Filter by:The primary objective of this study is to determine the effect of ketoconazole on the blood concentrations of darexaban and its metabolites (drug degradation products). The secondary objective of the study is to evaluate the safety and tolerability of a single dose of darexaban alone and when administered together with ketoconazole.
The investigators investigate the effect of Chungkookjang on histamine-induced skin reaction in a double-blind, randomized, placebo-controlled, human trial
The objectives of this study are to assess the safety and effectiveness of the SENSIMED Triggerfish® (TF) device in continuous recording of relative fluctuation in intraocular pressure (IOP). Safety will be assessed by recording of AEs during the 24 hours of continuous TF recording. TF efficacy will be evaluated by demonstrating TF ability to detect: 1. The known phenomenon of increase in IOP when moving from waking state to going to bed, as reflected in pneumotonometer measurements 2. Ocular Pulse frequency relative to direct measurement of Heart Rate (HR). A screening visit and one 24-hour IOP fluctuation recording session are planned for each patient. IOP fluctuation recording sessions will be carried out in a sleep unit. An ophthalmological examination of the eyes will be done at screening and prior to and following the device recording.
The objective of the study is to explore safety and tolerability of single ascending doses of ASP015K, establish the maximum tolerated dose, and determine the pharmacokinetics and pharmacodynamics in healthy volunteers.
Red yeast rice capsule (LipoCol Forte)is a nature product that has been demonstrated a significant cholesterol lowering effect which might be caused by addictive and/or synergistic effects of lovastatin (monacolin K) with other monacolins and substances in capsules. The usual dose of red yeast rice capsule(LipoCol Forte)for hypercholesterolemia is one capsule twice/day. Gemfibrozil is a fibric acid derivative (fibrate). It can reduce the levels of triglycerides and increase the levels of high-density lipoprotein cholesterol (HDL-C). Patients with mixed lipid disorders may therefore benefit from a combination of a statin and a fibrate. Although the combination of a fibrate and a statin is highly effective,concerns about an increased incidence of myopathy and even rhabdomyolysis have limited the widespread use of such combinations. Such combination therapies are prone to drug-drug interactions, which can lead to altered pharmacokinetic profiles of either drug, an effect observed for many statins in combination with fibrates. However, the drug-drug interactions have not been reported between red yeast rice capsule and gemfibrozil. The objective of the study is to evaluate the effect of gemfibrozil on the plasma concentrations of lovastatin and its active form, lovastatin acid, from red yeast rice capsule in healthy volunteers. In addition, the investigators also measure the plasma concentration of creatine kinase (CK) and co-enzyme Q10 for safety assessment.
This is an open-label, Phase I study. Study treatments will entail a four-way crossover among three single, ascending, subcutaneous doses and one intravenous dose of MNTX in six healthy normal male volunteers. Blood samples will be obtained to determine plasma pharmacokinetics, dose proportionality for subcutaneous doses, and absolute bioavailability versus an intravenous dose.
Dolutegravir (DTG, GSK1349572) is a next-generation integrase inhibitor (INI) currently in phase 3 clinical trials for human immunodeficiency virus (HIV). Fixed-dose combinations (FDCs) have greatly simplified the treatment of patients with HIV. While Atripla (an FDC of tenofovir (TDF), emtricitabine (FTC) and efavirenz (EFV)) has become the preferred first line regimen due in large part to its convenient presentation as a full treatment regimen in a single product, other options are needed. A fixed-dose combination of DTG/abacavir (ABC)/lamivudine (3TC) is one such opportunity. This is a single-center, randomized, open-label, 3-period crossover study in healthy adult subjects to evaluate the single-dose relative bioavailability of two experimental oral DTG 50 mg/ABC 600 mg/3TC 300 mg FDC tablet formulations compared to co-administration of the separate tablet formulations (DTG 50 mg tablet and EPZICOM), with each dose administered in the fasted state. Approximately 18 subjects will be enrolled and randomized to one of 6 different treatment sequences. There will be a screening visit within 30 days prior to the first dose of study drug and a follow up visit within 7-14 days after the last dose. There will be a 7 day washout between doses in each treatment period. The following PK parameters for DTG, ABC and 3TC will be measured: area under the concentration curve from time zero (pre-dose) extrapolated to infinite time (AUC(0-infinity)), Area under the concentration-time curve from time zero (pre-dose) to the time of the last quantifiable concentration (AUC (0-t)), maximum observed concentration (Cmax), lag time before observation of drug concentrations (tlag), time of occurrence of Cmax (tmax), terminal phase half-life (t½), apparent clearance following oral dosing (CL/F) and apparent terminal phase volume of distribution (Vz/F).
This study had an open-label, single-dose design. All subjects received a single dose of 30 mg of intranasal ketorolac. Blood samples for determination of ketorolac plasma levels were obtained pre-dose and at specified time points over 24 hours post-dose. The primary objective of this trial was to compare the pharmacokinetics of intranasal ketorolac between elderly and nonelderly adult subjects. The secondary objective was to evaluate the safety profile of intranasal ketorolac in elderly subjects.
This was a non-randomized, open label study in healthy male and female volunteers. A single intranasal dose of 30 mg ketorolac tromethamine was administered to all subjects on Days 1 and 6; in addition, subjects received a daily intranasal dose of 200 µg fluticasone propionate on Days 2-6. Subjects remained resident in the Clinical Unit from the evening of Day 1 until the morning of Day 2 and from the evening of Day 5 until the morning of Day 7, and made ambulatory visits to the Clinical Unit on the morning of Days 3-5. A post study medical was performed within 7 days of study completion. The objective of this study was to assess the effects of chronic administration of fluticasone propionate on the pharmacokinetics of intranasal ketorolac in healthy male and female subjects.
This study characterizes the pharmacokinetic effect of ASP015K on mycophenolate mofetil in healthy volunteers.
