Filter by:This is a phase 1 study to assess the routes of elimination of a single oral dose of [14C] PF-00868554 and to characterize the metabolic profile following single dose administration.
The objectives are: to compare the oral bioavailability and plasma pharmacokinetics of TMC435350 for 2 different solid formulations to those of TMC435350 formulated as a powder blend in a capsule, after a single oral dose of 200 mg in healthy volunteers; to determine the short term safety and tolerability of TMC435350 after a single oral dose of 200 mg formulated in capsules with 2 different formulations and as a tablet in healthy volunteers
The purpose of this study is to evaluate the safety and tolerability of three different doses of TMC435350 compared to placebo in healthy Japanese males.
The purpose of this study is to assess the interactions seen when somebody doses with TMC435350 and Rifampin (commercial form of antibiotic).
This study will determine if Albumin-linked interferon (Albinterferon alfa-2b) every 2 weeks is safe and tolerated by patients infected by both hepatitis C virus (HCV) and human immunodeficiency virus (HIV). This is a new medication developed for HCV. It may help the immune system fight infections, especially those caused by viruses. Albinterferon alfa-2b appears quite similar to other interferons, in side effects and action in controlling HCV. Patients ages 18 and older who are infected with HCV genotype 1, are HIV positive, are infected with HCV, and have evidence of HCV-induced liver disease; and who are not pregnant or breast feeding may be eligible for this study. Many visits to NIH over a 76-week period are required. There will be collection of blood and urine, pregnancy test, and tests of HCV in the blood. A liver biopsy is required before start of the study if patients have not had one within 1 year. Another is done at the end of 72 weeks. An eye exam is done before start of the study and repeated later. An optional procedure called automated pheresis is done at the study beginning. Researchers can study patients' immunity to control HCV. Blood is drawn through a needle in an arm vein and spun in a machine to separate the desired blood component. Remaining blood is returned to the patient. Patients will receive Albinterferon alfa-2b at a dose of 900 mcg every 2 weeks for 48 weeks, by injection under the skin. Ribavirin is given at 1,000 mg or 1,200 mg by mouth twice daily, depending on a patient's weight. Side effects of Albinterferon alfa-2b are fatigue, headache, joint and muscle pain, and sleeplessness. The major side effect of ribavirin is anemia. Visits ranging from week 3 to 44 will determine the safety of Albinterferon alfa-2b and ribavirin and to see effects on reducing the HCV viral load. For weeks 48, 52, 56, 64, 72, and 76, patients will return for a clinic visit and blood tests. At week 72, an abdominal ultrasound and liver biopsy are done. Week 76 includes discussion of biopsy results.
