SAN DIEGO, Nov. 13, 2026 (GLOBE NEWSWIRE) -- Aardvark Therapeutics, Inc. (Aardvark or the Company) (Nasdaq: AARD), a clinical-stage biopharmaceutical company developing novel, small-molecule therapeutics designed to suppress hunger for the treatment of Prader-Willi Syndrome (PWS) and metabolic diseases, today reported financial results for the third quarter ended September 30, 2026, and provided business updates.
“The lifting of the clinical hold and the FDA's agreement that we may conduct an open-label trial at 200 mg twice daily are important steps toward resuming clinical development of ARD-101 in PWS,” said Tien Lee, M.D., Founder and Chief Executive Officer of Aardvark.“We have developed a proposed clinical development plan and look forward to discussing it with the FDA. We remain committed to advancing ARD-101 for patients and families affected by PWS.”
Pipeline Updates
In October 2026, the U.S. Food and Drug Administration (FDA) lifted the clinical hold on the Company's Investigational New Drug (IND) application for ARD-101 for the treatment of hyperphagia in PWS. As required by the FDA, the Company conducted an electrocardiogram (ECG) study in healthy volunteers and an in vitro cardiac sodium channel (NaV1.5) study. No prolongation of the QRS interval or the QT interval was observed at ARD-101 doses of 200 mg or 400 mg twice daily (BID). The FDA has agreed that Aardvark may conduct an open-label trial at 200 mg BID in patients with PWS. In October 2026, Aardvark reported exploratory data from the terminated Phase 3 Hunger Elimination or Reduction Objective (HERO) trial and the open-label extension (OLE) trial. The HERO trial randomized 67 of the planned 90 participants before it was terminated early; as such, all efficacy data are considered exploratory, observational, inconclusive and too limited to support reliable interpretation. Highlights included: Hyperphagia Questionnaire for Clinical Trials (HQ-CT) scores decreased in both treatment groups, with numerically greater reductions for ARD-101 than placebo at Weeks 2, 4, and 8. Due to early termination, evaluable participants declined from 30 (ARD-101) and 31 (placebo) at Week 2 to 11 and 13, respectively, at Week 12, limiting interpretation of the exploratory findings. In the HERO intent-to-treat population with baseline HQ-CT scores of 13 or greater, the mean improvement from baseline in the clinician-rated Clinical Global Impression of Severity (CGI-S) score was numerically greater with ARD-101 than with placebo at every scheduled visit, including Week 12. In the OLE cohort, participants who switched from placebo to ARD-101 had an observed average additional reduction of 6 points in HQ-CT score after four weeks of treatment. Among OLE participants who received either placebo or ARD-101 in the HERO trial, there was an average 11.8-point reduction in HQ-CT score relative to their baseline score at the start of the HERO trial. The OLE trial was open-label and did not include a control group. ARD-101 was generally well tolerated, with most adverse events being mild to moderate. In the HERO trial, treatment-emergent adverse events were reported in 52% of ARD-101 participants and 50% of placebo participants, and treatment-related adverse events were reported in 15% of ARD-101 participants and 21% of placebo participants. One serious cardiac adverse event was observed in the HERO trial at 800 mg BID in a participant who was also taking pitolisant, a CYP2D6 substrate. The FDA concurred that this event was due to a drug-drug interaction with pitolisant. ARD-101 inhibits CYP2D6, the enzyme that metabolizes pitolisant. As with other approved drugs that inhibit CYP2D6, Aardvark believes this risk may be able to be managed through measures such as restricting, or adjusting the dose of, concomitant medications that are CYP2D6 substrates.
Following the lifting of the clinical hold, Aardvark requested a meeting with the FDA, which has been scheduled for the first quarter of 2027, to discuss its proposed clinical development plan for ARD-101 in PWS. The Company intends to provide further details on the development pathway following FDA feedback. The Company expects to resume PWS clinical activities in 2027, subject to alignment with the FDA.
Corporate Update
In October 2026, Aardvark appointed David Zhang, Ph.D., MBA, to its Board of Directors as an independent director. Dr. Zhang brings more than 25 years of experience in clinical strategy, biostatistics and regulatory submissions, including oversight of the pivotal trial design, readout and New Drug Application for CAMZYOS® (mavacamten) at MyoKardia. He currently serves as Chief Strategy Officer of Abivax S.A.
Third Quarter 2026 Financial Highlights
Cash Position: As of September 30, 2026, Aardvark had cash, cash equivalents and short-term investments of $60.3 million, compared to $73.9 million as of June 30, 2026. Based on current operating plans, Aardvark believes that its existing cash, cash equivalents and short-term investments will be sufficient to fund projected operations through 2027. Research & Development (R&D): R&D expenses for the third quarter of 2026 were $15.7 million, compared to $13.7 million for the third quarter of 2025. The $1.9 million increase for the three months ended September 30, 2026 as compared to the three months ended September 30, 2025 resulted primarily from costs associated with the FDA-required cardiac safety study of ARD-101 and higher personnel-related costs, partially offset by lower clinical trial costs following the termination of the HERO and OLE trials. General & Administrative (G&A): G&A expenses were $4.0 million for each of the third quarters of 2026 and 2025. Net Loss: Aardvark reported a net loss of $19.2 million for the third quarter of 2026, compared to $16.3 million for the third quarter of 2025.
