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 present project is an ambispective study designed to answer how HLA-F SNPs, as well as KIR-HLA-C compatibility, influence reproductive outcomes in oocyte donation cycles. On the one hand, healthy patients without history of RIF and RM and with indication of egg donation cycle as ART treatment will be genotype for KIR, HLA-C and HLA-F. HLA-C from male partners and egg donors will be also analyzed. No matching based on HLA-C genotypes would be performed and donors would be assigned to recipients following the routine clinical practices. After SET, patients will be followed up until delivery or until the end of treatment. On the other hand, access to data from patients who have equally undergone oocyte-donation cycles, who meet the inclusion criteria and who have been genotyped for KIR and HLA-C as a matter of routine practice, will be requested. For this study, only the first SET of oocyte-donation that patients undergo will be considered. LBR will be the primary endpoint of the study. In addition, secondary endpoints such as embryo development, sustained implantation, progesterone levels, implantation failure, miscarriage rate and unwanted events (preeclampsia, fetal grow restriction, premature birth, low birth weight…) will also be evaluated.
The goal of this observational study is to longitudinally investigating subjects with inaugural acute optic neuritis (ON). The main questions it aims to answer are: - Does the time to corticosteroid treatment affect the visual outcome at 6 months in subjects with acute multiple sclerosis (MS)-, aquaporin 4-IgG positive (AQP4-IgG+) and myelin-oligodendrocyte-glycoprotein-IgG positive (MOG-IgG+) ON? - How differ clinical, structural, and laboratory biomarkers in subjects with acute ON, including clinical isolated syndrome (CIS), MS-ON, AQP4-IgG+ON, MOG-IgG+ON and seronegative non-MS-ON? Participants will undergo - clinical examination, including clinical history, neurovisual and neurological tests - serum and cerebrospinal fluid examination - optical coherence tomography (OCT) - magnetic resonance imaging (MRI) - assessment of depression, pain, quality of life through validated questionnaires Researchers will compare subjects with MS-ON, AQP4-IgG+ON, MOG-IgG+ON and other ON (CIS, seronegative non-MS-ON) to detect diagnostic and predictive markers for the disease course.
The goal of this clinical study is to compare the study drug, axicabtagene ciloleucel, versus standard of care (SOC) in first-line therapy in participants with high-risk large B-cell lymphoma.
The primary objective of this study is to obtain prospective baseline documentation of annualized bleeding rates (ABRs) and treatment under standard-of-care (SOC) therapy among participants with hemophilia A or B. Participants in the study may be eligible to enroll in future planned interventional studies to be conducted by Sponsor.
Neck pain frequently present comorbidities in peridiaphragmatic organs. The innervation of these organs include the phrenic nerve. It is known that peridiaphragmatic organs trigger referred pain in the neck area. As well, previous studies have shown that visceral disorders increase sensitization in somatic tissues. This study aims to analyze the ability of phrenic nerve infiltration to diminish sensitization and improve neck symptoms in the absence of neurological, traumatic or infectious pathology that justifies the pain, by means of a randomized controlled trial.
Alternatives to institutionalization with adapted housing and community supports may allow institutionalized people who so desire to be deinstitutionalized and continue their life in the community. This transition can fulfill the wishes of these people and may improve the quality of their life and functionality.
Treatments are needed to improve outcomes among patients hospitalized for COVID-19, including direct-acting antiviral (DAA) agents to mitigate the pathology driven by ongoing viral replication. This trial will evaluate S-217622 (ensitrelvir), an anti-SARS-CoV2 3C-like protease inhibitor (PI) developed by Shionogi &; Co. Ltd. The study design is a randomized, placebo-controlled, multi-center international clinical trial that will evaluate the clinical efficacy of ensitrelvir when given in addition to standard of care (SOC) for inpatients with COVID-19. The SOC will be determined by local established guidelines and may include additional DAA (e.g., remdesivir) and immunomodulatory treatment strategies. Certain SOC treatments will be pre-specified prior to randomization.
Differentiation between major depressive disorder (MDD) and bipolar disorder (BD) as soon as possible in the patient journey represents a major clinical issue. When the patient is in a depressive phase, the symptoms are similar between the two pathologies and the current clinical scales fail in distinguishing them. Physicians often report this difficulty and as a consequence, the mean time from onset to bipolar disorder diagnosis is currently 7.5 years. These diagnostic delays and misdiagnosis lead to damaging consequences for patients and their loved ones: worsening of symptoms, comorbidities, suicide risk and inadequate care resulting in severe impairment in social and occupational functioning. Faced with these high expectations for accurate diagnostic methods for an earlier management of psychiatric patients, the combination of relevant clinical features and biomarkers could stand for a solution, leading to a personalised approach in patients with mood disorders. In a first clinical discovery study, a panel of RNA biomarkers in the blood of patients with a major depressive episode (MDE) has been identified, allowing to differentiate bipolar disorder from MDD (unipolar depression). These biomarkers are based on RNA modifications, namely RNA editing, that could be identified using molecular biology, NGS and artificial intelligence. This panel constitutes EDIT-B test, which is based on Alcediag's proprietary and patented biomarkers and algorithms. The present study aims to validate the biomarker signatures proposed by Alcediag by measuring the association between the modifications of the RNA editing and major depressive disorder/ bipolar disorder diagnosis, in patients with a MDE in real-life setting pilot centres.
Prospective multicenter observational study evaluating the performance of pressure wave-guided atrial fibrillation cryoablation used in accordance with clinical practice guidelines.
The purpose of the study is to determine the efficacy and safety of the effects of a topical medication on bone remodeling after dental extraction, in order to establish whether such treatment can be a new therapeutic option for said pathology. The participation of 60 patients is expected, who will be divided randomly in equal proportions into two groups. Treatment groups: Group A (30 patients): medication administered topically. Group B (30 patients): placebo with characteristics equal to the drug under investigation.
