The expansion is designed to meet growing industry demand for viral vector production.
The Hopewell facility is purpose-built to provide end-to-end AAV manufacturing solutions that align with global regulatory and quality standards. ProBio’s new capabilities offer clients fully integrated services—including GMP plasmid DNA production, AAV vector manufacturing, and final drug product formulation and aseptic fill/finish—within a single US-based location. The aim is to simplify coordination, reduce handoffs, and accelerate timelines across the drug development lifecycle.
“At ProBio, we recognize that every gene therapy program represents a critical opportunity to change lives,” said Allen Guo, CEO of ProBio.
“Our new GMP AAV manufacturing platform reflects our mission to help developers navigate complex manufacturing challenges with speed, precision, and scientific integrity.”
“The launch of our GMP AAV services is the result of deep cross-functional collaboration and reflects our commitment to delivering high-quality, end-to-end solutions for our partners,” said Michael Vreeland, US site head.
“Our experts have built and scaled manufacturing systems for some of the industry’s most advanced therapeutics, and they’re now applying that same expertise and dedication to every program at ProBio.”
Key Features of ProBio’s GMP AAV Manufacturing Services include:
Scalable, phase-appropriate manufacturing: Flexible batch sizes from 50L to 200L, with capability for 2x200L concurrent runs—supporting early clinical to late-phase programmes.
Fully integrated platform, single-site solutions: From plasmid production and AAV vector manufacturing to final drug product fill/finish, ProBio streamlines the entire process under one roof—reducing complexity, saving time, and accelerating developer’s path to clinic.
US-based supply chain: By prioritising domestic sourcing for key raw materials, ProBio said it ensures greater supply stability, faster lead times, and quality.
Accelerated timelines through in-house analytics: Internal QC and analytical capabilities enable fast, phase-appropriate release while maintaining standards of precision and compliance.
To enhance operational effectiveness and ensure seamless compliance, ProBio has embraced digitalisation through the implementation of a fully electronic quality management system (QMS) powered by Veeva. This system enables real-time electronic approval and traceability of key GMP documentation, including batch records, deviations, change controls, and CAPA events—supporting both regulatory alignment and execution speed.
“What differentiates our AAV platform is the combination of flexible manufacturing architecture and built-in quality by design,” said Lance Marquardt, Director of AAV Manufacturing Operations at ProBio.
“Our processes are engineered to support a wide range of serotypes, production scales, and clinical milestones—while ensuring rigorous in-process controls and regulatory alignment at every step.”
