>>PolyMedix Announces Encouraging Interim Results From Multinational Phase 2 Clinical Trial With PMX-30063 Defensin-Mimetic Antibiotic
Efficacy and Safety Demonstrated in All Evaluated Dose Groups
First Clinical Study with New Class of Antibiotic in Patients with S. aureus ABSSSI Infections
Conference Call Today at 9:00 am ET
RADNOR, Pa., Dec. 7, 2011 (GLOBE NEWSWIRE) -- PolyMedix, Inc. (OTCBB:PYMX.OB - News), a biotechnology company focused on developing new therapeutic drugs to treat life-threatening infectious diseases and acute cardiovascular disorders, announced that an interim analysis of results from more than 80 patients enrolled in its Phase 2 clinical trial with PMX-30063 defensin-mimetic antibiotic, indicate that all dosing arms in the study were both safe and effective in treating patients with Acute Bacterial Skin and Skin Structure Infections (ABSSSI) caused by S. aureus. This is the first ever patient clinical efficacy study conducted with this new defensin-mimetic antibiotic class. PolyMedix is continuing to enroll patients and expects to complete the full trial in the first half of 2012.
Combined results from all patients enrolled in the four dosing arms showed:
• A combined clinical cure rate of 92%, with each of the four dosing arms (approximately 20 patients in each arm) having clinical cure rates ranging from 87% to 100%. Evidence of an early and sustained clinical cure is expected to be the primary endpoint for future Phase 3 pivotal trials for ABSSSI.
• Efficacy and safety support continued dosing for all study arms.
• All dose groups were safe and generally well-tolerated with no clinically significant differences observed between the groups.
Dr. Daniel Jorgensen, Chief Medical Officer of PolyMedix commented, "Observations to date from the interim analysis suggest that all three dosing regimens of PMX-30063 are effective and safe in treating patients with ABSSSI S. aureus infections. We are encouraged with the observations from this study, especially the minimal differences between dosing arms, which allowed for data analysis without unblinding the dose groups. With signs of all dosing arms working, we believe PMX-30063 could potentially have a very attractive therapeutic window and may warrant the evaluation of shorter treatment regimens in the future."
"PMX-30063 is the first, and to date only, compound in this new class of defensin-mimetic antibiotics that we are very proud to have discovered," said Nicholas Landekic, President and Chief Executive Officer of PolyMedix. "Unlike currently marketed antibiotics, our defensin-mimetic antibiotics are designed to kill bacteria utilizing a mechanism of action that is likely to evade bacterial resistance. These results are the first ever efficacy observations with a defensin-mimetic antibiotic and represent an important milestone for PolyMedix and the ongoing clinical development of PMX-30063 in its first indication for ABSSSI."
The multinational Phase 2 clinical trial is designed to evaluate the safety and efficacy of PMX-30063 in treating patients with ABSSSI due to either methicillin-susceptible (MSSA) or methicillin-resistant (MRSA) S. aureus. Up to 200 patients will be enrolled and randomized to receive either one of three 5-day dose regimens of PMX-30063 or daptomycin's approved 7-day dose regimen, which is the active control. Patients receiving PMX-30063 are being treated for 5 days and assessed for clinical and microbiologic response while on therapy (Day 3) and at the end of therapy (Day 7). Patients are then re-evaluated at day 10 to 15 for test of cure and at 4 weeks for safety follow up. This trial design incorporates the clinical assessments outlined in the most recent FDA Draft Guidance for ABSSSI.

About PMX-30063
PolyMedix's novel antibiotic compound, PMX-30063, is the first of a new class of antibiotics -- defensin-mimetics. PMX-30063 is a small-molecule designed to mimic the activity of human host-defense proteins (HDPs), the body's natural defense against bacterial infections. HDPs kill bacteria by directly targeting bacterial membranes and disrupting them. Widespread resistance to this mechanism of action has not developed despite millions of years of evolution. With PMX-30063 designed to mimic HDPs, we believe that resistance is also unlikely to evolve to this novel antibiotic, making PMX-30063 a potential solution to the growing problem of bacterial resistance. PMX-30063 has been tested in three Phase 1 clinical studies and is currently in a Phase 2 clinical trial to treat patients with Acute Bacterial Skin and Skin Structure Infections caused by S. aureus bacteria.<<
