Thanks for the link. I wonder though if you or anyone could opine on what this lady says starting at the 2:38 mark about too much autophagy actually causing or hastening cancer? TIA. Trying to learn.

This is what AI (Google) has to say about it:
The role of autophagy in cancer is complex and multifaceted. [1, 2, 3]
Protective Role: [4]
• Autophagy is a cellular recycling process that can help eliminate damaged proteins and organelles. In early stages of cancer development, autophagy can protect cells from accumulating harmful substances and prevent tumor formation. [5, 6, 7, 8, 9]
Pro-Tumorigenic Role: [10, 11]
• In established tumors, autophagy can promote cancer cell survival and growth. It provides nutrients and energy to cancer cells, helps them evade chemotherapy, and facilitates metastasis. [2, 3, 12]
Context-Dependent: [13, 14, 15]
• The role of autophagy in cancer depends on the specific context, including the type of cancer, stage of tumor development, and environmental factors. [9]
Evidence: [16]
• Studies have shown that autophagy can be both a tumor suppressor and a promoter in different cancer types. For example, autophagy is protective in colon cancer but pro-tumorigenic in breast cancer. [1, 8, 17, 18, 19]
Conclusion: [20]
Autophagy is a double-edged sword in cancer. It can play both protective and pro-tumorigenic roles depending on the context. Further research is needed to fully understand the mechanisms and implications of autophagy in cancer development and treatment. [1, 2, 3]

They are business days, Gary. The time to approval is directly related to benefit and safety issues. Big benefit, no safety issues...generally approval comes sooner. Very small benefit and significant safety issues push the time out and, of course., may lead to rejection. The US believes to a greater extent that the market should decide, while in the ROW regulatory bodies make an informed decision.

Thanks, I apparently didn't play much attention to it in that it proved to be so meaningless in NWBO's filing with the UK.
I do believe all the time they're taking is indicative of an approval, but specific terms are still under discussion.
I believe that investors are learning that a great deal of communications occur between the regulator and companies, but almost nothing either requires, or even permits acknowledgement by the company. From the time an admission is accepted/validated practically nothing is said about the status with the regulators that's official. At times investors who know people working trials, etc. may learn that they've been, or are being inspected, which is part of what's required to finish the evaluation. In reality, we really don't know when a poster was in some way a participant.

It's my understanding that the 210 days are the total days, not just business days, but I don't believe they start until the company is notified that their filing has been validated. I don't know if that's happened, or has ever been announced.
It's still meaningless as few filings are ended by the target date, but at least it's their goal. If as the company indicated this filing was something which was requested, perhaps the review will go rapidly and they'll actually meet, or even exceed their goal. Anything is possible, but don't hold your breath at day 210, you're likely to be very disappointed.

Actually, I got to know my mailman pretty well & he told me if he worked really fast they would extend his area of service, so he would from time to time, stop, pullover and read some of the magazines he was to deliver, then continue his hours at work!....or work a bit slower and get overtime! ha ha

The UK likes medicines that work, and, as you know, NWBO's candidate provides very questionable value. I think comparing NWBO's NIH application to AVXL's EMA application is not great. AVXL seems to have pretty incontrovertible evidence that 2-73 really works for AD - in the short term and the long term. You are right that we are lucky that the PDUFA date has been treated as binding by the FDA historically (although who knows now?) and EMA's dates are much more flexible. Still, 2-73 is solid dosage, no real SAEs, and data from related trials all have surfaced no other safety issues: maybe 2-73 will run the gauntlet faster than most?

This is a Lily ad for monoclonal antibody drugs to treat AD. Very well done I might add, but no mention of injection treatment mode, monitoring requirements, or likelihood of serious AEs (including sudden death).
Novel early detection methods like blood tests for amyloid, spinal taps, and MRI imaging are also mentioned, but no discussion of brain inflamation, disrupted cellular homeostasis, or impaired autophagy as root causes.
Dr. Sabaugh is convincingly effective when sharing about his father to demonstrate his commitment to this new approach to treating early AD.
I hope he is working on a follow-up video of similar quality for when AVXL gets the green light from EMA.
