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.
Amyotrophic Lateral Sclerosis (ALS) is a progressive and fatal neurological disease. An exhaustive and frequent clinical evaluation can lead to establish an adequate and early treatment of the consequences of its evolution. Objectives. 1. To evaluate the evolution of diaphragmatic and peripheral neuromuscular degeneration by ultrasound examination in patients with ALS and to establish possible evolution patterns. 2. To verify the relationship between the degenerative peripheral and diaphragmatic neuromuscular changes evaluated by ultrasonography and changes in clinical scales frequently used. 3. To compare the ultrasonographic features of subjects with ALS and a sample of healthy subjects Methods. A longitudinal observational study in a consecutive sample of patients diagnosed with ALS will be realized. All the patients will be examined 3 times, with an interval of at least 3 months between tests. Bilateral and cross sectional ultrasonography of several peripheral muscles and diaphragm will be performed at rest and during muscle contraction. All the images will be processed and analyzed for obtaining morphometric variables (muscle thickness) and textural ones (echogenic variation, entropy, homogeneity, textural contrast and correlation). Frequency of twitches will be also recorded in peripheral muscles.Also clinical features will be noted, every time of the 3 exams, from Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-r), British Medical Council Research Scale(MRC), and routine pulmonary tests.
A randomized, double-blind, placebo-controlled, dose-ranging, multi-center study to evaluate the efficacy and safety of GB001 when added to standard-of care (SOC) asthma maintenance therapy in adults with moderate to severe asthma and an eosinophilic phenotype with respect to asthma worsening at the end of 24 weeks of treatment.
The availability of antiretroviral therapy has led to a reduction in morbidity and mortality in patients with chronic HIV infection. The treatment, however, is not free of side effects, has potential interactions with other medications, is expensive and can be complex, especially in those patients who are very experienced and with mutations that give them resistance to multiple drugs. For this reason, the development of simplification strategies that avoid unnecessary exposure to antiretroviral agents remains of great interest. This is a simplification study, in which the investigators try to evaluate that with less medication the investigator can maintain the same virological control of the disease. This would mean a lower burden of medication for patients, facilitating its administration and reducing the number of unwanted side effects. Specifically, the investigators intend to evaluate the treatment with Darunavir / cobicistat plus Dolutegravir as a simplification strategy, since both drugs are taken once a day, have a powerful antiviral activity, even against antiretroviral resistant viruses, and are among the best tolerated (with fewer side effects). The results reported in some observational studies suggest that two-drug therapy (bitherapy) as a simplification strategy could also be safe and effective, however, as far as the investigators know, there are no data and clinical trials that specifically evaluate darunavir / cobicistat plus dolutegravir as a strategy of simplification.
A Phase I Trial of Donor Regulatory T-cells for Steroid-Refractory Chronic Graft-versus-Host-Disease in patients who do not obtain complete remission with ruxolitinib
AIMS-2-CT-01 is a randomized, double-blind, placebo controlled, study to explore the efficacy, safety and tolerability of Arbaclofen administered to children and adolescents (ages 5-17) for the treatment of social adaptive function in participants with ASD. The effects of Arbaclofen on social function in children and adolescents with ASD will be evaluated in a randomized, placebo controlled, parallel-group study of 16 weeks duration. Subjects who meet protocol criteria will be randomly allocated to receive either Arbaclofen or placebo in a 1:1 ratio in the Treatment Period. There will be 7 recruiting sites and randomization will be stratified by site. A sample of 130 patients will be recruited. Blinding will be maintained by utilizing identical tablets containing either Arbaclofen or placebo.
This was a phase 2 study to evaluate the safety and efficacy of elsubrutinib (ELS) and ABBV-599 (ELS plus upadacitinib [UPA]) vs placebo on a background of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) for the treatment of signs and symptoms of rheumatoid arthritis (RA) at 12 weeks in biological disease-modifying anti-rheumatic drugs (bDMARD)-inadequate response (bDMARD-IR) or bDMARD-intolerant participants with moderately to severely active RA and to define optimal dose for further development.
The study aims to evaluate the clinical and radiological behavior, the histological and morphometrical components, the expression of proteins related to bone formation, and the analysis of markers of reparative mesenchymal stromal cells, after using a biphasic phicogenic biomaterial in comparison with anorganic bovine bone. A randomized split-mouth clinical study is designed to include patients in need of two-stage bilateral maxillary sinus floor elevation. Patients are assigned to receive a mix of autogenous bone and a biphasic phycogenic biomaterial in one maxillary sinus and a mix of autogenous bone and xenograft bovine hydroxyapatite in the other maxillary sinus. Cone-beam computerized tomography (CBCT) scans are performed before sinus floor elevation and 6 months after the procedure to assess the bone gain. Bone core biopsies are obtained at the site of implant placement 6 months after the floor elevation. Histological sections are subjected to histomorphometric and immunohistochemical evaluation of differentiation markers.
The clinical trial is designed as a phase II, crossover clinical trial. It will be carried out in healthy volunteers, who will receive two different antibiotic regimen based on ceftriaxone. One of the regimens had shown clinical effectiveness in this scenario, but it is not suitable for OPAT programs. In the other hand, a new treatment schema useful in OPAT programs is proposed, but there is still a lack of pharmacokinetic data to support it. The plasma drug concentrations will be measured in both cases, comparing the minimal drug concentration observed and the pharmacokinetic profiles of the two regimens.
Study to assess the long term safety and tolerability of daridorexant in adult and elderly subjects suffering from difficulties to sleep
The purpose of this study is to assess the clinical activity and safety of INCMGA00012 in participants with advanced solid tumors where the efficacy of PD-1 inhibitors has previously been established.
