La Jolla Pharmaceutical Company Receives Notice of Allowance for Patent Covering Modified Pectin Compositions

SAN DIEGO, CA--(Marketwire - Feb 5, 2013) - La Jolla Pharmaceutical Company (OTCQB: LJPC) ("La Jolla" and "Company"), a leader in the development of therapeutics that target galectin-3, announced today that the United States Patent and Trademark Office (USPTO) has issued a notice of allowance for claims covering its lead product candidate, GCS-100, from patent application number 13/588,932. The claims, which expire in 2025 without accounting for any potential patent term extension, provide proprietary protection for solutions comprised of purified modified pectin, with a defined average molecular weight range.

"This patent complements our other issued patents and strengthens our position as the leader in the development of effective, pectin-based therapeutics," said James Rolke, Senior Director of Research and Development at La Jolla and inventor of the technology.

George Tidmarsh, M.D., Ph.D., President and Chief Executive Officer of La Jolla, stated, "The allowance of these claims represents another step in building our proprietary protection of GCS-100 and modified pectin compositions derived from any source. We are prosecuting additional patent claims that may provide further protection of our lead role targeting galectin-3 with pectin-derived products."

La Jolla Pharmaceutical Company is building a pipeline of drug candidates based on modified pectin, a polysaccharide chemically related to the natural pectin found in plant cell walls. Modified pectin has the ability to bind and sequester the protein galectin-3, over-expression of which has been implicated in a number of human diseases including chronic organ failure and cancer. The modified pectin compositions described in patent '932 may have the advantages of improved therapeutic potency, purity and composition uniformity. The claims allowed in this patent cover such pectin compositions regardless of the intended therapeutic use. 

The Company's intellectual property portfolio also includes two issued patents covering methods for preparing biologically active modified pectin, two pending patents describing modified pectin compositions, and one pending patent covering the method of reducing the rate of cancer growth by treating with a galectin inhibitor.
