Exactly right. The only unknown is time (when). AVXL-WW are involved in a discovery process which itself sets its own pace. We might sense that the curve of science unknowns is near some critical inflection point. This number of concurrent trials and the nature of precision science work might/should result in the kind of links which can finally put us all on the correct CNS path.
IMO, the simple agreement to our MOA thesis efficacy (based on trial findings) is evidence of world class science approval. Investors and regulatory bodies will/should part the seas after that.
