There are about 45 clinical studies being (or have been) conducted in Myanmar. 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.
Efficacy and safety of the artemisinin combination therapy (ACT) in uncomplicated falciparum malaria patients in Myanmar and artemisinin molecular markers analysis
Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems, including stomach cancer. Researchers want to look at samples of the bacteria. These H. pylori strains will be taken from chronically infected people. They want to identify the genetic and epigenetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get stomach cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer. Objectives: To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer. Eligibility: People ages 30-70 years who need an upper endoscopy or who were recently diagnosed with stomach cancer Design: Participants will be screened by the doctor who does their procedure and a study nurse. Participants who have endoscopy will have ~6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam. Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
In a randomized-controlled study, the effects of a structured, progressive, task-oriented home exercise program to optimize walking competency will be evaluated in subacute stroke survivors.
This study will investigate the use of misoprostol for first-line treatment of incomplete abortion at tertiary hospitals in Myanmar.
This study is an open-label randomised trial comparing standard ACT treatment with matching triple artemisinin-based combination therapies (TACTs), evaluating efficacy in safety and tolerability. The estimated total sample size is 2040 patients from 16 sites in Asia and 1 site in Africa. There are 2 arm study groups that have 2 treatment arms each. Study group A: A.1: Artemether-lumefantrine for 3 days. versus: A.2: Artemether-lumefantrine for 3 days plus Amodiaquine for 3 days. Study group B: B.1: Dihydroartemisinin-piperaquine for 3 days. versus: B.2: Dihydroartemisinin-piperaquine for 3 days plus Mefloquine hydrochloride for 3 days. Study group C: C.1: Artesunate-mefloquine for 3 days versus: C.2: Dihydroartemisinin-piperaquine for 3 days plus Mefloquine hydrochloride for 3 days. According to the WHO guideline, all patients except for children under the age of 1 year or a weight below 10 kilograms will also be treated with a single dose of low dose primaquine.
- Artemisinin resistance have been documented in Myanmar and Myanmar artemisinin resistance containment measures have been launched since 2009-2010. - It is important to monitor the spread and magnitude of artemisinin resistant malaria in Myanmar. - So, day-3 surveillance study have been conducted. - Recently artemisinin resistant molecular marker, K13 have been identified and it was used as a tool in this study.
This is a randomised two arm study, comparing artemether-lumefantrine 3 days and 5 days treatment. Patients will be randomised in blocks of ten to one of the two treatment arms. The standard regimen is twice daily for three days with a delay of at least eight hours between the first and second doses. A single of primaquine will be given to all patients on the first day of treatment for gametocytocidal activity. The initial treatment will be given under supervision, all other subsequent doses will be given to the patient to the taken at home. Patients will be followed up for nine visits over forty two days.
The overall aim of this study is two fold: 1. to pilot targeted chemo-elimination of plasmodium falciparum malaria in known areas of artemisinin resistance in South East Asia. 2. to understand the micro-epidemiology of malaria in these areas; chiefly, the prevalence and importance to on-going transmission of sub-clinical p.f malaria infections.
Complementary feeding diet in developing countries cannot meet iron requirements of infants and young children. Iron supplementation is mostly used to treat iron deficiency whereas iron fortification is cost-effective strategy to control iron deficiency in developing countries. However, a recent study showed that iron fortification imposed negative impact on gut microbiota by increasing colonization of gut pathogen over beneficial bacteria. Gut microbiota plays essential roles in nutrient absorption, vitamin synthesis; intestinal mucosal barrier function and pathogen displacement. Iron is essential for growth and virulence of most gut pathogens and so iron supplementation might have similar negative impact on gut microbiota composition. Therefore, nutrition interventions would not be justified by assessing micronutrient status alone ignoring any possible deterioration of gut microbiota. The investigators hypothesized that optimizing the nutrient intake from locally available foods according to complementary feeding recommendation (CFR) can improve the iron status of these children while maintaining healthy gut microbiota composition. A randomized, placebo-controlled, community-based, intervention trial will be conducted in Ayeyarwady division of Myanmar where childhood undernutrition is prevalent. The aim of this study is to compare the effect of optimized CFR to iron supplementation on iron status and gut microbiota composition of 1-2years old Myanmar children. Cluster randomization will be done at the village level to randomly allocate the villages into CFR or non-CFR villages. Individual randomization will be done to randomly assign each child into iron or placebo syrup so that individual children will receive one of 4 treatment groups (CFR, Fe, CFR + Fe, and Control) for a period of 24 weeks. Based on expected between-groups difference of hemoglobin 5g/L, at 80% power, 5% level of significance, 15% drop-out rate; after taking into account the cluster effect; required sample will be 109 per group (total = 436). A sub-sample of 15 children from each group will be randomly selected for gut microbiota assessment (total = 60). Blood samples for iron status and stool samples for gut microbiota assessment will be collected at baseline and endline. Anthropometric measurements, usual intake of iron and infectious disease morbidity will also be assessed.
Because the artemisinins are the most potent antimalarial drugs, the reduction in parasite numbers is rapid. Therefore, early measures of reducing parasite counts are needed. This study will look at conventional markers of parasite reduction e.g. parasite clearance time, parasite reduction ratio, and the time to achieve a fall of 50%, 90% and 99% of the pre-treatment parasitaemia. Defining artemisinin resistance requires the use of artesunate (AS) alone because it is now appreciated that the partner drug in a combination treatment has a significant impact on the rate of parasite clearance. This study will dose patients for 3 days with AS alone (or longer until parasites clear) and measure the parasite count frequently in order to be able to define an accurate regression line of a graph of the natural logarithm of the parasite count (Y axis) versus time (X axis). This will be followed by a full course of an artemisinin combination therapy (ACT). Two different dose regimens of artesunate will be compared at all sites except those in western Cambodia, as unpublished observations from the Thai-Myanmar border suggest the standard lower daily dose of 2mg/kg may enable the earlier detection of low level resistance than a 4mg/kg daily dose.
