Primary Immunodeficiency Diseases (PID)
Conditions
Brief summary
The main aim of this study is to learn if TAK-881 is safe and well tolerated during long-term use in adults and children with PIDD who are eligible and completed study TAK-881-3001 (NCT05755035). The participants will receive the first dose of TAK-881 immunoglobulin (IgG) infusion at the same dosage as the last dose administered in study TAK-881-3001 (NCT05755035). After the first TAK-881 infusion in study TAK-881-3002, the dosing interval (can be adjusted by participant/caregiver) and/or the dose of TAK-881 can be adjusted by the study doctor to every 2, 3 or 4 weeks at scheduled site visits. Participants will visit the clinic every 12 weeks until the End of Study (EOS) visit.
Detailed description
The study consists of two Epochs: Epoch 1 and Epoch 2. In Epoch 1 eligible participants will have the opportunity to receive TAK-881 for a minimum of 6 months. After 6 months in study TAK-881-3002, the results of the anti-rHuPH20 binding antibody assay from either study TAK-881-3001 (NCT05755035) or study TAK-881-3002 (Epoch 1) will be used to determine the next steps in the study: * Epoch 1: Participants with an anti-rHuPH20 antibody titer less than \[\<\] 1:160 will complete the EOS visit on the day of the first non-investigational product (IP) infusion following Study Visit Week 25. * Epoch 2: Participants with an anti-rHuPH20 antibody titer greater than or equal to \[\>=\] 1:160 at any time point during Study TAK-881-3001 (NCT05755035) and/or study TAK-881-3002 (Epoch 1), will continue with an additional two years of TAK-881 treatment and undergo safety follow-up and will complete the EOS visit on the day of the first non-IP infusion following study Visit Week 121.
Interventions
Participants will receive SC infusion of TAK-881.
The single-use only SC needle set will be used to administer TAK-881 to the target depth below the skin surface. One needle set (single or bifurcated) will be used per infusion.

| Treatment Satisfaction Questionnaire for Medication (TSQM-9) Scores in Participants Aged >=16 Years | From Week 13 up to Week 121 | TSQM-9 is a 9-item, validated, self-administered instrument to assess participants satisfaction with medication. It consists of 3 subscales: effectiveness, convenience and global satisfaction. The item scores of each of the 3 domains are summed and transformed to create a total score of 0 (extremely dissatisfied) to 100 (extremely satisfied). Higher score indicates greater satisfaction in that domain. |
| Health-Related Quality of Life (HRQoL): EuroQol 5 Dimension 5 Level Questionnaire (EQ-5D-5L) Score in Participants Aged >=12 Years | From Baseline up to Week 121 | The EQ-5D-5L is a validated, self-administered assessment of overall health designed by the EuroQol Group. The instrument consists of two components: the EQ-5D descriptive system and the standard vertical EQ visual analogue scale (EQ-VAS). The descriptive system consists of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). Each dimension has five response categories: no problems, slight problems, some or moderate problems, severe problems, or extreme problems. Participants will be asked to describe their health state that day by choosing one of 5 responses that reflect the levels of severity for each of the 5 dimensions. The EQ-VAS measures one's self-perceived health today on a vertical scale from 0 (worst imaginable health) to 100 (best imaginable health) on which participants have to indicate their current health. Higher score indicates best health status. |
| Treatment Preference Measured by a Disease-specific Questionnaire for Participants and the Investigational Medical Device Using TAK-881 in Participants Aged >=12 Years | At Weeks 25 and 73 | The disease-specific treatment preference questionnaire is a self-administered, non-validated scale to assess participant preference for various attributes of IgG therapy and accompanying devices, such as ease of use of administration of TAK-881 complexity of administration, and convenience. The questionnaire consists of two components. The first component asks participants to indicate the extent to which they like or dislike aspects of TAK-881, including treatment frequency, time, ease, convenience, and complexity. Each item has five response categories: like very much, like, no preference, dislike, and dislike very much. The second component is a single question asking whether they would choose to continue receiving treatment after the trial ends. |
