Hi Cheri, there is definitely some evidence coming out that involves Enbrel use for RA with positive effects on depression, mild cognitive impairment, and other neurological disorders. I question why Amgen wouldn't release this drug for AD use, especially since it would be so profitable for them to do so. The only reason I can come up with is that the evidence isn't significant enough, or perhaps they are unsure of the other systemic effects this drug might have when administered intraspinally. When I spoke to Dr. Tobinick he said he is working on getting some national institutes to take part in the Enbrel study. If you check the government database for current clinical trials of this drug for AD you won't find any
http://clinicaltrials.gov/. Again, with the "evidence" that Dr. Tobinick has presented I question why more University/Medical research centers haven't taken this on.
