Conditions

Paroxysmal Nocturnal Hemoglobinuria (PNH)

Brief summary

Safety and tolerability as assessed by adverse events (AEs), vital signs, electrocardiograms (ECGs), and clinical laboratory tests.

Detailed description

Efficacy as measured by: proportion of patients achieving Hb ≥ 12.0 g/dL assessed at 6-month intervals; proportion of patients maintaining an increase in Hb ≥ 2 g/dL, achieved in the prior study; proportion of patients who are transfusion free at Weeks 48 and 96; proportion of patients experiencing clinical BTH at Weeks 48 and 96; mean LDH and absolute reticulocyte changes from from baseline, start of the long-term extension, at Weeks 48 and 96; zaltenibart PK concentrations and PD parameters
