En undersøgelse for at vurdere den langsigtede sikkerhed og effektivitet af en subkutan formulering af Efgartigimod hos voksne med kronisk inflammatorisk demyeliniserende polyneuropati (CIDP, en autoimmun sygdom, der påvirker de perifere nerver) (ADHERE+)
Open-label udvidelse af ARGX-113-1802-studiet for at undersøge den langsigtede sikkerhed, tolerabilitet og effektivitet af Efgartigimod PH20 SC hos patienter med kronisk inflammatorisk demyeliniserende 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.
