A Phase I, Open-label, Single-Dose Study to Evaluate the Pharmacokinetics, Safety, and Tolerability of AMG 986 in Healthy Japanese Subjects.

Background And Objective: AMG 986 is a first-in-class, novel apelin receptor small molecule agonist initially developed as a treatment for patients with heart failure (HF). Previously, a first-in-human study of AMG 986 was conducted in healthy and HF subjects; however, AMG 986 was not evaluated in Japanese subjects.

Methods: This was a phase I, open-label, single-dose, single-center study conducted to evaluate the safety and pharmacokinetics (PK) of AMG 986 200 mg and 400 mg in 12 healthy Japanese subjects.

A Phase 1, Open-Label Study to Evaluate the Effect of Food and Concomitant Itraconazole Administration on the Pharmacokinetics of AMG 986 in Healthy Subjects.

This phase 1, open-label study evaluated the effect of food and administration of the cytochrome P450 3A4 and P-glycoprotein inhibitor itraconazole (ITZ) on the pharmacokinetics of AMG 986. In cohort 1, 12 healthy subjects received a single oral dose of AMG 986 200 mg ± food on days 1 and 10. In cohort 2, 15 healthy subjects received oral ITZ 200 mg once daily on days 8 to 15 and a single oral dose of AMG 986 10 mg on days 1 and 11.

Pharmacokinetic Drug-Drug Interaction Study of Omecamtiv Mecarbil With Amiodarone and Digoxin in Healthy Subjects.

Omecamtiv mecarbil (OM), a novel cardiac myosin activator, is being evaluated for the treatment of heart failure with reduced ejection fraction. In vitro studies demonstrate OM as a substrate and inhibitor of P-glycoprotein (P-gp), which can result in drug-drug interactions. Two phase 1, open-label studies assessed the effect of coadministration of OM (50-mg single dose) on the pharmacokinetics of digoxin (0.

Pharmacokinetics, Tolerability, and Safety of Single and Multiple Omecamtiv Mecarbil Doses in Healthy Japanese and Caucasian Subjects.

Background And Objectives: Omecamtiv mecarbil (OM) is a cardiac myosin activator under development for the treatment of heart failure. The pharmacokinetics of single and multiple doses of OM were investigated in healthy Japanese subjects in two clinical studies.

Methods: Study 1 (n = 36) evaluated the bioavailability and pharmacokinetics after intravenous infusion (15 mg/h for 4 h) and an oral modified release (MR) tablet in healthy Japanese and Caucasian subjects using 25 mg single and multiple doses and 50 mg single dose.

Effect of Varying Degrees of Hepatic Impairment on the Pharmacokinetics of Omecamtiv Mecarbil.

Omecamtiv mecarbil (OM) is a novel selective cardiac myosin activator under investigation for the treatment of heart failure with reduced ejection fraction. OM is primarily eliminated via metabolism mediated by multiple cytochrome P450 enzymes. This phase 1 single-dose, multicenter, open-label, nonrandomized study evaluated the pharmacokinetics (PK) of OM and major metabolites M3 and M4, safety, and tolerability following oral administration of a single dose of 25-mg MR tablet in subjects with mild (n = 6) or moderate (n = 6) hepatic impairment (according to Child-Pugh classification) versus subjects with normal hepatic function (n = 6).

A clinical therapeutic protein drug-drug interaction study: coadministration of denosumab and midazolam in postmenopausal women with osteoporosis.

Drug-disease interactions involving therapeutic proteins that target cytokines and potentially impact cytochrome P450 (CYP) enzymes have been of increased interest to drug regulatory agencies and industry sponsors in recent years. This parallel-group open-label study evaluated the effects of the monoclonal antibody denosumab, an inhibitor of the cytokine RANKL, on the pharmacokinetics of the probe CYP3A4 substrate midazolam in postmenopausal women with osteoporosis. The pharmacokinetics of a 2 mg oral dose of midazolam was evaluated on days 1 and 16.

The pharmacokinetics and pharmacodynamics of denosumab in patients with advanced solid tumours and bone metastases: a systematic review.

Aim: The objective of this systematic review was to characterize the pharmacokinetics and pharmacodynamics of denosumab (XGEVA®), a fully human IgG2 monoclonal antibody which binds to receptor activator of nuclear factor kappa-B ligand (RANKL), for the treatment of skeletal-related events (SREs) in patients with advanced cancer and bone metastases.

Methods: A total of 708 patients (116 healthy patients and 592 patients with solid tumours or multiple myeloma and bone metastases) included in seven clinical studies were evaluated for denosumab pharmacokinetics. Denosumab was administered as a single subcutaneous (s.
