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.
To evaluate the safety and determine the efficacy of PRP monotherapy or combination therapy (pegaptanib 0.3 mg plus PRP) in patients with Type I or Type II diabetes mellitus and with high risk proliferative diabetic retinopathy.
The purpose of this trial is to evaluate safety and to compare the efficacy of intravitreous injection of ranibizumab alone (0.5 mg), versus combination of intravitreous injection of ranibizumab (0.5 mg) plus panretinal photocoagulation, versus panretinal photocoagulation alone in the regression of retinal neovascularization in eyes with high-risk proliferative diabetic retinopathy.
This study will assess the efficacy of 8 months treatment of Sandostatin® LAR® High Dose monotherapy or Sandostatin® LAR® High Dose in combination either with growth hormone antagonist or dopamine agonist to control biochemical parameters (GH and insulin-like growth factor I [IGF I]) of acromegalic patients not achieving biochemical normalization at conventional regimen.
This study will evaluate the safety and efficacy of tenofovir disoproxil fumarate (TDF) plus peginterferon α-2a (PEG) combination therapy versus standard of care TDF monotherapy or PEG monotherapy in non-cirrhotic adults with chronic hepatitis B virus (HBV). The study will consist of 2 phases for participants in the TDF+PEG 48 week, TDF 48 week+PEG 16 week, and PEG 48 week groups. Following an initial 48 weeks of treatment, participants in these groups will be monitored for 24 weeks for signs of worsening HBV, and those with new signs and/or symptoms will be eligible to receive TDF monotherapy during a retreatment phase, up to Week 120.
The overall purpose of the trial is to evaluate efficacy and safety of tiotropium inhalation solution delivered via Respimat® inhaler (2.5 mcg and 5 mcg once daily) over 12 weeks, compared to placebo, as add-on controller therapy on top of usual care in adolescents (12 to 17 years old) with severe persistent asthma. The primary objective of the trial is to demonstrate superiority of tiotropium (5 mcg and possibly 2.5 mcg once daily in the evening) over placebo with regard to the primary pulmonary function endpoint after 12 weeks of treatment. Secondary objectives are to evaluate efficacy of tiotropium with regard to other endpoints, and to evaluate the safety of tiotropium, compared to placebo, as add-on controller therapy on top of usual care in this patient population.
This Phase 3 study will evaluate the efficacy and safety of 2.0 mg/kg/week BMN 110 and 2.0 mg/kg/every other week BMN 110 in patients with mucopolysaccharidosis IVA (Morquio A Syndrome). There is currently no standard accepted treatment for MPS IVA other than supportive care. Enzyme replacement therapy (ERT) may be a potential new treatment option for MPS IVA patients. BMN 110 is administered to MPS IVA patients by IV infusion, allowing cellular uptake by the mannose-6-phosphate receptor and transportation to the lysosomes. This enzyme uptake into the lysosomes is hypothesized to promote increased catabolism of keratan sulfate (KS) in tissue macrophages, hyaline cartilage, other connective tissues, and heart valve, and reduce the progressive accumulation of KS which is responsible for the clinical manifestations of the disorders.
Primary Objective: - To demonstrate the efficacy of at least one dose of SAR110894 (H3 receptor antagonist) in comparison to placebo on cognitive performance in patients with mild to moderate Alzheimer's disease (AD) while on stable donepezil therapy Secondary Objectives: - To explore the effect of SAR110894 on functional impairment, global clinical status and behavioral disturbances; - To assess the safety/tolerability of SAR110894; - To assess pharmacokinetic (PK) of SAR110894 and concentrations of donepezil; - To explore caregiver time consumption and distress changes.
This is a non-interventional, prospective, longitudinal cohort study. A total of 150 pediatric subjects with glaucoma or elevated intraocular pressure, including 75 latanoprost-treated subjects and 75 non-topical prostaglandin analogue treated subjects, will be enrolled from ophthalmic hospital clinics and academic ophthalmic centers. As a non-interventional study, the study subjects' continued use of latanoprost and assessments of ocular events will be obtained through the routine medical follow-up with treating ophthalmologists or other designated members of the medical care team.
The purpose of this study is to evaluate how well a new drug called Dysport NG works and how safe it is, when it is used for the treatment of cervical dystonia. Dysport NG will be compared to an approved drug called Dysport.
This single arm, open-label study will evaluate the efficacy and safety of erlotinib (Tarceva) in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations.
