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.
The purpose of this study is to compare the safety of two different dose regimens of unfractionated heparin (UFH) during a percutaneous coronary intervention (PCI) procedure in patients with UA (unstable angina)/NSTEMI (non ST segment elevation myocardial infarction) who have been initially treated with fondaparinux.
The primary objective of the study is to evaluate the efficacy of Quetiapine extended release (XR) in combination with an selective serotonin reuptake inhibitor (SSRI) or Venlafaxine versus Lithium in combination with an selective serotonin reuptake inhibitor or Venlafaxine versus Quetiapine extended release monotherapy in subjects with treatment resistant depression as assessed by the changes from randomisation to week 6 in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score. As an independent objective, the primary objective will also be evaluated in two subgroups of patients: (1) patients who were resistant to two previous antidepressant therapies and (2) in the subgroup of patients with one previous failure.
This study will evaluate efficacy and safety of nilotinib versus imatinib in adult patients with unresectable or metastatic gastrointestinal stromal tumors (GIST).
This study is being conducted in order determine whether IMA910 as single agent with GM-CSF as adjuvant following pre-treatment with low-dose cyclophosphamide is safe and shows sufficient anti-tumour effectiveness in patients with advanced CRC to warrant further development. Secondary objectives of this study are investigation of immunological parameters and additional effectiveness endpoints. Furthermore, safety, immunological parameters and effectiveness of IMA910 as single agent with GM-CSF in combination with imiquimod following pre-treatment with low-dose cyclophosphamide will be investigated in a 2nd cohort of patients. The regular study duration for individual patients in the 1st and 2nd cohort comprises regularly 18-42 days of screening (excluding HLA-typing), 33 weeks of treatment (16 vaccinations) and 4 weeks follow-up. Thus, the period between start of screening and end of trial is about 10 months per patient. Patients will be followed for response to subsequent treatments (chemotherapies with or without targeted agents) and survival every 2 months after EOS visit until death. Patients in the 1st and 2nd cohort will be withdrawn from study treatment once a progress according to RECIST is noted. An enrolment plan for the first 6 patients included into the 1st cohort will be part of this study to ensure maximum safety of the study participants. The enrollment of the first 6 patients into the 2nd cohort will also follow an enrolment plan to ensure maximum safety.
This is a global, multicenter, open-label safety extension study. Participants receiving single-agent trastuzumab emtansine or trastuzumab emtansine administered in combination with other anti-cancer therapies in a Genentech / Roche-sponsored parent study who are active and receiving benefit at the closure of parent study are eligible for continued treatment in this study.
This study is to demonstrate the safety and efficacy profile, in two different dose regimens of Edoxaban (DU-176b), (an investigational new drug being tested for the prevention of stroke/systemic embolic events (SEE)), in individuals with atrial fibrillation. Patients will be randomized to one of three treatment groups: High Dose Regimen, Low Dose Regimen, & Warfarin. The expected duration of the study is 24 months.
This is a study of an experimental drug (neratinib) versus a combination of drugs (lapatinib and capecitabine) in women who have erbB-2 (HER-2) positive metastatic or locally advanced breast cancer. The goal of this study is to compare the two regimens in shrinking tumors and extending the lives of women with erbB2 (HER2) positive breast cancer. The study will also compare the safety of the two regimens and to compare quality of life of patients taking the two regimens.
This is a study to determine the safety and tolerability of 28 days of daily dosing of two doses (280 mg and 560 mg) of Arikayce™ versus placebo in patients who have bronchiectasis and chronic infection due to Pseudomonas infection.
Evaluation of the safety and efficacy of Oxcarbazepine XR as adjunctive treatment for adults with partial onset seizures
The present study is assessing the efficacy and safety of AVE5530 (25 mg and 50 mg) in add-on to ongoing treatment with high doses of statin in a double-blind manner in comparison with placebo, in the management of patients with severe primary hypercholesterolemia considered as inadequately controlled despite their ongoing statin treatment. The main objective is to evaluate the effects of the association AVE5530+statin on LDL-C level reduction after 12 weeks of treatment. The effects of AVE5530 on other lipid parameters will be assessed as secondary objectives.
