Pharmacokinetics and Safety of a Single Oral Dose of Mirogabalin in Japanese Subjects With Varying Degrees of Renal Impairment.

ABSTRACT: Mirogabalin (DS-5565) is a novel preferentially selective ?2 ?-1 ligand being developed for the treatment of diabetic peripheral neuropathic pain and postherpetic neuralgia. The current multicenter open-label study determined the effect of varying degrees of renal impairment on the pharmacokinetics and safety of a single dose of mirogabalin 5 mg in Japanese subjects. A total of 30 subjects (6 subjects per renal function category [normal, mild, moderate, or severe impairment; and end-stage renal disease (ESRD)]) were enrolled and completed the study. The AUClast increased with severity of renal impairment; the geometric least-squares mean ratios of AUClast compared with subjects with normal renal function were 1.3, 1.9, 3.6, and 5.3 for patients with mild, moderate, and severe impairment and ESRD, respectively. In accordance with this AUClast increase, apparent total body clearance (CL/F), renal clearance (CLr), and the cumulative percentage of mirogabalin dose excreted into urine all decreased with severity of renal impairment. There were no deaths and no severe treatment-related adverse events (TEAEs), serious TEAEs, or TEAEs resulting in study discontinuation. Mirogabalin was well tolerated in Japanese subjects with normal renal function and those with mild to severe renal impairment. It was also tolerated in subjects with ESRD but with a higher incidence of TEAEs. The most frequently reported TEAEs were dizziness (ESRD, n = 3), somnolence (ESRD, n = 2), and vomiting (ESRD, n = 2). Based on these data, a mirogabalin dose adjustment will be considered in Japanese subjects with moderate to severe renal impairment and those with ESRD.

Project description:Background and objectiveOmecamtiv mecarbil is a novel selective cardiac myosin activator (myotrope) under investigation for the treatment of heart failure with reduced ejection fraction. The objective of this clinical study was to estimate the effect of varying degrees of renal impairment on the pharmacokinetics of omecamtiv mecarbil single dose (50 mg) under fasted conditions.MethodsThis phase I, open-label, non-randomized, parallel-group study evaluated the pharmacokinetics, safety, and tolerability of a single oral dose of omecamtiv mecarbil 50 mg in individuals with normal renal function or mild, moderate, and severe renal impairment, including end-stage renal disease requiring dialysis. Geometric least-squares mean ratios of maximum observed concentration (Cmax) and area under the plasma concentration-time curve (AUC) and 90% confidence intervals were derived for comparisons of renal impairment vs normal renal function. Participants were monitored for adverse events.ResultsThirty-one participants received treatment and completed the study. Geometric mean exposures were similar for participants with renal impairment (AUC∞ range, 2550-3220 h*ng/mL; Cmax range, 78.9-107 ng/mL) and participants with normal renal function (AUC∞, 2790 h*ng/mL; Cmax, 92.6 ng/mL), with geometric least-squares mean ratios of 85.2-125.9. Exposure was similar on dialysis vs non-dialysis days in participants with end-stage renal disease (AUC0-24, 1650 vs 1700 h*ng/mL; Cmax, 100.0 vs 107.0 ng/mL). Four participants (12.9%) reported four treatment-emergent adverse events. No deaths, treatment-emergent adverse events leading to discontinuation, or serious adverse events occurred.ConclusionsOmecamtiv mecarbil pharmacokinetics were not meaningfully affected by renal function or hemodialysis, suggesting the same dosing strategy can be used in individuals with normal renal function or renal impairment. Oral administration of omecamtiv mecarbil was not associated with major tolerability findings. This study supports omecamtiv mecarbil for the treatment of heart failure in individuals with or without renal impairment.
