Filter by:The purpose of the study is to assess the safety, tolerability, pharmacokinetics, and pharmacodynamic effects of single oral doses and multiple oral doses of JNJ-38877618 administered for 7 consecutive days in healthy adult male participants.
The purpose of the study is to assess the safety, tolerability and PK of selumetinib (AZD6244; ARRY-142886) (Hyd-Sulfate) in healthy male Japanese and non-Japanese Asian volunteers following administration of a single dose. Standard safety assessments including ECGs, vital signs, blood/urine safety tests, PK samples and monitoring of adverse events and an optional exploratory pharmacogenetics will be performed.
The purposes of this study are to determine the effects of baricitinib on the time it takes to remove simvastatin from the body and to look at how well-tolerated and safe baricitinib is when given alone and in combination with simvastatin. Side effects will be documented. The study will last approximately 7 days from the first dose to the end of the study (not including screening or follow-up).
The main purpose of this study is to look at the effect of evacetrapib on pravastatin levels in the blood when both drugs are taken at the same time. The study will also assess how well the body handles evacetrapib and pravastatin when given at the same time. This study has two periods in fixed order. Each participant will enroll in both periods. This study will last approximately 25 days, not including screening.
The purpose of this study is to evaluate the safety, tolerability and Pharmacokinetics/Pharmacodynamics of multiple doses of GCC-4401C in healthy male subjects.
To determine the relative bioavailability of different oral formulations of AZD9291 and the effect of food in healthy volunteers.
Background: - Changes in how a person s body burns energy or calories can affect their weight over time. The lowest level of energy the body needs to function is called basal metabolic rate. In the cold, we burn extra energy, even before we start to shiver. This is called non-shivering thermogenesis and it occurs in different types of tissue such as muscle and fat. Researchers want to learn more about this type of energy burning and how it is regulated. They hope this will help treat obesity in the future. Objectives: - Sub-study 1: to better understand how non-shivering thermogenesis works. - Sub-study 2: to measure the effects of anti-obesity drugs on basal metabolic rate. - Sub-study 3: to better understand the effects of mirabegron, a beta-3 adrenergic receptor agonist, on brown fat activity. Eligibility: - Healthy, lean adult males ages 18 to 35. Design: - Participants will be screened with medical history, physical exam, blood test, and EKG. - For sub-studies 1 and 2: - Participants will receive one X-ray scan. - Each day, all participants will: <TAB>- Have height and weight measured, and have urine collected. - Spend 4 hours in a temperature-controlled room with furniture, toilet area, phone, and computer. They will wear small non-invasive devices to monitor activity, heart rate, temperature, and shivering. <TAB>- Walk for 30 minutes. -For sub-study 3: - Participants will receive one DXA scan and up to 4 PET/CT scans and 4 MRIs - Each stay, all participants will: <TAB>- Have height and weight measured, and have urine collected. - Spend 6 hours in a temperature-controlled room with furniture, toilet area, phone, and computer. They will wear small non-invasive devices to monitor activity, heart rate, temperature, and shivering. - Participants will be compensated for their time and participation at the end of the study
This project is designed to study whether pomegranate extract benefits cognitive abilities in middle-aged and older non-demented volunteers. Subjects will be randomly assigned to one of two treatment groups: either a placebo or the pomegranate extract supplement. Both the placebo and pomegranate extract will be packaged in 1000 milligram capsules to maintain blindness. Subjects will take one 1000 milligram capsule daily for twelve months. The investigators expect the people receiving the pomegranate extract supplement to show better cognitive performance compared with those receiving a placebo after one, six, and twelve months. The investigators believe cognitive decline and treatment response will vary according to a genetic risk for Alzheimer's. The investigators will study 212 non-demented subjects aged 50-75 years. Initially, subjects will undergo a clinical assessment, an MRI and a blood draw to determine genetic risk and to rule out other neurodegenerative disorders linked to memory complaints. Subsequently, subjects will undergo the first memory (or neuropsychological) assessments. Following the first assessment, subjects will begin taking the supplement (either the pomegranate extract or the placebo). Subjects will undergo a brief memory test at one-month mark. At six months, subjects will have a second, full neuropsychological assessment. The final assessment will take place at the end of the study, the 12-month mark. Additional blood will be drawn at baseline and at 12 months and frozen to assess inflammatory markers if outcomes are positive. Subjects will also be asked to come to the University of California, Los Angeles (UCLA) at 3 and 9 months for supplement refills. In total, subjects will be expected to come to UCLA for 7 visits during the course of 12-13 months.
This single center, open-label, 3-period, fixed-sequence study will evaluate the effect of multiple oral doses of rifampin on the pharmacokinetics of a single oral dose of RO5424802 in healthy volunteers. Subjects will receive a single dose of RO5424802 on Days 1 and 17 and rifampin daily from Days 8 to Day 20.
The purposes of this study are to assess how the body handles baricitinib when it is given with another drug called probenecid. The study doctor will measure the amount of baricitinib that is absorbed into the blood stream and the time that it takes to remove baricitinib from the body. The safety and tolerability of these drugs will be studied. The study will last about 18 days from the first dose to the end of the study (not including screening.)
