Contrast Protalix's R&D efforts to Alexion which is hugely profitable and growing through expanded uses for its main drug Soliris.

Perhaps a larger company (Pfizer?) could do a better job unlocking the value there. --Written by Adam Feuerstein in Boston. >To contact the writer of this article, click here: Adam Feuerstein. >To follow the writer on Twitter, go to http://twitter.com/adamfeuerstein. >To submit a news tip, send an email to: firstname.lastname@example.org.
