Purpose

The goal of the study is to evaluate descriptively the effect of crizanlizumab + standard of care and standard of care alone on renal function in sickle cell disease patients ≥ 16 years with chronic kidney disease due to sickle cell nephropathy.

Inclusion Criteria

  • Confirmed diagnosis of SCD (HbSS and HbSβ0-thal SCD genotypes are eligible) - Patients with eGFR ≥ 45 to ≤ 140 mL/min/1.73 m2 based on CKD EPI formula (patients ≥ 18) or the Creatinine-based "Bedside Schwartz" equation (patients < 18) - Patients with ACR of ≥ 100 to < 2000 mg/g (taken as an average of the three screening ACR values to determine eligibility) - Receiving at least 1 standard of care drug(s) for SCD-related CKD: If receiving HU/HC, the patient must have been receiving HU/HC for at least 6 months and on a stable dose for 3 months, and/or an ACE inhibitor and/or ARB for 3 months and on a stable dose for those 3 months. - Hb ≥ 4.0 g/dL, absolute neutrophil count (ANC) ≥ 1.0 x 10^9/L, and platelet count ≥ 75 x 10^9/L - Adequate hepatic function as defined by: - Alanine aminotransferase (ALT) < 3.0 x upper limit of normal (ULN) - Direct (conjugated) bilirubin ≤ 3.0 x ULN - Written informed consent (or assent/ parental consent for minor subjects) prior to any screening procedures

Exclusion Criteria

  • History of stem cell transplant - Patients with evidence of AKI within 3 months of study entry (can decrease interval to within 6 weeks of study entry only if renal function has returned to pre-AKI values prior to study entry) - Blood pressure > 140/90 mmHg despite treatment - Patients undergoing renal replacement therapy (ie. hemodialysis, peritoneal dialysis, hemofiltration and kidney transplantation) - Received blood products within 30 days of Week 1 Day 1 - Participating in a chronic transfusion program - History of kidney transplant - Patients with hypoalbuminemia - Body mass index of ≥ 35 - Currently receiving or received voxelotor within 6 months of screening - Patient has received crizanlizumab and/or other selectin inhibitor or plans to receive it during the duration of the study. Other protocol-defined inclusion/exclusion criteria may apply
