According to the companies, the first report of rapid clinical recovery under emergency use of the drug was from Houston Methodist Hospital doctors.

The report said that a 54-year-old man who contracted Covid-19 while on treatment for rejection of a double lung transplant came off a ventilator within four days of treatment with RLF-100.
