Brief Summary:
This clinical trial expansion is to offer patients, who are not enrolled into the Phase I/II trial, a chance of treatment, to provide the experience in this gene therapy, and to increase the dose slightly.
Detailed Description:
AAV2-hAADC will be made by a GMP laboratory. An MRI will be performed to define the brain structure, and then metal nails will be fixed on the skull and a CT will be performed. The two images will be confined and the direction and depth of infusion will be determined. During the surgery, a stereotactic device will be implanted on both sides of the brain on a bur hole. Each putamen will be injected for two times. If there is no complication from the surgery, the patients will enter the follow up period.
In Cohort 1, subjects for high dose (2.37x10\^11 vg) will be enrolled via sequential enrollment with an observation for 2 months or even longer. Only after a subject passing peak dyskinesia, which is indicated by a reduced drug dose required for alleviation of dyskinesia, or improved food intake, and being verified by Safety Committee, treatment for the next patient with high dose can be proceeded.
In Cohort 2, in order to be compared with Phase I/II (n=10), 4 patients will be treated in Cohort 2 and all of them will use the high dose (2.37x10\^11 vg). Patients older than 3 (no more than 2 patients) years of age will be enrolled via sequential enrollment with an observation for 2 months or longer. Only after a subject passing peak dyskinesia, which is indicated by a reduced drug dose required for alleviation of dyskinesia, or improved food intake, which has been verified by the Safety Committee can the treatment at a high dose begin in the next patient older than 3.
