- W4315754389 abstract "Vericiguat is indicated for the treatment of symptomatic chronic heart failure in adult patients with reduced ejection fraction who are stabilized after a recent decompensation event. To investigate the effects of vericiguat on QT interval in patients with chronic coronary syndromes (CCS). This was a randomized, phase Ib, placebo-controlled, double-blind, double-dummy, multicenter study. Vericiguat once daily was up-titrated from 2.5 mg to 5 mg and then to 10 mg (treatments A, B, and C) at 14-day intervals. Positive control was moxifloxacin 400 mg (single dose on day 8 or day 50; placebo on other days [treatment D]). We evaluated the placebo-adjusted change from baseline of the Frederica-corrected QTc interval (QTcF), pharmacokinetics, safety, and tolerability of vericiguat. In total, 74 patients with CCS, with mean (standard deviation) age 63.4 (8.0) years, were included and 72 patients completed the study. At each timepoint up to 7 h after administration, mean placebo-corrected change in QTcF from baseline was < 6 ms and the upper limit of the two-sided 90% confidence interval of the mean was below the 10-ms threshold for clinical relevance. Moxifloxacin confirmed the assay sensitivity. Median time of maximum concentration of vericiguat was 4.5 h post-dose. The adverse event profile of vericiguat was consistent with its mechanism of action, and the findings did not indicate any safety concerns. As part of an integrative risk assessment, this study demonstrated no clinically relevant corrected QT prolongation with vericiguat 10 mg once daily at steady state. ClinicalTrials.gov number, NCT03504982. Vericiguat is approved for treating worsening heart failure with reduced ejection fraction. As part of the safety evaluation of vericiguat, this study assessed its effect on the QT interval of the electrocardiogram. An electrocardiogram measures electrical activity of the heart. The QT interval is the time from the start of the Q wave to the end of the T wave. A longer than normal QT interval indicates an increased chance for abnormal heart rhythms. Usually, a QT study is conducted at high doses in healthy volunteers. Previous studies indicated that high doses of vericiguat may cause increased changes in blood pressure in healthy volunteers. Therefore, this study was performed in patients at a normal therapeutic dose. Patients with chronic coronary syndromes were enrolled rather than patients with heart failure with reduced ejection fraction, because they have fewer electrocardiogram abnormalities. The starting dose of vericiguat was 2.5 mg once daily, and the dose was increased to 5 mg and then to 10 mg at 14-day intervals. Placebo was tested for comparison and moxifloxacin (400 mg), a drug known to increase the QT interval, was tested to confirm that the study could detect a change in the QT interval. An increase in the QT interval of more than 10 ms was considered clinically relevant. Of 74 patients included, 72 completed the study. At each timepoint (up to 7 h after dosing), the difference between the QT change for vericiguat and placebo was less than 10 ms; therefore, vericiguat does not prolong the QT interval to a clinically relevant extent." @default.
