There are about 241 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.
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.
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.
This is a Phase III/IV, single-arm, multicenter study of the long-term safety and efficacy of atezolizumab treatment in participants with Stage IIIb or Stage IV NSCLC who have progressed after standard systemic chemotherapy (including if given in combination with anti-programmed cell death protein 1 [anti-PD-1] therapy, after anti-PD-1 as monotherapy, or after tyrosine kinase inhibitor [TKI] therapy). The study will consist of a Screening Period, a Treatment Period, a Treatment Discontinuation Visit, and a Follow-Up Period.
The purpose of this trial is to evaluate efficacy and safety of pembrolizumab plus standard of care (SOC) chemotherapy with cisplatin and 5-fluorouracil (5-FU) versus placebo plus SOC chemotherapy with cisplatin and 5-FU as first-line treatment in participants with locally advanced or metastatic esophageal carcinoma. The overall primary efficacy hypotheses are as follows: 1. In participants with esophageal squamous cell carcinoma (ESCC), participants whose tumors are programmed cell death-ligand 1 (PD-L1)-positive (defined as combined positive score [CPS] ≥10), ESCC participants whose tumors are PD-L1 positive (CPS ≥10), and in all participants, overall survival (OS) is superior with pembrolizumab plus SOC chemotherapy compared with placebo plus SOC chemotherapy. 2. In participants with ESCC, participants whose tumors are PD-L1 positive (CPS ≥10), and in all participants, progression-free survival (PFS) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by investigator is superior with pembrolizumab plus SOC chemotherapy compared with placebo plus SOC chemotherapy.
This was a multicenter, randomized study to evaluate the safety, immunogenicity, and efficacy of VRC-ZKADNA090-00-VP (Zika virus wildtype DNA vaccine) or placebo. In Part A, the primary objective was to evaluate the safety and tolerability of the vaccine in different vaccination regimens. In Part B, the primary objectives were to evaluate the safety and efficacy of the vaccine compared to placebo.
The purpose of this study is to assess the efficacy of voclosporin compared with placebo in achieving renal response after 52 weeks of therapy in subjects with active lupus nephritis.
A randomized withdrawal study in which responders to open-label treatment with tofacitinib will be randomized in a 1:1 ratio to tofacitinib or placebo in a double-blind phase. In the double-blind phase "time to sJIA flare" will be evaluated as primary endpoint and subjects will be discontinued once they experience sJIA flare. An interim analysis for efficacy and futility will be conducted when at least 20 flares have been observed. If either criterion is met, the study will be stopped. If neither criterion is met, the study will continue until the requisite number of flares are observed as determined by the number of flares included in the interim analysis and a statistical penalty for conducting the interim analysis.
The purpose of this study is to evaluate the clinical consistency of three production lots of the Porcine circovirus (PCV)-free liquid formulation of oral live attenuated human rotavirus (HRV) vaccine and to evaluate the PCV-free liquid formulation of HRV vaccine as compared to the currently licensed lyophilised formulation of the HRV vaccine in terms of immunogenicity, reactogenicity and safety when administered as a two-dose vaccination in healthy infants starting at age 6-12 weeks. No new subjects will be enrolled in the extension phase of the study.
This is a randomized, global, multicenter, open-label, Phase 3 clinical study in participants with severe hemophilia A without inhibitors against Factor VIII (FVIII) who are 12 years or older. The study evaluates two prophylactic emicizumab regimens versus no prophylaxis in this population with emphasis on efficacy, safety, and pharmacokinetics.
