There are about 1062 clinical studies being (or have been) conducted in Latvia. 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 MADIT-II trial has shown that patients with severely reduced left ventricular ejection fraction (LVEF) post myocardial infarction benefit from the implantable cardioverter-defibrillator (ICD). However, retrospective analyses of the MADIT-II data have revealed a significantly increased morbidity and mortality in patients with appropriate ICD therapy: Appropriate ICD therapy is associated with 3.3-fold increased all-cause mortality, and the risk of a first heart failure hospitalization is 90% higher after 1st appropriate ICD therapy. Hence, the 1st appropriate therapy might indicate the necessity and utility of further clinical diagnostics and therapy in these patients. This trial is designed to (i) improve the knowledge of the group characteristics of patients suffering from 1st appropriate ICD therapy, (ii) but moreover to take additional therapeutic steps to reduce the mortality of this patient population.
Saxagliptin is a new investigational medication being developed for treatment of type 2 diabetes. This study is designed to test the efficacy of once daily saxagliptin in renally impaired patients.
To evaluate the efficacy and safety of fesoterodine in comparison to tolterodine and placebo for overactive bladder
First-line treatment of patients with locally recurrent or metastatic, HER2-negative breast cancer who have not received prior chemotherapy for locally recurrent or metastatic disease.
This 3 arm study assessed the efficacy of rituximab (MabThera®/Rituxan®) in the prevention of progression of structural joint damage in participants with active rheumatoid arthritis who had an inadequate clinical response to methotrexate. Participants were randomized to receive rituximab 500 mg intravenously (iv), rituximab 1000 mg iv, or placebo iv on days 1 and 15 every 24 weeks in the main study; all participants received concomitant methotrexate at a stable dose of 12.5-25 mg/week throughout the study. Further courses of rituximab were provided to eligible participants. Structural joint damage was assessed by magnetic resonance imaging (MRI) at baseline and at intervals during the study.
The purpose of the study is to test the efficacy of a vaccine against house dust mite and/or cat allergy compared to placebo in adult patients.
Two-arm, randomized, open-label trial designed to evaluate the efficacy and safety of bosutinib alone compared to imatinib alone in subjects newly diagnosed with chronic phase Chronic Myelogenous Leukemia (CML). The primary endpoint is cytogenetic response rate at one year.
This study will evaluate if extended therapy with oral rivaroxaban can prevent blood clots in the leg and lung that can occur with patients hospitalized for acute medical illness, and compare these results with those of the standard enoxaparin dose and duration regimen. The safety of rivaroxaban will also be studied.
This study was a Phase III, randomized, double-blind, placebo-controlled, multicenter international clinical trial conducted to investigate the use of pertuzumab in combination with trastuzumab and docetaxel as first-line treatment for participants with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC). Participants could have received one prior hormonal treatment for MBC. Participants may have received systemic breast cancer treatment in the neo-adjuvant or adjuvant setting, provided that the participant had experienced a disease-free interval (DFI) of greater than or equal to (≥)12 months from completion of adjuvant systemic treatment (excluding hormonal therapy) to metastatic diagnosis. Participants may have received trastuzumab and/or a taxane during the neo-adjuvant or adjuvant treatment. Participants were randomized in 1:1 ratio to receive either pertuzumab or placebo, along with trastuzumab and docetaxel once every 3 weeks (q3w), during the treatment phase of the study until investigator-assessed radiographic or clinical progressive disease, unmanageable toxicity, or study termination. Participants in the Placebo arm were not allowed to receive open-label pertuzumab after discontinuation from study treatment. However, if any analysis of overall survival had met the predefined criteria for statistical significance, participants in the Placebo arm still on treatment were offered the option to receive open-label pertuzumab in addition to other study medications.
The purpose of this study is to compare the safety and efficacy of zonisamide with placebo.
