Considering what MRK paid for IDIX's nukes as well as what seems like a real interest by NVS in advancing ENTAs compound, I would like to think $1.5b would be the minimum someone would have to pay.
Why $1.5b? Why not 0.5B, $3B or $5B?
Remember that no Big Pharma will touch a product with a potential sale below $300M.
