慢性免疫血小板减少症(ITP)的参与者对Efgartigimod IV的研究研究 (Advance Jr)
一个多中心,随机,双盲,平行臂,安慰剂对照,药代动力学和药效学研究,然后是一个开放标签的臂,以评估12岁至18岁以下的儿科参与者的Efgartigimod IV
The main purpose of this study is to confirm the correct dose of efgartigimod IV for treating patients aged 12 to younger than 18 years with chronic immune thrombocytopenia (ITP).
The study consists of a double-blinded treatment period (DBTP) in which the participants will be randomized in a 2:1 ratio to receive either efgartigimod IV or placebo IV. At the end of the treatment period (up to 24 weeks), all participants will receive efgartigimod IV during the first year open-label treatment period (OLTP1). At the end of the first OLTP1, participants may begin a second year (OLTP2). After the OLTP2, the participants will enter a follow-up period (approximately 8 weeks) while off study drug. The participants will be in the study for up to 138 weeks.

大体时间:Up to 76 weeks
|
The European Quality of Life 5 Dimensions 5 Level (EQ-5D-5L) is a questionnaire comprised of 5 dimensions. Participants are asked to select the statement in each dimension which best describes their health on the day they complete the questionnaire. Responses in each dimension are coded as a 1-digit number ranging from 1 (no problems) to 5 (extreme problems). |

Change from baseline in KIT Child Self-Report and KIT Parent Impact Report
大体时间:Up to 76 weeks
|
The Kids' ITP Tools (KIT) comprises two disease- specific tools: a self-report form for children aged 12 and older, and a parent impact form. Respondents provide insights into their disease experience using a 1-week recall period. The instrument generates a total score, calculated by summing the items and converting them to a scale of 0 to 100, where higher scores reflect a better disease-specific quality of life (QoL). |

In all participants, the pediatric Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) will use to assess health-related quality of life (HRQoL) before and after treatment. The FACIT-F questionnaire has a score range of 0 to 52, where 0 represents the worst possible fatigue and 52 indicates no fatigue. |
