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

  1. Age ≥2 years and ≤17 years.
  2. Patients with a diagnosis of CIDP based on European Academy of Neurology/Peripheral Nerve Society (EANPNS) 2021 guidelone [1]
  3. Clinical history of functional impairment due to CIDP, corresponding to an mRS score ≥2, but ≤5.
  4. Voluntarily given written (provided by patient's parent or legal guardian) and assent (provided by the patient, if age appropriate per Independent Ethics Committee [IEC]/Institutional Research Board [IRB] requirements).

Exclusion criteria

Exclusion Criteria:

  1. Patients with previously diagnosed CIDP who lack any CIDP symptoms.
  2. Patients with a known history of inherited neuropathy or a family history of inherited neuropathy.
  3. Patients who have previously failed immunoglobulin therapy for CIDP.
  4. Patients who received immunoglobulin or plasma exchange (PEX) within eight weeks prior to the Baseline Visit (washout phase). However, if a patient has clinical evidence of confirmed CIDP relapse during the phase (consistent with an increase in mRS of ≥1), they are eligible for trial enrolment.
  5. Patients with a history of deep vein thrombosis (DVT) in the past year, or pulmonary embolism ever.
  6. Patients on unstable (change in prescribed dose within the last eight weeks) or rituximab use.
  7. Patients with known or suspected , anaphylaxis, or severe systemic response to immune-globulins, blood or plasma derived products, or any component of PANZYGA.
  8. Female patients who are breastfeeding, pregnant, or planning to become pregnant, or are unwilling to use an effective method while on the study (acceptable methods of birth control for this study include: intrauterine device [IUD], hormonal contraception, male or female condom, spermicide gel, diaphragm, sponge, or cervical cap).
  9. Presence of medical history information or clinical symptoms suggestive of (HIV), virus (HBV), and/or virus (HCV) infections.
  10. Severe liver and/or kidney disease ( [ALT] > 3 × [ULN]; aspartate aminotransferase [AST] > 3 × ULN; and/or creatinine levels >44 µmol/L for children ages 2-3 years, >62 µmol/L for children ages 4-10 years, and >89 µmol/L for children ages 11-17 years.
  11. Presence of medical history information or clinical symptoms suggestive of immunoglobulin (IgA) deficiency and antibodies against IgA.
  12. History of alcohol or drug abuse in the previous year, per Investigator's opinion.
  13. Unable or unwilling to comply with the study protocol.
  14. Receipt of any other medicinal product (IMP) within three months before study entry or participating in another interventional clinical study. Prior participation in an observational or open-label study involving an approved product may be allowed but require prior consultation with the Medical Monitor to assess eligibilty.
  15. Any other condition(s) that, in the Investigator's opinion, makes it undesirable for the patient to participate in the study or may interfere with protocol compliance.
Terms in these criteria, in plain language(11)

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.

Washout period

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

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.

What researchers measure

Primary outcomes

  1. Change in CIDP Baseline

    Evaluate the efficacy of two PANZYGA dose regimens in pediatric CIDP patients based on change in CIDP symptoms, measured by the Modified Rankin Score. The Modified Rankin Score (mRS) is a 6 point disability scale with possible scores ranging from 0 to 6.

    Time frame: Up to 24 weeks

Secondary outcomes

  1. CIDP Relapse

    Evaluate percentage of patients with CIDP relapse between 2 doses of Panzyga with relapse defined as increase in Modified Rankin score by ≥1 point from the baseline score related to CIDP. The Modified Rankin Score (mRS) is a 6 point disability scale with possible scores ranging from 0 to 6.

    Time frame: Up to 24 weeks

  2. Time to CIDP Relapse

    Time to CIDP relapse or withdrawal for any other reason with with relapse defined as increase in Modified Rankin Score score by ≥1 point from the baseline score. The Modified Rankin Score (mRS) is a 6 point disability scale with possible scores ranging from 0 to 6.

    Time frame: Up to 24 weeks

  3. Percentage of Patients With Good/Excellent Response

    The percentage of patients with good/excellent response, defined by a Modified Rankin Score score of 0 or 1 in each arm at Week 24. The Modified Rankin Score (mRS) is a 6 point disability scale with possible scores ranging from 0 to 6.

    Time frame: Up to 24 weeks
