Job Description

About Us

Spero Therapeutics (Nasdaq: SPRO) is a multi-asset clinical stage biopharmaceutical company in Cambridge, Mass. We are highly committed to advancing novel treatment approaches for bacterial infections with a world-class team of biotechnological and biopharmaceutical experts. The company has a pipeline of novel and highly differentiated antibacterial and rare disease product candidates focused on the unmet needs of patients with multi-drug resistant (MDR) bacterial infections. Spero’s lead product candidate, Tebipenem HBr, is an oral carbapenem currently being evaluated in a pivotal Phase 3 clinical trial for the treatment of complicated urinary tract infections. Spero is also advancing SPR720, its oral antimicrobial agent in development for the treatment of nontuberculous mycobacterial (NTM) pulmonary disease, a rare orphan disease. Spero’s third product candidate, SPR206, is an IV-administered agent being developed as an innovative option to treat MDR Gram-negative bacterial infections.

We sincerely believe that our novel product candidates will have meaningful impact on patient health and significant commercial applications for the treatment of MDR infections in both the hospital and community settings.
