The purpose of this research study is to understand whether there is any difference in the amount of tasimelteon (including its breakdown product) in the blood when taken alone and in combination with either rifampin or ketoconazole. Cytochrome P450 3A4 is an important enzyme produced by the body to breakdown certain medications. In this study, the effect that this important enzyme has on tasimelteon is being studied by assessing the effect rifampin and ketoconazole have on tasimelteon and how they are broken down by your body. Rifampin is a known inducer of Cytochrome P450 3A4 enzyme meaning that it increases the activity of the enzyme. Ketoconazole is a known inhibitor of Cytochrome P450 3A4 enzyme meaning that it decreases the activity of the enzyme. In addition, the safety and tolerability of tasimelteon will also be assessed throughout the study.
The purpose of this study is to assess the pharmacokinetic interaction of multiple-dose ketoconazole on single-dose YM178 OCAS and the safety and tolerability of YM178 OCAS alone and in combination with ketoconazole in healthy adult volunteers.
GSK2118436 is an orally administered, potent and selective small molecule BRAF inhibitor that is being developed for the treatment of BRAF mutation-positive tumors. This is a 4-part study (in 4 separate cohorts of subjects) designed to examine the interaction potential of GSK2118436, either as a perpetrator (i.e., effect of GSK2118436 on warfarin; Part A) or victim (i.e., effect of other drugs on GSK2118436; Part B: ketoconazole and Part C: gemfibrozil), as well as to evaluate the single and repeat dose pharmacokinetic parameters of GSK2118436 (Part D). A sufficient number of subjects will be screened to obtain approximately 12 evaluable subjects each for Part A, Part B, Part C and Part D. Following completion of this study, subjects may continue dosing with GSK2118436 in the roll-over study, Protocol BRF114144.
The purpose of this study is to determine how dosing with ketoconazole (Nizoral) or esomeprazole (Nexium) affects the pharmacokinetics of oral pazopanib. The study will also test for safety of pazopanib when administered with ketoconazole or esomeprazole.
Ketoconazole is a potent inhibitor of the cytochrome P450 (CYP) 3A4 enzyme system, one of the enzyme systems responsible for the metabolism of colchicine. This study will evaluate the effect of multiple doses of ketoconazole on the pharmacokinetic profile of a single 0.6 mg dose of colchicine. A secondary objective is to evaluate the safety and tolerability of this regimen in healthy volunteers. All study subjects will be monitored for adverse events throughout the study period.
This study is being conducted to examine the effect of three CYP3A4 inhibitors (ketoconazole, erythromycin and ritonavir) on the single dose pharmacokinetics of avanafil. Ketoconazole and ritonavir are potent inhibitors of CYP3A4 and erythromycin is a moderate CYP3A4 inhibitor. Any interaction that is observed would be predictive of other inhibitors of CYP3A4.
The purpose of this research study is to evaluate the effect of several daily doses of ketoconazole (a medication used to treat fungal infections like athlete's foot) on a single dose of GSK189075 (an experimental diabetes drug), and also to evaluate the safety and tolerability of GSK189075 in healthy volunteers. The study will see whether ketoconazole causes GSK189075 to stay in your bloodstream for a longer period of time. It will also examine whether GSK189075 causes any changes in the amount of glucose you have in your urine.
This is a two period study of healthy adult subjects to characterize the effect of the dosing of ketoconazole on the the way the body reacts to a dose of GW679769, and to assess the safety profile of oral casopitant with and without ketoconazole. This study will consist of a screening period, two treatment periods and a post-treatment follow-up visit.
This study will determine the maximum dose of docetaxel that can be given safely in combination with ketoconazole for treating advanced prostate cancer. Docetaxel is approved for the treatment of several other types of cancers; ketoconazole is an approved antifungal medication that is also commonly used in high doses to treat prostate cancer. Patients 18 years of age and older with advanced prostate cancer that does not respond to hormone therapy may be eligible for this study. Candidates will be screened with blood tests to evaluate liver, kidney and other organ function and with x-rays, scans, or other imaging tests to determine the extent of disease. Participants will take the following medications: * Docetaxel daily, infused through a vein over 30 minutes, in 4-week cycles-3 consecutive weeks of drug followed by one week of rest * Dexamethasone, 12 hours and 1 hour before and 12 hours after docetaxel infusions to help prevent fluid retention caused by the docetaxel * Ketoconazole, 3 times a day * Hydrocortisone, twice a day to replace a loss of natural steroids caused by the ketoconazole Patients will be hospitalized 1 to 2 days each for the first and second doses of docetaxel to allow for frequent blood draws to measure blood levels of the drug. Ketoconazole will be started about 2 weeks after the first dose of docetaxel and the second dose of docetaxel will be given 2 days after that. In order to determine the maximum tolerated dose of docetaxel, the first few patients in the study will be given a low dose of the drug, and subsequent patients will get increasingly higher doses until unacceptable side effects occur. Because prostate cancer cells may grow if exposed to testosterone, patients may have to have their testosterone production suppressed either surgically (removal of the testicles) or medically with an injection of leuprolide or goserelin, which are luteinizing hormone-release hormone agonists that reduce the amount of testosterone. Imaging studies, such as x-rays, bone scans or computed tomography (CT) scans, will be done about every 3 months to examine how the tumor is responding to therapy. After six treatment cycles, patients will have monthly chest x-rays to check for fluid around the lining of the lungs, which may occur as a result of docetaxel therapy. Treatment is expected to continue for at least 3 to 6 months, although this time could be shortened or extended depending on the tumor response to therapy or side effects of the drugs. Patients who do not experience bad side effects and whose tumor does not grow during the first 3 treatment cycles will continue treatment; those who experience unacceptable side effects will be taken off the study. ...
