The drug, a combination of two antibodies called AZD7442, reduced the risk of severe COVID-19 or death by 50% in non-hospitalised patients who have had symptoms for seven days or less, the Anglo-Swedish drugmaker said on Monday. The risk reduction was even better in [patients who started therapy within just five days of initial symptoms](https://www.financedigest.com/covid-patients-showing-less-severe-symptoms-uk-vaccine-minister-says.html "COVID patients showing less severe symptoms, UK vaccine minister says"), but AstraZeneca joins an already crowded field of medicines that were shown to prevent deterioration in patients with mild disease when given soon after diagnosis. AstraZeneca executive Mene Pangalos said in a media call that the treatment results would mainly underscore the [potential future](https://www.financedigest.com/future-market-insightss-detailed-report-on-cat-litter-market-offers-projections-of-potential-impact-of-corona-virus-outbreak.html "Future Market Insights’s Detailed Report on Cat Litter Market Offers Projections of Potential Impact of Corona Virus Outbreak") use as a non-vaccine prevention.\[FWN2R716N\] “If and when this is approved it will be used in the treatment setting as well. But the real differentiator for this antibody is going to be in the prophylactic setting,” he said. Similar [therapies made with a class of drugs called monoclonal antibodies](https://www.financedigest.com/the-combination-antibody-therapy-market-to-grow-on-a-satisfactory-note.html "The Combination Antibody Therapy Market to grow on a satisfactory note") are being developed by Regeneron, Eli Lilly and GlaxoSmithKline with partner Vir. These [therapies are approved for emergency use in the United](https://www.financedigest.com/high-energy-shockwave-therapy-units-market-end-user-demand-by-types-regions-top-players-service-provides-regional-outlook-and-forecast-to-2028-2.html "High Energy Shockwave Therapy Units Market End-User Demand by Types, Regions, Top Players, Service Provides, Regional Outlook and Forecast to 2028") States for treating mild-to-moderate COVID-19. Regeneron’s therapy showed 72% protection against symptomatic infection in the first week, and 93% after that. GSK-Vir’s showed a 79% reduction in the [risk of hospitalisation or death](https://www.financedigest.com/risking-death-at-sea-rohingya-muslims-seek-safety-in-indonesia.html "Risking death at sea, Rohingya Muslims seek safety in Indonesia") due to any cause, while Eli Lilly’s therapy showed a 70% reduction in viral load at day seven compared to a placebo. Merck & Co Inc, in turn, is emphasising the convenience of use of its anti-COVID-19 tablet, which [cut the risk](https://www.financedigest.com/pfizer-says-antiviral-pill-cuts-risk-of-severe-covid-19-by-89.html "Pfizer says antiviral pill cuts risk of severe COVID-19 by 89%") of having to got to hospital or of dying by 50% in a trial of early-stage patients who had at least one risk factor. Merck, collaborating with Ridgeback Biotherapeutics, on Monday applied for U.S. emergency clearance for the oral drug. AstraZeneca, whose [COVID-19 vaccine](https://www.financedigest.com/eu-regulator-backs-novavax-shot-as-regions-fifth-covid-19-vaccine.html "EU regulator backs Novavax shot as region’s fifth COVID-19 vaccine") has been widely used across the globe, asked U.S. regulators last week to [grant emergency use authorisation](https://www.financedigest.com/token-granted-fca-authorisation-for-open-banking-payment-information-services.html "Token Granted FCA Authorisation for Open Banking Payment & Information Services") for AZD7442 as a preventative shot. As such, it is designed to protect people who do not have a strong [enough immune response to vaccines](https://www.financedigest.com/germanys-vaccine-panel-says-one-covid-shot-enough-for-children.html "Germany’s vaccine panel says one COVID shot enough for children"), primarily those who have received organ transplants or who are in cancer care. If [full market](https://www.financedigest.com/puma-confirms-full-year-outlook-flags-market-volatility.html "Puma confirms full-year outlook, flags market volatility") clearance is obtained after any emergency approval the market could widen, for instance, to include crew and passengers of a cruise ship, said Pangalos. You can [say the same for people who don’t want to be vaccinated but want an antibody,”](https://www.financedigest.com/jj-says-booster-dose-increased-antibodies-in-early-stage-studies.html "J&J says booster dose increased antibodies in early-stage studies") he added. AstraZeneca said it is submitting the new treatment [data on AZD7442 to global health regulators](https://www.financedigest.com/aon-introduces-new-cyber-solution-in-response-to-eu-regulation-on-data-protection.html "Aon introduces new cyber solution in response to EU regulation on data protection"). The trial took place across 13 countries and involved more than 900 adult participants, 90% of whom [suffered from conditions that made the particularly vulnerable to COVID-19](https://www.financedigest.com/soccer-manchester-united-suffer-covid-19-outbreak.html "Soccer-Manchester United suffer COVID-19 outbreak"), such as cancer and diabetes. One half receiving AZD7442 and the rest a placebo. Full trial results will be submitted for publication in a peer-reviewed journal, AstraZeneca said. AZD7442 contains laboratory-made antibodies designed to linger in the body for months to contain the virus in [case of an infection](https://www.financedigest.com/global-covid-19-cases-hit-250-million-eastern-europe-infections-at-record-levels.html "Global COVID-19 cases hit 250 million, eastern Europe infections at record levels"). A vaccine, in contrast, relies on an intact immune [system to develop targeted](https://www.financedigest.com/frances-dassault-systemes-shares-slump-on-reduced-licence-target.html "France’s Dassault Systemes shares slump on reduced licence target") antibodies and infection-fighting cells. While Monday’s results cover the use of AZD7442 in non-hospitalised patients, a separate trial is also studying its use as a [treatment for hospitalised COVID-19](https://www.financedigest.com/renal-cyst-treatment-market-covid-19-industry-analysis-future-trends-opportunity-growth-regional-outlook-and-forecast-2028.html "Renal Cyst Treatment Market COVID-19 Industry Analysis, Future Trends, Opportunity Growth, Regional Outlook and Forecast 2028") patients.
