Company Announcements

SAN FRANCISCO , May 28, 2026 /PRNewswire/ -- On March 2, 2026, investors in Aardvark Therapeutics (NASDAQ: AARD) saw the price of their shares crater $7.02 (-56%) after the company announced that it stopped its Phase 3 Hunger Elimination of Reduction Objective ("HERO") trial evaluating the efficacy and safety of ARD-101 as a treatment for hyperphagia (insatiable hunger) in patients with Prader-Willi Syndrome ("PWS").

Aardvark Therapeutics (AARD) Investigation:

The investigation is focused on the propriety of Aardvark's disclosures about ARD-101 safety and efficacy data, along with disclosures regarding communications with the FDA.

In the past, Aardvark has emphasized that ARD-101 represented a "first-in-class" drug and that, "through alignment with the FDA," it started HERO patients 13 years and older, moved to dosing patients 10 years and older, and intended to dose patients as young as 4 years old.

The company has also assured investors that ARD-101 has "a very tolerable safety profile."

Investors' expectations were dashed on March 2, 2026. That day, Aardvark abruptly announced that it was pausing the HERO trial. The company said its decision was based on a serious safety risk – namely, "reversible cardiac observations[.]" Aardvark also said that it no longer anticipates announcing topline data from the HERO trial during the third quarter of 2026.

The market swiftly reacted, sending the price of Aardvark shares down by over half and, with the emergence of cardiac safety signals, reportedly prompting several analysts to sharply reduce or suspend their price targets.

"We're focused on whether Aardvark may have misled investors about ARD-101's development, its safety and/or efficacy, and the company's communications with the FDA," said Reed Kathrein, the Hagens Berman partner leading the firm's investigation.
