There are about 244 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 purpose of this clinical study is to evaluate the surgical, refractive, and visual outcomes with implantation of an investigational intraocular lens (IOL).
This study is to evaluate the safety and efficacy of pembrolizumab/vibostolimab (MK-7684A) in combination with concurrent chemoradiotherapy (cCRT) followed by pembrolizumab/vibostolimab versus cCRT followed by durvalumab in participants with unresectable, locally advanced, stage III Non-small Cell Lung Cancer (NSCLC). The primary hypotheses are that pembrolizumab/vibostolimab with cCRT followed by pembrolizumab/vibostolimab is superior to cCRT followed by durvalumab with respect to the following: - progression free survival (PFS) per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 by blinded independent central review (BICR) in participants with programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) ≥1% and PD-L1 all comer participants. - overall survival (OS) in participants with PD-L1 TPS ≥1% and PD-L1 all comer participants.
A study of the Streamline Surgical System versus competitor
This study will evaluate the efficacy and safety of multiple therapies in participants with locally advanced, unresectable, Stage III NSCLC with eligible biomarker status as determined by Version 8 of the American Joint Committee on Cancer/Union for International Cancer Control NSCLC staging system.
This is an open-label, multi-center, roll-over study to evaluate the long term safety of ribociclib in combination with other drugs in participants who are participating in a Novartis sponsored global study, that has fulfilled requirements for its primary objective(s), and who in the opinion of the Investigator, would benefit from continued treatment.
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. In addition, an open-label exploratory substudy will explore the safety and efficacy of giredestrant in combination with abemaciclib in a subset of the primary study population.
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).
The purpose of this study is to assess the efficacy and safety of co-formulated pembrolizumab/quavonlimab versus other treatments in participants with MSI-H or dMMR Metastatic Stage IV Colorectal Cancer.
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.
This is a clinical trial comparing an investigative accommodative IOL and two commercial IOLs in patients with cataracts undergoing primary cataract surgery.
