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.
Omalizumab will be given as add-on treatment to optimized asthma therapy in patients with severe persistent asthma, who demonstrate inadequate asthma symptom control. Response to omalizumab over time will be assessed by physicians and patients evaluating the overall improvement in control of their asthma. THIS STUDY IS NOT ENROLLING PATIENTS IN THE US.
Study hypothesis :Hyperbaric Oxygen may prevent complications and improve outcomes in severe lower limb trauma. We propose to investigate this hypothesis by conducting an International multi centre randomised control trial of standard trauma/orthopaedic care with or without a concurrent course of hyperbaric oxygen treatments.
RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Sometimes after treatment, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient. It is not yet known whether erlotinib is more effective than observation after first-line chemotherapy in treating patients with ovarian cancer, peritoneal cancer, or fallopian tube cancer. PURPOSE: This randomized phase III trial is studying erlotinib to see how well it works compared to observation in treating patients who have undergone first-line chemotherapy for ovarian cancer, peritoneal cancer, or fallopian tube cancer.
The primary objective of this trial is to demonstrate the efficacy and safety of dabigatran etexilate in patients with non-valvular atrial fibrillation for the prevention of stroke and systemic embolism.
The purpose of this study is to evaluate the effects of cinacalcet on markers of bone turnover in patients with kidney disease who are receiving dialysis.
Primary Objective: - Phase II: To determine the best treatment scheme (TPF vs. PF). - Phase III: To compare the time to progression and the treatment failure at the 3 arms. Secondary objectives: - To evaluate the safety at the 3 arms. - To compare the progression , overall survival and locoregional control at the 3 arms.
The purpose of this research study is to compare the efficacy of aripiprazole with placebo in combination with lithium or valproate monotherapy, in the treatment of bipolar I patients with manic or mixed episodes.
The purpose of this study is to determine the efficacy of anastrozole monotherapy versus maximal oestrogen blockade with combinated therapy of fulvestrant and anastrozole compared with in treatment of hormone receptor positive women with first relapse of breast cancer.
The purpose of the study is to evaluate the efficacy and safety of saredutant (or SR48968C) in patients with depression. The primary objective is to evaluate the efficacy of a 100 mg dose of saredutant compared to placebo in patients with depression. The secondary objectives are to evaluate the safety of saredutant, to evaluate the efficacy of saredutant on disability and quality of life in patients with depression, and to evaluate blood levels of saredutant.
The purpose of this study is to compare the changes in a proliferation biomarker in subjects receiving Anastrozole or Anastrozole/ZD1839 combination.
