Filter by:Background: Researchers use mixed meal tolerance tests (MMTTs) to look at how people s bodies respond to eating a meal. However, researchers do not agree on how to decide the number of calories to give in each meal. Some use fixed meals, which are the same size for everyone, and some use adjusted meals, based on the size of the person s body. Researchers want to know which MMTT is best to use for future research. Objective: To learn how fixed vs adjusted meals affect blood glucose levels in healthy people. Eligibility: Healthy people aged 18 years or older. Design: Participants will have 3 or 4 clinic visits of up to 8 hours in 8 weeks. Participants will have baseline tests: Their height, weight, and waist size will be measured. They will have an oral glucose tolerance test: A needle attached to a tube (IV) will be inserted into a vein in the arm. They will have a sugary drink. Blood samples will be taken from the tube at intervals up to 3 hours after the drink. They will have a body scan. Participants will have 2 MMTT visits. One will include a fixed meal and one will include an adjusted meal. They will have tests at both visits: Resting metabolic rate: A clear hood will be placed over the participant s head while they rest for 20 minutes. This will measure the oxygen they breathe in and out. MMTT. Participants will have 5 minutes to drink a liquid meal. Blood samples will be taken at intervals for the next 4 hours....
Researchers are looking for a better way to treat men who have advanced non-small cell lung cancer (NSCLC). NSCLC is a group of lung cancers that have spread to nearby tissues or to other parts of the body. Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) are proteins that help cells to grow and divide. A damage (also called mutation) to the building plans (genes) for these proteins in cancer cells leads to a production of abnormal EGFR and/or HER2. These abnormal proteins drive the growth and the spread of the cancer. Several EGFR and/or HER2 mutations exist in the cancer cells. The study treatment works by blocking the mutated EGFR and HER2 protein present in NSCLC cells and may help stop the further spread of NSCLC. BAY2927088 is under development, once it is approved, it may help treat people with NSCLC. The participants of this study will be healthy men and will have no benefit from the administration of BAY2927088. However, the study will provide important information for the design of subsequent studies with BAY2927088 in people with NSCLC. The participants in this study will get the non-radiolabeled and radio-labeled study treatment BAY2927088 in the form of tablets and solution by mouth and as an intravenous infusion in the arm. By radiolabeling the study treatment, researchers can track its movement and breakdown in the body of the participants. During the study, the study team will do physical examinations, take medical history, ask the participants questions about their smoking or alcohol consumption habits and other medications used, check vital signs such as blood pressure, heart rate, body temperature and the number of breaths taken per minute (respiratory rate), take blood and urine samples, do HIV (human immunodeficiency virus), hepatitis and optional COVID-19 tests per local regulations, and examine heart health using electrocardiogram (ECG). Each study participant will go through a first test phase (screening) of up to 28 days before the start of treatment. The study will have two parts. In part 1, the study participants will take a single dose of the non-radiolabeled study treatment in the form of tablets by mouth 30 minutes following a light meal. They will then receive the radiolabeled study treatment as an intravenous infusion in the arm over 15 minutes. After 2 days of washout, the same group of participants will move on to Part 2 of the study. They will take a single dose of the radio-labeled study treatment as a solution by mouth 30 minutes after a light meal. The participants and the study team know what treatment the participants will take. The total duration of the study will be approximately 8 weeks per participant, including an in house stay of approximately 23 days and 22 nights. There will be a final examination on the last day of their in-house stay before the participants are discharged and go home. The study doctors and their team will contact the participant to learn about the participant's health until the participant completes the study.
Evaluation of the efficacy of different treatment protocols in the management of Oro-Antral Communications.
This is a first-in-human (FIH), randomized, placebo-controlled, double-blind, single ascending dose (SAD) study to assess the safety and tolerability of VIS954, a monoclonal antibody, in healthy adult male and female participants.
The purpose of this study to assess the relative bioavailability of 5 mg Mavacamten opened capsule administered via nasogastric tube compared to intact oral 5 mg Mavacamten in healthy volunteers.
The primary objective of this clinical study is to evaluate the effect of repeated oral doses of avacopan (30 mg and 60 mg twice daily approximately 12 hours apart [BID]) given under fed conditions on the PK of a single dose of simvastatin (40 mg) in healthy volunteers.
Leucettinib-21 First-in-Human Phase 1 Study in 4 Parts: Single (Part 1) and Multiple (Part 3) Ascending Doses, and Food-Effect (Part 2) in Healthy Subjects, and Single Dose (Part 4) in People with Down Syndrome (DS) and Alzheimer's Disease (AD). For Parts 1, 3 and 4, safety and tolerability of an oral administration of Leucettinib-21 will be assessed as primary objectives. Pharmacokinetics and pharmacodynamic biomarkers will be investigated as secondary objectives. For Part 2, the effect of high fat meal will be evaluated on the pharmacokinetics parameters after an oral administration of Leucettinib-21.
Use of intraosseous Doppler ultrasonography to study skeletal physiology ("Echo-Os Study"). Exploratory study before its use in space physiology. Bones have a complex vascular network providing nutrients and oxygen to bone cells. The physiology of intraosseous blood circulation remains very little known to date, particularly in human. Human bone vascularization studying is very difficult because of a lack of simple tools for functional exploration of bone vascular perfusion. For blood flow studies, ultrasonography is best suited, allowing for dynamic non-invasive measures. Bone has until now been considered to stop ultrasound and therefore prevent any intraosseous measurements. From a physics viewpoint, bones conduct ultrasound waves well, but they are reflected differently compared to soft tissues. A specific analysis of the ultrasound returned by the bone, using specific correction factors, is therefore needed to interpret ultrasound signals, reconstruct an anatomical image, and extract physiological information. The system proposed in this study combines standard conventional low-frequency ultrasound probes with a specific analysis of ultrasound wave reflection. This system makes it possible to reconstruct an anatomical bone image and record the pulsatile signal of intraosseous vascular perfusion. The investigators will use this system to study the vascular reactivity induced by different physiological maneuvers. This protocol proposes to study the following mechanisms of blood flow regulation at the level of tibia cortical bone: flow-mediated dilation induced by endothelium (with arterial occlusion test), vasoconstriction induced by sympathetic activation (with static handgrip test), and vasoconstriction induced by veno-arteriolar reflex (with venous occlusion test). This is a pilot study in physiology performed with healthy volunteers. This study will verify whether our intraosseous ultrasound system can properly measure physiological responses expected during these maneuvers. This protocol will also establish links between perfusion and bone architecture at tibial level.
