Trial Outcomes & Findings for Efficacy, Pharmacokinetics, Safety, and Tolerability of IGSC 20% in Subjects With Primary Immunodeficiency (NCT NCT02806986)

NCT ID: NCT02806986

Last Updated: 2020-06-16

Results Overview

The rate of SBI events per participant per year during IGSC 20% treatment was calculated as the total number of SBI events divided by the total duration of exposure in years across all participants. The 2-sided 98% confidence interval (CI) was determined from a generalized linear model for poisson regression for the log-transformed number of events with log-transformed duration of exposure in years as an offset variable.

Participant Flow

Participants with primary immunodeficiency (PI) requiring IgG replacement were enrolled. Study has 3 stages: Screening/Previous Regimen Phase, Treatment Stage 1 and 2. Total 62 participants entered Previous Regimen Phase, of which 61 entered in Treatment Stage 1 to receive IGSC 20%. Study was conducted in 8 countries from June 2016 to May 2019.

Participants had no SBI within last 3 months prior to screening and were on immunoglobulin G (IgG) replacement therapy (stable regimen via intravenous \[IV\] or subcutaneous \[SC\] infusion) for ≥3 consecutive months prior to screening. Participants receiving IVIG prior to study entry must have received a dosage of ≥200 mg/kg per infusion.

IGSC 20%
Following the previous regimen phase (screening), participants were enrolled to receive 13 immune globulin subcutaneous (human), 20% caprylate/chromatography purified (IGSC 20%) infusions at weekly intervals from baseline (Week 1) up to Week 13 in treatment stage 1. Participants were infused with IGSC 20% at a 1:1 dose-equivalent regimen from their previous regimen (or a minimum IGSC 20% dose of 100 milligram per kilogram per week (mg/kg/week) if the derived 1:1 dose from the previous regimen was lower) and followed by 39 IGSC 20% infusions at weekly intervals from Week 14 up to Week 52 in treatment stage 2. Dose adjustments were permitted per the study protocol and at the Investigator's discretion in the treatment stage 1. However, dose remained constant in treatment stage 2 unless it was absolutely medically necessary to change the dose, and such change required prior consultation with the Sponsor's Medical Monitor. A final follow-up visit occurred at Week 53.

PRIMARY outcome

Timeframe: IGSC 20% Treatment Stage 1: Week 1 to 13; IGSC 20% Treatment Stage 2: Week 14 to 53; IGSC 20% Overall: Week 1 to 53

Population: Analysis was performed on the efficacy evaluable population which included all participants who received at least 1 dose of IGSC 20%.

The rate of SBI events per participant per year during IGSC 20% treatment was calculated as the total number of SBI events divided by the total duration of exposure in years across all participants. The 2-sided 98% confidence interval (CI) was determined from a generalized linear model for poisson regression for the log-transformed number of events with log-transformed duration of exposure in years as an offset variable.

SECONDARY outcome

Timeframe: Previous Regimen Phase: 2 timepoints pre-dose of pIV or pSC between Screening and Baseline (up to 8 weeks). IGSC 20% Phase: Pre-dose of IGSC 20% at Baseline (Week 1), Weeks 2, 5, 9, 13, 17, 18, 20, 24, 28, 32, 36, 40, 44, 48, 52, and at Week 53

Population: Analysis was performed on the IgG population which consisted of all participants who received any amount of IGSC 20% and had total IgG concentration data to facilitate the comparison of mean trough IgG concentration during the IGSC 20% phase versus the pre-treatment phase.

Mean trough total IgG concentration during the previous regimen phase was calculated as the average of the trough concentrations at the previous IVIG (pIV)#1 and pIV#2 visits for participants entering the study on a previous IVIG regimen, or at the previous subcutaneous immune globulin (SCIG) (pSC)#1 and baseline/SC#1 visits for participants entering the study on a previous SCIG regimen. Mean trough total IgG concentration during the IGSC 20% phase was calculated as the average of all steady state trough concentrations measured during the IGSC 20% treatment stage 2 at the visits corresponding to Weeks 17, 18, 20, 24, 28, 32, 36, 40, 44, 48, 52 and 53.

Population: Analysis was performed on the efficacy evaluable population which included all participants who received at least 1 dose of IGSC 20%.

The total number of infections of any kind (serious/non-serious including acute sinusitis, exacerbation of chronic sinusitis, acute otitis media, pneumonia, acute bronchitis, infectious diarrhea, etc.) as determined by the investigator were evaluated. The rate of infection events per participant per year during IGSC 20% treatment was calculated as the total number of infection events divided by the total duration of exposure in years across all participants. The 2-sided 95% CI was determined from a generalized linear model for poisson regression for the log-transformed number of events with log-transformed duration of exposure in years as an offset variable.
