Excerpt from the Press Release:

CAMBRIDGE, Mass., Sept. 08, 2020 (GLOBE NEWSWIRE) — Spero Therapeutics, Inc. (Nasdaq: SPRO), a multi-asset clinical-stage biopharmaceutical company focused on identifying, developing and commercializing treatments in high unmet medical need areas involving multidrug-resistant (MDR) bacterial infections and rare diseases, today announced positive topline results from ADAPT-PO, the pivotal Phase 3 clinical trial evaluating Spero’s oral antibiotic candidate, tebipenem HBr, for the treatment of adults with complicated urinary tract infection (cUTI) and acute pyelonephritis (AP). Topline data from the trial demonstrate that oral tebipenem HBr was statistically non-inferior to intravenous (IV) ertapenem in the treatment of patients with cUTI and patients with AP.

The global Phase 3 ADAPT-PO clinical trial evaluated the safety and efficacy of oral tebipenem HBr versus IV ertapenem for the treatment of adults with cUTI or AP. Results demonstrate that tebipenem HBr was non-inferior compared to ertapenem with respect to the trial’s primary endpoint, overall response (combined clinical cure plus microbiologic eradication) at the test-of-cure (TOC) visit in the microbiological-intent-to-treat (micro-ITT) population.
