SAN DIEGO , Feb. 11, 2026 /PRNewswire/ -- Viking Therapeutics, Inc. (Viking) (Nasdaq: VKTX), a clinical-stage biopharmaceutical company focused on the development of novel therapies for metabolic and endocrine disorders, today announced its financial results for the fourth quarter and year ended December 31, 2025, and provided an update on its clinical pipeline and other corporate developments.

Highlights from the Quarter and Year Ended December 31, 2025, and Other Recent Events:

"The past year was an exceptional year for Viking marked by rapid progress across our obesity portfolio," stated Brian Lian, Ph.D., chief executive officer of Viking.  "In June, the company initiated the Phase 3 VANQUISH clinical program evaluating the subcutaneous formulation of VK2735, a dual agonist of the GLP-1 and GIP receptors, for obesity.  We announced completion of enrollment in VANQUISH-1 in the fourth quarter and expect to complete enrollment in VANQUISH-2 later this quarter.  In 2025 the company also announced positive top-line results from its Phase 2 VENTURE-Oral dosing trial of the tablet formulation of VK2735 in obesity.  Following feedback from an end-of-Phase 2 meeting with the FDA, we plan to advance oral VK2735 into Phase 3 development in 3Q26.  Based on exciting early data suggesting the potential for maintenance dosing with VK2735, in the fourth quarter we initiated a study designed to evaluate monthly subcutaneous dosing, daily oral dosing, and weekly oral dosing.  This trial will provide data to potentially further differentiate VK2735 as the only dual agonist molecule with the potential to dose monthly or to allow transition from subcutaneous to oral administration for weight maintenance.  This study is fully enrolled and we look forward to announcing the results in the third quarter of 2026.  We also expect to file an IND for our novel amylin agonist this quarter, expanding our obesity franchise.  During the year Viking continued building the foundation to support commercial activities by entering into a comprehensive manufacturing and supply agreement for VK2735 and expanding our commercial depth to prepare for success.  Throughout these activities we have continued to exercise fiscal discipline and maintain a strong balance sheet, which will allow us to meet key milestones in the quarters ahead.  We expect 2026 to be another exciting and productive year and look forward to providing updates along the way."

Pipeline and Recent Corporate Highlights

• Phase 3 VANQUISH Trials for Subcutaneous VK2735 in Obesity Ongoing; VANQUISH-1 Fully Enrolled Ahead of Schedule, VANQUISH-2 Nearing Full Enrollment. VK2735 is a wholly owned long-acting dual agonist of the glucagon like peptide-1, or GLP-1 receptor, and the glucose dependent insulinotropic polypeptide, or GIP receptor, for the potential treatment of obesity and other metabolic disorders.
  
  The company previously announced positive top-line data from its Phase 2 VENTURE study of VK2735 in adults with obesity. This study demonstrated statistically significant reductions in mean body weight from baseline, ranging up to 14.7% after 13 weekly doses. The VENTURE study also showed VK2735 to be safe and well tolerated through 13 weeks of dosing, with the majority of treatment emergent adverse events characterized as mild or moderate. Adverse events generally occurred early in the course of treatment, resolved quickly, and were primarily related to the expected gastrointestinal effects resulting from activation of the GLP-1 receptor.
  
  In June 2025, following an end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA), the company initiated the VANQUISH Phase 3 registration program. The VANQUISH program consists of two trials evaluating VK2735: one in adults with obesity (VANQUISH-1) and one in adults with obesity and type 2 diabetes (VANQUISH-2). Each study is a randomized, double-blind, placebo-controlled, multicenter trial designed to assess the efficacy and safety of VK2735 administered by subcutaneous injection once weekly for 78 weeks. The VANQUISH-1 study was designed to target enrollment of approximately 4,500 patients, and the VANQUISH-2 study is targeting enrollment of approximately 1,100 patients. Participants in each of these trials will be randomized to weekly VK2735 treatment arms of 7.5 mg, 12.5 mg, 17.5 mg, or placebo.
  
  The primary endpoint of the VANQUISH trials is the percent change in body weight from baseline after 78 weeks of treatment for participants receiving VK2735 as compared to placebo. Secondary and exploratory endpoints will evaluate a range of additional safety and efficacy measures, including the percentage of patients who achieve ≥5%, ≥10%, ≥15% and ≥20% body weight reduction. Each study will also include a one-year extension allowing participants the opportunity to continue receiving treatment following completion of the primary dosing period, including patients receiving placebo during the initial portion of trial.
  
  In November 2025 the company announced completion of enrollment in the VANQUISH-1 study. The trial enrolled more than 4,500 patients, exceeding the original enrollment target, ahead of schedule. The company believes the rapid pace of enrollment observed in the VANQUISH program demonstrates the significant continued enthusiasm among investigators, clinicians and patients for the VK2735 program. Enrollment in the VANQUISH 2 study is continuing and the company expects to complete enrollment in 1Q26.
  
  
• Phase 2 VENTURE Data Highlighted in Presentations at ObesityWeek 2025 and Published in Peer-Reviewed Journal, Obesity. The effects of weekly VK2735 on certain cardiometabolic parameters that were observed in the VENTURE study were highlighted in a poster presentation at the 2025 ObesityWeek conference in November. The results demonstrated that patients receiving VK2735 experienced improvements in metabolic syndrome and prediabetic status compared with patients receiving placebo. In addition, in January 2026 the full results of the VENTURE study were the subject of a publication titled, "Weekly Subcutaneous VK2735, a GIP/GLP-1 Receptor Dual Agonist, for Weight Management: Phase 2, Randomized, 13-Week VENTURE Study," published in Obesity, the peer-reviewed journal of The Obesity Society. This publication can be accessed online at: https://onlinelibrary.wiley.com/doi/10.1002/oby.70106. The ObesityWeek presentation and Obesity publication highlight VK2735's promising efficacy, tolerability, and broader impact on improved cardiometabolic status after a relatively short 13 week treatment window.
  
  
• Oral VK2735 to Advance into Phase 3 Trials, Expected to Begin 3Q26. In addition to the development of a subcutaneous formulation, Viking is also advancing an oral tablet formulation of VK2735. The company believes the availability of both an oral and an injectable formulation is an important factor differentiating VK2735 from competitive agents, as no other dual or triple agonist is currently available in both formulations. The successful development of both a tablet and a subcutaneous injection may represent an attractive option for those who prefer to initiate treatment with an oral therapy, or for those seeking to maintain the weight loss they have already achieved with an injectable therapy. Using the same active ingredient in both formulations may reduce the risk of unexpected side effects compared with switching between therapies that do not share the same active agent.
  
  The company's prior Phase 1 and Phase 2 studies evaluating the oral tablet formulation of VK2735 successfully achieved their objectives. Viking's Phase 1 study demonstrated dose-dependent reductions in mean body weight from baseline, ranging up to 8.2% after 28 days of daily dosing. The initial weight loss observed in the Phase 1 study also showed encouraging durability, with up to 8.3% reduction in body weight from baseline observed at follow-up visits through Day 57, four weeks after the last dose was administered. The study demonstrated encouraging safety and tolerability through 28 days of once-daily dosing, at doses up to and including 100 mg, with the majority of observed treatment emergent adverse events (TEAEs) reported as mild or moderate, with most reported as mild.
  
  The company's Phase 2 VENTURE-Oral Dosing study also successfully achieved its primary and secondary endpoints, with impressive reductions in body weight observed, as well as an encouraging safety and tolerability profile. This study was a randomized, double-blind, placebo-controlled multicenter trial designed to evaluate the safety, tolerability, pharmacokinetics and weight loss efficacy of VK2735 dosed as an oral tablet once daily for 13 weeks. The primary endpoint of the study was the percent change in body weight from baseline after 13 weeks of treatment.
  
  In the third quarter of 2025, the company announced positive top-line results from the VENTURE-Oral Dosing study, with statistically significant reductions in body weight observed, along with promising safety and tolerability. Participants receiving once daily doses of the oral tablet formulation of VK2735 demonstrated reductions in mean body weight after 13 weeks, ranging up to 12.2% from baseline. Weight loss was progressive at all doses through the course of the study. Statistically significant differences compared to both baseline and placebo were observed for all doses >15 mg starting at Week 1 and continuing throughout the 13-week treatment period. All doses of VK2735 >15 mg also demonstrated statistically significant differences relative to placebo on the key secondary endpoint assessing the proportion of subjects demonstrating at least 5% and 10% weight loss. Up to 97% of subjects in the VK2735 treatment groups achieved ≥5% weight loss, compared with 10% for placebo, and up to 80% of subjects in VK2735 treatment groups achieved ≥10% weight loss, compared with 5% for placebo.
  
  The VENTURE-Oral Dosing study included an exploratory dosing cohort designed to assess weight loss maintenance. In this cohort, participants were rapidly titrated to 90 mg daily doses. After four weeks of daily dosing at 90 mg, participants were down-titrated to 30 mg daily doses and maintained at 30 mg daily for seven weeks. Weight loss in this cohort was shown to be rapid and progressive through the 90 mg treatment period and was further extended following the transition to 30 mg daily doses. The observed results suggest that effective weight maintenance may be possible at doses <30 mg daily.
  
  The oral tablet formulation of VK2735 also demonstrated encouraging safety and tolerability following 13 weeks of once-daily dosing. Among subjects receiving VK2735, 98% of reported drug-related TEAEs were categorized as mild or moderate in severity. The majority (99%) of gastrointestinal (GI)-related TEAEs were also reported as mild or moderate. Consistent with the results of the subcutaneous Phase 2 trial, GI-related adverse events were generally observed early in treatment, with decreasing frequency upon repeat dosing.
  
  In December 2025, Viking held an end-of-Phase 2 meeting with the FDA to discuss potential next steps for oral VK2735. Based on feedback from the agency, the company plans to advance oral VK2735 into Phase 3 development for obesity, expected to begin in 3Q26.
  
  
• VK2735 Phase 1 Maintenance Dosing Study Fully Enrolled; Data Expected 3Q26. Based on VK2735's extended plasma half-life and the availability of both injectable and oral dosage forms, the company is evaluating a range of novel dosing regimens for both the induction and the long-term maintenance of weight loss. Providing flexible dosing options for long-term therapy may improve treatment persistence following achievement of individual weight loss goals. As mentioned above, Viking believes that VK2735 is differentiated from currently available obesity treatments as it represents the only option utilizing the same dual-acting GLP-1 and GIP co-agonist molecule in both a subcutaneous and an oral formulation. Providing patients the option to remain on the same active compound throughout their treatment may reduce the potential for undesired side effects compared with options that involve switching between different therapeutic agents. The company believes this may lead to improved adherence to therapy and increase the probability of realizing the long-term benefits of weight loss such as reduced cardiovascular risks, improved physical function and increased quality of life.
  
  In October 2025, Viking initiated a Phase 1 study designed to explore the feasibility of various VK2735 maintenance dosing regimens utilizing both the oral tablet and the subcutaneous formulation. This trial is a randomized, double-blind, placebo-controlled trial in approximately 180 adults with obesity (BMI ≥30 kg/m²). All participants will receive initial weekly subcutaneous doses of VK2735 or placebo for 19 weeks. Following Week 19, participants are transitioned to a range of VK2735 maintenance dosing regimens including weekly, every other week, and monthly subcutaneous dosing, as well as daily oral dosing, weekly oral dosing, or placebo. The objectives of the study are to evaluate the safety, tolerability, and pharmacokinetic (PK) profile of VK2735 under these various dosing regimens. Exploratory endpoints will assess change in body weight from baseline, as well as change in body weight from Week 19 to the end of the study at Week 31.
  
  In January 2026, Viking announced completion of enrollment in the maintenance dosing study. The company expects to report the results of the study in 3Q26.
  
  
• IND for Dual Amylin and Calcitonin Receptor Agonist (DACRA) Planned for 1Q26. The amylin and calcitonin receptors play an important role in regulating food intake and metabolic control, making them potential therapeutic targets for obesity. Viking believes that dual activation of the amylin and calcitonin receptors could represent an attractive treatment option for patients who are not candidates for GLP-1 therapeutics due to tolerability or other reasons. The company has been developing a series of potent agonists of the amylin and calcitonin receptors, which could play an important role as both single agents or in combination with GLP-1 or dual GLP-1/GIP agonists.
  
  The company plans to file an Investigational New Drug (IND) application for its lead amylin agonist later this quarter.

About Viking Therapeutics, Inc.
Viking Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on the development of novel first-in-class or best-in-class therapies for the treatment of metabolic and endocrine disorders. Viking's research and development activities leverage its expertise in metabolism to develop innovative therapeutics designed to improve patients' lives. Viking's clinical programs include VK2735, a novel dual agonist of the glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors for the potential treatment of various metabolic disorders. The company is evaluating its subcutaneous formulation of VK2735 in a Phase 3 obesity program that includes two Phase 3 clinical trials (VANQUISH-1 and VANQUISH-2). Data from a Phase 1 and a Phase 2 trial evaluating subcutaneous VK2735 demonstrated an encouraging safety and tolerability profile as well as positive signs of clinical benefit. Concurrently, the company is evaluating an oral formulation of VK2735 in obesity. Viking is also developing VK2809, a novel, orally available, small molecule selective thyroid hormone receptor beta agonist for the treatment of lipid and metabolic disorders. The compound successfully achieved both the primary and secondary endpoints in a Phase 2b study for the treatment of biopsy-confirmed non-alcoholic steatohepatitis (NASH) and fibrosis. In a Phase 2a trial for the treatment of non-alcoholic fatty liver disease (NAFLD) and elevated LDL-C, patients who received VK2809 demonstrated statistically significant reductions in LDL-C and liver fat content compared with patients who received placebo. The company's newest program is evaluating a series of internally developed dual amylin and calcitonin receptor agonists (or DACRAs) for the treatment of obesity and other metabolic disorders. In the rare disease space, Viking is developing VK0214, a novel, orally available, small molecule selective thyroid hormone receptor beta agonist for the potential treatment of X-linked adrenoleukodystrophy (X-ALD). In a Phase 1b clinical trial in patients with the adrenomyeloneuropathy (AMN) form of X-ALD, VK0214 was shown to be safe and well-tolerated, while driving significant reductions in plasma levels of very long-chain fatty acids (VLCFAs) and other lipids, as compared to placebo.
