Filter by:This study was a Phase 1, double-blind, placebo-controlled, randomised study of very low dose LSD. Healthy volunteers aged 55 to 75 years with no use of LSD in the past 5 years were screened within 28 days of randomization. Subjects who met all inclusion and no exclusion criteria and provided written informed consent were randomised a 1:1:1:1 ratio to receive 6 doses of 5 µg, 10 µg, or 20 µg LSD or placebo, at 4-day intervals for 21 days (on Study Days 1, 5, 9, 13, 17, and 21). A follow-up visit was conducted approximately 4 weeks after the last dose of LSD. A total of 48 subjects were enrolled.
The primary objective of this study is to assess the pharmacokinetic characteristics after a single dose of oral PBK-1801 in healthy Korean women for preparing the bridging data for Koreans.
The purpose of this study is to evaluate the safety for up to two doses of NasoShield, to determine if antibodies that protect against anthrax are formed after treatment with NasoShield, and to determine whether the formation of these antibodies are affected by different positions of administration.
An open-label, randomized, single-dose, two-period, two-group, crossover study was conducted in 60 healthy Chinese volunteers under fasted or fed conditions (30 volunteers for each condition) to assess the bioequivalence between two formulations of cefprozil.
In Part 1, the primary objective is to investigate the effect of multiple doses of itraconazole, an inhibitor of CYP3A4, on the pharmacokinetic (PK) profile of a single dose of ASTX660. In Part 2, the primary objective is to investigate the effect of a single dose of ASTX660 on the pharmacokinetics of the CYP3A4 substrate midazolam and its metabolite, 1-hydroxy midazolam. Safety and tolerability of a single dose of ASTX660 in the absence and presence of multiple doses of the CYP3A4 inhibitor itraconazole and in the presence of a single dose of the CYP3A4 substrate midazolam will also be evaluated.
Randomized, double blind, parallel group, single dose, 3 arm study to investigate and compare the PK, safety and immunogenicity profile of MB02-DM with MB02-SP and US-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.
To establish the range of TMADmid、TMADmidpt% by using tissue motion tracking of mitral annular displacement (TMAD), and to explore the influencing factors.
The COVID-19 pandemic, commonly referred to as "coronavirus", first began in the city of Wuhan, China in December 2019. This virus has since spread globally, with infections reported in nearly every country. COVID-19 targets the body's respiratory system, where infections can be found in the nose, throat and lungs. The effect of COVID-19 infection is very variable, where many people might not know that they have been infected and have recovered from COVID-19. However, COVID-19 infection can cause people to have difficulty breathing. This can be severe enough to require hospitalisation and potentially intensive care treatment. While they are being treated in hospital, COVID-19 infected patients can be found to have inflamed tissue in their lungs (referred to medically as "pneumonitis"). This inflammation is thought to be caused by their body's immune systems overacting to the infection rather than the COVID-19 virus itself. By potentially dampening down this overreaction of their immune system, it is hoped that COVID-19 patients with inflamed lungs have better and quicker chance to survive. Mesenchymal stromal cells (MSCs) have been shown to have anti-inflammatory and healing properties on injured tissue. MSCs have been trialled in various diseases but have not yet been tested on patients with COVID-19. In this study, the investigators will obtain bone marrow from healthy volunteers to develop a cell-based treatment for COVID-19-related pneumonitis. The investigators will also determine whether it is feasible to recruit bone marrow donors in a clinically useful timeframe to treat COVID-19 patients. A future trial, COMET20, will use the bone marrow-derived MSCs (BM-MSCs) manufactured in COMET20d to treat COVID-19 patients suffering with pneumonitis, to determine whether the BMMSCs can reduce the likelihood for mechanical ventilation and reduce hospitalisation.
The purpose of this study is to assess the safety, tolerability and pharmacokinetics of NNZ-2591 when administered to healthy volunteers.
Background: Researchers think that people s mental health and behavior will be very affected by the steps taken to slow the spread of COVID-19, such as social distancing. Also, the threat of disease and death, to people and their loved ones, can cause much stress. Researchers want to learn more about these stressors and how they are affecting people. Objective: To study the relationship of affective, cognitive, and behavioral responses to stressors related to COVID-19 with neuroimaging and behavioral data collected before COVID-19. Eligibility: English-speaking adults age 18 and older Design: This online study will include both new participants and those who have taken part in past National Institute of Mental Health studies. All will complete the same surveys and tasks. Participants will give their name and email address. They will get a username and password. The file that links their username to their personal data will be kept secure. Participants will complete a set of surveys about the following: - Sociodemographic data, such age, race, and income - Education and work status - Mental and medical illness and treatment - Family medical history - Mood - COVID-19 experience - Anxiety - Substance and alcohol use - Attention control - Other mental health related topics. Participants will complete a finger-tapping task. For this, they will press a key a certain number of times in a limited period. They will get to practice the task. After the task, they will complete a survey about it. It will take about 1 hour to complete the surveys and the task. About 8 months later, participants will be contacted to repeat the surveys and task. Compensation is provided.
