Investigational Treatments for Significant Unmet Medical Needs

Our Mission

Spero Therapeutics is dedicated to delivering differentiated medicines to help patients suffering from rare diseases and multidrug-resistant (MDR) bacterial infections.

Our Vision

At Spero Therapeutics, it is our hope to advance novel treatments for rare diseases and MDR bacterial infections.

Since our inception in 2013, we have been steadfast in our commitment to pioneering superior approaches for bacterial infections. Our founding was a response to the urgent need to combat severe infections and the escalating global crisis of antibiotic resistance. Our pipeline targets areas where approved therapies are scarce, or where the prevailing standards of care are suboptimal.

Spero Team

Our Experienced Team

Led by a management team with extensive experience and scientific talent, Spero is dedicated to delivering differentiated medicines that help patients suffering from rare diseases and MDR bacterial infections.

A Team Focused on Delivering Hope

Our team is fueled by a passion for the communities we serve and guided by the profound meaning of the Latin word “spero,” which encapsulates our vision: to bring hope to patients and caregivers alike who are grappling with the challenges of serious diseases. Hope is not just a word in our name, it is the driving force behind everything we do. The Latin phrase "dum spiro spero" translates to "While I breathe, I hope."

Spero Therapeutics was founded in 2013 and has been recognized multiple times as one of Boston’s Best Places to Work (2024, 2021, and 2020) by the Boston Business Journal.
