Peptilogics Presents Data Demonstrating Antimicrobial Activity Against Difficult to Treat Bacterial Pathogens of Engineered Peptide PLG0206

PITTSBURGH--(BUSINESS WIRE)-- Peptilogics, a clinical stage biotech company engineering peptide therapeutic solutions for patients with life-threatening diseases, presented preclinical data from its peptide, PLG0206, at the ASM/ESCMID Joint Conference on Drug Development to Meet the Challenge of Antimicrobial Resistance. Data presented demonstrate activity of PLG0206 against multi-drug resistant pathogens and suggest that this novel antimicrobial peptide could potentially address difficult to treat bacterial infections.

The poster, titled “Activity of the novel engineered antimicrobial peptide PLG0206 against non-fermenting Gram-negative rods,” highlights data investigating PLG0206 against isolates Acinetobacter baumannii, Pseudomonas aeruginosa and Stenotrophomonas maltophili present in skin, urinary, blood, intra-abdominal and respiratory infections. Results demonstrate that PLG0206 was active against all tested isolates and retained activity against multi-drug resistant (MDR) strains, suggesting that the unique mechanism of action of PLG0206 can overcome the drug-resistance mechanisms found in these MDR strains. The poster presented at the joint meeting hosted by the American Society for Microbiology (ASM) and European Society of Clinical Microbiology and Infectious Diseases (ESCMID) is available on the company website.

“Infections caused by A. baumanni, P. aeruginosa, and S. maltophilia are difficult to treat especially when they are multi-drug resistant,” said David Huang, M.D., Ph.D., Chief Medical Officer of Peptilogics. “The findings outline the promising activity observed with PLG0206 against prominent and difficult-to-treat bacterial pathogens including MDR strains, and we look forward to continuing to evaluate its activity against these and other bacterial pathogens that can cause life-threatening diseases.”

About PLG0206

PLG0206 is an investigational, broad-spectrum, non-traditional antibiotic peptide therapeutic currently in Phase 1b clinical development in patients undergoing debridement, antibiotics and implant retention (DAIR) surgery for the treatment of Prosthetic Joint Infection (PJI) occurring after total knee arthroplasty (TKA). PLG0206 has the potential to rapidly target bacteria and persistent pathogens that produce biofilm and evade conventional antibiotics. It was engineered with a unique mechanism of action to target and disrupt bacterial cell membranes, without causing lysis or targeting human cell membranes at therapeutic doses, thereby reducing the potential for inflammation and cytotoxicity. In both in vitro and non-clinical studies, PLG0206 has demonstrated potent activity against both Gram positive and Gram negative antibiotic resistant bacteria with a low risk of developing resistance to PLG0206. PLG0206 has been granted FDA Orphan Drug designation and Fast Track designation for the treatment of PJI and has also been designated as a Qualified Infectious Disease Product (QIDP).

About Periprosthetic Joint Infection (PJI)

Joint replacement is the most common operative procedure with seven million hip and knee replacements anticipated globally in 2030. PJI is the most common complication of joint replacement surgery and, if diagnosed with PJI, patients currently require an average of three surgeries to treat. With up to 60% recurrence and a five-year mortality of 25% associated with this condition, PJI is a catastrophic and growing problem with no effective therapeutic solution. The disease also leads to a substantial economic burden, where in the U.S. the average per patient cost is $500,000 to treat PJI, making this a major challenge for hospitals and payers alike.
