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.
A new anti-HIV medicine (Dolutegravir) combined with 2 currently used anti-HIV medicines is non-inferior to the standard combination of medicines used in terms of efficacy and better in terms of toxicity.
This is an open-label, multicentre, 4-arm randomised phase II trial of fulvestrant + AZD2014 versus fulvestrant + everolimus versus fulvestrant alone in patients with ER-positive, HER2-negative advanced or metastatic breast cancer, whose disease relapsed during treatment with (or within 12 months after discontinuation of) an AI in the adjuvant setting or progressed during treatment with an AI in the metastatic setting. Patients will be randomised (2:3:3:2) to one of the four treatment arms: - Fulvestrant - Fulvestrant + AZD2014 (continuous daily schedule) - Fulvestrant + AZD2014 (intermittent schedule - 2 days on, 5 days off) - Fulvestrant + everolimus Randomization will be stratified by the following criteria: - Measurable disease (vs. non-measurable). - Sensitivity to prior endocrine therapy (sensitive versus resistant)
The purpose of this study is to find out whether either trastuzumab or the combination of trastuzumab and pertuzumab with standard chemotherapy shows more activity against gastro-oesophageal adenocarcinoma than standard chemotherapy given before and after surgery and it can be safely administered.
Primary Objective: To assess the effect of teriflunomide in comparison to placebo on disease activity measured by time to first clinical relapse after randomization in children and adolescents 10 to 17 years of age with relapsing forms of multiple sclerosis (MS). Secondary Objective: - To assess the effect of teriflunomide in comparison to placebo on disease activity/progression measured by brain magnetic resonance imaging (MRI) and on cognitive function. - To evaluate the safety and tolerability of teriflunomide in comparison to placebo. - To evaluate the pharmacokinetics (PK) of teriflunomide.
The purpose of this study is to determine if the addition of daratumumab to velcade (bortezomib) melphalan-prednisone (VMP) will prolong progression-free survival (PFS) compared with VMP alone in participants with previously untreated multiple myeloma who are ineligible for high dose chemotherapy and autologous stem cell transplant (ASCT).
The e-Ultimaster will further validate the safety and efficacy of Ultimaster DES system in unselected patients representing everyday clinical practice. Also the study will assess the impact of non-compliance with dual antiplatelet therapy, one month after stent implementation (frequently observed in every day clinical practice), on stent thrombosis.
The purpose of this study is to determine the effect of ixazomib citrate maintenance therapy on progression-free survival (PFS), compared to placebo, in participants with newly diagnosed multiple myeloma (NDMM) who have had a response (complete response [CR], very good partial response [VGPR], or partial response [PR]) to induction therapy followed by high-dose therapy (HDT) and autologous stem cell transplant (ASCT).
Older patients with acute myeloid leukemia (AML) have a small (< 10%) chance of long-term survival. Despite the treatment of elderly AML patients with intensive chemotherapy, the survival has not been improved during the last decades. The purpose of this study is to determine whether frontline therapy with a 10-day decitabine schedule provides a better survival than standard intensive combination chemotherapy in elderly AML patients (>= 60 years).
Observational study in the routine clinical practice setting to evaluate the short and long term safety profile of Radium-223 in metastatic castration resistant prostate cancer patients and to evaluate the risk of developing second primary cancers.
This is a registry study to evaluate the long-term safety and effectiveness of adalimumab in pediatric patients with moderately to severely active CD who are treated as recommended in the local product label.
