Photo: UCHealth.<\/figcaption><\/figure>\n<p>REGN-COV2 contains two monoclonal antibodies, REGN10933 and REGN10987. These are lab-engineered proteins that act like the infection fighters your body produces after being exposed to SARS-CoV-2 or taking an effective vaccine that mimics aspects of the virus. Regeneron researchers evaluated thousands of antibodies produced by people who had recovered from COVID-19 as well as by mice genetically engineered to have human immune systems. They winnowed that long list down to those two antibodies. Both bind to different parts of the SARS-CoV-2 spike proteins the coronavirus uses to unlock human cells and ultimately hijack cellular machinery to make untold copies of themselves. So doing, in theory, gums up the ability of the virus to replicate.<\/p>\n<h3><strong>Regeneron results: So far, so good<\/strong><\/h3>\n<p>The preliminary results Regeneron announced on Sept. 29 applied to 275 patients of the 2,100 people expected to be involved in the outpatient study (six of them have been at UCH, Campbell says). That study is comparing viral loads among those who received one-time REGN-COV2 infusions of 2.4 grams, 8 grams, or a placebo. The company <a href=\"https:\/\/investor.regeneron.com\/news-releases\/news-release-details\/regenerons-regn-cov2-antibody-cocktail-reduced-viral-levels-and\" target=\"_blank\" rel=\"noopener noreferrer\">reported<\/a> that the drug sharply cut the amount of virus among those who got the drug; that patients with fewer natural coronavirus antibodies at the time they got the drug saw greater reductions in viral load than those with existing antibodies; and that the more virus a patient started with, the more impact the drug had in reducing viral load.<\/p>\n<p>Campbell called the results \u201cencouraging,\u201d but cautioned that Regeneron had yet to publish detailed, peer-reviewed data.<\/p>\n<p>\u201cWe don\u2019t know if those measures have any clinical significance, bottom line,\u201d he said. \u201cYou would think that they would, and you would think that they could correlate not only with getting people better faster by reducing the viral load in respiratory secretions but also that it would decrease the transmissibility \u2013 so reduce the infectiousness of the individual who has COVID and prevent spread to other people.\u201d<\/p>\n<figure id=\"attachment_34828\" aria-describedby=\"caption-attachment-34828\" style=\"width: 227px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-34828 size-full\" src=\"https:\/\/uchealth-wp-uploads.s3.amazonaws.com\/wp-content\/uploads\/sites\/6\/2020\/10\/05105152\/Dr.-Eric-Simoes.webp\" alt=\"Dr. Eric Simoes is working to understand whether drugs made by Regeneron help with COVID-19.

These efforts have gotten much less attention than those related to vaccine development (Campbell is <a href=\"https:\/\/www.uchealth.org\/today\/moderna-coronavirus-vaccine-trial-colorado-uchealth-university-of-colorado-hospital\/\">also leading<\/a> the Colorado trial site of Moderna\u2019s vaccine). But coronavirus-targeting antibody therapies, if successful, would represent major breakthroughs in taming the pandemic, particularly if they prove effective in bolstering patients\u2019 immune systems enough to keep what might have been serious cases out of hospitals and the most serious cases out of intensive-care units.<\/p>\n<p>Campbell\u2019s two studies have involved nine patients so far, he says.
