There are about 2320 clinical studies being (or have been) conducted in Chile. 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 purpose of this study was to evaluate the effect of a integrated system for inserting two splinted minimally-invasive implants, to retain mandibular over dentures, on the quality of life of edentulous patients.
This is a multi-centered, randomized, placebo-controlled, double-blind, parallel group, trial evaluating 2 doses of mepolizumab against placebo given every 4 weeks through subcutaneous (SC) injection. In severe COPD subjects, sputum eosinophils levels are elevated to similar levels as those seen in severe asthmatics. It is hypothesized that the reduction of eosinophils with mepolizumab in COPD subjects would translate into a reduction of COPD exacerbations. The study will evaluate the efficacy and safety of mepolizumab, in subjects who are at or above the baseline blood eosinophil count of at least 150 cells/microliters who exacerbate despite regular use of maximal tolerated therapy, appropriate for severe COPD subjects, in the 12 months prior to study start. In total, 660 subjects will be randomized in 1:1:1 ratio to receive mepolizumab 300 mg, mepolizumab 100mg, or placebo administered SC. The total duration of subject participation will be approximately 62 weeks, consisting of a 1 to 2 week screening period, 52-week treatment period and 8-week follow-up period.
Pulmonary artery hypertension (PAH) is a chronic and progressive disease that affects 15 persons per million. Although current therapy has improve disease prognosis, PAH still has a poor survival, with a median survival of 2.8 years after diagnosis. In the last few years new key elements in PAH pathogenesis have been discovered, such as the role of metabolism in disease onset and progression. In fact, PAH pulmonary smooth muscle cells switch into a glycolytic phenotype which resembles the metabolism of cancer cells. The investigators hypothesis is that "fatty acid oxidation inhibition reverts the PAH adverse phenotype by restoring mitochondrial function and morphology, decreasing proliferation and restoring apoptosis susceptibility in pulmonary smooth muscle cells "
The objectives of this study and registry are to offer the best management possible for patients with brain arteriovenous malformations (AVMs) (ruptured or unruptured) in terms of long-term outcomes, despite the presence of uncertainty. Management may include interventional therapy (with endovascular procedures, neurosurgery, or radiotherapy, alone or in combination) or conservative management. The trial has been designed to test a) whether medical management or interventional therapy will reduce the risk of death or debilitating stroke (due to hemorrhage or infarction) by an absolute magnitude of about 15% (over 10 years) for unruptured AVMs (from 30% to 15%); and, b) to test if endovascular treatment can improve the safety and efficacy of surgery or radiation therapy by at least 10% (80% to 90%). As for the nested trial on the role of embolization in the treatment of Brain AVMs by other means: the pre-surgical or pre-radiosurgery embolization of cerebral AVMs can decrease the number of treatment failures from 20% to 10%. In addition,embolization of cerebral AVMs can be accomplished with an acceptable risk, defined as permanent disabling neurological complications of 8%.
This post-marketing study is designed to compare the safety of tofacitinib versus TNF inhibitor with respect to major cardiovascular adverse events and malignancies, excluding non-melanoma skin cancers when given to subjects with rheumatoid arthritis. Other safety events, including non-melanoma skin cancers, hepatic events, infections, and efficacy parameters will be collected and evaluated in the study.
The primary objective of this study is to obtain long term safety data of ataluren in male participants with nonsense mutation dystrophinopathy (who participated and completed a previous Phase 3 study of ataluren [PTC124-GD-020-DMD {NCT01826487}]) to augment the overall safety database. Screening and baseline procedures are structured to avoid a gap in treatment between the double-blind study (PTC124-GD-020-DMD) and this extension study. This study may be further extended by amendment until either ataluren becomes commercially available or the clinical development of ataluren in duchenne muscular dystrophy (DMD) is discontinued.
To evaluate the long-term safety and tolerability of idalopirdine (Lu AE58054) as adjunctive therapy to donepezil in patients with mild-moderate Alzheimer's Disease (AD).
This randomized, active controlled, multicenter phase III open-label study is designed to evaluate the efficacy and safety of alectinib compared with crizotinib treatment in participants with treatment-naive anaplastic lymphoma kinase-positive (ALK-positive) advanced non-small cell lung cancer (NSCLC). Participants will be randomized in a 1:1 ratio to receive either alectinib, 600 milligrams (mg) orally twice daily (BID), or crizotinib, 250 mg orally BID. Participants will receive treatment until disease progression, unacceptable toxicity, withdrawal of consent, or death. The study is expected to last approximately 144 months.
- Assess the effectiveness of sealing localized marginal defects of amalgam restorations that were initially scheduled for replacement of restorations. - The hypothesis was that sealed defective margins of the amalgam restorations shows similar performance than replacement amalgam restorations.
The purpose of this trial is to confirm if benralizumab can reduce the use of maintenance OCS in systemic corticosteroid dependent patients with severe refractory asthma with elevated eosinophils.
