Recce Pharmaceuticals Announces Update on Phase I/II Clinical Trial for the Treatment of Burn Wound Infections


  • Broad spectrum antibiotic activity on bacterial burn wound infections with visible infection reduction <24 hours on all patients to date
  • All infections cleared within 5 days (acute) or 7 days (chronic); clinicians reducing treatment windows per protocol/positive patient indications
  • Burn wound infections consisted of Gram-positive and Gram-negative bacteria, including multi-drug resistant and ‘biofilm’ categorized forms
  • Update in-line with reaching clinical trial endpoints; patient recruitment on-going

SYDNEY, Australia, Dec. 07, 2021 (GLOBE NEWSWIRE) -- Recce Pharmaceuticals Ltd (ASX:RCE, FSE:R9Q) (the Company), the Company developing new classes of synthetic anti-infectives, is pleased to provide an update on its Phase I/II clinical trial for the treatment of burn wound infections.

The West Australian Health department sponsored clinical trial at Fiona Stanley Hospital is assessing the safety and efficacy of RECCE® 327 (R327) in patients with infected burn wounds under the Trial ID ACTRN12621000412831.

“We are highly encouraged by the initial success of R327 in this topical Phase I/II trial,” said Dr. Ed Raby, Study Investigator. Patients with burn wounds often suffer severe bacterial infections that are painful, prevent wound healing, and can even result in death if not properly treated. Because many of these bacteria are resistant to most available drugs, we are pleased by the potential in R327 offering a treatment option for patients in need.”

James Graham, Chief Executive Officer of Recce Pharmaceuticals, added, “We are pleased with the progress of our lead compound, R327, in patients harboring serious burn wound infections. This initial update builds upon strong pre-clinical data demonstrating fast and efficient killing activity against common and problematic bacterial strains, and we are excited for the potential of R327 in the clinic. We look forward to updating shareholders of further human clinical data points as this trial progresses.”

Characterization of swabs from participant burn wounds prior to treatment with R327 identified a wide range of pathogenic bacteria including, Gram-positive (Staphylococcus aureus1 and Staphylococcus lugdunensis) and Gram-negative (Pseudomonas aeruginosa2, Klebsiella pneumoniae3, Morganella morganii, Proteus vulgaris, Proteus mirabilis) bacteria, some of which are defined as multi-drug resistant and categorized as difficult to treat due to biofilms.

Clinicians have reported visible reductions in bacterial infection within the first 24 hours of R327 treatment among patients treated to date. Patients with acute infected wounds have indicated a complete clinical response, requiring no further treatment. As a result, clinicians have adopted a significantly shorter five (5) day treatment protocol. Patients with chronic or significant surface area wounds see a similar outcome by day seven (7). Treatment protocols for both groups of patients were initially proposed to comprise a 14-day period.

As is common in therapeutic activity on sensitive wound surfaces, patients noted a minor, brief stinging sensation as the solution reached the area of infection, which appeared to subside in line with a reduction in bacterial loads. No adverse effects or abnormalities have been reported among patients.

The study is on-going, with target patient enrolment/treatment expected early 2022, allowing full dataset reporting to follow.
