Study of 3 Monoclonal Antibodies (REGN9933, REGN7508, and REGN9533) in Adult Participants With End-Stage Kidney Disease on Hemodialysis
Sponsor: Regeneron Pharmaceuticals
Summary
This study will evaluate three Investigational Medicinal Products (IMPs) called REGN9933, REGN7508, and REGN9533. The study is focused on participants with End-Stage Kidney Disease (ESKD) treated with hemodialysis and standard anticoagulant treatment, such as heparin, to reduce the risk of blood clots as they can lead to serious health problems or be life-threatening. Because participants with ESKD who have hemodialysis have a higher risk of bleeding, the IMPs could be a meaningful new therapeutic option. The main aim of the study is to see what side effects may happen from taking REGN9933, REGN7508, or REGN9533. The study is looking at several other research questions, including: * How much IMP is in the blood at different times and * If the IMPs affect the ability of the blood to clot normally
Official title: A Master Protocol for a Phase 1b Double-Blind, Randomized Study to Assess the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of REGN9933 and REGN7508, Factor XI Monoclonal Antibodies, and REGN9533, a Factor XII Monoclonal Antibody, in Participants With End-Stage Kidney Disease on Hemodialysis
