Spero, a clinical-stage biopharmaceutical company, focuses on identifying, developing, and commercializing treatments for multi-drug resistant bacterial infections and rare diseases in the United States.  The Company's product candidates include Tebipenem Pivoxil Hydrobromide (HBr), an oral carbapenem-class antibiotic to treat complicated urinary tract infections, including pyelonephritis for adults.

On October 28, 2021, Spero announced that it had submitted a New Drug Application ("NDA") to the U.S. Food and Drug Administration ("FDA") for Tebipenem HBr for the Treatment of Complicated Urinary Tract Infections including Pyelonephritis (the "Tebipenem HBr NDA").

The complaint alleges that, throughout the Class Period, Defendants made materially false and misleading statements regarding the Company's business, operations, and prospects. Specifically, Defendants made false and/or misleading statements and/or failed to disclose that: (i) the data submitted in support of the Tebipenem HBr NDA were insufficient to obtain FDA approval; (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.

On March 31, 2022, Spero issued a press release announcing the Company's fourth quarter and full year 2021 financial results. In the press release, Spero disclosed that "[t]he U.S. Food and Drug Administration (FDA) has notified Spero that, as part of its ongoing review of Spero's New Drug Application (NDA) for tebipenem HBr, it has identified deficiencies that preclude discussion of labeling and post-marketing requirements/commitments at this time." 

On this news, Spero's stock price fell $1.59 per share, or 18.27%, to close at $7.11 per share on April 1, 2022. 

Then on May 3, 2022, Spero issued a press release announcing "that it will immediately defer current commercialization activities for tebipenem HBr based on feedback from a recent Late Cycle Meeting with the U.S. Food and Drug Administration (FDA) regarding Spero's New Drug Application (NDA) for tebipenem HBr[,]" and that, "[a]lthough the review is still ongoing and the FDA has not yet made any final determination regarding approvability, the discussion suggested that the data package may be insufficient to support approval during this review cycle."  Specifically, the FDA advised the Company, in relevant part, that the FDA's separate analysis of the relevant study population had "reduce[d] the number of evaluable patients in the primary analysis population compared with those resulting from the trial's pre-specified micro-ITT population as outlined in the statistical analysis plan and [a]s a result, the FDA considers that the pre-specified non-inferiority margin of -12.5% was not met." Further, the press release advised that, "[i]n connection with this development, Spero announced that it is undertaking a reduction in its workforce by approximately 75% and a restructuring of its operations to reduce operating costs and reallocate resources."

On this news, Spero's stock price fell $3.24 per share, or 63.65%, to close at $1.85 per share on May 3, 2022.
