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.
Phase II Clinical Trial Evaluating the Safety and Efficacy of a Tissue Engineered Autologous Skin Substitute Reconstructive Surgery for Basal Cell Carcinoma
The purpose of this study is to evaluate the safety and tolerability of QEL-001 in the prevention of liver transplant rejection following immunosuppression withdrawal. QEL-001 is a product made from a patients own cells, which are genetically modified and designed to help the transplant recipient's body accept their donated liver and prevent their immune system from rejecting it once immune suppression is withdrawn.
Phase III clinical trial to evaluate the efficacy of the open abdomen as bridging therapy to perform transit reconstruction in patients with anastomotic dehiscence. It is a randomized controlled single-center study that will be carried out at the Virgen del Rocío University Hospital in Seville.
Observational analytic study with a prospective cohort design. Patients with episodic and chronic migraine that have responded to monoclonal antibodies (mAbs) versus calcitonin gene-related peptide (CGRP) or its receptor with positive response will be included. A headache diary will be completed in a daily basis. The primary outcome will be the time elapsed between the discontinuation of the monoclonal antibody and the return to the clinical situation at the moment of the mAbs onset. The potential variables that may be associated with a more sustained benefit will be explored.
This is a prospective, randomized, double-blinded, placebo-controlled, multi-center, Phase 3 study of GLSI-100 immunotherapy in HLA-A*02 positive and HER2/neu positive subjects who are at high risk for disease recurrence and have completed both neoadjuvant and postoperative adjuvant standard of care therapy. Treatment consists of 6 intradermal injections, Primary Immunization Series (PIS), over the first 6 months of treatment and 5 booster intradermal injections spaced 6 months apart. A third open-label arm will explore GLSI-100 immunotherapy in non-HLA-A*02 positive and HER2/neu positive subjects.
This study is a pilot non-controlled clinical trial with adjunctive fenfluramine for the treatment of five different types of developmental and epileptic encephalopathies (DEEs) focused on epileptic and "non-epileptic outcomes": SYNGAP1 and STXBP1 encephalopathies, inv-dup(15) encephalopathy, multifocal or bilateral malformations of cortical development, and continuous spikes and waves during sleep. The main goal is to assess changes in seizure frequency comparing before and after treatment with fenfluramine in five specific types of developmental and epileptic encephalopathies (DEEs). Secondary objectives of this study are the analysis of changes in seizure intensity and duration, and "non-epileptic outcomes" such as variations in cognitive activity, level of alertness, impulsivity/self-control, gait stability and other alterations that might be detected during the interview and physical examination.
Purpose. The aim of this study is to evaluate the impact of the implementation of the Nurse Enhanced Recovery After Surgery Coordinator (NEC), within the Enhanced Recovery After Surgery (ERAS) program, in relation to the compliance of patients undergoing colorectal surgery. Methods. Quasi-experimental study with a control group, an intervention group and without random assignment in a multicenter trial; between December 2021 and November 2023. Patients older than 18 years with planned elective intervention of major colorectal surgery will be included; excluding those without social support, with psychiatric illness, cognitive difficulty, planning of simultaneous or emergency surgery. In the intervention arm they will have NEC and in the control group they will not have that resource. Compliance will be the main variable of the study and, in addition, the study aims to assess secondary endpoints such as quality of life (QOL). Conclusions. NEC could increase compliance to ERAS programs, improving health outcomes and QOL perceived by the patient. The applicability in the different hospital centers could generate an opportunity to advance professionally in the nursing figure within the ERAS program. The fact of having NEC could also increase the efficiency of the program due to the cost-effectiveness of the nursing position, although this is not the object of the study. It would be applicable in improving perceived health and QOL, so it could also have an economic impact on the health system.
Retrospective und prospective registry on HIV-associated lymphoma. Data on characteristics, type and toxicity of treatment and outcome of patients with HIV-lymphoma will be collected.
High-frequency alternating current (HFAC) stimulation (between 1 kilohertz (kHz) and 100 kHz) on the peripheral nerve has been shown in basic animal research to produce a rapidly reversible nerve block without nerve damage. In human studies, frequencies between 1 kHz and 30 kHz had been applied (both transcutaneously and percutaneously), showing rapidly reversible sensorimotor changes after stimulation without adverse effects. However, the effect of currents with a frequency higher than 30 kHz, which has been shown to be more effective in eliciting nerve block in primates, has not been investigated in humans. The main objective of this study is to investigate the safety of the intervention and the effect in healthy volunteers of transcutaneous application of alternating currents with frequencies between 30 kHz and 50 kHz on neurophysiological changes in the nerve (nerve conduction velocity and antidromic sensory action potentials (SNAPs), sensory (pain to pressure, epicritic sensitivity and thermal pain to heat) and motor (maximal isometric force) components of the median nerve.
Objective: To prospectively evaluate clinical outcomes during guideline-recommended LMWH dose escalation for recurrent VTE during LMWH or DOAC treatment for cancer-associated thrombosis. Study design: International, prospective, observational cohort study Study population: Adult cancer patients with symptomatic or incidental recurrent VTE while receiving LMWH or DOACs for acute VTE are eligible. Main exclusion criteria include anticoagulant treatment for the recurrent VTE for more than 72 hours, severe hepatic dysfunction, active bleeding, recent major surgery, uncontrolled hypertension, known bleeding diathesis, and a life expectancy of less than 1 month. Study procedures: Patients will be managed at the discretion of the treating physician, who will be encouraged to follow guideline recommendations. These guidelines suggest supra-therapeutic dose LMWH for 4 weeks (+/- 5 days) followed by therapeutic dose LMWH or therapeutic dose DOAC, while it is suggested to treat patients with VTE recurrence during maintenance dose LMWH (i.e. 75 to 80% of full therapeutic weight adjusted dose) with therapeutic dose of LMWH or DOAC. Main study parameters/endpoints: The co-primary outcomes are new symptomatic or incidental recurrent VTE during 3 months of follow-up and on-treatment major bleeding. Secondary outcomes include recurrent incidental VTE, recurrent symptomatic VTE, recurrent incidental or symptomatic proximal or distal DVT, recurrent incidental or symptomatic PE, clinically relevant non-major bleeding, all-cause mortality, and cancer-related mortality. VTE occurring at other sites such as cerebral DVT or splanchnic DVT will also be recorded.
