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

Description

This study consists of two parts: phase 2 (Part A) and phase 3 (Part B). It is a multicenter study designed to evaluate the safety, effectiveness, 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 assess how CSL889 affects the time it takes for VOC to resolve in participants with SCD, and to evaluate the safety and tolerability of CSL889 in study participants.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Diagnosed with SCD (any genotype).
  • * Presented at the study site with a new acute VOC necessitating treatment with parenteral opioids.
  • * VOC pain onset greater than or equal to (\>=) 72 hours before administration of first parenteral opioid (Part A; may be adjusted for Part B based on prespecified analysis).
  • * Must not have a history of greater than (\>) 5 VOCs requiring hospital admission in the past 6 months; or signs and / or symptoms of ACS; or new neurological symptoms suggestive of acute stroke or transient ischemic attack; or any stage (acute kidney injury) AKI; or been discharged from inpatient hospital admission for VOC or other vaso-occlusive event within 14 days before the current presentation.
  • * Serum hemoglobin \< 6 g/dL, serum ferritin \>= 2000 ng/mL, receiving an approved medication for SCD that has not been on a stable, well-tolerated regimen, currently taking methadone or buprenorphine.
