In 2008, Pfizer Drug Enbrel showed a 100% instantaneous improvement in Alzhiemer's dementia symptoms. Did Pfizer supress it? Important to clarify here that 100% improvement does not mean that they were 100 percent better.  But they were remarkably better (around 50% more functional- huge change  and it stopped the progression of the disease). Since 2006 there has been research that showed enbrel was effective and an effort to get further research done. In 2015 100;s of thousands of insurance records had been reviewed and showed that enbrel was preventing 60% of people from getting Alzheimer's. Still Pfizer sat on it for 3 more years and then decided not to pursue it further against their own  Researcher's suggestions.   https://www.msn.com/en-us/health/health-news/pfizer-had-clues-its-blockbuster-drug-could-prevent-alzheimers-why-didnt-it-tell-the-world/ar-AACoIHv?li=BBnb7Kz Pfizer sat on it for another 3 years and refused to study it further.  By then the Patent was almost up.  No money to be made. https://www.beingpatient.com/pfizer-coverup-enbrel-etanercept-alzheimers/ This starts similar to the MSN link but reports other research form 2006 found 15 patients with sustained improvement through Enbrel and other studies that pfizer chose to ignore.  This link reports why this drug works and the specific improvement in a 2008 follow up study to the 2006 15 person study. It advertises their attempt to set up a study but warns that hurdles to getting the study going could delay it.  It never happened. https://www.lifeextension.com/Magazine/2008/8/Novel-Drug-Therapy-Immediately-Reverses-Alzheimers-Cognitive-Deficits/Page-01 Big Question:  Why did the Washington Post break this story???? Is the CIA/Amazon now at war with Pfizer?  Is Amazon founder trying to remake his image?  Jumping ship and trying to gain goodwill?  And then why did MSN pick up the story and report it List price on Enbrel injections in 2008 was 675 dollars.  Injections need to be given weekly for 7 weeks. 2 year follow up showed no progression of the disease and gains were sustained. Pfizer made over 2 trillion off Enbrel and they claim it would have cost 80 million to fund the research to prove Enbrel treats Alzheimer's.
