Introduction
Doribax, also known as doripenem, is a broad-spectrum carbapenem antibiotic used to treat severe bacterial infections, particularly in hospitalized patients. This article will delve into the recent clinical trials, market analysis, and future projections for Doribax.
Clinical Trials Overview
Safety Concerns and Label Changes
A significant update in the clinical trials of Doribax came in 2014 when the FDA approved label changes due to safety concerns. A three-year clinical trial was prematurely stopped in 2011 due to increased mortality and lower clinical cure rates in patients treated with Doribax compared to those treated with imipenem and cilastatin for ventilator-associated bacterial pneumonia. The trial showed a 28-day all-cause mortality rate of 23.0% in the Doribax arm versus 16.7% in the imipenem and cilastatin arm[1].
Approved Indications
Despite these concerns, Doribax remains safe and effective for its FDA-approved indications, which include the treatment of adults with complicated intra-abdominal infections and complicated urinary tract infections, including pyelonephritis[1].
Clinical Trial Data
In clinical trials for complicated urinary tract infections and complicated intra-abdominal infections, Doribax demonstrated efficacy. For example, in trials involving patients with complicated urinary tract infections, 52% of microbiologically-evaluable patients had complicated lower urinary tract infections, and 48% had pyelonephritis. Similarly, in trials for intra-abdominal infections, the most common anatomical site of infection was the appendix[4].
