Process Development

We provide comprehensive process development services to help transition your research-grade process into a scalable, cGMP-compliant manufacturing process for cell and gene therapy.

Over the past two decades, gene therapy research and development have advanced significantly. The biopharma industry faces an increasing demand for viral vectors in cell and gene therapy, with heightened expectations for higher quality, improved manufacturing processes, higher titers, and greater yields.

To meet these challenges, Andelyn’s process development scientists focus on creating cost-effective, robust, and scalable platforms that support both clinical and commercial applications. By integrating quality-by-design (QbD) principles, we help accelerate timelines, optimize costs, and ensure reliable manufacturing processes from early-stage development to large-scale production.

Our team remains at the forefront of innovation, continually evaluating emerging technologies and developing new strategies to improve production, purification, and product quality. Collaborating closely with the analytical development group, we implement orthogonal analytical methods to ensure comprehensive product characterization at every step of the process, avoiding reliance on a single technique.


This commitment to excellence empowers us to deliver tailored, scalable solutions that advance the field of cell and gene therapy while meeting the demands of both early-stage and large-scale programs.

Process Optimization for Suspension and Adherent Systems

  • Use scale-down models for efficient production processes.
  • Optimize yield/recovery, capsid separation, and critical quality attributes.
  • Ensure reproducibility, scalability, and smooth transfer to cGMP manufacturing.
