Lakewood-Amedex Biotherapeutics Announces Positive Data for the Advancement of Lead Candidate, Nu-3, in Infected Diabetic Foot Ulcers

Key formulation, delivery and manufacturing steps completed in preparation for planned Phase 2 clinical trial

SARASOTA, Fla., May 18, 2026 /PRNewswire/ -- Lakewood-Amedex Biotherapeutics Inc., (NASDAQ: LABT, the "Company"), a clinical-stage biotechnology company advancing a novel class of potent, fast-acting, broad-spectrum antimicrobials for infectious diseases called the Bisphosphocin^® class, today announced positive data for its lead compound, Nu-3, as it advances towards a Phase 2 trial. Nu-3 is being developed as a topically delivered treatment for mildly infected diabetic foot ulcers (iDFU) designed to reduce the risk of antimicrobial resistance (AMR).

The Company has conducted drug substance (the active ingredient) manufacturing process development for a few members of the Bisphosphocin^® class and has completed several multikilogram scale under current Good Manufacturing Practices (cGMP) guidelines with high efficiency. In addition, process development advances have improved the cost of goods and have produced bulk drug substance with enhanced physical chemistry characteristics. The Company has also conducted drug product (the gel formulation) manufacturing process development and multikilogram quantities of the Nu-3 gel formulation have been manufactured under cGMP guidelines, and the product is suitable for use in clinical trials.

"Lakewood-Amedex Biotherapeutics has worked diligently to optimize formulation and manufacturing processes required to produce both the Bisphosphocin^® drug substances and drug products," said Kelvin Cooper, Ph.D., Chief Executive Officer at Lakewood-Amedex Biotherapeutics. "The Bisphosphocin^® class of compounds are modified nucleotide molecules with excellent aqueous solubility, potentially making them adaptable to a range of different drug product formulations and delivery methods, which could have significant potential in additional indications such as complicated urinary tract infection (cUTI) and pulmonary infections. We look forward to advancing the current Nu-3 gel formulation into a planned Phase 2 clinical trial targeting iDFU."

In key stability testing, the Company has shown that the Nu-3 bulk drug substance material is stable for at least five years, and further examinations of the Nu-3 formulation have shown the drug product to be stable for at least two years. In addition, initial testing for bioburden (the presence of viable microorganisms) and antimicrobial effectiveness has demonstrated that the drug product has undetectable bioburden levels for at least two years and does not require additional preservatives to maintain antimicrobial effectiveness.

The Bisphosphocin^® class of compounds has been shown in vitro to rapidly kill bacteria through a pH and concentration dependent destabilization of the bacterial cell membrane. This mechanism of action offers the potential to reduce the threat posed by antibiotic-resistant bacterial strains, including Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococci (VRE), and others.

About Nu-3
Nu-3 is Lakewood-Amedex Biotherapeutics Inc.'s lead product being developed for the topical treatment of mildly infected diabetic foot ulcers (iDFU). Nu-3 belongs to a novel class of antimicrobials being developed by Lakewood-Amedex Biotherapeutics Inc. called the Bisphosphocin® class, which possess a unique mechanism of action that enables rapid elimination of a broad spectrum of bacteria, including resistant pathogens and biofilms. Data from initial exploratory clinical trials with Nu-3 using subclinical doses did not reveal any safety signals and showed a trend of positive antimicrobial response and improved wound healing. Based on these results, the Company plans to conduct an initial Phase 2a safety and dose response study of Nu-3 followed by a placebo-controlled Phase 2b dose comparative study. This study is also designed to determine the most appropriate administration regimen for Nu-3 gel formation in mildly infected diabetic foot ulcers.
