All clinical trials

A prospective single-centre pilot study investigating the feasibility and safety of EUS-guided choledochostomy as primary drainage strategy in patients with distal malignant biliary obstruction using a FCSEMS through LAMS to reduce stent dysfunction.

The aim of this phase II, randomized, double-blind clinical trial is to evaluate the effect of home-based transcranial direct current stimulation (tDCS) in patients with treatment-resistant depression. Major depressive disorder is defined by depressed mood and/or loss of interest in activities, during most of the day, nearly every day, for at least two weeks. It is usually accompanied by other symptoms, such as fatigue, sleep disturbances, thoughts of guilt, suicidal ideation, appetite alterations, difficulty to focus and physical agitation or retardation. It is estimated that its worldwide prevalence is 5%, affecting 280-300 million people. A third of patients with depression will develop treatment resistant depression, where symptoms fail to remit after at least two trials of antidepressants. Beyond psychotropics, another treatment option is neuromodulation, where excitatory or inhibitory signals are delivered to the brain, in order to modulate cortical excitability. The tDCS is a non-invasive brain stimulation method that applies a low intensity direct current (1-2mA) directed to the scalp via the cathode and anode electrodes. The current reaches the cortex, facilitating hyperpolarization or depolarization of the axonal membrane potential. Evidence has shown that this method is presented as a technique able to alter cortical and subcortical neural networks. This technique has been used to treat psychiatric disorders such as depression, bipolar affective disorder, panic, hallucinations, obsessive compulsive disorder, schizophrenia, withdrawal, rehabilitation after stroke and pain syndromes such as neuropathic pain, migraine and fibromyalgia. It has a low cost and less side effects than psychotropic medications. In order to be effective, daily repeated sessions of 20-40 minutes are necessary. When applied in a hospital setting, this frequency of sessions can limit its appliance, especially for depressed patients, whose symptoms include fatigue and loss of interest in activities. Furthermore, transportation costs, frequent absences from work and other activities and overload of the healthcare system would also limit its use. Home based devices are portable and easily operated. Thus, it is possible for patients to administer themselves the treatment, in their own home, everyday. Therefore, the aim of this study is to evaluate the effect of home-based tDCS in treatment resistant depression patients in long-term treatment.

The aim of this study is to analyze the effectiveness of three different montages of transcranial direct current stimulation (tDCS) in treating treatment-resistant OCD.

This study will evaluate the efficacy and safety of astegolimab compared with placebo in participants with chronic obstructive pulmonary disease (COPD) who are former or current smokers and have a history of frequent exacerbations.

The goal of the study is to prospectively evaluate and compare Hydrus microstent to the iStent Inject Wide in combination with cataract surgery in patients with mild to moderate open angle glaucoma. Hydrus and iStent are the two FDA approved trabecular meshwork targeting microstents to treat open angle glaucoma in conjunction with cataract surgery.

The trial´s main goal is to explore the use of transcranial direct current stimulation (tDCS) as a treatment option for persons suffering from orofacial pain. The aim of the trial is to further investigate the efficacy and longevity of tDCS in treating chronic pharmacoresistant orofacial pain. A prospective, randomized, double-blinded, two-arm, sham-controlled design will be utilized. Primarily, the analgesic effect's intensity and duration will be assessed. Secondarily, the associated reduction of symptoms of anxiety and depression will be investigated, as well as the impact on the general quality of life. Anodal stimulation (6 sessions in 2 weeks, 2mA, 20 min, cathode over the opposite Fp area) of M1 contralateral to the pain location will be employed. Washout periods of 48-72 hours will be kept between applications to improve neuroplasticity changes' induction, which is estimated to reflect in the effect retention. Eight major evaluation points will be employed in 26 weeks, and a daily numeric rating scale (NRS) self-assessment. The trial will potentially improve the quality of life, reduce the health burden caused by chronic orofacial pain, and provide further data on the use of tDCS in this setting, thus, enabling an additional route to manage the symptoms of pain in the future.

IT001-310 is a clinical study which compares the effectiveness of oral sulopenem versus oral amoxicillin/clavulanate for the treatment of adult women with uncomplicated urinary tract infection.

This open-label clinical trial will enroll patients with aMCI or mild AD, and they will be treated with DAOIB for 24 weeks. We will assess the patients before entering the study, 8 weeks, 16 weeks, and end point (24 weeks) of the study, and measure blood NMDA and oxidative stress - related biomarkers every 8 weeks. We hypothesize that NMDA and oxidative stress - related biomarkers can predict the efficacy of DAOIB for patients with aMCI or mild AD.

The aim of this research is to evaluate the impacts of an intervention that reminds people of the affective rewards of exercise on physical activity in adults of any activity level

This study will evaluate the efficacy and safety of ceralasertib followed by durvalumab plus nab-paclitaxel in 37 patients with TNBC, whose tumor relapsed following treatment with curative intent for early disease, which must have included immunotherapy and chemotherapy as part of the radical locoregional therapy (either adjuvant, neoadjuvant or both).
