Respirion Pharmaceuticals

Respirion Pharmaceuticals, established in 2018, is a clinical-stage biotechnology company with a sharp focus on therapies for respiratory diseases, particularly Cystic Fibrosis (CF). The company originated as a spinout from the Telethon Kids Institute in Perth, where its foundational product development was nurtured. The impetus for the company's creation came from Dr. Barry Clements, a pediatric respiratory clinician with over three decades of experience treating CF patients at Perth Children's Hospital. Frustrated by the limitations of existing treatments for persistent lung infections, his research into improving inhaled antibiotic efficiency formed the scientific bedrock of Respirion.

The company's core business revolves around the development and commercialization of novel drug candidates. Its primary market is the global Cystic Fibrosis patient population, which numbers approximately 70,000 worldwide. Respirion's business model is centered on advancing its lead product through rigorous clinical trials to gain regulatory approval and subsequently bring it to market, a process supported by significant funding from venture capital and health foundations. Key investors include Brandon BioCatalyst (through the Medical Research Commercialisation Fund) and the US Cystic Fibrosis Foundation, which have committed substantial funds to accelerate the clinical development program.

Respirion’s lead product is RSP-1502, an inhaled therapy designed to combat chronic Pseudomonas aeruginosa lung infections, a major cause of morbidity in CF patients. The treatment is a novel combination of tobramycin, a standard-of-care antibiotic, and a biofilm-disrupting agent. Bacteria in the lungs of CF patients often form protective biofilms, which render antibiotics less effective. RSP-1502's unique selling point is its ability to break down these biofilms, significantly enhancing the antibiotic's ability to kill the bacteria. An early clinical study demonstrated that this combination led to a dramatically greater reduction in bacterial load and a significant improvement in lung function compared to tobramycin alone. The therapy is administered using an efficient vibrating mesh nebulizer, reducing treatment time. The company is currently conducting a Phase 1b/2a clinical trial in the United States and Australia to further evaluate the safety and efficacy of RSP-1502.
