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 aim of the present study is to investigate the safety of BI 10773 treatment in patients with Type 2 Diabetes Mellitus and high cardiovascular risk.
This study will assess tolerability and safety and health outcomes in relapsing MS patients taking FTY720.
Direct comparison studies of the tiotropium HandiHaler® 18 µg and Respimat® 5 µg formulations have been limited to 4-week crossover studies. Therefore, prospective data from a trial of adequate size and duration is required to establish that compared to tiotropium HandiHaler®, tiotropium Respimat® will have (a) similar effects on safety and (b) similar or superior effects on exacerbations.
To investigate the efficacy and safety of BIBW 2992 in combination with vinorelbine i.v. chemotherapy as treatment in patients with HER2-overexpressing, metastatic breast cancer, who failed one prior trastuzumab (Herceptin®) treatment
This study is designed as a phase III, randomized, double-blind, placebo-controlled trial to explore the effect of maintenance therapy with lenalidomide versus placebo on progression-free survival (PFS) in patients treated with R-CHOP responding to induction therapy For the primary efficacy variable, PFS, an improvement in median PFS from 38.6 months for Treatment Arm B to 54 months for Treatment Arm A (corresponding to a 2-year PFS of 65% vs 73.6%), is considered clinically relevant.
The purpose of this study is to investigate if treatment in erectile dysfunction with a long-acting drug (Tadalafil) taken once a day or taken as needed results in a longer treatment adherence and better long term outcomes (over 24 weeks), compared with a short-acting drug (Sildenafil Citrate) taken as needed.
This randomized, 3-arm, multicenter, phase III study will evaluate the efficacy and safety of trastuzumab emtansine (T-DM1) with pertuzumab or trastuzumab emtansine (T-DM1) with pertuzumab-placebo (blinded for pertuzumab), versus the combination of trastuzumab (Herceptin) plus taxane (docetaxel or paclitaxel) in participants with HER2-positive progressive or recurrent locally advanced or previously untreated metastatic breast cancer. Participants will be randomized to 1 of 3 treatment arms (Arms A, B or C). Arm A will be open-label, whereas Arms B and C will be blinded.
This randomized, blinded, parallel arm study evaluated the efficacy and safety of tocilizumab (RoActemra/Actemra) versus adalimumab as monotherapy in patients with rheumatoid arthritis who are intolerant of methotrexate or where continued treatment with methotrexate was considered inappropriate. Patients were randomized to receive either tocilizumab 8 mg/kg intravenously (iv) every 4 weeks plus placebo subcutaneously (sc) every 2 weeks, or adalimumab 40 mg sc every 2 weeks plus placebo iv every 4 weeks. Treatment was anticipated to last 24 weeks. With regard to the blind, the study nurse was unblinded due to the nature of the treatment administration, but the investigator and the patient remained blinded.
The purpose of this study is to determine whether an early Calcineurin Inhibitor (CNI) to everolimus conversion at 10-14 weeks post transplantation improves renal allograft function without compromising efficacy compared to standard CNI treatment in de novo renal allograft recipients. In addition, the study is designed to evaluate the impact of a CNI-free regimen on evolution of cardiovascular parameters in de novo renal allograft recipients
This study is designed to evaluate the safety and efficacy of a regimen containing Cobicistat (COBI)-boosted atazanavir (ATV/co) plus emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) versus ritonavir (RTV)-boosted atazanavir (ATV/r) plus FTC/TDF in HIV-1-infected, antiretroviral treatment-naive adults. Development of COBI as a "pharmacoenhancer" could provide a beneficial alternative to RTV for use in combination with protease inhibitors.
