Filter by:This was a Phase I study in 12 healthy male participants to compare the pharmacokinetic properties of CG5503 (how it is taken up and excreted from the body) after 2 minutes intravenous (i.v.) infusion with and without oral co-administration of charcoal to investigate a potential gastrointestinal secretion of CG5503. During the course of the study each participant received two infusions of 40 mg CG5503 without (treatment A) and with (treatment B) oral co-administration of charcoal. In treatment B, eight doses of 5 grams charcoal powder were co-administered orally at defined time points. The wash out phases were to be at least 4 to 14 days between the treatment periods.
The effect of multiple oral administration of two doses of CG5503 PR (prolonged release) compared to placebo on the electrical activity of the heart were investigated. The rationale to perform this study was to exclude any effect of CG5503 on the heart rhythm. This study was a randomised, double-blind, double-dummy, placebo- and moxifloxacin-controlled, 4-way cross-over study. Participants were given a combination of either CG5503 PR and placebo (medication with inactive ingredients which looks like the study drug) or moxifloxacin and placebo. Moxifloxacin was used as a positive control. It has consistently shown that it has an effect on the heart rhythm. Within 14 days prior to the first dosing, participants had a physical examination, a 12-lead electrocardiogram (ECG) was recorded and haematological, serological, biochemical, and urine analyses took place. A blood sample for optional genotyping of genes responsible for long QT syndrome was taken. During each dosing session, the participants were confined in the evening before baseline assessments were performed and stayed in the clinic until 48 hours after the last dosing. Study medication was administered on Day 1 and 2 in the morning (0.5 hours after breakfast) and in the evening (1.5 hours after dinner), and on Day 3 in the morning (0.5 hours after breakfast). Dosing was separated by at least 7 days between the last dosing of each period and the first dosing of next period. Interim analysis of ECG-data were performed after completion of 24 participants (group 1) with possible subsequent adjustment of sample size for group 2.
The objective of this study was to evaluate the pharmacokinetics (PK), safety and tolerability profile of cebranopadol (GRT6005) in patients with varying degree of renal impairment and participants with normal renal function after an oral single dose administration. This study was a Phase 1, multi-center, non-randomized, open-label, parallel group, single-dose study in up to 24 male and female patients with varying degree of renal impairment and participants with normal renal function. Within 14 days before the administration of cebranopadol the general eligibility of the participants for the study was assessed according to the inclusion/exclusion criteria. Estimated glomerular filtration rate (eGFR) was determined according to the Modification of Diet in Renal Disease (MDRD) equation. A treatment period from Day -1 to Day 8 was performed, with participant confinement to the study site from Day -1 to Day 6 and an outpatient visit on Day 8. A single dose of cebranopadol 200 μg was administered on Day 1. Multiple blood and urine samples were drawn for pharmacokinetic evaluations and safety laboratory monitoring. Additional blood samples were taken prior investigational medicinal product (IMP) administration to assess serum creatinine concentration and protein binding. An End-of-Trial Visit was performed at the time, or within 7 days, of the final blood sample on Day 8 or at early withdrawal.
This study characterises the pharmacokinetic (PK) profile of the active ingredients of PLENVU (NER1006) and their related substances/metabolites. Subjects will receive PLENVU.
Sepsis and septic shock patients are considered to have a high risk of complications and death. Appropriate antimicrobial therapy plays an important role in determining outcomes in septic patients. However, pathophysiologic changes associated with critical illness have an impact on pharmacokinetics of antimicrobials. In addition, increasing bacterial resistance is also a growing concern, especially in intensive care units., Consequently, standard antimicrobial dose may not be sufficient to achieve pharmacokinetic/pharmacodynamic target in sepsis and septic shock patients. The purpose of this study is to compare a therapy between meropenem standard dose and meropenem high dose in the treatment of sepsis and septic shock
Tacrolimus is a calcineurin inhibitor widely used for the prevention of allograft rejection in solid organ and bone marrow transplantation. It is characterized by a narrow therapeutic index and large inter-individual pharmacokinetic variability. Adoport® is an immediate-release formulation of tacrolimus, to be administered twice daily. Because of a narrow therapeutic window and a better correlation between pre-dose level and effects than between dose and effect, therapeutic drug monitoring (TDM) based on trough whole blood tacrolimus concentrations is recommended for Adoport®. TDM helps to minimize the risk of acute rejection and the occurrence of adverse effects (mainly nephrotoxicity and, to a lesser extent, neurotoxicity). As reported in a consensus document from a consortium of European experts on tacrolimus TDM, the interdose area-under-the curve (AUC0-12h) is expected to be the best marker of tacrolimus exposure. However, tacrolimus monitoring based on full AUC0-12h is difficult to set up in routine, due to clinical constraints and the necessity of multiple samples. Calculation of the AUC0-12h using Bayesian estimation and a limited sampling strategy, i.e. a few blood samples collected during the early phase post-dose would represent an elegant solution, as already done for other tacrolimus formulations. Furthermore, the pharmacokinetics (PK) of tacrolimus is influenced by a single nucleotide polymorphism within intron 3 of cytochrome P450 3A5 (CYP3A5). Patients who carry at least one CYP3A5*1 allele are considered to be CYP3A5 expressors (about 12% of the Caucasian population, Hapmap project) and thus require a 1.5 to 2-fold higher starting dose than CYP3A5*3/*3 carriers to reach the predefined target exposure early after transplantation. Although this polymorphism showed no impact on the performance of the Bayesian estimators previously developed for other tacrolimus formulation, the patient status for CYP3A5*3 will be considered in this pharmacokinetic study as a potential covariate in, or confounding factor of, the PK model. Specifically, owing to a 12% frequency in the White European population, about 4 patients carriers of the CYP3A5*1 allele are expected in this study; the performance of the PK model and Bayesian estimator developed will be specifically evaluated in this subgroup.
Cohort 1 To evaluate the pharmacokinetic interactions of CJ-12420 after multiple oral doses of CJ-12420 given alone or in combination with amoxicillin/clarithromycin in healthy subjects. Cohort 2 To evaluate the pharmacodynamic profiles of CJ-12420 after multiple oral doses of CJ-12420 in combination with amoxicillin/clarithromycin in healthy subjects as compared to an active control group, i.e., pantoprazole in combination with amoxicillin/clarithromycin.
The purpose of this study in healthy people is to investigate the safety, toleration and time course of UK-396,082 concentration in the blood and any changes in relevant markers of drug effects, following multiple doses given twice daily by mouth for 14 days.
Diabetes mellitus is a growing global disease now and future, and in China, 1.2 million peoples per year have been diagnosed as diabetes mellitus. 90% diabetes mellitus patient is Type 2 diabetes mellitus. Glipizide is a potent drug to service patients who suffer from Type 2 disease. Little information has been presented for the relationship between CYP2C19 genetic polymorphism and glipizide, since recently the investigators reported that there existed a tendency. In this study the investigators found that CYP2C19 polymorphism significantly influenced the pharmacokinetics of glipizide.
