Insights
The announcement by Spero Therapeutics regarding their financial results and pipeline progress presents a multifaceted picture for stakeholders. The reported net income of $51.2 million for Q4 2023 and an overall net income of $22.8 million for the year is a significant turnaround from the net loss of $(46.4) million in the previous year. This improvement is primarily attributed to the collaboration revenue from partnerships with GSK and Pfizer, underscoring the value of strategic alliances in the biopharmaceutical industry. The milestone payments from GSK, including the recent $23.8 million tranche, enhance the company's cash position, extending the cash runway into late 2025, which is crucial for sustaining operations and funding ongoing clinical trials.
However, the increase in research and development expenses, albeit offset by personnel cost savings, indicates an uptick in clinical activity which investors should monitor as it could impact future financials. The anticipated data from the SPR720 Phase 2a trial and the progress of the PIVOT-PO Phase 3 trial for tebipenem HBr are pivotal events that could influence the company's valuation and stock performance. Positive outcomes could lead to potential FDA approval and commercialization, whereas any setbacks may have adverse effects on investor confidence and the company's financial health.
The therapeutic pipeline updates provided by Spero Therapeutics have significant implications for the treatment of rare diseases and multi-drug resistant infections. SPR720, being an oral treatment for NTM-PD, represents a novel approach in a space with limited options. The upcoming top-line data from the Phase 2a trial will be critical in determining its efficacy and safety, which, if positive, could lead to a new standard of care and provide a substantial market opportunity for Spero.
Similarly, tebipenem HBr has the potential to be a game-changer for patients with cUTI by providing an oral treatment alternative to intravenous therapies, potentially reducing hospital stays and healthcare costs. The Phase 3 PIVOT-PO trial, backed by an FDA Special Protocol Assessment, indicates a clear regulatory path forward, which could expedite the approval process upon successful trial outcomes. The unique value proposition of tebipenem HBr, as the first oral broad-spectrum carbapenem in the United States, could significantly impact treatment protocols and market dynamics upon approval.
From an infectious disease perspective, the development of SPR206 is particularly noteworthy due to its activity against MDR Gram-negative pathogens, which are a growing public health concern due to limited treatment options. The advancement into a Phase 2 trial for hospital-acquired or ventilator-associated bacterial pneumonia could address a critical need in hospital settings. The published preclinical and Phase 1 study results provide a scientific basis for its potential efficacy and safety profile. The support from government agencies like the Department of Defense and the National Institute of Allergy and Infectious Diseases underscores the importance of SPR206's target indications and the need for innovative treatments in combating antibiotic resistance.
- On track for topline data from SPR720 Phase 2a proof-of-concept trial in treatment-naive and treatment-experienced non-refractory NTM-PD patients, expected in 2H 2024
- Initiated enrollment in PIVOT-PO, a pivotal Phase 3 clinical trial of oral Tebipenem HBr in cUTI
- Submitted IND for SPR206 and received FDA clearance to proceed with Phase 2 clinical trial
- Reiterate expected cash runway into late 2025
- Conference call and webcast at 4:30pm ET today
CAMBRIDGE, Mass., March 13, 2024 (GLOBE NEWSWIRE) -- Spero Therapeutics, Inc. (Nasdaq: SPRO), a multi-asset clinical-stage biopharmaceutical company, focused on identifying and developing novel treatments for rare diseases and multi-drug resistant (MDR) bacterial infections, today announced financial results for the fourth quarter and full year ended December 31, 2023, and provided a business update.
“2023 was a productive year for Spero and we have been focused on execution across our programs,” said Sath Shukla, President, and Chief Executive Officer of Spero. “We are well poised to unveil top-line data for SPR720 Phase 2a, which is expected in 2H 2024, and our excitement is fueled by the hope it may bring for the rare disease community grappling with nontuberculous mycobacterial pulmonary disease (NTM-PD). On tebipenem HBr, engaging with the FDA and in collaboration with our partner, GSK, we are actively enrolling patients globally in our Phase 3 PIVOT-PO clinical trial. Positioned as the first oral broad-spectrum carbapenem in the United States for cUTI, we believe this product has the potential to change the treatment paradigm for these patients and underscores Spero’s commitment to innovation. We reiterate our expected cash runway into late 2025 based on our year-end cash balance, along with tebipenem HBr development milestone payments from GSK and our disciplined capital allocation.”
Pipeline Update
SPR720
SPR720 is an investigational novel, oral, first-line treatment for NTM-PD.
- Top-line data from the Phase 2a proof-of-concept clinical trial in treatment-naive and treatment-experienced non-refractory NTM-PD patients is expected in 2H 2024. The trial is expected to enroll treatment-naïve or treatment-experienced participants with non-refractory NTM-PD due to Mycobacterium avium complex. The primary endpoint evaluates changes in bacterial load in sputum samples from baseline to the end of the 56-day treatment period. Key secondary endpoints include assessments of clinical response, quality of life, pharmacokinetics, and safety and tolerability. For more information on the trial, see ClinicalTrials.gov identifier NCT05496374.
- A paper Efficacy of SPR720 in murine models of non-tuberculous mycobacterial pulmonary infection (Nicole Cotroneo et al) was published in Journal of Antimicrobial Chemotherapy in February 2024.
- A paper Nontuberculous mycobacterial pulmonary disease and the potential role of SPR720 (Kevin Winthrop et al) was published in Expert Review of Anti-infective Therapy in October 2023.
Tebipenem HBr
Tebipenem HBr is an investigational oral carbapenem antibiotic being developed for the treatment of complicated urinary tract infection (cUTI) including acute pyelonephritis (AP) to help patients avoid hospitalizations or reduce duration of in-patient therapy.
- Spero commenced enrollment in PIVOT-PO, a global, randomized, double-blind, Phase 3 clinical trial of tebipenem HBr in patients with cUTI, including AP in December 2023. The trial compares oral tebipenem HBr with intravenous imipenem cilastatin, in hospitalized adult patients with cUTI/AP. The primary endpoint is the number of patients with overall response (a combination of clinical cure and favorable microbiological response) at the Test-of-Cure (TOC) visit. The trial is expected to enroll approximately 2,648 patients, with enrollment completion anticipated in 2H 2025. For more information on PIVOT-PO, refer to ClinicalTrials.gov ID NCT06059846.
- In July 2023, Spero received written agreement from the U.S. Food and Drug Administration (FDA), under a Special Protocol Assessment (SPA), on the design and size of PIVOT-PO. The FDA has indicated that positive and persuasive results from PIVOT-PO, supported with confirmatory evidence of efficacy, could be sufficient to support approval of tebipenem HBr as a treatment for cUTI, including pyelonephritis, for a limited use indication.
- Under the terms of its license agreement with GSK, in December 2023, upon dosing the first patient, Spero earned
$95 million in development milestones payable in four equal installments over two years. Spero also received a$30 million development milestone payment following the SPA. Further details on the agreement with GSK can be found here.
SPR206
SPR206 is an innovative, investigational IV-administered direct-acting next generation polymyxin that has shown antibiotic activity against MDR Gram-negative pathogens, including carbapenem-resistant Enterobacteriaceae, Acinetobacter baumannii and Pseudomonas aeruginosa in preclinical studies.
- An Investigational New Drug (IND) application has been cleared by the FDA to advance SPR206, to treat MDR Gram-negative bacterial infections, into a Phase 2 clinical trial in participants with hospital-acquired or ventilator-associated bacterial pneumonia.
- The results from the Phase 1 bronchoalveolar lavage (BAL) study of SPR206 were published in a paper Pharmacokinetics of SPR206 in Plasma, Pulmonary Epithelial Lining Fluid, and Alveolar Macrophages following Intravenous Administration to Healthy Adult Subjects (Keith Rodvold et al) in Antimicrobials and Chemotherapy in July 2023.
- A paper Safety and pharmacokinetics of SPR206 in subjects with varying degrees of renal impairment (Jon B. Bruss et al) was published in Antimicrobials and Chemotherapy in October 2023.

Net income for the fourth quarter and net loss for the year ended December 31, 2022, was$26.8 million and$(46.4) million , or$0.55 and$(1.23) per share of common stock, respectively. - Total revenue for the fourth quarter of 2023 was
$73.5 million , compared with total revenue of$47.4 million for the fourth quarter of 2022. The revenue increase for the fourth quarter of 2023 was primarily due to$71.8 million in collaboration revenue related to our agreements with GSK and Pfizer. Total revenue for the year ended December 31, 2023 was$103.8 million , compared to$53.5 million for the year ended December 31, 2022. The revenue increase for the year ended December 31, 2023, was primarily due to the aforementioned collaboration revenue related to our agreements with GSK and Pfizer. - Research and development expenses for the fourth quarter of 2023 were
$16.6 million , compared to$15.1 million of research and development expenses for the same period in 2022. Research and development expenses for the year ended December 31, 2023 were$51.4 million , compared to$47.6 million for the year ended December 31, 2022. The increase in research and development expenses year-over-year was primarily due to increased clinical activity during the period related to the ongoing Phase 2a clinical trial of SPR720, offset by personnel-related costs. - General and administrative expenses for the fourth quarter of 2023 were
$6.4 million , compared to$6.5 million of general and administrative expenses for the same period in 2022. This year-over-year decrease was primarily due to changes in personnel-related costs, offset by increased professional and consulting fees. General and administrative expenses for the year ended December 31, 2023, were$25.6 million , compared to$36.5 million for the year ended December 31, 2022, with lower expenses in 2023 compared to 2022 primarily due to decreases in both personnel-related costs and professional and consulting fees. - As of December 31, 2023, Spero had cash and cash equivalents of
$76.3 million . Since the year-end closing of financials, the company received$23.8 million , the first tranche of the$95.0 million in development milestones from GSK. Based on its current operating plans, Spero expects that its cash and cash equivalents, together with other non-dilutive funding commitments, will be sufficient to fund its operating expenses and capital expenditure requirements into late 2025.
