Lentiviral vectors (LVV) are a key component in the production of cell and gene therapies. They are most often used to deliver genetic material that will modify cells and confer therapeutic properties. Today, even with the proliferation of cell and gene therapies in development, LVV is still produced using legacy methods employed in basic research. Overcoming technical challenges in the scale-up of LVV production is a major focus for the industry. Scalable LVV production platforms are critical for manufacturing affordable cell and gene therapies and making them more widely available. For an overview of LVV manufacturing and process optimization considerations see our previous post.
We will start our series on LVV scale-up by exploring the principles that govern the scaling of upstream processing (USP).
