Ravulizumab-kontrollert ikke-inferioritetsstudie for å evaluere effektiviteten og sikkerheten til Pozelimab og Cemdisiran kombinasjonsterapi hos voksne pasienter med paroksysmal nattlig hemoglobinuri som er komplementhemmer-naive eller som ikke nylig har mottatt komplementhemmerbehandling (ACCESS-1)

4. november 2026 oppdatert av: Regeneron Pharmaceuticals

En randomisert, åpen etikett, ravulizumab-kontrollert, ikke-inferioritetsstudie for å evaluere effektiviteten og sikkerheten til kombinasjonsbehandling med Pozelimab og Cemdisiran hos pasienter med paroksysmal nattlig hemoglobinuri som er komplementhemmer-behandling-naive eller som ikke nylig har komplementert inhibitor.

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
Tidsramme: 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.

From baseline to week 26

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."

IPD-planbeskrivelse

All Individual Patient Data (IPD) that underlie publicly available results will be considered for sharing

IPD-delingstidsramme

When Regeneron has:

  • received marketing authorization from major health authorities (e.g., FDA, European Medicines Agency (EMA), Pharmaceuticals and Medical Devices Agency (PMDA), etc.) for the product and indication or has globally discontinued development of the product for all indications on or after April 2020 and has no plans for future development
  • made the study results publicly available (e.g., scientific publication, scientific conference, clinical trial registry),
  • the legal authority to share the data, and
  • ensured the ability to protect participant privacy.

Tilgangskriterier for IPD-deling

Qualified researchers can submit a proposal for access to individual patient or aggregate level data from a Regeneron-sponsored clinical trial through Vivli.
