Tolerability of subcutaneous immunoglobulin 20%, Ig20Gly, in pediatric patients with primary immunodeficiencies

Aim: To assess Ig20Gly tolerability in pediatric patients with primary immunodeficiencies. Patients & methods: Infusion parameters and tolerability were analyzed in pediatric patients (aged 2-5 years [n=6], 6-11 years [n=22] and 12-17 years [n=22]) receiving Ig20Gly in two Phase II/III trials. Results: Of 2624 Ig20Gly infusions, >99% did not require any rate reduction, interruption or discontinuation due to adverse events (AEs). Median maximum infusion rates and volumes/site were higher in patients 12-17 years of age (30ml/h/site; 30ml/site) versus 6-11 years (20ml/h/site; 15ml/site) and 2-5 years (18ml/h/site; 14ml/site). Rates of causally related systemic and local AEs (0.009 and 0.063 AEs/infusion) were low. Conclusion: Ig20Gly infused at relatively high rates and volumes was well tolerated in children

Home-based subcutaneous immunoglobulin G replacement therapy under real-life conditions in children and adults with antibody deficiency

Background: Subcutaneous immunoglobulin (SCIG) therapy is an alternative to intravenous immunoglobulin (WIG) therapy.Methods: We evaluated the efficacy and safety of the SCIG Vivaglobin (R) (formerly known as Beriglobin (R) SC) under real-life conditions in a post-marketing observational study in 82 patients with primary or secondary antibody deficiencies. Health-related quality of life (HRQoL) was evaluated in a subset of 30 patients previously treated with WIG (including 11 children <14 years) using the Short Form 36 (SF-36) for patients >= 14 years of age (adults) and the Child Health Questionnaire - Parental Form 50 (CHQ-PF50) for children <14 years of age. Treatment preferences were assessed in adults.Results: The mean serum immunoglobulin G (IgG) trough level during SCIG treatment (7.5 g/L) was higher than during previous IVIG treatment (6.6 g/L; p<0.01). The investigators assessed the efficacy of SCIG therapy as "excellent" in 89% of patients. No systemic adverse drug reactions were observed. Improvements by >= 5 points were observed in 5 of 8 SF-36 subscales and in 6 of 12 CHQ-PF50 subscales. Statistically significant improvements (p <= 0.05) were observed for the SF-36 subscales of bodily pain, general health perceptions, and vitality (adults), and for the CHQ-PF50 subscales of general health perceptions, parental impact - time, parental impact - emotional, and family activities (children). Patients preferred SCIG over WIG therapy (92%) and home therapy over therapy at the clinic/physician (83%).Conclusion: This study confirms that therapy with Vivaglobin (R) at home is effective, safe, well tolerated, and improves quality of life in patients with antibody deficiency

Efficacy and Safety of a New 20% Immunoglobulin Preparation for Subcutaneous Administration, IgPro20, in Patients With Primary Immunodeficiency

Subcutaneous human IgG (SCIG) therapy in primary immunodeficiency (PID) offers sustained IgG levels throughout the dosing cycle and fewer adverse events (AEs) compared to intravenous immunoglobulin (IVIG). A phase I study showed good local tolerability of IgPro20, a new 20% liquid SCIG stabilized with L-proline. A prospective, open-label, multicenter, single-arm, phase III study evaluated the efficacy and safety of IgPro20 in patients with PID over 15 months. Forty-nine patients (5–72 years) previously treated with IVIG received weekly subcutaneous infusions of IgPro20. The mean serum IgG level was 12.5 g/L. No serious bacterial infections were reported. There were 96 nonserious infections (rate 2.76/patient per year). The rate of days missed from work/school was 2.06/patient per year, and the rate of hospitalization was 0.2/patient per year. Ninety-nine percent of AEs were mild or moderate. No serious, IgPro20-related AEs were reported. IgPro20 effectively protected patients with PID against infections and maintained serum IgG levels without causing unexpected AEs

Efficacy and Safety of Hizentra®, a New 20% Immunoglobulin Preparation for Subcutaneous Administration, in Pediatric Patients with Primary Immunodeficiency

Subcutaneous IgG treatment for primary immunodeficiencies (PI) is particularly well suited for children because it does not require venous access and is mostly free of systemic adverse events (AEs). In a prospective, open-label, multicenter, single-arm, Phase III study, 18 children and five adolescents with PI were switched from previous intravenous (IVIG) or subcutaneous (SCIG) IgG treatment to receive dose-equivalent, weekly subcutaneous infusions of Hizentra® for 40 weeks. Mean IgG trough levels were maintained in patients previously on SCIG, or increased in those previously on IVIG, regardless of age. No serious bacterial infections were reported during the efficacy period of the study. The rates of non-serious infections were 4.77 (children) and 5.18 (adolescents) infections per patient per year. Related AEs were observed in seven children (38.9%) and two adolescents (40%). Three serious AEs and two AEs leading to discontinuation (all unrelated) were reported in children. Hizentra® is an effective and well-tolerated treatment for pediatric patients

Probing the Links between Political Economy and Non-Traditional Security: Themes, Approaches, and Instruments

This is a pre-print of an article published in International Politics. The definitive publisher-authenticated version of: Hameiri, Shahar, and Lee Jones. "Probing the links between political economy and non-traditional security: Themes, approaches and instruments." International Politics (2015), is available online at: http://dx.doi.org/10.1057/ip.2015.1In recent decades, the security agenda for states and international organisations has expanded dramatically to include a range of ‘non-traditional’, transnational security issues. It is often suggested that globalisation has been a key driver for the emergence or intensification of these problems, but, surprisingly, little sustained scholarly effort has been made to examine the link between responses to the new security agenda and the changing political economy. This curious neglect largely reflects the mutual blind-spots of the sub-disciplines of International Security Studies and International Political Economy, coupled with the dominance of approaches that tend to neglect economic factors. This special issue, which this article introduces, aims to overcome this significant gap. In particular, it focuses on three key themes: the broad relationship between security and the political economy; what is being secured in the name of security, and how this has changed; and how things are being secured – what modes of governance have emerged to manage security problems. In all of these areas, the contributions point to the crucial role of the state in translating shifting state-economy relations to new security definitions and practices
