As gene transfer vehicles, lentiviruses exhibit many desirable properties, such as high transduction efficiencies, ability to infect both dividing and nondividing cells, and stable integration into the host cell genome. These properties make them well-suited for in vivo and ex vivo gene and cell therapies. However, cost-effective manufacturing of lentiviral vectors (LV) at commercial scales has proven difficult and remains a pressing issue for the marketing of therapies that depend on their application.
The production of viruses, whether for use as viral vaccines, viral vectors for gene therapy, or oncolytic applications, requires complex processes that can translate into high costs, as well as slow development timelines and time to market. This article presents several case studies highlighting the advantages of process intensification using Natrix® single-use membrane chromatography to increase your productivity and reduce your capital and operational manufacturing costs.
Lentiviral vectors (LVV) are a key component in the production of cell and gene therapies. 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. Here we break down DSP into unit operations and understand how process innovations are contributing to scalability at each step.

Overcoming technical challenges in the scale-up of LVV production is a major focus for the industry. This blog explores the principles that govern the scaling of upstream processing (USP).
There are many challenges with transfection-based protocols for producing LVVs at large scale. Here we will take a closer look at the use of stable producer cell lines as an alternative to transient transfection for the manufacture of LVVs.
In the field of cell and gene therapy, there are two main types of viral vectors: adeno associated virus (AAV) and Lentivirus (LV). The manufacture of these vectors is dependent on the regulatory requirements dictated by its end use. This blog outlines the challenges for optimization of scaled-up LV manufacturing processes and new technologies being used to solve these challenges.
Cellular immunotherapies (e.g. CAR-T cells) are primarily used as an autologous therapy to treat cancer. As such, these therapies are currently generated in small batches for each patient. To generate enough modified cells for a single treatment, cells are expanded in volumes from 1-10 L. In the final step of downstream processing (DSP) for immunotherapies, cells cultured in large volumes must be concentrated and reformulated into smaller volumes (e.g. 20-100 mL) suitable for delivery to patients. In this post, we will outline the key steps for concentration and reformulation and highlight specialized equipment needed for this critical unit operation.
CCRM is a full-service concept-to-market CDMO. We makes it easier for cell and gene therapy companies to accelerate commercialization of their emerging therapies and technologies at our full-service cGMP-compliant facility.
Exploring the use of automation in cell therapy and advanced therapeutic medicinal product manufacturing to improve safety, quality, and compliance is a key factor in advancing patient care.
To prepare the product for in-human testing clinical protocols are developed in consultation with the regulatory authorities, a target patient population is identified, clinical investigators and an appropriate contract research organization are selected, and funds are obtained. What is sometimes overlooked, or left to the last minute, is the less-than-glamorous, but still critical, manufacturing steps that ensure a new, potentially life-saving treatment reaches patients in a safe and reliable form. In this post we will map the five critical steps that require thoughtful measured consideration for a CGT product to be produced in a good manufacturing practices (GMP) facility.
