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 objective is to assess the safety of the CardioKinetix Parachute Implant and Delivery System in the partitioning of the left ventricle in patients with heart failure due to ischemic heart disease.
The aim of the study is to asses the hydration status of incident peritoneal dialysis (PD) patients and its evolution over a period of four years, independent of the PD treatment modality (APD or CAPD) and the PD solution type.
The purpose of the study is to determine whether Ipilimumab plus Paclitaxel and Carboplatin will extend the lives of patients with squamous only non small cell lung cancer more than placebo plus Paclitaxel and Carboplatin.
The purpose of this study is to evaluate the safety and efficacy of S-1 and Cisplatin compared to 5-FU and Cisplatin in treatment of patients with metastatic diffuse gastric and gastro-esophageal junction cancer previously untreated with chemotherapy.
The purpose of the Multi-National Gilenya Pregnancy Exposure Registry in Multiple Sclerosis (MS) is to continuously monitor, evaluate, and assess for major and minor teratogenic effects in the offspring of women exposed to fingolimod before (up to 8 weeks before last menstrual period (LMP)) and during pregnancy in routine clinical practice. The overall aim is to collect and evaluate data on maternal, fetal, and infant outcomes and compare it with reference populations.
The drug being tested is called VigantOL® oil - a very effective form of Vitamin D hormone supplement (cholecalciferol). Low levels of Vitamin D have been described to be associated with a higher risk of developing Multiple Sclerosis (MS), and it is known that up to 90% of patients with Multiple Sclerosis have Vitamin D deficiency. Rebif® is known to be an effective treatment for slowing down the progression of MS. The purpose of this research trial is to evaluate if VigantOL® oil on top of Rebif® has any benefit on the progression of MS compared to Rebif® and placebo. Disease activity will be assessed by clinical examination and Magnetic Resonance Imaging (MRI). The planned study treatment duration for each study participant is 48 weeks, and the study consists of a total of 8 visits. Study participants who are already passed Week 48 at the time of approval of Protocol Amendment 5 will have a study duration of 96 weeks and a total of 12 visits. During the study, the participant will undergo physical examination, neurological assessments, safety assessments, blood tests and urinalysis (including pregnancy tests).
The primary objective of this retrospective study is to evaluate the percentage of patients with device related adverse events (infection, rejection, dislocation, fracture of the implant) in the first 24 months after implantation.
This trial is conducted in Europe. The aim of this trial is to evaluate the change in disease activity following 12 weekly s.c. (under the skin) doses of NNC109-0012 compared to placebo in subjects with active Rheumatoid Arthritis (RA).
This study explores the tolerability, safety and efficacy (i.e. how well the drug works) of flexibly dosed paliperidone palmitate in the treatment of schizophrenia in patients previously unsuccessfully treated with other oral or long-acting injectable (LAI) (i.e. with a long duration of action) antipsychotics.
