ALZHEIMERS NEWS-IT DIDNT WORK
amyloid begins to accumulate in the brain forming plaques years before symptoms start
the amyloid plaques causes brain cell destruction in the brain
next
tau proteins accumulate in the brain as tau tangles causing more brain cell death
next
the body sends in its inflammatory army which kills more brain cells
it was felt that if you could remove the amyloid from accumulating you could stop or slow down the alzheimers disease process in the brain
antiamyloid antibodies called monoclonal antibodies were developed
solanezumab was one of the first
later came my drug aduhelm or aducanumab and now we have leqembi or lecanemab
soon to be approved is the newest one donanemab
each one seems to work better than the previous one
solanezumab approached the amyloid plaques differently
as the final report shows it was not good enough
when i read the final report it didnt work better than placebo
lucky for us in the alzheimers world the newer ones do work in removing amyloid plaque and slowing memory decline
i recently read an old blog i wrote about 8 years ago about trying to get in the solanezumab studies
one study was treating folks with moderate alzheimers
i wasnt far enough along to qualify for that one
that study was not effective in slowing down the disease
the second study
the a4 study
antiamyloid treatment in asymptomatic alzheimers
to get in this study
you had to have amyloid plaques in the brain
ie a positive amyloid pet scan or positive amyloid levels in the spinal fluid
you had to have normal memory on memory testing
that would mean you are prealzheimers or prodromal alzheimers
i tried to get into the study but was turned down even though my memory was back to normal on testing
it was those initial scores those first two years that kept me from being in that a4 study
as it turns out for me im glad i didnt get in the study since i later got into the aduhelm or aducanumab study that i am in now
in the a4 study solanezumab didnt work
amyloid pet scans showed no change in the amyloid pet scans in either the treated group or placebo
memory continued to decline in both groups
these three other ones i mentioned above do remove all the measurable amyloid from the brain
most within 12 months
these three other ones also show a slowing of memory decline
these three others ones are approved for use in early alzheimers and mci or will be soon
these three other ones are doing their own long term studies in folks who are prealzheimers
ie positive amyloid pet scans with normal memory
i expect these three other ones to show that treating people before symptoms start will be successful
for me
when i was say 50 had i known then what i know now and this was available
i would had asked to be in these prealzheimers studies
i would have been getting monthly infusions while in my last 10 years of practice
and
if it worked i would not have had to quit practicing medicine at 60
then
i would die at an old age but it wouldnt be from alzheimers
thats what we are looking at if these newer antiamyloid drugs work
i think about the folks who were in the a4 study
some got placebo some got the real drug
it didnt work
they had all hopes for over 5 years some a lot longer
then
to find out
solanezumab just didnt work
at all
how devastating that must be
i remember how i felt after about 18 months our study was abruptly stopped
i felt like i had been kicked hard in stomach
im sure thats how the a4 study subjects felt
they lost ground on their disease that they will never get back
in medicine sometimes you have to have a lot of failures before you have success
next tuesday i get my #28 infusion of aduhelm or aducanumab at ucla
my amyloid pet scan is in about 6 weeks
it should read out clear of amyloid plaques
oh how i would love to see that scan

Th anks for the report
