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 purpose of this study is to evaluate whether the addition of selexipag to standard of care treatment delays disease progression in children with Pulmonary Arterial Hypertension (PAH) in comparison to placebo.
Spinal muscular atrophy (SMA) is a neurogenetic disorder caused by a loss or mutation in the survival motor neuron 1 gene (SMN1) on chromosome 5q13, which leads to reduced SMN protein levels and a selective dysfunction of motor neurons. SMA is an autosomal recessive, early childhood disease with an incidence of 1:10,000 live births. SMA is the leading cause of infant mortality due to genetic diseases. Until recently, the mainstay of treatment for these patients was supportive medical care. However, advances in medical treatment focusing on gene replacement, gene enhancement, motor neuron protection and muscle enhancement is likely to change the management and prognosis of these patients in the future. The purpose of this registry is to assess the long term outcomes of patients with SMA in the context of advances in treatment options.
This is a Phase 2/3 study that comprises 5 substudies designed to evaluate the efficacy, safety, and tolerability of oral etrasimod as therapy in adult participants with moderately to severely active Crohn's disease (CD) who are refractory or intolerant to at least 1 of the current therapies for CD (ie, corticosteroids, immunosuppressants, or biologics). The overall duration of this study is up to 282 weeks, inclusive of the Screening Period, Treatment Period of up to 274 weeks (Induction, Extension or Maintenance, and Long-term Extension Periods), and the 4-Week Follow-Up Period for safety assessment.
The primary objectives are to evaluate the safety and tolerability of multiple doses of ION464 administered via intrathecal (IT) injection (Part 1) and to evaluate the long-term safety and tolerability of ION464 (Part 2) in participants with multiple system atrophy (MSA). The secondary objectives are to evaluate the pharmacodynamic (PD) effect of ION464 on the level of a potential biomarker of target engagement (Parts 1 and 2) and to evaluate the pharmacokinetic (PK) profile of ION464 in serum (Part 1).
Tissue acquisition by Endoscopic Ultrasound (EUS) has become a modality of diagnosis and clinical orientation for several diseases. Although tissue acquisition traditionally involves the cytological diagnosis (using fine-needle aspiration/FNA), the importance of obtaining a core for histological examination (by fine-needle biopsy/FNB) has recently been recognized. Currently, there is no clear establishment of the usefulness of syringe suction for the diagnostic accuracy of solid pancreatic lesions when FNB is used. Because of that, the investigators aimed to compare sensitivity, sample adequacy, and diagnostic yield of solid pancreatic lesions EUS-guided sampling using with and without syringe suction. The study will be conducted on a consecutive sample of patients proposed to perform EUS for solid pancreatic lesions characterization, in which the clinical and imaging findings justify the need for an FNB. For each case, FNB will be performed using two punctures: one with 20mL syringe suction, and another without suction. The order in which they will be performed will be known only by the performing physician and the nursing team at the time that FNB is proposed. This information will be concealed from the pathologist responsible for sample analysis. Clinical care during and after the procedure will follow the existing guidelines. Participants will undergo a single clinical evaluation (at the time of endoscopy and recovery) without the need for follow-up visits.
Primary Objectives: - Study is designed with two primary endpoints that will be analyzed on randomized participants at the time of the cut-off date for each given analysis (progression free survival [PFS] and overall survival [OS]) - Study success is defined either on PFS or OS - The primary objective is to determine whether tusamitamab ravtansine improves the progression free survival (PFS) when compared to docetaxel in participants with metastatic non-squamous non-small-cell lung cancer (NSCLC) expressing CEACAM5 greater than or equal to 2+ in intensity in at least 50% of the tumor cell population and previously treated with standard-of-care platinum-based chemotherapy and an immune checkpoint inhibitor (ICI) - The primary objective is to determine whether tusamitamab ravtansine improves the overall survival (OS) when compared with docetaxel in participants with metastatic non-squamous NSCLC expressing CEACAM5 greater than or equal to 2+ in intensity in at least 50% of the tumor cell population and previously treated with standard-of-care platinum-based chemotherapy and an immune checkpoint inhibitor. Secondary Objectives: - To compare the objective response rate (ORR) of tusamitamab ravtansine with docetaxel - To compare the health-related quality of life (HRQOL) of tusamitamab ravtansine with docetaxel - To evaluate the safety of tusamitamab ravtansine compared to docetaxel - To assess the duration of response (DOR) of tusamitamab ravtansine as compared with docetaxel
This study will evaluate the efficacy and safety of vutrisiran 25 mg administered subcutaneously (SC) once every 3 months (q3M) compared to placebo in patients with ATTR amyloidosis with cardiomyopathy.
Study MO39874 is an open-label, Phase IIIb, single arm, global study conducted in participants with unresectable locally advanced or metastatic PD-L1-positive Triple-Negative Breast Cancer (TNBC) who have not received chemotherapy for their unresectable locally advanced or metastatic disease.
The purpose of this study is to determine the proportion of newly diagnosed participants with Human Immunodeficiency Virus (HIV)-1 (naive participants) with virologic response at Week 48-defined as HIV-1 Ribonucleic acid (RNA) less than (<) 50 copies/milliliter (mL) (Food And Drug Administration snapshot) - after the implementation of the Test & Treat model of care and in a historical cohort.
Regularly interrupting sedentary behavior (SB) with activity breaks may attenuate postprandial glucose (PPG) excursions and improve glycemic control. The investigators aimed to determine the effect of interrupting 7 hours of prolonged sitting with brief bouts of moderate physical activity (PA) (alternating between up/down stairs and sit/stand up from the chair) on postprandial glucose (PPG) responses in comparison with uninterrupted sitting. In addition, the investigators aimed to examine the effects of 2 weeks of detraining (DT) on PPG on both protocols. Non-diabetic, trained older adults (n = 15) will be recruited for a randomized crossover trial with two treatments performed in two different training conditions: 1) uninterrupted sitting protocol (CON); 2) seated with 2-minutes bouts of moderate PA every 30 minutes (INT). Both protocols will be performed in a trained condition and after 2 weeks of DT. In the early morning of each trial, participants will do an oral glucose tolerance test (OGTT) and 2 blood samples will be collected (fasting and after 2 hours); 2.5 hours after, participants will begin the protocol and two standardized meals will be provided (0 hours and at 3 hours). An iPro2 continuous glucose monitoring (CGM) system will record the average interstitial glucose concentration every 5 minutes. Positive incremental area under the curve (iAUC) and total area under the curve (pAUC) for glucose as well as mean glucose (MG) will be calculated using Matlab. Differences between both protocols and between the two different moments will be examined using generalized estimation equation (GEE), adjusting for sex and age (CI 95%).
