Entasis' (ETTX) Phase III Study on Infection Drug Meets Goal

Read MoreHide Full Article

Entasis announced positive top-line data from the phase III ATTACK study evaluating its investigational intravenous (IV) drug, sulbactam-durlobactam (“SUL-DUR”), in patients having infections caused by Acinetobacter baumannii.

The ATTACK study evaluated the efficacy and safety of SUL-DUR in comparison with colistin in carbapenem-resistant Acinetobacter (“CRAB”) patients in 17 countries. The study met the primary endpoint of 28-day all-cause mortality in CRAB patients, demonstrating statistical non-inferiority over colistin.

Entasis also reported that participants administered SUL-DUR exhibited a favorable safety profile over colistin including a statistically significant reduction in nephrotoxicity.

Shares gained 4.2% on Oct 19. In fact, the stock has rallied 31.2% so far this year against the industry’s 16.6% decline.

Please note that SUL-DUR is a combination of sulbactam and durlobactam, an IV β-lactam antibiotic and a novel broad-spectrum IV β-lactamase inhibitor, respectively, developed to treat infections caused by Acinetobacter baumannii, including CRAB.

The company has also partnered with Zai Lab (ZLAB - Free Report) to develop and commercialize the drug in Australia along with multiple Asian countries including mainland China as well as Japan.

We inform investors that Acinetobacter is a gram-negative pathogen that infects critically ill patients. While the pathogen causes severe pneumonia and bloodstream infections, it can also infect the skin and urinary tract. The infections caused by Acinetobacter also develop multidrug resistance.

Currently, there are limited treatment options for people suffering from Acinetobacter. Per company estimates, more than 300,000 hospital-treated CRAB infections exist annually across the United States, Europe, the Middle East and China. Potential approval and successful commercialization of the drug would boost revenue prospects for the company in the long term. It anticipates the submission of a new drug application with the FDA in mid-2022.
