Behandling og sekundær forebyggelse af venøs tromboembolisme (VTE) hos voksne deltagere med solide og hematologiske cancerformer (ROXI-CAT-II)
Et 2-delt, fase 3, multicentrisk, randomiseret, åben-label, aktivt kontrolleret studie til vurdering af effektivitet og sikkerhed af REGN7508, en monoklonal antistof mod faktor XI, til behandling og sekundær forebyggelse af venøs tromboemboli hos deltagere med solide og hematologiske kræftformer (ROXI-CAT-II)
This study is researching an experimental drug called REGN7508 (called "study drug") and will consist of 2 parts: Part 1 and Part 2. The study is focused on participants with or without cancer who develop blood clots in certain veins (called Deep Vein Thrombosis [DVT]) that block blood flow (Part 1) or focused on participants with cancer who develop blood clots in certain veins (DVT) or the lungs (also called Pulmonary Embolism [PE]) (Part 2).
The aim of the study is to see how safe and effective the study drug is at treating and preventing further blood clots in participants with or without cancer (Part 1) or in participants with cancer (Part 2) compared with another treatment (apixaban).
The study is looking at several other research questions, including:
- What side effects may happen from taking the study drug
- How much study drug is in the blood at different times
- Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)

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
IPD-delingsadgangskriterier
Qualified researchers can submit a proposal for access to individual patient or aggregate level data from a Regeneron-sponsored clinical trial through Vivli. Regeneron's Independent Research Request Evaluation Criteria can be found at: https://www.regeneron.com/sites/default/files/Regeneron-External-Data-Sharing-Policy-and-Independent-Research-Request-Evaluation-Criteria.pdf
