Health-related Quality of Life (HRQoL): Pediatric Quality of Life Inventory (PedsQL)
The Peds-QL is a generic Health-Related Quality of Life (HR QoL) instrument designed specifically for a pediatric population. It captures the following domains: general health/activities, feelings/emotional, social functioning, school functioning. In this study, 2-7 years (parent as observer), 8-13 years (participant as observer) for Peds-QL health questionnaire will be analyzed. Higher scores indicate better quality of life (QOL) for all domains of the Peds-QL. This modular instrument uses a 5-point scale: from 0 (never) to 4 (almost always). Items are reversed scored and linearly transformed to a 0-100 scale as follows: 0=100, 1=75, 2=50, 3=25, 4=0. Four dimensions (physical, emotional, social, & school functioning) are scored.
EuroQoL (Quality of Life)-5 Dimensions 3 Levels (EQ-5D-3L)
EQ-5D-3L health questionnaire is a participant answered questionnaire scoring 5 dimensions - mobility, self-care, usual activities, pain/discomfort and anxiety/depression. In this study, 2-11 years (parent as observer),12 years and older (participant as observer) for EQ-5D-3L health questionnaire will be analyzed. The EQ-5D-3L total score ranges from 0 (worst health state) to 1 (perfect health state) and 1 reflects the best outcome.
Health-related Quality of Life (HRQoL): Short Form-36 Health Survey (SF-36)
The SF-36 is a generic quality-of-life instrument that has been widely used to assess health-related quality of life (HRQL) of participants. In this study, 14 years and older (participant as observer) for SF-36 health questionnaire will be analyzed. Generic instruments are used in general populations to assess a wide range of domains applicable to a variety of health states, conditions, and diseases. The SF-36 consists of 36 items that are aggregated into 8 multi-item scales (physical functioning, role - physical, bodily pain, general health, vitality, social functioning, role - emotional, and mental health), with scores ranging from 0 to 100. Higher scores indicate better HRQL.
Health Related Quality of Life: Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9)
Treatment Satisfaction Questionnaire for Medication (TSQM) is a global satisfaction scale used to assess the overall level of participant's satisfaction or dissatisfaction with their medications. In this study, 2-12 years (parent as observer), 13 years and older (participant as observer) for TSQM health questionnaire will be analyzed. TSQM-9 is a 9-item, validated, self-administered instrument used to assess participant's satisfaction with medication. The three domains assessed are effectiveness, convenience, and global satisfaction. The score of each of the 3 domains is based on an algorithm to create a score of 0 to 100. Higher score indicated greater satisfaction in that domain.
Health Related Quality of Life: Treatment Satisfaction Questionnaire for Life Quality Index (LQI)
The LQI is a self-administered questionnaire developed specifically for participants/legal guardians involved in IGIV treatments. In this study, 2-13 years (parent as observer), 14 years and older (participant as observer) for LQI health questionnaire will be analyzed. LQI consists of 15-items, divided into four domains: treatment interferences (6 items), therapy-related problems (4 items), therapy setting (3 items), and treatment costs (2 items). Items are rated on a 7-point Likert-type scale ranging from 1: "Extremely bad" to 7: "Extremely good". Total scores range from 15 to 105, with higher scores indicating the highest possible satisfaction with factors such as independence, therapy convenience, social/school/work activities, and health and travel costs.
Health Related Quality of Life: Treatment Preference
Treatment preference questionnaire is a self-administered questionnaire developed to assess participants' preference towards the administration of new IGSC therapy. There are 4-items on the questionnaire, which investigate a participant's preference on the clinic/hospital/home setting of receiving the immunoglobulin therapy, the participant's rating on the frequency and method of administration, and the participant's preference to continue receiving the IGSC treatment.

5. Study Description

Brief Summary
In this study, Japanese participants with primary immunodeficiency diseases were treated with Immune Globulin Subcutaneous (Human), 20% solution, (IGSC, 20%). This study will be in 3 parts: Part 1: Infusions with Immunoglobulin Intravenous (IGIV) every 3 weeks for 13 weeks. Part 2: Participants will switch to weekly subcutaneous infusions with IGSC, 20% for 24 weeks. Part 3: A subset will receive biweekly subcutaneous infusions with IGSC, 20% for 12 weeks. The main aim of the study is to assess base levels of Immunoglobulin globulin G (IgG) levels in the blood of the participants after weekly and biweekly treatment with IGSC, 20% (in Parts 2 and 3 of the study). Their PID will be treated by their doctor according to their doctor's usual clinical practice.
Detailed Description
This study consists of 3 treatment parts (Epoch 1, 2, 3). The total evaluation period of the study will be 57 weeks in which screening period is for 2-8 weeks and Epoch 1 is from Week 8 to Week 21, Epoch 2 is from Week 21 to Week 45, Epoch 3 is from Week 45 to Week 57. Each participant will receive IGIV treatment in Epoch 1 for a total of 13 weeks, then switch to weekly subcutaneous (SC) treatment with IGSC, 20% in Epoch 2 for a total of 24 weeks and will continue into Epoch 3 for a total of 12 weeks of biweekly SC treatment with IGSC, 20%. Drug dose in Epoch 2 and Epoch 3 will be adjusted so that it will be an equivalent weekly dose of the dose administered in Epoch 1 and twice the dose administrated in Epoch 2 respectively. Epoch 2 will contain two periods, period 1: dose adjustment period (first 12 weeks) and period 2: evaluation period (second 12 weeks).

Participant has been diagnosed with or has a malignancy (other than adequately treated basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix), unless the disease-free period prior to screening exceeds 5 years. Participant is receiving anti-coagulation therapy or has a history of thrombotic episodes (including deep vein thrombosis, myocardial infarction, cerebrovascular accident, pulmonary embolism) within 12 months prior to screening or a history of thrombophilia. Participant has abnormal protein loss (protein losing enteropathy, nephrotic syndrome). Participant has anemia that would preclude phlebotomy for laboratory studies according to standard practice at the site. Participant has an ongoing history of hypersensitivity or persistent reactions (urticaria, breathing difficulty, severe hypotension, or anaphylaxis) following IV immunoglobulin, SC immunoglobulin, and/or Immune Serum Globulin (ISG) infusions. Participant has immunoglobulin A (IgA) deficiency (IgA less than 0.07 g/L), known anti IgA antibodies, and a history of hypersensitivity. Participant is on preventative (prophylactic) systemic antibacterial antibiotics at doses sufficient to treat or prevent bacterial infections, and cannot stop these antibiotics at the time of screening. Participant has active infection and is receiving antibiotic therapy for the treatment of infection at the time of screening. Participant has a bleeding disorder, or a platelet count less than 20,000/ microliter (mcL), or, in the opinion of the investigator, would be at significant risk of increased bleeding or bruising as a result of subcutaneous therapy. Participant has total protein > 9 gram per deciliter (g/dL) or myeloma, or macroglobulinemia (IgM) or paraproteinemia. Women of childbearing potential meeting any one of the following criteria: Participant presents with a positive pregnancy test. Participant is breast feeding. Participant intends to begin nursing during the course of the study. Participant does not agree to employ adequate birth-control measures (e.g. intrauterine device, diaphragm or condom [for male partner] with spermicidal jelly or foam, or birth control pills/patches) throughout the course of the study. Participant has participated in another clinical study and has been exposed to an IP or device within 30 days prior to study enrollment. Participant is scheduled to participate in another non-observational (interventional) clinical study involving an IP or device during the course of the study. Participant has severe dermatitis that would preclude adequate sites for safe product administration.
