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 evaluate the effect of bariatric surgery in bile acid homeostasis and its interrelationship with the metabolic changes induced by the surgery. This study contemplates the following hypothesis: - Bariatric Surgery induce a new study state in bile acid homeostasis with higher bile acid synthesis in association with increased bile acid content. - The major effects of bariatric surgery on bile acid synthesis and is observed one month after surgery with a progressively decline during the first year of follow-up. - Gastric bypass increases serum bile acid content, postprandial plasma bile acid response and fecal bile acid excretion. - Serum bile acids changes induced by gastric bypass are positively correlated with changes in gastric inhibitory polypeptide (GIP) levels and postprandial concentration of insulin and glucagon like peptide-1 (GLP-1) and inversely correlated with thyrotropic hormone (TSH) and postprandial concentration of glucose. - Changes in postprandial plasma bile acid response induced by gastric bypass positively correlates with changes in postprandial concentration of insulin, GLP-1 and peptide YY (PYY) and inversely correlates postprandial response of ghrelin and glucose.
This randomized, open-label study evaluated the safety and efficacy of atezolizumab (an engineered anti-programmed death-ligand 1 [PD-L1] antibody) in combination with carboplatin+paclitaxel with or without bevacizumab compared with treatment with carboplatin+paclitaxel+bevacizumab in chemotherapy-naïve participants with Stage IV non-squamous NSCLC. Participants were randomized in a 1:1:1 ratio to Arm A (Atezolizumab+Carboplatin+Paclitaxel), Arm B (Atezolizumab+Carboplatin+Paclitaxel+Bevacizumab), or Arm C (Carboplatin+Paclitaxel+Bevacizumab).
This is a multinational, double-blind, randomized, parallel-group Phase 3 clinical trial evaluating the efficacy and safety of bevacizumab-Pfizer plus paclitaxel and carboplatin versus bevacizumab-EU plus paclitaxel and carboplatin in first-line treatment for patients with advanced (unresectable, locally advanced, recurrent or metastatic) non-squamous NSCLC.
The purpose of this study is to determine whether the BMS Attachment Inhibitor (BMS-663068) is effective in the treatment of heavily treatment experienced HIV-1 patients with multi-drug resistance.
Demineralisation and white-spot caries often occures during MB treatment. While resin infiltration has been proved to stop progression of enamel demineralisation, there is still a paucity of information in the literature concerning the best time point of infiltration: During or following MB treatment. Infiltration during treatment requires debonding respective brackets prior to infiltration, with subsequent re-bonding. In terms of preventing enamel damages by progression of demineralisation and enamel damages by de-bonding, it is unclear whether it was better to infiltrate enamel immediately, or to better postpone until completion of MB treatment. This study thus aimes to evaluate if resin infiltration can prevent enamel damage due to bracket de-bonding.
This study is a Phase III, randomised, open label, multi-centre study assessing the efficacy and safety of MEDI4736 (durvalumab) versus Standard of Care in NSCLC patients with PD-L1 positive tumours and the combination of MEDI4736 (durvalumab) plus tremelimumab (MEDI4736+treme) versus Standard of Care in NSCLC patients with PD-L1-negative tumours in the treatment of male and female patients with locally advanced or metastatic NSCLC (Stage IIIB-IV), who have received at least 2 prior systemic treatment regimens including 1 platinum-based chemotherapy regimen for NSCLC. Patients with known EGFR (Epidermal growth factor receptor) tyrosine kinase (TK) activating mutations and anaplastic lymphoma kinase (ALK) rearrangements are not eligible for the study (prospective testing is not planned within this study). The Standard of Care options are: an EGFR tyrosine kinase inhibitor (erlotinib [TARCEVA®]), gemcitabine or vinorelbine (NAVELBINE®)
Primary Objective: To evaluate, in comparison with placebo, the efficacy of 2 dose levels/regimens of SAR156597 administered subcutaneously during 52 weeks on lung function of participants with Idiopathic Pulmonary Fibrosis (IPF). Secondary Objectives: To evaluate the efficacy of 2 dose levels/regimens of SAR156597 compared to placebo on IPF disease progression. To evaluate the safety of 2 dose levels/regimens of SAR156597 compared to placebo in participants with IPF.
It is of clinical importance to arrest the development of approximal caries at an early stage. The potential for initial caries to develop into manifest lesions has motivated studies on the use of sealants to arrest the progression of caries on both occlusal and approximal tooth surfaces. Therefore, the aim of the present study was to follow-up and examine after 3.5 years, the efficacy of sealing caries-free or non-cavitated mesial surfaces of first permanent molars abutting lesions on the distal surfaces of second primary molars. The null hypothesis tested here was that preventive and therapeutic sealants do not prevent the development or slow the progression of dental caries over a period of 3.5 years in comparison to non-sealed control surfaces.
This study evaluates the effectiveness of maternal supplementation with Docosahexaenoic acid (DHA) early in pregnancy to reduce the incidence of deep placentation disorders: preterm birth, preterm labor, preterm premature rupture of membranes, preeclampsia and fetal growth restriction. Half of the participants in early pregnancy will receive DHA 600 mg per day, while the other half will receive placebo. Investigators will study also the ability of DHA supplementation, early in pregnancy, to enhance invasion and transformation of spiral arteries by trophoblast, as deep placentation indicators.
Primary Objective: To demonstrate that sarilumab monotherapy was superior to adalimumab monotherapy with respect to signs and symptoms as assessed by disease activity score 28 (DAS28)-erythrocyte sedimentation rate (ESR) in participants with active rheumatoid arthritis (RA) who were either intolerant of, or considered inappropriate candidates for continued treatment with methotrexate (MTX), or after at least 12 weeks of continued treatment with MTX, were determined to be inadequate responders. Secondary Objectives: To demonstrate that sarilumab monotherapy was superior to adalimumab monotherapy in participants with active RA who were either intolerant of, or considered inappropriate candidates for continued treatment with MTX, or after at least 12 weeks of continued treatment with MTX, were determined to be inadequate responders, with respect to: - Reduction of signs and symptoms of RA. - Improvement in quality of life assessed by participant reported outcome questionnaires. Assessment of the safety and tolerability of sarilumab monotherapy (including immunogenicity) throughout the study.
