About Recce Pharmaceuticals Ltd Recce Pharmaceuticals Ltd (ASX: RCE, FSE: R9Q) is developing a New Class of Synthetic Anti- Infectives designed to address the urgent global health problems of antibiotic-resistant superbugs. Recce’s anti-infective pipeline includes three patented, broad-spectrum, synthetic polymer anti- infectives: RECCE® 327 (R327) as an intravenous and topical therapy that is being developed for the treatment of serious and potentially life-threatening infections due to Gram-positive and Gram-negative bacteria, including their superbug forms; RECCE® 435 (R435) as an orally administered therapy for bacterial infections; and RECCE® 529 (R529) for viral infections. Through their multi-layered mechanisms of action, Recce’s anti-infectives have the potential to overcome the processes utilised by bacteria and viruses to overcome resistance – a current challenge facing existing antibiotics. The World Health Organization (WHO) added R327, R435, and R529 to its list of antibacterial products in clinical development for priority pathogens, recognising Recce’s efforts to combat antimicrobial resistance. The FDA granted R327 Qualified Infectious Disease Product designation under the Generating Antibiotic Initiatives Now (GAIN) Act, providing Fast Track Designation and 10 years of market exclusivity post approval. R327 is also included on The Pew Charitable Trusts’ Global New Antibiotics in Development Pipeline as the sole synthetic polymer and sepsis drug candidate in development. Recce wholly owns its automated manufacturing, supporting current clinical trials. Recce’s anti- infective pipeline aims to address synergistic, unmet medical needs by leveraging its unique technologies.
