There are about 1367 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.
- Introduction: The Cocaine Base Paste (or Coca Paste or CBP), a highly toxic and addictive smokable drug (a by-product of the cocaine extraction chain), has become in the last years a real social scourge for Chile. Today, there is not a pharmacological treatment approved in Chile neither around the world for the management of the withdrawal syndrome nor the dependence caused by the use of this substance. The N-Acetylcysteine (NAC), a derivative of the amino acid cysteine, with mucolytic and antioxidant properties, used in Chile since several years for bronchopulmonary treatments, as well as a hepatic and renal protector, among others, has shown, in animal and human research, that has benefits to reduce the craving for cocaine and in the management of the withdrawal syndrome of this and other psychoactive substances. - Objectives: To evaluate whether the use of NAC in patients with problematic CBP consumption reduce the craving for this substance and prolong its abstinence time. - Methods: will be carried out a randomized, double-blind, controlled, phase II-b clinical trial, with a parallel group design with CBP dependent patients in different outpatient care units in the province of Concepción, Chile. Patients who meet the cocaine (CBP) consumption disorder criteria, who have used of CBP within the last month and who have started to use it one year at least prior to admission to the study, will be selected from among the consulting population. Patients who agree to participate in the study must sign an informed consent form before being clinically evaluated. During the evaluations, semi-structured interviews and standardized questionnaires were used to investigate both consumption habits and symptoms of withdrawal and intensity of CBP craving, among others. All patients in the study will be attended twice weekly to treatment centers for four weeks, reporting their craving for CBP, the use of this substance (as well as urine tests), adverse reactions to the indicated medication, among others. - Expected results: It is expected that, thanks to the use of NAC, patients with CBP use disorder entered to this study significantly reduce their craving to consume this substance, they can prolong the abstinence time of it and they can reduce their falls in CBP consumption.
Patients who have shown previous implantation failures, despite transferring good quality and chromosomally normal embryos (diagnosed by PGT-A), could have a displaced Window of Implantation (WOI) and consequently, alterations in their endometrial receptivity. The correction of this displacement can improve the results of the Assisted Reproduction Treatments (ART). The ERA test (Endometrial Receptivity Analysis) evaluates the transcriptomic endometrial profile to determine if the patient's uterus is receptive when the embryo is transferred during an In Vitro Fertilization (IVF) process, and identifies the personalized WOI of the patient. This process is called Personalized Embryo Transfer (pET). The Preimplantation Genetic Test of Aneuploidies or PGT-A (Preimplantation Genetic Testing for Aneuploidy), is currently carried out using Next Generation Sequencing (NGS) and serves to identify chromosomally normal embryos prior to their transfer in an IVF treatment. Aneuploidies are rarely compatible with life or can cause congenital diseases. So, the identification of chromosomally normal embryos, improves the success of reproduction in cases in which infertility is caused by such aneuploidies. Therefore, the aim of this study is to determine, in a randomized and prospective way, the clinical benefit of adding the ERA test to the embryonic aneuploidies test for patients with a PGT-A indication.
This study will evaluate periodontal and systemic parameters of a cohort of chronic kidney disease (stage 5) patients, before and three months after non-surgical periodontal treatment. It does not consider a control group.
Background: Depression is prevalent and can have devastating effects on the life of adolescents. Computerized intervention programs for depression have shown positive results. There is less evidence in prevention and early treatment for depression in Latin American adolescents. Purpose: The purpose of this study is to determine whether a stepped internet-based program is effective to prevent and early intervene depression in adolescents attending 9th to 11th grade in eight schools in Santiago, Chile. Study design: A two-arm cluster-randomized clinical trial will be carried out with approximately 600 adolescents.
A study to evaluate Nivolumab or Nivolumab Plus Experimental Medication BMS-986205 with or without BCG in BCG-Unresponsive non-muscle invasive Bladder Cancer
Spontaneous breathing efforts in patients with respiratory failure connected to mechanical ventilation, has been associated with strong respiratory muscles activity. However, these mechanisms may will be present in patients with acute lung deseases who are breathing with no ventilatory support. We hypothesize that spontaneous breathing during acute respiratory failure could induced lung inflammation and worsen lung damage. Hereby, the connection to a ventilatory support tool, may protect the lungs from spontaneous ventilation-induced lung injury. To test our hypothesis, our aim is to determine the effects of spontaneous breathing in acute respiratory failure patients, on lung injury distribution; and to determine whether early controlled mechanical ventilation can avoid these deleterious effects by improving air distribution.
The purpose of this study is to evaluate the safety and effectiveness of the Levita Magnetic Surgical System in patients undergoing bariatric procedures
A study to investigate the safety and reactogenicity of MT-5625 independently in adults aged 18-35 years, toddlers ages 12-24 months, and infants aged 6-10 weeks
Despite exercise training decrease blood fasting glicaemy in 'average' terms, there is a wide inter-individual variability after exercise training explored mainly in adults but not in adults with prediabetes comorbidities. Thus, is yet unknown the effects and influence of the concurrent training (CT) eliciting responders (R) and non-responders (NR) cases (i.e., percentage of subjects who experienced a non-change/worsened response after training in some metabolic outcomes).
Hypothesis: Medication Review with follow-up can improve clinical, health related quality of life and economic outcomes. To prove this hypothesis a cluster randomized controlled trial will be held in primary care centres of the public health system of Chile. Patients of the cardiovascular disease prevention program, older than 60 years and with poly pharmacy (more than 5 drugs) will be recruited. Control group will receive usual care and the intervention arm will have medication review consultations by a pharmacist every 2 months for one year. Clinical interventions will be made with physician authorisation. Participating pharmacist will be trained in cardiovascular prevention pharmacotherapy in the elderly, interview skills and educational techniques. A practice change facilitator will assist the pharmacist in any matters regarding the methodology and will asses barriers and facilitators to the implementation of the medication review with follow-up service. A personalised plan will be developed for every pharmacist. Clinical outcomes (blood pressure, HbA1c, LDL cholesterol, overall cardiovascular risk, among others), number of medications, adherence rate and health related quality of life will be evaluated. A cost-utility analysis will be made through the health ministry of Chile point of view.
