Filter by:This study will compare two strengths of the new long-acting growth hormone somapacitan. The aim of this study is to test if both strengths are taken up in the blood in the same way. During three separate dosing visits participants will get a total of 3 injections of the study medicine. Somapacitan is not yet approved and therefore cannot be prescribed by a doctor outside of this study. The study duration is between 10 and 15 weeks. Participants will have 17 visits with the study doctor. Three visits will each comprise 6 in-house days with overnight stays. In total, at least 15 overnight stays at the clinic. There will be blood samplings during the study. Participants must come to the clinic regularly for these blood samplings. People who have already received growth hormones in the past or who are growth hormone deficient cannot be in the study. People cannot be in the study if the study doctor thinks that there are risks for their health. Women cannot take part if pregnant, breast-feeding or planning to become pregnant during the study period.
To determine the pharmacokinetic/pharmacodynamic characteristics and safety/tolerability of MT921 in Healthy Subjects
Respiratory failure is characterized by low levels of oxygen and high levels of carbon dioxide in the blood which causes difficulty breathing. The management of patients with respiratory failure aims at improving oxygenation and changing the effort required to breathe. Mechanical ventilation is a life-saving treatment but may be associated with a high mortality rate, prolonged stay in the intensive care unit (ICU), and infection. Oxygenation techniques to avoid mechanical ventilation include standard oxygen therapy, continuous positive pressure (CPAP), and high-flow nasal cannula oxygen therapy (HFNC). CPAP consists of delivering oxygen through a mask. As compared to standard oxygen therapy, CPAP can promote lung recruitment leading to improved oxygenation and the effect in work of breathing in patients with respiratory failure. Conversely, high-flow nasal cannula oxygen therapy (HFNC) delivers oxygen through nasal prongs. Oxygen is heated and humidified and can be delivered at different flows (from 10 - 60 L/min). As compared to standard oxygen therapy, HFNC can promote some lung recruitment leading to mofiy oxygenation and work of breathing. Therefore, the present study will have 2 phases: Phase 1:Comparison of the physiological effects of different flows of HFNC to CPAP in healthy volunteers. The investigators hypothesized that the physiological effects of HFNC in the nasopharynx are comparable to that of CPAP at 4 cm H2O. Phase 2: Comparison of the physiological effects of different nasal interfaces of HFNC (Standard cannula vs. Asymmetrical cannula vs. Single-nostril adapted cannula) in healthy volunteers. The investigators hypothesized that the physiological effects of HFNC in the nasopharynx are comparable to that of CPAP at 4 cm H2O. It was hypothesized that asymmetrical which is the cannula that has a higher cross-sectional area generates higher nasal pharyngeal pressure.
All participants in this study are healthy volunteers. Throughout the study, healthy volunteers will have physical exams, electrocardiograms and clinical laboratory tests. The study staff will keep track of symptoms, diet, and what medications they are taking. Each participant will get all three treatments (A, B and C). Only the order in which they receive them will be different. There are six groups based on the order: ABC, ACB, BAC, BCA, CAB, or CBA. Participants have an equal chance of being assigned to any of these groups. For each treatment period, participants will: - fast overnight - receive the assigned treatment with or without food - have a small tube of blood drawn prior to treatment - after dosing, additional blood samples will be drawn at 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 14, 22, 24, 28, 32, 36, 48, 54, 60, 72, 84, 96, 108, 120, 132, and 144 hours - have a break from treatment for 6 days between each treatment period All participants must reside in the clinic for a total of 20 days.
The primary objectives of this study were: - To assess the effect of a high-fat diet on the pharmacokinetics (PK) of a 0.75 mg single dose of S-888711 orally administered as 0.25 mg tablets in healthy volunteer adults - To assess the effect of a calcium supplement on the PK of a 0.75 mg single dose of S-888711 orally administered as 0.25 mg tablets in healthy volunteer adults
Chronic corticosteroid (CS) exposure is associated with changes in memory and the hippocampus in both humans and in animal models. The hippocampus has a high concentration of glucocorticoid receptors (GCRs), and the pre-clinical literature demonstrates shortening of apical dendrites in the CA3 region of the hippocampus and decreased neurogenesis in the dentate gyrus (DG) following CS administration. In humans, both stress and CS exposure are associated with a decline in declarative memory performance (a process mediated by the hippocampus). Impairment in declarative memory and hippocampal atrophy are reported in patients with excessive CS release due to Cushing's disease, and, by our group, in patients receiving prescription CS therapy. These findings have important implications for patients with mood disorders, as a large subset of people with major depressive disorder (MDD) show evidence of HPA axis activation, elevated cortisol and, importantly, resistance to the effects of CSs on both the HPA axis and on declarative memory. Thus, resistance to corticosteroids appears to be a consequence of MDD. this study will examine changes in declarative memory, as well as use state-of-the-art high-resolution multimodal neuroimaging, including structural and functional (i.e., task-based and resting state) MRI, in both men and women healthy controls, and, as an exploratory aim, a depressed group, given 3-day exposures to hydrocortisone (160 mg/day) or placebo. The study will translate preclinical findings to humans, provide valuable data on possible sex differences in the response to cortisol and, for the first time, identify specific hippocampal subfields (e.g., CA3/DG) in humans that are most sensitive to acute CS effects. Using resting state fMRI data and whole brain connectomics using graph theoretical approaches, we will determine the effects of cortisol exposure on functional brain networks. Furthermore, this will be the first study to use neuroimaging to compare the brain's response to CSs in people with depression vs. controls, and determine whether depressed people demonstrate glucocorticoid resistance within the hippocampus. We hypothesize that hippocampal response to acute CSs will be greatest in the CA3/DG subfield, greater in women than in men, and that depressed people will show a blunted hippocampal response to CSs compared to controls. A multidisciplinary research team with extensive experience in CS effects on the brain and hippocampal subfield neuroimaging, and a prior history of research collaboration, will conduct the project.
Background: The HIV research program is part of the National Institute of Allergy and Infectious Diseases. The program aims to learn more about HIV. It also aims to improve the health of people with HIV and create HIV vaccines. People enrolled in prior HIV studies provided samples or data. They consented for their samples or data to be used for future research. Researchers want to keep studying the stored samples and data. Objective: To give approved researchers access to stored samples and data after the study of sample origin is over. To do this with human subjects protection oversight by the NIH institutional review board (IRB). Eligibility: The study populations were defined by the protocols under which the samples or data were obtained: 11-I-0259, 13-I-0081, and 14-I-0011. Design: All participants consented to provide blood or other samples. Their consent included future use of the samples. Researchers will not contact participants without prior approval of the IRB or the original study protocol. Samples will be labeled with a code. They will not be labeled with information that identifies the participants. Participants data will be stored in computers. The computers will be protected with passwords. This protocol will be kept open as long as the samples or data can be used for future research. When there is no longer a need, the samples may be moved if the IRB approves this. Otherwise they will be destroyed. ...
