TAK-881 在原发性免疫缺陷病 (PIDD) 参与者中的研究

2026年9月4日 更新者：Takeda

多中心、前瞻性、开放标签、随机、交叉研究，以评估 TAK-881 在原发性免疫缺陷病 (PIDD) 中的药代动力学 (PK)、安全性和耐受性

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.

详细说明

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).

Simulated AUC0-tau;ss of TAK-881 at Steady-State
大体时间：During the dosing interval of 6th dose (4-week): From Day 1 (pre and post infusion) every day up to 4 weeks

Sparse PK sampling was conducted for participants aged 2 to <16 years. A population PK model integrating PK data from participants aged 2 to <16 years and participants aged >=16 years was developed. Population PK simulations were performed using virtual pediatric and adult populations constructed from age- and sex-specific body weight distributions, ensuring that the simulations were representative of the target PIDD population. AUC0-tau;ss was estimated for the simulated PK profiles and summarized by age group. Geometric mean and 90% predicted interval (PI) derived from the simulation (N = 3000 per age group) at the observed median of average body weight adjusted TAK-881 full-dose per participant for every-4-week dosing frequency were reported.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
大体时间：From the start of study drug administration, up to 27 weeks (Single arm treatment) and up to 51 weeks (Crossover treatment)

An adverse event (AE) was any untoward medical occurrence in a clinical study subject, temporally associated with the use of the study intervention, whether or not the occurrence is considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of the study intervention. A TEAE was defined as any event emerging or manifesting at or after the initiation of treatment with a study intervention or medicinal product or any existing event that worsens in either intensity or frequency following exposure to the study intervention or medicinal product.

Number of Infusions Per Month at Full Dose With Both TAK-881 and HYQVIA
大体时间：Single arm treatment: Up to 20 weeks; Crossover treatment: Up to 45 weeks

Number of infusion per month at full dose was calculated as the total number of full dose infusions divided by the total time in months on treatment. A single aggregate value was therefore presented; a measure of dispersion was not applicable.

Monthly Infusion Time Per Participant at Full Dose With Both TAK-881 and HYQVIA
大体时间：Single arm treatment: Up to 20 weeks; Crossover treatment: Up to 45 weeks

大体时间：Single arm treatment: Up to 20 weeks; Crossover treatment: Up to 45 weeks

Number of infusion sites per infusion at full dose was calculated as the total number of full dose infusion sites divided by the total number of full dose infusions with an available infusion site. A single aggregate value was therefore presented; a measure of dispersion was not applicable.
Single arm treatment: Up to 20 weeks; Crossover treatment: Up to 45 weeks
Number of Infusion Sites (Needle Sticks) Per Month at Full Dose With Both TAK-881 and HYQVIA in All Participant
大体时间：Single arm treatment: Up to 20 weeks; Crossover treatment: Up to 45 weeks
