If they wanted Millenium years ago, there is no way they let anyone else gobble this up... Just a matter of time, but the longer they wait, the multiple will just explode. I think SGEN fetches about 45 to 50 bucks...The technology is proven and the pipeline that grows out of the technology is a game changer in this space.
Yes a possibility but why pay the huge premium when they already share the benefits? I would like to see another drug covering a major disease platform. If and when that happens then we are off and running. Right now your estimate of $50 for a takeover seems reasonable IMO.
We keep talking about a buyout but the business model is taking shape and Adcetris is moving on more fronts. Collaborations, new drug developments and having money in the bank will allow SGEN to move up through the $30s and make long term investors very happy. Selling too early would likely be a mistake at this time.
