Detailed Description

Study CSEG101A2202 was designed as a Phase II, multicenter, open-label study. The first 45 patients (to identify 27 evaluable patients) were enrolled to the treatment group crizanlizumab 5.0 mg/kg to complete full PK/PD sampling at week 1 and week 15. In all patients, trough PK/PD samples was collected prior to each dose. In addition, throughout the study (and when possible), all patients had blood drawn for serum to assess PK and PD drawn at times of onset and resolution of each VOC event, fever, or infection. Once the up to 45 patients were enrolled, 12 additional patients were enrolled to the exploratory treatment group and begin at 7.5 mg/kg of crizanlizumab.
