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 primary hypothesis is that computed tomography (CT) is superior to invasive coronary angiography (ICA) concerning the primary endpoint MACE (MACE = major adverse cardiovascular event; defined as at least one of the following: cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke) after a maximum follow-up of 4 years, in other words, that CT will result in a significantly lower rate of MACE. Secondary outcomes include MICE (MICE = minor cardiovascular events), procedural complications, cost-effectiveness, radiation exposure, cross-over to CT or ICA, gender differences, and health-related quality of life.
This study is being performed as a post-approval safety study (PASS), per the Pharmacovigilance Risk Assessment Committee (PRAC) of the European Medicines Agency (EMA), to gather data on Translarna (ataluren) safety, effectiveness, and prescription patterns in routine clinical practice.
The purpose of this study was to evaluate whether copanlisib in combination with rituximab is superior to placebo in combination with rituximab in prolonging progression free survival (PFS) in patients with relapsed iNHL who have received one or more lines of treatment, including rituximab and who either had a treatment-free interval of ≥ 12 months after completion of the last rituximab-containing treatment, or who are unwilling to receive chemotherapy/for whom chemotherapy is contraindicated on reason of age, comorbidities, and/or residual toxicity.
The study design is that of a cluster randomised controlled trial The aims of the study were: 1) to assess the quality of care of the residential units for people with long-term mental disorders; 2) to design a training intervention for the staff of the units in the intervention group; 3) to assess the effectiveness of the intervention 4 and 8 months after it ended. The main outcome variable was level of activity of the users. Secondary outcome variables were the QuIRC dimensions. The selection of the sample was by residential units for people with long-term mental disorders. The inclusion criteria were all the middle and high-support residential units in Portugal. Units that had only one type of service users (e.g., mental retardation, dementia) were excluded. The quality of care of the units was assessed with the QuIRC filled on line by the managers of the units and validated with Service Users Interview Schedule, a face-to-face interview with the users (users that could not give informed consent or collaborate in the interview were excluded).
The purpose of this study is to determine whether the BMS Attachment Inhibitor (BMS-663068) is effective in the treatment of heavily treatment experienced HIV-1 patients with multi-drug resistance.
A phase III multicenter, randomized study with Lenalidomide (Revlimid®) maintenance versus observation after intensified induction regimen containing rituximab followed by high dose chemotherapy and Autologous Stem Cell Transplantation as first line treatment in adult patients with advanced Mantle Cell Lymphoma: IIL study (MCL0208).
This is a single-arm, multi-center, open-label extension study designed to provide continued pertuzumab therapy to patients receiving pertuzumab as an investigational medicinal product (IMP) in a Roche-sponsored global study and who continue to receive pertuzumab at the end of the Parent study, as well as to collect long-term safety and efficacy data of pertuzumab therapy. Patients with solid tumors who have not experienced progressive disease in the Parent study and, in the investigator's opinion, may potentially benefit from continued pertuzumab treatment, will continue to receive pertuzumab until disease progression, unacceptable toxicity, investigator/patient decision, patient non-compliance, patient death, patient request to withdraw, or study termination by the Sponsor, whichever occurs first.
The best available evidence suggests that pregnancy after breast cancer does not increase a woman's risk of developing a recurrence from her breast cancer. In particular, the most recent data suggest that this is the case also in women with a hormone receptor-positive breast cancer. There is also no indication of increased risk for delivery complications or for the newborn. The aim of the study is to investigate if temporary interruption of endocrine therapy, with the goal to permit pregnancy, is associated with a higher risk of breast cancer recurrence.The study aims also to evaluate different specific indicators related to fertility, pregnancy and breast cancer biology in young women. A psycho-oncological companion study on fertility concerns, psychological well-being and decisional conflicts will be conducted in interested Centers.
The purpose of Phase 1b of this study is to: - Asses the safety, tolerability and activity of carfilzomib, alone and in combination with induction chemotherapy, in children with relapsed or refractory acute lymphoblastic leukemia (ALL). - Determine the maximum tolerated dose (MTD) and to recommend a phase 2 dose of carfilzomib in combination with induction chemotherapy. The purpose of Phase 2 of this study is to compare the rate of complete remission (CR) of carfilzomib in combination with vincristine, dexamethasone, PEG asparaginase, daunorubicin (VXLD) at the end of induction therapy to an appropriate external control.
To assess the efficacy and safety of AZD9291 versus a standard of care epidermal growth factor receptor tyrosine kinase inhibitor in patients with locally advanced or Metastatic Non Small Cell Lung Cancer
