Overview of Spero Therapeutics Inc
Spero Therapeutics Inc is a clinical-stage biopharmaceutical company dedicated to developing novel therapeutic candidates to combat high unmet medical needs, especially in the treatment of multidrug-resistant (MDR) bacterial infections and rare diseases. As an innovator in the field, Spero leverages a culture of respect, action, collaboration, and transparency to foster groundbreaking approaches in antibiotic research and development. With a robust pipeline that includes both oral and intravenous treatment options, the company is focused on addressing critical gaps in current medical therapies.
Core Therapeutic Focus and Pipeline
The company’s research portfolio is centered on three primary investigational product candidates:
- Tebipenem HBr: An investigational oral carbapenem-class antibiotic designed specifically for adults, aimed at treating MDR Gram-negative infections. This product emphasizes ease of administration by offering a potential out-patient treatment approach to infections that are traditionally managed in hospital settings.
- SPR720: Initially developed as an oral antibiotic candidate focused on addressing rare conditions such as pulmonary non-tuberculous mycobacterial (NTM) infections. SPR720 exemplified the company’s commitment to targeting niche segments with significant unmet need, even though its development has been restructured based on emerging study data.
- SPR206: A next-generation, intravenously administered polymyxin designed for use in hospital settings. This investigational product is being evaluated as a potential therapy against MDR Gram-negative pathogens including strains that are resistant to conventional antibiotic treatments.
