Study summary

This study is one of two planned Phase 3 studies to support the weight management indication for VK2735 Oral in obese (BMI ≥ 30 kg/m2) or overweight (BMI ≥ 27 kg/m2) adults with Type 2 Diabetes Mellitus.

Read the detailed description

This is a Phase 3, multicenter, 68-week randomized, double-blind, placebo-controlled, parallel arm study that will evaluate the weight loss efficacy as well as safety, tolerability, pharmacodynamic effects, and pharmacokinetics of VK2735 oral formulation in adults with Type 2 Diabetes Mellitus (T2DM) who are obese or overweight.

Inclusion criteria

  1. Age ≥18 years of age at the time of signing the informed consent.
  2. Body mass index (BMI) ≥ 27 kg/m2
  3. Have Type 2 Diabetes Mellitus according to the American Diabetes Association (See Section 12.5), with HbA1c ≥ 7% to ≤ 11% at screening, on stable therapy for the last 3 months prior to Screening. Participants with HbA1c between 6.5%-6.9% or 11.0%-11.5% are allowed to have a single HbA1c retesting to confirm eligibility. Type 2 Diabetes Mellitus may be treated with diet/exercise alone or any oral glycemic-lowering agent (as per local labeling), EXCEPT for amylin analogues or dipeptidyl peptidase 4 (DPP-4) inhibitors or GLP-1R agonists or dual GLP-1/ glucose-dependent insulinotropic polypeptide (GIP) receptor agonists.

Exclusion criteria

Exclusion Criteria:

  1. History of or current clinically significant medical disorder that, in the opinion of the Investigator, does not support study participation
  2. Self-reported body weight change of 5% or more within 3 months of screening
  3. Have a prior or planned surgical treatment for obesity such as a gastric sleeve, lap band or any form of bariatric surgery (except for liposuction or abdominoplasty if performed >1 year prior to screening)
  4. Have or plan to have endoscopic and/or device-based therapy for obesity or have had device removal within the last 6 months prior to screening (such as mucosal ablation, gastric artery embolization, intragastric balloon, duodenal-jejunal endoluminal line)
  5. Have Type 1 Diabetes Mellitus, history of ketoacidosis or hyperosmolar state/coma or any other types of diabetes except Type 2 Diabetes Mellitus (T2DM)
  6. Have had 1 or more episodes of severe hypoglycemia and/or 1 or more episode of hypoglycemia unawareness within 6 months of screening

    • Note: Severe hypoglycemia episodes should be considered when severe cognitive impairment requiring the assistance of another person occurs and the administration of carbohydrate, glucagon, or other resuscitative actions are required. Blood glucose (BG) measurements may not be available during such an event, but neurological recovery attributable to the restoration of BG to normal is considered sufficient evidence that the event was induced by a low BG concentration. If BG measurements are available, the levels associated with severe hypoglycemia are BG \< 54 mg/dL.
  7. Have at least 2 confirmed fasting self-monitoring blood glucose (SMBG) values > 270 mg/dL (on 2 non-consecutive days) within 4 weeks prior to randomization
  8. Have non-proliferative diabetic retinopathy that requires acute treatment OR diabetic macular edema OR proliferative diabetic retinopathy identified during a dilated fundoscopy examination performed within 3 months of screening. Please see Section 7.6.
  9. Personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia type 2 (MEN2)
  10. History of acute or chronic pancreatitis
  11. Thyroid disease that is not controlled (Thyroid stimulating hormone (TSH) outside normal range by central lab at screening; one repetition during screening is allowed). Participants with previous history of partial/total thyroidectomy or hypothyroidism may be included, provided their hormone replacement dose has been stable for 3 months prior to screening.

ElapsedEstimatedEstimated, not yet reachedDate before it movedWhere the date was before it movedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Nov 2026; primary completion for Oct 2028, 23 months later.

Of 24 phase 3 interventional studies under Weight Loss, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 20 and three quarters within 29. This study's planned 23 months is close to that.

Start moved once since we started tracking on Sep 25, 2026: Oct 2026 → Nov 2026, on Oct 16, 2026.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
