GM1 Gangliosidosis Gene Therapy Study
Long-term Follow-up of RGX-121 in Mucopolysaccharidosis Type II (MPS II) Patients
This study will follow Mucopolysaccharidosis Type II (MPS II) patients after enrolling and receiving study drug RGX 121 in the parent study RGX 121-101. The purpose of this study is to determine drug safety and efficacy of RGX 121. No study drug is being given in this study.
If you agree to take part, your participation will last for up to 3 years after having completed participation in the parent studies. It will include up to 7 visits: up to 4 on-site study visits and 3 check-ins (e.g., over the phone or by internet). The impact of RGX-121 on biomarkers in patients' cerebrospinal fluid (CSF), blood plasma, and urine will also be evaluated in the long-term.
