Intravenous immunoglobulin (IVIg) is well-established in the treatment of patients with chronic inflammatory demyelinating polyneuropathy (CIDP). Immune globulin subcutaneous (human) 20% liquid (Hizentra®; referred to as IgPro20 hereafter) has recently been approved in a number of countries, including the USA and those of the EU, as maintenance therapy in patients with CIDP. In the pivotal phase III PATH trial in adults with CIDP who were first stabilized on IVIg therapy, maintenance therapy with IgPro20 for 24 weeks significantly reduced CIDP relapse or study withdrawal rates versus placebo. Efficacy was sustained during ≤ 48 weeks of additional treatment with IgPro20 in the open-label PATH extension study. IgPro20 was generally well tolerated, with low rates of systemic adverse events (AEs); the most common AEs were local reactions (e.g. infusion-site erythema, infusion-site swelling). In PATH, more than one-half of IgPro20 recipients preferred this therapy to their previous IVIg therapy. IgPro20 offers a convenient alternative to IVIg with a better systemic AEs profile and thus extends the options for maintenance therapy in CIDP.
