There are about 3194 clinical studies being (or have been) conducted in Portugal. 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.
Surgical removal of third molars is recognized as one of the most frequent procedures performed in oral surgery. Literature is rich in studies attempting to demonstrate the benefit of corticosteroids in third molar surgery, however the variety of methods, doses, routes and timing of administration has hampered the standardization of their use in light of best evidence. Also the use of 3D facial superimposition methodology to measure and analyze facial swelling after third molar surgery is a relatively new and promising technology.
The primary objective of the study is to determine the effect of seralutinib on improving exercise capacity in subjects with WHO Group 1 PAH who are FC II or III. The secondary objective for this trial is to determine time to clinical worsening.
The purpose of this study is to learn if V940 which is an individualized neoantigen therapy (INT; formerly, called messenger ribonucleic acid [mRNA]-4157) with pembrolizumab (MK-3475) is safe and prevents cancer from returning in people with high-risk melanoma. Researchers want to know if V940 with pembrolizumab is better than receiving pembrolizumab alone at preventing the cancer from returning.
This study aims to assess the efficacy of two cognitive training programs - one tablet-based (NeuroAIreh@b) and one in paper-and-pencil format (Task Generator) - in improving cognitive and noncognitive outcomes among community-dwelling stroke survivors. This study will include a waiting-list control group to assess the impact of these interventions and provide further insights into their potential for stroke survivors.
The purpose of this study is to assess efficacy and safety of neoadjuvant durvalumab in combination with platinum-based chemotherapy (CT) given as initial therapy after cancer diagnosis followed by either surgery and adjuvant durvalumab or chemoradiotherapy (CRT) and consolidation durvalumab given alone as further therapy in participants with resectable and borderline resectable stage IIB-IIIB NSCLC.
The primary objective of this study is to compare progression-free survival (PFS) in participants who receive sotorasib with platinum doublet chemotherapy versus participants who receive pembrolizumab with platinum doublet chemotherapy.
This is a phase 2 study to evaluate the safety, efficacy and tolerability of ARGX-117 in Deceased Donor Kidney Transplant Recipients at Risk for Delayed Graft Function
Transdiagnostic approaches have been proposed as more truthfully representing mental health problems. Acceptance and Commitment Therapy (ACT) is a transdiagnostic approach that proposes Psychological Inflexibility/Flexibility (PI/PF) as the root of human suffering/flourishing. ACT has been recognized as conceptually and clinically relevant for adult disorders. However, during adolescence, when anxiety disorders are highly prevalent, the same evidence is scarce. Specifically, methodologically robust designs investigating ACT's efficacy on adolescents' ADs are scarce and mechanisms underlying change during ACT for adolescents with ADs have not been investigated. Therefore, this study aims to adapt, implement, and investigate the efficacy of an online delivered (through videoconference) ACT intervention to adolescents presenting SAD or GAD, thus contributing to amplifying the transdiagnostic application of ACT to these disorders. A Randomized Controlled Trial (RCT) with 3 groups (i.e., Control, GAD intervention, and SAD intervention groups) of adolescents aged between 14 and 18 years old will be conducted. Outcome measurement will be assessed at pre-intervention, post-intervention, and at 3- and 6-month follow-ups. The investigators expect improvements in outcome variables (e.g., anxiety symptoms) at post-treatment for intervention groups. When comparing changes in outcome variables between the control and the intervention groups, improvements are expected only in the groups receiving intervention. Additionally, similar effects on outcome measures are expected in both intervention groups with gains being maintained over time (i.e., at 3- and 6-months follow-up). Finally, changes in PI/PF processes are expected to predict changes in outcome variables in both intervention groups. This RCT will provide valuable insights that can potentially enhance the efficacy of treatment modalities, contributing to improved well-being for adolescents with ADs.
In the current study, the investigators will characterize obsessive-compulsive disorder (OCD) patients and healthy controls with a comprehensive clinical and neuroimaging assessment, focusing on the basic psychological processes related and on the neurobiological underpinnings of emotion regulation (ER). After a baseline assessment, the investigators will implement an internet-based cognitive behavioral therapy (iCBT) protocol and assess its efficacy on the modulation of ER and OCD severity. Specifically, the investigators will (1) examine to what extent the iCBT intervention modulates ER and the associated neurobiological mechanisms and (2) identify candidate biomarkers of successful treatment response.
The main goal of this trial is to learn whether eptinezumab helps reduce the number of days with episodic migraine in pediatric participants.
