Ravulizumab-kontrollierte Nichtunterlegenheitsstudie zur Bewertung der Wirksamkeit und Sicherheit der Kombinationstherapie mit Pozelimab und Cemdisiran bei erwachsenen Patienten mit paroxysmaler nächtlicher Hämoglobinurie, die keine Komplement-Inhibitor-Behandlung erhalten haben oder kürzlich keine Komplement-Inhibitor-Therapie erhalten haben (ACCESS-1)

4. November 2026 aktualisiert von: Regeneron Pharmaceuticals

Eine randomisierte, offene, Ravulizumab-kontrollierte Nichtunterlegenheitsstudie zur Bewertung der Wirksamkeit und Sicherheit der Kombinationstherapie mit Pozelimab und Cemdisiran bei Patienten mit paroxysmaler nächtlicher Hämoglobinurie, die nicht mit Komplement-Inhibitoren behandelt wurden oder kürzlich keine Komplement-Inhibitor-Therapie erhalten haben

This study is researching a clinical treatment combination with two experimental drugs called pozelimab and cemdisiran. The study is focused on people with paroxysmal nocturnal hemoglobinuria (PNH). The aim of the study is to see how safe and effective the pozelimab + cemdisiran combination is for people with PNH and how the combination compares with 2 existing treatments: ravulizumab and eculizumab.

The pozelimab + cemdisiran combination may be referred to as "study drugs". Ravulizumab and eculizumab may also be called the "comparator drug".

The study is looking at several research questions, including:

  • How effective is the pozelimab + cemdisiran combination compared to ravulizumab?
  • How effective is pozelimab + cemdisiran combination compared to eculizumab?
  • What side effects may happen from taking the study drugs?
  • How much study drugs are in the blood at different times?
  • Whether the body makes antibodies against the study drugs (which could make the study drugs less effective or could lead to side effects)

Change in fatigue as measured by the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale
Zeitfenster: From baseline to week 26

Cohort A and B FACIT-Fatigue Scale is a 13-item, self-reported PRO measure assessing an individual's level of fatigue during their usual daily activities over the past week. This questionnaire is part of the FACIT measurement system, a compilation of questions measuring health-related quality of life (QoL) in patients with cancer and other chronic illnesses. The FACIT-fatigue assesses the level of fatigue using a Likert scale ranging from 0 (not at all) to 4 (very much). Scores range from 0 to 52, with higher scores indicating greater fatigue.

Participants rate items on a 4-point scale, with 1 as "not at all" and 4 as "very much."
