Polyphor: First nosocomial pneumonia patient enrolled for Phase III murepavadin clinical trial

Polyphor today announced the enrollment of the first patient in its PRISM-UDR clinical trial, the second Phase III study for murepavadin (POL7080) for the treatment of hospital-acquired (HABP) and ventilator-associated bacterial pneumonia (VABP) due to Pseudomonas aeruginosa. Murepavadin is also being evaluated in the ongoing PRISM-MDR Phase III trial in patients with nosocomial pneumonia, which started in March 2018.

PRISM-UDR is a global Phase III multicenter, sponsor blinded, randomized, active-controlled, parallel-group, non-inferiority study of murepavadin combined with ertapenem in adult patients with nosocomial pneumonia due to Pseudomonas aeruginosa. The primary efficacy objective is to demonstrate non-inferiority (20% non-inferiority margin) of murepavadin compared to an anti-pseudomonal β-lactam-based antibiotic. The study was designed based on feedback from the U.S. Food and Drug Administration (FDA) and is agreed as the basis for a potential approval in the US. Eligible subjects with a high probability of nosocomial pneumonia due to Pseudomonas aeruginosa will be allocated at random to receive murepavadin or a comparator beta-lactam agent in a 1:1 ratio. The primary analysis population will comprise 210 subjects (105 subjects per arm) with nosocomial pneumonia confirmed to be due to Pseudomonas aeruginosa.

"The initiation of the PRISM-UDR clinical trial demonstrates our continued commitment to bringing forward this potential new treatment option for patients with nosocomial pneumonia due to Pseudomonas aeruginosa," commented Frank Weber, Polyphor Director and a.i. Chief Medical and Development Officer. "New therapeutic options are desperately needed, and we look forward to future clinical development milestones for murepavadin."
