Filter by:A pharmacokinetic study in healthy volunteers to determine the relative bioavailability of three formulations of celecoxib to the approved formulation.
The purpose of this study is to determine the safety, tolerability, pharmacokinetics and pharmacodynamics (how the drug effects certain target sites of activity in the body) of escalating doses of oral PF-04171327 in healthy volunteers for 14 days (Part 1). Part 2 will evaluate the pharmacokinetics of a single 10 mg dose of the PF-04171327 tablet in healthy volunteers.
This is a single center, Phase I, open-label, single-blind (subjects blinded to the contents of each injection), 4 stage study designed to determine the PK, GD, safety, tolerability, and optimal ratio of rHuPH20 administered with fixed Humulin R or Humalog doses in healthy subjects.
This study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of PF-04629991 in healthy subjects. Dose exploration will proceed in a step-wise manner, beginning with low doses not expected to have significant biological effects and proceeding to doses approximating or exceeding the anticipated therapeutic level. Doses to be explored may be limited by tolerability, and will not exceed levels previously shown to be tolerable in animals.
Single Ascending Dose Study
This is a sub-study of a drug development study conducted by Pfizer, Inc. It will evaluate how well people who participate in research studies understand from the study consent form what the purpose of the study is, the risks and benefits of participating, the procedures they will undergo and their right to withdraw from the study before it ends. It will compare the understanding and satisfaction of those who are given a standard consent form with those who are given a simpler, concise consent form and examine how their understanding of the information is affected by the length, complexity, format, and reading level of the document. People 18 years of age and older who are participating in a Pfizer drug development study and who are able to read and write English may be eligible for this sub-study. Participants in Pfizer's drug development study who agree to participate in this sub-study are randomized to receive either the standard consent form or the concise consent form. The standard consent consists of a detailed, multiple page consent form. The concise form is simpler, written at a lower reading comprehension level. Both forms contain all of the required elements of informed consent according to federal regulations, and include information needed to make a decision about participating in the study. Each form also contains information regarding participation in this sub-study. The standard group signs the standard consent form; the concise group is given the standard consent after reviewing the concise form and is asked to review and sign it. After reviewing the consent form for the main study, participants complete a 20-minute questionnaire that includes questions that measure understanding of study information such as its purpose, risks and benefits, compensation schemes, and other information. Additional questions ask about how the participants made the decision to enroll in the study.
To determine the effects of repeated doses of AZD7325 on the pharmacokinetic profile of a CYP3A4 substrate (midazolam and its 1' hydroxy metabolite) and a CYP1A2 substrate (caffeine and its paraxanthine [3-desmethyl] metabolite).
This study is being done in healthy volunteers to help researchers understand how ABT-614 works in the human body, specifically in the brain. The PET imaging technique can be thought of as a way to take pictures of chemical changes in the brain. To take a PET scan (picture), a substance with low levels of radioactivity (radiotracer) has to be injected when you are in the PET camera. The radiotracer is only radioactive for a short period of time. In this study, PET is being used to measure how the study drug attaches to specific receptors in the brain. The radiotracer used in this study, [11C]-(+)-PHNO, is currently being used for studies in people at the CAMH PET Centre.
The hypothesis of this study is that subcutaneous administration of tanezumab results in lower drug exposure compared to intravenous administration of tanezumab.
We are interested in how skeletal muscle processes fat and how this may affect insulin resistance. This is an important question since insulin resistance predates and predicts type 2 diabetes. We know that if pharmaceutical grade fat is infused into people, they develop insulin resistance. Likewise, we would like to infuse pharmaceutical grade fat into trained subjects, believing that trained subjects will have less insulin resistance, less decline in muscle energy function, and less accumulation of fat metabolites than untrained subjects. For comparing the effects of the pharmaceutical grade fat infusion, we will also have a group of trained and untrained subjects given a control (glycerol) infusion. Glycerol is basically the same as pharmaceutical grade fat infusion without the fat component.
