Spero Therapeutics Transitions Leadership Amid Regulatory Scrutiny

Spero Therapeutics Transitions Leadership Amid Regulatory Scrutiny

CAMBRIDGE, Mass. - Spero Therapeutics, Inc. (NASDAQ: SPRO), a biopharmaceutical company focused on developing therapies for rare diseases and combatting drug-resistant infections, has announced new leadership as a response to a recent Securities and Exchange Commission (SEC) Wells Notice. This notice pertains to potential issues related to public disclosures made in the spring of 2022. Esther Rajavelu has taken charge as Interim President and CEO, while Frank Thomas assumes the role of Chairman of the Board.

The decision to implement interim leadership stems from the SEC's preliminary recommendation for enforcement action, although it should be noted that this is not a formal charge nor a conclusion of wrongdoing. The Board has declared that the company and its executives acted with integrity and are fully cooperating with the SEC during this inquiry. Despite facing significant stock pressure, which has seen a 9% dip over the past week and a notable 33% drop within the past year, the company continues to maintain a positive outlook.

In addition to management changes, Spero Therapeutics reported positive advancements in its clinical trial for Tebipenem HBr, an investigational oral antibiotic aimed at treating complicated urinary tract infections. The Phase 3 PIVOT-PO trial has now exceeded 60% enrollment and is expected to reach full enrollment by mid-2025. The company has enough cash reserves to support its operations until mid-2026, showcasing a resilient financial strategy.

Financial Condition and Research Progress

Despite the turmoil surrounding its leadership, Spero Therapeutics has displayed a strong financial stance. Recent analysis indicates profitability over the previous twelve months with a gross profit margin of 52%. However, market expectations suggest a potential decline in sales this year, adding layers of complexity to the company's financial outlook.

Esther Rajavelu's leadership journey with Spero began as Chief Financial and Business Officer in November 2023, and Frank Thomas has been an integral board member since July 2017. These appointments come at a time when the company is doubling down on its clinical programs, particularly focusing on Tebipenem HBr's development amidst recent setbacks in other projects.

Pilley into Pipeline Developments

Spero Therapeutics has also shared updates on additional pipeline initiatives. Notably, the Phase 2a trial for SPR720 aimed at Non-Tuberculous Mycobacterial-Pulmonary Disease did not achieve its primary endpoint, while SPR206, focused on treating bacterial pneumonia, is gearing up for a Phase 2 trial, pending future funding opportunities.

Market Reactions and Future Outlook

Recent reports indicate that Spero Therapeutics recorded Q2 2024 revenues of $10.2 million, along with a net loss of $17.9 million. In light of discontinuing a particular Phase 2 program, the company has made the difficult decision to reduce its workforce by approximately 39%. Nonetheless, positive strides continue in the Phase 3 trial for Tebipenem HBr, in collaboration with GlaxoSmithKline (NYSE: GSK), signaling continued commitment to its drug development pipeline.

H.C. Wainwright recently reaffirmed a Buy rating on Spero Therapeutics, highlighting the critical ongoing enrollment in the PIVOT-PO trial. Expectation is building around the eventual completion of this trial by mid-2025, with results anticipated in early 2026. Conversely, there are cautionary sentiments from TD Cowen, who downgraded Spero from Buy to Hold, reflecting concerns over the uncertain timelines related to future milestones.

Development Program Adjustments

In a strategic pivot, Spero Therapeutics has ceased further development of the SPR720 program, following an interim analysis indicating that the drug did not meet its expected benchmarks in trial outcomes. However, the focus remains sharp on advancing other promising therapies, such as the upcoming Phase 2 trial for SPR206, dependent upon securing necessary funding.

The company maintains robust financial health with a cash reserve of $76.3 million, anticipated to sufficiently cover operational costs into mid-2026. These efforts and strategic decisions form the foundation of Spero Therapeutics' approach during this transformative period.
