Filter by:Poor adherence to tenofovir (TDF) and emtricitabine (FTC) for Human Immunodeficiency Virus (HIV) pre-exposure prophylaxis (PrEP) is common and the leading cause of therapeutic failure. The investigators need better ways to measure adherence in patients on PrEP. This application will address the need to measure adherence by evaluating an integrated technology system, Proteus Discover, when combined with Truvada. The Proteus Sensor System (PSS) will confirm that Truvada was taken, monitor adherence in both recent and long term dosing, and provides feedback to encourage adherence. The goal of this study is to determine whether the use of the PSS with Truvada will vary the drug concentrations of FTC/TDF. Participants will have 2 study visits where they will be randomized to either start with the combined PSS with Truvada or just Truvada alone. Study participants will come to the Clinical & Translational Research Center (CTRC) in the morning and take the assigned dose and will then have blood drawn at about .25, 0.5, 1, 2, 4, 6, and 10 hours after medication is taken. Participants will then return to the CTRC for blood draws 24, 48, and 72 hours after they took the dose on the first day. The second visit will mimic the first except that the participant will take the other dose form.
Finerenone is developed for the treatment of diabetic kidney disease (adults) and chronic kidney disease (children). The purpose of the proposed trial is to test the pharmacokinetics of a novel liquid formulation for the treatment of children in comparison to the adult tablet formulation.
Finerenone is developed for the treatment of diabetic kidney disease (adults) and chronic kidney disease (children). The purpose of the proposed trial is to test the pharmacokinetics of a single oral dose of finerenone (1.25 mg tablet and 5 x 0.25 mg tablets) using a novel orodispersible tablet formulation for the treatment of children, in comparison to the adult tablet formulation.
Evaluate the potential effect of hepatic or renal impairment on the pharmacokinetics, safety and tolerability of BAY 1841788 (ODM-201).
This is a two-part study to be conducted at a single study site in the US. Both parts of the study may be conducted in parallel. A total of approximately 38 subjects will participate in this study, with approximately 19 subjects in Part 1 and approximately 19 subjects in Part 2. Each subject may only participate in one of the parts.
This two-part study was designed to evaluate the pharmacokinetics (PK) of single and multiple doses of apremilast in healthy adult Korean males.
This is a Phase 1, open-label, single-center, non-randomized study to assess the mass balance of a single oral dose of DS-8500a in healthy male subjects, 18 years (y) to 60 y of age, inclusive. The radiolabeled investigational medicinal product will be administered to 12 healthy male subjects in 2 cohorts of 6 subjects each.
Study will assess the effects of itraconazole on the pharmacokinetic (PK) parameters of single-dose DS-8500a in healthy subjects. This is an open-label study in healthy subjects.
Introduction: The risk of systemic toxicity when using bupivacaine is a persistent problem, making its pharmacokinetic study crucial to the safety of regional anesthesia (RA). Little evidence exists regarding the effect of different concentrations of this drug on peak plasma levels. The present study compares two bupivacaine concentrations to establish how the concentration and exchange area affect the peak plasma level of this drug during axillary brachial plexus block. Latency and postoperative analgesia periods were also compared. Methods: 32 patients were randomly assigned to two groups. In the 0.25% group, 10 ml of 0.25% bupivacaine was injected per nerve; in the 0.5% group, 5 ml of 0.5% bupivacaine was injected per nerve. Peripheral blood samples were collected every 15 min during the first hour and every 30 min during the second hour to establish serum level dosage. High-performance liquid chromatography coupled with mass spectrometry was used for the analysis.
This is a single center, randomized, double-blind, placebo-controlled study to assess the pharmacokinetics, safety, and tolerability of subcutaneous administration of TEV-48125 (single ascending doses and single doses up to 900 mg) in Japanese and Caucasian healthy subjects.
