Recruiting Phase 2

Safety, Efficacy, and Pharmacokinetics of CSL889 in Adults and Adolescents With Sickle Cell Disease During Vaso-Occlusive Crisis

About this study

This is a phase 2, randomized, multiple-dose, placebo-controlled study designed to evaluate the safety, efficacy, and pharmacokinetics (PK) of CSL889 (human hemopexin) when given intravenously (IV) to adults and adolescents with sickle cell disease (SCD) experiencing vaso-occlusive crises (VOC). The main objectives of the study are to evaluate the safety and tolerability of CSL889 in study participants, and to assess how CSL889 affects the time it takes for VOC to resolve in participants with SCD.
