nothing in it can be read against the evidence ladder. The one peer-reviewed paper on the compound, the phase 2 VENTURE study, carries no pharmacokinetics section at all.

What is circulated not evidence 2

Claims passed around in community guides and vendor copy, recorded because they circulate — not because they are true. Each is shown with the page it was read from and what this record actually holds. Checked 2026-08-24.

  • unverified community data dose occasional nothing on file either way

    Aggregator dose charts circulate a 2.5 mg weekly subcutaneous starting dose for VK2735, reconstituted with 2 mL of bacteriostatic water.

    2.5 mg

    On the record No dosing record exists on file for VK2735; the compound record holds only body-weight reduction, incretin co-agonism research and obesity trial context. Phase 3 arms reported publicly are 7.5, 12.5 and 17.5 mg weekly, so the circulated 2.5 mg start matches no published arm.
