Qpex Biopharma Announces Presentations on Phase 1 and Nonclinical Data on Three Clinical Stage Oral and IV Products Targeting Antibiotic-Resistant Bacterial Infections at 2022 ID Week Meeting

 

SAN DIEGO, October 17, 2022 – Qpex Biopharma today announced that clinical and preclinical data on its portfolio of clinical stage investigational antibiotic programs will be featured in several presentations at the upcoming 2022 ID Week Meeting in Washington, DC on October 19-23.

The presentations will describe progress on three Qpex investigational products that the recent WHO pipeline analysis identified as addressing drug-resistant pathogens for which there is a critical need for new drugs. 

In addition to clinical data, microbiological results with the beta-lactamase inhibitor xeruborbactam in combination with multiple companion beta-lactams from comparative head-to-head studies against other marketed and investigational IV and oral products using recent clinical isolates of multi-drug resistant gram-negative bacteria will be presented.

“These studies show that the microbiological profile of our ultra-broad-spectrum beta-lactamase inhibitor xeruborbactam in combination multiple beta-lactams exceeds that for other investigational or marketed agents,” stated Michael Dudley, PharmD, FIDSA, president and chief executive officer of Qpex Biopharma. “We will also provide the first presentation of clinical results and PK-PD data from our ORAvance product that delivers xeruborbactam as an oral prodrug with the oral cephalosporin ceftibuten that is being investigated for potential once-daily treatment of certain gram-negative infections, including those due ESBL- and carbapenemase-producing Enterobacterales.” 

ID Week 2022 is the joint annual meeting of the Infectious Diseases Society of America (IDSA), Society for Healthcare Epidemiology of America (SHEA), the HIV Medical Association (HIVMA), the Society of Infectious Diseases Pharmacists (SIDP), and the Pediatric Infectious Diseases Society (PIDS). The meeting will be conducted in person in Washington, DC and online. Further information may be found at https://idweek.org.

About the Qpex Biopharma Pipeline

Qpex Biopharma has three clinical-stage programs focused on the treatment of extended-spectrum beta-lactamase (ESBL) and carbapenemase-producing pathogens that the CDC considers serious or urgent antimicrobial resistance threats, including Acinetobacter spp., Pseudomonas aeruginosa, and Enterobacterales. The World Health Organization (WHO) has prioritized development of new treatments for these pathogens. Qpex’s clinical-stage portfolio comprehensively addresses patient needs in both the inpatient and outpatient settings and includes:

  • OMNIvance®: an IV-administered xeruborbactam-based product with best-in-class coverage of key pathogens, including carbapenem-resistant Acinetobacter, Enterobacterales and Pseudomonas

  • ORAvance™: an orally-administered combination product that delivers xeruborbactam to treat infections that occur in the outpatient and community setting caused by drug-resistant gram-negative bacteria, including fluoroquinolone-, cephalosporin-, or carbapenem-resistant Enterobacterales.

  • QPX9003: a next-generation, IV-administered synthetic lipopeptide with an enhanced therapeutic profile designed to focus on highly drug-resistant infections caused by Pseudomonas and Acinetobacter.
