Abstract
Objective: Access to crizanlizumab, a disease-modifying therapy for sickle cell disease (SCD), was provided through a managed access program (MAP, NCT03720626). The present analysis evaluated the impact of 12 months of crizanlizumab treatment on vaso-occlusive crises (VOCs), and on the use of opioids for VOC-related pain relief, in patients with SCD from the MAP.
Methods: From June 2018 to January 2023, 112 patients with a history of recurrent VOCs completed 12 months of crizanlizumab (5 mg/kg) treatment and were monitored for adverse events (AEs).
Results: Crizanlizumab led to reductions of 18.0% and 36.2% in the proportions of patients having ≥ 1 home- and ≥ 1 healthcare-managed VOCs. Median absolute changes (interquartile range) from baseline in the rates of home- and healthcare-managed VOCs were -3.0 (-6.0, -1.0) and -2.0 (-4.0, 0), respectively. Data stratified by genotype and prior hydroxyurea use showed similar reductions in VOC rates. A 35.5% reduction in the proportion of patients requiring opioids was noted. AEs were consistent with earlier reports, and no new safety concerns were identified.
Conclusions: Crizanlizumab demonstrated potential benefits in attenuating VOC episodes, irrespective of SCD genotype and prior hydroxyurea use, and in lowering opioid usage. The safety of crizanlizumab was consistent with earlier reports.
Trial registration: The MAP has been registered at ClinicalTrials.gov with the ID, NCT03720626.
期刊介绍:
European Journal of Haematology is an international journal for communication of basic and clinical research in haematology. The journal welcomes manuscripts on molecular, cellular and clinical research on diseases of the blood, vascular and lymphatic tissue, and on basic molecular and cellular research related to normal development and function of the blood, vascular and lymphatic tissue. The journal also welcomes reviews on clinical haematology and basic research, case reports, and clinical pictures.
