Factor XI LICA to Reduce Events Such as Heart Attack and Stroke in Patients Whose Kidneys Are no Longer Able to Work as They Should and Require Treatment to Filter Wastes From the Blood: Focus is on the Safety of BAY2976217 and the Way the Body Absorbs, Distributes and Removes the Study Drug

Phase 2
Completed
Conditions
End Stage Renal Disease Requiring Hemodialysis
Interventions
Drug: Fesomersen sodium (BAY2976217)
Drug: Placebo
Registration Number
NCT04534114
Lead Sponsor
Bayer
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.

Primary Outcome Measures
NameTimeMethod
Incidence of Composite of Major Bleeding (MB) and Clinically-relevant Non-major Bleeding (CRNMB) During the Main Treatment Period and Within the On-treatment Time Window, as Assessed by Blinded Central Independent Adjudication Committee (CIAC)Up to 24 weeks

MB is defined as symptomatic bleeding and: 1) Fatal bleeding, and/or; 2) Bleeding in a critical area or organ, such as intracranial, intraspinal, intraocular, retroperitoneal, intraarticular or pericardial, or intramuscular with compartment syndrome, and/or; 3) Bleeding causing a fall in hemoglobin level of 20 g/L (2.0 g/dL) (1.24 mmol/L) or more, or leading to transfusion of two or more units of whole blood or red cells. CRNMB is defined as any sign or symptom of hemorrhage that does not fit the criteria for the ISTH definition of major bleeding but does meet at least one of the following criteria: 1) Requiring medical intervention by a healthcare professional; 2) Leading to hospitalization or increased level of care; 3) Prompting a face-to-face evaluation. n/100 person-years: number of subjects with incident events divided by the cumulative at-risk time in the reference population, where a subject is no longer at risk once an incident event occurred.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Treatment-emergent Adverse Events (TEAEs) During the Main Treatment Period and Within the On-treatment Time Window and Their SeverityUp to 24 weeks

TEAEs were analyzed during the on-treatment time window within the main treatment period in the safety analysis set (SAF). Data observed from the randomization date until the end of the main treatment period. TEAEs were defined as events occurring after first study intervention administration and up to 20 weeks after last study intervention administration.

Maximum Change in FXI Activity Levels During the Main Treatment PeriodBaseline, Days 1 (Pre-Dose and 5 hours post-dose), 2, 8, 15, 22, 29 (Pre-dose and 5 hours post-dose), 43, 57 (Pre-dose), 71, 85 (Pre-dose), 113 (Pre-dose), 141 (Pre-dose),148, 155, 162, and 169 (Pre-dose)

The FXIa activity was measured by a fluorogenic activated FXIa activity (AXIA) assay. Absolute change from baseline at each visit until Visit 22 (Day 169) are reported.

Incidence of Composite of MB and CRNMB During the Main and Extended Treatment Periods and Within the On-treatment Time Window, as Assessed by Blinded CIACUp to 48 weeks

MB is defined as symptomatic bleeding and: 1) Fatal bleeding, and/or; 2) Bleeding in a critical area or organ, such as intracranial, intraspinal, intraocular, retroperitoneal, intraarticular or pericardial, or intramuscular with compartment syndrome, and/or; 3) Bleeding causing a fall in hemoglobin level of 20 g/L (2.0 g/dL) (1.24 mmol/L) or more, or leading to transfusion of two or more units of whole blood or red cells. CRNMB is defined as any sign or symptom of hemorrhage that does not fit the criteria for the ISTH definition of major bleeding but does meet at least one of the following criteria: 1) Requiring medical intervention by a healthcare professional; 2) Leading to hospitalization or increased level of care; 3) Prompting a face-to-face evaluation. n/100 person-years: number of subjects with incident events divided by the cumulative at-risk time in the reference population, where a subject is no longer at risk once an incident event occurred.

Number of Participants With TEAEs During the Main and Extended Treatment Periods and Until 20 Weeks After the Last Study Intervention Dose and Their SeverityUp to 48 weeks

TEAEs occurring from first study intervention intake until 20 weeks after last study intervention intake.

Number of Participants With TEAEs During the Main and Extended Treatment Periods and Within the On-treatment Time Window and Their SeverityUp to 48 weeks

TEAEs were analyzed during during main and extended treatment periods in the safety analysis set (SAF). Data observed from the randomization date until the end of the extension treatment period. TEAEs were defined as events occurring after first study intervention administration and up to 20 weeks after last study intervention administration.

Trough Concentrations (Ctrough) of Three Dose Levels of FesomersenAt visits V12 (Day 57), V14 (Day 85), V16 (Day 113), V18 (Day 141)

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.

Maximum Change in FXI (Coagulation Factor XI) Antigen Levels During the Main Treatment PeriodUp to 24 weeks

The secondary endpoint of change in FXI antigen levels during the main treatment period was an optional secondary endpoint only as mentioned in the integrated clinical protocol amendment version 3.0 and was not analyzed in this study as the FXI activity assay is sufficient to describe the effect on FXI level in plasma.
