Spero Therapeutics Announces Positive Phase 3 Clinical Trial Results From ADAPT-PO

On August 8, Spero Therapeutics, Inc. (SPRO) announced positive topline results from its Phase 3 clinical trial.

The results showed that Spero’s oral treatment was statistically non-inferior to intravenous (IV) ertapenem treatments. This is the first ever trial of an entirely oral treatment for patients with cUTI.
