Don't know what they are doing with their website, your guess as good as mine.
If they are going thru a buyout, what is the company that is buying them buying? Takeda already has the medication.
If they are bringing back the medication, they cannot release a SEC filing Thursday saying they have no clue if or when the medication will be brought back to market and then bring it back on the market a few days later.
Your guess is as good as mine as far as the recent increase in price and volume the past few days.
