EMV Capital CEO Dr. Ilian Iliev and Executive Chairman Nigel Brooksby joined Steve Darling from Proactive to discuss the company’s progress in advancing XF-73, an antimicrobial drug candidate designed to help prevent surgical site infections. The program represents an important step in addressing a significant healthcare challenge, particularly as hospitals and healthcare systems continue searching for more effective approaches to reduce infection risks and improve patient outcomes.
XF-73 is being developed as a first-in-class topical antimicrobial treatment intended to rapidly eliminate harmful bacteria before surgery. The therapy targets bacteria commonly found in the nasal cavity that can contribute to post-surgical infections and complications. Management highlighted that a previous Phase 2 clinical study demonstrated a 99.5% reduction in bacterial nasal carriage within just 24 hours among surgical patients, providing encouraging support for the treatment’s potential effectiveness.
The company acquired XF-73 and related intellectual property from Destiny Pharma in September 2025 through its Morai Acquisitions vehicle, which was subsequently renamed AMR Bio. Following the transaction, EMV Capital completed a funding round of approximately £1.3 million aimed at supporting the establishment and continued development of the new business.
Brooke explained that several important regulatory milestones are expected to drive progress for the program. Planned near-term activities include filing an Investigational New Drug application for XF-73 Nasal, preparing for a Phase 3 trial, qualifying Infectious Disease Product designation, and advancing discussions with the U.S. Food and Drug Administration. The company also announced that Cardinal Health has been appointed as AMR Bio’s U.S. regulatory agent to assist with FDA submission processes.
Beyond the United States, the company noted progress on international regulatory efforts. The United Kingdom’s Medicines and Healthcare Products Regulatory Agency has granted Accelerated Access status for XF-73 under its Innovative Licensing and Access Pathway, a designation designed to support the development and availability of promising healthcare technologies.
AMR Bio’s broader development plans include securing additional FDA guidance regarding the Phase 3 pathway, building manufacturing capabilities to support commercialization, and exploring partnership opportunities that could help accelerate market expansion and adoption.
The company also sees potential applications for the technology beyond surgical infection prevention. Future development could include topical and dermatological formulations targeting severe wounds, skin infections, diabetic ulcers, and trauma-related conditions, creating a potentially broader platform opportunity.
The commercial opportunity surrounding antimicrobial and infection prevention technologies remains significant. The global surgical site infection market was estimated at approximately $8.37 billion in 2025 and is projected to grow to around $17.95 billion by 2034. Within the United States alone, AMR Bio estimates that peak sales opportunities could exceed $1 billion annually across breast, cardiac, and orthopedic surgery patient populations.
