SYDNEY, Australia, Feb. 08, 2022 (GLOBE NEWSWIRE) — 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 three at 500mg (tenfold increase on cohort one 50mg dose), indicating a good safety and tolerability profile among seven healthy male subjects.

“Indications of R327 being safe and well tolerated at 500mg IV is a wonderful milestone for the Company,” said James Graham, Chief Executive Officer of Recce Pharmaceuticals. “These results are an excellent outcome for this clinically-invasive method of administration, with a few additional participants to strengthen a compelling safety profile, and serves well for regulatory and synergistic program potential.”

Cohort Three (R327 – 500mg) – Demonstrated Safety and Tolerability
R327 was indicated to be safe and well tolerated at 500mg with no clinically significant changes in vital signs or adverse events associated with R327.

The Phase I trial is an ascending dose, randomized, placebo-controlled, parallel, double-blind, single-dose study being conducted at Adelaide’s CMAX clinical trial facility. The study is evaluating the safety and pharmacokinetics of R327 in 7-10 healthy subjects per dose, across eight sequential dosing cohorts of 50-16,000mg (Trial ID ACTRN12621001313820). The study is on track to have all Phase I dosing complete by Q2 2022.

According to PEW Charitable Trusts global antibiotic pipeline review, R327 is the only clinical-stage new class of antibiotic in the world being developed for sepsis, the largest unmet medical need in human health.¹

Recce’s anti-infective pipeline includes three patented, broad-spectrum, synthetic polymer anti-infectives: RECCE^® 327 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 as an orally administered therapy for bacterial infections; and RECCE^® 529 for viral infections. Through their multi-layered mechanisms of action, Recce’s anti-infectives have the potential to overcome the hypercellular mutation of bacteria and viruses – the challenge of all existing antibiotics to date.
