Both seem to be true -- Ariad people said not to think that they have other drugs, and they did publish about this choline kinase alpha molecule. I agree it's not really congruent. Bull case is that CHKA is a study compound that can be part of the pipeline. Base (and also bear) case is that CHKA has hurdles that are too high so they published the paper because that's all the payoff CHKA can give.
