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.
After liver transplantation one of the most important cost, for both patients and their health insurance system, is immunosuppressive drug therapy. Tacrolimus (FK 506) is considered the cornerstone of immunosuppressive therapy in solid organ transplantation. Oral administration is the usual route, however, sublingual (SL) administration has been recently reported. This method of administration avoids first pass metabolism and allows an alternative route after transplant surgery, particularly in those patients who should extend the period of fasting (prolonged intubation, ileus, etc). Interestingly, in some studies, the dose of tacrolimus SL required to maintain similar plasma concentrations compared with oral administration, is significantly lower, even up to 50%, which can result in considerable savings in short and long term. Among these studies, only one was conducted in liver recipients. This study suggest that SL administration of tacrolimus could allow to obtain similar concentrations compared with oral administration. The design of this study did not assess the existence of differences in the dose required and only included six patients.
Psychological First Aid (PFA) is currently the most recommended early intervention for people affected by recent traumatic events, especially in the aftermath of natural disasters. Unfortunately, there is no evidence that PFA neither prevents Post-Traumatic Stress Disorder (PTSD) nor other post-traumatic disorders or symptoms of distress. This project aims to evaluate the efficacy and safety of Psychological First Aid for the prevention of PTSD and other post-traumatic disorders or symptoms.
58 patients between 18 and 76 years who attended the Operative Dentistry Clinic at Dental School, Universidad de Chile, were included in the study. Those patients were bleaching and included in this study and signed a consent form. The patients were treated with 10% carbamide peroxide (CP) gel (Whiteness Perfect, FGM) to each subject with verbal instructions for 3 weeks with daily applications of 1 hour according to manufacturers indications , before and after this procedure was applied again the OHIP-Esthetics , PIDAQ and OES questionnaire form, had 30 minutes to answer it, were completed before , immediately after and one month control post-bleaching procedure.
The purpose of this clinical study was to evaluate, the effectiveness and sensitivity post-treatment of a 6% hydrogen peroxide with nitrogen-doped titanium dioxide light activated bleaching agent, the impact of shorter interval times on tooth sensitivity and to compare the efficacy with 2 different application protocols. This is a clinical randomized double-blind split-mouth study. 31 patients were treated with: one upper hemi arcade with one application of 36 minutes and the other hemi arcade with 3 applications of 12 minutes each with a 6% hydrogen peroxide. Two sessions were appointed with 48h of intervals between them. Tooth colour was registered by VITA Classical amd VITA Bleach guide by two blinded assessors in the beginning, immediately after each session. Tooth colour variation and sensitivity were compared between both application protocols
This is a multicenter, randomized, double-blind study of the efficacy and safety of iclaprim compared to vancomycin for the treatment of skin and skin structure infections.
Systemic Sclerosis (SSc) is a devastating disease of unknown etiology. Patients suffer from multiple organ fibrosis whereas lung fibrosis (interstitial lung disease, ILD) is one of the main driver for mortality. There is preclinical evidence for efficacy of nintedanib in SSc and associated ILD (SSc-ILD) and the anti-fibrotic efficacy of nintedanib was proven in idiopathic pulmonary fibrosis patients, who are presenting a similar pattern regarding lung fibrosis. Hence it is the purpose of the trial to confirm the efficacy and safety of nintedanib 150 mg bid in treating patients with SSc-ILD, compared with placebo. The trial will be conducted as a double blind, randomised, placebo-controlled trial with primary efficacy evaluation at week 52 and placebo-controlled treatment until last patient out (up to a maximum of 100 weeks). Respiratory function is globally accepted for assessment of treatment effects in patients with lung fibrosis. The chosen endpoint (Forced Vital Capacity (FVC) decline) is easy to obtain and is part of the usual examinations done in patients with SSc-ILD.
RE-COVERY is a large, multi-national, multi-center observational study based on new data collection. The study will enroll and characterize patients within 30 days of being diagnosed with an acute DVT and/or PE. The study has two main objectives. Objective 1 will characterize the DVT / PE patient population. All patients with a DVT and/or PE will be enrolled for cross-sectional characterization of the VTE patient population. Objective 2 will compare the safety and effectiveness of dabigatran etexilate regimens for treatment of VTE in comparison to VKA regimens. Patients treated with dabigatran etexilate or VKA will be followed up for the occurrence of outcome events for up to one year.
The clinical characteristics, initial presentation, management, and outcomes of patients hospitalized with new-onset (first diagnosis) heart failure (HF) or decompensation of chronic HF are poorly understood worldwide. REPORT-HF is a global, prospective, and observational HF disease registry designed to characterize patient trajectories longitudinally during and following an index hospitalization for acute HF.
To determine the safety and tolerability of Oraxol as compared to IV paclitaxel in metastatic breast cancer
The overall aim of this pilot study is to evaluate the acceptability and feasibility of an adaptation of Beardslee's 'Preventive Intervention Program (PIP) for Depression' in Chilean families. The PIP is a family intervention directed towards strengthening family functioning and enhancing resilience in children of depressed parents. It comprises several modules that work on psycho-education and skill development within the family nucleus. A single-blind randomized controlled trial will be conducted with two arms, the intervention arm (n=32) which will receive a home-based PIP for depression, and the TAU arm (n=32).
