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.
Efficacy and safety of ofatumumab and siponimod compared to fingolimod in pediatric patients with multiple sclerosis
Portugal has the highest benzodiazepine utilization compared to other European countries. The high utilization of benzodiazepines has been a concern due to reported side effects of long-term use and dependence. Also, these data demonstrate that doctors are possibly choosing an inadequate treatment to manage anxious and depressive syndromes. This research aims to develop and implement in primary health care units an online educational program, following a cluster randomized study design; to study the impact of this educational program for changing general practitioner's benzodiazepine prescription pattern; to analyze of barriers and facilitators to the implementation of the e-PrimaPrescribe program.
The purpose of this study is to compare the efficacy of Bortezomib, Lenalidomide and Dexamethasone (VRd) induction followed by a single administration of ciltacabtagene autoleucel (cilta-cel) versus VRd induction followed by Lenalidomide and Dexamethasone (Rd) maintenance in newly diagnosed multiple myeloma participants for whom ASCT is not planned as initial therapy in terms of Progression Free Survival (PFS).
This study will assess the efficacy and safety of Niraparib in participants with either tumor mutation in the BRCA gene (tBRCAmut) HER2- breast cancer (Independent of hormone receptor [HR] status, including HR positive [+] and TNBC) or tumor BRCA wild type (tBRCAwt) TNBC with molecular disease based on the presence of circulating tumor Deoxyribonucleic acid (ctDNA) following surgery or completion of adjuvant therapy.
1. Background The purpose of this study is to describe the profile of patients with BRAF-mutated melanoma treated with BRAF/MEK inhibitors combination and using the Tavie Skin application. TavieSkin app, a digital solution developped by Pierre Fabre, is dedicated to all BRAF-mutant unresectable or metastatic melanoma patients who are treated with "any" targeted therapies. 2. Study objectives The primary objective of the survey is to describe the demographics and clinical characteristics of patients with unresectable or metastatic BRAF-mutated melanoma treated with targeted therapy (BRAFi/MEKi) and using the TavieSkin application The secondary objectives include: - To assess the use of TavieSkin app in patients with unresectable or metastatic BRAF-mutated melanoma treated with BRAFi/MEKi combination; - To assess the treatment adherence of patients using TavieSkin app including treatment interruption or permanent discontinuation; - To assess the health-related quality of life of patients using TavieSkin app (FACT-M); - To assess work productivity and activity impairment over the treatment duration - To assess the patient satisfaction toward the TavieSkin application; - To assess the patient satisfaction toward the treatment. 3. Research methods 3.1 Study design This prospective, longitudinal, survey will be conducted in Europe to characterize BRAF-mutant unresectable or metastatic melanoma patients using TavieSkin app designed for accompanying patients treated with targeted therapies. To date, there are three combinations of BRAFi/MEKi available in routine practice for the treatment of BRAF-mutant unresectable or metastatic melanoma. The survey does not provide or recommend any treatment or procedure; all decisions regarding treatment are made at the sole discretion of the treating physicians in accordance with their usual practices. The patients initiating any BRAFi/MEKi combination will be invited to use the TavieSkin app by their healthcare provider (HCP) (i.e. oncologist, dermatologist, nurse…). Once the patient has installed and started to use the application, an e-survey will be proposed to the patient via the app. A detailed information letter about the data collection, data privacy and analysis will be displayed to the patient via the app along with an e-consent for data collection. The patient will be able then to provide an e-signature, if he/she accepts to take part of this survey. The survey will collect anonymized data about health status, QoL data and satisfaction. These data will be collected by the patient only. The physician will not be involved in this e-survey (including e-consent), nor in data collection. Only patients having given consent (e-consent) to data collection and analysis will be included. Data will be collected at baseline and at different subsequent timepoints during the BRAFi/MEKi treatment duration only. Only data reported by the patients in the application will be collected and analyzed. The patient will discontinue the study in case of definitive withdrawal of BRAFi/MEKi treatment, or if he/she decides to withdraw the study and to stop data collection. The target countries for patient enrollment will include Germany, Belgium, Portugal, France, Spain, Italy and Sweden with the additional possibility of including patients from other EU countries. At least, 400 adult patients (≥18 years) will be enrolled. 3.2 Population (see section: Eligibility) 3.3 Study outcomes (see section: Outcome measures) 3.4 Statistical considerations Statistical analyses will be fully described in a written statistical analysis plan (SAP). The study endpoints will be analysed overall and by country. Analyses will be descriptive in nature, as no hypothesis will be tested. The treatment patterns of patients, baseline demographics and clinical characteristics, and reasons for treatment discontinuation will be described using summary statistics. Categorical variables will be summarized by frequencies and percentages. Continuous variables will be summarized by descriptive statistics (mean, and standard deviation, median, 25th and 75th percentiles, minimum and maximum). The number of missing observations for each variable will also be reported. Change in health-related quality-of-life scores (i.e. (FACT-M) will be summarised at baseline and at each timepoints. The change from baseline will be assessed using a mixed model for repeated measures (MMRM). Time to event data (i.e. time to treatment discontinuation, time QoL deterioration) will be evaluated using Kaplan-Meier survival curves. Median survival estimates will be reported along with the 25th and 75th percentiles and corresponding 95% confidence intervals (CIs). Cox regression analysis may be performed to adjust for predefined (baseline) covariates. If the sample size is adequate, subgroup analyses using variables at baseline might be conducted.
This is a randomized, double-blind, placebo-controlled, Phase 2/3 study comparing the efficacy and safety of BLU-263 + best supportive care (BSC) with placebo + BSC in patients with indolent systemic mastocytosis (ISM) whose symptoms are not adequately controlled by BSC. Parts 1 and 2 will enroll patients with ISM. Patients enrolled in Part 1 or Part 2 will roll over onto Part 3 to receive treatment with BLU-263 in an open-label fashion following completion of the earlier Part. Part M will enroll patients with monoclonal mast cell activation syndrome (mMCAS). The study also includes PK groups that will enroll patients with ISM.
This is an international, cross-sectional and descriptive study that aims to investigate differences in patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs) and that aims to explore the profile and healthcare needs of adults with congenital heart diseases.
The purpose of this study was to evaluate the efficacy of GSK3640254 + DTG relative to lamivudine (3TC) + DTG in treatment-naïve adult participants living with human immunodeficiency virus (HIV)-1. The participants were randomized to one of the three doses of blinded GSK3640254 (100, 150, or 200 milligrams [mgs]) or a reference arm of blinded 3TC-each in combination with open label DTG.
