Filter by:The purpose of this study is to assess the pharmacokinetics and safety of multiple oral doses of ABT-450/ritonavir/ABT-267 and ABT-333 when co-administered under non-fasting conditions in healthy Chinese adult participants.
This study will evaluate the relationship between basmisanil plasma concentrations and the occupancy of Gamma-Amino Butyric Acid A (GABAA) receptor subtypes containing an alpha5 (α5) subunit in healthy Japanese volunteers. Each participant will have two post-screening imaging sessions. In the first imaging session, participants will have a baseline Positron Emission Tomography (PET) scan. In the second imaging session, participants will receive a single oral dose of basmisanil, followed by two on-treatment PET scans at about 4 and 10 hours post-dose.
The objective of this study is to evaluate the bioequivalence of a new tablet versus a current tablet of ASP015K under fasting conditions after single oral administration in healthy male subjects.
Randomized, double-blind, placebo-controlled, dose-escalation study in healthy male and female volunteers. Subjects will be randomly assigned to 1 of 7 treatment cohorts (Cohorts 1 - 7) of 8 subjects each, to receive either Q203 or placebo (6 active treatment : 2 placebo) in a fasting state. Dose escalation to the next cohort may be considered when at least 6 out of 8 subjects, in a cohort, completes all procedures and none of the subjects has a clinically significant adverse event (AE) that is being followed, or at the discretion of the PI if no drug-related serious adverse events (SAEs) have occurred. A food effect cohort will be enrolled to test administration of Q203 in a fed state, at 100 mg dose level (this dose level may change based on PK analysis results). Subjects who received 100mg dose in a fasting state will return and receive the second dose, with food. Subjects will be followed up for AEs, SAE or pregnancy for 30 days postdrug administration.
This is a Phase 1, randomized, double-blind, placebo-controlled, single-ascending dose study in healthy volunteers to investigate the safety, tolerability, and pharmacokinetics (PK) of MHAB5553A.
This is a Phase I, open-label, randomized, four-treatment period, four-sequence, single-dose, crossover pharmacokinetic study to determine the bioequivalence of pirfenidone after administration of tablet and capsule dosage forms under both fed and fasted conditions.
In this research project, the investigators addressed if incorporating physical movements with preschoolers will help increase their ability to retain concepts learned in preschool such as letter, sound and number recognition. Movement plays an important role in the brain. Exercise shows many benefits for the brain to help maintain clearer thought, improve memory, and increase activity in the brain, especially the areas involved in memory, attention, and language. The following research includes an eight week study of the implementation of movement breaks with one preschool class, while using another class as a control group. During the two weeks of baseline data, data was collected from every student in both groups on their letter recognition with both upper and lower case, letter sound identification, and number recognition for numbers 0-10. The group that implemented movement breaks had three-five minute scheduled times to stop for movement. Data was collected and compared between the two groups to find differences in their academic performance.
This study will evaluate the amount of drug that reaches the circulation when a subject takes the test (liquid) formulation compared to the reference (capsule) formulation. The study will also examine the effect of a high fat meal on the levels of drug in blood.
This randomized, double-blind, placebo-controlled, ascending-dose, parallel-group study will evaluate the pharmacodynamic effects, pharmacokinetics, safety, and tolerability of one week of RG7625 dosing in healthy male and female volunteers. Each participant will receive a single dose of RG7625 or placebo followed by one week of dosing with the same treatment. Each participant will also receive intradermal administration of 4 recall antigens at Screening and on Day 7 of treatment to assess study drug effects on delayed-type hypersensitivity (DTH).
To understand the cardiovascular reactions of the human body to changing conditions of gravity is an important aim of space science. In this context, cardiac output (CO) is a key value to estimate the human cardiovascular system. The main objective of this experiment is to determine the effects of parabolic flight on intravascular volume, and how these changes modulate the complex haemodynamics induced by the parabolas.
