Spero Therapeutics, Inc. Loss Submission Form

The Gross Law Firm notifies investors that a class action has commenced in the United States District Court for the Eastern District of New York on behalf of shareholders of Spero Therapeutics, Inc. who purchased shares between May 6, 2021 and May 2, 2022.

The filed complaint alleges that defendants made materially false and/or misleading statements and/or failed to disclose that:

(i) the data submitted in support of the New Drug Application (“NDA”) for the Company’s product candidate, Tebipenem HBr, were insufficient to obtain approval from the U.S. Food and Drug Administration (“FDA”); (ii) accordingly, it was unlikely that the FDA would approve the Tebipenem HBr NDA in its current form; (iii) the foregoing would necessitate a significant workforce reduction and restructuring of Spero’s operations; and (iv) as a result, the Company’s public statements were materially false and misleading at all relevant times.

Spero Therapeutics, Inc.
