$10 Billion Deal, page-7668

Is this why Biotron are looking at other compounds in their stable, to add to the possible drug to fight Covid19, one that not only has BIT225 in it but other compounds as well, i.e.BIT036, would a combination of these drugs be better than just one compound like BIT225 to fight Covis19 and HIV etc?
If so? then that may mean that they also have a better drug all round to kill HIV than Gilead appear to have now?
Biotron have to do this further testing IMHO to check for any variants so that another company doesn't produce a Chiral of a drug or combinations of Compounds that we invented to stop them getting the wood on us?
