What is the Lawsuit About?

The complaint alleges that Aardvark Therapeutics, a clinical-stage biopharmaceutical company focused on developing small-molecule therapies targeting bitter taste receptors (TAS2Rs) such as ARD-101 for the treatment of hyperphagia in Prader-Willi Syndrome (PWS), made materially false and misleading statements and/or failed to disclose critical information.

Specifically, the action points out that the offering documents and defendants failed to disclose:

1. That ARD-101 was significantly less safe than defendants had led investors to believe;
2. That unexpected, reversible cardiac observations (such as QRS prolongation) occurred during trials at above-target doses; and
3. Consequently, Aardvark's clinical, regulatory, and commercial prospects—including the Phase 3 Hunger Elimination or Reduction Objective (HERO) trial and open-label extension (OLE)—were materially overstated.

The Truth Emerges: Voluntarily Pause and FDA Clinical Hold

• February 27, 2026: Aardvark announced it was voluntarily pausing its Phase 3 HERO trial due to "reversible cardiac observations at above target therapeutic doses found during routine safety monitoring in a healthy volunteer study." Following this news, Aardvark's stock price plummeted over 56%.
• May 14, 2026: Aardvark announced that the U.S. Food and Drug Administration (FDA) placed a full clinical hold on its investigational new drug application (IND) for ARD-101, halting all ongoing studies under the IND, including the Phase 3 HERO trial and OLE trial. Aardvark's stock price fell another 32.1%.

Hagens Berman's Investigation

"We're investigating the suit's allegations, including that Aardvark allegedly misled investors about ARD-101's development, its safety and efficacy," said Reed Kathrein, the Hagens Berman partner leading the firm's investigation of the claims in the pending suit.
