Study summary

This study is an extension study to the pivotal study IgPro20_3003 (NCT01545076). The purpose of this extension study is to investigate the long-term treatment of CIDP with IgPro20, with regard to safety and efficacy.

Subjects who have completed subcutaneous (SC) Week 25 or were successfully rescued from a CIDP relapse during the SC Treatment Period of pivotal study IgPro20_3003 (NCT01545076) will have the option to receive open-label low-dose IgPro20 (0.2 g/kg bodyweight [bw]) weekly for up to 48 weeks. Subjects relapsing on low-dose IgPro20 will either return to high-dose IgPro20 (0.4 g/kg) immediately or be discontinued, depending on investigator's judgment. Subjects returning to high-dose IgPro20 will continue on high-dose until they have completed a total of 48 weeks of IgPro20 treatment. If subjects do not successfully recover from CIDP relapse within 4 weeks, they will be withdrawn.

The treatment duration will be up to 48 weeks, followed by a completion visit (week 49).

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Subjects having completed the pivotal study IgPro20_3003 (SC Week 25) or successfully rescued from a CIDP relapse during the SC Treatment Period of pivotal study IgPro20_3003 (NCT01545076).
  • Written for study participation obtained before undergoing any study-specific procedures.

Exclusion criteria

Exclusion Criteria:

  • Subject is unable to directly transition from study IgPro20_3003.
  • New medical condition and/or social behavior (ie, alcohol, drug, or medication abuse) during participation in study IgPro20_3003 that in the judgment of the investigator could increase risk to the subject, interfere with the evaluation of medicinal product, and/or conduct of the study.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

    IgPro20

    20% liquid formulation (200 mg/mL) of human normal immunoglobulin for SC use administered SC weekly: 0.2 g/kg bw (low-dose IgPro20) for up to 48 weeks. Subjects who experience CIDP relapse on 0.2 g/kg IgPro20 will have an increase to 0.4 g/kg IgPro20 immediately and will continue on high-dose until they have completed a total of 48 weeks of IgPro20 treatment.

Interventions

What researchers measure

Primary outcomes

  1. Number of Adverse Events (AEs) Per Infusion

    Time frame: Up to 49 weeks

Secondary outcomes

  1. Time to First CIDP Relapse

    Time to first CIDP relapse based on adjusted INCAT score, using the Kaplan-Meier estimator. Relapse is defined as an increase of at least 1 INCAT score point (except for the increase from 0 to 1 in the upper limb score only).

    Time frame: Up to 49 weeks

  2. Change From Baseline in CIDP Total Adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) Score

    The INCAT score is a 10-point scale that covers the functionality of legs and arms, and has been successfully used to measure treatment effects in various CIDP studies. Scores for arm disability range from 0 ("No upper limb problems") to 5 ("Inability to use either arm for any purposeful movement"), and scores for leg disability range from 0 ("Walking not affected") to 5 ("Restricted to wheelchair, unable to stand and walk a few steps with help"). The INCAT (total) score is the sum of these 2 scores and ranges from 0 to 10. For the "adjusted" INCAT score, changes in the function of the upper limbs from 0 (normal) to 1 (minor symptoms) or from 1 to 0 were not recorded as deterioration or improvement because these changes are not considered clinically significant.

    Time frame: Baseline and up to 49 weeks

  3. Change From Baseline in Medical Research Council (MRC) Score

    An adapted version of the MRC sum score as published by Kleyweg and the RMC trial group was used. With the MRC sum score, the following 8 bilateral muscle pairs were assessed, and individual muscle scores as well as the sum score documented: Shoulder abduction; Elbow flexion; Wrist extension; Index finger abduction; Hip flexion; Knee extension; Foot dorsiflexion; Great toe dorsiflexion. The MRC sum score ranges from 0 (paralysis) to 80 (normal strength) points.

    Time frame: Baseline and up to 49 weeks

  4. Change From Baseline in Rasch-built Overall Disability Scale (R-ODS)

    The R-ODS is a recently published outcome measure that captures activity and social participation in subjects with Guillain-Barré Syndrome, CIDP, and monoclonal gammopathy of uncertain significance. The 24-item questionnaire covers a wide range of tasks of daily life that are each to be rated as "impossible to perform", "able to perform with difficulty", or "easy to perform" (scale of 0 - 2 points respectively). Items are sorted in order of increasing difficulty to perform, based on data from subjects with peripheral neuropathies (chronic inflammatory demyelinating polyneuropathy, Guillain-Barré Syndrome, or monoclonal gammopathy of uncertain significance) and subjects recruited at the university outpatient clinics of Rotterdam and Maastricht.

    Time frame: Baseline and up to 49 weeks

  5. Change From Baseline in Mean Grip Strength

    The hand-held Vigorimeter from Martin (Tuttlingen, Germany) is a device that measures the strength of small muscles in the hand, ie, grip strength. The subject squeezes a rubber bulb lying between the palm of the hand and the thumb and index fingers. The pressure is recorded via a rubber tube on a nanometer and expressed in kilopascal (kPa). At each assessment, the subject squeezes 3 times with each hand.

    Time frame: Baseline and up to 49 weeks

  6. Percentage of Subjects With Adverse Events (AEs)

    Time frame: Up to 49 weeks

  7. Number of AEs by Severity Per Infusion

    Time frame: Up to 49 weeks

  8. Percentage of Subjects With AEs by Severity

    Time frame: Up to 49 weeks

  9. Number of Causally Related AEs Per Infusion

    Time frame: Up to 49 weeks

  10. Percentage of Subjects With Causally Related AEs

    Time frame: Up to 49 weeks

  11. Number of Serious AEs Per Infusion

    Time frame: Up to 49 weeks

  12. Percentage of Subjects With Serious AEs

    Time frame: Up to 49 weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 2, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
