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+)

2. november 2026 opdateret af: argenx

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.

    • Have been offered the participation in the OLE trial due to early termination of the ARGX-113-1802 trial (because sufficient events for the primary endpoint analysis of the that trial have been reached and it is stopped) and are considered to be eligible for treatment with efgartigimod PH20 SC treatment; or
    • Have completed the Week-48 visit of the previous cycle of the OLE trial and are considered to be eligible to continue with efgartigimod PH20 SC treatment.
  3. Women of childbearing potential who have a negative urine pregnancy test at baseline before IMP administration.

  4. Women of childbearing potential must use an acceptable method of contraception from signing the ICF until the date of the last administration of IMP.

Exclusion Criteria:

  1. Week-48/ED visit in the ARGX-113-1802 trial or the Week-48 visit of the previous OLE participation occurred more than 14 days prior to SD1 of the OLE trial or the start of a new treatment cycle in the OLE trial and more than 21 days since the last dose of IMP.
  2. Pregnant and lactating women and those intending to become pregnant during the trial.
  3. Patients with clinical evidence of other significant serious disease or patients who underwent a recent or have a planned major surgery, or patients who (intend to) use prohibited medications (see protocol) and therapies during the trial, or any other reason which could confound the results of the trial or put the patient at undue risk.

Change from baseline over time of the adjusted INCAT score
Tidsramme: Up to 48 weeks per cycle (each cycle is 48 weeks) until the end of the study

The Adjusted Inflammatory Neuropathy Cause and Treatment Disability Score (aINCAT) score is a 10-point scale that covers the functionality of legs and arms. The score varies between 0 and 10 (higher score, worse outcome).

Up to 48 weeks per cycle (each cycle is 48 weeks) until the end of the study
Change from baseline over time of the MRC Sum score
Tidsramme: Up to 48 weeks per cycle (each cycle is 48 weeks) until the end of the study

The Medical Research Council Sum Score evaluates motor strength. Evaluated on 6 muscle groups on each side, the score varies from 0 to 60 (lower score, worse outcome).

Up to 48 weeks per cycle (each cycle is 48 weeks) until the end of the study
Change from baseline over time of I-RODS disability scores
Tidsramme: Up to 48 weeks per cycle (each cycle is 48 weeks) until the end of the study

Inflammatory Rasch-built Overall Disability Scale (I-RODS) assesses the limitations of activities and social participation in patients with inflammatory neuropathies like CIDP. The score ranges from 0 to 100 (higher score, worse outcome).
