Study Summary

The primary purpose of this study is to assess the efficacy of oral TBP-PI-HBr as compared with intravenous (IV) imipenem-cilastatin with respect to the overall response (combined clinical cure plus microbiological eradication) at the Test-of-Cure (TOC) visit in hospitalized adult participants (greater than or equal to (≥)18 years of age) with cUTI or AP.

Primary Outcome

Overall response includes combined clinical cure plus microbiological eradication. Clinical cure is defined as a complete resolution or significant improvement of signs and symptoms of cUTI or AP present at baseline and no new symptoms, such that no further antibacterial therapy is warranted, and participant is alive. Microbiological eradication (favorable microbiological response) is defined as a reduction of baseline uropathogens to \<10\^3 CFU/mL and negative repeated blood culture if blood c
