Lpath Granted Key U.S. Patent Related to Ocular Drug Program, iSONEP

SAN DIEGO, Jan. 22, 2014 /PRNewswire/ -- Lpath, Inc. (NASDAQ: LPTN), the industry leader in bioactive lipid-targeted therapeutics, received official notification from the U.S. Patent and Trademark Office that the company has been issued another key patent supporting its iSONEP™ program. The newly issued U.S. patent, No. 8,614,103, is entitled, "Compositions and Methods for Treating Ocular Conditions." It claims methods of using monoclonal antibodies (including iSONEP) that bind sphingosine-1-phosphate (S1P) in the treatment of a wide variety of ocular conditions, including wet age-related macular degeneration (AMD).

"This patent adds additional coverage in the U.S. for use of our anti-S1P antibodies in the treatment of a wide range of ocular disorders and complements another recently issued patent (US 8,444,970) and certain patent claims we have been granted in Europe (European patent No. 1 948 234) for wet AMD, cancer, and other conditions," said Roger Sabbadini, Lpath's vice president, founder, and an inventor of the issued patent. "These three patents together provide exclusivity in our pursuit of ocular disorders beyond wet AMD where we believe aberrant levels of S1P may be involved in pathogenesis of disease."

Lpath is conducting a Phase 2 clinical trial for iSONEP, the Nexus trial, which is evaluating the anti-S1P antibody's safety and efficacy in wet-AMD patients that have not responded well to existing anti-VEGF therapies including Lucentis®, Avastin® and Eylea®. Lpath entered into an agreement with Pfizer (NYSE: PFE) in 2010 that provides Pfizer an exclusive option for a worldwide license to develop and commercialize iSONEP.

Additionally, Lpath is independently conducting a Phase 2 trial in renal cell carcinoma patients with ASONEP™, an anti-S1P antibody that is formulated for systemic delivery.

Both iSONEP and ASONEP are first-in-class therapeutics developed using Lpath's ImmuneY2™ drug-discovery engine. Antibodies developed via this discovery engine are designed to target bioactive signaling lipids, such as S1P, that are involved in cancer, AMD, inflammatory and auto-immune disorders, and many other diseases.

About Lpath's Patent Portfolio
Lpath has achieved a broad and deep intellectual property position in the bioactive-lipid area and t its comprehensive patent portfolio now includes 29 issued patents and 27 patent applications in the U.S., with corresponding international patents and applications. These patents primarily relate to the use of reagents and methods designed to interfere with the actions of bioactive lipids involved in human disease. Lpath's intellectual property portfolio includes coverage of compositions of matter that specifically bind to sphingolipids and sphingolipid metabolites. These compositions, including antibodies, could be used in the diagnosis and treatment of various diseases and disorders, including cardiovascular and cerebrovascular disease, cancer, inflammation, autoimmune disorders, ocular disease, and angiogenesis.

Lpath has also obtained issued patent claims on sphingolipid targets (e.g., receptors and signaling sphingolipids) and methods for using such targets in drug-discovery screening efforts.

The company believes that its patent portfolio provides broad and commercially significant coverage of antibodies, receptors, enzymes, and other moieties that bind to a lysolipid (or a sphingolipid metabolite) for diagnostic, therapeutic, and screening purposes.
