There are about 2700 clinical studies being (or have been) conducted in Bulgaria. 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.
Picoplatin is a new type of platinum drug that has been investigated in several clinical trials, and may provide an improved safety profile over current treatment options. This study is designed to compare the efficacy and safety of picoplatin plus Best Supportive Care (BSC) with BSC alone. Best Supportive Care includes care and treatment to optimize the comfort of patients and their ability to function, as well as to minimize the side-effects of anti-cancer treatments.
The purpose of this study is to explore tolerability, safety and effectiveness of flexibly dosed paliperidone extended release (ER) in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self) previously unsuccessfully treated with an oral antipsychotic medication.
The purpose of the study is to evaluate the safety and efficacy of FOLFIRI (Irinotecan, Leucovorin and 5 Fluorouracil) chemotherapy when combined with sunitinib or FOLFIRI chemotherapy without adding sunitinib as the first line treatment of patients with metastatic colorectal cancer.
The purpose of this study was to evaluate the long term safety and tolerability of peginesatide for the maintenance of hemoglobin in participants with chronic kidney disease (CKD) who had received at least 24 weeks of peginesatide treatment in an earlier study.
The primary objective is to compare the time to progression (TTP) of three daily doses of thalidomide (100, 200 and 400 mg) with high-dose dexamethasone in relapsed refractory multiple myeloma (MM) patients and to subsequently select the optimum thalidomide dose in terms of median TPP and toxicity.
To determine if treatment with BG00012 can decrease the number of MS relapses during a certain time period. Other goals of the study are to determine if, over time, BG00012 treatment can decrease the number of certain types of brain lesions commonly seen in MS patients and slow down the time it takes for MS to get worse. Other objectives of the study are to determine the safety and tolerability of BG00012, as well as the effect it may have on tests and evaluations used to assess MS. Additionally, glatiramer acetate is being used to compare its benefits and risks with placebo and BG00012.
Benign Prostatic Hypertrophy (BPH) is a common and bothersome condition of aging men. It is characterized by an enlargement of the prostate occurring in human male over the age of 50 which increases in prevalence with age, and among those aged 50 to 80, about 40% report moderate or severe urinary symptoms of prostatism. The aim of treatment is to improve patients' quality of life which primarily depends on the severity of the symptoms of BPH. Current treatments of BPH have a benefit / risk ratio which leaves room for improvement. For this study, study medication (Cetrorelix pamoate or placebo) is administered by injection in the buttocks (Intramuscular). All patients completing the double-blind portion (Week 0 to 52) are eligible to receive the active drug during the open-label part of the study (Week 52 to 90).
This single arm study will assess the safety and efficacy of a regimen of Avastin plus a taxane, with or without additional chemotherapy, as first-line treatment in patients with locally recurrent or metastatic breast cancer. All patients will receive Avastin (10mg/kg iv every 2 weeks, or 15 mg/kg iv every 3 weeks) plus taxane-based chemotherapy. If taxanes are contraindicated, alternative chemotherapy (other than anthracyclines or pegylated liposomal doxorubicin) may be used. The anticipated time on study treatment is until disease progression, and the target sample size is 500+ individuals.
To evaluate the efficacy, safety, and tolerability of GSK372475 compared with placebo in the treatment of outpatient subjects with Major Depressive Disorder (MDD)
This 2 arm study will compare the efficacy and safety of continuation or discontinuation of Herceptin treatment in combination with 2nd line chemotherapy, in patients with HER2 positive metastatic breast cancer whose condition has progressed on 1st line chemotherapy plus Herceptin. Patients will be randomized either to continue or discontinue Herceptin treatment (6mg/kg iv infusion every 3 weeks) while receiving second-line chemotherapy of the investigator's choice. The anticipated time on study treatment is until disease progression, and the target sample size is 100-500 individuals.
