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 reported positive results from its Phase 1 study of LJPC-401 in patients at risk of iron overload.
The Phase 1 study is a multi-center, open-label, dose-escalation study evaluating the safety, tolerability, and effect on serum iron of a single dose of LJPC-401 in patients at risk of iron overload due to conditions such as hereditary hemochromatosis (HH), thalassemia, and sickle cell disease (SCD). Fifteen patients were dosed at escalating dose levels ranging from 1 mg to 20 mg.
LJPC-401 was well tolerated, and there were no dose-limiting toxicities observed. Injection-site reactions were the most commonly reported adverse event. These were all mild or moderate in severity, self-limiting, and fully resolved. There were no significant changes in serum chemistries or hematology other than serum iron parameters.
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).
