Earlier quoted context omitted.
Garbage In Garbage Out Open-Label studies on some poor country are not "quality evidence". (On the other hand I don't take that manufacturer's statement as a fair and honest assessment of the drug) We do need serious studies on the repurposing of drugs, but people take it as their silver bullet.
Garbage sure, as the many testimonies from doctors all around the world that say it works spectaculary. Big Pharma is running the show so no one is going to finance fancy double blind RCT´s. It´s completely crazy to ignore treatments for C19, this disease is easily treatable on symptom onset.
I have no view on this drug. But this standard of evidence is useless.
Every substance-disease pair has positive testimony from doctors around the world. Ground tiger bones for cancer? Paprika for polio? Leeches for fever? tons of testimony. Totally worthless. What you need are quality studies.
