A Study of TAK-771 in Japanese People With Primary Immunodeficiency Diseases (PID)
A Phase 3, Open-label, Non-controlled Study to Evaluate the Pharmacokinetics, Safety and Tolerability, and Efficacy of TAK-771 in Japanese Subjects With Primary Immunodeficiency Diseases (PID)
The main aim of the study is to check how much TAK-771 stays in their blood over time, side effect from the study treatment or TAK-771, how much TAK-771 participants can receive without getting side effects from it, and if TAK-771 improves symptoms of primary immunodeficiency diseases (PID). This will help the study sponsor (Takeda) to work out the best dose to give people in the future.
The participants will be treated with TAK-771 for totally 27 or 30 weeks. Treatment period is consist of two periods called Epoch 1 and Epoch 2. In Epoch 1, different groups of participants will receive lower to higher doses of TAK-771 for 3 to 6 weeks. The study doctors will check for side effects from each dose of TAK-771. In Epoch 2, participants will receive TAK-771 once a 3 or 4 weeks until the end of 24 weeks.
There will be many clinic visits. The number of visits will depend on the infusion cycles of study drug (every 3, or 4 weeks).

|
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.

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 HR QoL.

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.

Treatment Satisfaction: Questionnaire for Medication-9 (TSQM-9)
Time Frame: Up to Week 31 for Participants with 4-Week Dosing Interval or Up to Week 28 for Participants with 3-Week Dosing Interval

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.

Treatment preference questionnaire is a self-administered questionnaire developed to assess participants' preference towards the administration of new subcutaneous immunoglobulin (SCIG) 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.
