I don't think 5.4c is so much of a joke. The company isn't making any money at the moment. That's OK; it's a speccy, but in order to make anything other than a few hundred thou here or there one of these pharmas has to actually produce something useful from the library. PYC can't control this. Roche looks like it might be going down that path (albeit very opaquely), but the library can only get the drug across the blood-brain barrier; it doesn't control how effective it is when it arrives there.

So, 54c if Roche works out, 5.4 in the meantime.
