The safety, tolerability and movement of the BMS-986205 into, through and out of the body (pharmacokinetics/PK) under these conditions will be assessed.
Objective: To screen and create a list of adult volunteers in good health for participation in research studies conducted at the National Institutes of Health (NIH) in Bethesda, Maryland. Develop a normative set of structural and functional brain MRI scans that are linked to healthy research volunteer characteristics. Maximize scientific impact of data from volunteers by broadly sharing with other researchers. Study Population: Adult males and females in general good health who are 18 years of age and older. Design: Adult individuals who are interested in participating in NIMH IRP clinical studies as a healthy research volunteer can directly visit or be directed to visit the study website where they will first consent electronically and then complete a set of online self-report measures. Items may include: demographic information, mental health symptoms, disability status, substance use patterns, handedness and clinical/family history. Individuals who are flagged based on predetermined responses to survey items will be further screened by a member of the study clinical team. If found to be ineligible for the study because of a clinically significant or unstable medical or mental health condition, these individuals will be referred back to the community and/or given information about NIMH clinical studies for which they may be eligible. Respondents with no flags or who pass through additional screening will be scheduled for an in-person assessment. During the outpatient appointment and after in-person informed consent, participants will receive a brief clinical interview to screen for current medical and mental conditions, and risk for self-harm. They will complete assessments of psychological, emotional, physiologic, biological and cognitive functioning. Participants will undergo a physical exam and be asked to provide blood and urine samples for routine clinical labs as well as additional blood samples for future secondary analysis that could include genetic or biomarker assays. Participants can separately consent for an optional baseline brain magnetic resonance imaging (MRI) scan and an optional magnetoencephalography (MEG) exam. All consent forms will explicitly inform participants that if enrolled in the study, their de-identified data will be broadly and publicly shared through NIH-approved data repositories. Participants in this recruitment and characterization study will then be placed on a list of healthy research volunteers from which other NIMH IRP studies may recruit according to the inclusion and exclusion criteria in their respective IRB-approved protocols. Outcome Measures: Outcome measures may include demographic data, mental and medical history and symptoms, results of psychological, emotional, physiologic, biological, and cognitive testing, physical exam and MRI findings. ...
The purpose of this study is to evaluate the pharmacokinetics and bioequivalence of Ritonavir tablet 100 mg versus NORVIR 100 mg tablet in healthy Chinese adult participants under fasting or fed condition.
Phase 1 study in healthy subjects to determine the effect of rifampin (Part A) or itraconazole (Part B) on the pharmacokinetics of BGB-3111
High-intensity interval training (HIIT) is currently considered one of the most effective strategies to improved cardiorespiratory fitness, which is recognized as a protective factor for cardiovascular diseases and metabolic diseases such as overweight and obesity. However, current evidence is still limited and requires clarity (frequency, time per session and intensity) regarding to greater increases attributed to HIIT. The aim of this study is to compare the effect of a low-volume high-intensity interval training versus a moderate-intensity continuous exercise on maximal oxygen consumption in overweight women 18 to 44 years old.
Although most ground studies showed that an egocentric reference frame better supports spatial orientation, it is not proven it will be the same during weightlessness. Although it might justify that visuomotor performance will be better supported by egocentric target cueing under altered gravity conditions, the fact that exocentric target cueing induces less head movements and called for least attentional and physiological workload could be the key factors for a more efficient task localization process. Moreover, weightlessness can induce spatial disorientation, which can be additionally influenced by the intrinsic and extrinsic spatial reference frames (Gurfinkel et al., 1993; Glasauer & Mittelstädt, 1997, 1998; Harm et al., 1998; Lipshits et al. 2005). We expect that during weightlessness the workload will be the key factor and thus we hypothesize that an exocentric target cueing will outperform egocentric target cueing. To test this hypothesis, and find out which presentation scheme for target cueing (EGO, EXO, ED) contributes most to an efficient visual search, performance to a visuomotor task will be evaluated during parabolic flights in normogravity (1g), hypergravity (1.8g) and microgravity (0g). The visuomotor performance will be assessed by a multi-directional tapping task as defined by ISO9241-9, which requests for motor responses by aimed pointing movements. Besides analyzing the pointing performance, different workload indices will be additionally assessed to evaluate the effort spent on visuomotor coordination. The attentional workload will be evaluated by the performance of a secondary task (visual reaction-time task), which needs to be conducted in parallel to the visuomotor task. Furthermore, the workload will be also assessed subjectively by the NASA TLX rating scale and physiologically, by analyzing the heart rate variability (HRV).
The purpose of this study is to evaluate the effect of varying degrees of renal function on the PK of TAK-954 following single-dose IV administration and to investigate the impact of hemodialysis on the PK of single IV doses of TAK-954.
This is a single-center, open-label study to characterize the biotransformation and excretion of [14C]-CC-220 in healthy male subjects. Each subject will participate in screening, a treatment phase (including baseline), and a follow-up phone call. Subjects will be screened for eligibility. Subjects who have met all inclusion criteria and none of the exclusion criteria at screening will return to the study site on Day -1, and will be domiciled at the study site from Day -1 to Day 10. On Day 1, subjects will receive a single oral dose of 1 mg [14C]-CC-220 under fasted conditions. Blood, urine, and fecal samples will be collected throughout the study for pharmacokinetic (PK; inclusive of metabolite profiling / characterization), mass balance, and/or clinical laboratory assessments. Safety will be monitored throughout the study. Subjects will be discharged from the study site on Day 10 following completion of the scheduled study procedures and satisfactory safety review. Subjects will participate in a follow-up phone call within 5 to 7 days following discharge.
Randomized, double blind, parallel group, single dose, 3 arm study to investigate and compare the Pharmacokinetics (PK), safety and immunogenicity profile of MB02 with US and EU Avastin® in healthy male subjects. During the course of the study, the similarity in pharmacokinetics will be assessed by sampling the levels of drug in the blood, and by comparing these levels among the different administration arms. Safety, tolerability, and immunologic response to the administered drugs will also be evaluated throughout.
Previous work has shown that gelatin supplementation could increase collagen synthesis in humans. In this study subjects consume placebo, 5 or 15 g of gelatin with a standard amount of vitamin C (48 mg) 1 hour before 6 minutes of jump rope exercise. The feeding and exercise intervention was repeated every 6 hours while the subjects were awake for three days and the amount of the amino terminal procollagen I peptide (PINP) was determined; a marker of collagen synthesis, in the blood. Consistent with the hypothesis that gelatin increases collagen synthesis in humans; the amount of PINP in the 15 g gelatin group was significantly higher than either the placebo or the 5 g groups. These data conclusively demonstrate that gelatin supplementation can increase exercise-induced collagen synthesis in humans. Hydrolyzed collagen has a similar amino acid profile, in particular with high concentrations of glycine, proline, hydroxyproline, and arginine. Thus the current study aims to precisely map out the dose response relationship of hydrolyzed collagen and vitamin C on PINP and to determine the optimal dose to achieve maximal increased in PINP levels.
