There are about 317 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.
The main purpose of this study is to evaluate the antitumor activity and safety of Lenvatinib (MK-7902/E7080) in children, adolescents, and young adults with relapsed or refractory solid malignancies after administration. Participants will be enrolled into initial tumor-specific cohorts which will be expanded based on observed response.
Guatemala has enforced mandatory fortification of sugar with vitamin A (VA) since June 1974 and has led to a highly successful reduction in VA deficiency and associated disease. However, Ribaya-Mercado et al. 2014, estimated the biological impact of sugar fortified with retinyl palmitate that there may be a risk of chronic excess intake of preformed VA associated with programs of mass fortification. A recent food consumption survey in two departments in Guatemala found the average daily sugar intake in children under the age of two who aren´t being breastfed is 30.3 g, which translates into a daily intake of 272 μg of retinol (almost the full estimated average requirement (EAR) for that age group). Since data from the second National Survey on Micronutrients suggest a risk of VA toxicity, it is important to determine the levels of hepatic VA directly in corpses of individuals, of all ages, who have died of non-metabolic causes. Due to this, the investigators propose to assess liver and bone VA levels in combination with gene expression, histopathology and biochemical analyses, to elicit indications of hypervitaminosis A in Guatemala.
The purpose of this study is to determine the efficacy and safety of multiple CSJ117 doses (0.5; 1; 2; 4 and 8 mg) inhaled once daily compared with placebo, when added to standard-of-care (SoC) asthma therapy in adult patients with uncontrolled asthma with respect to change from baseline in FEV1 at the end of 12 weeks of treatment.
Since December 2019 the world has been shaken with an enormous global threat: the Covid-19 pandemic. This new kind of coronavirus is generating an unprecedented impact both on the general population and on the healthcare systems in most countries. Health services are trying to expand their capacity to respond to the pandemic, taking actions such as increasing the number of beds; acquiring necessary equipment to provide intensive therapy (ventilators), and calling retired health professionals and health students so they can assist the overwhelmed health care workforce. Unfortunately, these organizational changes at health facilities, along with the fears and concerns of becoming ill with the virus or infecting their families, put an enormous emotional burden on workers in health services which may lead to negative outcomes on mental health in this population. Recent cross-sectional studies in China indicate that health service workers exposed to people with Covid-19 reported higher rates of depressive and anxious symptoms. This negative impact on mental health among health workers in China has also been informally reported in other countries where the Covid-19 pandemic has been devastating in its effects (such as Spain and Italy), as well as in countries where the pandemic is becoming a growing public health problem. This is particularly relevant in regions with fewer resources (Latin America, North Africa), where there are limited means and the response from the health system is usually insufficient. Moreover, it is necessary to study these negative effects longitudinally considering that some effects will appear over time (post-traumatic stress). The COVID-19 HEalth caRe wOrkErS (HEROES) study is a large, bottom-up, South-North initiative aimed to evaluate the impact of the COVID-19 pandemic on the mental health of health care workers (HCWs). HEROES encompasses a wide variety of academic institutions in 19 LMICs and 8 HICs, in partnership with the Pan American Health Organization (PAHO) and with support from the World Health Organization (WHO). The HEROES study is led by Dr. Rubén Alvarado at University of Chile, and Dr. Ezra Susser and Franco Mascayano at Columbia U Mailman School of Public Health.
The specific aims of this study are: In a randomized controlled trial, the investigators will evaluate the impact of daily egg consumption during the complementary feeding period in addition to the local standard of nutrition care (i.e., intervention group), compared to the local standard of nutrition care alone (i.e., control group) on the following outcomes, in infants that are ~6-month old at baseline: 1. Child development, as measured by global development scores (primary outcome) 2. Growth, as measured by anthropometrics (secondary outcome) 3. Diet quality, as measured by the World Health Organization infant and young child feeding indicators (secondary outcome) Hypothesis: The investigators hypothesize that daily consumption of eggs during the complementary feeding period, in addition to the local standard of nutrition care, will improve child development, growth, and diet quality compared to the local standard of care alone.
70 couples (married or cohabiting) will be recruited across 5 countries (12-18 in each country: Argentina, Costa Rica, Guatemala, México, and Spain). After their entry into the study is confirmed, couples will be randomly allocated into one of two groups: intervention or control (no intervention). In each country, both groups will have equal number of couples. Couples in the intervention group will receive 20 sessions of Emotionally Focused couple Therapy (EFT). Couples in the control group will receive no intervention during the study period (they will receive a shorter intervention after the trial is over). Participants of both groups will fill questionnaires before allocation, during the intervention period and after the intervention period. The main outcomes will be couple attachment, couple satisfaction and dyadic adjustment. The study will start in February 2020 for Argentina and Guatemala, and in September 2020 for Costa Rica, México, and Spain. The study period for each couple will be around 6 months.
This study is designed to assess the antitumor efficacy and safety of pembrolizumab in combination with chemoradiotherapy (CRT) versus CRT alone in participants with muscle-invasive bladder cancer (MIBC). The primary hypothesis is that pembrolizumab + chemoradiotherapy is superior to placebo + chemoradiotherapy with respect to bladder intact event-free survival.
The purpose of this study is to evaluate the efficacy and safety of pembrolizumab plus concurrent chemoradiotherapy compared to placebo plus concurrent chemoradiotherapy in participants with locally advanced cervical cancer. The primary hypotheses are that pembrolizumab plus concurrent chemoradiotherapy is superior to placebo plus concurrent chemoradiotherapy with respect to progression-free survival and overall survival. Once the study objectives have been met or the study has ended, participants will be discontinued from this study and will be enrolled in an extension study to continue protocol-defined assessments and treatment.
The purpose of this extension study is to establish efficacy and safety of ligelizumab. This will be assessed in adult and adolescent chronic spontaneous urticaria (CSU) patients who have completed a preceding ligelizumab study and have relapsed, following treatment in these preceding studies, despite standard of care H1-antihistamine (H1-AH) treatment. In a subset of subjects, the safety and efficacy of ligelizumab monotherapy will be assessed. This study will also fulfill the Novartis commitment to provide post-trial access to patients who have completed studies CQGE031C2302, CGQE031C2303, CQGE031C2202 or CQGE031C1301
The purpose of this study is to assess the efficacy and safety of treatment with definitive chemoradiotherapy (dCRT) + pembrolizumab (MK-3475) compared to treatment with dCRT + placebo with respect to Overall Survival (OS) and Event-free survival (EFS) in: - participants with esophageal squamous cell carcinoma (ESCC), - participants whose tumors express Programmed Death-Ligand 1 (PD-L1) Combined Positive Score (CPS) ≥10, and - all participants. The primary study hypotheses are that dCRT+ pembrolizumab is better than dCRT + placebo with respect to: - OS in participants with ESCC, - OS in participants whose tumors express PD-L1 CPS ≥10, - OS in all participants, - EFS in participants with ESCC, - EFS in participants whose tumors express PD-L1 CPS ≥10, and - EFS in all participants.
