There are about 211 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.
Early diagnosis of LC in the asymptomatic stage through intentional screening programs and/or incidental pulmonary nodule identification and follow-up are known to improve outcomes significantly. There are large gaps in the screening and early detection of LC, especially in LMIC - driven by multifactorial aspects, including a variety of socioeconomic and infrastructural factors, mainly due to limitations in the required network of specialized human resources and technical capacity. Identifying LC at an early stage allows for treatment that is more likely to be curative, thereby improving survival. The present study aims to characterize the lung nodule journey in different hospitals/clinics across Latin America, describing the use of health resources, time to diagnosis, stage at diagnosis, and time to treatment depending on the source of nodule identification in two different cohorts (retrospective and prospective).
A prospective, nonrandomized, open label study to evaluate the safety and IOP lowering effectiveness of the Streamline Surgical System, in patients with mild-to-moderate open angle glaucoma undergoing cataract surgery.
This study will evaluate the long-term sequelae of COVID-19 in patients diagnosed with COVID-19 who previously enrolled in a RO7496998 (AT-527) study (i.e. parent study), for approximately 6 months after the end of the parent study.
The purpose of this study is to analyze the effect of an interactive parent-child book reading intervention. The intervention includes two components: the provision of five children's books to parent-child dyads and information about how to practice interactive book reading. The investigators expect to find an effect of this intervention on a) infants' expressive vocabulary, b) reading activity, c) parental expectations and knowledge about language development and d) parental use of interactive book reading strategies.
Primary immunodeficiencies represent a underdiagnosed group of rare diseases which if diagnosed well and in time can be treated in an efficient manner and prevent complications that may affect the quality of patients life in an severe manner. Neither in Costa Rica nor in Central America studies or national registries regarding the prevalence and characterization of primary immunodeficiencies in adult patients exist up to now. This study reflects for the first time the epidemiologic situation of primary immunodeficiencies in a Central American country, characterizing adult patients diagnosed with primary and idiopathic immune disorders treated in two specialized immunodeficiency clinics in Costa Rica.
Determine the prevalence of homologous recombination repair (HRR) gene mutations in participants with mCRPC in Latin America (LatAm) between February 2021 and January 2022.
This is a Phase III, global, randomized, open-label, multicenter, study evaluating the efficacy and safety of adjuvant giredestrant compared with endocrine therapy of physician's choice in participants with medium- and high-risk Stage I-III histologically confirmed estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative early breast cancer.
The purpose of this study is to assess the efficacy and safety of pembrolizumab plus lenvatinib plus chemotherapy compared with pembrolizumab plus chemotherapy as first-line intervention in participants with metastatic esophageal carcinoma The primary hypotheses are that pembrolizumab plus lenvatinib plus chemotherapy is superior to pembrolizumab plus chemotherapy with respect to overall survival (OS) and progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR).
This study will evaluate the efficacy, safety, antiviral activity, and pharmacokinetics of study drug RO7496998 (AT-527) compared to placebo in non-hospitalized adult and adolescent participants with mild to moderate coronavirus disease 2019 (COVID-19) in the outpatient setting.
Passive immunotherapy is a therapeutic alternative used in a variety of infectious diseases including COVID-19. Equine polyclonal hyperimmune sera is a source of neutralizing antibodies against SARS-CoV-2 and a therapeutic alternative under investigation in COVID-19 patients. In the previous study NCT04610502 no significant variations were observed regarding efficacy and safety between two different pharmaceutical preparations of equine hyperimmune sera and adequate tolerability was reported with both investigational products. Formulations were produced through repeated immunization with viral recombinant proteins and contain either antibodies against SARS-CoV-2 S1 protein (S type) or a combination of viral proteins that included S1, N (nuclear), E (envelop) and M (membrane) (M type). Another investigation (NCT04494984) found that the administration of a pharmaceutical preparation similar to the S type produced clinical improvement in hospitalized patients with SARS-CoV-2 pneumonia, particularly those with severe disease. Aim: Evaluate the efficacy and safety of three different doses of an anti-SARS-CoV-2 hyperimmune equine serum formulation (S-type) as an addition to the standard therapeutic approach in adult hospitalized patients with a diagnosis of moderate or severe COVID-19, radiological findings consistent with pneumonia and a symptom onset period not exceeding 10 days. A total of 156 patients will be included and randomly divided into four groups, each group will receive a different dose of the investigational drug. On day 1, all participants will receive a single intravenous infusion containing the specified dose according to their assigned group. Clinical assessments, laboratory determinations that include: viral load, antibodies quantification, inflammatory and coagulation markers, cytokines levels as well as standard evaluations will be performed for each patient. Data will be collected for all groups on Days 0 to 7, 14 and 28 or at discharge after completion of treatment. The study will end for each participant on the day of discharge from the hospital.
