Healthy Paid Clinical Trials in Arizona

Background: Diet-induced thermogenesis (DIT) is the amount of energy one s body uses to eat food, absorb the nutrients from the food, and process those nutrients. Researchers would like to understand more about how changing the balances of protein, fat, carbohydrates, and total calories in the diet can affect DIT. Objective: To learn how different diets can change a person s DIT. Eligibility: Healthy people aged 18 to 60 years who have not intentionally lost weight in the past 6 months. Design: Participants will stay in a clinic for about 35 days. They will eat only the food provided. They will receive 8 different diets during the study, including 7 test diets. Participants will undergo multiple tests. They will be screened with blood and urine tests and a test of their heart function. During the first few days: Their waist, thigh, and neck circumference will be measured. They will have a DXA scan: They will lie on a padded table for about 20 minutes while an instrument measures the amount of fat in their body. They will be tested for diabetes. They will answer questionnaires about topics including eating behavior, hunger, and stress. Throughout the study: Their weight will be measured daily. Blood tests will be repeated. They will stay in a metabolic chamber a total of 9 times. They will remain in a closed room for 24 hours while researchers monitor the room temperature and levels of oxygen and carbon dioxide. Participants will collect all their urine for each 24-hour period. ... Read Less

This study is the first study with TAK-004 conducted in human beings. Participants will receive either TAK-004 or placebo. The main aim of this study is to learn how safe TAK-004 is in healthy adults and how well participants tolerate one or more doses of TAK-004. Other aims are to learn about the effects of TAK-004 on the heart rate and blood pressure and if TAK-004 creates an immune response (immunogenicity). Another aim is to learn how the body of healthy adults affects TAK-004 (pharmacokinetics). Participants will receive TAK-004 or placebo via injection just under the skin (subcutaneous injection or SC injection). Depending on the groups participants are assigned to, they will either receive just one dose of TAK-004 or placebo or multiple doses of TAK-004 or placebo while they are in the study. Blood and urine samples will be taken during the study. Read Less

Researchers designed belzutifan, the study medicine, to treat certain kinds of cancer. The goal of this study is to learn what happens to belzutifan in a healthy person's body over time when taken, by mouth, as a tablet. Researchers will learn what happens when belzutifan is taken alone and when it is taken after several days of treatment with phenytoin. Read Less

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.... Read Less

This study consists of 2 parts, Part A and Part B. Part A is a single center, randomized, double-blind, placebo-controlled cohort designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of NMRA-323511 among healthy elderly. Part B is a multicenter, randomized, double-blinded, placebo-controlled, parallel-group cohort to evaluate the safety, tolerability, and efficacy of NMRA-323511 among adults with Agitation Associated with Dementia due to Alzheimer's Disease. Part A consists of a Screening Period (up to 28 days), a 10-day Treatment Period, and a 10- day Follow-up clinic visit after last dose of study treatment. Part B consists of a Screening Period (up to 28 days), an 8-week Treatment Period, and a 10-day Follow-up clinic visit after last dose of study treatment. Read Less

The purpose of the study is to assess the effects of multiple doses of itraconazole (a strong CYP3A4 inhibitor) on single dose PK of casdatifan in healthy adults and to assess the effects of multiple doses of phenytoin (a strong CYP3A4 inducer) on single dose PK of casdatifan in healthy adults.

This study will be conducted to evaluate a Single-Dose Subcutaneous (SC) Axatilimab Compared With Intravenous Axatilimab in Healthy Participants. Read Less

The purpose of this study is to evaluate the safety and immunogenicity of a single intramuscular injection of different formulations of a hexavalent influenza messenger ribonucleic acid (mRNA) vaccine composed of differing dose levels of trivalent (TIV) mRNA hemagglutinin (HA) in combination with TIV mRNA-neuraminidase (NA) compared to an active control ((Fluzone standard-dose quadrivalent influenza vaccine (QIV-SD) or Fluzone high-dose quadrivalent influenza vaccine (QIV-HD) in adults 50 years of age and older.

The purpose of this study is to investigate the safety, tolerability, and pharmacokinetics of BMS-986419 (Part 1) and the effects of multiple doses of BMS-986419 on cardiac repolarization (Part 2) in healthy participants. Read Less

The purpose of this study is to investigate the impact of the probiotic Lactobacillus rhamnosus (LGG) on proton pump inhibitor (PPI)-induced changes to the microbes that live in the gastrointestinal tract and are passed out in the stool. PPI medicines reduce stomach acid and are commonly used to treat acid reflux disease. Read Less
