A 3.5 year-old Pompe disease subject (solid lines, diamonds) received weekly administration of 375 mg/m2 of rituximab along with 10 mg/kg of methylprednisolone for 3 weeks prior to dosing with 5 × 1012 vg/kg of rAAV1-CMV-hGAA. The patient then received daily oral administration of 0.06–1 mg/m2 of Sirolimus through the study and continued B-cell depletion with Rituximab every 12 weeks. Five Pompe subjects (dash-dot lines, circles), age 2.5–15 years, received 1–5 × 1012 vg/kg of rAAV1-CMV-GAA without immune modulation, served as a control group. The light horizontal lines represent +2 SD above the population mean. (a) Circulating antibodies against AAV1. (b) Circulating antibodies against hGAA. (c) Antigen specific response assay versus AAV1. (d) Antigen specific response assay versus hGAA.
