Chicagoest,
As far as I know, the only MOA that Resverlogix has disclosed for how RVX-208 may mitigate neurodegenerative diseases such as Alzheimer's is related to the ability of RVX-208 to elevate apoAI and HDL. However, there may be a lot more going on behind the scenes that would offer additional MOAs. So yes, it is possible that RVX-208 could improve the function of Verubecestat, but it's hard to guess not knowing more about how RVX-208 works in the brain. RVX does have a neurodegenerative clinical advisory board, and a substudy of BETonMACE is related to some memory/Alzheimer's readouts.....so clearly RVX is not giving up on Alzheimer's yet.
