Filter by:This is a randomized, blank-controlled study in adults with household contact exposure to individuals with SARS-CoV-2 infection. All subjects in the study will be household contacts with close exposure to the first household member known to be newly infected with SARS-CoV-2. Subjects in each cohort will be randomly assigned to the Chinese herbal medicine treatment group or blank control group in a 4:1 ratio, followed by 1 week of the treatment period and 2 weeks of follow-up.
The purpose of this study is to evaluate the drug absorption of atazanavir and cobicistat between the coadministration of the mini-tablet formulations in applesauce or chocolate pudding followed by water and the coadministration of atazanavir oral powder in applesauce and cobicistat oral tablet followed by water in healthy adult participants.
This study is being done to learn about the binding of Lu AG06466 and its major breakdown product (Lu AG06988) in the brain of healthy men having received multiple doses of Lu AG06466. As the binding will result in inhibition of an enzyme in the endocannabinoid system called monoacylglycerol lipase (MAGL), the effects on this system will be evaluated both in the blood and cerebrospinal fluid and compared to the binding in the brain.
This study is to characterize mass balance and further the understanding of human pharmacokinetics, metabolism, and excretion of radiolabeled [14C]PF-07321332 in healthy male participants following oral administration with ritonavir.
ASP8731 is a potential new treatment for people with sickle cell disease. Before ASP8731 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. They do this to find a suitable dose and to check for potential medical problems from the treatment. This type of study usually includes healthy adults but can include people with the relevant condition. The main aim of this study is to learn if healthy adults have any medical problems after taking different doses of ASP8731. This study will be in 2 parts. In Part 1, different small groups of people will take lower to higher doses of ASP8731 or a placebo. In this study a placebo looks like ASP8731 but will not have any medicine in it. This is done to find suitable doses of ASP8731 and work out how often it should be taken. Some of this information will be used in Part 2 of the study. The first group will take the lowest dose of ASP8731 or the placebo. A medical expert panel will check the results from this group and decide which ASP8731 dose the next group can take. The panel will do this for each group until all groups have taken ASP8731 or until a suitable dose of ASP8731 has been reached. In Part 1, people will visit the study clinic 4 times. The first visit is to check if they can take part. People will be asked about their medical history, have a physical exam, and their vital signs checked (pulse rate, temperature, and blood pressure). Also, they will have an ECG to check their heart rhythm and have some blood samples taken for laboratory tests. For women this will include a pregnancy test. At the second visit, people will stay in the study clinic for a few days. In most groups, people will be picked to take either ASP8731 or the placebo by chance alone. They will fast before taking ASP8731 or the placebo. 1 group will take ASP8731 with food. No-one in that group will take the placebo. After taking ASP8731 or the placebo (or just ASP8731 with food), people in all groups will give blood and urine samples during the next 3 days. Also, they will be checked for any medical problems during their clinic stay. People will return to the study clinic for a 2 follow-up visits - at about 8 and 30 days after they last took ASP8731 or the placebo. At these visits people will be asked if they have any medical problems. They will have a physical exam, have their vital signs checked (pulse rate, temperature, and blood pressure), and have some blood samples taken for laboratory tests. For women, this will include another pregnancy test. In Part 2, other different small groups of people will take lower to higher doses of ASP8731 or a placebo. How often it is taken will be worked out from Part 1.The first group will take the lowest dose of ASP8731 or the placebo each day over several days. A medical expert panel will check the results from this group and decide which ASP8731 dose the next group can take. The panel will do this for each group until all groups have taken ASP8731. In Part 2, people will visit the study clinic 5 times. The first visit is to check if they can take part. People will be asked about their medical history, have a physical exam, and their vital signs checked. Also, they will have an ECG and have some blood samples taken for laboratory tests. For women this will include a pregnancy test. At the second visit, people will stay in the study clinic for several days. In all groups, people will be picked to take either ASP8731 or the placebo by chance alone. After taking ASP8731 or the placebo, people in all groups will give blood samples throughout their stay. They will give urine samples during the last few days of their stay. Also, they will be checked for any medical problems during their clinic stay. After discharge, people will return to the clinic 4 days later for a third visit. At this visit, they will have some blood samples taken for laboratory tests. Also, they will have their vital signs checked and will be asked if they have any medical problems. People will return to the study clinic for a 2 follow-up visits - at about 15 and 30 days after they last took ASP8731 or the placebo. At these visits people will be asked if they have any medical problems. They will have a physical exam and have their vital signs checked. They will also have an ECG and have some blood samples taken for laboratory tests. For women, this will include another pregnancy test. No other visits are planned during this study.
The purpose of this study is to evaluate the effects of co-administration of itraconazole or diltiazem on the single-dose pharmacokinetics of danicamtiv in healthy participants.
This interventional study aims to investigate the effect of deep breathing (DB) and transcutaneous electrical vagus nerve stimulation (tVNS) on heart rate variability (HRV) in healthy participants and patients with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE). HRV is used as a surrogate measure of vagal nerve tone. The study consists of three sub-projects: Sub-project 1: To compare the effect of one session of DB and one session of non-invasive auricular tVNS on vagal nerve tone measured by HRV in healthy participants and in patients with RA and SLE. The hypotheses is that DB has a similar effect on HRV as non-invasive electrical tVNS. Sub-project 2: A dose-response study in healthy participants comparing the effect of 5, 15 and 30 minutes of DB on HRV. The hypothesis was that HRV increases as a function of the number of minutes the DB is performed in healthy participants. Sub-project 3: To investigate the effect of the optimal dose found in sub-project 2 in patients with RA and SLE measured by HRV, and to investigate its reproducibility by doing it twice.The hypothesis was that HRV increases after DB in patients with RA and SLE, and the effect is reproducible. In all three sub-projects the washout period will be investigated by measuring HRV three times after the intervention. We hypothesise that the effect of DB and tVNS on HRV decreases over time.
The purpose of the study is to evaluate safety, tolerability, and pharmacokinetics (PK) of SRK-001 in Healthy Participants.
The main purpose of the study is to assess the injection site pain intensity of two formulations using prefilled autoinjector device in healthy participants.
This study will evaluate the effect of multiple oral doses of itraconazole, on the pharmacokinetics of etrumadenant when etrumadenant is administered as a single dose in healthy adult participants.
