Data are positive from the from RECAPTURE 1 and 2 phase 3 studies, which evaluated the antibiotic ceftazidime-avibactam (Avycaz, Allergan) as a treatment for adult hospitalized patients with complicated urinary tract infections (cUTI), according to a press release on the studies from Allergan.

RECAPTURE 1 and RECAPTURE 2 are phase 3, randomized, multi-center, double-blind, double-dummy, parallel-group, comparative studies to determine the efficacy, safety, and tolerability of Avycaz vs. doripenem in the treatment of cUTI in hospitalized adults. 

The co-primary endpoints include: (1) symptomatic resolution of UTI-specific symptoms except flank pain and resolution of, or improvement in, flank pain based on the patient-reported symptom assessment response at the day 5 visit, and (2) proportion of patients with both a symptomatic resolution of UTI-specific symptoms at test of Cure (TOC) visit and a favorable microbiological response at TOC.

The co-primary analysis was conducted in the Microbiological Modified Intent-to-Treat (mMITT) population and the non-inferiority margin was 10%.

In both studies, Avycaz met the objective of statistical non-inferiority compared to doripenem for both co-primary endpoints, according to the press release. 

The lower and upper bounds of the 95% confidence interval for the difference (CAZ-AVI – doripenem) in the percentage of patients for (1) were -2.39% and 10.42% respectively and for (2) were 0.30% and 13.12% respectively.

Allergan officials said they plan to submit this data as a supplemental New Drug Application (sNDA) to the Food and Drug Administration (FDA) by the end of 2015.
