His press address at the White House last week placed immense significance on the development of a vaccine and if possible, new drugs to treat moderately severe cases of the disease. This week, the <a href=\"https:\/\/www.bloomberg.com\/graphics\/2020-coronavirus-cases-world-map\/\" target=\"_blank\" rel=\"noopener noreferrer\">number of deaths<\/a> neared 50,000 globally with Italy, Spain, and the United States recording 27000+ deaths. Needless to say, the need for more robust healthcare R&amp;D has never been higher. The murkiness in the current situation is multifactorial, as the importation of drugs from other countries including China was halted and the availability of ventilators diminishes.<\/p>\n<p>Amidst the lockdowns or industrial shutdowns to curtail the contagion, the academic community and healthcare researchers have been pulling in available resources together to meet the ever-rising demand for vaccines, medications, diagnostic kits, personal protective equipment, and other epidemic-fighting requirements. Here, I list some of the key developments that occurred in the past months to counteract the COVID-19 pandemic.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"COVID-19_research_Molecular_biology_pathogenesis\"><\/span>COVID-19 research: Molecular biology &amp; pathogenesis<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Since the upbeat chatter about the coronavirus emerged in December last year, the novel coronavirus (SARS-CoV-2) has been the epicenter of scientific <a href=\"https:\/\/www.kolabtree.com\/blog\/ensuring-reproducibility-in-ai-driven-research-how-freelance-experts-can-help-in-biotech-and-healthcare\/\">research<\/a> whilst wreaking havoc in more than 190 countries. Its origin was speculated to be <a href=\"https:\/\/www.nature.com\/articles\/s41586-020-2012-7\">from bats<\/a> and more recently, from a rare mammalian species <a href=\"https:\/\/www.nejm.org\/doi\/full\/10.1056\/NEJMc2005157\">called pangolins<\/a> in China. The pathogen causing COVID-19 is the seventh coronavirus that infected humans, after <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC7097181\/\" target=\"_blank\" rel=\"noopener noreferrer\">HCoV\u2010OC43, HCoV\u2010229E<\/a>, HCoV\u2010NL63, HCoV\u2010HKU1, MERS-CoV, and SARS-CoV, of which the first 4 are associated with mild respiratory distress\/infections while the last two have caused epidemics in <a href=\"https:\/\/www.nejm.org\/doi\/full\/10.1056\/NEJMoa1408636\">Middle-Eastern Asia<\/a> and Asia, Europe, <a href=\"https:\/\/www.cdc.gov\/sars\/about\/fs-sars.html\">North and South America in <\/a>the last decades, respectively. Characterized by an enveloped, positive\u2010sense, and single\u2010stranded RNA structure similar to all human-infecting coronaviruses, SARS-CoV-2 shares an almost similar lifecycle as SARS-CoV using the angiotensin-converting enzyme-2 (ACE2) receptor for entering human cells.<\/p>\n<p>The <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jmv.25766\" target=\"_blank\" rel=\"noopener noreferrer\">lifecycle of SARS-CoV-2<\/a> starts when the S protein is adjacent to the host cell\u2019s ACE2 receptor. This enveloped spike-like (S) protein represents the virus\u2019 most alarming, determinant feature that governs its pathogenicity; the S protein is composed of 2 domains S1 and S2 that enable the viral body to bind to the ACE2 receptor and fuse with the cell membrane. This S protein <a href=\"https:\/\/science.sciencemag.org\/content\/sci\/367\/6483\/1260.full.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">is densely glycosylated<\/a> and has a 10 to 20-fold higher affinity for the ACE2 receptor than SARS-CoV. The cell-membrane fusion between the host cell ACE2 receptor and S protein involves significant structural rearrangements to establish a stable post-fusion conformation, which is followed by viral RNA replication, transcription, and creation of a viral-protein rich genome. The viral proteins then enable the transmission of virions through the vesicles of the endoplasmic reticulum-Golgi complex (ERGIC).<\/p>\n<p>The mechanism of SARS-COV-2 transmission thus highlights the high-risk group primarily comprising <a href=\"https:\/\/academic.oup.com\/jtm\/advance-article\/doi\/10.1093\/jtm\/taaa041\/5809509\">cardiovascular disease patients<\/a> on ACE2 inhibitor and angiotensin receptor blocker (ARB) medications, because these medications mediate the creation of a large pool of ACE2 receptors in the circulatory frameworks. Another significant insight is that the S protein is being used as the target for potential vaccines, antibodies, monoclonal antibodies, and pharmaceutical treatments. Ongoing research aims to answer key questions regarding the variety of pathogenic strains of SARS-COV-2, its genetic similarities with other enveloped, single-stranded viruses, and the mutational abilities of its receptor-binding domains.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Preclinical_and_Clinical_Testing_of_Repurposed_Drugs\"><\/span>Preclinical and Clinical Testing of Repurposed Drugs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<blockquote><p>Currently, healthcare workers are utilizing crucial anti-malaria medications such as hydroxychloroquine and chloroquine to treat mild to moderate COVID-19 cases.

Here are some of the notable efforts with regard to novel coronavirus research and vaccine development:<\/p>\n<p>(a)\u00a0In the crowded race to develop <a href=\"https:\/\/www.sciencemag.org\/news\/2020\/03\/1-billion-bet-pharma-giant-and-us-government-team-all-out-coronavirus-vaccine-push\">immunizations against SARS-COV-2<\/a>, Johnson and Johnson is working on engineered adenovirus vector (Ad26 vector)-based vaccines, which have been preclinically tested and enter Phase I trials in September after selecting stable constructs of the vaccine. The company is focussing on the Adenovirus 26 vector because this is a nonreplicating viral vector that is absent in human genomes and can initiate the production of neutralizing antibodies. The company aims to start using the vaccine under the \u2018Emergency Use Application\u2019 regulatory clause, Paul Stoffels, J&amp;J\u2019s Chief Scientific Officer said.<\/p>\n<p>Similarly, in the United Kingdom, the <a href=\"http:\/\/www.ox.ac.uk\/news\/2020-03-27-oxford-covid-19-vaccine-programme-opens-clinical-trial-recruitment\">ChAdOx1 nCoV-19 vaccine<\/a> based on an adenovirus vaccine vector (ChAdOx1) developed at Oxford\u2019s Jenner Institute would be commencing clinical testing on patients with and without pre-existing conditions. The vaccine contains the genetic sequence of the S protein inside the ChAdOx1 construct and is expected to initiate adaptive immunity responses inside the susceptible patients. It was inspired by those developed previously for Middle East Respiratory Syndrome (MERS).<\/p>\n<p>(b) Significant progress was reported in April 2020 from the <strong>University of Pittsburgh School of Medicine<\/strong> regarding a <a href=\"https:\/\/doi.org\/10.1016\/j.ebiom.2020.102743\">vaccine candidate that initiated antibody development<\/a> in humanized mice models. The potential vaccine is a recombinant protein targeting the S protein delivered by microneedle arrays, which showed remarkable immunogenicity evident after a 14-day period. This research established the long-term immunogenicity of recombinant SARS-CoV-S1 and rSARSCoV-S1fRS09 immunogens. The <a href=\"https:\/\/www.thelancet.com\/journals\/ebiom\/article\/PIIS2352-3964(20)30118-3\/fulltext\">research<\/a> also emphasized the effectiveness of using microneedle array mediated immunization instead of traditional intramuscular or subcutaneous needle injections, in particular, the microneedle arrays deliver vaccine components to a defined 3D space within the skin microenvironment resulting in very high vaccine concentrations with relatively low dose antigen delivery.<\/p>\n<p>(c) The<strong> National Institute of Allergy and Infectious Diseases<\/strong> has <a href=\"https:\/\/clinicaltrials.gov\/ct2\/show\/NCT04283461\">started a phase I trial testing<\/a> mRNA-1273, an mRNA vaccine co-developed with Moderna Therapeutics. mRNA vaccines are considered high potency, rapidly producible, cost-effective, and safer alternatives to traditional live attenuated vaccines. Viral mRNA vaccines are limited by their delivery to infected cells. However, mRNA-1273 has been designed to be delivered by Lipid nanoparticle dispersion to inhibit the cell membrane fusion between the S protein and host cell ACE2 receptors. This phase I open-label trial I enrolling healthy adults with no reported pre-existing conditions.<\/p>\n<p>(d) <strong>Pfizer and BioNTech<\/strong>, a German company focussed on developing mRNA-based treatments, are working to develop a potential mRNA coronavirus vaccine. The vaccine candidate, BNT162, aims to prevent COVID-19 in patients by targeting the pathogen using either of the four mRNA formats developed by BioNTech based on uridine-containing mRNA, nucleoside modifications, and self-amplifying mRNA, which have the final goal of increasing the immunogenicity in the body. The companies are preparing to start clinical trials with the vaccine in April 2020.<\/p>\n<p>(e) Another <a href=\"https:\/\/www.reuters.com\/article\/us-health-coronavirus-singapore-vaccine\/singapore-scientists-study-genes-to-fast-track-coronavirus-vaccine-idUSKBN21B0P9\">academia-industry collaboration between<\/a> the <strong>Singapore-based Duke-NUS Medical School<\/strong> and <strong>US-based Arcturus Therapeutics<\/strong> focusses on the development of anti-SARS-CoV-2 mRNA vaccines based on its proprietary platform combining self-replicating RNA with nanoparticle non-viral delivery to initiate therapeutic protein production inside the human body. Preliminary test evidence that this self-replicating RNA-based therapeutic vaccine triggers rapid and prolonged immunity against infectious pathogens, which would be investigated for COVID-19.<\/p>\n<p>(f) The <a href=\"https:\/\/www.who.int\/blueprint\/priority-diseases\/key-action\/novel-coronavirus-landscape-ncov.pdf?ua=1\">World Health Organization reports that<\/a> 40+ vaccine candidates against SARS-COV-2 are under preclinical development and testing, comprising DNA vaccines based on nonreplicating viral vectors, DNA plasmid vaccines, recombinant peptides, inactivated viral vaccines, virus-like particles, receptor-binding protein-based proteins, and live attenuated vaccines that are under investigation at various academic institutions worldwide.<\/p>\n<blockquote>\n<h5><span class=\"ez-toc-section\" id=\"Experts_within_the_medical_research_and_healthcare_industry_have_forecast_that_it_will_not_be_earlier_than_January_2021_when_the_first_vaccine_candidates_are_available_for_clinical_application_Regarding_the_requirement_of_personal_protective_equipment_the_surging_demand_has_prompted_the_development_and_distribution_of_protective_masks_and_hospital-use_gowns_by_designer_apparel_band_Ralph_Lauren_and_American_footwear_brand_Under_Armour\"><\/span><em>Experts within the <a href=\"https:\/\/www.kolabtree.com\/industry\/medical-research\" target=\"_blank\" rel=\"noopener noreferrer\">medical research<\/a> and healthcare industry have forecast that it will not be earlier than January 2021 when the first vaccine candidates are available for clinical application.

The MDR was to take effect on May 26, which may be practically challenging considering the current burden on the healthcare facilities and medical device companies. <a href=\"https:\/\/ec.europa.eu\/commission\/presscorner\/detail\/en\/ip_20_589\">Stella Kyriakides<\/a>, Commissioner for Health and Food Safety, said in a statement: \u201cOur priority is to support Member States to address the coronavirus crisis and protect public health as powerfully as possible \u2013 by all means necessary. Any potential market disruptions regarding the availability of safe and essential medical devices must and will be avoided.\u201d The proposal also notes the complexity of MDR, adding that \u201cit is very likely that the Member States, health institutions, economic operators and other relevant parties will not be in a position to ensure the proper implementation and application of that Regulation from 26 May 2020 as it provides for.\u201d<\/p>\n<p>Meanwhile, the USFDA has approved the<a href=\"https:\/\/www.fda.gov\/media\/136622\/download\"> first serological test<\/a> developed by a North-Carolina based company under the \u2018Emergency Use Authorization\u2019 policy. The test can detect SARS-COV-2 antibodies, immunoglobulin M (IgM) and immunoglobulin G (IgG) that are generated as part of the human immune response to the virus. Although FDA recommends that serological test results should not be considered the sole basis to diagnose or exclude a coronavirus infection, the test can help in detecting the number of persons who have had SARS-COV-2, even if they did not show symptoms. Various companies await the authorization from the regulator of their potential COVID-19 diagnostic tests as the evidence of their unprecedented demand comes to the fore.<\/p>\n<blockquote><p><strong><em>The author wishes to honor healthcare workers working at the frontline of the pandemic.
