Reduzierung unerwünschter vaskulärer Ereignisse durch Faktor-XI-Hemmung bei erwachsenen Teilnehmern mit peripherer arterieller Verschlusskrankheit (ROXI-PALISADE)
Ein Masterprotokoll für eine Phase-3-, multizentrische, randomisierte Studie zur Bewertung der Wirksamkeit und Sicherheit von REGN7508 und REGN9933, monoklonalen Antikörpern gegen Faktor XI, bei Teilnehmern mit kürzlicher Revaskularisation der unteren Extremitäten bei symptomatischer peripherer arterieller Verschlusskrankheit (ROXI-PALISADE)
This study is researching 2 different experimental drugs called REGN7508 and REGN9933. The study is focused on people who have Peripheral Artery Disease (PAD), which means that the blood vessels in their arms and legs have become too narrow. People with PAD have a higher risk of getting blood clots after procedures like Lower Extremity Revascularization (LER), a procedure to improve blood flow in the legs and feet.
The aim of this study is to see how well REGN7508 and REGN9933 prevent life-threatening blood clots in participants with PAD who have recently had LER. The effects of REGN7508 and REGN9933, individually, will also be compared to rivaroxaban and a placebo.
The study is looking at several other research questions, including:
- What side effects might happen from taking the study drugs and how do they compare to the side effects of rivaroxaban
- How much study drug is in the blood at different times
- Whether the body makes antibodies against the study drugs (which could make the drugs less effective or could lead to side effects)
- If the study drugs affect the ability of the blood to clot normally

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