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.
Though OPV is safe and effective, it can mutate and reacquire neurovirulence in rare circumstances. This can result in vaccine-associated paralytic polio and circulating vaccine-derived polioviruses. Use of tOPV had risk of generating VAPP and seeding new type 2 circulating vaccine-derived polioviruses though wild type 2 virus was eradicated in September 2015. For this reason tOPV vaccine was withdrawn globally in April 2016 and switched to bOPV. cVDPV2 outbreaks have occurred in sixteen countries after cassation of OPV2. Using stockpiled mOPV2 to respond to this situation risks propagating new cVDPVs. IPV induces only limited intestinal mucosal immunity not effective to interrupt fecal-oral route transmission in settings of poor hygiene and sanitation. Therefore, development of novel oral polio vaccine with enhanced genetic stability and lower risk of reversion to neurovirulence compared to current Sabin 2 strains is major priority of global polio eradication Program Current clinical development plan outlines studies through Phase II development with nOPV2 candidate strains being tested in adult toddler and infant populations who received prior dose of OPV or IPV. No study has been conducted in truly naive newborns with no prior receipt of any polio vaccines Hypothesis: Vaccinating healthy newborns with novel type 2 polio virus candidate vaccines is safe and can induce putatively protective immune response Objectives Primary Objective Safety To evaluate the safety and tolerability after one and two doses of nOPV2 vaccine candidates 1 given 4 weeks apart in poliovirus vaccine-naïve newborn Immunogenicity To evaluate the immune response to vaccination after one and two doses of nOPV2 vaccine candidate 1 given 4 weeks apart in poliovirus vaccine-naïve newborns Secondary objectives Immunogenicity To evaluate seroprotection rate geometric mean and median titers to vaccination after one dose of nOPV2 vaccine candidate 1 in poliovirus vaccine-naïve newborns To further evaluate seroprotection rate geometric mean and median titers to vaccination after two doses of nOPV2 candidate 1 in poliovirus vaccine-naïve newborns Viral Shedding To assess trate of fecal viral shedding at fixed time points following one and two doses of nOPV2 vaccine candidate 1 in newborns To assess duration of fecal viral shedding at fixed time points following one and two doses of nOPV2 vaccine candidate 1 in newborns To assess extent of fecal viral at fixed time points following one and two doses of nOPV2 vaccine candidate 1 in newborns Exploratory objective To assess genetic stability through genetic deep sequencing assay and neurovirulence test through transgenic mice NV assays from a subset of participants stools samples
The aim of this study is to evaluate the preliminary safety and performance of a low-cost locally-made Venturi-based Non-invasive Positive Pressure Ventilator (NIPPV) device for hypoxemic COVID-19 patients. The device administers Continuous Positive Airway Pressure (CPAP) therapy using the jet-mixing or Venturi effect to increase the volume flow rate of oxygenated air from a pressurized cylinder by entraining the atmospheric air. To provide CPAP therapy, this high flow of oxygenated air is delivered to the patient via a low-cost non-vented mask with a tight seal with a High-Efficiency Particulate Air (HEPA) filter connected to the exhalation limb. The tight seal and HEPA filter ensures a minimal risk of aerosol generation and thus the device can be used without a negative pressure room. The system consists of the developed Venturi-based flow-generator, a standard 22mm breathing tube, a standard Y-connector, a non-vented CPAP mask (e.g., snorkel mask, helmet), a HEPA filter, and a Positive End Expiratory Pressure (PEEP) valve. The bench-top testing of the device is done in the laboratories of BUET and was verified that the device performs within the CPAP guidelines provided by the Medicines and Healthcare products Regulatory Agency (MHRA), UK. This study aims to assess the safety of and efficacy of the device in three different steps: (1) design validation, (2) clinical feasibility and (3) pilot clinical trial for safety and efficacy evaluation. Only if the device successfully passes the parts 1 and 2, the investigators will proceed to the final clinical trial in step 3. In this final step, the investigators aim to conduct a randomized controlled trial (RCT) evaluating for non-inferiority of the CPAP intervention compared to standard HFNO treatment. The number of ventilator-free days will be used as the primary outcome for efficacy, while patient recovery, death, or need of intubation and other adverse events will be used as secondary outcomes.
This randomized clinical trial was designed and intended to evaluate the efficacy of Remdesivir and Tocilizumab as a treatment for severe Acute Respiratory Distress Syndrome (ARDS) caused by Coronavirus disease 2019 (COVID-19). Our aim is to find the best option for the treatment and management of ARDS in COVID-19 patients.
Randomized double blinded clinical trial comparing amino acid based oral rehydration solution/medical food and glucose-based oral rehydration solution is infectious diarrhea in pediatric population
The primary goal of the village-level intervention is to assess whether mask-wearing reduces community-level COVID-19 seroconversion. The individual experiment assess whether masks protect against COVID-19 seroconversion. It also assesses the efficacy of high-quality cloth vs. surgical masks.
This is a randomized crossover study, where clinicians will be randomized to periods where they will use a rehydration calculator application with or without the Diarrheal Etiology Prediction (DEP) algorithm. The crossover will include a washout period to reduce carryover effect. The study will be conducted over a 9-week period. The Investigators will use a random number generator to randomize clinicians to DEP (use of the etiology calculator) or control arm (use of a previously-tested rehydration calculator) within site for the first 4 weeks. After the first 4 weeks, there will be 1-week washout period without decision support, after which each clinician will cross-over to the other arm for the next 4 weeks. The Investigators will enroll diarrhea-treating clinicians who treat children presenting with acute diarrhea at sites in Bangladesh and Mali. Utah investigators will only analyze de-identified data provided by our collaborators in Bangladesh and Mali.
Background - A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in December 2019 as the cause of a respiratory illness COVID-19 in Wuhan City, China. WHO declared a public health emergency outbreak of this virus on 30 January 2020 and declared COVID-19 a global pandemic on 11 March, 2020. Bangladesh reported its first case on March 8, 2020 and first fatality on April 1, 2020. Bangladesh had shown a staggered course of COVID-19 transmission initially but a surge in cases was observed from April, 2020. Remdesivir remains as the only potential therapy for the treatment of COVID-19 till date. Based on several pre-clinical studies in SARS-CoV and MERS-CoV infections, Animal trials in COVID-19 and data from human trials, this randomized, controlled, open label trial will evaluate the antiviral activity and safety of Remdesivir in Bangladeshi hospitalized patients with severe COVID-19. This study finding will provide knowledge if Remdesivir is effective enough to treat Bangladeshi COVID-19 hospitalized patients with adequate safety and tolerability. The result of this study will help the key opinion leaders regarding the matter, to take appropriate decision regarding usage of Remdesivir for the treatment of COVID-19 in Bangladesh. Study Procedure - All patients will receive the standard medical care for COVID-19+ve at the respective hospitals. Vital signs will be recorded every 24 hrs for 1st 5 days then once in 2 days till discharge or as per the discretion of the attending physicians. After screening the COVID-19 confirmed patients will be randomized into 2 treatment arms. Patient's safety assessment e. g. blood parameters (CBC, Creatinine, SGPT, RBS, Creatinine, Creatinine Clearance) will be done on screening, day 5 and day 14 or discharge; Chest X-ray and ECG on screening and day 14 or discharge. SARS-CoV-2 (viral load) will be looked in on day 5, day 10 and day 14 or at the time of discharge. In case any study patient deteriorates during the study period will be managed as per the guideline of that particular hospital and if needed will be shifted to ICU. Patients who will recover will be discharged as per the national guideline for the COVID-19 hospitalized patients. Patients will be contacted at 28 days either over phone or in person to get their health status since discharge.
This is an open-label randomized clinical trial that will compare immune responses among infants who receive either novel monovalent oral poliovirus vaccine type 2 (nOPV2) alone, bivalent oral poliovirus vaccine (bOPV) alone, or co-administered nOPV2 and bOPV.
It is an established fact that, corona virus spread through the respiratory droplets. Colonization of the virus in oropharynx and/or nasopharynx is considered to be major factor for transmissibility of the virus through respiratory secretions. Preventing colonization of the virus by administrating povidone iodine in the nasal passage therefore, a rational thought which is supported by recent evidence of in-vitro virucidal action of povidone iodine in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS CoV-2). Therefore, the study is designed to assess the virucidal effect of povidone iodine on COVID-19 virus in-vivo.This open label randomized clinical trial will be conducted at Department of Otorhinolaryngology and Head Neck Surgery, in collaboration with Department of Virology and Department of Medicine in Dhaka Medical College (DMC) Hospital. The study will be conducted from September 2020 to October 2020. Total 175 confirmed cases of COVID-19 disease, proven by Reverse transcription polymerase chain reaction (RT-PCR) testing will be enrolled in this study. Written informed consent will be ensured before participation. In case of no literacy, finger print will be considered for written permission.Consent will be sought from the legal guardian in case of minor or underaged.Formal ethical clearance will be taken from Ethical Review Committee (ERC) of Dhaka Medical College. All of the Participants will be divided into seven groups: Group A will receive Povidone iodine (PVP-I) nasal irrigation at concentration of 0.4%, Group B and Group C will received 0.5% and 0.6%; Group D will receive PVP-I nasal spray at concentration of 0.5% and Group E will received at 0.6% concentration. Group F (Placebo comparator group) will receive nasal irrigation by distilled water (DW) and Group G (Placebo comparator group) will received nasal spray by distilled water. The contact time will be minimum 30 seconds. After the individual application of PVP-I and distilled water in respective participant, they will be tested again for RT-PCR for COVID-19 from nasopharyngeal and oropharyngeal sample. All patients will be subjected to detail history, physical examination and adverse events. Block Randomization will be followed for randomization. Data will be recorded in a semi-structured questionnaire and will be analyzed by 'R-4.0.2' data analysis software
