SYDNEY Australia, 30 March 2022: Recce Pharmaceuticals Ltd (ASX:RCE, FSE:R9Q) (the Company), the Company developing New Classes of Synthetic Anti-infectives, is pleased to report Phase I intravenous (IV) clinical trial of RECCE® 327 (R327) Cohort Four at 1,000mg (twenty-fold increase on cohort one 50mg dose), indicating a good safety and tolerability profile among 10 healthy male subjects.

James Graham, Chief Executive Officer of Recce Pharmaceuticals Ltd said, “Achieving a dosing level of 1,000mg is another significant milestone for the Company. Indicating R327 to be safe and well tolerated at a twenty-fold increase of the initial dosing level of 50mg is pleasing, not only for the unmet medical need of sepsis, but so too for synergies across our wider-infectious disease portfolio.”
