Crizanlizumab for the Prevention of Vaso-Occlusive Pain Crises in Sickle Cell Disease.

Abstract

Objective: To review the efficacy and safety of crizanlizumab (Adakveo) in the prevention of vaso-occlusive pain crises in sickle cell disease. Data Sources: An English-language literature search of PubMed, MEDLINE, and Ovid (1946 to January 2021) was completed using the terms crizanlizumab, SEG101, SelG1, and sickle cell disease. Manufacturer prescribing information, article bibliographies, and data from clinicaltrials.gov were incorporated in the reviewed data. Study Selection/Data Extraction: All studies registered on clinicaltrials.gov were incorporated in the reviewed data. Data Synthesis: Crizanlizumab is the first monoclonal antibody approved for sickle cell disease to reduce the frequency of vaso-occlusive crises. One phase 2 clinical trial and a post hoc analysis of the trial have been published. Relevance to Patient Care and Clinical Practice: Crizanlizumab is a monthly intravenous infusion approved by the Food and Drug Administration for patients with sickle cell disease 16 years of age and older to reduce the frequency of vaso-occlusive crises. Conclusion: Crizanlizumab appears to be an efficacious therapy for patients with sickle cell disease to reduce the frequency of vaso-occlusive crises. Concerns include drug cost and administration. Long-term benefits and risks have not been determined.
