End Stage Renal Disease Requiring Hemodialysis
Conditions
Keywords
End stage renal disease (ESRD), Hemodialysis (HD), Thrombotic Events
Brief summary
Patients whose kidneys are no longer able to work as they should and require treatment to filter wastes from the blood (hemodialysis) are at high risk for blood clots that form in blood vessels (thrombosis) blocking blood flow that causes heart attacks, strokes, and other life-threatening conditions. BAY2976217 is under clinical development for prevention of thrombosis. The goal of the study is to learn more about the safety of BAY2976217, how it is tolerated and the way the body absorbs, distributes and gets rid of the study dug given as multiple doses in participants with renal impairment who require hemodialysis.
Interventions
Study intervention will be injected subcutaneously.
Matching placebo to BAY2976217 will be injected subcutaneously.

Trough Concentrations (Ctrough) of Three Dose Levels of Fesomersen
Trough (pre-dose) fesomersen-equivalent plasma concentrations (Ctrough) for 3 dose levels of fesomersen were summarized descriptively by dose level and visit: Visit 12, Visit 14, Visit 16, Visit 18 (main treatment period). Ctrough was not measured for the placebo group.
Time frame: At visits V12 (Day 57), V14 (Day 85), V16 (Day 113), V18 (Day 141)
Population: Pharmacokinetic analysis set (PKS) includes all fesomersen-treated participants with at least 1 PK sample in accordance with the PK sampling schedule and without deviation from the protocol that would interfere with the evaluation of the PK data were included in the PK analysis. Only those participants who have sample collection with data available at the specified time points were analyzed.
