NCT02549170

Brief Summary

The aim of this study is to learn more about the following treatment options in adults with CIDP:

  • Subcutaneous self-infusion with HyQvia.
  • Intravenous infusion with Gammagard/Kiovig. Gammagard and Kiovig are the brand names for the same immunoglobulin compound. The study is in two parts. In Part 1, participants receive either HyQvia or a placebo subcutaneously. In Part 2 (only for participants who have a CIPD relapse during Part 1), participants will receive Gammagard Liquid/Kiovig intravenously. US participants will receive Gamunex-C. The first SC infusion will be given in the study clinic. The remaining SC infusions may be given in the study clinic or the participant's home. This will be decided by the study doctor and whether the participant or their caregiver can do the self-infusion.

Outcome Measures

Primary Outcomes (2)

  • Epoch 1: Relapse Rate

    Relapse rate is defined as the percentage of participants who experience a worsening of functional disability. Worsening of functional disability defined as an increase of \>=1 point relative to the pre- subcutaneous (SC) treatment baseline score in 2 consecutive adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) disability score. The INCAT disability score is an effective and responsive tool to assess clinical response to treatment in CIDP. The disability score ranges from 0 to 10 points, where 0 is normal (eg, no upper limb problems and walking not affected) and 10 is severely incapacitated (eg, inability to move either arm for any purposeful movement and restricted to wheelchair, unable to stand and walk a few steps with help).

    Week 32 End of Epoch 1 Treatment (EOET1)/Unscheduled relapse visit assessment (UV)/Early Termination (ET)

  • Epoch 2: Responder Rate

    Responder rate is defined as clinically meaningful improvement in functional ability defined as a decrease of \>=1 point in the adjusted INCAT disability score at the completion of the intravenous (IV) treatment period \[6 months\] or at the last study visit of the IV treatment period, relative to the pre-IV treatment baseline score.

    Up to 6 Months post-Epoch 1 (End of Epoch 2 Treatment [EOE2T])/Unscheduled visit assessment (UV)/Early Termination

IPD Sharing
Will share

Takeda provides access to the de-identified individual participant data (IPD) for eligible studies to aid qualified researchers in addressing legitimate scientific objectives (Takeda's data sharing commitment is available on https://clinicaltrials.takeda.com/takedas-commitment?commitment=5). These IPDs will be provided in a secure research environment following approval of a data sharing request, and under the terms of a data sharing agreement.

Shared Documents
STUDY PROTOCOL, SAP, ICF, CSR
Access Criteria
IPD from eligible studies will be shared with qualified researchers according to the criteria and process described on https://vivli.org/ourmember/takeda/. For approved requests, the researchers will be provided access to anonymized data (to respect patient privacy in line with applicable laws and regulations) and with information necessary to address the research objectives under the terms of a data sharing agreement.
