Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Age ≥18 years of age at the time of signing the informed consent.
- Body mass index (BMI) ≥ 27 kg/m2
- 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.
Who cannot join
- History of or current clinically significant medical disorder that, in the opinion of the Investigator, does not support study participation
- Self-reported body weight change of 5% or more within 3 months of screening
- 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)
- 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)
- Have Type 1 Diabetes Mellitus, history of ketoacidosis or hyperosmolar state/coma or any other types of diabetes except Type 2 Diabetes Mellitus (T2DM)
- Have had 1 or more episodes of severe hypoglycemia and/or 1 or more episode of hypoglycemia unawareness within 6 months of screening
Show all 12Show fewer
- 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.
- 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
- 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.
- Personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia type 2 (MEN2)
- History of acute or chronic pancreatitis
- 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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing VK2735 Oral in people with Weight Loss, run by Viking Therapeutics, Inc..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Hubert Chen, MD (8587044660, clinicaltrials@vikingtherapeutics.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percent change in body weight for participants with type 2 diabetes mellitus receiving VK2735 orally once daily (time frame: 68 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026.
