About this trial

The main aim of this study is to evaluate the pharmacokinetic (PK) comparability between TAK-881 and HYQVIA subcutaneous (SC) administration for maintenance therapy of CIDP.

The participants who are already receiving intravenous immunoglobulin G (IGIV), conventional subcutaneous intravenous immunoglobulin G (cIGSC), or HYQVIA will be treated with the same dose equivalent as their prior IG treatment with HYQVIA for 20 weeks followed by TAK-881 for 24 weeks.

Participants will need to visit the clinic every 3 or 4 weeks until they enter the extension phase. In the extension phase, home infusions are allowed, and visits will occur between every 12 weeks and 24 weeks.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Participant is willing and able to understand and fully comply with trial procedures and requirements, in the opinion of the investigator.

Participant has provided informed consent (that is, in writing, documented via a signed and dated informed consent Form [ICF]) and any required privacy authorization before the initiation of any trial procedures.

Participant has a documented diagnosis of CIDP or possible CIDP, as confirmed by a neurologist specializing/experienced in neuromuscular diseases and consistent with the European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) 2021 criteria.

Participant has responded to IgG treatment in the past (documented partial or complete resolution of neurological symptoms and deficits).

Disqualifiers

Participant with documented diagnosis of focal, multifocal, distal, or sensory CIDP, or possible focal, multifocal, distal, or sensory CIDP per the EFNS/PNS 2021 criteria.

Hereditary demyelinating neuropathies, such as hereditary sensory and motor neuropathy (HSMN), Charcot-Marie-Tooth (CMT) disease, and hereditary sensory and autonomic neuropathies (HSANs).

Neuropathies secondary to infections, disorders, or systemic diseases such as Borrelia burgdorferi infection (Lyme disease), diphtheria, systemic lupus erythematosus, POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes) syndrome, osteosclerotic myeloma, diabetic and non-diabetic lumbosacral radiculoplexus neuropathy, lymphoma, amyloidosis.

Multifocal motor neuropathy (MMN).

Trial design

Design model

Single group

Treatments tested in this trial

  • TAK-881

    Biological/Vaccine

    Participants will receive SC infusion of TAK-881.

  • HYQVIA

    Biological/Vaccine

    Participants will receive SC infusion of HYQVIA.

  • SC Investigational Needle Sets

    Device

    The single-use only SC needle set will be used to administer TAK-881/HYQVIA to the target depth below the skin surface. One needle set (single or bifurcated) will be used per infusion.
