A team of physician-scientists are now enrolling patients in a clinical trial to evaluate a common anti-clotting drug for the treatment of COVID-19-positive patients with ARDS. The newly launched trial follows a special report the team published that suggested the use of a drug called tPA could reduce deaths among patients with ARDS as a complication of COVID-19.

Prions are a class of misfolded proteins that form aggregates called "amyloid fibrils." These aggregates are the main culprit behind severe mammalian neurodegenerative diseases like Alzheimer's. What makes them so deadly is that they are capable of transmitting their erroneous conformation to otherwise healthy proteins, causing an imbalance in cellular function. Currently, there are no effective treatments for fatal prion diseases, mainly because studying mammalian prions is challenging.

No vaccines exist that protect people against infections by coronaviruses, including SARS-CoV-2, which causes COVID-19, or the ones that cause SARS and MERS. As COVID-19 continues to wreak havoc, many labs around the world have developed a laser-like focus on understanding the virus and finding the best strategy for stopping it. Researchers now suggest that the approach they took for a MERS virus vaccine may also work against SARS-CoV-2.

In the wake of the novel coronavirus pandemic, chemists have focused on searching for drugs to treat COVID-19. One group was identified the antiviral drug remdesivir as a viable medicine to treat COVID-19 in a research study published in late January. The drug was originally developed in response to the 2014 Ebola pandemic.
