I am sure Hepalink and the other Chinese investors realize that the true value of RVX208 is in selling it in the US and other western countries where the insurance cos will pay a lot. So the logical owner of RVX is a company like Pfizer.
Anyway, if I remember correctly, Hepalink already owns the rights to market the drug in China.
I think Hepalink's balance sheet has to be a concern for their management. So they will gladly take cash.
