Argent BioPharma Limited Argent BioPharma Limited (ASX:RGT; LSE:RGT.L) is a clinical-stage biopharmaceutical company that develops and markets innovative nano-engineered therapeutics targeting the central nervous system and autoimmune disorders; its pipeline includes CimetrA in phase IIB trials for acute lung injury and ARDS, CannEpil in phase I trials for refractory epilepsy, CogniCann in phase IIA trials for dementia and Alzheimer's symptomatic relief, preclinical Irnican for glioblastoma multiforme, and RGAI03MW01 for chronic wound treatment. The company employs advanced nanotechnology and polypharmacology via its in-house R&D platform to create multi-targeted therapies aimed at enhancing efficacy and reducing side effects, with investigational medicinal products accessible through early patient programs in the UK, USA, Europe, and Australia. Founded in 2014 and headquartered in Subiaco, Australia, Argent BioPharma operates globally with a focus on immunology and neurology, including cannabinoid-based APIs supplied to institutions like Slovenia's University Medical Centre Ljubljana for drug-resistant epilepsy and collaborations such as with SINTEF for antimicrobial wound therapies. In November 2025, the company secured an A$11 million financing facility from C/M Capital, enabling completion of its US$15 million acquisition of AusCann Group assets—including Neuvis oral drug delivery technology, CannPal's epilepsy data and IP, and an EU-GMP cannabinoid facility—while gaining a 19.99% stake in Germany's ECC Pharm for distribution access; this supports expansion into North and South America and a potential US dual listing. Recent leadership changes feature Roby Zomer transitioning to Non-Executive Chairman, Andrew Chapman appointed as Executive Director, and board adjustments including Gary Hermon's departure, positioning the firm for accelerated commercial development.
