Filter by:The purpose of this study is to evaluate the tolerability, safety, pharmacokinetics (PK, or amount of drug over time in the body) and pharmacodynamics (PD, or effects on the body) of ACT-541468 following multiple ascending doses in healthy adults and following single ascending doses in healthy elderly subjects when administered in the morning. The safety, PK and PD of ACT-541468 will also be assessed after repeated evening administration of a selected dose in both healthy adults and elderly.
Oral dosage regimens for fosfomycin tromethamine (Monurol™) are not established for the treatment of cUTI. The most common and recommended adult dosage regimen in the literature is a single-dose sachet containing the equivalent of 3 grams of fosfomycin administered every other day (QOD) for a total of three doses. There are a myriad of different oral fosfomycin dosing regimens currently being used in clinical practice, including up to 3 grams orally twice daily for 7-21 days, but these regimens are not based on solid pharmacokinetic, pharmacodynamic or safety rationale. Initial pharmacokinetic studies performed with oral fosfomycin tromethamine primarily examined single dose regimens and did not use modern day bioanalytical or pharmacokinetic techniques. As the use of fosfomycin becomes more pervasive in concordance with the increase in multidrug resistant pathogens, further pharmacokinetic and safety data are needed for more intensive dosing regimens to support its continued use. The rationale of this study is that oral fosfomycin tromethamine requires a modern pharmacokinetic-pharmacodynamic study to identify alternative oral dosage regimens that are appropriate and safe. This study provided safety/tolerability and clinical pharmacology information regarding two oral dosing regimens that may have application to treat various types of infections involving resistant pathogens or when other oral antibacterial options are not available.
The purpose of this study is to compare the efficiency of nebulization and positive expiratory pressure combination
The purpose of this study is to establish if BMS-986165 is safe and effective at treating autoimmune diseases. BMS-986165 which has shown some promise in preclinical studies for inhibiting autoimmune conditions. This study will be the first time this drug is given to humans, and will be conducted entirely in healthy subjects. It will be run in 4 Parts. Part A will investigate single oral doses of drug. Part B will investigate giving the drug daily for 14 days. Part C will investigate daily doses for 14 days in healthy volunteers with Japanese decent. Part D will investigate whether food, stomach acidity or giving the drug in a capsule makes a difference to the safety and potential use of this drug.
This study is designed to first evaluate the effect of food on E7050's pharmacokinetic parameters following the administration of single 100 mg oral doses of E7050 tablet to each normal healthy participant in the study (Part A), and second to characterize E7050 pharmacokinetics after single doses at 200 mg and 400 mg under fasted conditions (Part B). Part A will be a randomized, single-dose, open-label, three-treatment period crossover study. Part B is a nonrandomized, open-label, two-treatment sequential study design. Twelve participants in Treatment Period 1 will receive a single dose of 200 mg of E7050 under fasted conditions. Following review of safety data of the 200 mg dose level, an additional 12 subjects will then receive a single dose of 400 mg of E7050 in Treatment Period 2.
This is a Phase I, Randomized, Single-Blind, Crossover Study to Assess the Pharmacodynamics of AZD9977 following Single-Dose administration to healthy male subjects
In this study the investigators plan to systematically characterise infra-slow EEG oscillations during sleep, explore their relationship to the microstructure of sleep, and investigate its role in the physiology and pathophysiology of sleep by co-registration of Full band EEG with polysomnography during wake and sleep in healthy subjects, after sleep deprivation, and in patients with restless legs syndrome/periodic leg movements during sleep (RLS/PLMS).
The main objective of this study is to investigate whether repeated administration of a cardiac medication (diltiazem) can affect the pharmacokinetics (i.e., amount and time of presence in the blood) of ACT-541468
To date two different instruments are commercially available to measure retinal oxygen saturation and retinal vessel diameters: Dynamic Vessel Analyzer (DVA) and Oxymap. Retinal oxygen saturation analysis is based on spectroscopic evaluation of retinal fundus images. Up to now no data comparing both instruments for the measurement of retinal oxygen saturation and vessel diameter are available in the literature. Study objectives: To compare retinal oxygenation and retinal vessel diameters in healthy subjects and patients with diabetic retinopathy or retinal vein occlusion between 2 commercially available systems (DVA, Oxymap T1) Study design: Open pilot study Study population: 30 healthy volunteers, age 18-80 years 30 type 2 diabetic patients with mild or moderate non-proliferative diabetic retinopathy, age 18-80 years 30 patients with retinal vein occlusion, age 18-80 years Topically administered medication: Tropicamide (Mydriaticum "Agepha"®, Agepha, Vienna, Austria), dose: 1-2 drops per study day for dilation of the pupil Oxybuprocainhydrochloride combined with sodium fluorescein (Thilorbin®, Alcon Pharma GmbH, Freiburg, Germany), dose: 1 drop in one eye for measurements of intraocular pressure Nonylacidvanillylamide combined with Nicotinic-acid--ß-butoxyethylester (Finalgon®, Boehringer Ingelheim RCV GmbH & Co KG, Vienna, Austria): topical on the earlobe Methods: Dynamic vessel analyzer Oxymap T1 Blood pressure and pulse rate measurement Applanation tonometry Oxygen and carbon dioxide partial pressure measurement in arterialized blood from earlobe Main outcome variables: Difference of oxygen saturation of retinal vessels between DVA and Oxymap T1 The motive for this investigation is to compare data between 2 commercially available instruments for the measurement of retinal oxygen saturation and retinal vessel diameter in healthy subjects as well as in patients with ocular disease associated with altered retinal oxygenation. Comparative data from both systems are currently not available. Data from this study will allow the comparison of studies performed with different systems. All oxygen measurement procedures are non-invasive and painless. Hence, the risk/benefit ratio appears to be acceptable.
This is a Phase I, first-in-human (FIH), randomized, single-blind, placebo-controlled, single ascending dose sequential group study in healthy male subjects. The objectives are to study the safety, tolerability, pharmacokinetics and effects on glucose homeostasis (pharmacodynamics) of AZD9567, an oral differentiated non-steroidal selective glucocorticoid receptor modulator (SGRM). The study will also assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of prednisolone 60 mg in comparison with high doses of AZD9567 and placebo.
