Filter by:This is a single center, randomized, double-blind, placebo-controlled, single ascending dose study that will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamic effects of single doses of RG7625 in healthy male and female volunteers. The study will employ an interleaved cohort ('leapfrog') design in which dosing is alternated between two cohorts and each individual within a cohort will receive study drug dosing on four occasions - in effect giving a four treatment, four period, four-way crossover for each individual. The minimum duration for each participant is approximately 8 weeks.
The purposes of this study are to determine: - Part A - How quickly your body absorbs, breaks down and gets rid of the different formulations of insulin lispro compared to insulin lispro alone formulation. - The safety of insulin lispro in different formulations and any side effects that might be associated with it. - Part B: - How much insulin lispro from different dose ranges is found in the bloodstream using a test insulin lispro formulation (selected from Part A). - The safety of insulin lispro in different formulations and any side effects that might be associated with it. Participants may only enroll in one part. The study is expected to last up to 10 weeks for each part.
THC and CBD have distinct symptomatic and behavioral effects. In healthy individuals, THC can induce psychotic symptoms and anxiety, and can impair memory. In contrast, CBD has anxiolytic and possibly antipsychotic properties, while not impairing memory and other cognitive functions. Instead, CBD has been shown to have significant neuroprotective effects. In humans, CBD values correlated positively with gray matter concentration in bilateral hippocampus. Recent data from experimental animals and in vitro studies suggest that these distinct effects might be caused by opposing effects on brain cannabinoid receptors. Neuroimaging studies have consistently identified brain activity recorded at prefrontal and medial temporal regions as relevant for episodic memory. Additionally, the abundance of cannabinoid receptors in the hippocampus and the parahippocampal and entorhinal cortices suggests a potential impact of CBD in memory deficits typical in healthy aging. However, the evidence relating cannabinoids to these conditions is relatively recent and has been obtained from either biochemical or pharmacological studies. It might be hypothesized that CBDs could be useful to delay or even arrest the progression of functional and structural neuronal degeneration. The investigators will use an episodic memory paradigm to test the effects of THC, CBD and placebo on memory encoding and retention and the underlying neuronal networks on healthy male subjects.
Aerobic exercise produces increases in cardiorespiratory fitness (CF), which constitute a protective factor for cardiovascular disease and all-cause mortality. Therefore, aerobic exercise is a key strategy to promoting cardiovascular. There is some evidence that aerobic high intensity interval training may lead to greater increases in CF compared with continuous moderate-intensity training. The main objective of this study is to examine the effects of an aerobic high intensity training program versus a continuous moderate intensity training program on CF in men 18 to 44 years.
The primary objective of the study is to determine the potential effects of multiple doses of rifampin and clarithromycin on the single dose pharmacokinetics (PK) of the deflazacort active metabolite (21 desacetyl-DFZ) in healthy adult subjects.
This Phase 1, randomized, double-blind, placebo-controlled study will evaluate the safety, tolerability and pharmacokinetics of two, single intravenous (IV) high doses of MHAA4549A as compared to placebo when administered to healthy volunteers.
An open study evaluating the sensitivity and specificity of a microwave-based device, Medfield Strokefinder MD100, to detect chronic subdural hematoma, by comparing measurements on patients recruited for surgery of chronic subdural hematoma to an age- and gender-matched group of healthy volunteers.
This is a single center, randomized, investigator/subject blind, single ascending dose, placebo-controlled, parallel study that will evaluate the safety, tolerability and pharmacokinetics of RO6926496 in healthy male participants. The dose escalation is adaptive in nature. It is planned to enroll 48 subjects in 6 cohorts. The anticipated total duration of the study is 16 weeks.
Investigate the safety of excessive consumption of plant sterol-enriched fermented dairy product over a 4-week period in Japanese healthy adults
Evacetrapib (study drug) is an investigational drug being developed with the aim to help people at high risk of heart problems in the future. In this study we will be comparing how much of the study drug gets into the blood stream when it is given as a single dose (in tablet form) compared to an intravenous injection (given directly into a vein via a small needle). The study is expected to last at least 15 days for each participant, not including screening. Screening will occur up to 28 days before the study drug is given.
