慢性炎症性脱髄性多発根ニューロパチー患者におけるXEMBIFYとGamunex-Cの薬物動態および安全性を評価する研究 (XPERT)
慢性炎症性脱髄性多発根ニューロパチー患者におけるXEMBIFYとGamunex-Cの薬物動態および安全性を評価するためのオープンラベル多施設共同試験
The main goal of the study is to find out whether XEMBIFY, given once a week under the skin, provides similar levels of immunoglobulin G in the blood over time as Gamunex-C, which is given into a vein once every 3 weeks in people with CIDP.
Participants with CIDP will first have up to 28 days of screening to make sure they can join the study. Those who qualify will then start a 19-week treatment period with Gamunex-C. During this period, they will receive Gamunex-C through a vein once every 3 weeks, for a total of 7 doses. Approximately, one week after their last Gamunex-C dose, they will begin a 16-week treatment period with XEMBIFY under the skin, once a week for a total of 16 doses. Blood samples will be collected during both treatment periods to measure IgG level in the blood.

説明
Inclusion Criteria:
- Have typical CIDP or a CIDP variant according to the 2021 criteria established by the European Academy of Neurology/Peripheral Nerve Society (EAN/PNS). The level of diagnostic certainty may be CIDP or possible CIDP.
- Participants ≤ 90 kg in body weight and requiring an IGIV dose equivalent to 0.3-1.0 g/kg every three weeks (Q3W) inclusive and between 20-90 g of IGIV Q3W inclusive.
- Clinically stable on IGIV, defined as no recent change in CIDP treatment or experienced a CIDP relapse requiring treatment, within 12 weeks prior to Screening and through baseline visit.
Exclusion Criteria:
-
Diagnosis of polyneuropathy of any other cause (including multifocal motor neuropathy; monoclonal gammopathy of uncertain significance with anti-myelin-associated glycoprotein IgM antibodies; hereditary demyelinating neuropathy; polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes syndrome; lumbosacral radiculoplexus neuropathy; polyneuropathy associated with diabetes mellitus; polyneuropathy associated with systemic illnesses; or drug or toxin induced polyneuropathy).

-
Screening values of aspartate aminotransferase (AST) or alanine aminotransferase (ALT) levels exceeding ≥ 2.5 times the ULN for the expected normal range for the testing laboratory.
-
Hemoglobin levels < 10 g/dL at Screening.
-
Current administration of anti-coagulation therapy which would make IGSC administration inadvisable per investigator judgement (i.e., vitamin K antagonists, nonvitamin K antagonist oral anticoagulants [e.g., dabigatran etexilate targeting Factor IIa, rivaroxaban, edoxaban, and apixaban targeting Factor Xa], and parenteral anticoagulants [e.g., fondaparinux]).
