Studio di non inferiorità controllato con ravulizumab per valutare l'efficacia e la sicurezza della terapia di associazione con pozelimab e cemdisiran in pazienti adulti con emoglobinuria parossistica notturna che sono naive al trattamento con inibitori del complemento o che non hanno ricevuto di recente una terapia con inibitori del complemento (ACCESS-1)

4 novembre 2026 aggiornato da: Regeneron Pharmaceuticals

Uno studio di non inferiorità randomizzato, in aperto, controllato con Ravulizumab per valutare l'efficacia e la sicurezza della terapia di combinazione con Pozelimab e Cemdisiran in pazienti con emoglobinuria parossistica notturna che sono naive al trattamento con inibitori del complemento o che non hanno ricevuto di recente una terapia con inibitori del complemento

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
Lasso di tempo: 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.

Cohort A and B EORTC-QLQ-C30 is a 30-item subject self-report questionnaire composed of both multi-item and single scales, including global health status/quality of life, functional Scales (physical, role, emotional, cognitive, and social), symptom scales (fatigue, nausea and vomiting, and pain), and 7 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, sleep and financial difficulties). Participants rate items on a 4-point scale, with 1 as "not at all" and 4 as "very much."
