Brief Summary:
The purpose of this study is to evaluate crovalimab for the treatment of a sickle cell pain crisis (also known as a VOE) that requires hospitalisation in adult and adolescent participants with SCD. The primary objective of this study is safety and will additionally evaluate pharmacokinetics (how crovalimab is processed by your body), pharmacodynamics (how your body reacts to crovalimab) and the preliminary efficacy of crovalimab compared with placebo.

Condition or disease Intervention/treatment Phase

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 30 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase IB Randomized, Placebo-Controlled Study Evaluating the Safety, Pharmacokinetics, Pharmacodynamics, and Efficacy of Crovalimab for the Management of Acute Uncomplicated Vaso-Occlusive Episodes (VOE) in Patients With Sickle Cell Disease (SCD)
Actual Study Start Date : March 26, 2022
Estimated Primary Completion Date : January 14, 2025
Estimated Study Completion Date : July 14, 2025

Arm Intervention/treatment
Experimental: Crovalimab
Participants will receive a single intravenous (IV) infusion of Crovalimab based on body weight.
Drug: Crovalimab
Crovalimab will be administered as a single dose of 1000 milligrams (mg) IV (for participants with a body weight between 40 kilograms (kg) and 100 kg) or 1500 mg IV (for participants with a body weight >=100 kg).

Placebo Comparator: Placebo
Participants will receive a single IV infusion of matching Placebo.
Drug: Placebo
Placebo will be administered as a single IV infusion, with an equal volume and over the same duration as weight- based crovalimab

Primary Outcome Measures :

  4. Time to readiness for hospital discharge from baseline [ Time Frame: Baseline up to Day 84 ]
  5. Time to hospital discharge from baseline [ Time Frame: Baseline up to Day 84 ]
  6. Time to a confirmed decrease in pain score of at least 2 points from the maximal pre-dose pain score [ Time Frame: Baseline up to Day 84 ]
  7. Change in pain score from the maximal pre-dose pain score to the score at hospital discharge [ Time Frame: Baseline up to Day 84 ]
  8. Percentage of Participants who develop Acute Chest Syndrome (ACS) [ Time Frame: Baseline up to Day 28 ]
  9. Percentage of Participants requiring intensive care unit (ICU)/critical care admission for SCD-related complications [ Time Frame: Baseline up to Day 84 ]
  10. Percentage of Participants requiring blood transfusion for SCD-related complications [ Time Frame: Baseline up to Day 84 ]
  11. Readmission rate for a VOE or VOE-related event within 28 days of discharge of the primary VOE [ Time Frame: Baseline up to Day 84 ]
  12. Serum Concentrations of Crovalimab over time [ Time Frame: Baseline up to Day 84 ]
  13. Change in PD biomarkers including complement activity (CH50) over time [ Time Frame: Baseline up to Day 84 ]
    Assessed by a Liposome Immunoassay (LIA)

  14. Change over time in free C5 concentration [ Time Frame: Baseline up to Day 84 ]
  15. Change over time in soluble complement 5b 9 (sC5b-9) concentration [ Time Frame: Baseline up to Day 84 ]
