The design and endpoints used in cancer studies -- overall survival, progression-free survival, response rates -- are common and well understood, so an SPA probably doesn't add anything. (Although some cancer drug companies still seek them out.)
But if a company is developing a drug for a disease for which there are no approved drugs, or wants to use a novel endpoint, an SPA is definitely a good thing and something I look for when doing my research.
My column naming Genzyme's Henri Termeer the Worst Biotech CEO of 2009 barely generated a peep on the controversy meter. Nearly all of the email and comments I received were from people who agreed with me. Kinda strange.Steve P. writes, " Oy Vey!

Roger W. also agrees: " Thanks for having the
