La Jolla Pharmaceutical Company Announces Notice of Allowance for U.S. Patent Covering LJPC-501
Patent Term Extends to 2034
SAN DIEGO–(BUSINESS WIRE)– La Jolla Pharmaceutical Company (Nasdaq: LJPC) (the Company or La Jolla), a leader in the development of innovative therapies intended to significantly improve outcomes in patients suffering from life-threatening diseases, today announced the issuance of a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for U.S. patent application number 14/575,127, entitled “Angiotensin II Alone or in Combination for the Treatment of Hypotension,” which covers LJPC-501, La Jolla’s proprietary formulation of angiotensin II for the potential treatment of catecholamine-resistant hypotension (CRH). LJPC-501 is currently the subject of a Phase 3 clinical trial for the treatment of CRH, and results from this trial are expected by the end of 2016.
La Jolla has an exclusive license to this patent application from the George Washington University, and the resulting patent will have a term extending to 2034. This Notice of Allowance concludes substantive examination of the patent application and will result in the issuance of a U.S. patent after administrative processes are completed. Additional claims are being pursued in a continuation application.
“This newly allowed patent covering LJPC-501 is a valuable addition to La Jolla’s intellectual property portfolio,” said George F. Tidmarsh, M.D., Ph.D., President and CEO of La Jolla. “We believe that LJPC-501 has the potential to reverse acute hypotension in critically ill patients and, therefore, provide a significant benefit to patients suffering from CRH.”
LJPC-501 is La Jolla’s proprietary formulation of angiotensin II. Angiotensin II, the major bioactive component of the renin-angiotensin system, serves as one of the body’s central regulators of blood pressure. La Jolla is developing LJPC-501 for the treatment of catecholamine-resistant hypotension (CRH), which is an acute, life-threatening condition in which blood pressure drops to dangerously low levels in patients who respond poorly to current treatments. Angiotensin II has been shown to raise blood pressure in a randomized, placebo-controlled clinical trial in CRH, which was recently published in the journal Critical Care, as well as in animal models of hypotension. Preclinical pharmacology studies that La Jolla has conducted have demonstrated that catecholamine resistance may be in part a result of reduced endogenous production of angiotensin II. In October 2014, La Jolla presented positive data from a preclinical study of LJPC-501 for the treatment of CRH.
La Jolla initiated a Phase 3 clinical trial with LJPC-501 for the treatment of CRH, called the ATHOS (Angiotensin II for the Treatment of High-Output Shock) 3 trial, in March 2015. In February 2015, La Jolla reached agreement with the U.S. Food and Drug Administration (FDA) on a Special Protocol Assessment (SPA) for this multicenter, randomized, double-blind, placebo-controlled, Phase 3 clinical trial. In accordance with the SPA, the primary efficacy endpoint for the ATHOS 3 registration trial is increase in blood pressure at three hours. The ATHOS 3 trial is designed to enroll approximately 315 patients. Patients are to be randomized in a 1:1 fashion to receive either: (i) LJPC-501 plus standard-of-care vasopressors; or (ii) placebo plus standard-of-care vasopressors. Randomized patients are to receive their assigned treatment via continuous IV infusion for up to seven days. The primary efficacy endpoint in the study is to compare the change in mean arterial pressure in patients with CRH who receive an IV infusion of LJPC-501 plus standard-of-care vasopressors to those that receive placebo plus standard-of-care vasopressors. Secondary endpoints include comparison of changes in Cardiovascular Sequential Organ Failure Assessment, or SOFA scores, and the safety and tolerability of LJPC-501 in patients with CRH. Results from ATHOS 3 are expected by the end of 2016.
