Sickle cell disease (SCD) is a genetic blood disorder. Crizanlizumab has been approved in India and other countries to reduce the frequency of vaso-occlusive crises (VOCs) in patients with SCD aged 16 years and older.
The purpose of this local Phase IV study is to evaluate the safety of crizanlizumab specifically in Indian patients with SCD aged 16 years or older with a history of VOC leading to healthcare visit.

16 Years and older (Child, Adult, Older Adult)
Crizanlizumab will be taken by IV infusion, at Week 1 Day 1, Week 3 Day 1 and all 4 weeks thereafter.
Signed informed consent
Male or female participant aged 16 years and older
Confirmed diagnosis of SCD by hemoglobin electrophoresis or high performance liquid chromatography (HPLC). All SCD genotypes are eligible.
History of VOC leading to healthcare visit prior to screening visit
Participants must meet the following central laboratory values at the screening visit:
Absolute Neutrophil Count ≥1.0 x 109/L Platelet count ≥75 x 109/L Hemoglobin: for adults (Hb) ≥4.0 g/dL and for adolescents (Hb) ≥5.5 g/dL Glomerular filtration rate ≥ 45 mL/min/1.73 m2 using CKD-EPI formula Direct (conjugated) bilirubin < 2.0 x ULN Alanine Aminotransferase (ALT) < 3.0 x ULN
ECOG performance status ≤2 for adults and Karnofsky Performance Scale ≥ 50% for adolescents.
Contraindication or hypersensitivity to any drug or metabolites from similar class as study drug. History of severe hypersensitivity reaction to other monoclonal antibodies which in the opinion of the investigator may pose an increased risk of serious infusion reaction.
Participant has received crizanlizumab and/or other P-selectin inhibitor prior to the study or plans to receive it during the duration of the study.
Concurrent severe and/or uncontrolled medical conditions which, in the opinion of the Investigator, could cause unacceptable safety risks or compromise participation in the study.
Any condition which, in the opinion of the investigator, is likely to interfere with the successful collection of the measurements required for the study.
Participant has documented immunogenicity to a prior biological drug.
Participants who are on active treatment with Voxelotor, other investigational drug or other monoclonal antibody, or intend to initiate the same during the course of the trial.
