iSONEP Phase 1 Results Highlighted at Three Major Scientific Meetings

Various Abstracts Touting iSONEP as a Novel Potential Therapy for Wet AMD and RPE Detachment Accepted for Presentation at Key Ophthalmology Meetings

SAN DIEGO, CA--(Marketwire - September 9, 2010) -  Lpath, Inc. (OTCBB: LPTN), the category leader in bioactive-lipid-targeted therapeutics, announced that abstracts were accepted for presentation at three key ophthalmology meetings in North America. The presentations showed the encouraging data generated from Lpath's Phase 1 trial with iSONEP and concluded that iSONEP holds potential as a novel therapy for wet AMD and RPE detachment.

Thomas Ciulla, M.D. of the Midwest Eye Institute, presented an abstract titled, "A Phase 1 Investigation of iSONEP, a Sphingosine-1-Phosphate Monoclonal Antibody, for Wet AMD in a Subset of Subjects with PED," during a poster session at the American Society of Retinal Specialists held August 28 to September 1 in Vancouver, Canada. (PED is a persistent complication of wet AMD and is often referred to as "RPE detachment.")

Dr. Ciulla's poster drew the following conclusions, based on results from Lpath's iSONEP Phase 1 clinical trial:

  • iSONEP was well tolerated in all subjects at doses up to 1.8 mg, and a maximum tolerated dose was not reached;
  • Out of ten subjects that had potential to show biologic activity, eight showed signs of biological activity;
  • Several subjects experienced substantial regression of the underlying CNV lesion;
  • S1P (the bioactive lipid that iSONEP binds to and neutralizes) appears to be a mediator in the pathogenesis of wet AMD;
  • iSONEP has biologic activity in this subject population and holds promise as a new therapeutic agent; and
  • 100% of subjects with PEDs (two of two) resolved completely with a single injection of iSONEP by Day 45.

Patients with PED were excluded from Lucentis's MARINA and ANCHOR Phase 3 trials, and it is generally understood that Lucentis and other anti-VEGF therapies typically do not resolve PEDs, especially with a single dose. 

Dr. Ciulla stated: "Although limited in number, the two subjects with a PED at study entry showed remarkable improvement with a single injection of iSONEP, at fairly low doses (0.2mg and 1.0mg, respectively). There was no need for further anti-VEGF treatment for at least three months in both cases. iSONEP may indeed have potential as a new therapeutic agent in the treatment of PED."

According to Scott Pancoast, CEO of Lpath, "Lpath plans to further investigate the efficacy of iSONEP in a follow-on trial with 20-30 subjects that have PEDs. There is clearly a significant unmet need here and given that about 20% of wet AMD patients have a PED, the market opportunity exceeds $2 billion per year."

This poster presentation follows on the heels of a podium presentation given by Glenn Stoller, M.D., the head of Lpath's ocular division, at the 2010 Annual Meeting of ARVO (the Association for Research in Vision and Ophthalmology) in Ft. Lauderdale this past May titled, "iSONEP™, an Anti-S1P Monoclonal Antibody for Investigation in Exudative AMD: Results from a Phase 1 Prospective Open-Label Dose-Escalating Multi-Center Study." To a sizeable audience, Dr. Stoller reviewed the scientific basis for targeting S1P and the encouraging results of the iSONEP trial. He ended by concluding that iSONEP holds considerable promise as a potential therapeutic agent.

In addition, Michael J. Tolentino, M.D., the director of clinical research at the Centre for Retina and Macular Disease in Winter Haven, Florida, will review iSONEP phase 1 results at a podium presentation at The Retina Society annual meeting in San Francisco on September 26 during a session entitled, "Pediatrics, Genetics, and Novel Therapies." 

Pancoast noted, "Lpath plans a second, larger trial to investigate the efficacy of iSONEP -- in as many as 120 patients without PEDs -- that will help determine how to position iSONEP in the broader wet AMD market, which is projected to include over five million patients by the year 2025."
