A Study to Assess the Pharmacokinetics and Pharmacodynamics of JNJ-54452840 in Participants With Heart Failure and Anti-beta1-adrenergic Receptor Autoantibodies

Heart Failure Clinical Trial

Official title: A Randomized, Double-blind, Placebo-controlled Pharmacokinetic and Pharmacodynamic Two Part Cohort Study of JNJ-54452840 in Subjects With Reduced Systolic Function Heart Failure and Elevated Levels of Anti-Beta 1 Adrenergic Receptor Autoantibodies

Status Withdrawn

Clinical Trial Summary

The purpose of this study is to assess the pharmacokinetics (ie, how the body affects the drug) and pharmacodynamics (ie, how the drug affects the body) of JNJ-54452840 in participants with heart failure and anti-beta1-adrenergic receptor autoantibodies. The safety and tolerability of JNJ-54452840 will also be assessed.

Clinical Trial Description

This study will be randomized (the study treatment is assigned by chance), double-blind (neither investigator nor participant knows the treatment received), and placebo-controlled (one of the study treatments is inactive). This study will be conducted in participants with reduced systolic function heart failure (a reduced amount of blood is pumped around the body compared with a normal heart) and elevated levels of anti-beta1-adrenergic receptor autoantibodies (antibodies that may be involved in development, progression, or worsening of heart failure). The study will be conducted in 2 parts; participants will receive single doses of JNJ-54452840 in Part 1 and multiple doses in Part 2. Each part of the study will consist of 3 phases; a screening phase, a double-blind treatment phase, and a follow-up phase. There will be 2 cohorts (groups) of participants in Part 1 of the study. In Part 1 (Cohort A), participants will be randomly assigned to 1 of 4 treatment groups: a single intravenous (medication is injected into a vein) dose of 20 mg JNJ-54452840; a single intravenous dose of 80 mg JNJ-54452840; a single intravenous dose of 160 mg JNJ-54452840; or matching placebo (inactive medication). In Part 1 (Cohort B), participants will be randomly assigned to 1 of 2 treatment groups; a single intravenous dose of less than or equal to 240 mg JNJ-54452840 (as determined by the Data Review Committee after review of Cohort A data) or matching placebo. There will be 4 cohorts of participants in Part 2 of the study; the dose of JNJ-54452840 used in each cohort, initiation of each cohort, and the sequence will be decided by the Data Review Committee. In Part 2 (Cohort C), participants will be randomly assigned to 1 of 2 treatment groups: JNJ-54452840 or matching placebo given intravenously once daily for 3 days. In Part 2 (Cohort D), participants will be randomly assigned to 1 of 2 treatment groups: JNJ-54452840 or matching placebo given intravenously once daily for 5 days. In Part 2 (Cohort E), participants will be randomly assigned to 1 of 2 treatment groups: JNJ-54452840 or matching placebo given intravenously once weekly on Days 1, 8, 15, and 22. In Part 2 (Cohort F), participants will be randomly assigned to 1 or more treatment groups involving regimen(s) as explored in Cohorts C, D, or E. Single doses of JNJ-54452840 will not be greater than 240 mg for any Cohort. The active to placebo randomization ratio for each cohort following Cohort A (ie, Cohorts B, C, D, E, and F) will be determined by the Data Review Committee. Participants will come to the study center each time they receive study medication and will remain at the center for at least two hours following each injection. Blood samples will be drawn at time points during the screening period and treatment period for participants in both Part 1 and Part 2 of the study. Participants will return to the study center after the double-blind treatment phase on Day 29 and then for follow-up visits on Days 57 and 85. Participants in Part 1 or Part 2 will be involved in the study for approximately 112 days. Participant safety will be monitored. The study drug, JNJ-54452480 is being investigated for the treatment of heart failure. ;
