from the Japan Times:
A Japanese pharmaceutical firm will begin therapeutic testing of a drug it hopes will slow the decline in quality of life for some people with Down syndrome as they age.
The firm said Monday it will begin trial tests of its Aricept donepezil hydrochloride drug, commonly used to treat some of the symptoms of Alzheimer’s disease, on people between the ages of 15 and 39 who have Down syndrome.
Down syndrome is a congenital disorder frequently characterized by diminished mental faculty and physical abnormalities, including distinctive facial features.
It is caused by a chromosome defect and is proportionately more common in people born of older mothers.
From the midteens onward, roughly 6 percent of people with Down syndrome lose physical coordination, experience sleep disorders and become more withdrawn, a spokesman for drugmaker Eisai said.
“This testing, if effective, might show that the medication could improve their condition and help improve the quality of their lives,” the spokesman said.
It could also ease the burden on their caregivers, he added.
Some of the symptoms experienced by people with Down syndrome are common to some sufferers of Alzheimer’s, for which Aricept has long been prescribed.
The testing will initially involve 10 hospitals nationwide, with dozens of people in the affected age group.
The program will continue for up to four years, the spokesman said.
The drug is not intended to treat the underlying condition, he said, rather it is hoped it will target some of the symptoms.
Around 1 in every 830 newborns in the United States has Down syndrome, according to the National Institutes of Health. This equates to about 250,000 people in the country, it says.
