PolyMedix Provides Updates on PMX-60056 Heptagonist Program

Planning Phase 2 Clinical Trial in Interventional Cardiology

Distinguished Scientists and Clinicians join Heptagonist Clinical Advisory Board

RADNOR, Pa.--(BUSINESS WIRE)-- PolyMedix, Inc. (OTC BB: PYMX), a biotechnology company focused on developing new therapeutic drugs to treat infectious diseases and acute cardiovascular disorders, has announced plans for a Phase 2 clinical trial of PMX-60056 in interventional cardiology, and the establishment of a focused Heptagonist Clinical Advisory Board (CAB). PMX-60056 is a synthetic small-molecule designed to reverse the anticoagulant activity of heparin and low molecular weight heparins (LMWH).

PolyMedix recently had an End-of-Phase 1 meeting with the United States Food and Drug Administration (FDA), the primary purpose of which was to seek advice from the FDA on the next steps for the clinical development of PMX-60056. Based on comments received, PolyMedix plans to study PMX-60056 in a Phase 2 clinical trial in Percutaneous Coronary Intervention (PCI) patients instead of next conducting a Phase 2 study in Coronary Artery Bypass Grafts (CABG), and anticipates filing a Phase 2 PCI protocol with the FDA in the upcoming weeks. Commencement of this Phase 2 clinical trial, which may occur as early as later this year or early next year, will depend on a variety of factors, including clearance of the protocol by the FDA, Institutional Review Board approvals at clinical study sites, and other regulatory processes, which can vary in duration. PolyMedix is evaluating the possibilities for additional Phase 2 clinical trials, such as reversal of LMWH, as well as a Phase 2 clinical trial in CABG patients in the future.

“We appreciate the FDA’s comments and value their advice, and are happy to have illumination for the path forward with PMX-60056,” commented Nicholas Landekic, President and CEO of PolyMedix. “We are pleased to be moving forward with plans for a Phase 2 study in patients. We look forward to applying what we have learned regarding the activity of PMX-60056 to now studying patients in the interventional cardiology setting, and to the continued development of PMX-60056 for both reversal of heparin and the low molecular weight heparins.”

PolyMedix has organized a dedicated Heptagonist Clinical Advisory Board (CAB) with a group of distinguished scientific and clinical experts. The CAB will actively advise PolyMedix on the future clinical development of PMX-60056.

About PMX-60056

PolyMedix’s heptagonist compound, PMX-60056, is a synthetic, small-molecule designed to reverse the anticoagulant activity of both heparin and low molecular weight heparins (LMWHs). Heparin is an intravenous anticoagulant used to prevent clots from forming during certain cardiothoracic and orthopedic surgical procedures. After these procedures, the anticoagulant activity of heparin is reversed in order to prevent post-operative bleeding. Protamine is presently the only agent available for this use. Protamine has many limitations, and we believe there is a major need for alternative heparin reversing agents which may be safer or easier to use. LMWHs are used in approximately 12 million patients annually for chronic treatment of thrombosis. Up to 20% of patients may experience bleeding complications. There is presently no FDA approved agent available to reverse the anticoagulant activity of LMWHs. PolyMedix believes PMX-60056 pre-clinical and clinical data suggest potential safety and other advantages over protamine, as well as an opportunity to be the first reversing agent for LMWHs.

About PolyMedix, Inc.

PolyMedix is a publicly traded biotechnology company focused on the development of novel drugs for the treatment of serious infectious diseases and acute cardiovascular disorders. PolyMedix uses a rational drug design approach to create non-peptide small molecule drug candidates. PolyMedix’s lead antibiotic compound, PMX-30063, is currently in Phase 2 clinical trials. PMX-30063 is a small molecule that mimics the mechanism of action of human host defense proteins, a mechanism that is distinct from currently approved antibiotic drugs and is intended to make bacterial resistance unlikely to develop. PolyMedix plans to develop this compound for serious systemic Staphylococcal infections, including methicillin resistant Staphylococcus aureus (MRSA). PolyMedix’s lead heptagonist compound, PMX-60056, has completed Phase 1 testing and is being developed to reverse the anticoagulant activity of both heparin and low molecular weight heparins (LMWH). PolyMedix believes that PMX-60056 could potentially be a safer and easier to use anticoagulant reversing agent, with broader activity, than the currently approved therapy for reversing heparin and LMWH. In addition to its small molecule therapeutics, PolyMedix has polymeric formulations with the same mechanism of action as PMX-30063, PolyCides™, which are intended for use in antimicrobial biomaterials applications s additives to paints, plastics, and textiles to create self-sterilizing products and surfaces.
