I think another reference(analogy) using the discovery of penicillin might be useful to help. There was no accepted AAHHAAA penicillin moment b/c it's use on a wide variety of infections/bacteria was not part of the thinking at the time. Had medical science said at the time, "hey, lets try (fill in the blank) on N different kinds of infections and see what we get", then the whole process would have gone a faster path. But, no claims made and the dots did not get connected until years later.
That is not what is happening with A2-73(IMO). Dr. M. has claimed that A2-73 restores CNS cellular functions which should/will restore same across multiple (unstated) indications. If these 3 trials are used as evidence of validation for the process of CNS cellular restoration/regeneration in a generic sense then we get an AAAHHHHAAA moment.
