There are about 21071 clinical studies being (or have been) conducted in Spain. 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.
This is a prospective trial of random distribution, open, parallel group, in which patients with esophagic variceal bleeding will be randomized into two treatment groups, after controlling acute bleeding. All patients received standard medical therapy with b-blockers and endoscopic ligation (LEV) of esophageal varices. The control group will be assigned to receive LEV + Nadolol + MNI. The experimental group will be assigned to receive treatment according to the hemodynamic response. All patients included in the experimental group received LEV and pharmacological treatment nadolol alone or combined with MNI or Prazosin (PZ)
Observational study about the incidence of relative adrenal insufficiency in patients with cirrhosis and acute variceal bleeding; in patients with acute peptic gastrointestinal bleeding and without liver disease; and in patients with severe acute pancreatitis. This is a study using pharmaceutical specialties in the approved conditions of use.
The purpose of this study is to determine the pathological complete response rate of addition of bevacizumab to induction therapy (xelox) and concomitant treatment (capecitabine+radiotherapy), followed by surgery.
Soft tissue sarcomas (STS) are an uncommon group of malignant tumors of mesenchymal origin. For most advanced STS types, chemotherapy is currently the only available treatment. Unfortunately, a very limited number of useful drugs are active against this disease. Doxorubicin is widely considered the standard first-line treatment. Ifosfamide has also a well-established activity (1,2) and is often administered either associated with Doxorubicin or alone as a second-line chemotherapy treatment. Other drugs such as DTIC, Gemcitabine and Temozolomide showed modest activity as a second-line agents (3,4). Thus, there is a necessity to identify new agents with activity to improve therapy for patients with advanced STS. In some studies, most STS showed VEGF expression, and elevated serum VEGF levels were found to correlate with higher histologic tumor grade (5,6). Additionally, inhibition of VEGFR was associated with tumor activity in preclinical models of sarcoma (7,8). For these reasons, inhibition of VEGFR seems to be a reasonable approach to explore in the treatment of STS. Sorafenib (BAY 43-9006) is an orally available, small molecule multi-kinase inhibitor of VEGFR, PDGFR and RAF with demonstrated activity in the treatment of renal cell cancer (9). Preclinical studies suggest that the combination of Sorafenib with cytotoxic agents results in additive anti-tumor activity (10), initiating justification for combination studies. A recent trial, however, reported an unexpected incidence of cardiac toxicity in patients with STS treated with Bevacizumab, a monoclonal antibody that binds VEGF, in combination with Doxorubicin (11). This finding suggest that the possibility of potentiation of the cardiotoxicity of Doxorubicin when inhibiting the VEGF pathway cannot be ruled out. The association of Sorafenib with Ifosfamide, the other established active agent against STS, could improve the efficacy of single-agent Ifosfamide minimizing the risk of cardiac toxicity .
Poor prognosis follicular lymphoma patients have an estimated median overall survival of 5-6 years. The proposed trial offers life-time idiotypic vaccination to all such patients in first relapse/progression who will achieve second (first, in the case of patients who have never achieved complete response following standard first-line treatment) complete response through autologous stem cell transplant prior to vaccination start. The ultimate goal is a cure, defined as a vaccine-maintained complete response lasting both at least 10 years and at least twice as long as each patient's first complete response.
To compare the sustained virological response (SVR = ribonucleic acid (RNA) - hepatitis C virus (HCV) undetectable at week 24 before end the treatment) in chronic hepatitis C patients genotype 1-4 co-infected with HIV-HCV, treated with Peginterferón alfa-2a (40 KD) 180 µg/week and Ribavirin (2000 mg/day during 4 weeks, follow of 1000-1200 mg/day, according to body weight); versus Peginterferón alfa-2a (40 KD) 180 μg/week and Ribavirin (1000-1200 mg/day, according to body weight). To evaluate the impact to extend the treatment with Peginterferon alfa-2a and Ribavirin to week 72, in SVR of these patients with genotypes 1-4 without rapid virological response (RVR = RNA - HCV undetectable at 4 week).
There is some evidence for a hypercoagulable state in sleep apnea-hipopnea syndrome (SAHS), which could play a role in the increased cardiovascular morbility and mortality. Respiratory alterations (hypoxia, hypoxia- reoxygenation) and sleep fragmentation that these patients suffer during the sleep may induce modifications in clotting-fibrinolisis factors that may be a risk factor for venous thromboembolism (VTE). OBJECTIVES:To calculate and compare the prevalence of sleep apnea-hipopnea syndrome in patients with venous thromboembolism with a gender, aged and BMI matched control group. Assessment of the association between SAHS and other risk factors for VTE. To compare clotting- fibrinolisis patterns, sleep parameters, blood pressure and pulmonary arterial obstruction index in patients with SAHS and VTE and those ones without SAHS.
The aim of this study is to assess the efficacy of caffeine compared to placebo as a maintenance treatment for cocaine dependence. Caffeine potentiation with biperiden will be also studied. Ninety patients with snorted/sniffed cocaine dependence will be randomized to receive caffeine (300 - 1200 mg t.i.d.) plus biperidene (8 mg b.i.d.) caffeine (300 - 1200 mg t.i.d.) with placebo or placebo during 10 days in an in-hospital setting.
The triage of patients with suspected acute coronary syndrome in the emergency room is a time-consuming diagnostic challenge. Therefore high sensitive early markers for myocardial damage are needed for more rapidly rule out of acute myocardial infarction (AMI) - especially for the first 3 to 4 hours after onset of chest pain in AMI ("troponin-blind" period). Therefore we test the hypothesis that the use meticulous patient history and novel cardiac markers can provide a faster detection or exclusion of AMI in patients presenting with acute chest pain to the emergency department. The prospective cohort study is designed to enrol patients presenting with acute chest pain at rest within the last 12 hours to the emergency department. Several blood samples for detection of the new markers will be drawn and compared with the gold standard for the diagnosis of AMI (high-sensitivity cardiac troponin T). All patients will be contacted by telephone at 3, 12, 24 and 60 months to determine functional status, major adverse cardiac events (death, myocardial infarction, coronary artery bypass grafting, percutaneous coronary intervention), and the results of cardiac examination (stress test, coronary angiography) if performed.
