Pilot study designed to characterize the plasma caffeine pharmacokinetic profile of encapsulated caffeine when consumed in the fasted and fed states.
Chronic myeloid leukemia (CML) consists of 3 clinical stages including chronic phase, accelerated phase and blast crisis. Patients may only survive for few more days to weeks once the disease progresses to blast crisis, even though they might have been stable for several years in the chronic phase. The standard treatment, continuous use of tyrosine kinase inhibitors (TKIs), improves long-term survival, and even may help patients achieve complete remission. Four TKIs are reimbursed by National Health Insurance in Taiwan. Among them, imatinib, nilotinib as well as dasatinib, and ponatinib are the first, second and third generations of TKIs, respectively. Many factors influence the disease control of CML, such as TKI type, genetic mutation and medication adherence. Only 69% of patients followed their physicians' recommendations in a local survey. The medication adherence of TKIs was compromised based on several clinical studies domestically and worldwide due to the slow progression in the chronic phase. Patients might hold or decrease the dose of TKIs on their own when they suffer side effects. Furthermore, the significant intra-subject variations of TKI plasma concentration and drug-drug and drug-food interactions which alter the metabolism of TKIs may lessen therapeutic effect and patient safety. Therefore, this study aims to develop and validate analytic methods of imatinib, dasatinib, nilotinib and ponatinib plasma concentrations. The investigators plan to build the pharmacokinetic models of these 4 TKIs and analyze the impacts of meals, adherence, hepatic enzyme inhibitors and inducers, antacids, proton pump inhibitors and H2 blockers, etc. Adverse drug reactions and treatment outcomes will be evaluated to determine the availability and feasibility of therapeutic drug monitoring of TKIs as part of routine service in pharmacist-led clinics.
Combination treatment with baclofen and chlorzoxazone (CHZ) is under investigation for the treatment of spinocerebellar ataxia types 1 and 2. Achievement of therapeutic benefit with this combination approach requires that effective concentrations of both agents reach the systemic circulation, and ultimately reach the intended pharmacologic target. This in turn requires understanding of the clinical pharmacokinetic properties of both drugs when administered individually, as well as knowledge of the extent to which the agents might interact when given concurrently. Study Objectives: 1. To evaluate the pharmacokinetic properties of baclofen and CHZ when administered as individual entities at separate times, using customary clinical doses. 2. To compare the pharmacokinetic properties, and assess the bioequivalence, of each drug administered separately compared to administration of the two drugs concurrently. 3. To assess adverse events attributed to the two drugs when administered separately or together.
Preoperative antimicrobial prophylaxis is a key element for the prevention of surgical site infection, the most common type of nosocomial infection in surgical patients. Prophylactic antibiotics are selected depending on the type of surgery, and first- or second-generation cephalosporins have been mainly used. Cefoxitin, a second-generation cephalosporin with anaerobic activity, has been used in various clinical settings as a prophylactic antibiotic for colorectal surgery. Cefoxitin is generally dissolved in normal saline and intravenously administered for a short time of 5-10 minutes before skin incision. However, there are several drawbacks to the current dosing strategy. First, the dose of cefazolin is determined by a "rule of thumb", and there is controversy over whether 1 g or 2 g is appropriate, with the opinion that 2 g being more appropriate prevailing. Second, the standard administration method unnecessarily induces a concentration higher than the concentration required to prevent surgical site infection. Third, significant covariates that can affect the maintenance of MIC during surgery are not considered. The target-concentration controlled infusion (TCI) method can be a viable alternative administration method for antibiotics. The TCI method enables individual customized administration according to the covariates (i.e., weight, creatinine clearance) included in the pharmacokinetic parameters; also, although with some variability, the drug can be administered while maintaining the target concentration. The aim of this study was to evaluate the effectiveness of administering cefoxitin in patients undergoing colorectal surgery with a syringe pump equipped with a target concentration control injection function
This is an open-label, randomized, single-dose, three treatment, three-period crossover study comparing the test and reference products under fasted or fed conditions (as applicable). In one period of the study, PrimeC-ER tablets will be administered to subjects following an overnight fast of at least 10 hours. In a second period of the study, PrimeC-ER tablets will be administered to subjects at 30 minutes following the start of a standardized high-fat, high-calorie breakfast that was preceded by an overnight fast of at least 10 hours. In a third period of the study, a single 750 mg dose of ciprofloxacin and a single 200 mg dose of celecoxib will be co-administered to subjects following an overnight fast of at least 10 hours. The order of administration will follow a six-sequence randomization schedule. Blood samples will be collected at pre-dose and at intervals over 48 hours after dosing in each study period. Subjects will be confined at the clinical facility from at least 10.5 hours before dosing until 48 hours after dosing in each study period. The interval between doses will be at least 7 days. Subjects will return to the clinical facility 7 days (± 1 day) after the last study drug administration for an end-of study follow-up visit.
This is a phase 1 single-center study to assess the pharmacokinetics (PK), safety and tolerability of KT07 capsules in healthy adult subjects. This study consists of 2 parts: Part 1 and Part 2. The primary objectives of Part 1 include selection of suitable PK markers for bioanalysis, development and validation of GLP bioanalytical methods for follow-up PK studies, assessment of PK of potential markers following an oral administration of KT07, and provision of PK sampling strategy for Part 2. The primary objective of Part 2 is to evaluate the PK profile following a single dose and multiple doses in healthy adult subjects.
Randomized, double-blind and placebo-controled study to assess the safety, tolerability and pharmacokinetics of single ascending doses of ZX-7101A and its food effect in China healthy adult volunteers. The study is composed of 2 parts. Part 1 is to assess the safety, tolerability and pharmacokinetics of a single ascending doses of ZX-7101A tablet. Part 2 is to assess the food effect on ZX-7101A at a selected dose in a cross-over design.
