Avatar results will receive the go ahead nod from FDA
For Expanded Access yes, likely not approval until after Excellence. so no cruelty in the US with Expanded Access, nor elsewhere should various other country regulators allow similar compassionate access.
Your other quote: "I think the weakest link is the limited data for only 7 weeks on a chronic condition that does not have urgency as part of the problem."
Try telling that to the parents/caretakers of an adult with Rett syndrome. If the average age of death is 24 years old, then I would argue that time [urgency] is of the essence. (True, some live into their 40's and maybe a few can make it to their 50's with a lot of care...but those are the exceptional ones.)
Do you really think the FDA is going to dismiss the 7-year safety record just because it was based on elderly patients with AD?
And FWIW, Anavex does have a safety profile for Rett adults that goes back to 2019 from the original six adults that participated in the first Phase 2 trial. (See below)
"Preliminary Clinical Data is derived from the ANAVEX®2-73-RS-001 study on the first 6-patient cohort ranging in age from 18 to 36 years, who completed the pharmacokinetic (PK) part of the study and who received a low dose of approx. 5 mg daily oral liquid dose of ANAVEX®2-73 (blarcamesine) for 7 weeks. Patients are continuing participation in the ANAVEX®2-73-RS-001 open label extension study." https://investorshub.advfn.com/boards/read_msg.aspx?message_id=167772514
