Efficacy and safety of octanorm (cutaquig) in adults with primary immunodeficiencies with predominant antibody deficiency: a prospective, open-label study.

To evaluate efficacy and safety of octanorm (16.5% subcutaneous immunoglobulin) in adult patients with primary immunodeficiencies. Primary immunodeficiencies patients (18-70 years) previously treated with intravenous immunoglobulin were included in this Phase III study. Octanorm was administered subcutaneously once weekly over 8 months. End points included infections, adverse events and quality of life. 25 patients (mean age 35.2 years, female 60.0%) were recruited, 24 completed the study. Mean dose of octanorm was 0.11 g/kg/week. No serious bacterial infections occurred. Three patients (12.0%) had an adverse event (mild) assessed as related to octanorm. Both the mental and physical summary 36-item Short Form Health Survey scores were improved. Octanorm is effective, safe and improves quality of life. NCT03988426.
