SAN DIEGO, CA, November 13, 2025 (GLOBE NEWSWIRE) -- Aardvark Therapeutics, Inc. (Aardvark) (Nasdaq: AARD), a clinical-stage biopharmaceutical company focused on developing novel, small-molecule therapeutics to activate innate homeostatic pathways for the treatment of metabolic diseases, today reported financial results for the third quarter ended September 30, 2025, and provided pipeline and business updates.

“During ObesityWeek, we highlighted new preclinical data demonstrating the potential of ARD-201 in enhanced glucose control, along with preservation of lean mass, underscoring its opportunity in addressing key challenges in today’s obesity treatment landscape. The data were met with encouraging feedback from Key Opinion Leaders who attended the meeting,” said Tien Lee, M.D., Founder and Chief Executive Officer of Aardvark. “We also presented clinical data on ARD-101 and preclinical data on ARD-201 demonstrating the potential of oral ARD-201 to attenuate weight gain, promote weight loss and help maintain weight after GLP-1RA discontinuation. We’re looking forward to advancing ARD-201 into two Phase 2 trials, POWER and STRENGTH, to further evaluate its potential for individuals living with metabolic obesity.”

Clinical Program Updates

ARD-101 for PWS

In October 2025, Aardvark reached alignment with the FDA on a protocol amendment to change the minimum age of eligibility to participate in the Phase 3 HERO trial of ARD-101 for the treatment of hyperphagia associated with PWS trial from 13 to 10 years of age. This change broadens the eligible population for the trial and expands the potential target market within the PWS market. In addition, during the third quarter of 2025, Aardvark commenced enrollment for the HERO Open Label Extension (OLE) trial and initiated its first clinical trial sites in Australia with a minimum age of eligibility to participate at 10 years of age. The OLE trial is available to patients completing the HERO clinical trial.

ARD-201 for Obesity

At ObesityWeek 2025, Aardvark presented preclinical data on ARD-201 and clinical data on ARD-101 supporting the continued development of ARD-201 to attenuate weight gain, promote weight loss, and help maintain weight after the discontinuation of glucagon-like peptide-1 receptor agonist (GLP-1RA) therapies. In addition, ARD-201 improved glucose tolerance and lean body mass composition. Highlights from the data presented included:

•

Preclinical – ARD-201 (Validated Diet-Induced Obesity (DIO) Mouse Model):

Transition from high-dose tirzepatide to ARD-201 preserved lean mass

Transition to ARD-201 achieved glucose control comparable to staying on high-dose tirzepatide, while a combination of ARD-201 with low-dose tirzepatide further enhanced glucose clearance

Previously reported preclinical data demonstrated ARD-201 reduced body weight by ~19% after 30 days, which was comparable to high-dose tirzepatide

Previously reported preclinical data demonstrated ARD-201 achieved ~30% weight loss when combined low-dose tirzepatide

•

Clinical – ARD-101 (Randomized, 28-Day, Placebo-Controlled, Phase 2A Study in Adults with Obesity):

ARD-101 showed signals of weight control, reduced hunger, and improved metabolic parameters, particularly among participants with elevated baseline values

ARD-101 was well tolerated, with no serious adverse events or treatment discontinuations, reflecting a distinct profile from the effects associated with current anti-obesity therapies

Anticipated Milestones

•

Topline data from the Phase 3 HERO trial evaluating ARD-101 for the treatment of hyperphagia associated with PWS is expected in the third quarter of 2026

•

Preliminary or interim data from the Phase 2 POWER trial is anticipated to be available in 2H 2026.

Select Third Quarter 2025 Financial Highlights

•

Cash Position: As of September 30, 2025, Aardvark had cash, cash equivalents, and short-term investments of $126.4 million. Based on current operating plans, Aardvark believes that its existing cash, cash equivalents, and short-term investments will be sufficient to fund projected operations into 2027.

•

R&D Expenses: Research and development expenses were $13.7 million and $4.1 million for the quarter ended September 30, 2025, and 2024, respectively. The $9.7 million increase for the quarter ended September 30, 2025, resulted from increased development costs primarily related to ARD-101 and an increase in personnel-related expenses.

•

G&A Expenses: General and administrative expenses were $4.0 million and $1.0 million for the quarter ended September 30, 2025, and 2024, respectively. The $2.9 million increase for the quarter ended September 30, 2025, primarily resulted from increases in personnel-related costs, facilities and other costs, and professional fees, which were partially related to commencing operations as a public company in February 2025.

•

Net loss: Net loss for the quarter ending September 20, 2025, was $16.3 million compared to $4.2 million quarter ending September 20, 2024, primarily due to increased research and development and general and administrative expenses.

About Aardvark Therapeutics, Inc.

Aardvark is a clinical-stage biopharmaceutical company developing novel, small-molecule therapeutics designed to suppress hunger for the treatment of Prader-Willi Syndrome and metabolic diseases. Recognizing hunger (the discomfort from not having eaten recently) is a distinct neural signaling pathway separate from appetite (the reward-seeking, desirability of food). Our programs explore therapeutic applications in hunger-associated indications and potential complementary uses with anti-appetite therapies. Our lead compound, oral ARD-101, is in Phase 3 clinical development for the treatment of hyperphagia associated with PWS, a rare disease characterized by insatiable hunger. Aardvark is also developing ARD-201, a planned fixed-dose combination of ARD-101 with a DPP-4 inhibitor and conducting two separate trials with a goal of addressing some of the limitations of currently marketed GLP-1 therapies for the treatment of obesity and obesity-related conditions.
