Summary

This study looks at the long-term safety and effectiveness of an injection called LP-005 in adults with paroxysmal nocturnal hemoglobinuria (PNH), a rare blood disorder. It is for people who already completed an earlier LP-005 study. The goal is to see if LP-005 can help control the disease over time by checking side effects, blood levels, and the need for blood transfusions.
