There are about 1560 clinical studies being (or have been) conducted in Serbia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Corlux (mifepristone) is a new medication that modulates the body's use of a hormone called cortisol. Under normal conditions, cortisol and other hormones are created by the body in response to physical and emotional stress, triggering a healthy stress response. People who suffer from psychotic major depression may have unusually high levels of cortisol circulating within them or abnormal patterns of cortisol levels, overloading the stress response mechanism and causing symptoms of psychosis such as delusional thoughts or hallucinations. If Corlux can keep the body's cortisol receptors from being overloaded, the stress response system may return to normal function, which may result in improvement of symptoms. The purpose of this study is to allow patients who have already participated in an earlier 8 week study of Corlux versus placebo (an inactive pill) to receive additional courses of treatment with Corlux periodically if a psychotic episode should reappear during a period of one year.
To determine whether the administration of test article will decrease the occurrence of ventricular arrhythmias in patients who have acute coronary syndrome (unstable angina, ST segment elevated myocardial infarction or myocardial infarction without ST elevation).
RATIONALE: Drugs used in chemotherapy, such as cytarabine and VNP40101M, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. PURPOSE: This randomized phase III trial is studying cytarabine and VNP40101M to see how well they work compared to cytarabine alone in treating patients with relapsed acute myeloid leukemia.
This 2 arm study will assess the safety and efficacy of tocilizumab monotherapy versus methotrexate in patients with active rheumatoid arthritis (RA). Patients will be randomized to receive tocilizumab 8mg/kg iv every 4 weeks plus placebo po weekly, or methotrexate 7.5-20mg po weekly plus placebo iv every 4 weeks. The anticipated time on study treatment is 3-12 months and the target sample size is 500+ individuals.
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.
The purpose of the study is to evaluate whether the time to progression for the DOXIL and docetaxel combination therapy group was superior to that of the group treated with docetaxel monotherapy in participants with advanced breast cancer.
The purpose of this study is to demonstrate efficacy and safety of quetiapine fumarate (SEROQUEL) compared with placebo in the treatment of adolescent patients with schizophrenia.
The primary purpose of this study is to determine whether abetimus sodium is more effective than placebo in delaying time to renal flare in SLE patients with a history of renal disease.
This 2 arm study will assess the efficacy and safety of intermittent oral Xeloda, or iv fluorouracil/leucovorin, in combination with intravenous Eloxatin (oxaliplatin) in patients previously treated for metastatic colorectal cancer. Patients will be randomized to receive either 1)XELOX (Xeloda 1000mg/m2 po bid on days 1-15 + oxaliplatin) in 3 week cycles or 2) FOLFOX-4 (oxaliplatin + leucovorin + 5-FU in 2 week cycles. The anticipated time on study treatment is until disease progression, and the target sample size is 500+ individuals.
RATIONALE: Drugs used in chemotherapy, such as mitomycin, fluorouracil, and cisplatin, use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells. It is not yet known whether radiation therapy and mitomycin are more effective when combined with fluorouracil or with cisplatin in treating anal cancer . PURPOSE: This randomized phase II/III trial is studying how well giving radiation therapy and mitomycin together with fluorouracil works compared to radiation therapy, mitomycin, and cisplatin in treating patients with locally advanced anal cancer.
