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 assess the long-term safety of vedolizumab versus other biologic agents in participants with Ulcerative Colitis (UC) or Crohn's Disease (CD).
Quizartinib is an experimental drug. It is not approved for regular use. It can only be used in medical research. Adults might be able to join this study after bone marrow tests show they have a certain kind of blood cancer (FLT3-ITD AML). Participants will have an equal chance of receiving quizartinib or placebo along with their chemotherapy.
To explore two modalities of treatment initiation (Pre-discharge, and Post-discharge) with LCZ696 in HFrEF patients following stabilization after an ADHF episode.
This is a randomized, Phase III, multicenter, open-label study designed to evaluate the safety and efficacy of atezolizumab in combination with cisplatin or carboplatin + pemetrexed compared with treatment with cisplatin or carboplatin + pemetrexed in participants who are chemotherapy-naive and have Stage IV non-squamous NSCLC. Eligible participants will be randomized by a 1:1 ratio into 2 groups: Arm A (Atezolizumab + Carboplatin or Cisplatin + Pemetrexed) and Arm B (Carboplatin or Cisplatin + Pemetrexed). The study will be conducted in two phases: Induction Phase and Maintenance Phase.
This study evaluates the effect of iron chelation as a therapeutic strategy to slow the progression of Parkinson's disease. Half of participants will receive the deferiprone to 15 mg / kg twice daily morning and evening (30mg / kg per day), while the other half will receive a placebo. The treatment lasts nine months.
NOTE: The study data was transferred to zr pharma& following the divestment of Panobinostat to pharma&. Prior to study completion under the sponsorship of Secura Bio, the study was initiated and conducted in part under the sponsorship of Novartis. The purpose of this study is to investigate the safety and efficacy of three different regimens of PAN (20 mg TIW, 20 mg BIW, and 10 mg TIW) in combination with s.c. BTZ and Dex and to provide exposure, safety and efficacy data to identify the optimal regimen of PAN in a randomized, 3-arm parallel design. This study will also assess the impact of administering s.c. BTZ (in combination with PAN and Dex) twice weekly for 4 cycles, and then weekly starting from Cycle 5 until disease progression in patients ≤ 75 years of age. Patients > 75 years of age will receive for the entire treatment period s.c. BTZ weekly (in combination with PAN and Dex) until disease progression. Patients will be treated until disease progression or until they discontinue earlier due to unacceptable toxicity or for other reasons. Patients who discontinued study treatment for reasons other than disease progression will be followed for efficacy every 6 weeks. All patients will be followed for survival until the last patient entering long-term follow-up has completed a 3-year survival follow-up or discontinued earlier.
This trial is conducted in Asia, Europe and the United States of America (USA). The aim of the trial is to investigate efficacy and safety of semaglutide versus dulaglutide as add-on to metformin in subjects with type 2 diabetes.
The main purpose of this study is to compare the Human Acellular Vessel (HAV) with ePTFE grafts when used for hemodialysis access.
The primary aim of this study is to evaluate if VTIQ in addition to BI-RADS® categorization can improve the diagnostic accuracy with respect to detection of malignancies, in particular for BI-RADS® categories 3 and 4a. The idea of the study is to restage all patients in categories 3 and 4a according to a predefined VTIQ cut-off value of ≥ 3.5 m/s (37 kPa).
Type 2 diabetes is a chronic disease that affects approximately 13% of Portuguese population and is associated with a high cardiovascular mortality by coronary artery disease and cerebrovascular disease and with a serious decline on well-being. Lifestyle changes are widely recommended to the control of type 2 diabetes and its complications. This study aims to analyse the effects of different community-based lifestyle programs (exercise or exercise plus dietary intervention) on health and well-being in patients with type 2 diabetes.
