The huge move up in SAVA bodes well for AVXL eventually -- knowing as we do that AVXL's drug is targeting the same mechanism that SAVA is going after, but stopping the damage before it starts, instead of trying to fix it after the damage is done, like SAVA.

It would not surprise me to see both drugs prescribed for Alz patients -- AVXL's to halt further damage, SAVA's to help repair it.
