As the Wuhan coronavirus relentlessly engulfs the world, scientists are relentlessly looking for a way to treat the infection. A vaccine is more than a year away, but an antiviral drug called remdesivir is being evaluated in clinical trials by Gilead Science, the world's premier antiviral drug company. Keep your fingers crossed. Although it is better to prevent an infection than treat one, sometimes drugs can be so effective in treating infections that the distinction becomes nebulous.

If so, Gilead, the world's premier antiviral pharmaceutical company, will have pulled off another miracle. Quite possibly. This is the beauty of automated cell-based assays. They can quickly test hundreds of thousands, even millions, of chemical compounds to see if any of them perform the desired result, in this case inhibiting the replication of the coronavirus, and if so, how well. But cell-based assays are only part of the process in drug discovery.

The lower the EC 50the more potent the drug. Its potency lies within the range of the three. Figure 1. The potency of four antiviral drugs in cell cultures.

But, the potency of a potential drug is only one parameter in a cell-based assay that must be considered. Cellular toxicity can be equally as important.

This is because viruses will only replicate in healthy host cells, so a compound that kills the host may also appear to be an antiviral, but it is just a cellular toxin. The higher the SI the more selective the drug. Figure 2. Dose-response curves of three drugs. The potency, toxicity, and selectivity of three potential coronavirus drugs tested by Wang et.

Its EC 50 0. Bioavailability is a measure of how well an orally administered drug gets into the bloodstream. The rest of the drug can either pass unchanged through the gastrointestinal tract and be excreted in the feces or get absorbed by the gut and be metabolized by the liver.The U. The trial, run by the University of Nebraska Medical Center along with the National Institute of Allergy and Infectious Diseases, will be conducted at up to 50 sites globally, and will test the medicine, called remdesivir, against placebo, according to the protocol.

At the time of the post on Friday, the trial was not yet recruiting patients. It's being tested in two trials in Wuhan, China, the epicenter of the outbreak, though Aylward noted slow enrollment in those studies because of declining patient numbers and trials of other medicines also being conducted.

Gilead's shares rose 4. A spokesman for the University of Nebraska Medical Center said he was unable to comment until information is publicly released. Gilead is among a dozen companies in the race to develop treatments, vaccines and diagnostic tests for the novel coronavirus.

Monday, biotech company Moderna said it had shipped the first batch of its potential vaccine to the NIAID to start human trials, sending its stock up 16 percent Tuesday. Remdesivir is an experimental antiviral drug that has shown some promise against other coronaviruses that cause SARS and MERS, but it hasn't been tested in humans with coronaviruses. It was tested in people with Ebola — which is caused by a different kind of virus — and was unsuccessful. The medicine was also used to treat the first U.

The patient appeared to improve the next day, but researchers note one patient's experience is not enough to determine whether the medicine works.

Oto treat the virus. A study published in the New England Journal of Medicine last week reported a coronavirus patient in the United States was found to show an improvement after taking Remdesivir, which is also used to treat infectious diseases such as Ebola.

Gilead did not immediately respond to request for comment but last week said it was working with China to test Remdesivir for use in a small number of patients with the coronavirus. The Wuhan-based laboratory said in its statement that the patent application was filed on Jan.

However, it said it would temporarily drop its patent claims if the opportunity arose to collaborate with foreign pharmaceutical firms to fight the epidemic. Discover Thomson Reuters. Directory of sites. United States. World News. Zhang YanDavid Stanway.These randomized, open-label, multicenter studies will enroll approximately 1, patients at medical centers primarily across Asian countries, as well as other countries globally with high numbers of diagnosed cases, beginning in March.

The studies will assess two dosing durations of remdesivir, administered intravenously. The initiation of these studies follows the U. Gilead has donated drug and provided scientific input for these studies, with results from those in China expected in April.

The Gilead studies will evaluate two dosing durations of remdesivir. One study will randomize approximately patients with severe clinical manifestations of COVID to receive either five or 10 days of remdesivir.

The second study will randomize approximately patients with moderate clinical manifestations of disease to receive five or 10 days of remdesivir or standard of care alone. The primary endpoint of both studies is clinical improvement, as described below. Remdesivir is not yet licensed or approved anywhere globally and has not been demonstrated to be safe or effective for any use. Working with government agencies, non-governmental organizations and local regulatory authorities, Gilead is providing remdesivir to qualified patients with COVID on a compassionate use basis for emergency treatment outside of ongoing clinical studies.

Remdesivir is an investigational nucleotide analog with broad-spectrum antiviral activity both in vitro and in vivo in animal models against multiple emerging viral pathogens including Ebola, Marburg, MERS and SARS. Remdesivir has been studied in healthy volunteers and in people with Ebola virus infection.

Individual compassionate use cases are not sufficient to determine the safety and efficacy of remdesivir in treating COVID, which can only be determined through prospective clinical trials.

The first of two studies will evaluate the safety and efficacy of both a 5-day and a day dosing regimen of remdesivir administered intravenously in patients with severe manifestations of COVID Approximately participants will be randomized in a ratio to receive remdesivir mg on day one, followed by remdesivir mg each day until day 5 or 10, in addition to standard of care.

The second study will evaluate the safety and efficacy of a 5-day and a day dosing regimen of remdesivir administered intravenously in patients with moderate manifestations of COVID, compared with standard of care.

Approximately participants will be randomized in a ratio to receive remdesivir mg on day one, followed by remdesivir mg in addition to standard of care each day until day 5 or 10, compared with standard of care alone.

But RBC Capital Markets analysts examined individual patient data and decided the Gilead drug showed mixed results, at best. The analysts also noted that remdesivir patients experienced nausea, vomiting, rectal bleeding, and elevated liver enzymes. As the pandemic spreads, a race is underway to develop therapies and vaccines, but also cull existing treatments for ways to combat the virus.

The Gilead drug, which was revived recently, is high on the list and testing has begun in the U. The drug maker, which distributed the drug on a compassionate use basis to several hundred patients, expects to start its own late-stage trials this month. Consequently, every twist and turn involving each product and each test will be closely scrutinized for signs of effectiveness. Even preliminary findings will be picked through for clues, given that countless lives depend on such outcomes.

Moreover, the Gilead drug was typically given to patients as they worsened, so it remains possible the drug prevented them from taking an even worse turn. Finally, the analysts noted that remdesivir was given to the patients at a later stage of illness than in the clinical trials, suggesting the therapy can yield a better outcome if administered sooner rather than later.

Transient low-grade elevations in liver transaminases were observed during the Phase 1 studies in some participants — the clinical significance of these laboratory changes is not known. In these studies, no significant adverse events or laboratory abnormalities were attributed to remdesivir by study investigators.
