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.
The purpose of the study is to evaluate the efficacy and safety of the capecitabine or 5-fluorouracil selection, according to polymorphisms in TS-3'UTR and ERCC1-118, to be combined with oxaliplatin or irinotecan as first-line chemotherapy in advanced colorectal cancer
The association of sleep apnea-hypopnea syndrome (SAHS) with the infections of the lower airway has not been studied. The aspiration of secretions of the upper airway and the colonization by microorganisms is considered a main event in most of the cases of community acquired pneumonia (CAP) , and specially in the nosocomial pneumonia. The silent aspiration to the lower airway is a common phenomenon in normal subjects during the sleep and some studies has reported that the patients with SAHS present an increase of the risk to pharyngeal aspirations. In fact, the presence of nasal and bronchial inflammation in patients with SAHS is a recognized event. The patients with SAHS could have a risk increased to develop pneumonia due to predisposition to the pharyngeal microaspiration to lower airways during the sleep and other mechanical factors associated. The prevalence of SAHS in patients with CAP could be increased as regards the data published for the same Spanish population. The presence of an apnea-hypopnea index (AHI) could be a risk factor not only to to CAP but to to present a unfavorable clinical evolution in comparison to patients with CAP with a normal AHI. The aim of this study will establish a relation between SAHS and the pneumonia risk.
This is a randomized, rater blinded trial in patients who interrupt treatment with natalizumab with or without being treated with other immunomodulatory drugs, or continue treatment with natalizumab. The main purpose of this study is to find out the following, when participants stop taking natalizumab for 24 weeks: - when MS symptoms return, and - if other drugs for MS may help control MS symptoms during the natalizumab-interruption period. This study will also explore how quickly the effects of natalizumab return after resuming natalizumab dosing.
This is a first-in-man, phase I clinical research study with BKM120, a potent and highly specific oral pan-class I phosphatidylinositol-3-kinase (PI3K) inhibitor. The study consists of a dose escalation part followed by a MTD expansion part. Once the MTD has been defined, the MTD expansion part will be opened for enrollment.
This study is designed to characterize the early effects of ApoA-I synthesis with RVX000222 on coronary atherosclerotic disease when administered to patients with coronary artery disease and have a low HDL-C level, as assessed by Intravascular Ultrasound (IVUS) in addition to standard background therapy.
The triple therapy darunavir/r + tenofovir/emtricitabine is likely to become a relevant first-line treatment option in the years to come. The dual combination of boosted darunavir + raltegravir is an innovative treatment option that combines two potent new antiretroviral drugs, one of which belongs to a new drug class (integrase inhibitor). The expected efficacy profile of this combination is promising. Moreover, this combination might have a better tolerance profile and has the advantage of sparing the NRTI class. In the context of tenofovir/emtricitabine currently being a reference backbone in first-line antiretroviral regimens, we hypothesise that, in combination with darunavir/r, raltegravir may be an alternative option if its efficacy is non-inferior to tenofovir/emtricitabine.
The objective of this study is to determine the efficacy of Traumeel S (both ointment and gel) compared to another antiinflammatory drug called Diclofenac in patients with a sprained ankle.
The purpose of this study is to determine any significant differences in the efficacy and acceptability between CitraFleet and Klean Prep® (polyethylene glycol) for the preparation of gastrointestinal subjects undergoing a colon examination.
Diabetic patients show an increased prevalence of non dipping arterial pressure pattern, target organ damage and elevated arterial stiffness. These alterations are associated with increased cardiovascular risk. The objectives of this study are the following: to evaluate the prognostic value of central arterial pressure and pulse wave velocity in relation to the incidence and outcome of target organ damage and the appearance of cardiovascular episodes (cardiovascular mortality, myocardial infarction, chest pain and stroke) in patients with type 2 diabetes mellitus.
Transbronchial lung biopsy (TBLB) is a bronchoscopic procedure used to obtain peripheral lung tissue. Small size and artefacts cause variable, and usually poor, diagnostic yield. The use of cryoprobes may allow for larger size and better quality biopsy samples. Objectives:To analyze the histological quality and immunohistochemical findings of samples obtained by cryoprobe compared with TBLB obtained by conventional forceps and to assess the safety and complications of TBLB with cryoprobe versus the conventional method. Methodology: Prospective randomized study of 80 patients. The transbronchial lung biopsy was indicated for diagnoses of a interstitial lung disease. In both procedures the videobroncoscopy used will be a Olympus 260-T. The transbronchial lung biopsy will be carried out with conventional forceps (Boston ® Biopsy Forceps, Ref 1556 and Olympus ® FB-19E) and cryoprobe (Erbokryo AC ®). TBLB will be performed by fluoroscopy guided and the cryoprobe or forceps will place in an area of the peripheral lung previously selected according to CT findings. Lung biopsies will be processed: The samples submitted for histological analysis will be fixed in formalin and embedded in paraffin. Staining will perform with hematoxylin-eosin and Masson's trichrome and the samples will be analyzed by a pathologist according to a protocol. The samples submitted to immunohistochemical study will be frozen (liquid nitrogen) for later transport.The specifical monoclonal antibodies will be used for immunohistochemical analysis.
