CHICAGO (Reuters) - An experimental Alzheimer's disease drug developed by Acumen Prescription tablets targeting a novel make of the toxic protein beta amyloid within the brain passed an early security check and must light reach to a bigger trial, the firm acknowledged on Sunday.
The drug, ACI193, used to be correctly tolerated within the main trial attempting out it in folks, the firm acknowledged. Results of the randomized, placebo-controlled gape of 62 sufferers with early Alzheimer's disease had been presented on the Alzheimer's Affiliation's Global Conference in Amsterdam.
Acumen's drug targets and binds to amyloid beta oligimers, a toxic, soluble version of the amyloid protein that kinds brain plaques associated with the memory-robbing disease, Dr. Eric Siemers, chief clinical officer of Acumen, acknowledged in an interview.
The target is solely like that of Biogen (NASDAQ:BIIB) and Eisai's only within the near past-licensed Leqembi, which hits one other soluble, toxic make of the protein within the brain. Leqembi obtained long-established U.S. approval earlier this month after showing it would possibly perchance take away amyloid plaques and dull the reach of Alzheimer's in early-stage sufferers.
Within the Acumen trial, 10.4% of handled participants (5 folks) developed a brain swelling condition identified as ARIA-E associated with amyloid-targeting treatments. Of these, most productive one had signs, which resolved after the drug used to be stopped.
Some other 8.3% developed bleeding within the brain associated with therapy, identified as ARIA-H.
"On memoir of this antibody targets oligimers nonetheless is now not intended to house plaque, we didn't know if we would bag any ARIA or now not," acknowledged Siemers, including that the ARIA instances also can suggest the drug is having an elevate out.
Of us that obtained higher doses of the drug also showed a reduction in amyloid plaque after 6 to 12 weeks, the firm acknowledged. Acumen acknowledged the gape suggests the drug can even be given as a month-to-month intravenous infusion.
