WuXi AppTec's Changzhou and Taixing API Sites Successfully Pass FDA Inspections

SHANGHAI, March 31, 2025 /PRNewswire/ -- WuXi AppTec, a global company that provides a broad portfolio of R&D and manufacturing services to enable companies in the pharmaceutical and life sciences industry, today announced that its Active Pharmaceutical Ingredient (API) manufacturing sites at Changzhou and Taixing in Jiangsu province of China, successfully passed U.S. Food and Drug Administration (FDA) inspections back-to-back in March — both without a single observation and with no Form 483 issued. These achievements further demonstrate WuXi AppTec's unwavering commitment to upholding the highest quality standards and to supporting global healthcare innovators in reliably delivering needed therapies to patients worldwide.

The Company's API site at Changzhou underwent a GMP surveillance inspection by the FDA that began on March 4. Covering 21 FDA-approved products, the inspection followed the FDA's six-system inspection model. The FDA inspectors concluded the review one day ahead of schedule. No observation was raised.

On March 21, 2025, the API site at Taixing also completed a Pre-Approval Inspection (PAI) for the commercial manufacturing of a peptide-based therapeutic, with no observation. The site presented its state-of-the-art infrastructure, the team's strong technical expertise, and the high level of compliance demonstrated through its systems, documentation, and records. Operational since September 2023, the 169-acre Taixing site is the company's newest and largest API manufacturing facility. The successful inspection confirms the site's readiness to support commercial API supply to the global market.

"Our team's consistent focus on quality and compliance is key to enabling our global partners," said Dr. Minzhang Chen, Co-CEO of WuXi AppTec. "We're pleased that both the Changzhou and Taixing sites passed their FDA inspections with no observation. These successful results further reinforce WuXi AppTec's dedication to providing high-quality R&D and manufacturing solutions that support our customers worldwide in accelerating new drug development and commercialization for the benefit of patients."

The Changzhou and Taixing sites are critical manufacturing bases of WuXi STA, the company's small molecule CDMO platform, and WuXi TIDES, which provides integrated CRDMO services for oligonucleotides, peptides, and synthetic conjugates. Both sites support the manufacturing of APIs and intermediates across a wide range of chemical modalities.

WuXi AppTec continues to invest in capacity expansion to meet growing global demand. The company's investment in its Couvet, Switzerland, site resulted in doubling oral dose capacity over the course of 2024. Meanwhile, WuXi AppTec continued to build its U.S. (Middletown, DE) site, which is expected to commence operations by the end of 2026. In May 2024, the company announced the groundbreaking of Singapore R&D and manufacturing site; Phase I expects to commence operations in 2027.
