Summary:

      In this study researchers want to learn about the safety of drug Osocimab at lower-dose and
      higher-doses in adult participants with kidney disease undergoing regular dialysis (a
      procedure that uses a machine to get rid of toxins and extra fluids in the blood). Patients
      with kidney disease undergoing regular dialysis are at high risk for heart and blood vessels
      diseases. Osocimab is a human monoclonal antibody under development for the prevention of
      events caused by blood clots like heart attack, stroke and death due to heart or blood
      vessels diseases. It works by binding to and blocking the activated form of clotting factor
      XI which increases the formation and stability of clots. Researchers also want to find out
      how drug Osocimab works in human body and how the body absorbs, distributes and excretes the
      drug.

      Participants in this study will receive monthly injection of either Osocimab at a lower-dose
      or higher-dose or placebo (a placebo looks like a treatment but does not have any medicine in
      it). Both Osocimab and placebo will be injected into the tissue under the skin of the belly.
      Observation for each participant will last up to 23 months. Blood samples will be collected
      from the participants to monitor the safety and measure the blood level of the study drug.
