La Jolla Pharmaceutical Company Announces FDA Acceptance of IND for LJPC-401

SAN DIEGO--()--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 that the U.S. Food and Drug Administration (FDA) has accepted the Company’s Investigational New Drug Application (IND) for LJPC-401, La Jolla’s novel formulation of hepcidin. La Jolla expects to release preliminary results from a Phase 1 clinical trial of LJPC-401 by the end of 2015.

Hepcidin is a naturally occurring regulator of iron absorption and distribution. By regulating the absorption and distribution of iron, hepcidin prevents excessive iron accumulation in tissues, such as the liver and heart, where it can cause significant damage and even result in death.

La Jolla is developing LJPC-401 for the treatment of iron overload, which occurs as a result of diseases such as hereditary hemochromatosis (HH) and beta thalassemia. HH is a disease caused by a genetic deficiency in hepcidin that results in excessive iron accumulation. HH is the most common genetic disease in Caucasians and causes liver cirrhosis, liver cancer, heart disease and/or failure, dementia and diabetes.

LJPC-401 has been shown to be effective in reducing serum iron in preclinical testing. Specifically, La Jolla has completed animal toxicology studies that demonstrated a dose-dependent reduction in serum iron levels in all species tested.

“We are pleased to have received clearance from the FDA to begin a Phase 1 study of LJPC-401,” said George F. Tidmarsh, M.D., Ph.D., President and Chief Executive Officer of La Jolla. “LJPC-401 presents a unique opportunity to potentially help patients suffering from the effects of iron overload by restoring normal or near-normal levels of hepcidin, the body’s natural regulator of iron absorption and distribution.”
