E.4 | Principal exclusion criteria |
A patient may be included in the study if none of the following criteria is met: 1. Upper motor neuron, bulbar, cranial nerve or significant sensory deficit. 2. CSF protein >100 mg/dL (if available and done as part of a previous evaluation). 3. Any other ongoing disease that may cause chronic peripheral neuropathy, such as toxin exposure, dietary deficiency, uncontrolled diabetes, hyperthyroidism, cancer, systemic lupus erythematosus or other connective diseases, infection with HIV, hepatitis B virus (HBV), or hepatitis C (HCV), Lyme disease, multiple myeloma, Waldenström's macroglobulinaemia, amyloid, and hereditary neuropathy. 4. BMI ≥ 40 kg/m2. 5. Known hypersensitivity to the active substance or to any of the excipients of I10E (glycine and polysorbate 80) or Kiovig® (glycine). 6. Patients who have been treated with Kiovig® shall not have received Kiovig® during the last 6 months prior to enrolment. 7. History of IgA deficiency, except if the absence of anti-IgA antibodies is documented. 8. Protein-losing enteropathy characterised by serum protein levels <60 g/l and serum albumin levels <30 g/l . 9. History of cardiac insufficiency (New York Heart Association (NYHA)III/IV) , uncontrolled cardiac arrhythmia, unstable ischemic heart disease, or uncontrolled hypertension. 10. History of venous thrombo-embolic disease, myocardial infarction or cerebrovascular accident. 11. Risk factor for blood hyperviscosity such as cryoglobulinemia or haematological malignancy with monoclonal gammopathy. 12. History of kidney transplantation, nephrotic syndrome (defined as proteinuria >3.5 g per 24 hours accompanied by hypoalbuminemia and edema), or any acute or chronic kidney disease that in the opinion of the investigator and/or nephrologist would preclude the use of I10E and/or interfere with the assessment of the safety and efficacy of I10E. AND/OR Chronic kidney disease (CKD) for more than 3 months as documented by at least one of the following: - glomerular filtration rate (GFR) <60 mL/min/1.73m2 measured according to the Modified Diet in Renal Disease (MDRD) formula AND/OR - urine protein reagent strip: 2 crosses AND/OR - urine protein reagent strip: one cross with one of the following: *albumin excretion rate (AER) >300 mg/24 hours or protein excretion rate (PER) >500 mg/24 hours (24h-urine collection) OR *albumin to creatinine ratio (ACR) >30 mg/mmol or protein to creatinine ratio (PCR) >50 mg/mmol (spot urine sample). 13. Serum levels of AST, or ALT and/or ALP >2 times upper limit of normal range. 14.

Effective contraception are injectable, patch or combined oestro-progestative or progestative contraceptives, Copper T or levonorgest releasing intra-uterine devices, depot intramuscular medroxyprogesterone, subcutaneous progestative contraceptive implants, condoms or occlusive caps (diaphragm or cervical/vault caps) with spermicide, true abstinence (when this is in line with the preferred and usual lifestyle of the patient). 18. Any serious medical condition that would interfere with the clinical assessment of I10E or prevent the patient from complying with the protocol requirements. 19. Anticipated poor compliance of patient with study procedures during the 12 month duration of the study. 20. Drug or alcohol abuse. |

E.5 End points |
E.5.1 | Primary end point(s) |
Difference between I10E and Kiovig® in the mean assessments of the original MMRC 10 sum score (10 muscles on both sides see Table 20.1) described by Cats 2008 during the evaluation period (i.e. 13 weeks after the initiation of either I10E or Kiovig® until the end of the respective treatment period). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |

|
E.5.2 | Secondary end point(s) |
Difference between I10E and Kiovig® in the mean assessments of the following parameters during the evaluation period (i.e. 13 weeks after the initiation of either I10E or Kiovig® until the end of the respective treatment period): • MMRC 10 new sum score (10 slightly different muscles on both sides chosen because they are expected to be more relevant and responsive to change; see Table 20.1) • Rasch built MMRC sum score (based on the 10 muscles in the MMRC sum score described by Cats 2008) • MMRC 14 sum score (14 muscles on both sides) • Grip strength with dynamometer in the most affected hand • Need for change of the IVIG dose or frequency due to a worsening of the patient's neurological status with IMPs during the respective treatment period. • Change of Clinical Global Impression (CGI) during respective treatment periods. • Discontinuation of study treatment during the respective treatment period. • INCAT: upper and lower limbs |
