Filter by:This is a dual-centre, Phase I/IIa study, in healthy subjects and subjects with AD to investigate the safety, tolerability, cognitive, and behavioural effects of RPh201. The study will be divided into three parts: A, B, and C (NOT Performed)
This will be a phase 1 randomized, double-blind crossover trial enrolling approximately 12 healthy volunteers to assess whether intravenous (IV) UFH and IV Bendavia administered together have any significant impact on the pharmacodynamic effects of UFH and the pharmacokinetics of Bendavia.
This open-label, single-dose, parallel-group study will investigate the pharmacokinetics and safety of RO4917838 in healthy and renal impaired subjects. Subjects will receive a single dose of RO4917838.
This is a randomized, double-blind, placebo-controlled, single ascending dose study to assess the safety and tolerability of Intravenous (IV) and Subcutaneous (SC) REGN1033(SAR391786) in healthy volunteers.
Vaccines for human papillomavirus (HPV) have been available in the United States since 2006. Early studies have shown a high rate of effectiveness of these vaccines, however it is not known how long this protection will last. The IMAP study will look at various parts of the immune system and potential markers for long lived immune responses to this vaccine.
Approximately 66 million informal caregivers care for someone who is ill, disabled, or aged. These caregivers experience significant distress associated with caregiving, which may be particularly salient in the context of inherited conditions. Previous studies have not examined caregiving from a network perspective, nor have they considered how cognitive and emotional responses, such as caregivers worry for themselves and relatives acquiring the disease or guilt related to the genetic etiology of their child s illness, as possible stressors; the current project fills this literature gap. Caregiving processes may vary across type of illness and the life course. In illnesses that impact children, parents and grandparents may take on caregiving roles whereas in conditions that impact adults, spouses and adult children may provide care. Caregivers must adapt to the strain of caring for their affected relatives and this adaptation may differ depending on caregiver roles. The caregiver s support network may influence adaptation, impacting the health and well-being of patients, their caregivers, and other relatives. This project, comprised of 5 substudies, will examine social contexts surrounding families involved in caring for individuals with chronic inherited conditions from a relational perspective. Surveys and interviews will assess participants cognitions and emotions about the disease, caregiving burden and caregiving/support network systems. In addition, biomarkers will be considered in 2 substudies to examine how caregiving roles and expectations impact health among caregivers. As part of our current inquiry, we have developed an assessment tool aimed at understanding caregiver experiences related to dietary practices in the context of metabolic conditions. To evaluate the psychometric properties of this scale, we propose a fifth substudy under the current protocol. We aim to recruit at least 5550 participants through residential/daycare centers, advocacy groups, and the NIH Clinical Center. We will recruit formal caregivers, multiple biological and non-biological adult relatives of affected individuals and typically developing controls to construct and evaluate caregiving/support network systems. This project will use a social network framework to develop and adapt common measures of caregiving roles to evaluate burden, perceptual bias, and unmet expectations in caregiving. The psychometric properties of these new measures, characteristics of family caregiving and support networks, and how these network characteristics are associated with caregiving strain and well-being, including biomarkers of physical health, will be investigated. The moderating role of family members cognitions and emotions and disease context will be considered. Findings will guide future research to develop network-based interventions promoting positive adaptation to the presence of inherited conditions in families through improved social environments and coping skills....
The overall clinical trial objective is to gain information about the Pharmacokinetics (PK) of a 400 µg dose strength of INFS using a Population PK (PopPK). In total, 20 healthy male and female subjects are planned to be randomized in the trial. Subjects will be randomized to one of two treatment sequences and treated with 3 different dosages (either 200 µg/dose INFS, 400 µg/dose or 400 µg two doses administered 10 minutes apart) over two days. Subjects will be hospitalized over a period of total 5 days, where safety assessments and pharmacokinetic samplings will be conducted.
Antihistamines are commonly used and currently levocetirizine is most frequently prescribed in the Netherlands. They are commonly used by divers, to solve ear, nose and throat problems, especially to open tubal passage. However, the effects of these drugs on cognitive performance have not been investigated during diving.The objective of this study is to investigate the effects of levocetirizine, hydroxyzine and placebo on cognitive and psychomotor functioning during controlled simulated diving in a hyperbaric chamber in professional navy divers at 10 mt (2 bar) and 30 mt (4 bar).It is hypothesized that hydroxyzine will produce significant impairment, and that the magnitude of impairment is related to hyperbaric pressure.
This randomized, double-blind, placebo-controlled study will evaluate the safety and pharmacokinetics of RG7667 in healthy volunteers. Subjects will be randomized in cohorts to receive either single/multiple doses of RG7667 intravenously or placebo. Anticipated time on study treatment is up to 57 days with a 12-week follow-up.
This open-label, fixed-sequence, two-period study will assess the effect of multiple dose valproate on the pharmacokinetics of RO4917838 at steady state and vice versa in healthy male volunteers. In Period 1, subjects will receive valproate for 5 days. After a washout period of 5 days to 2 weeks, subjects will receive, in Period 2, RO4917838 for 15 days with concomitant valproate on Days 11-15. Anticipated time on study is up to 12 weeks.
