Effectiveness of Remedesvir in COVID-19 Patients Presenting at Mayo Hospital Lahore

Study Overview
=================
Brief Summary
-----------------
Currently, several drugs including Remdesivir, hydroxychloroquine, chloroquine, ritonavir+lopinavir, Tocilizumab, Arbidol and interferon are under randomised controlled trials (RCTs) for efficacy and/or safety evaluations in patients with COVID-19 in different countries. Remdesivir (GS-5734) is among these investigational drugs and some studies reported promising results. Remdesivir is a nucleotide analogue intravenous pro-drug developed by Gilead Sciences, an American biopharmaceutical company, for treatment of Ebola virus during the 2014 Ebola outbreak in Western Africa. Remdesivir shows broad-spectrum antiviral activity against many RNA viruses including SARS-CoV-2 through blocking RNA polymerase thereby terminating RNA transcription. Remdesivir was among the first treatments used in China as the outbreak emerges and it has been reported as potential treatment options for COVID-19 in the USA, China and Italy.

Detailed Description
-----------------
Coronavirus diseases 2019 (COVID-19) is caused by a novel β-coronavirus which is named as SARS-CoV-2. SARS-CoV-2 shares 79% RNA sequence identity with severe acute respiratory syndrome coronavirus 2 (SARS-COV2) and 50% genomic sequence identity with Middle East respiratory syndrome coronavirus (MERS-CoV) which caused a major outbreak since 2002 and 2012 in China and Saudi Arabia, respectively. Despite global containment measures to fight the disease, the pandemic continued to rise, rapidly spread across the world, and resulting in in 10.5 million confirmed cases and 51391 deaths worldwide as of July 1st 2020. The outbreak of COVID-19 infection has a significant threat to international health, the economy, psychological stress and mental health worldwide. Yet, there are no approved vaccines or drugs to make the disease less deadly; implying that searching therapeutic options are critical issues to overcome the outbreak. Studies are strongly underway to discover rapidly drug candidates for COVID-19, and studies are looking into repurposing drugs that have been used for the treatment of other diseases. Pakistan is badly facing this pandemic too. Up till now there are 221,896 confirmed cases with 4551 deaths with a death ratio of 2.1%. More than 3000 patients are critical.8 In Punjab, being allocated as a leading tertiary care centre for COVID-19 patients, Mayo hospital Lahore is dealing with each and every category of COVID-19 patients with variable presentations and treating those patients with different investigational drugs in keeping with other countries to find the best possible treatable drug. US Food and Drug Administration (FDA) has issued an emergency use authorisation (EUA) of the antiviral drug remdesivir for the treatment of patients with COVID-19. Although clinical trials have showed remdesivir as a treatment option for COVID-19, results are controversial. That's why we need to conduct a trial in our part of the world too to see its effectiveness in patients presenting with Covid-19. Remdesivir has been recently approved by CEAG (Corona Expert Advisory Group) for COVID patient is Mayo hospital. Remdesivir has never been used before in any public sector hospital in Punjab. Investigators aim to do this study in Mayo hospital Lahore to check the efficiency of this drug in COVID-19 patients in Mayo hospital Lahore OBJECTIVE: The objective of the study is to evaluate the effectiveness of remdesivir in patients with COVID-19 presenting to Mayo Hospital Lahore OUTCOME AND UTILIZATION: To date, no therapy has demonstrated efficacy for patients with COVID-19.This study will help in finding any definite role of Remdesivir in COVID -19 patients who are severely ill . Although data from several international ongoing randomized, controlled trials will soon provide more informative evidence regarding the safety and efficacy of remdesivir for COVID-19, but this needs to be evaluated in local arena too.
