Filter by:Data from the literature and previous in vitro research conducted in the investigators' laboratory (INSERM U413/EA4310, University of Rouen) suggest that adrenal corticosteroid secretion might be controlled by sympathetic nervous system. This neurocrine regulation of corticosteroid secretion involves locally released neuropeptides. Among them, substance P is able to stimulate aldosterone and cortisol production via NK1 receptors. The aim of the present study is to investigate the effects of a NK1 receptor antagonist, aprepitant, on adrenocortical secretions in healthy volunteers. Aprepitant is a drug already available for the treatment of nausea induced by chemotherapy. In the present phase IV trial, plasma aldosterone and cortisol levels will be measured under treatment with aprepitant versus placebo, in both basal conditions and after activation of the adrenocortical function by various stimuli, including upright posture, metoclopramide, and insulin-induced hypoglycaemia. All healthy volunteers will be given the two substances (aprepitant and placebo) in a random order during two one-week periods separated by a 14 day-wash-out. This study should allow to determine the role of substance P in the control of corticosteroid production in normal man.
The purpose of this study is to assess the deposition of budesonide to the lung after inhalation with 5 different devices and to relate the findings to in vitro properties of inhaled budesonide.
The ability to label specific cells and image their natural movements in vivo would allow researchers to investigate the mechanisms of disease progression. In addition, cell-based therapy, especially stem cell therapy, requires non-invasive monitoring of transplanted cells to follow their bio-distribution and biological function. Because of recent interest in stem cell treatment, several methods have been investigated for in vivo cell tracking. The investigators propose to assess whether the magnetic resonance imaging (MRI) contrast agent Endorem (superparamagnetic particles of iron oxide) can be used to label cells for in vivo tracking using MRI. The investigators will use 20 healthy human volunteers to: 1. Assess the feasibility of imaging Endorem-labelled cells in vivo 2. Compare the distribution of Endorem-labelled cells with that of intravenous injection of Endorem
The primary objective is to evaluate the safety, tolerability, and immunogenicity of multiple-dose administration of tezepelumab in healthy adults.
To evaluate the safety and tolerability of PF-03882845 in Healthy Volunteers. To evaluate the pharmacokinetics of PF-03882845 in Healthy Volunteers. To evaluate the pharmacodynamics of PF-03882845 in Healthy Volunteers.
This is a Phase I, single centre, randomised, double-blind, placebo-controlled, parallel group study to assess the safety, tolerability and pharmacokinetics of AZD2423 following single ascending dose administration to healthy Japanese subjects.
Background: - For every CHI research study, patients must fulfill a list of criteria, based primarily on their medical condition. To determine whether a patient meets these eligibility criteria to participate in a research protocol, researchers must perform a series of diagnostic tests and procedures. - These evaluations are designed to evaluate a participant s general medical condition (i.e., blood tests, function of certain organs such as the lungs, heart, liver, or kidneys), and to confirm a diagnosis or ensure that a healthy volunteer is in good condition. They maximize the safety for the patients and healthy volunteers at CHI. Objective: - To determine the eligibility of patients and healthy volunteers for active CHI research protocols. Eligibility: - The procedures included in this protocol will determine eligibility for active CHI research protocols. - Both healthy volunteers and patients will be evaluated. Design: - Required tests and procedures for various research studies may include the following: history and physical examination, blood and urine tests, lung and heart function tests (echocardiogram, electrocardiogram, stress test), imaging studies (X-rays, magnetic resonance imaging (MRI), computerized tomography (CT), and tissue collection. - Participants will be asked to undergo tests only for the study or studies for which they are being considered. The research team will provide further information on any additional tests that may be required. - After all eligibility assessments are complete, participants may be offered participation in one or more CHI research protocols or referred back to a home physician.
The purpose of this study is to determine the single-dose pharmacokinetics of the investigational drug PL 3100 following oral administration to healthy volunteers and to compare the pharmacokinetic profiles of PL 3100 and naproxen at a prescription dose.
The purpose of the study is to evaluate the effect of food intake on the pharmacokinetics of YM178 in healthy, non-elderly adult subjects.
The aim of the study is to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of AZD5423 following single ascending dose administrations in healthy male subjects.
