Un estudio para evaluar la seguridad y eficacia a largo plazo de una formulación subcutánea de efgartigimod en adultos con polineuropatía desmielinizante inflamatoria crónica (CIDP, un trastorno autoinmune que afecta los nervios periféricos) (ADHERE+)
Extensión abierta del ensayo ARGX-113-1802 para investigar la seguridad, tolerabilidad y eficacia a largo plazo de efgartigimod PH20 SC en pacientes con polineuropatía desmielinizante inflamatoria crónica (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.
