Early viral vector process development for cell and gene therapies is critical to assure a production strategy that supports commercial needs. In this webinar, you will learn the importance of planning for scalability and manufacturability from the earliest stages of process development and how a scalable templated process can reduce time needed to move from product development to commercialization. 

With increases in development and investments in the gene therapy field, companies will increasingly be looking at manufacturing and commercialization of their therapies. Road to commercialization goes through a series of process validation phases. In this webinar, we take a closer look at the road to commercialization and focus on addressing primary questions.

With the rise of gene therapy as a promising treatment modality, the industry is facing increasing pressure to decrease overall manufacturing costs, shorten product development timelines and increase production. This webinar focuses on intensified downstream process using high-productivity, single-use chromatography membrane adsorbers.

This presentation addresses product characterization strategies to de-risk the manufacturing of mAbs and cell and gene therapies. It also covers detection and characterization of host cell proteins (a factor in mAb therapies and cell and gene therapies), and polyethylenimine used in cell and gene therapies.

In this webinar, we discuss our strategies for developing lentivirus and adeno associated virus (AAV) and the impact these early decisions can have on commercial readiness.
