It's a breakdown of just about everything, so too long to post outright, but here's our bit
TENTATIVE OR MIXED EVIDENCE EVIDENCE IN CELLS, ANIMALS AND HUMANS
Interferons
Interferons are molecules our cells naturally produce in response to viruses. They have profound effects on the immune system, rousing it to attack the invaders, while also reining it in to avoid damaging the body’s own tissues. Injecting synthetic interferons is now a standard treatment for a number of immune disorders. Rebif, for example, is prescribed for multiple sclerosis.
As part of its strategy to attack our bodies, the coronavirus appears to tamp down interferon. That finding has encouraged researchers to see whether a boost of interferon might help people weather Covid-19, particularly early in infection. Early studies, including experiments in cells and mice, have yielded encouraging results that have led to clinical trials.
On July 20, the British pharmaceutical company Synairgen announced that an inhaled form of interferon called SNG001 lowered the risk of severe Covid-19 in infected patients in a small clinical trial. They later published the details of the study in a medical journal, and in February SNG001 was given to participants in a large, ongoing clinical trial run by the National Institute of Health. On Oct. 20, Synairgen announced that the drug was advancing into a Phase 3 trial in mild to moderate COVID-19 patients.
Last August, the National Institute of Allergy and Infectious Diseases launched a Phase III trial on Rebif — the drug used for multiple sclerosis — combined with the antiviral remdesivir. The trial is completed, but the results have yet to be made public.
