METHOD AND COMPOSITION FOR TREATING HUNTER SYNDROME THROUGH CEREBRAL LATERAL VENTRICLE ADMINISTRATION

摘要

A pharmaceutical composition including an iduronate-2-sulfatase beta (IDS-β) may be administered into the cerebral lateral ventricle once every four weeks to treat Hunter syndrome in a subject. Compared to a single administration of the same dose of an active substance, due to repeated administrations over a long period of time, the administration exhibits superior effects in treating Hunter syndrome, and further has the following effects which cannot be anticipated from the result of a single administration: treating or restoring a damaged brain structure; and substantially treating or improving brain functions, particularly, improving memory and learning.
