Where did you get this new list ? I can't find it online. Very interesting to see Merck with a major position. That must be new. Interesting because IDRA and Merck had a partnership that began in '07 based around an earlier IDRA drug that was dissolved after safety issues halted a trial in 2011, I believe. Merck presumably is pretty knowledgeable about both Idera's science and their scientists. For them to come in and buy shares of Idera now is a very, very bullish sign.
Also glad to see Millennium significantly up their position.
