Attorney Advertising

Are you a Zenas BioPharma, Inc. (NASDAQ: ZBIO) investor who bought shares in the company’s September 2024 IPO? If so, you may be eligible to join a class action lawsuit now pending in the U.S. District Court for Massachusetts.

CASE BACKGROUND: Zenas BioPharma is a clinical-stage biopharmaceutical company developing immunology-based therapies. A complaint filed on April 16, 2025, in the U.S. District Court for the District of Massachusetts alleges that the company, certain executives and directors, and the underwriters of its IPO violated federal securities laws. The complaint alleges that the Registration Statement for the IPO contained materially false and misleading statements and omitted critical information, particularly overstating the duration Zenas could fund operations with IPO proceeds and existing cash.

Shortly after the IPO, Zenas BioPharma revealed in its third quarter 2024 financial results that it could fund operations for 12 months—not 24 months as previously stated. Following this disclosure, Zenas shares fell significantly, closing at $8.72 per share on April 15, 2025, nearly 49% below the IPO price of $17.00 per share.

NEXT STEPS: If you purchased shares of Zenas BioPharma pursuant and/or traceable to the September 2024 IPO and suffered a significant loss, and are interested in serving as lead plaintiff, you must move the court no later than June 16, 2025, to request appointment as lead plaintiff. You are not required to file a lead plaintiff motion to participate in any potential recovery as a class member.
