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 reported financial results for the three and nine months ended September 30, 2016 and recent corporate progress. Recent Corporate Progress In September 2016, La Jolla reported positive results from a multicenter, open-label, dose-escalation Phase 1 trial of LJPC-401, the Company's novel formulation of synthetic human hepcidin, in patients at risk for iron overload due to conditions such as hereditary hemochromatosis (HH), beta thalassemia, sickle cell disease (SCD) and myelodysplastic syndrome (MDS). Fifteen patients were dosed at escalating dose levels ranging from 1 to 20 mg. LJPC-401 was well tolerated, and there were no dose-limiting toxicities observed. A dose-dependent, statistically significant reduction in serum iron was observed (p=0.008 for dose response; not adjusted for multiple comparisons). At the 20 mg dose level, LJPC-401 reduced serum iron by an average of 58.1% from baseline to hour 8 (p=0.001; not adjusted for potential regression to the mean effect), and serum iron had not returned to baseline through day 7 (21.2% reduction from baseline to the end of day 7). In September 2016, La Jolla reached agreement with the European Medicines Agency (EMA) on the design of a pivotal trial of LJPC-401, the Company's novel formulation of synthetic human hepcidin. The pivotal trial will be a randomized, controlled, multicenter trial in beta thalassemia patients suffering from iron overload, a major unmet need in an orphan patient population. The primary endpoint will be a clinically relevant measurement directly related to iron overload. La Jolla plans to initiate this pivotal trial in mid-2017. In October 2016, the EMA Committee for Orphan Medicinal Products (COMP) issued a positive opinion recommending LJPC-401, synthetic human hepcidin, for designation as an orphan medicinal product for the treatment of SCD.
