The purpose of this Cohort Treatment Plan is to allow access to crizanlizumab (SEG101) for eligible patients diagnosed with sickle cell disease (SCD) to prevent or reduce the frequency of vaso-occlusive crises (VOC). The patient's Treating Physician should follow the suggested treatment guidelines and comply with all local health authority regulations.

- History of reoccurring VOC as assessed by the Treating Physician.
- Patients receiving HU/HC, L-glutamine (Endari), erythropoietin stimulating agents or other therapies as prevention therapy and continue to experience VOC while on any of these treatments.
- Patients can continue taking the preventive therapy.
- Patient is not a candidate to be treated with alternative treatment options or has discontinued alternative treatments due to unacceptable benefit risk as documented by the Treating Physician.
- Patient must meet the following laboratory values prior to treatment:
- Absolute Neutrophil Count ≥1.0 x 109/L
- Platelets ≥75 x 109/L
- Hemoglobin (Hgb) ≥4.0 g/dL
- Estimated glomerular filtration rate ≥ 45 mL/min
- Direct (conjugated) bilirubin ≤2.0 x ULN
- Alanine transaminase (ALT) ≤ 3.0 x ULN
- ECOG performance status ≤ 2
