PHAXIAM Therapeutics Unveils Promising Results from PhagoDAIR Study

Today, PHAXIAM Therapeutics, a biopharmaceutical company focused on developing innovative solutions for severe bacterial infections, has shared the clinical outcomes of their PhagoDAIR I pilot study. This study highlighted an impressive 74% infection control rate in patients treated with a single intra-articular phage injection. These findings correlate with prior compassionate care reports and affirm the efficacy of phage therapy.

Overview of the PhagoDAIR Pilot Study

The PhagoDAIR study was designed as a randomized, multicenter, non-comparative, double-blind pilot trial focusing on patients with Staphylococcus aureus infections in hip or knee prostheses occurring over a month post-surgery. Aiming to include 64 patients, the study faced challenges due to stringent selection parameters, culminating in only 29 randomized patients, of which 26 were evaluated for clinical effectiveness.

Study Design and Results

The patient grouping in the study showed an unbalanced distribution, with 20 participants receiving phage therapy and only 9 in the placebo group. This discrepancy stemmed from stratification processes involving clinical centers that could only recruit a limited number of patients. All participants were provided standard care, including debridement, antibiotic therapy, and prosthesis maintenance, followed by randomization between phage therapy and placebo.

The primary goal was to assess the proportion of patients in each group free from infection after 12 weeks. A crucial aspect of the safety assessment confirmed the well-tolerated nature of the phage intervention.

An Encouraging Safety Profile and Infection Control

With 19 patients receiving phage treatment in the experimental arm, and 7 in the control group, the outcomes indicated that 14 out of 19 (74%) achieved effective infection control, compared to 5 out of 7 (71%) in the placebo arm. These results are remarkably consistent with previous compassionate cases involving phage therapy, estimated at a similar efficacy around 75% among approximately 60 patients.

Insights on the Upcoming GLORIA Phase II Study

As PHAXIAM moves towards the GLORIA Phase II clinical trial—the first global study of its kind—the company aims to expand upon the groundwork laid by the PhagoDAIR study. This comprehensive investigation will involve 100 patients with prosthetic joint infections and will include both randomization and a placebo-controlled approach. Patients will receive PHAXIAM anti-Staphylococcus aureus phages through three intra-articular injections coupled with a 12-week antibiotic treatment.

The Impact of Previous Studies on GLORIA

The accumulated knowledge and clinical data from PhagoDAIR play a pivotal role in enhancing the probability of success for GLORIA. As the inclusion criteria evolve, the study will target a much broader patient base, paving the way for more effective outcomes.

Approval and Future Directions

With FDA IND approval already secured, the GLORIA study is also undergoing evaluation by prominent European health authorities. Following all necessary approvals, the initiative aims to commence in several European nations and the United States, marking a significant milestone in phage therapy exploration.

Pascal Birman, PHAXIAM's Chief Medical Officer, expressed optimism regarding the findings, emphasizing the consistent results of phage treatment and its integration into broader clinical strategies.

Concluding Remarks from Medical Experts

Healthcare professionals, including Pr. Tristan Ferry, have continued to voice their support for the evolving methodology surrounding phage treatments, as evidenced by the encouraging data from the PhagoDAIR trial. With a consistent clinical activity rate and favorable outcomes for patients experiencing relapse, there remains a solid foundation for advancing phage therapy upstream into mainstream medical practices.

Frequently Asked Questions
