Healthy Clinical Trials in Saint Paul, MN

The purpose of this study is to find out whether insulin, a drug approved by the FDA for the treatment of diabetes mellitus, reaches the brain and spinal cord when delivered as a nasal spray (intranasally). Intranasal insulin has been shown to improve memory and mood in patients with mild cognitive impairment and dementia, but more evidence is needed to support the ability to effectively target the brain through intranasal routes. 12 healthy adults will be randomly assigned to receive a single dose of either 40 units ("low dose" group) or 80 units ("high dose" group) of insulin. Participants will undergo image-guided lumbar puncture (spinal tap) performed by a study radiologist. Samples of cerebrospinal fluid (a fluid surrounding the brain and spinal cord) and blood will be collected at 5 timepoints during the lumbar puncture: once prior to the administration of intranasal insulin, and again at 10, 20, 30, and 40 minutes after the dose is given. Samples will be tested to determine the level of insulin detected in the cerebrospinal fluid and blood at each time point. Results of this study will provide essential information about the ability of the SipNose device to effectively deliver insulin to the central nervous system of humans as measured in the cerebrospinal fluid.

The purpose of the study is to look at how various tablets of a study medicine called vepdegestrant are processed in the body. This will be studied in healthy adult participants after food. This study looks at how the medicine is changed and removed from the body after a participant takes it. This study is seeking for participant who: are healthy males, and healthy females who do not have the possibility to have children. are 18 years of age or older. weigh more than 45 Kilograms (99 pounds). The study consists of 3 treatments. Each participant will be assigned by chance to receive the 3 treatments in a certain sequence. This will be done over 3 study periods. Each treatment consists of a single amount of vepdegestrant taken by mouth in each study period. There will be a washout period between each study periods. The washout period is the time allowed for the medicine to get washed out from the body. How the medicine was processed will be calculated following each dose in each period. The total study duration is about 13 weeks. Read Less

The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called Lorlatinib) in health participants. This study is seeking participants who: Must be male or female of 18 to 75 years of age, inclusive at the time of the study. Are willing and able to comply with all scheduled visits, treatment plan, and other study procedures. Have a BMI (body mass index) of 17.5 to 40 kg/m2; and a total body weight >50 kg (110 lb). Are capable of giving signed informed consent document. All participants in this study will receive Lorlatinib. Participants will be placed into 1 of 3 cohorts based on their hepatic (liver) function. Participants will take Lorlatinib once by mouth. We will examine the experiences of people receiving the study medicine. This will help us determine if the study medicine is safe and effective. Participants will take part in this study for up to 35 days. Read Less
