Abstract
PURPOSE To achieve reductions in infusion time, infusion sites, and frequency, a prospective, open-label, multicenter, Phase 3 study evaluated the safety, efficacy, and tolerability of subcutaneous immunoglobulin (SCIG) 16.5% (Cutaquig®, Octapharma) at enhanced infusion regimens. METHODS Three separate cohorts received SCIG 16.5% evaluating volume, rate, and frequency: Cohort 1) volume assessment/site: up to a maximum 100 mL/site; Cohort 2) infusion flow rate/site: up to a maximum of 100 mL/hr/site or the maximum flow rate achievable by the tubing; Cohort 3) infusion frequency: every other week at twice the patient's weekly dose. RESULTS For Cohort 1 (n = 15), the maximum realized volume per site was 108 mL/site, exceeding the currently labeled (US) maximum (up to 40 mL/site for adults). In Cohort 2 (n = 15), the maximum realized infusion flow rate was 67.5 mL/hr/site which is also higher than the labeled (US) maximum (up to 52 mL/hr/site). In Cohort 3 (n = 34), the mean total trough levels for every other week dosing demonstrated equivalency to weekly dosing (p value = 0.0017). All regimens were well tolerated. There were no serious bacterial infections (SBIs). Most patients had mild (23.4%) or moderate (56.3%) adverse events. The majority of patients found the new infusion regimens to be better or somewhat better than their previous regimens and reported that switching to SCIG 16.5% was easy. CONCLUSIONS SCIG 16.5% (Cutaquig®), infusions are efficacious, safe, and well tolerated with reduced infusion time, fewer infusion sites, and reduced frequency. Further, the majority of patients found the new infusion regimens to be better or somewhat better than their previous regimens.

Safety and Tolerability of Manual Push Administration of Subcutaneous IgPro20 at High Infusion Rates in Patients with Primary Immunodeficiency: Findings from the Manual Push Administration Cohort of the HILO Study. J Clin Immunol 2020; 41:66-75. [PMID: 33025378 PMCID: PMC7846525 DOI: 10.1007/s10875-020-00876-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 09/25/2020] [Indexed: 01/29/2023]
Abstract
Purpose To evaluate the safety and tolerability of IgPro20 manual push (also known as rapid push) infusions at flow rates of 0.5–2.0 mL/min. Methods Patients with primary immunodeficiency (PID) with previous experience administering IgPro20 (Hizentra®, CSL Behring, King of Prussia, PA, USA) were enrolled in the Hizentra® Label Optimization (HILO) study (NCT03033745) and assigned to Pump-assisted Volume Cohort, Pump-assisted Flow Rate Cohort, or Manual Push Flow Rate Cohort; this report describes the latter. Patients administered IgPro20 via manual push at 0.5, 1.0, and 2.0 mL/min/site for 4 weeks each. Responder rates (percentage of patients who completed a predefined minimum number of infusions), safety outcomes, and serum immunoglobulin G (IgG) trough levels were evaluated. Results Sixteen patients were treated; 2 patients (12.5%) discontinued at the 1.0-mL/min level (unrelated to treatment). Responder rates were 100%, 100%, and 87.5% at 0.5-, 1.0-, and 2.0-mL/min flow rates, respectively. Mean weekly infusion duration decreased from 103–108 to 23–28 min at the 0.5- and 2.0-mL/min flow rates, respectively. Rates of treatment-related treatment-emergent adverse events (TEAEs) per infusion were 0.023, 0.082, and 0.025 for the 0.5-, 1.0-, and 2.0-mL/min flow rates, respectively. Most TEAEs were mild local reactions and tolerability (infusions without severe local reactions/total infusions) was 100% across flow rate levels. Serum IgG levels (mean [SD]) were similar at study start (9.36 [2.53] g/L) and end (9.58 [2.12] g/L). Conclusions Subcutaneous IgPro20 manual push infusions at flow rates up to 2.0 mL/min were well tolerated and reduced infusion time in treatment-experienced patients with PID.
