Qpex Biopharma to Present its Anti-infective Portfolio at IDWeek 2019

SAN DIEGO, September 25, 2019 –Qpex Biopharma today announced scientific presentations on its investigational anti-infectives at the IDWeek 2019 Conference to be held October 2-6 in Washington, DC.

Qpex scientists and external collaborators will be making the first public presentations on QPX9003, a next generation polymyxin antibiotic for multi-drug resistantAcinetobacter and Pseudomonas aeruginosa. In addition, they will present new data on the ultra-broad-spectrum beta-lactamase inhibitor QPX7728, focusing on its first-in-class properties as an inhibitor with potent activity with multiple beta-lactam antibiotics in Acinetobacter and Pseudomonas, as well as in Enterobacteriaceae that produce serine and metallo beta-lactamases. 

“We are pleased to report new data at IDWeek on our clinical candidates that demonstrate compelling preclinical properties as best-in-class agents forAcinetobacter, Pseudomonas, and Enterobacteriaceae,” said Michael Dudley, PharmD, FIDSA, President and CEO of Qpex Biopharma. “We welcome the opportunity to engage with the infectious disease community on the excellent progress of these programs as part of our ongoing portfolio collaboration with BARDA,”he added.  

Three poster presentations on the microbiological properties of QPX7728, and two posters on the microbiological properties and preclinical pharmacology of the clinical candidate QPX9003 will be presented by Qpex scientists and external collaborators.  Data show that QPX7728 has potent inhibition of clinically important beta-lactamases from Classes A, B, C, and D that are often present in multi-drug resistant (MDR)Acinetobacter, Pseudomonas, and Enterobacteriaceae. Notably, QPX7728 is active in strains of carbapenem-resistant Enterobacteriaceae (CRE) with resistance to ceftazidime-avibactam. The two posters on QPX9003 will show its improved potency and therapeutic index for Acinetobacter and Pseudomonas aeruginosa in animal models over polymyxin B.
