The primary purpose of this study is to evaluate the effect of single and multiple doses of JNJ-64155806 on the steady-state pharmacokinetics (PK) of ethinylestradiol and drospirenone and vice versa in healthy female participants.
The study aimed to understand how payoffs for others influence perceptual decision making. The research consists in testing how varying monetary payoffs for another modify the perceptual decision making processes. The use of drift diffusion models on a random dots task enable the characterization of the decision parameter(s) that are modulated when a decision is made to win payoffs for others as compared to decisions for self-benefits. Once the parameter revealed through behavioral experiment, neuroimaging is applied to find the neural correlates of the effects of taking others into account in the decision making process.
Functional Magnetic resonance study on the effect of cognitive context variables on the perception and valuation of food odorants and flavor. The study is composed of two experiments; in a first experiment we address the question of how valuation of food odors are modulated by 3 cognitive conditions (indulgence, healthy, and neutral). Food odors are delivered using a custom-made olfactometer. Here we hypothesize that cognitive regulation can modulate the primary sensory processing of food odors. We expect that cortical regions related with valuation and cognitive regulation such as the ventromedial prefrontal cortex and the dorsolateral prefrontal cortex operate the modulation of primary olfactory cortex and amygdala. In a second experiment, we aim to reveal the brain areas involved in integrating food color cues with odor and taste stimuli. Here we hypothesize that color cues are capable of biasing flavor attributes of food (flavor intensity), and that this bias occurs at different cortical areas commonly associate with multisensory integration such as the orbitofrontal cortex, insula, amygdala and hippocampus.
The purpose of this study is to investigate neural mechanism of healthy humans underlying group decision making and compare it with that of individual decision-making. Using functional neuroimaging technology combining with computational modeling, we examine how the human brain process social information to make a decision within a group, which often guides humans to make a better decision using collective wisdom.
Safety, Tolerability and Pharmacokinetics of PF-06818883
The purpose of the study is to assess the oral bioavailability of the two tablet formulations of JNJ-54416076 relative to the suspension formulation and to investigate the effect of a high fat meal on the pharmacokinetics of the tablet formulation in healthy participants.
The purpose of this study is to assess the safety, tolerability and pharmacokinetics (PK) of multiple oral doses of GMC-252-L-Lysine salt (GMC-252) in healthy subjects and type 2 diabetics. The secondary objective is to explore the effect of multiple oral doses of GMC-252 on pharmacodynamic(PD) parameters in type 2 diabetics.
This Phase 1 study will be a double blind, third party open (ie, subject blind, investigator blind and Sponsor open), randomized, placebo controlled, single and multiple dose escalation study in healthy subjects, females of non childbearing potential and males between the ages of 18 and 55 years, inclusive. There may be up to 11 Cohorts in the study. Approximately 7 cohorts are anticipated in the Single Dose (SD) portion of the study and up to 4 cohorts are anticipated in the Multiple Dose (MD) portion of the study. Following the last subject Day 28 visit from the first two single dose cohorts (Cohorts 1 and 2), all available data inclusive of Day 28 will be evaluated for PK, immunogenicity, safety and tolerability. FDA review and agreement to move forward will take place before the remaining single dose cohorts and the multiple dose phase (Cohorts 3 to 11) can be initiated. A total of up to approximately 82 subjects are anticipated to be enrolled in the study. The duration of dosing in the multiple dose cohorts would be 4 weeks and the regimen may include weekly (total of 5 doses), every 2 weeks (total of 3 doses) or monthly dosing (total of two doses).
The purpose of this study is to determine the toxicity, tolerability and safety of single ascending doses of GMC-252-L-Lysine Salt in healthy male subjects.
This is a Phase 1, open-label, single-dose, randomized, dose escalation study in healthy and hypercholesterolemic subjects. Each subject will receive 1 of 5 treatments as a single subcutaneous injection. Subjects will remain confined at the research clinic for approximately 2 days. After discharge, subjects will return to the research clinic 15 times during 12 weeks.
