There are about 167 clinical studies being (or have been) conducted in Costa Rica. 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.
Background: Cervical cancer is a dangerous disease caused by a germ called human papillomavirus (HPV). There are 3 safe vaccines that protect women against HPV and cancer. Currently, girls receive 2 doses of HPV vaccine. Researchers want to test if only 1 dose is enough. This study in Costa Rica is one of several new 1-dose studies being done around the world. Objective: To find out if giving only 1 dose of the HPV vaccine Cervarix to young girls works the same as giving 3 doses of the HPV vaccine Gardasil to young women. Eligibility: Healthy girls ages 9-14 Healthy women ages 18-25 Design: Participants will be screened with blood and urine tests and questions about their health. Their parents may answer some of the questions. Participants will get the vaccine as an injection in the arm. They will be observed for 15 minutes each time they get the vaccine. Participants ages 9-14 will get the Cervarix vaccine 1 time. Six months later, participants (or their parents) will be asked about their health. This contact will be a phone call and will take about 5 minutes. Participants ages 18-25 will get the Gardasil vaccine 3 times over 6 months. All participants will have 1 half-hour visit every year for 3 years after getting the vaccine. This can be at the clinic or the participant s home. Participants and/or their parents will answer questions about the participant s health and any vaccines they received since the last contact. Participants will give a blood sample.
This study will evaluate the safety, pharmacokinetics and efficacy of baloxavir marboxil in healthy pediatric participants from birth to <1 year with influenza like symptoms
This study will evaluate the safety, pharmacokinetics, and efficacy of baloxavir marboxil compared with oseltamivir in a single influenza episode in otherwise healthy pediatric participants (i.e., 1 to <12 years of age) with influenza-like symptoms.
To provide real world data on patient characteristics, disease management, healthcare utilization, and outcomes in patients with type 2 diabetes and established micro- and/or macrovascular disease
This study is a prospective, multicenter, open-label, single-arm effectiveness and safety study in participants with progressive multiple sclerosis (PMS).
The study develops, implements, and evaluates an intervention focused on alleviating discouragement, food insecurity, and excess weight in women,targeted at the individual, family, and community levels in the Canton Central of the province of Alajuela, Costa Rica.
The main objectives of this observational cohort study are to describe the use of intravitreal aflibercept and to describe follow-up as well as treatment patterns in patients with wAMD or DME in routine clinical practice in Latin America for a study population of treatment naive patients and those who have received prior therapy (anti-VEGF injections, laser, steroids, etc.) and are being switched to intravitreal aflibercept injection.
This study will evaluate the efficacy of ipatasertib + paclitaxel versus placebo + paclitaxel in participants with histologically confirmed, locally advanced or metastatic triple-negative breast cancer (TNBC) and in participants with locally advanced or metastatic hormone receptor positive (HR+)/ human epidermal growth factor receptor 2 negative (HER2−) breast adenocarcinoma who are not suitable for endocrine therapy.
Background: HPV is the human papillomavirus. Women who get infected with it can get cervical cancer. The Costa Rica vaccine trial (CVT) studied an HPV vaccine for young women. A Long Term Follow Up (LTFU) study was done 10 years later. Researchers want to follow up with the women in these studies for 5 more years. This will help them learn more about the risks and benefits of the HPV vaccine. Objectives: To study anti-HPV-16/18 antibodies over the long term in women who got an HPV vaccinate. To study how antibody levels have changed depending on the dose and type of vaccine. Eligibility: Women in the original CVT LTFU study Design: Staff will contact participants from the CVT LTFU study. This will be done by phone or in person at home. Participants will be asked about participating in a new study. Participants who agree will have their first study visit and sign the informed consent document. Participants will answer questions about sexual behavior, smoking, contraceptives, and reproductive history. Participants will have blood collected. Study visits will be conducted either in a clinic or at home.
This observational case-control trial sought to identify and characterize different exposures associated with nonfatal acute myocardial infarction in Costa Rican adults. Exposures assessed included dietary variables and adipose tissue fatty acids.
