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 rate of sustained virological response (SVR) in patients with chronic hepatitis C, genotype 3, high viral load and without rapid virological response (RNA-HCV negative at week 4) is low. Standard of care of these patients include treatment with weekly peginterferon plus 800 mg/day of ribavirin (RBV). Extended treatment to 48 weeks does not provide more clinical benefit than the standard duration. The main hypothesis is that higher dose of ribavirin may be better in terms of SVR than the standard dose.
Exploratory study assessing the effect of three gonadotrophin protocols on Controlled Ovarian Stimulation (COS) parameters and IVF outcome in oocyte donors undergoing GnRH analogue (long protocol). 1,028 donors were randomized in three groups: Group I (n= 346) only r-FSH, Group II (n= 333) only HP-hMG and Group III (n= 349) r-FSH plus HP-hMG. IVF outcome of 1,059 oocyte recipients was compared.
Patients with moderate to severe renal impairment scheduled for a magnetic resonance imaging (MRI) scan and injection with a contrast agent, Gadovist, will be asked to participate. The administration of contrast agents that contain gadolinium such as Gadovist might increase a potential risk to develop a rare condition called nephrogenic systemic fibrosis (NSF) in patients with renal impairment. This study is to assess the potential risk to develop NSF in patients with renal impairment after the administration of Gadovist. Patients who are enrolled in this study will receive a Gadovist enhanced MRI scan which was prescribed by the referring doctor. After the MRI scan the patient will be included in a two year follow-up period to assess if signs or symptoms suggestive of NSF have appeared.
Ionizing radiation has cytotoxic effects, and is commonly used as treatment for neoplasm. A common adverse effect of radiation is acute diarrhoea. Glutamine is an aminoacid with antioxidant effects that can protect tissues of damage dued to radiation. The investigators designed a randomized, double-blind trial phase III to study if glutamine prevents acute radiation enteritis.
This study is a prospective, randomized controlled, single blind, two-arm, multi center clinical evaluation. A total of 1500 patients will be enrolled in the study. Patient randomization will be to one of the two treatment arms: Everolimus arm or Non drug eluting stent arm. The objective of this study is to assess the safety and performance of the Everolimus Eluting Coronary Stent System versus a modified cobalt chromium balloon expandable stent in the setting of primary percutaneous coronary intervention for treatment of patients presenting with ST-segment elevation myocardial infarction.
The purpose of this study is to characterize three year descriptive growth and development (ie, height, weight, body mass index, Tanner Stage) and efficacy of cholesterol reduction in pediatric subjects with Heterozygous Familial Hypercholesterolemia receiving atorvastatin treatment.
This is a pilot study to examine if the novel treatment regimen maraviroc plus boosted atazanavir can be expected to be safe and efficacious in treatment naive HIV infected patients. Based on the results from this study, a confirmatory phase 3 study may be conducted.
The primary objective of the study is to assess the safety and effectiveness of SPG stimulation with the ISS in patients with an acute ischemic stroke in the anterior circulation initiated within 24 hours from stroke onset.
The purpose of this study is to determine if Brivanib is an effective treatment for liver cancer in patients who have failed or could not take Sorafenib
This study is conducted in Europe, North America and Asia. The aim of this observational study is to evaluate the safety and effectiveness while using Levemir® once daily in combination with oral antidiabetic drugs in type 2 diabetics during 24 weeks under normal clinical practice. Data from the NN304-3573 study (NCT00740519) will be pooled with data from this study and reported together in the final study report for this study.
