Maraviroc (UK-427,857), a selective and reversible CCR5 co-receptor antagonist, has been shown to be active in vitro against a wide range of clinical isolates (including those resistant to existing classes). In HIV-1 infected patients in the United States, maraviroc (UK-427,857) is approved for use as part of combination antiretroviral treatment in treatment-experienced and treatment-naive adult subjects. At least 50% of treatment-experienced patients are infected with R5-tropic HIV-1 exclusively. However, even in patients infected with a dual tropic (R5 + X4) phenotype, a large proportion of the virus population still uses CCR5 exclusively. Thus, the purpose of this study is to evaluate the antiretroviral activity, and safety, of maraviroc (UK-427,857) (in combination with other agents) in HIV infected, treatment experienced patients who are failing their current antiretroviral regimen and not infected with R5-tropic virus exclusively. This study will involve more than 200 centers globally to achieve a total randomized subject population of 192 subjects. Patients will be randomly (1:1:1) assigned to one of three groups: Optimized Background Therapy [OBT (3-6 drugs based on treatment history and resistance testing)] + maraviroc (UK-427,857) 150 mg taken once daily, OBT + maraviroc (UK-427,857) 150 mg taken twice daily, or OBT alone. Randomization was stratified by Enfuvirtide use in OBT (yes/no) and Screening HIV-1 RNA level (viral load) (<100,000/≥ 100, 000 copies per milliliter [copies per mL]). The study will enroll over approximately a 9 month period with 48 weeks of treatment. Physical examinations will be performed at study entry, weeks 4, 8, 12, 16, 20, 24, 32, 40 and 48. Blood samples will also be taken at study entry, weeks 2, 4, 8, 12, 16, 20, 24, 32, 40, and 48. Additionally, blood samples will be drawn twice, at least 30 minutes apart, at weeks 2 and 24 for maraviroc (UK-427,857) pharmacokinetic analysis. As part of this clinical study a blood sample will also be taken for non-anonymized pharmacogenetic analysis. Patients will undergo a 12-lead electrocardiogram at study entry, weeks 24 and 48.
Maraviroc (UK-427,857), a selective and reversible CCR5 coreceptor antagonist, has been shown to be active in vitro against a wide range of clinical isolates (including those resistant to existing classes). In HIV-1 infected patients, maraviroc (UK-427,857) given as monotherapy for 10 days reduced HIV-1 viral load by up to 1.6 log, consistent with currently available agents. Safety and toleration have been studied in over 400 subjects for up to 28 days at 300 mg twice daily. No significant effects were seen on the QTc interval. The purpose of this study is to evaluate the antiretroviral activity of maraviroc (UK-427,857) in HIV infected, treatment experienced patients who are failing their current antiretroviral regimen and infected with R5-tropic virus exclusively. This study will involve more than 100 centers in Europe and Australia to achieve a total randomized subject population of 500 subjects. Patients will be randomly (2:2:1) assigned to one of three groups: Optimized Background Therapy [OBT (3-6 drugs based on treatment history and resistance testing)] + maraviroc (UK-427,857) 150 mg taken once daily, OBT + maraviroc (UK-427,857) 150 mg taken twice daily, or OBT alone. The study will enroll over approximately a 9 month period with 48 weeks of treatment. This may be extended for an additional year depending on the results at 48 weeks. Physical examinations will be performed at study entry, weeks 4, 8, 12, 16, 20, 24, 32, 40 and 48. Blood samples will also be taken at study entry, weeks 2, 4, 8, 12, 16, 20, 24, 32, 40 and 48. Additionally, blood samples will be drawn twice, at least 30 minutes apart, at weeks 2 and 24 for maraviroc (UK-427,857) pharmacokinetic analysis. As part of this clinical study a blood sample will also be taken for non-anonymized pharmacogenetic analysis. Patients will undergo a 12-lead electrocardiogram at study entry, weeks 24 and 48.
RATIONALE: Drugs used in chemotherapy, such as amifostine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well amifostine works in treating young patients with newly diagnosed de novo myelodysplastic syndromes.
Maraviroc (UK-427,857), a selective and reversible CCR5 coreceptor antagonist, has been shown to be active in vitro against a wide range of clinical isolates (including those resistant to existing classes). In HIV-1 infected patients, maraviroc (UK-427,857) given as monotherapy for 10 days reduced HIV-1 viral load by up to 1.6 log, consistent with currently available agents. Safety and toleration have been studied in over 400 subjects for up to 28 days at 300 mg twice daily. No significant effects were seen on the QTc interval. The goal of this study is to compare the safety and efficacy of maraviroc (UK-427,857) versus efavirenz, when each are combined with two other antiretroviral agents, in patients who are previously naive to antiretroviral therapy. This study will involve approximately 200 centers from around the world to achieve a total randomized subject population of 1071 subjects. Patients will be randomly assigned to one of three groups: maraviroc (UK-427,857) 300 mg once daily added to zidovudine/lamivudine (300 mg/150 mg twice daily), Maraviroc (UK-427,857) 300 mg twice daily added to zidovudine/lamivudine (300 mg/150 mg twice daily) or efavirenz (600 mg once daily) added to zidovudine/lamivudine (300 mg/150 mg twice daily). The study will enroll over approximately an 18 month period (5 months Phase 2b run-in, 13 months Phase 3) with 96 weeks of treatment. This may be extended for an additional 3 years depending on the results at 96 weeks. Physical examinations will be performed at study entry, weeks 4, 8, 12, 16, 20, 24, 32, 40, 48, 60, 72, 84 and 96. Blood samples will also be taken at study entry, weeks 2, 4, 8, 12, 16, 20, 24, 32, 40, 48, 60, 72, 84 and 96. Additionally, blood samples will be drawn twice, at least 30 minutes apart, at weeks 2 and 48 for maraviroc (UK-427,857) pharmacokinetic analysis. As part of this clinical study a blood sample will be taken for non-anonymized pharmacogenetic analysis. Patients will undergo a 12-lead electrocardiogram at study entry, weeks 24, 48 and 96. A computerized tomography (CT) scan will also be performed, at selected centers, at study entry and week 96. Patients will be asked to complete a symptom distress questionnaire at study entry, weeks 12, 24, 48 and 96.
The study is designed to evaluate whether Neoral dose optimization together with a therapeutic drug monitoring of Certican will prevent renal dysfunction as observed in the pivotal cardiac trial while maintaining the efficacy. This objective will be assessed by comparing renal function post-transplant between 2 groups of patients.
PI-88 is a new experimental drug that inhibits tumour growth by reducing the formation of new blood vessels into tumours. Docetaxel is a standard second-line treatment offered to patients with non-small-cell lung cancer who haven't responded to first-line therapies (platinum-based drugs or radiotherapy). Of this group of patients, only 20% remain progression-free 6 months after starting docetaxel treatment. The PR88202 study has been designed to compare two different cancer treatments (docetaxel only, and docetaxel plus PI-88) and to work out which is more effective against the cancer. It is hoped that the combination of PI-88 with docetaxel will allow patients to extend the time it takes for their disease to progress, and also to improve their quality of life.
The goal of this study is to determine the effectiveness and safety of an annual intravenous treatment of zoledronic acid for the treatment of osteoporosis in men. All patients will receive calcium and vitamin D supplements.
This study is a test of the safety and effectiveness of two drugs, one for diabetes and one for hypertension, in keeping patients with high lab values of glucose from progressing to frank diabetes and developing cardiovascular complications. People in this study cannot have frank diabetes but are considered "borderline" based on blood tests. People in the study take none, one or both of the drugs and do not know which one(s) they are taking.
The VITATOPS study is a multi-center, randomized, double blind, placebo-controlled secondary stroke prevention trial to determine whether the addition of vitamin supplements (B12 500 ug, B6 25 mg, Folate 2 mg) to best medical/surgical management (including modification of risk factors) will reduce the combined incidence of recurrent vascular events (stroke, myocardial infarction) and vascular death in patients with recent stroke or transient ischemic attack (TIA). All patients presenting to one of the participating neurologists or general physicians within seven months of stroke (ischemic or hemorrhagic) or TIA (eye or brain) are eligible for this trial. Eligible patients will be randomized in a double-blind fashion to receive multi-vitamins or placebo, 1 tablet daily. The primary outcome event is the composite event "stroke, myocardial infarction, or death from any vascular cause", whichever occurs first. Our target is to recruit a total of 8,000 patients over the next two years with a median follow-up of 2.5 years. Recruitment to the trial began in November 1998 and is planned to continue until December 2005. We aim to complete final follow-up by the end of 2006. However, the Steering Committee will be flexible in dictating the need for ongoing recruitment and continuing follow-up, depending on the overall rate of the primary outcome event in the entire cohort at each interim analysis.
