64x Bio, a biotechnology company focused on scalable solutions for advanced therapy production, has officially launched AAV Apex Suite, a high-performance product line aimed at solving one of gene therapy’s most pressing issues: manufacturing constraints. The launch follows the formation of strategic collaborations with five leading global biopharma and CDMO partners, underscoring industry demand for improved viral vector production.

Gene therapies hold transformative potential, but their reach has been limited by high manufacturing costs and low scalability. AAV Apex Suite tackles this challenge head-on, offering suspension-adapted HEK293 cell lines optimized for transient transfection and delivering titers exceeding E15 vg/L. These results have been independently validated across various serotypes and therapeutic payloads, consistently achieving high yield and quality.

"The grand challenges for gene therapies have shifted from target organ specificity and how to fit large genes into small capsids to the challenge of low-cost, high-quality manufacturing of AAV therapies. So it is with great pleasure that we see this milestone from 64x," said George Church, PhD, Co-founder of 64x Bio.

The AAV Apex Suite is powered by 64x Bio’s VectorSelect platform, an advanced system that maps the cellular pathways driving productivity. VectorSelect combines genetic and metabolic profiling to guide both cell line engineering and media formulation. As the platform’s dataset continues to grow, 64x Bio is applying computational tools to refine and accelerate new product development.

“Our goal is to enable gene therapies and next generation medicines to succeed by fixing the cost and scale problems that hold them back,” said Lexi Rovner, PhD, CEO and Co-founder of 64x Bio. “Our team has done incredible work to develop AAV Apex Suite as an initial demonstration of what our platform can achieve. We’re already building on this foundation and continuing to develop more that we’ll be sharing soon,” she added.

The launch of AAV Apex Suite comes at a critical time for gene therapy manufacturing. Five prominent biopharma and CDMO partners have already committed to collaborations, highlighting the urgency to resolve production limitations. While AAV Apex Suite currently supports transient production, 64x Bio is actively developing stable cell lines, with plans to expand the suite further.

Beyond the off-the-shelf capabilities of AAV Apex Suite, the company is also offering custom solutions through its VectorSelect platform. These custom projects extend beyond AAV, as 64x Bio continues to explore applications in broader advanced biologics manufacturing.

viral vector production

Viral vector manufacturing is the process of producing viral vectors, which are modified viruses used to deliver genetic material into cells for various applications like gene therapy and vaccine development. The process involves several key steps: vector design, where the therapeutic gene is incorporated; host cell selection and genetic engineering; cell cultivation in bioreactors; virus production; harvesting; purification to remove impurities; quality control to ensure safety and potency; and formulation into a usable product.

Key aspects of viral vector manufacturing:

Vector Design:

Selecting the therapeutic gene and incorporating it into the viral vector's genome, while ensuring the vector is replication-deficient to prevent disease.

Host Cell Selection and Modification:

Choosing suitable host cells (e.g., mammalian cells) and genetically engineering them to produce the desired viral vector.

Cell Cultivation:

Growing the modified host cells in bioreactors under controlled conditions.

Virus Production:

The cells produce the viral vectors during cultivation.

Harvesting and Purification:

Separating the viral vectors from the host cells and purifying them to remove impurities like empty capsids and host cell proteins.

Quality Control:

Rigorous testing to assess the safety, potency, and purity of the final product.

Formulation:

Preparing the purified viral vectors into a stable dosage form for storage and administration.

Challenges in Viral Vector Manufacturing:

Scalability:

Scaling up production from research to commercial levels is a significant challenge.

Cost:

Manufacturing viral vectors, particularly using adherent cell culture, can be expensive.

Purity and Consistency:

Ensuring high purity and consistency of the viral vector product is crucial for safety and efficacy.

Process Development:

Optimizing the upstream and downstream processes is essential for efficient and cost-effective production.

Regulatory Compliance:

Meeting stringent regulatory requirements for viral vector manufacturing is vital.

Types of Viral Vectors:

Retrovirus: Capable of stably integrating into the host genome.

Lentivirus: Can integrate into the genome of non-dividing cells.

Adenovirus: A DNA virus that replicates in the cell nucleus.

Adeno-associated virus (AAV): A small DNA virus that can infect both dividing and non-dividing cells.

Oncolytic viruses: Viruses that selectively kill cancer cells.

Emerging Trends:

Suspension-based systems:

Moving towards suspension cell culture for increased scalability and cost-effectiveness.

Single-use technologies:

Utilizing disposable bioreactors and other components to reduce contamination risks and improve efficiency.

Process analytical technologies (PAT):

Implementing PAT to monitor and control the manufacturing process in real-time.

Advanced purification methods:

Developing more efficient and robust purification techniques to improve product quality

simulations of viral vectors for gene therapy

Simulations of viral vectors for gene therapy involve using computational models to predict and optimize the behavior of these delivery vehicles. These simulations help researchers understand how viral vectors interact with cells and tissues, their potential toxicity, and how to improve their efficacy and safety. By modeling various factors like vector design, cellular environment, and immune response, these simulations guide the development of more effective and targeted gene therapies.

Here's a more detailed look:

What are Viral Vectors?

Prospective approaches to gene therapy computational modeling ...

Viral vectors are essentially modified viruses used to deliver therapeutic genes into cells. They are designed to be safe and efficient delivery systems, replacing the virus's natural disease-causing genes with the desired therapeutic gene.

Why are Simulations Important?

Optimizing Vector Design:
Simulations allow researchers to test different vector designs, such as capsid types (e.g., AAV, lentivirus) and promoters, virtually before moving to costly and time-consuming experiments.
Predicting Immune Response:
Simulations can model how the body's immune system will react to the viral vector, helping to minimize potential adverse reactions.
Targeting Specific Cells and Tissues:
Simulations can help optimize the targeting of viral vectors to specific cell types or tissues, improving the effectiveness of gene therapy.
Assessing Safety:
By simulating various scenarios, researchers can identify potential risks associated with viral vectors and develop strategies to mitigate them, ensuring the safety of gene therapy treatments.
Guiding Clinical Trials:
Computational models can help design more efficient and informative clinical trials by predicting optimal dosages, delivery routes, and patient populations.
