Long-term follow-up of endurance and safety outcomes during enzyme replacement therapy for mucopolysaccharidosis VI: Final results of three clinical studies of recombinant human N-acetylgalactosamine 4-sulfatase
چکیده انگلیسی

The objective of this study was to evaluate the long-term clinical benefits and safety of recombinant human arylsulfatase B (rhASB) treatment of mucopolysaccharidosis type VI (MPS VI: Maroteaux-Lamy syndrome), a lysosomal storage disease. Fifty-six patients derived from 3 clinical studies were followed in open-label extension studies for a total period of 97–260 Weeks. All patients received weekly infusions of rhASB at 1 mg/kg. Efficacy was evaluated by (1) distance walked in a 12-minute walk test (12MWT) or 6-minute walk test (6MWT), (2) stairs climbed in the 3-minute stair climb (3MSC), and (3) reduction in urinary glycosaminoglycans (GAG). Safety was evaluated by compliance, adverse event (AE) reporting and adherence to treatment. Results: A significant reduction in urinary GAG (71–79%) was sustained. For the 12MWT, subjects in Phase 2 showed improvement of 255 ± 191 m (mean ± SD) at Week 144; those in Phase 3 Extension demonstrated improvement from study baseline of 183 ± 26 m (mean ±  SE) in the rhASB/rhASB group at Week 96 and from treatment baseline (Week 24) of 117 ± 25 m in the placebo/rhASB group. The Phase 1/2 6MWT and the 3MSC from Phase 2 and 3 also showed sustained improvements through the final study measurements. Compliance was 98% overall. Only 560 of 4121 reported AEs (14%) were related to treatment with only 10 of 560 (2%) described as severe. Conclusion: rhASB treatment up to 5 years results in sustained improvements in endurance and has an acceptable safety profile.
