There are about 4010 clinical studies being (or have been) conducted in Argentina. 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.
Infertility is considered a disease by the World Health Organization and it is increasing worldwide affecting more than 70 million couples. About 50% of the cases are due to male inability to fertilize the oocyte. In the last 40 years, several techniques, known as Assisted Reproduction Technology (ART) have been developed to treat infertility, but the efficiency is still relatively low (around 30%) whereas the remaining 70% attempts again several times, an expensive and emotionally moving treatment. Over 4million of infertility treatments are practiced around the world per year and a 50% increment is expected over the next 6years. Even though ART allows the birth of babies that would be impossible under natural circumstances, it is still necessary to improve the procedures in order to increase treatment efficiency. The success of ART depends, to some extent, on sperm quality. Indeed, the relevance of spermatozoa quality is notorious even beyond fertilization, extending to embryo development and implantation. In this context, it has been developed a new technology that allows the selection of those spermatozoa at their best functional state (Sperm Selection Assay, SSA; Patent approved for USA and Europe, pending for Japan and Argentina). This method is based on the attraction of spermatozoa ready to fertilize the egg, towards a physiological attractant molecule. The SSA may be applied to improve diagnosis and infertility treatment. The investigators hypothesis states that the use of the SSA will improve the number of good-quality embryos which are the ones to be transferred by intracytoplasmic sperm injection (ICSI), providing a healthy embryo development. The protocol involves three experimental groups where the SSA will be used or not, before performing the ICSI: 1)SSA containing the sperm attractant molecule, 2)SSA without the attractant molecule, and 3)without SSA. The patient inclusion criteria involve female factors associated to tubal obstruction and/or endometriosis and male factors associated to sperm disability. Several outcome parameters will be determined, the percentage of fertilization, embryo quality, rate of pregnancy and rate of birth. The study will be carried out in the Universitarian Institute of Reproductive Medicine (IUMER) which has been recently established in a public hospital depending on the National University of Córdoba, offering free high complexity infertility treatment to patients without health insurance or economic support
The purpose of the study is to develop a prognostic index model for the rare disease of mycosis fungoides and sezary syndrome. This will be done by collecting standardized clinical data at various institutions. The investigators hope this will enable the identification of low- and high-risk groups for survival in order to improve patient care and outcome.
The Institutional Registry of Liver Transplantation is a system for data collection related to patients with liver disease who are possible candidates for liver transplantion. This tool was designed by a multidisciplinary team that includes hepatologists, surgeons, informatics and biostatisticians. It intends to collect the information from the clinical evaluation, physical examination, complementary diagnostic methods and laboratory data. The information is captured sistematically, following structured, standardized and monitored processess to ensure the quality of the data obtained. The aim is to use the available technology to generate a complete database that can be used to answer research questions.
The Computerized Registry of Patients with Venous Thromboembolism (RIETE) is a multidisciplinary Project initiated in march 2001 and consisting in obtaining an extensive data registry of consecutive patients with venous thromboembolism. The main objective is to provide information on the Internet to help physicians to improve their knowledge on the natural history of thromboembolic disease, particularly in those subgroups of patients who are usually not recruited in randomized clinical trials (pregnant women, elderly patients, disseminated cancer, severe renal insufficiency, patients with contraindications to anticoagulation therapy, extreme body weight, etc), with the purpose of decreasing mortality, frequency of thromboembolic recurrences as well as bleeding complications and arterial events. As an additional objective RIETE is also aimed to create predictive scores that help physicians to better identify patients with high risk of presenting some of these complications. The primary parameters recorded by the registry comprise details of each patient's clinical status, including any coexisting or underlying conditions, and the type, dose, duration and outcome (during the first 3 months of therapy) of antithrombotic treatment. Study endpoints are clinically recognized (and objectively confirmed) recurrences of VTE, major and minor bleeding complications, and death.
The Aims of the study are estimate the association between the severity of COPD and free testosterone level and the prevalence of hypogonadism in adult men with stable COPD
This is a Registry that invites patients undergoing colorectal surgery for colorectal cancer. Epidemiological data is collected. The Registry includes tumor tissue and blood banks for analyzing different genetic mutations and disease-specific biomarkers.
The aim of the study is to test whether a resource-sparing 4-week, 20-fraction course of accelerated hypofractionated radiotherapy is non-inferior to accelerated radiotherapy delivering 33 fractions over 5.5 weeks in the treatment of patients with Stage I-IV squamous cell carcinoma of the pharynx, larynx and oral cavity with the exception of paranasal sinus, nasopharyngeal and stage I-II glottic carcinomas.
The aim of the study is to estimate the prevalence of respiratory aspiration in patients with COPD, in a tertiary hospital of Buenos Aires.
This is a multi-center, open-label, first-in-human Phase 1 study evaluating the anti-programmed death receptor 1 (anti-PD-1) antibody dostarlimab (also known as TSR-042) n participants with advanced solid tumors who have limited available treatment options. The study will be conducted in 2 parts with Part 1 consisting of safety evaluation, pharmacokinetics (PK), and pharmacodynamics (PDy) of escalating doses of dostarlimab. Dose escalation will be based on ascending weight-based dose levels (DLs) of dostarlimab and will continue until the maximum tolerated dose (MTD) is reached or may be stopped at any dose level up to the highest dose of 20 milligrams per kilograms (mg/kg) based on emerging safety and PK/PDy data. Part 2 will be conducted in two subparts, Part 2A (fixed-dose safety evaluation cohorts) and Part 2B (expansion cohorts). Part 2A of the study will evaluate the safety and tolerability of dostarlimab at fixed doses of 500 mg administered every 3 weeks (Q3W) and 1000 mg administered every 6 weeks (Q6W). Part 2B of the study will examine the safety and clinical activity of dostarlimab in cohorts of participants with specific types of advanced solid tumors.
The purpose of this study is to create an institutional registry of Chronic Obstructive Pulmonary disease through a prospective survey based on epidemiological data, risk factors, diagnosis, prognosis, treatment, monitoring and survival.
