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.
There is little information of Eastern Cooperative Oncology Group (ECOG) performance status (PS) 2 patients analyzed in the clinical trials. The rate of patients recruited into Treatment Chemotherapy as 1st Line in Advanced NSCLC clinical trials is less than 20 percent. This low rate makes the investigators think about the possibility of a bias selection, due to the existence of this exclusion criteria that do not permit to include patients with deteriorated performance status. In these types of patients, the toxicity is an important issue to decide the therapeutic strategy. Gemcitabine and Docetaxel combination is very interesting because they have a different toxicity profile. This combination has demonstrated activity in several types of tumours, as breast cancer, sarcoma and lung cancer. The strategy performed in this study is biweekly combination of Gemcitabine and Docetaxel; activity and dose intensity will be the same, but toxicity will be significantly low.
It is traditionally considered that the development of Latent Tuberculosis Infection (LTBI) is due to the M. tuberculosis ability to develop a dormancy state within well-structured lesions (granulomas), which can remain in the lung of the host even for life. A new original hypothesis has been developed in the Experimental Tuberculosis Unit based on scientific evidence that take into account the idea that a lesion cannot be held forever, because the host tends to remove any lesion in order to rebuild the original parenchyma, in a healing process. Even if M. tuberculosis can remain in a dormant/non-replicating state for a long period, this is an important but not sufficient factor to explain the LTBI. The Dynamic Hypothesis tries to explain the existence of LTBI in spite of the healing process that could remove it by a constant reinfection of the host's tissue. While the "Static" view defends the induction of active TB after the reactivation of the bacilli from and old lesion; while the "Dynamic" view wants to demonstrate that there is a constant induction of new granulomas. In case one of these new lesions takes place in the upper lobe privileged zone, the possibility to induce a cavity would appear, developing an active Tuberculosis (TB).
It is traditionally considered that someone with a positive tuberculin skin test (TST) (and/or positive result in Cell Interferon-Gamma Release Assay (TIGRA), depending on the different countries' guidelines) is infected but not ill when the absence of lesions is demonstrated in a thorax X-Ray assay. Even though, the experiences described in literature using cows and pigs as animal models for the study of LTBI demonstrate the presence of this kind of lesion in the animals, even too small to be detected by X-Ray assay, which would suggest they also could happen in human LTBI. Nowadays, the High Resolution Scanners (HR TC) offer the possibility of detecting any lesion approximately 1 mm in diameter, so the investigators plan to use this technique to screen people already infected by M. tuberculosis (but not ill, following the Diagnosis Standard Guidelines). Additional pathological analysis of resected and post-mortem tissues will provide lesion-based profiles of humans infected with tuberculosis.
The Increlex® Global Registry is a descriptive, multicenter, observational, prospective, open-ended, non interventional, post-authorisation surveillance registry. The main purpose of this global registry is to collect, analyse and report safety data during and up to at least 5 years after the end of treatment in children and adolescents receiving Increlex® therapy for SPIGFD according to the locally approved product information.
The trial randomise patients with asymptomatic carotid artery narrowing in whom prompt physical intervention is thought to be needed, but there there is still substantial uncertainty shared by patient and doctor about whether surgery or stenting is the more appropriate choice. The study is looking at immediate risks (within one month)and at long term benefits
The purpose of this study is to identify potential biomarkers that may predict the development of Alzheimer's disease in people who carry an Alzheimer's mutation.
The prevalence of patent foramen ovale (PFO) is about 25% in the general population and approximately 40% in patients who have ischemic stroke of unknown cause (cryptogenic stroke). Given the large number of asymptomatic patients, no primary prevention is currently recommended. On the contrary, secondary prevention is very important. Prospective studies have shown that antithrombotic treatment (ATT) with aspirin or warfarin appears to negate the risk of recurrent stroke associated with a PFO. Patients with spontaneous or large right-to-left shunts (RLS), those with a coinciding atrial septal aneurysm (ASA) or multiple ischemic events prior to the PFO diagnosis may still be at increased risk of stroke recurrence despite ATT. Percutaneous device closure (PDC) is a challenging alternative to ATT. Several studies reported 0% to 3.4% annual recurrence rates of stroke or TIA in patients treated by PDC. To date, there is no data from randomized controlled trials (RCT) comparing the risk of stroke recurrence after PDC with that under ATT only. The results from ongoing RCTs are not to be awaited in the near future, mainly due to low enrolment and event rates. Alternative data-gathering strategies such as multicenter registries are needed to overcome the low recruitment rates. The aim of the present study is to compare the risk of recurrent stroke and TIA in patients with PFO and otherwise unexplained stroke who undergo PDC or receive ATT.
INDICATION: Patients with chronic hepatitis C, genotype 1 and non-responders to standard treatment for hepatitis C. OBJECTIVES: 1. ascertain the rate of sustained response in patients with hepatitis C, genotype 1 with peginterferon + ribavirin resistance. 2. To know the response rate in 12 weeks 3. Describe the tolerance and safety of thalidomide in combination with peginterferon and ribavirin. DESIGN OF TEST Pilot Study: The single arm study will: 1. Thalidomide 200 mg and peg-interferon alfa 2b (based on weight: 50-120 mcg / week) + ribavirin (based on weight: 1000-1200mg / day) Be tracked for 24 weeks after treatment. Suspended treatment of 12 weeks in patients who have failed a drop of HCV RNA> 2 log. Patients who have been suspended for any reason, the treatment will be followed during 24 weeks, to assess safety parameters. SUBJECT NUMBER: 10
The purpose of this study is to evaluate the efficacy (and safety) of the following treatment squeme:Ciclophosphamide, Vincristine, lyposomal Doxorrubicine (Myocet) and Prednisone,combined with Rituximab in first line treatment for patients with aggresive No Hodgkin B lymphoma and cardiovascular risk
The purpose of this study is to determine how electrical impedance is modified in relation to extracellular space body fluid retention detected by an electrical bioimpedance method in patients with heart failure.
