Core Business Segments

Spero Therapeutics focuses on the development of novel antibiotics and therapies for bacterial infections. Its core business segments include:

1. Antibacterial Therapies

Spero’s primary focus is on developing treatments for bacterial infections, particularly those caused by MDR pathogens. Key products and candidates in this category include:

• Tebipenem HBr: An oral carbapenem antibiotic designed to treat complicated urinary tract infections (cUTIs), including pyelonephritis. Tebipenem HBr is a potential game-changer as it offers an oral alternative to intravenous (IV) carbapenems, which are typically used to treat severe bacterial infections.
• SPR720: A novel oral antibiotic candidate targeting non-tuberculous mycobacterial (NTM) infections. SPR720 is designed to address a significant unmet need in the treatment of NTM pulmonary disease.
• SPR206: A next-generation polymyxin antibiotic candidate for the treatment of MDR Gram-negative bacterial infections. SPR206 is being developed to provide a safer and more effective alternative to existing polymyxin antibiotics.

2. Research and Development (R&D)

Spero invests heavily in R&D to discover and develop new antibiotics and therapies. The company collaborates with academic institutions, government agencies, and industry partners to advance its pipeline of innovative treatments.

Business Model

Spero Therapeutics operates on a business model centered around the development and commercialization of novel antibiotics. The company generates revenue through:

• Collaborations and Partnerships: Spero collaborates with government agencies, such as the Biomedical Advanced Research and Development Authority (BARDA), and other organizations to fund its research and development efforts. These partnerships provide non-dilutive funding and support for the advancement of its pipeline.
• Licensing Agreements: Spero licenses its drug candidates to pharmaceutical companies for commercialization in specific markets, generating milestone payments and royalties.
• Product Sales: Once its drug candidates receive regulatory approval, Spero plans to generate revenue through the sale of its products.
