Background: In December 2019, SARS-CoV-2 was isolated on Vero E6 and Huh7 cell lines after an outbreak of pneumonia of unknown origin in Wuhan, Hubei Province, China. Since the basis for pathogenesis of this virus and its proliferation is unclear, there is still no definitive treatment or vaccine against it. Thus, medications used against SARS-CoV-2 are mainly based on their effectiveness on in vitro studies, virtual screenings and records of their effects on earlier strains of coronavirus, SARS and MERS. Therefore, the immediate introduction of potential COVID-19 treatments can be essential and salvaging. Aim: to compare the rate and time of viral clearance in subjects receiving the combination of Nitazoxanide, Ribavirin and Ivermectin vs. those control group (without any intervention). Methods: a sequential clinical trial in this design sample size is not fixed in advance. Instead data will be evaluated as they are collected, and further sampling is will be stopped in accordance with a pre-defined stopping rule as soon as significant results are observed. After "n" (10 subjects in each group) subjects in each group are available an interim analysis will be conducted. A statistical test will be performed to compare the two groups and if the null hypothesis is rejected the trial is terminated; otherwise, the trial continues, another n subjects per group will be recruited, and the statistical test is performed again, including all subjects. If the null is rejected, the trial is terminated, and otherwise it continues with periodic evaluations until a maximum number of interim analyses have been performed, at which point the last statistical test is conducted and the trial is discontinued [25]. Outcome: The combination of Nitazoxanide, Ribavirin, Ivermectin and Zinc could be effective in clearance of COVID 19.
KEY WOARD: COVID-19; clinical trial; corona virus
Full description
This search will focus on patients with COVID 19 infection this study is a prospective cohort study based on the analysis of response in comparative panel between two arm Nitazoxanide, Ribavirin and Ivermectin plus Zinc arm and other arm without any intervention as regards the safety and efficacy and cost effective result. Two years duration of the project would be enough to cover the stages of the work as shown below in the time plan. Initial stage of collecting materials and patients' clinical data, each patient will undergoes strict follow up period to reveal the clinical, laboratory and radiological response. The procedures are to be approved by the institutional ethical committee.
Study Design:
After obtaining informed consent from the subjects and IRB approval from Mansoura Faculty of Medicine.
Technical Design:
The proposed study will be hospital- based cross- sectional study.
Data collection tools and techniques:
1-Clinical work package: The aim of the Tropical Department in Mansoura University within WP1 is to implement surveillance, diagnostic and monitoring models for the disease management of patients with COVID 19 infection according to the current scientific evidence. They will evaluate the clinical usefulness of the application of therapeutic clinical trial, to improve the disease outcomes and reduce the costs of the disease burdens.
In brief, the approach will consist of the following steps:
Description of work and role of participants:
Rationale of study: COVID-19 is an emerging infection with relatively high transmission rate from healthy carriers to their contacts. There is no known drug that eliminate the virus from the nasopharynx.
Study objectives: to compare the rate and time of viral clearance in subjects receiving the combination of Nitazoxanide, Ribavirin and Ivermectin vs. those control group (without any intervention) Study hypothesis: The combination of Nitazoxanide, Ribavirin, Ivermectin plus zinc supplement have higher rate of viral clearance at earlier time than the control group
Population and methods:
A) Treatment group: will receive a combination of Nitazoxanide, Ribavirin and Ivermectin B) Control group: will not receive nothing
Data collection will include: sociodemographic data, clinical history, results of follow up (daily or according to clinical situation )
Follow-up: to record any side effects of drugs, swab will be taken for PCR
2-Laboratory and investigational work package:
The patients are subjected to following laboratory workup:
Task 2-1: basic laboratory serum analysis for the following parameters: transaminases (AST, ALT), albumin, bilirubin, prothrombin time, complete blood picture, renal assessment (creatinine or clearance if needed), CRP, Oxygen saturation
Task 2-2: specific laboratory analysis ( if available case by case ):
Serum samples from each patient are collected for analysis at different time for detection of ferritin, triglycerides, LDH,
3-Invetigational radiology work package:
This package includes chest x ray and /or high resolution CT
