Brief Summary:
It is an established fact that corona virus spread through the respiratory droplets Colonization of the virus in oropharynx andor 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-vivoThis 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 permissionConsent will be sought from the legal guardian in case of minor or underagedFormal 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 04 Group B and Group C will received 05 and 06 Group D will receive PVP-I nasal spray at concentration of 05 and Group E will received at 06 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-402 data analysis software
Detailed Description:
Rationale of the study
The coronavirus disease 2019 COVID-19 is a highly infectious disease and cause human to human transmission primarily by respiratory droplets from coughing sneezing and speaking In early SARS-CoV-2 infection a greater viral titre can be found in saliva and nasal mucous minimization of these titres should help to reduce cross infection Povidone-iodine PVP-I disinfectant has better anti-viral activity than other antiseptics and has already been proven to be an extremely effective virucide in vitro against severe acute respiratory syndrome and Middle East respiratory syndrome coronaviruses SARS-CoV and MERS-CoV Its in vivo virucidal activity is unknown though its nasal or oral preparation can be effective in reducing transmission Earlier a very few studies have evaluated the efficacy of povidone-iodine as nasal antiseptics or oral rinse antiseptics against the SARS-CoV-2 virus but the result of those studies are not undebatable So aim of this study is to investigate the virucidal activity of povidone iodine on coronavirus located on the mucosal surface of oropharynx and nasopharynx and is very rational in this pandemic period
Research Hypothesis
Objectives
General Objective
To determine the virucidal efficacy of povidone iodine on COVID-19 virus located in nasopharynx
Secondary objectives
i To determine the efficacy of povidone iodine to clear COVID-19 virus located in nasopharynx ii To assess the adverse events among the groups
Study Design Open label randomized clinical trial Place of Study Department of Otorhinolaryngology and Head Neck Surgery in collaboration with Department of Virology and Department of Medicine Dhaka Medical College Hospital Dhaka Bangladesh
Period of study The study period will be September 2020 to November 2020 Study population Confirmed cases of COVID-19 disease proven by RT-PCR testing Sampling and Statistical basis of the sample size The sample size is determined using the following formula Sample size estimated sample size 189 twenty seven in each group Research instruments General questionnaire for recording baseline information A checklist for for detecting COVID-19 status
Method and data collection
Participant selection and enrollment All patients admitted to the medical wards through emergency department or Outpatient department with suspected COVID-19 cases will be initially approached and screened for confirmation of the COVID-19 Confirmation of the COVID-19 will be done by positive impression of RT-PCR result Following confirmation of the viral infection the patients will be seen by the ward doctors and clinical trial physicians registered physicians Moreover baseline complete blood count CBC will be done for each patient Chest X-rayHigh resolution computed tomography HRCT will be done in necessary case The ward doctors and trial physicians will together care for the patient then the patients will be briefed about the aim objective and details of the procedure of the study If without capacity their relatives will be approached about the trial and seek their consent for recruitment As this study will be confined into a tertiary care hospital patients will be recruited up to day 4 of illness
Consenting participants It will be prioritized that the patients will be treated early for COVID-19 management by standard regiment and in accordance to the guidance of the national guidelines And within shortest possible time preferably within 4 hours of admission consenting procedure will be completed either from the patient or from the attendantlegal guardian of the patients to obtain the full potential benefit of the treatment Written informed consent will be obtained from the patient in their own language Bengali by trial physicians working on the trial
Screening for eligibility During admission demographic and clinical details including name agedate of birth gender duration of onset of fever and hospitalization vital statistics will be recorded before randomization RT PCR for COVID-19 will be used for confirmation of the COVID-19 virus infection A screening log will be maintained including these essential details and the decision taken by the patient or attendant or legal guardian where appropriate concerning recruitment Ineligible and non-recruited patients will also be cared by the ward physicians following standard treatment guidelines
Procedure of randomization The study participants will be randomly assigned in this study into six equal groups where each group has equal opportunity to receive any treatment option Randomization will be done by block randomization methods Randomization will be done quickly with baseline information typically captured in 15 min Recruitment randomization will be performed contemporaneously with assessmentresuscitation of patients by a second person so that medical care is not delayed by recruitment Patients will only be randomized once baseline data has been entered after this has been done participants will not be withdrawn from the study Following completion of the randomization the trial physicians reported the Principal Investigator PI of the trial and then the Principal Investigator PI handed over an opaque sealed envelope which will be numbered sequentially to correspond to patient enrollment numbers which will be used for concealment of treatment allocations Envelopes will be kept in a locked drawer and will be opened in strictly numerical order by in supervisor in presence of nursing supervisor of study unit Allocation between arms will initially be equal although this may be revised following guidance of the PI and his team as per the statistical plan
Withdrawal of study participants Participants are free to withdraw from the study at any point for any reason If this occurs the primary reason for withdrawal will be documented in the participants case record form The participant will have the option of withdrawal from
participant samples Randomized patients who wish to withdraw from the study before they have undertaken any study-related procedures will be replaced Data on the original participant will be kept on the CRFdatabase if the participant agrees to this
Investigational medicinal products
All of the Participants will be divided into three groups Group A will receive Povidone iodine PVP-I nasal irrigation NI at three different concentration of 04 Group B and Group C will received 05 and 06 Group D will receive PVP-I nasal spray NS at concentration of 05 and Group E will received at 06 concentration Group F Placebo comparator group will receive nasal irrigation by distilled water and Group G Placebo comparator group will received nasal spray by distilled water Participant compliance The study team will not create any problem with compliance while the patient is under care and supervision in hospital It was ensured that all recruited patients receive the appropriate interventions although it could be interrupted due to the onset of potential adverse effects such as hypotension
Responsibility sharing of care of the patients As the patients will remain under the care of the hospitals consultant physiciansunit head who will have primary responsibility for their management Management protocols will be agreed between the medical team and study team Decisions about intubation requirement of blood and blood products transfer of patients to intensive care weaning of ventilation and extubation will be made by the medical team independently of study doctors All decisions will be based on the patients clinical condition and the available hospital resources as per usual hospital practice The study team preferably by trial physicians will note down the record in patients Case Record Form CRF
Methods of data collection data collection will be done by the trial physicians A paper based semi-structured questionnaire was made and pre-tested before data collection All potential participants will be recorded in this database at first contact and assigned a study number This study number eg DMC-PVP-I-0001 will be used for all data and samples collected from that person Study doctors will recruit and randomize patients at the bedside with a randomization procedure They will not be able to predict allocation before randomization Following randomization allocation will be done by the PI and trial physicians or nurse will confirm the administration of the either drugdistilled water Patients will be closely monitored Temperature will be measured in every 6 hours blood pressure respiratory rate pulse rate will be measured in every hour Urine output will be measured in every 8 hours Drug related side effects or any adverse events will be observed in each group
If there is no reaction or unusual event another RT-PCR sample will be collected from the nasopharynx and sent for further testing
Total duration of the follow up will be for 2 days or person fulfills the discharge criteria All clinical events will be noted in case record form by trial physicians including vital status at hospital discharge Data entry will be datetime stamped Laboratory analysis data will be collected using same CRF
Data quality and standards following collection all data set and collected record form will be checked A formal clinical data management plan will be written before the study starts agreed by the co-investigators and Data Monitoring Committee and documented trail master file Laboratory results will be discussed regularly between the PI and laboratory managers
Proposed Analysis Plan of the study
Data analysis will be done by data management software R-402 Statistical significance is set as 95 confidence level at 5 acceptable error level Differences will be considered significant at the P 005 level for all these tests The data will be expressed as means Standard deviations SD for continuous variables and as frequencies for categorical variables Chi-square test student t test or ANOVA or other statistical test will be used in case of normally distributed data and similar non-parametric data will be used whenever appropriate Graph chart will be expressed by Microsoft Excel 2016
