Filter by:This open label, non-randomized, parallel group study will evaluate [11C]-RO5011232 as radiotracer for brain mGlu5 receptor occupancy and investigate the binding of RO49917523 to human mGlu5 brain receptor at steady-state in healthy volunteers. In Parts I, II and III, positron emission tomography (PET) assessments of specific uptake of the radiotracer and whole body dosimetry will be made after intravenous injection of [11C]-RO5011232. In Part IV, subjects will receive RO4917523 orally daily for 14 days while receiving three single intravenous bolus injections of [11C]-RO5011232. The anticipated time on study treatment is up to 4 weeks.
This is a Phase Ia, randomized, double-blind, placebo-controlled, single ascending dose (SAD) study in male and female healthy volunteers, aged 18-55 years, enrolled at a single study site in Canada.
The purpose of this study is to investigate the effect of food on the time course of PH-797804 concentration in the blood following dosing by oral immediate release tablet formulation.
Diet and nutrition play an essential role in the development and the clinical expression of the most common health problems. Overeating and obesity induce oxidative stress, which has been proposed to be a pathogenic mechanism leading to insulin resistance, type 2 diabetes (T2D) and associated cardiovascular complications. The main objective of the proposed research is to evaluate the beneficial effects of polyphenolic compounds derived from red grape marc extracts on the cascade of events leading from overeating to oxidative stress and insulin resistance. For that, we will study free radicals production, inflammatory markers, adipokines, mitochondrial function, insulin sensitivity and energy substrate utilization in healthy volunteers at risk for insulin resistance and T2D (1st degree relatives of T2D patients with associated overweight). These volunteers will be randomized between a placebo and a polyphenol group for 9 weeks. The demonstration of the beneficial effects of polyphenols will be sensitized by high-fructose feeding for the last 6 days of the protocol.
The purpose of this research study is to understand whether there is any difference in the amount of tasimelteon in the blood in smokers versus non-smokers. Additionally, this study will provide an assessment of the effect, if any, of age and body size on the safety and tolerability profile and the pharmacokinetics of tasimelteon.
This single center, open-label, non-randomized, one-treatment, one-period study will evaluate the metabolic profile and the safety of a single oral radiolabeled dose of dalcetrapib in male healthy volunteers.
This study will be an open-label, non-randomized, absorption, metabolism, and excretion study of [14C]-GDC 0941 administered as an oral dose to 6 healthy male subjects following at least a 10-hour fast from food (not including water).
The purpose of this study is to compare and contrast the effects of the probiotic Saccharomyces boulardii, the antibiotic amoxicillin/clavulanate and the combination on the gut microbiota of healthy volunteers.
This will be an open-label, fixed-sequence, single-center, 2 period study. The study is designed to determine the effect of ketoconazole on the pharmacokinetics of GDC-0980.
Background: - Some transplant recipients have been found to have cells in their uterus that come from the donor. Researchers want to study uterine tissue from three different groups of women: (1) healthy volunteers, (2) people who have had a stem cell transplant, and (3) people with rare diseases or conditions that affect reproduction. These samples will help researchers learn more about the way stem cells work in the reproductive tract. Objectives: - To collect cells from the uterus to study how stem cells work in the reproductive tract. Eligibility: - Women at least 18 years of age. Design: - Participants will be screened with a physical exam and medical history. They will also have blood and urine tests. - Participants will have an endometrial biopsy to collect cells for study. The biopsy visit will take 1 to 2 hours.
