Since Mirus launched RevIT? AAV Enhancer in late July 2023, the integration of RevIT? AAV Enhancer has enabled a 1.2- to 4.9-fold increase in genome titers of AAV vectors across different serotypes. It has also improved vector infectivity to a certain extent, making it possible to further reduce upstream costs in AAV production and lowering the cost per dose of gene therapies. Owing to its ease of flexible integration into existing AAV manufacturing workflows—being compatible not only with Mirus’ TransIT-VirusGEN® GMP transfection reagent but also with other transfection reagents (e.g., PEI)—RevIT? AAV Enhancer has gained widespread recognition and acclaim from AAV clients both domestically and internationally. Additionally, the GMP-grade reagent has been launched as scheduled for large-scale GMP-compliant AAV production.

 

The GMP-grade RevIT? AAV Enhancer was released on September 30, 2024. Manufactured in a facility certified under the ISO 13485 system, it complies with ISO 20399 and USP <1043> standards. Since its launch on July 28, 2023, RevIT? AAV Enhancer has been proven to increase viral titers by at least 2- to 4-fold across different AAV serotypes, cell culture media, and transfection platforms. While maintaining high-quality titers, it allows for reduced plasmid DNA usage, thereby significantly cutting down AAV vector production costs.

Poster Data: Optimizing Key Parameters for AAV5 Clinical Manufacturing: Enhancing Process Productivity and Drug Substance Quality (Link)

In this poster, Bridgebio shared data on viral titer and infectivity (left panel) for the AAV5 serotype during scale-up from shake flask to 200L (125mL shake flask → 2L → 10L → 200L), using TransIT-VirusGEN® transfection reagent and RevIT? AAV Enhancer. Compared with the previous process (Process A: PEIPro transfection + Expi293 cells/media), the processes using TransIT-VirusGEN® transfection reagent as a replacement (Process B: TransIT-VirusGEN® transfection reagent + Expi293 cells + BalanCD medium; Process C: TransIT-VirusGEN® transfection reagent + VP2.0 cells + BalanCD medium) achieved higher viral titers (right panel) and lower residual host DNA and plasmid DNA.

New Product Express

The TransIT®-AAViator Transfection System is developed based on Mirus Bio's patented and mature polymer and lipid technology platform. Compared with transfection reagents based solely on polymers (PEI), it can further increase the yield of AAV vectors and allows a 50% reduction in plasmid DNA usage. The TransIT-AAViator System consists of the new TransIT-AAViator Transfection Reagent and RevIT? AAV Enhancer. When used in combination, they significantly optimize upstream transfection—a key step in AAV manufacturing—maximizing AAV titers. Stay tuned for more details.
