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.
Randomized, outcome assessor and data analyst blinded, single center trial with four parallel arms and a 1:1:1:1 allocation ratio, with the aim of comparing which combination of bilaminar technique (split vs. full thickness flap) and graft type (autogenous or xenogeneic) provides better clinical, aesthetic, morphological, vascular and patients related outcomes, when augmenting the buccal peri-implant mucosa at the reopening of submerged implant fixtures
The study is designed to evaluate the safety and efficacy of rusfertide in subjects with polycythemia vera (PV) in maintaining hematocrit control and in improving symptoms of PV.
Phase IV, open-labeled, randomized and multicenter clinical trial to demonstrate the superiority of antibiotics with authorized indication for 7 days versus 14 days in the treatment of bloodstream infections produced by P. aeruginosa (BSI-PA).
Randomized, double-blind clinical trial to compare the efficacy of catheter sealing with saline, compared to low-dose heparin. 3,450 patients hospitalized at the Hospital Residencia Sant Camil, in Catalonia (Spain), will be randomized to each branch of study. The primary outcome will be the percentage of catheters removed due to obstruction in each branch of study. As secondary outcomes, the number of catheter-associated phlebitis, catheter-associated bacetrihemia, extravasation, and catheter loss will be measured. For the primary outcome, a superiority analysis will be carried out in terms of the percentage of obstructed catheters in each branch of the study.
The purpose of this study is to evaluate the effect of moderate or severe liver impairment on the drug levels of oral azacitidine and the safety and tolerability of oral azacitidine in participants with myeloid malignancies.
Phase III study of stereotactic body radiation therapy (SBRT) plus standard of care in castration sensitive oligometastatic prostate cancer patients, defined as androgen deprivation therapy plus radiotherapy to the primary tumor in previously not treated patients and second generation hormonal treatments (Apalutamide/Abiraterone+Prednisone/Enzalutamide) vs androgen deprivation therapy plus radiotherapy to the primary tumor in previously not treated patients plus second generation hormonal treatments, for the treatment of oligometastatic prostate cancer.
This study will test the safety of a drug called SGN-PDL1V alone and with pembrolizumab in participants with solid tumors. It will also study the side effects of this drug. A side effect is anything a drug does to your body besides treating your disease. Participants will have solid tumor cancer that has spread through the body (metastatic) or cannot be removed with surgery (unresectable). This study will have four parts. Parts A and B of the study will find out how much SGN- PDL1V should be given to participants. Part C will use the dose found in Parts A and B to find out how safe SGN-PDL1V is and if it works to treat solid tumor cancers. In Part D, participants will be given SGN-PDL1V with pembrolizumab to find out how safe this combination is and if it works to treat solid tumor cancers.
A vision therapy protocol for vergence ability is mentioned. The purpose of this study is to evaluate objectively the change in the vergence responses of binocular and accommodative normal subjects after performing a classic vision therapy protocol. This study is an interventional, cross-over, and randomized study.
Allergic rhinitis (AR) is a health problem characterised by an inflammatory reaction in the nasal mucosa mediated by immunoglobulin (Ig) E and resulting from exposure to environmental allergens, such as pollen and dust mites. AR symptoms can significantly affect the quality of life of patients suffering from AR, causing substantial direct health care costs and indirect costs due to absenteeism from work. The effects of pharmacological treatments are not always fully effective and have adverse effects, resulting in a significant proportion of AR patients continuing to experience symptoms or being dissatisfied. Considering the relationship between AR and intestinal microbiota (IM), the use of probiotics, live microorganisms that, when consumed in adequate amounts, confer beneficial effects on the host, emerges as a potential strategy to prevent or treat certain allergies. There are different mechanisms of action by which probiotics may exert their effects on the treatment or prevention of allergies through modulation of the immune system and stimulation of tolerance. Probiotics promote a change in IM. In addition, probiotics stimulate gut-associated lymphoid tissue, modulating inflammation and immune reactions present in AR, promoting a more favourable profile by increasing the production of the modulatory cytokines IL-10 and TGFβ by Treg cells. Probiotics can restore the Th1:Th2 balance by inducing Th1 responses through the production of IL-12 and interferon (IFN)-γ, or by suppressing Th2 responses through the depletion of IL-4. In addition, probiotics may exert immunomodulatory effects through stimulating mucosal IgA production. The hypothesis of the present study is that supplementation with the probiotic Bifidobacterium longum ES1 and/or with the heat treated version of ES1 will decrease the symptomatology associated with AR and improve the quality of life of individuals by modulating IM and potentiating Treg cells and the Th1 response. The main objective of the present study is to determine the effects of supplementation with the probiotic Bifidobacterium longum ES1 and the heat treated version of ES1 (HT-ES1) on the symptoms associated with AR. The secondary objectives of the study are to determine the effects of the treatments over: 1) Quality of life; 2) Blood immunological markers (IFN-γ, IL-12, IL-10, TGF-β, IgE, IL-4, IL-13, IL-19 and IL-8); 3) Faecal immunological marker IgA; 4)Faecal microbiota composition.
This is a Phase 3, open-label, international, multicenter study of CGT9486 in combination with sunitinib. This is a multi-part study that will enroll approximately 426 patients. Part 1 consists of two evaluations: 1) confirming the dose of an updated formulation of CGT9486 to be used in subsequent parts in approximately 20 patients who have received at least one prior line of therapy for GIST and 2) evaluating for drug-drug interactions between CGT9486 and sunitinib in approximately 18 patients who have received at least two prior tyrosine kinase inhibitors (TKIs) for GISTs. The second part of the study will enroll approximately 388 patients who are intolerant to, or who failed prior treatment with imatinib only and will compare the efficacy of CGT9486 plus sunitinib to sunitinib alone with patients being randomized in a 1:1 manner.
