Abstract
Purpose: The FIGARO study aims to provide insights on real-world utilization and tolerability of facilitated subcutaneous immunoglobulin (fSCIG) for primary immunodeficiency disease (PID) or secondary immunodeficiency disease (SID). Methods: This prospective, multicenter, observational study, evaluated medical records, charts, and diaries of patients who had received at least 1 fSCIG infusion for PID or SID. Data were analyzed by cohort (PID, SID) and age groups (pediatric [< 18 years], adult [18–64 years], older adult [≥ 65 years]). Patients were followed up to 36 months. Results: The study enrolled 156 patients: 15 pediatric, 120 adult, 21 older-adult. Twelve-month follow-up data were available for 128 patients. fSCIG was mainly prescribed for PID among patients aged < 65 years and for SID among older adults. At inclusion, 75.6% received their fSCIG infusion at home, and 78.7% self-administered. Adults were more likely to receive their initial infusion at home and self-administer (81.7% and 86.6%, respectively) than pediatric patients (53.3% each) and older adults (57.1% and 52.4%, respectively). At 12 months, the proportion of patients infusing at home and self-administering increased to 85.8% and 88.2%. Regardless of age, most patients self-administered the full fSCIG dose at home every 3–4 weeks and required a single infusion site. The tolerability profile was consistent with previous pivotal trials. Acute severe bacterial infections occurred in 0%–9.1% of patients during follow-up visits (full cohort). Conclusions: FIGARO confirms the feasibility, tolerability, and good infection control of fSCIG in PID and SID patients across the age spectrum in both the home-setting and medical facility.
