WuXi Biologics Congratulates Amicus Therapeutics on European Commission Approval for Pombiliti™ in Patients with Late-Onset Pompe Disease

WUXI,China,March 28,2023 -- WuXi Biologics ("WuXi Bio") (2269.HK),a leading global Contract Research,Development and Manufacturing Organization (CRDMO),congratulates its strategic partner Amicus Therapeutics ("Amicus") (Nasdaq: FOLD) on receiving European Commission's approval for Pombiliti™ (cipaglucosidase alfa),a long-term enzyme replacement therapy (ERT) used in combination with miglustat for adults with late-onset Pompe disease (LOPD).

Pombiliti™ was started at WuXi Biologics in 2012 with just an initial concept and now realizes commercialization enabled by WuXi Biologics' proprietary integrated technology platform and unparalleled manufacturing capacity. Since 2019,WuXi Biologics has been providing commercial manufacturing services through "Global Dual Sourcing" strategy as the exclusive commercial drug substance manufacturing partner and key commercial drug product supplier.

"The joint efforts between Amicus and WuXi Biologics over past 11 years are just for this moment! We're honored to enable Amicus to achieve this great milestone,which will bring this new therapy to the patients with Pompe disease," commented Dr. Chris Chen,CEO of WuXi Biologics,"This provides another strong validation of our 'Follow and Win the Molecule' strategy that realizesour partners' ideas into commercialized medical treatments. Leveraging our world-class capabilities and robust global network,WuXi Biologics is accelerating and transforming how biologics are discovered,developed and manufactured globally to benefit patients worldwide."

The EC based the approval of Pombiliti™ on clinical data from the Phase 3 pivotal study (PROPEL),the only randomized,controlled trial in LOPD to include patients in the high unmet need ERT-experienced population,in addition to ERT-naïve patients. The EC approval of Pombiliti™ follows the positive opinion previously granted by the Committee for Medicinal Products for Human Use (CHMP).

About AT-GAA

AT-GAA is an investigational two-component therapy that consists of cipaglucosidase alfa,a bis-M6P-enriched rhGAAwhich facilitates high-affinity uptake through the M6P receptor while retaining its capacity for processing into the most active form of the enzyme,and the oral enzyme stabilizer,miglustat,that's designed to minimize loss of enzyme activity in the blood. In clinical studies,AT-GAA was associated with demonstrated improvements in both musculoskeletal and respiratory measures.

About Pompe Disease

Pompe disease is an inherited lysosomal disorder caused by deficiency of the enzyme acid alpha-glucosidase (GAA). Reduced or absent levels of GAA lead to accumulation of glycogen in cells,which is believed to result inthe clinical manifestations of Pompe disease. Pompe disease ranges from a rapidly fatal infantile form with significant impacts to heart function,to a more slowly progressive,late-onset form primarily affecting skeletal muscle and progressive respiratory involvement. Late-onset Pompe disease can be severe and debilitating,including progressive muscle weakness throughout the body,particularly the skeletal muscles and muscles controlling breathing,that worsens over time.
