There are about 620 clinical studies being (or have been) conducted in Bangladesh. 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.
Folic acid is currently considered to be the standard of care for primary and secondary prevention of spina bifida, but the mechanisms underlying folic acid's benefits are unknown. One hypothesis is that folic acid changes DNA methylation and transcription of genes important in neural tube closure. In this study, the investigators will evaluate how DNA methylation of genes associated with neural tube closure changes after a short course of standard-of-care folic acid supplementation. In addition, the investigators will assess whether environmental arsenic exposure modifies the effects of folic acid on the methylosome.
This study is a Randomized, Double-Blind, Placebo-Controlled Trial. The objective of the study is to assess the effect of doxycycline in levodopa treated Parkinson's disease patients regarding motor performance and cognitive functions. Parkinson's disease patients on levodopa medications will be assigned to receive doxycycline 50mg twice daily or placebo over 8 weeks. The motor and cognitive symptoms of Parkinson's disease will be assessed after 4 weeks and 8 weeks follow up.
This is a double blinded, randomized-controlled, non-inferiority trial of a typhoid conjugate vaccine, Typhocon (Vi- polysaccharide conjugated to diphtheria toxoid, Vi-DT), manufactured by a local company, Incepta Vaccine Limited. The vaccine will be tested among individuals from 6 months to 60 years of age residing in Mirpur area of Dhaka city. The Typbar-TCV (Vi-polysaccharide conjugated to tetanus toxoid, Vi-TT), manufactured by Bharat Biotech International Limited will be used as a reference vaccine in this study. In Phase I the Typhocon vaccine will be tested in 30 adults. Safety and immunogenicity data of the vaccine for 30 adults will be submitted to the Data Safety Monitoring Board (DSMB), IRB and Directorate General of Drug Administration (DGDA). Upon receiving approval letter, the investigators will initiate the Phase II study including 600 individuals. The Phase II study will be conducted in age de-escalation manner (6-23 months, 2-5 years, 6-17 years and 18-60 years). Equal number of participants of all age groups will be enrolled for vaccination. Blood specimens will also be collected for carrying out the clinical chemistry (complete blood count with differential for white blood count, hemoglobin, absolute neutrophil count, platelet count, serum alanine transaminase, serum creatinine) on day -7 to day -2 for screening of participants before vaccination and on day 28, postvaccination. Based on blood reports of clinical chemistry, 600 participants will be randomized in a 1:1 ratio to allocate Typhocon or Typbar-TCV vaccine. Memory aid will be used to collect solicited adverse events following vaccination (AEFI) data up to day 7. Data on unsolicited AEFI and serious adverse events (SAEs) will be collected up to 28 days after vaccination. All study update including adverse events and serious adverse events will be reported to the DSMB. Blood specimen will be obtained on day 0 before vaccination, and day 28 for carrying out Enzyme-linked Immunosorbent Assay (ELISA) to determine anti-Vi-IgG antibody.
The investigational lotion is envisaged as an short- and long term "Ease & Prevent" monotherapy for adults and children with mild to moderate eczema. With itch representing the most burdensome symptom in eczema, the main objectives with the lotion is fast and efficient itch relief, high tolerability, and high short- and long term safety. This phase 1 study aims to monitor skin tolerability, and how much of the active compound that is absorbed to the bloodstream.
This is an open label and off label, phase IV, randomized clinical trial that will compare the immune response among infants that receive either two full doses of Sabin IPV intramuscularly or two fractional (1/5) dose of Sabin IPV intradermally at 14 weeks and 9 months of age from two different manufacturers.
It is well recognized that different patients respond in different ways to the same medication. These differences are often greater among members of a population than they are within the same person at different times (or between monozygotic twins). The existence of large population differences with small interpatient variability is consistent with inheritance as a determinant of drug response; it is estimated that genetics can account for 20 to 95 percent of variability in drug disposition and effects. Azithromycin is frequently used worldwide irrespective of gender or ethnic populations therefore, to investigate the impact of gender and ABCB1 gene polymorphism holds clinical significance. As a correlation between azithromycin high plasma level and cardiac arrhythmia also exists . If we can prove the variation of pharmacokinetics of azithromycin due to ethnic differences and ABCB1 polymorphism dose adjustment can be done. No relevant study regarding this has been done before in Bangladesh. Therefore, this preliminary study would be of great benefit to formulate the individualized doses regiment design which may improve the efficacy of drug while reducing adverse reaction. At the same time, Genotyping may prove an essential tool for individualized treatment by optimizing the drug dosage for an individual's genetic variability. Further study regarding pharmacogenetics of various drugs may be possible in our country in the future .The present study design to investigate the influence of ethnic difference and gene polymorphism on the pharmacokinetics of azithromycin in Bangladeshi Bangalee and Bangladeshi minor ethnic volunteers.
This study will be 8 weeks randomized, double-blind, placebo-controlled trail to assess the effect of astaxanthin in 80 moderate to severe knee osteoarthritis patients. Participants will be assessed at baseline and after 8 weeks of intervention. Subjects will be randomized to receive either astaxanthin 12 mg capsule daily or placebo capsule identical to astaxanthin daily for 8 weeks. Evaluation of pain, stiffness and improvement of physical function will be measured by WOMAC index before and after intervention. Inflammatory markers serum IL-6 and hsCRP will be measured before and after intervention. Astaxanthin related adverse events will be identified. Study outcome will establish safety and efficacy of astaxanthin in knee osteoarthritis.
The sodium found in salt is a powerful cause of high blood pressure, and most sodium ingested by humans is from their diet. High blood pressure is known to cause heart attacks and strokes, so various public health programs have attempted to find ways for people to reduce their salt intake to avoid these complications. These programs, however, have proven challenging, as asking people to alter their food preparation practices is often met with resistance. As such, we wish to test the blood pressure-lowering effects of low sodium salt substitute (LSSS), a salt substance in which a third of the compound by weight is composed of potassium (which does not increase blood pressure) rather than sodium. Additionally, the best way of supplying LSSS to people is yet unknown. We thus propose to study the effectiveness of an LSSS product by directly providing it via community health workers in 309 households in rural Bangladesh.
One million babies die, and at least 2 million survive with lifelong disabilities following neonatal encephalopathy (NE) in low and middle-income countries (LMICs), every year. Cooling therapy in the context of modern tertiary intensive care improves outcome after NE in high-income countries. However, the uptake and applicability of cooling therapy in LMICs is poor, due to the lack of intensive care and transport facilities to initiate and administer the treatment within the six-hours window after birth as well as the absence of safety and efficacy data on hypothermia for moderate or severe NE. Erythropoietin (Epo) is a promising neuroprotectant with both acute effects (anti-inflammatory, anti-excitotoxic, antioxidant, and antiapoptotic) and regenerative effects (neurogenesis, angiogenesis, and oligodendrogenesis),which are essential for the repair of injury and normal neurodevelopment when used as a mono therapy in pre-clinical models (i.e without adjunct hypothermia). The preclinical data on combined use of Eythropoeitin and hypothermia is less convincing as the mechanisms overlap. Thus, the HEAL (High dose erythropoietin for asphyxia and encephalopathy) trial, a large phase III clinical trial involving 500 babies with with encephalopathy reported that that Erythropoietin along with hypothermia is not beneficial. In contrast, the pooled data from 5 small randomized clinical trials (RCTs) (n=348 babies), suggests that Epo (without cooling therapy) reduce the risk of death or disability at 3 months or more after NE (Risk Ratio 0.62 (95% CI 0.40 to 0.98). Hence, a definitive trial (phase III) for rigorous evaluation of the safety and efficacy of Epo monotherapy in LMIC is now warranted.
