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 is to compare the safety and efficacy of the Ahmed valve and the Baerveldt implant in treating refractory glaucoma. Eligible patients will be recruited from multiple study centers and randomized to a glaucoma drainage device for implantation. They will be followed long-term based upon outcome measures including intraocular pressure, glaucoma medication use, visual acuity, complications of the surgery and further treatments required.
The aim of this study is to demonstrate that clazosentan, administered as a continuous intravenous infusion at either 5 mg/h or 15 mg/h until Day 14 post aneurysmal subarachnoid hemorrhage (aSAH), reduces the incidence of cerebral vasospasm-related morbidity and all-cause mortality within 6 weeks post-aSAH treated by endovascular coiling. The primary endpoint of the study is the occurrence of cerebral vasospasm-related morbidity, and mortality of all-causes within 6 weeks post-aSAH, defined by at least one of the following: 1. Death (all causes). 2. New cerebral infarct(s) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 3. Delayed ischemic neurological deficit (DIND) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 4. Administration of a valid rescue therapy in the presence of confirmed cerebral vasospasm on angiography (DSA or CTA). An independent Critical Events Committee (CEC) will adjudicate whether or not patients meet the primary endpoint and its individual morbidity components.
This study is aimed at assessing the safety and immunogenicity of different doses and formulations of a new Novartis Meningococcal B Recombinant Vaccine.
Peritoneal metastases appear in a great proportion of patients affected by gastric carcinoma. Involved mechanisms are poorly understood though experimentally it has been demonstrated that neoplastic cells exfoliated from primary tumor can only implant and proliferate in areas of damaged peritoneum. Objectives: to study ultra-structure of peritoneal surface by electronic microscopy in control subjects and in patients with early or locally advanced gastric cancer looking for spontaneous changes in peritoneal surface not related with surgical injury.
The investigators hypothesize that following virological failure of a standard NNRTI+2N(T)RTI regimen second-line antiretroviral therapy consisting of ritonavir-boosted lopinavir and 2N(T)RTIs will offer comparable efficacy to that provided by ritonavir-boosted lopinavir and raltegravir. The study will be conducted for 96-weeks with the primary endpoint analyzed after 48-weeks. The primary endpoint is virological: a comparison of virological suppression in plasma < 200 copies/mL between the randomized arms after 48 weeks. Secondary and exploratory endpoints include virological, immunological, safety, clinical, metabolic, drug adherence, drug resistance and quality of life.
The purpose of this study is to evaluate the effects of PF-04447943 compared to placebo on cognitive, behavioral and overall symptoms of Alzheimer's disease; evaluate the safety and tolerability of PF-0444793 compared to placebo; and determine the levels of PF-04447943 in the plasma over the course of the study.
The purpose of this study is demonstrate that subcutaneous abatacept is non-inferior (no worse than) to subcutaneous adalimumab in the treatment of subjects with rheumatoid arthritis who are biologic naive
This study was designed to investigate the 1 year efficacy and safety of the 50 µg once daily (od) dose of glycopyrronium bromide (NVA237) in patients with moderate to severe chronic obstructive pulmonary disease.
To demonstrate if once-daily dosing of ADVAIR 100/50 once-daily has superior efficacy and comparable safety compared with FP 100mcg once-daily in pediatric subjects 4 to 11 years of age with asthma.
The study is designed to demonstrate that axitinib (AG-013736) is superior to sorafenib in delaying tumor progression in patients with metastatic renal cell cancer.
