SYDNEY, Australia, April 10, 2024 (GLOBE NEWSWIRE) -- Recce Pharmaceuticals Ltd (ASX: RCE, FSE: R9Q) (Recce or the Company), a leading developer of a new class of synthetic anti-infectives, today provided a business update highlighting various ongoing activities and progress made since the Annual General Meeting held on November 8, 2023.

Detailed Update:

Progress of R327 across Multiple Indications
(UTI/Urosepsis, DFI, Topical Wounds, SAS-A)

Phase I/II UTI/Urosepsis Trial – R327 Achieving Minimum Inhibitory Concentration (MIC)

The Company is making significant strides in its Phase I/II trial for UTIs and urosepsis. Recent clinical urine samples have indicated promising MIC activity, suggesting that fast infusion of R327 leads to concentrations capable of blocking the growth of bacteria in urine, which is relevant for the treatment of patients with UTIs and urosepsis, in a safe and tolerable manner. This promising finding has prompted the Company to increase the dosage of R327 in this Phase I/II trial to its highest level yet, at a rate of 4,000mg infused over 30 minutes, which is expected to begin by the end of Q2 2024. This escalation reflects the significant progress surrounding R327's potential to address critical medical needs in the treatment of UTIs and urosepsis.

DFI Efficacy Achieved: Expansion of Phase I/II DFI Clinical Trial

Recce is actively pursuing an expansion of its clinical trial sites for its Phase I/II trial evaluating R327 in patients with DFIs, with notable sites identified and expected to come online during the present quarter, including one of the largest and most comprehensive regional health services in Australia based out of Victoria, and a world-class private hospital in Western Australia.

This strategic initiative aims to access a greater patient population, enhancing the diversity and depth of clinical data gathered. By forging collaborations with these esteemed institutions, the Company continues to demonstrate its commitment to advancing medical research and delivering innovative solutions that could potentially transform patient outcomes.

The Company is actively advancing its latest international expansion in Indonesia for a DFI clinical trial, moving steadily towards the initiation of a Phase III registrational trial scheduled to commence in Q3 2024.

R327 works and keeps on working with repeated use: tested in more than 300 Strains of Bacterial Pathogens – Effective Against All

The Company continues to work with leading experts dedicated to the discovery and development of innovative technologies, Linnaeus Bioscience, where they have tested R327 against more than 300 strains between the ESKAPE group of pathogens (198 Gram-negative and 111 Gram-positive bacteria strains). Chief Operations Officer of Linnaeus, Hannah Tsunemoto, Ph.D., led the experiments against these pathogens and commented, “R327 is effective against all strains tested at MICs.”

Gram-positive representatives  Gram-negative representatives
BacteriaStrains BacteriaStrains
Enterococcus spp.33 K. pneumoniae38
S. aureus65 A. baumannii53
Enterobacter spp.13 P. aeruginosa63
Total198 E. coli40

More than 95% of the strains tested were clinically isolated from a variety of sources, including but not limited to wounds, blood, urine, and sputum (phlegm).

Furthermore, in a 31-day sub-MIC serial exposure study, R327 was tested against a Multi-Drug Resistant (MDR) strain of Escherichia coli (E. coli) and showed no evidence of induced resistance to R327.

Submission of Investigational New Drug (IND) Application with the US FDA expected in H2 2024 for U.S. trial initiation in H1 2025

The Company has been making significant strides in preparing for an investigational new drug (IND) application with the U.S. Food and Drug Administration (FDA). One of the pivotal initiatives contributing to this progress is the successful ongoing Phase I/II UTI/Urosepsis rapid infusion clinical trial. The completion of the Phase I trial marked a crucial milestone for the Company, providing valuable data on the safety and tolerability of R327 required as part of the IND Application dossier.

As the Company continues to generate promising interim data from its Phase I/II UTI/Urosepsis clinical trial on both safety and efficacy, R327 is showcasing its capability to be administered over multiple fast infusion times, highlighting the potential for a ground-breaking treatment on the first patient presentation in any medical setting. These achievements collectively position Recce on track with its upcoming IND application, underscoring the company's dedication to bringing novel therapies to market swiftly and responsibly.

The Company expects to open a second IND application for all topical work conducted soon after the intravenous (IV) IND application.

Government/Private Enterprise Partnerships and Presence in the USA

Recce has been actively pursuing various grant applications and submissions, particularly in government antimicrobial resistance (AMR) initiatives and military and health security.

U.S. Department of Defense: Recommended for $2.2M Grant Funding

As a result of the Company's efforts in the military sector, the U.S. Department of Defense has recommended R327 Gel (R327G) as a topical treatment for burn wound infections for grant funding of $2.2 million.

Once awarded, the funding will enable the Company to accelerate the development and evaluation of R327G and evaluate it as a gel-based treatment to rapidly resolve burn wound infections and minimize the onset of bacteremia complications, such as sepsis. This milestone emphasizes the Company’s significant contributions to military health research. Recce expects funding to be received in H1 2024.

Biomedical Advanced Research and Development Authority (BARDA) Presentation

Recce delivered a company presentation at the request of the U.S. Biomedical Advanced Research and Development Authority (BARDA), further strengthening its relationship and collaboration with U.S. governmental organizations.

BARDA has specific areas of interest that it focuses on for funding, where R327 fits into two categories: Antimicrobials (3.1 Multi-drug resistant Bacteria and Biothreat Pathogens) and Burn and Blast Medical Countermeasures (6.4 Non-Autologous Topical Products for Acute bacterial skin and skin structure infections). The presentation was well received and attended by members of the U.S. government from respective military fields.

WA and NSW Government Sponsor Recce for BIO International Convention 2024

The BIO International Convention is the largest and most comprehensive event for biotechnology, representing the full ecosystem of biotech with over 20,000 industry leaders from across the globe. As part of the Company’s national government initiatives, Recce has been successfully selected to be part of the WA and NSW delegation at BIO 2024, highlighting its regional support and recognition within the biopharmaceutical community. These initiatives collectively demonstrate Recce's dedication to advancing innovative solutions in healthcare through strategic collaborations and impactful research endeavours.
