Crizanlizumab, sold under the brand name Adakveo among others, is a medication used to treat sickle cell disease.[2] Specifically it is used to reduce the frequency of vaso-occlusive crisis in people over 15 years old.[2] It is given by injection into vein.[2]

Common side effects include joint pain, nausea, fever, and abdominal pain.[1] Other side effects may include infusion reactions.[2] Use in pregnancy may harm the baby.[2] It is a monoclonal antibody that binds to and blocks P-selectin, decreasing the attaching of cells to the inside of blood vessels.[1]

Crizanlizumab was approved for medical use in the United States in 2019 and Europe in 2020.[2][1] In the United Kingdom 100 mg costs the NHS about £1,000 as of 2021.[5] This amount in the United States is about 2,400 USD.[6]

Medical use


It is given at a dose of 5 mg/kg at 0 and 2 weeks, followed by every 4 weeks.[2]


P-selectin molecules are present on the surface of activated platelets and vascular endothelial cells and have been linked to sickle cell vaso-occlusive crises.[7][8][9]


The U.S. Food and Drug Administration (FDA) approved crizanlizumab based on evidence from one clinical trial (Trial 1/NCT01895361) of 132 patients with sickle cell diseases who had a history of vaso-occlusive crisis.[10] The trial was conducted at 60 sites in the United States, Brazil and Jamaica.[10]

The FDA granted the application for crizanlizumab-tmca priority review, breakthrough therapy designation, and orphan drug designation.[11] The FDA granted approval of Adakveo to Novartis.[11][10]

The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.[12]
