Filter by:This study will assess the effect of a different dose of the seasonal flu vaccine 2013-2015 on the immune response to improve the investigators understanding of cellular and humoral immune responses induced. The scope of this study is to determine the profile of cellular activation and antibody production in the ageing immune system following flu immunization. This study will enroll 100 male or female subjects ≥65 year old and 90 transplant recipients. These persons will be deemed to be " at risk " in case of influenza infection and should be vaccinated according to Swiss Federal Office of Public Health. A medical doctor from the CHUV will inform the patients about the present study and ask them whether they would be willing to participate in the study. All subjects will be distributed between the two groups according to a computer-generated randomization sequence. The randomization will be done in blocks to ensure balance across groups. The participants and site staff will not be blinded due to the different administration assignments. Group 1 subjects will receive a single dose and group 2 subjects a double dose of MUTAGRIP® manufactured by Sanofi Pasteur containing A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012. Vaccine immunogenicity and safety will be assessed 1, 2, 4 and 24 weeks after vaccination. Study duration per volunteer is 6 months after vaccination.
The study was designed to investigate whether glucagon like peptide-1 is a mediator of protection of endothelial function induced by remote ischemic conditioning in ischemia-reperfusion
Leucine supplementation could be useful to support muscle anabolism. This study aims to investigate the effects of leucine supplementation on muscle mass and muscle strength in young subjects undergoing resistance training.
The purpose of this study is to evaluate the safety and tolerability of single and multiple orally ascending doses of GDC-0310 administered in healthy participants as 4 parts including Part 1- a single dose (SD) part using a powder-in-capsule (PIC) formulation, Part 2- a multiple dose (MD) part using a PIC formulation, Part 3- a SD part using a solution formulation, and Part 4- a MD part using a solution formulation. Effects of food on pharmacokinetics (PK) will also be explored.
This study is a phase I, randomized, placebo-controlled, double-blind (sponsor unblind), three part study. The primary objective of the study is to characterize the safety, and tolerability of GSK3008356 single dose, 14 daily repeat doses in healthy subjects and 28 daily repeat doses in obese subjects. The study has three parts. Part 1, will be a single and multiple-dose, dose-rising study in healthy subjects. Part 2, will be a 14-day, repeat-dose, dose-rising study in healthy subjects, and part 3 will be a 28-day, repeat-dose study in obese subjects. For Parts 1 and 2, data from prior doses cohorts will be available prior to escalation decisions. Data from Parts 1 and 2 will be available prior to initiation of the three parallel cohorts in Part 3. A dose escalation meeting will be held to review these data and document the decision to proceed as planned or make any alterations in dosing, if indicated. Part 1, Part 2 and Part 3 study will have approximately 88, 24 and 30 subjects, respectively.
Hyperpolarised gas Magnetic resonance imaging (MRI) (Hyperpolorised 3He and 129Xe MRI) provides novel regional functional images of the lungs. Over the past 14 years researchers at Sheffield Teaching Hospitals NHS Foundation Trust and University of Sheffield have been developing and evaluating different MRI techniques to investigate different aspects of the lung function with both Hyperpolorised 3He and more recently 129Xe gas and have tested these new methods in volunteers with healthy and diseased lungs. This proposed study is to further test the sensitivity of MRI pulse sequences with inhaled 129Xe gas in volunteers. This protocol serves to evaluate the sensitivity of pulse sequences for 129Xe magnetic resonance imaging in the lungs and monitoring the transient changes in vital signs during and following the gas inhalation. This includes evaluation of pulse sequences to image xenon in the heart and brain as well as in the lungs of volunteers.
The goal of this study is to determine the impact of the food on the absorption of the ABX464.
The purpose of this study is to compare the pharmacokinetics of DP-R207 (Rosuvastatin 10mg and Ezetimibe 10mg fixed dose combinations) in comparison to each component administered alone in health male volunteers.
This will be a double-blind, randomized, placebo-controlled, single ascending dose study performed in healthy subjects. The study will include up to four escalating dose cohorts with eight (8) subjects in each cohort. In each cohort, eligible subjects will be randomized in a 3:1 ratio to receive single IV administration of 9% trehalose (Treatment Arm 1) or placebo (Treatment Arm 2). All subjects, regardless of their treatment arm assignment, will undergo the same evaluations and will receive the study drug at the clinic. Each subject will continue to be followed for one week post dosing.
The purpose of this study is to assess the impact of sleep deprivation on subjective inspiratory endurance in healthy subjects.
