Don't expect anything from Pfizer except fees, milestones for many years. Assume preclinical work is ongoing and do not expect more unless they are confident of approval. Yes they will need safety trials.
Halo was not mentioned in last few Q reports or at all this year that I recall. I was looking for verification that Pfizer was still interested in the platform. I want to see Pfizer in Phase II trials on anything and not just using the license as a blocker to competition.
