This morning at the JP Morgan conference Celgene announced that they were buying Impact Biomedicines(private) for as much as $7 billion. This is a CVR type deal where Impact would get $1.1 billion up front, $1.4 billion of milestone payments and up to a maximum of $4.5 billion of sales milestones. This deal was done for a cast off cancer drug from Sanofi, fedratinib.
Yes these deals can happen long before phase III trials are complete.
