A securities class action lawsuit has been filed against Aardvark Therapeutics, Inc. in the Southern District of California. The case concerns Aardvark's February 13, 2025 IPO and later purchases through May 14, 2026.
The complaint alleges defendants made materially false and misleading statements about ARD-101's safety profile. Investors were told the drug was well-tolerated and largely gut-restricted, but later disclosures described cardiac observations.
Aardvark shares fell sharply after the company paused the Phase 3 HERO trial. The stock fell again after the FDA placed a full clinical hold on ARD-101.
Aardvark Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on developing small-molecule therapies designed to inhibit hunger and treat metabolic diseases. At the time of its IPO, its lead product candidate was ARD-101, an oral gut-restricted small-molecule agonist being evaluated in the Phase 3 HERO trial for hyperphagia associated with Prader-Willi Syndrome.
February 13, 2025 – May 14, 2026
Investors who purchased Aardvark Therapeutics, Inc. securities during the class period might be eligible to join the Aardvark Therapeutics, Inc. securities class action lawsuit.
The complaint brings Securities Act and Exchange Act claims tied to Aardvark's IPO and subsequent public statements during the trading period. According to the lawsuit, Aardvark sold 5,888,000 shares of common stock in its February 13, 2025 IPO at $16.00 per share, raising proceeds of $87,613,440 after underwriting discounts and commissions. The Registration Statement was filed on Form S-1 on January 23, 2025, declared effective on February 12, 2025, and followed by a Form 424B4 Prospectus on February 13, 2025.
The Offering Documents allegedly represented that ARD-101 had limited systemic absorption, was approximately 99% restricted to the gut, had minimal systemic exposure, and was well-tolerated in clinical trials to date. They also stated that ARD-101 resulted in no serious adverse events, no renal or hepatic safety limitations, and no evidence of immunosuppression. The complaint alleges these statements omitted material facts because ARD-101 was less safe than defendants led investors to believe, which overstated the drug's clinical, regulatory, and commercial prospects.
After the IPO, Aardvark and its executives allegedly continued to reinforce the same safety narrative. The company's March 31, 2025 Form 10-K stated that limited systemic absorption reduced the potential for systemic toxicity. In May 2025, Defendant Tien-Li Lee said Aardvark had dosed more than 70 patients with ARD-101 and had not seen anything more than a grade 2 adverse event, while Defendant Bryan Jones described ARD-101 as having a "Very, very clean" safety profile and said the chance of side effects was "very, very low" because the drug did not expose other tissues.
The complaint further alleges that defendants repeated these claims at investor conferences and in SEC filings through late 2025. On September 8, 2025, Defendant Lee stated that the company's target 800 mg twice-daily dose was "far below the toxic limit" of ARD-101 and that lack of systemic exposure diminished concern for "cardiac toxins." Plaintiffs allege defendants knew or recklessly disregarded that ARD-101 was less safe than they had led investors to believe and that its clinical, regulatory, and commercial prospects were overstated.
The alleged truth began to emerge when Aardvark issued a February 27, 2026 press release announcing that it was voluntarily pausing enrollment and dosing in the Phase 3 HERO trial. The company attributed the pause to "reversible cardiac observations at above target therapeutic doses" found during routine safety monitoring in a healthy volunteer study. Aardvark also said it no longer anticipated announcing topline data from the HERO trial in the third quarter of 2026.
Analysts responded by reducing price targets and citing increased uncertainty around ARD-101. Morgan Stanley Research downgraded Aardvark from Overweight to Equal-weight and cut its price target from $29 to $7, citing uncertainty around the path forward for ARD-101. BTIG reduced its target from $26 to $9, citing increased risk around the HERO trial, while Bank of America Securities reduced its target from $25 to $21.
The truth continued to emerge on May 14, 2026, when Aardvark announced that the U.S. Food and Drug Administration had placed a full clinical hold on its investigational new drug application for ARD-101. The clinical hold applied to all ongoing studies under the IND, including the Phase 3 HERO trial and the Phase 3 open-label extension trial. This disclosure allegedly contradicted earlier statements suggesting that Aardvark had a clear path forward and that ARD-101's safety profile remained encouraging.
Aardvark's stock fell $7.02 per share, or 56.2%, to close at $5.47 per share on March 2, 2026, after the company announced the voluntary pause of the HERO trial. That closing price was approximately 65.8% below the $16.00 IPO offering price, reflecting the market's reaction to the first major safety-related disclosure.
After the FDA full clinical hold was announced, AARD fell another $2.16 per share, or 32.1%, to close at $4.57 per share on May 15, 2026. That closing price was approximately 71.4% below the $16.00 offering price. Analysts again reduced or withdrew price targets, with Morgan Stanley cutting its target from $7 to $3, Bank of America Global Research cutting its target from $18 to $4, and BTIG downgrading the stock to Neutral and rescinding its $9 target.
● Lead Plaintiff Deadline: October 13, 2026
● After the lead plaintiff deadline, the Court will consider any lead plaintiff motions.
● Defendants may file a motion to dismiss.
● If the case proceeds, the Court may later consider class certification.

The Aardvark Therapeutics shareholder lawsuit alleges that the company and certain executives and directors misled investors about the safety and prospects of ARD-101, Aardvark's lead product candidate. According to the complaint, Aardvark repeatedly described ARD-101 as well-tolerated, gut-restricted, and unlikely to create systemic safety concerns. Plaintiffs allege those statements were materially false and misleading because ARD-101 was less safe than represented, which overstated its clinical, regulatory, and commercial prospects.
The complaint defines the class as persons and entities, other than defendants, that purchased or otherwise acquired Aardvark common stock pursuant and/or traceable to the Offering Documents issued in connection with the February 13, 2025 IPO, and/or Aardvark securities between February 13, 2025 and May 14, 2026, inclusive. The complaint excludes defendants, Aardvark's officers and directors at relevant times, their immediate families, legal representatives, heirs, successors, assigns, and entities in which defendants have or had a controlling interest.
Aardvark announced on February 27, 2026 that it was voluntarily pausing enrollment and dosing in the Phase 3 HERO trial for ARD-101. The company attributed the pause to reversible cardiac observations at above target therapeutic doses found during routine safety monitoring in a healthy volunteer study. On this news, AARD fell $7.02 per share, or 56.2%, to close at $5.47 per share on March 2, 2026, according to the complaint.
According to the complaint, Aardvark announced on May 14, 2026 that the FDA had placed a full clinical hold on its investigational new drug application for ARD-101. The hold applied to all ongoing studies under the IND, including the Phase 3 HERO trial and the Phase 3 open-label extension trial. Plaintiffs allege this disclosure further revealed the safety and regulatory risks that had been understated in earlier statements about ARD-101.
The complaint challenges statements in Aardvark's IPO Offering Documents, SEC filings, press releases, investor conferences, and an investor webinar. These statements allegedly described ARD-101 as well-tolerated, having limited systemic absorption, being approximately 99% restricted to the gut, and presenting a very low chance of side effects. Plaintiffs also cite statements that the company had aligned with the FDA on the HERO trial design and believed the trial could support an NDA filing.
The defendants are Aardvark Therapeutics, Inc. and individual defendants Tien-Li Lee, M.D.; Nelson Sun; Bryan Jones, Ph.D.; Jeffrey Chi, Ph.D., CFA; Roy D. Baynes, M.D., Ph.D.; Susan E. Graf, RPh, MBA; and Victor Tong, Jr. The complaint identifies Lee as Chief Executive Officer and Director, Sun as Chief Financial Officer and later Chief Operating Officer, Jones as Chief Operating Officer until February 9, 2026, and the remaining individual defendants as directors who signed or authorized the Registration Statement.
The complaint asserts claims under Sections 11 and 15 of the Securities Act and Sections 10(b) and 20(a) of the Exchange Act, along with Rule 10b-5. The Securities Act claims focus on alleged misstatements and omissions in the IPO Offering Documents. The Exchange Act claims focus on allegedly materially false and misleading statements during the class period, including statements about ARD-101's safety profile and the company's regulatory outlook.
The lead plaintiff deadline is October 13, 2026. A lead plaintiff is the investor or investor group that seeks appointment by the Court to represent the proposed class. Investors do not need to seek lead plaintiff status to remain potential class members. According to the complaint, the case is brought on behalf of investors who purchased IPO-traceable Aardvark common stock and/or Aardvark securities during the February 13, 2025 through May 14, 2026 class period.
The AARD lawsuit alleges Aardvark misled investors about ARD-101's safety and prospects. Plaintiffs claim the company overstated ARD-101's safety and prospects, including the safety implications of its gut-restricted profile and tolerability, before cardiac observations and an FDA clinical hold were disclosed.
The class period runs from February 13, 2025 through May 14, 2026, inclusive. The complaint also covers investors who purchased Aardvark common stock pursuant and/or traceable to the February 13, 2025 IPO Offering Documents.
AARD fell $7.02 per share, or 56.2%, to $5.47 on March 2, 2026 after the HERO trial pause. It later fell $2.16 per share, or 32.1%, to $4.57 on May 15, 2026 after the FDA clinical hold.
Aardvark disclosed reversible cardiac observations at above target therapeutic doses in a healthy volunteer study. Later, the company announced that the FDA had placed a full clinical hold on the ARD-101 IND, covering the HERO trial and open-label extension.
No action is required to remain a potential class member. The lead plaintiff deadline is October 13, 2026, and investors may decide whether to seek lead plaintiff appointment based on their own circumstances.
