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 study will investigate the efficacy, safety, tolerability and Pharmacokinetic(PK) of 3 doses of empagliflozin compared with placebo over 26 weeks in 960 patients with type 1 diabetes mellitus as adjunctive therapy to insulin
This Registry is an investigator-initiated, international, multicenter, observational, prospective study aiming at: i) evaluating non-invasive 24-h ambulatory blood pressure and arterial stiffness estimates (through 24-h pulse wave analysis) in hypertensive subjects; ii) assessing the changes in estimates following treatment; iii) weighing the impact of 24-h pulse wave analysis on target organ damage and cardiovascular prognosis; iv) assessing the relationship between arterial stiffness, blood pressure absolute level and variability, and prognosis. Approximately 2000 subjects, referred to 20 hypertension clinics for routine diagnostic evaluation and follow-up of hypertension, will be recruited. Data collection will include ambulatory blood pressure monitoring, performed with a device allowing simultaneous non-invasive assessment of blood pressure and arterial stiffness, and clinical data (including cardiovascular outcomes). A web-based telemedicine platform will be used for data collection. Subjects will visit the centers at 6-12 month intervals. First follow-up results are expected to be available in the next 2-years. The results of the Registry will help defining the normalcy thresholds for current and future indices derived from 24-h pulse wave velocity, according to outcome data. They will also provide supporting evidence for the inclusion of such evaluation in recommendations on hypertension management.
The purpose of the trial is to determine the safety and efficacy of RPC1063 in patients with relapsing multiple sclerosis.
The purpose of this study was to demonstrate superiority with regard to Overall Survival (OS) or Progression Free Survival (PFS) of avelumab versus platinum-based doublet, based on an Independent Review Committee assessment, in Non-small cell lung cancer (NSCLC) participants with Programmed death ligand 1+ (PD-L1+) tumors.
This research study is done to test how well different types of cancer respond to the drug called larotrectinib. The cancer must have a change in a particular gene (NTRK1, NTRK2 or NTRK3). Larotrectinib is a drug that blocks the actions of these NTRK genes in cancer cells and can therefore be used to treat cancer.
The vascular fingerprint is a simple selection tool to identify testicular cancer patients with a high risk of arterial cardiovascular events during and in the first year after cisplatin chemotherapy. Eventually, this selection method allows a relative small randomized intervention study with i.e. LMWH during chemotherapy to prove the effectiveness and safety in lowering the chance of an arterial cardiovascular event.
This study seeks to determine whether the addition of ABT-414 to concomitant radiotherapy and temozolomide (TMZ) followed by combination of ABT-414 with adjuvant TMZ prolongs overall survival (OS) among participants with newly diagnosed glioblastoma (GBM) with epidermal growth factor receptor (EGFR) amplification. In addition, there is a Phase 1, open-label, multicenter sub-study to assess the pharmacokinetics, safety and tolerability of ABT-414 in participants with newly diagnosed EGFR-amplified GBM who have mild or moderate hepatic impairment.
The purpose of the trial was to evaluate the efficacy and safety of two different doses of QVM149 (QVM149 150/50/80 μg and QVM149 150/50/160 μg via Concept1) over two respective QMF149 doses (QMF149 150/160 μg and QMF149 150/320) μg via Concept1 in poorly controlled asthmatics as determined by pulmonary function testing and effects on asthma control.
The present study evaluates clinical outcomes and treatment-related toxicity following definitive ultra-high dose external beam radiotherapy delivered with two different regimens in patients with intermediate-risk adenocarcinoma of the prostate. Modern computer-driven technology enables the implementation of ultra-high hypofractionated Image-Guided Radiotherapy (IGRT) safely. Prostate cancer patients classified according to the current National Comprehensive Cancer Network (NCCN) guidelines as intermediate risk (biopsy Gleason score of 7 and/or Prostate Specific Antigen (PSA) level >10 and ≤20 ng/mL and/or Stage T1, T2a, T2b or T2c) are eligible for this study. Patients will undergo IGRT with volumetric intensity-modulated arc radiotherapy (VMAT) with state-of-the-art treatment-planning and quality assurance procedures. Emphasis is placed on normal tissue sparing and delivery accuracy via the use of devices that ensure stability and beam location reproducibility. A rectal balloon with air filling will be used for prostate target immobilization and anatomical reproducibility, while a urethral catheter loaded with beacon transponders will be used to ensure set-up reproducibility and online target tracking. Previously untreated patients with intermediate-risk prostate cancer will be prospectively randomized to receive either 45 Gy in five fractions of 9 Gy each vs. 24 Gy in a single-dose. Patients will be followed at one month post-treatment and every 3 months for up to 12 months (+/- 4 weeks) and every 6 months thereafter. Acute and chronic toxicity evaluations will focus on urinary, rectal and sexual functions and will be assessed through validated questionnaires. Serum PSA values will be regularly acquired during follow-up. A multiparametric MRI will be performed at baseline, 6, 12 and 24 months following intervention. Additionally, a post-treatment diffusion-weighted MRI (DW-MRI) will be performed within 15 minutes of the first treatment, to measure early physiologic changes, such as perfusion and ischemia, that may correlate with clinically relevant end-points. Post-treatment prostate needle biopsies will be obtained at 24 months to evaluate pathologic response to therapy. The study will be continuously monitored for a minimum of 5 years. In the event unexpected severe (grade ≥3) toxicities are observed in any one of the treatment arms, the study will be terminated according to the stopping rule >3/first 15 patients.
Phase III randomized clinical trial of lurbinectedin (PM01183)/doxorubicin (DOX) versus cyclophosphamide (CTX), doxorubicin (DOX) and vincristine (VCR) (CAV) or topotecan as treatment in patients with small-cell lung cancer (SCLC) who failed one prior platinum-containing line.
