En studie för att utvärdera den långsiktiga säkerheten och effekten av en subkutan formulering av Efgartigimod hos vuxna med kronisk inflammatorisk demyeliniserande polyneuropati (CIDP, en autoimmun sjukdom som påverkar de perifera nerverna) (ADHERE+)
Open-label förlängning av ARGX-113-1802-studien för att undersöka den långsiktiga säkerheten, tolerabiliteten och effekten av Efgartigimod PH20 SC hos patienter med kronisk inflammatorisk demyeliniserande polyneuropati (CIDP)
This is the open-label extension study of phase II ARGX-113-1802 to evaluate the long-term safety and efficacy of the subcutaneous formulation of efgartigimod in adults with CIDP.
Patients already stabilized on efgartigimod PH20 SC will also have the opportunity to participate in a sub study to explore less frequent dosing of efgartigimod PH20 SC.
