Study Design This is a Phase 1, multi-center, extension study to collect safety data up to 75 ± 10 days postdose from the Phase 1 studies RPC01-1912, RPC01-1913 and RPC01-1914 (ie, the "parent studies") and PK/PD data up to 75 ± 10 days postdose from studies RPC01-1913 and RPC01-1914. This study consists of two parts: - Mandatory data collection for safety: Subjects enrolled in the parent studies were consented to have data on adverse events (AEs), serious adverse events (SAEs), pregnancy test results, and concomitant medications up to the 75 ± 10 days postdose follow-up collected and reported in this study. - Optional sparse sampling for PK/PD: Eligible subjects from studies RPC01-1913 and RPC01-1914 will be offered the opportunity to return to the clinical research unit (CRU) at four separate occasions for PK/PD sample collections up to the 75 ± 10 days postdose follow-up. After signing the informed consent form, eligible subjects will be randomized to one of three sequences with stratification by site/protocol. Subjects will return to the CRU in the morning (between approximately 8 am and 11 am) once at each of the four time windows. Study Population The approximate number of subjects will be 230 for safety data and 129 for PK/PD data. Length of Study The study duration is up to 84 days.
This is a randomised, double blind placebo controlled Phase I study which will assess the safety, tolerability and PK of Cortexolone 17α-propionate (and its metabolites), and its effects on the QTc interval when administered as multiple doses to healthy adult volunteers. Volunteers will receive a morning and evening dose (12 hours apart) of 225 mg (3 mL Cortexolone 17α-propionate applied topically as a 7.5 % solution (75 mg in 1 mL), giving a total daily dose of 450 mg (6 mL) per individual.
2 different formulations and 4 different single doses of tafamidis will be compared. All subjects will receive both formulations and 3 different doses. Subjects will be fasted before taking the drug. After swallowing single dose of tafamidis, tafamidis blood concentrations will be measured periodically for 8 days. After another 16 days, all subjects will repeat the procedure twice, each time with the other formulation/dose.
Nanoparticles (NPs) are minute pieces of material to which we are exposed every day in the air we breathe. Some are naturally occurring and have no impact on health, whereas others are produced from urban air pollution and can worsen diseases, particularly in the lungs and blood vessels. However, there is great interest in developing new NPs because of their unique properties that are useful for many applications, such as engineering, electronics and for drug delivery. At present it is unclear exactly what effects inhaled NPs have. Our current programme of research is designed to assess whether a specialized group of fats made in the body (called eicosanoids) drive the cardiovascular effects of NPs. The changes in the profiles of these fats will provide unique fingerprints that could be used to predict the actions of new NPs. In the proposed clinical study we shall investigate the effects of both environmental and manufactured carbonaceous NPs on the lungs, blood vessels, blood clotting, and levels of eicosanoids in blood and urine. We have previously investigated the cardiovascular effects of carbon nanoparticles after inhalation in man, and these experiments will investigate how the shape, size and composition of carbon particles influence these responses. These experiments will provide new insight into how NPs affect the body and pave the way for new ways to predict the toxic effects of NPs (reducing the need for animal experiments). The findings will enable the design of novel NP without the harmful characteristics of those found in air pollution.
This is an open-label, non-randomized, successive cohorts design, multicenter, single dose phase I study. The primary objectives are: - to evaluate the pharmacokinetics (plasma and urine) profile of P03277 following single intravenous injection (0.1 mmol/kg body weight) in patients with mild to severe renal impairment and in healthy volunteers with normal renal function used as reference. - to assess dialysability of P03277 following a single intravenous injection (0.1 mmol/kg body weight) in patients with end stage renal disease requiring hemodialysis.
The study is a Phase I, Single center, Randomized, Cross-over Double-blind Placebo-controlled and Open-label Positive-controlled (moxifloxacin) in healthy volunteers. The primary objective is to assess the cardiac safety after administration of P03277 to 48 healthy volunteers at dose of 0.1 mmol/kg (anticipated clinical dose) and 0.3 mmol/kg (supra-clinical dose) by evaluating the QT and QTc intervals.
The purpose of this study is to learn about a drug-drug interaction. When two medications are taken together at the same time, one medication may change the activity of the other medication in the body - this is called a drug-drug interaction. This study is looking at the effect the Bayer study drug, copanlisib, has on metformin, a commonly used medication to treat diabetes. During the study, blood and urine samples will be collected and analyzed to learn about pharmacokinetics (how copanlisib changes metformin levels in the body) and pharmacodynamics (the effect metformin has on the body when taken together with copanlisib) when someone takes both copanlisib and metformin together.
The ID-Cap System is classified as an ingestion event marker (IEM), a Class II medical device. The system is intended to record time-stamped ingestions with the ingestible sensor, ID-Tag which transmits a signal to a wearable device, the ID-Cap Reader. In this study, 12-18 subjects will ingest capsules containing ingestible sensors while wearing the Reader and being observed in a clinic setting.
Background: Dopamine is a natural chemical in the brain that may influence eating behavior and physical activity. Researchers want to measure the brain s dopamine activity and understand how it differs in people with obesity. Objective: To better understand how brain function, particularly dopamine activity, relates to body weight and eating behavior. Individuals may be able to participate if they: Have a BMI of at least 18.5 kg/m2 Are weight-stable and generally healthy Are between ages 18-45 years Have normal blood pressure Are not using illegal drugs (based on urine drug screen) Are not following a special diet Do not have metal implants Design: Participants will be screened with: - Medical history - Physical exam - Questionnaires and an interview to see if it is safe to have a PET/MRI scan - Fasting blood and urine tests - Participants will eat a special diet given to them for the 5 days before their inpatient visit. Participants will have a 5-day inpatient visit. Some days include blood and urine tests. Each day includes surveys and tests to measure habits and likes/dis-likes. A sample schedule may be: Day 1: Participants will wear a monitor that uses a needle below the skin to measure glucose. Their body fat will be measured with low-dose x-rays Day 2: Participants will have a PET scan. They will lie on a table that slides in and out of a donut-shaped scanner. They will be injected with a small amount of a radioactive substance and wear a cap on their head. Day 3: Participants will have an MRI. They will lie on a table that slides in and out of a scanner. Day 4: Participants will have another PET scan. This time, they will drink a milk shake during a break from the scanner. Then, they will go back inside the scanner for the end of their scan. Day 5: Participants will wear a hood for up to 40 minutes to measure their breathing. They will also drink special water and collect samples of their urine to measure the rate they burn energy. For 12 months after the visit, participants will track their weight and physical activity daily using a special scale and activity monitor. A few times over the year, the study team will send participants special activity monitors to use for 7 days at a time. Participants will have an in-person 1-day follow-up visit. This includes most tests except for PET scanning....
