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.
The objective of this study was to collect data both retrospectively and prospectively in order to evaluate the long-term outcomes, durability of effect, and real-world treatment patterns following treatment with Cladribine Tablets or placebo in participants with multiple sclerosis (MS) who were previously participated in the parent studies (ORACLE MS and CLARITY/CLARITY-EXT).
This study will evaluate the safety, tolerability, and descriptive efficacy of BIIB017 in pediatric participants with relapsing-remitting multiple sclerosis (RRMS) and to assess the pharmacokinetics (PK) of BIIB017 in pediatric participants with RRMS in Part 1. In Part 2, the study will evaluate the long-term safety of BIIB017 and further describe safety and the long-term multiple sclerosis (MS) outcomes after BIIB017 treatment in participants who completed the study treatment at Week 96 in Part 1 of the study.
The study uses a case-control design that examines the differences in types of exposures between cases defined with a pathological confirmation of GC diagnosis, and controls, defined as patients to whom a gastroscopy was indicated and confirmed absent of GC i
The aim of this study is to teach participants with a OCD diagnosis and treatment-resistance how to decrease the response from a brain region involved in the disease by using a technique called neurofeedback. While using this technique, the participants visualize their own brain response in a screen during a MRI exam. Participants will learn strategies to decrease brain responses. The neurofeedback technique is non-invasive, without known risks to participants. With this study, it is expect that the neurofeedback training over 2 weeks (2 sessions) will reduce the OCD symptoms when compared to a control intervention based on neurofeedback's placebo effects.
This study will evaluate the efficacy and safety of OZURDEX in patients with Diabetic Macular Edema when used in a real world setting in Spain and Portugal.
The purpose of this open-label extension (OLE) study is to evaluate the safety and efficacy of etrasimod in participants with moderately to severely active ulcerative colitis (UC) who previously received double-blind treatment (either etrasimod 2 mg per day or placebo) during participation in one of the qualified Phase 3 or Phase 2 double-blind, placebo-controlled parent studies including but not limited to: (APD334-301 [NCT03945188] or APD334-302 [NCT03996369] or APD334-210 [NCT04607837]).
To assess whether edoxaban (60/30 mg daily) compared to non-antithrombotic medical therapy (either no antithrombotic therapy or antiplatelet monotherapy) reduces the risk of stroke (composite of ischemic, hemorrhagic and unspecified stroke) in high-risk atrial fibrillation (CHA2DS2-VASc ≥2) patients with previous intracranial hemorrhage.
The purpose of the protocol is to estimate the progression-free survival (PFS) rate in subjects diagnosed with PanNET, according to investigator assessment, at 24 months after treatment initiation with lanreotide 120 mg every 28 days.
Two modes of laser (Er:YAG) treatment for snoring will be compared with sham treatment in a randomized clinical trial.
This investigation will focus on the use of EDDY tips, because it is known that the complete debridement of the canal is very difficult, which leads to an accumulation of tissue debris, bacteria and their products, resulting in persistent periradicular inflammation. So, it's of great importance, the study of other approaches of cleaning and disinfecting the root canal, which at the same time, may produce a lower risk of postoperative pain. The above mentioned topics have never been analysed simultaneously with the use of EDDY tips, and the evaluation of the postoperative pain was never addressed. This research is of great clinical interest, due to the complexity of root canal system, with isthmuses, ramifications and dentinal tubules, that make the total elimination of bacteria impossible, even with the best clinical protocols, because the irrigants cannot penetrate the dentinal tubules, and the postoperative pain is an exhausting factor for patients. Therefore, a new protocol, with better disinfection rate and less postoperative pain, will be able to increase the success rate of endodontic treatments, allowing to save condemned teeth.
