There are about 373 clinical studies being (or have been) conducted in Guatemala. 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.
This study will examine the safety and efficacy of pembrolizumab (MK-3475) in combination with chemotherapy in children and young adults with newly diagnosed classical Hodgkin Lymphoma (cHL) who are slow early responders (SERs) to frontline chemotherapy.
The purpose of this study is to evaluate the efficacy of pembrolizumab (MK-3745) in the neoadjuvant (prior to surgery) or adjuvant (after surgery) treatment of previously untreated adults with gastric and gastroesophageal junction (GEJ) adenocarcinoma. The primary study hypotheses are that: - Neoadjuvant and adjuvant pembrolizumab plus chemotherapy, followed by adjuvant pembrolizumab is superior to neoadjuvant and adjuvant placebo plus chemotherapy, followed by adjuvant placebo in terms of Event-free Survival (EFS) based on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1), and - Neoadjuvant pembrolizumab plus chemotherapy is superior to neoadjuvant placebo plus chemotherapy in terms of rate of Pathological Complete Response (pathCR) at the time of surgery. With Amendment 10, upon study completion, participants will be discontinued and may be enrolled in an extension study.
The primary objective of this trial is to continue the provision of darunavir/ low-dose ritonavir (DRV/rtv) to adult and pediatric patients who previously received DRV/rtv in the clinical trials TMC114-C211, TMC114-C214, TMC114-TiDP31-C229 or in the pediatric trial TMC114-TiDP29-C232 who continue to benefit from the use of DRV/rtv, in countries where DRV is not commercially available for the subject, is not reimbursed, or cannot be accessed through another source (e.g., access program, governmental program).
This study is a randomized controlled trial of liquefied petroleum gas (LPG) stove and fuel distribution in 3,200 households in four countries (India, Guatemala, Peru, and Rwanda). Following a common protocol, each intervention site will recruit 800 pregnant women (aged 18-34 years, 9 - <20 weeks gestation), and will randomly assign half their households to receive LPG stoves and an 18-month supply of LPG. Control households are anticipated to continue to cook primarily with solid biomass fuels, and will receive compensation based on a uniform set of trial-wide principles, customized to each site based on formative research. The mother will be followed along with her child until the child is 1 year old. The researchers estimate that 15% of households will have a second, non-pregnant older adult woman (aged 40 to <80 years) who will also be enrolled at baseline and followed during the 18-month follow-up period. To optimize intervention use, the researchers will implement behavior change strategies informed by previous experiences and formative research in Year 1. This study will assess cookstove use, conduct repeated personal exposure assessments of household air pollution, and collect dried blood spots and urinary samples for biomarker analysis and biospecimen storage. The primary outcomes are low birth weight, severe pneumonia incidence, and stunting of the child, and blood pressure in the older adult woman. Secondary outcomes include preterm birth and development in the child, maternal blood pressure during pregnancy, and endothelial function, respiratory impairment, atherosclerosis, carcinogenic metabolites, and quality of life in the older adult woman. Participants in India, Guatemala and Rwanda will be followed until the child is 5 years old to assess the longer-term effects of the intervention.
The main purpose of the current study will be to provide real - world evidence regarding the safety and effectiveness of secukinumab in the management of patients with moderate to severe chronic plaque psoriasis.
This randomized, active controlled, multicenter phase III open-label study is designed to evaluate the efficacy and safety of alectinib compared with crizotinib treatment in participants with treatment-naive anaplastic lymphoma kinase-positive (ALK-positive) advanced non-small cell lung cancer (NSCLC). Participants will be randomized in a 1:1 ratio to receive either alectinib, 600 milligrams (mg) orally twice daily (BID), or crizotinib, 250 mg orally BID. Participants will receive treatment until disease progression, unacceptable toxicity, withdrawal of consent, or death. The study is expected to last approximately 144 months.
This 2-arm, randomized, open-label study will evaluate the efficacy and safety of trastuzumab emtansine versus trastuzumab as adjuvant therapy in patients with HER2-positive breast cancer who have residual tumor present in the breast or axillary lymph nodes following preoperative therapy. Eligible patients will be randomized to receive either trastuzumab emtansine 3.6 mg/kg or trastuzumab 6 mg/kg intravenously every 3 weeks for 14 cycles. Radiotherapy and/or hormone therapy will be given in addition if indicated.
This randomized, double-blind, placebo-controlled, two-arm study will assess the safety and efficacy of pertuzumab in addition to chemotherapy plus trastuzumab as adjuvant therapy in participants with operable HER2-positive primary breast cancer. This study will be carried out in collaboration with the Breast International Group (BIG).
This is a Phase III, multicenter, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of bevacizumab in combination with chemotherapy compared with chemotherapy alone in subjects with previously untreated metastatic breast cancer.
RATIONALE: Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known whether trastuzumab is effective in treating primary breast cancer in women who have completed adjuvant chemotherapy. PURPOSE: This randomized phase III trial is studying two different regimens of trastuzumab and observation only to compare how well they work in treating women with breast cancer.
