SAN DIEGO, July 23, 2025 /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 second quarter and six months ended June 30, 2025, and provided an update on its clinical pipeline and other corporate developments.

Highlights from the Quarter Ended June 30, 2025, and Other Recent Events:

"The Viking team achieved significant execution and clinical milestones during the first half of 2025," stated Brian Lian, Ph.D., chief executive officer of Viking.  "With respect to our VK2735 program for obesity, we recently announced the initiation of the VANQUISH Phase 3 registration program, consisting of two studies: one in patients with obesity and one in patients with obesity and type 2 diabetes.  Also during the first half of the year, we announced both the initiation and completion of enrollment in the Phase 2 VENTURE-Oral Dosing study of our oral tablet formulation of VK2735.  We believe the study's rapid enrollment speaks to continued strong demand for new and differentiated weight loss therapies.  We remain on track to announce top-line data from the VENTURE-Oral study in the second half of the year.  With respect to our amylin agonist program, we continue to make progress toward an IND filing, which we expect to submit later this year.  Importantly, we completed the second quarter with a strong balance sheet providing the runway to support the advancement of VK2735 through Phase 3 clinical trials, in addition to supporting further progress with other key development programs."

Pipeline and Recent Corporate Highlights

• Phase 3 VANQUISH Registration Trials for Subcutaneous VK2735 Underway. 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.
  
  In 2024, Viking announced positive top-line results from its Phase 2 VENTURE study of subcutaneous VK2735 in obesity.  The VENTURE trial successfully achieved its primary and secondary endpoints, with subjects receiving VK2735 demonstrating statistically significant reductions in body weight compared with placebo.  After 13 weekly doses, subjects receiving VK2735 demonstrated statistically significant reductions in mean body weight from baseline, ranging up to 14.7%.  VK2735 also demonstrated encouraging safety and tolerability in the VENTURE study, with the majority of observed adverse events (AEs) being reported as mild or moderate.  Treatment and study discontinuation rates among VK2735 cohorts were well-balanced compared with placebo.  The results of the VENTURE study were presented in November 2024 at ObesityWeek^â, the annual meeting of The Obesity Society.
  
  Based on these promising Phase 2 results, along with feedback from a Type C meeting and subsequent End of Phase 2 meeting with the U.S. Food and Drug Administration (FDA), the company advanced VK2735 into Phase 3 development for obesity.  In the second quarter, the company announced the initiation of the VANQUISH Phase 3 clinical program, which includes two studies evaluating VK2735: one in adults with obesity and one in adults with obesity or who are overweight and have type 2 diabetes.  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 will target enrollment of approximately 4,500 adults with obesity (BMI ≥30 kg/m²) or who are overweight (BMI ≥27 kg/m²) with at least one weight-related co-morbid condition.  The VANQUISH-2 study will target enrollment of approximately 1,100 adults with type 2 diabetes with obesity or who are overweight.  Participants in both trials will be randomized to one of four weekly treatment arms of 7.5 mg, 12.5 mg, 17.5 mg, or placebo.
  
  The primary endpoint of the trials is the percent change in body weight from baseline for participants receiving VK2735 as compared to placebo after 78 weeks of treatment.  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 include an open-label extension allowing participants the opportunity to continue receiving treatment following completion of the primary dosing period.
  
  Viking will provide further updates on the VANQUISH program as these studies progress.
  
  
• Phase 2 VENTURE-Oral Dosing Trial Enrollment Completed; Top-Line Results Expected 2H25.  Concurrent with the development of a subcutaneous formulation, Viking is also developing an oral tablet formulation of VK2735, which the company believes could represent an attractive treatment option for people who may prefer to initiate treatment with an oral therapy, or for those seeking to maintain the weight loss they have already achieved.  A differentiating feature of the tablet formulation of VK2735 is that it offers the potential to transition subjects from the subcutaneous formulation to an oral formulation of the same molecule.  Viking believes this may reduce the risk of unexpected safety or tolerability challenges and could be an appealing option for both patients and clinicians.
  
  In 2024, Viking reported the results from a Phase 1 multiple ascending dose trial evaluating oral VK2735 doses ranging from 2.5 mg to 100 mg.  This trial successfully achieved its primary and secondary objectives, with the results showing that cohorts receiving VK2735 demonstrated dose-dependent reductions in mean body weight from baseline, ranging up to 8.2% after 28 days.  Persistent weight loss effects ranging up to 8.3% from baseline were observed at follow-up visits through Day 57, four weeks after the last dose of VK2735 was administered.  Oral VK2735 also demonstrated encouraging safety and tolerability through 28 days of once-daily dosing at doses up to and including 100 mg.  The majority of observed treatment emergent adverse events were mild or moderate, with the majority reported as mild.  These results were presented last November at ObesityWeek 2024.
  
  In January 2025, the company announced the initiation of the Phase 2 VENTURE-Oral Dosing trial in subjects with obesity.  This trial is a randomized, double-blind, placebo-controlled multicenter study designed to evaluate the safety, tolerability, pharmacokinetics and weight loss efficacy of VK2735 dosed as an oral tablet once daily for 13 weeks.  The target population consists of adults with obesity (BMI ≥30 kg/m²) or who are overweight (BMI ≥27 kg/m²) with at least one weight-related co-morbid condition.  Enrolled subjects are evenly randomized to one of six dosing arms or placebo.  The primary endpoint of the study is the percent change in body weight from baseline after 13 weeks of treatment.  Secondary and exploratory endpoints will evaluate a range of additional safety and efficacy measures.
  
  In March, Viking announced completion of enrollment for this trial, enrolling approximately 280 patients.  The company expects to report the results from this study in the second half of 2025.
  
  
• Continued Progress with Dual Amylin and Calcitonin Receptor Agonist (DACRA) Program; IND Expected 4Q25.  The amylin and calcitonin receptors have been shown to play an important role in food intake and metabolic control, making them attractive therapeutic targets for obesity.
  
  In 2024 Viking announced a new, internally developed DACRA program for the treatment of obesity.  In vivo data from this program were presented at the 2024 American Diabetes Association's (ADA's) Annual Scientific Sessions.  The company's ADA presentation highlighted the effects of treatment on body weight, food intake and metabolic profile in both healthy rats and in diet-induced obese mice.  The results demonstrated that Viking's DACRAs reduced food intake in rodents following a single subcutaneous dose.  
  
  Viking plans to file an investigational new drug (IND) application for this program in the fourth quarter of 2025.

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 a Phase 2 trial 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 recently completed 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 demonstrated a promising safety profile and was well-tolerated, while driving significant reductions in plasma levels of very long-chain fatty acids (VLCFAs) and other lipids, as compared to placebo.
