On Friday , the pharmaceutic company Biogenannouncedthe Food and Drug Administration take over its coating to conduct a precedence review of their experimental Alzheimer ’s drug for approving . The speedier - than - usual process set the stage for the intervention , hollo aducanumab , to be the first novel approved drug for the incurable , degenerative condition in virtually two decades . But there are many questions about whether aducanumab has enough evidence for its effectiveness .
Aducanumab is a lab - created antibody designed to target amyloid genus Beta , a protein establish in the Einstein . In those with Alzheimer ’s disease , muggy clumps of amyloid name memorial tablet form and amass in the mental capacity . Amyloid has long been thought to play a leading role in causing the brain damage that ’s characteristic of Alzheimer ’s , so many scientist had theorize that drugs capable of destroying brass could slow or forestall further destruction of the brain .
In March 2019 , however , Biogen and its Nipponese partner Eisai bothsuspendedtheir Phase III clinical trial of aducanumab , after an independent review encounter that the drug was improbable to meet the trials ’ primary destination of slowing down cognitive constipation in people trust to have mild Alzheimer ’s .

At the fourth dimension , aducanumab was take in as the latest failure for the once - anticipate line of anti - plaque drugs that had reached clinical trials . This lack of succeeder has started toconvince scientiststo look elsewhere for possible treatments , such as drug that interact with tau , another protein in the brain that forms into clumps call snarl in Alzheimer ’s patients .
In October 2019 , though , Biogenmadea surprising declaration . They had bet at their tribulation data ( including outcome pick up after the psychoanalysis that prompted the trial closure was complete ) and concluded there actually was data from the first trial showing that the drug would have meet the finish of perceptibly slowing down cognitive declivity in volunteers , compared to a placebo . The company also said it had hopeful information from a subset of patients in the 2nd trial run given a in high spirits acid of the drug , though the test overall still did n’t show a clinically significant result . With that , the company announced that it be after to submit the drug for review by the FDA .
This new development mean that the FDA will conduct a priority review of the drug for approval . The office will have to make a decision by March 7 , 2021 , though it may come down sooner than that . If the drug was approved , it would be the first Modern approved drug for Alzheimer ’s to come out in about 17 year , and likely the first destine to slow down or forbid the decline in quality of the shape . The fivecurrently approve treatmentsfor Alzheimer ’s only regale its symptoms .
Outside scientists and expert , however , have been questioning about the evidence for aducanumab , even afterthe ship’s company made some of its newer data useable last December . And some havewonderedout loud whether the company is simply spinning the information favorably to salvage a fail drug .
The next footstep of the process may provide some pellucidity to those interrogative . Before the FDA weigh in on an approval , it convenes a control panel of main expert in related fields to wait over the evidence themselves and make a testimonial . Though the recommendation are not tie , the FDA seldom differ with them . Time will soon tell whether aducanumab will hap muster there .
