Core Business and Product Pipeline
Spero Therapeutics specializes in the development of novel antibiotics and anti-infective therapies aimed at combating MDR Gram-negative infections and rare diseases. Its diverse product pipeline reflects a strategic focus on both oral and intravenous formulations, designed to improve patient outcomes and reduce reliance on prolonged hospital stays.
