Key inclusion & exclusion criteria
Inclusion criteria:
Subjects meeting all of the following inclusion criteria may be enrolled into the study:
• IVIG-untreated subjects: either subjects with newly diagnosed CIDP (developing
over at least 2 months) or subjects with an IVIG treatment interruption for at least 1
year with a progressive disease (deteriorating in the last 2 months) prior to
enrolment
OR
IVIG-pretreated subjects being treated regularly with IVIG:
- on a fixed cycle length of 2 to 6 weeks ± 5 days in the last 6 months
- on a fixed dosage of ± 20 % in the last 6 months
- deteriorating by at least 1 INCAT score point during the Washout Period of up to 10
weeks (except for an increase from 0 to 1 solely due to upper limb score).
• Diagnosis of CIDP with progressive or relapsing dysfunction from motor and sensory
or symmetric motor nerve only in at least 1 limb resulting from neuropathy. Criteria
for definite or probable CIDP according to EFNS/PNS guideline.
- IVIG-untreated subjects need an actual diagnosis including electrophysiology.
- IVIG-pretreated subjects need a historic diagnosis.
• Age =18 years.
• Male or female.
• Written informed consent for study participation obtained before undergoing any
study specific procedures.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion criteria:
Subjects meeting any of the following exclusion criteria must not be enrolled into the study:
• A motor syndrome that fulfils criteria for multifocal motor neuropathy (MMN) with
conduction block (i.e., upper limb motor weakness without sensory deficit and with a
50% decrease in action potential amplitude or area on proximal compared with distal
stimulation in motor nerves).
• CIDP with monoclonal gammopathy of uncertain significance (CIDP-MGUS) with anti-
MGUS antibodies and patients with distal acquired demyelinating symmetric (DADS)
neuropathy.
• Any disease (mainly neurological or chronic orthopedic) that may cause symptoms or
may interfere with treatment or outcome assessments with the INCAT (e.g.,
diphtheria, drug or toxin exposure and diabetes mellitus likely to have caused the
neuropathy, IgM paraproteinemia, familial neuropathy, borreliosis with
radicolopathy, post-polio-syndrome, M. Parkinson, stroke).
• Current malignancy.
• History of cardiac insufficiency (New York Heart Association [NYHA] III/IV),
cardiomyopathy, significant cardiac dysrhythmia requiring treatment, unstable or
advanced ischemic heart disease, congestive heart failure or severe hypertension.
• History of thrombotic episodes (deep vein thrombosis, myocardial infarction,
cerebrovascular accident).
• Migraine associated with IVIG infusion in the last 3 months prior to enrolment.
• Known allergic or other severe reactions to blood products including intolerability to
previous IVIG (i.e. severe headache, hypersensitivity, intravascular hemolysis).
• Subjects with serum IgA level less than 50% of the lower normal limit.
• Known hyperprolinemia.
• Any condition (including alcohol, drug or medication abuse) that is likely to interfere
with evaluation of the study product or satisfactory conduct of the study.
• Plasma exchange 3 months prior to enrolment.
• Treatment with immunomodulatory agents others than steroids, methotrexate or
azathioprine (e.g. interferon, TNF-a inhibitors) within 6 months before enrolment.
• Treatment with rituximab in the 12 months before enrolment.
• Abnormal laboratory parameters: creatinine > 1.5 times the upper normal limit (UNL),
lactate dehydrogenase (LDH) > 1.5 times the UNL, C-reactive protein (CRP) > 1.5
times the UNL, hemoglobin (Hb) < 10 g/dL.
• Ongoing HIV, hepatitis C and hepatitis B infection.
• Participation in another clinical study (or use of another investigational medicinal
product [IMP]) within 3 months prior to enrolment.
• Not able to comply with study procedures and treatment regimen.
• Employee at the study site, or spouse/partner or relative of any study staff (e.g.,
investigator, sub-investigators, or study nurse).
• Pregnancy or nursing mother.
• Intention to become pregnant during the course of the study.
• Female subjects of childbearing potential either not using, or not willing to use, a
medically reliable method of contraception for the entire
duration of the study, or not sexually abstinent for the entire duration of the study,
or not surgically sterile.

Intervention(s)

Trade Name: Privigen®
Pharmaceutical Form: Solution for infusion
INN or Proposed INN: Human normal immunoglobulin G (IgG > 98% purity)
CAS Number: 0
Other descriptive name: HUMAN NORMAL IMMUNOGLOBULIN (IV)
Concentration unit: % percent
Concentration type: equal
Concentration number: 10-

Primary Outcome(s)
Main Objective: The objective of the study is to demonstrate the efficacy and safety of Privigen in subjects with CIDP.
Primary end point(s): The primary efficacy endpoint will be the responder rate (ie, percentage of responders) based on the Inflammatory Neuropathy Cause and Treatment (INCAT) score, using the following definitions:
• Responders are defined as those subjects who demonstrate a “clinically meaningful
improvement”1) between baseline and Week 25.
• Non-responders are defined as those subjects who fulfill 1 of the following 2
conditions:
a. Subjects who demonstrate no “clinically meaningful improvement” between
baseline and Week 25, OR
b. Subjects who are withdrawn from the study for any reason after the start of
Privigen treatment without “clinically meaningful improvement”1) at the last
study visit.
1) “Clinically meaningful improvement” at a subject level is set at a decrease of at
least 1 INCAT score point (except for a change of 1 to 0 solely due to upper limb
score).
Secondary Objective: Not applicable.
