OBJECTIVES:
I. Compare the response of previously untreated patients with chronic inflammatory demyelinating polyneuropathy to intravenous immune globulin vs. placebo.
PROTOCOL OUTLINE: This is a randomized, double-blind study. The first group receives intravenous immune globulin (IVIG) on days 1, 2, and 21; the second group receives an intravenous placebo on the same schedule.
Patients in either group may receive IVIG (same dosage as first group) after day 42.
Concurrent steroids and other immune globulin preparations are prohibited.
137 studies on the registry are indexed under Polyradiculoneuropathy, Chronic Inflammatory Demyelinating; 51 are open to participants now.
This study's enrollment of 90 is above the median of 37 across 85 interventional studies indexed under Polyradiculoneuropathy, Chronic Inflammatory Demyelinating.

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.
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.
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.
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.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
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.
