About
Study 701-301 is a single-arm, open-label, switchover study in patients with late-onset Pompe disease who have been receiving treatment with recombinant human acid alpha-glucosidase (rhGAA) for 48 weeks or longer. Ambulatory patients who have mild to moderate respiratory impairment will switch directly to receive BMN 701 20 mg/kg by IV infusion every other week. All participants will receive active drug. No dose of existing therapy will be missed - experimental drug is started immediately.
