NCT ID: NCT05755035

Last Updated: 2026-02-03

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2/PHASE3
• Total Enrollment: 65 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2023-10-24
• Study Completion Date: 2026-01-20

Brief Summary

The main aim of this study is to evaluate the PK, safety, tolerability and immunogenicity of subcutaneous (SC) administration of TAK-881 in adult and pediatric participants with PIDD and compare them to HYQVIA in participants 16 years old and older.

The participants will be treated with TAK-881/HYQVIA or HYQVIA/TAK-881 with the same dose and dosing interval of immunoglobulin for up to 51 weeks (for participants greater than or equal to [>=]16 years) and only with TAK-881 for up to 27 weeks (for participants aged 2 to less than [<]16 years) as they were treated with another immunoglobulin before enrollment. Participants will need to visit the clinic every 3 or 4 weeks during the duration of the study.

Detailed Description

The study consists of a screening epoch, a ramp-up epoch (if needed) and treatment epochs. Participants who have been receiving conventional subcutaneous intravenous immunoglobin G (cIGSC) or intravenous immunoglobulin G (IGIV) before the study, will enter a ramp-up epoch which will start 1, 2, 3 or 4 weeks after the last cIGSC or IGIV pre study dose before screening. Participants who have already been receiving HYQVIA treatment before the study, will directly enter the treatment epochs after screening. Participants aged greater than or equal to [>=]16 years will be randomized at a 1:1 ratio to one of the following treatment sequences: either TAK-881 followed by HYQVIA or HYQVIA followed by TAK-881. Each participant aged >=16 years will complete both crossover epochs. Pediatric participants aged 2 to less than [<]16 years will complete a single arm treatment with the study drug (TAK-881 only).

Eligibility Criteria

Inclusion Criteria

• Participant must have a documented diagnosis of a form of primary humoral immunodeficiency involving a defect in antibody formation and requiring IgG replacement, as defined according to the International Union of Immunological Societies (IUIS) Committee.
• Participant is 2 years to <16 years at the time of signing the informed consent form (ICF) for the single arm treatment part of the study OR 16 years or older at the time of signing the ICF for the crossover part of the study.
• Participant has received a stable dose of regular treatment with any IGIV OR HYQVIA with a treatment interval of every 21 or 28 days OR any cIGSC with a treatment interval of every 7 or 14 days over a period of at least 12 weeks prior to screening at a minimum prestudy IgG dose equivalent to 0.3 grams per kilograms per body weight per 4 weeks (g/kg BW/4 weeks) and a maximum dose equivalent to 1 g/kg BW/4 weeks. Over that period, the participant should have been on the same product of IGIV, HYQVIA, or cIGSC. A stable dose is defined as one that deviates less than +-25 percentage (%) from the mean dose for all IgG infusions within this 12-week period prior to screening. Variations in the treatment interval of up to +-5 days for participant with a 28-day treatment interval and of up to +-3 days for participant with a 7, 14, or 21-day treatment interval are acceptable up to the first IP infusion.
• Participant has a serum trough level of IgG greater than (>) 5 grams per liter (g/L) at the following time points:

1. At screening (sample taken prior to prestudy IgG infusion after signing the ICF) and

2. Within 12 weeks prior to screening.

• If female of childbearing potential, participant presents with a negative pregnancy test and agrees to employ highly effective form of contraception for the duration of the study.
• Participant, or in the case of minors, legally designated representative(s) is/are willing and able to comply with the requirements of the protocol, including PK blood sampling, for the duration of the study.

Informed Consent
