Bellerophon Starts INOpulse Treatment in Coronavirus Patients
Bellerophon Therapeutics has treated the first Covid-19 patient with its INOpulse at the University of Miami School of Medicine in the US.
This comes after the company received emergency expanded access from the U.S. Food and Drug Administration (FDA) for the inhaled nitric oxide system (iNO).
Clinical Trials Arena reports that NO is a naturally produced molecule that plays a key role in the immune response against pathogens and infections.
In-vitro studies found that NO blocks the replication of severe acute respiratory syndrome-related coronavirus (SARS-CoV) and improves the survival of infected cells. -

Japan's Fujifilm Starts Avigan Trial to Treat Coronavirus
Japan’s Fujifilm has begun clinical trials to test the effectiveness of its anti-flu drug Avigan in treating patients with the new coronavirus, after reports of promising results in China.
The Bangkok Times reports that trials in China have suggested Avigan (generic name: favipiravir) could play a role in shortening the recovery time for patients infected with coronavirus.
The drug will be administered for a maximum of 14 days to coronavirus patients between 20 and 74 years old with mild pneumonia, the spokesman said.
The study excludes pregnant women due to side effects shown in animal testing, he added. -

Pluristem Begins Dosing with Covid-19 Therapy in Israel
Pluristem Therapeutics has started dosing Covid-19 patients in Israel with PLX cells under a compassionate use programme approved by the country’s health ministry.
Dosing was performed in three patients at two hospitals. Pluristem intends to recruit more coronavirus patients in the coming days.
Clinical Trials reports that PLX cells are off-the-shelf allogeneic mesenchymal-like cells with immunomodulatory properties that could trigger the immune system’s natural regulatory T-cells and M2 macrophages.
This mechanism is expected to block the overactivation of the immune system, which leads to complications.
It is hoped that the approach will potentially decrease the incidence and\or severity of pneumonia and pneumonitis associated with Covid-19 infection. -

U.K. Considers Virus-Tracing App to Ease Lockdown
A coronavirus app which alerts people if they have recently been in contact with someone testing positive for the virus “could play a critical role” in limiting lockdowns, scientists advising the government have said.
The location-tracking tech would enable a week’s worth of manual detective work to be done in an instant, they say. The academics say no-one should be forced to enroll - at least initially.
U.K. health chiefs have confirmed they are exploring the idea.
The study by the team at the University of Oxford’s Big Data Institute and Nuffield Department of Medicine was published in the journal Science.
Leo Kelion writes for the BBC that the study proposes that an app would record people’s GPS location data as they move about their daily lives. This would be supplemented by users scanning QR (quick response) codes posted to public amenities in places where a GPS signal is inadequate, as well as Bluetooth signals.
If a person starts feeling ill, it is suggested they use the app to request a home test. And if it comes back positive for Covid-19, then an instant signal would be sent to everyone they had been in close contact with over recent days. -

Potential Drug Treatment Starts U.K. Trials
A drug that could help treat coronavirus is to be trialed on a small number of patients in England and Scotland.
The studies, which have been fast-tracked by the government, will initially involve 15 NHS centers.
The BBC reports that in the absence of a known treatment for the virus, a handful of experimental drugs are being tested globally.
The drug, known as remdesivir, is manufactured by the pharmaceutical company Gilead.
Two studies are to be carried out in the UK - one on patients with moderate symptoms, and one on those who are in a serious condition.
Trials are already underway in China and the US, with the first results expected in the coming weeks.
The UK trials will be based in England and Scotland and overseen by Dr. Andrew Ustianowski, a consultant in infectious diseases. -

An Experimental Peptide Could Block COVID-19
In hopes of developing a possible treatment for Covid-19, a team of MIT chemists has designed a drug candidate that they believe may block coronaviruses’ ability to enter human cells. The potential drug is a short protein fragment, or peptide, that mimics a protein found on the surface of human cells. Anne Trafton writes in MIT News that the researchers have shown that their new peptide can bind to the viral protein that coronaviruses use to enter human cells, potentially disarming it.
The MIT team reported its initial findings in a preprint posted on bioRxiv, an online preprint server, on March 20. They have sent samples of the peptide to collaborators who plan to carry out tests in human cells. -

Race against Time: The Complex Task of Developing a Vaccine against the New Coronavirus
University of Munich virologist Gerd Sutter talks about the complex task of developing a vaccine against the new coronavirus – and the approach he has adopted, which is already being tested against the related coronavirus MERS. According to the World Health Organization (WHO), more than 40 projects are already underway with the aim of producing a vaccine against SARS-CoV-2. Sutter’s comments: “Yes, a lot of things are now happening. Among them are projects which, like ours, are inspired by the protective effects of the MERS vaccine, but other vector-based approaches are also being tried. Then there is a whole series of projects that involve the use of nucleic acids, such as those being pursued by Moderna or by CureVac in Tübingen. At this point, it’s important to make use of all available technologies. If you asked me a year ago, I would have said that we would be very pleased if it took less than 2 to 3 years to get from the discovery of a new virus to a Phase-I trial of a new vaccine. Now, we can probably reckon with a year or thereabouts.”

In the Fight against Coronavirus, Antivirals Are as Important as a Vaccine
While many scientists are working on developing a coronavirus vaccine, others are busy testing antiviral drugs. Lisa Sedger writes in The Conversation that vaccines are generally only effective when administered prior to infection, but antiviral agents are important because they can treat people who already have COVID-19.
Sedgernotes that chloroquine, a well-known anti-malarial drug, has also gained attention. One study tested it together with a broad-spectrum antibiotic azithromycin. While some COVID-19 patients in this small study recovered, other patients died (despite chloroquine treatment), and some patients ceased treatment for a variety of reasons – including the severity of their symptoms.
“Nevertheless, people are interested in how chloroquine and azithromycin might work for coronavirus. Chloroquine exhibits antiviral activity and is currently used to treat autoimmune diseases because it also has anti-inflammatory properties,” she writes. “Azithromycin is an antibiotic used to treat bacterial infections, but it, too, exhibits antiviral activity, including against rhinovirus that causes the common cold. Chloroquine might need to be given early after infection to be most effective against coronavirus.” -

Century-Old Vaccine Investigated as a Weapon Against Coronavirus
A vaccine that’s been used to prevent tuberculosis is being given to health-care workers in Melbourne to see if it will protect them against the coronavirus. Jason Gale writes in Bloomberg that the bacillus Calmette-Guerin, or BCG, shot has been used widely for about 100 years, with a growing appreciation for its off-target benefits. Not only is it a common immunotherapy for early-stage bladder cancer, it also seems to train the body’s first line of immune defense to better fight infections.
The World Health Organization says it’s important to know whether the BCG vaccine can reduce disease in those infected with the coronavirus, and is encouraging international groups to collaborate with a study led by Nigel Curtis, head of infectious diseases research, at the Murdoch Children’s Research Institute in Melbourne. -

Uncertainty about Facts Can Be Reported Without Damaging Public Trust in News: Study
The numbers that drive headlines – those on Covid-19 infections, for example – contain significant levels of uncertainty: assumptions, limitations, extrapolations, and so on. Experts and journalists have long assumed that revealing the ‘noise’ inherent in data confuses audiences and undermines trust. A series of experiments – including one on the BBC News website – finds the use of numerical ranges in news reports helps us grasp the uncertainty of stats while maintaining trust in data and its sources.

FDA Authorizes 15-Minute Coronavirus Test
Federal health officials on Friday approved a coronavirus test that can provide results in less than 15 minutes, using the same technology that powers some rapid flu tests.
Arman Azad writes for, CNN that the U.S. Food and Drug Administration authorized the test for emergency use, signaling that federal regulators were satisfied with the test’s validation data and believe its benefits outweigh any risks, such as false positives or negatives.
The test’s maker, Abbott Laboratories, said it expects to deliver 50,000 tests per day beginning next week. The technology behind the test looks for genes that are present in the virus, similar to PCR (polymerase chain reaction) tests already on the market. -
