Gene Therapy

Gene Therapy Manufacturing Solutions

Gene therapy – modifications on a patient’s genome, e.g. by integration and activation of new genetic material or the deactivation of disease-causing or faulty genes via a viral carrier – have allowed to set milestones in the therapy of a variety of even rare diseases. But although being applied in a more and more experienced manner also beyond clinical trials, genetic therapies will keep requiring the highest possible diligence.

Single Use Support GmbH provides biotechnology companies with specialized single-use solutions for gene therapies to optimize ATMPs (advanced therapies) manufacturing processes – from sterile single-use systems and customizable liquid management systems up to freezing and storing solutions.

Primary packaging for gene therapies

After gene therapy products such as viral vectors have undergone a gene editing process and have been cultured, they are not usually administered immediately. Instead, they must be safely stored ex vivo before they can perform the genetic modification for which they were designed, such as the replacement of a mutated gene or gene transfer.

To ensure the quality and safety of gene therapy products until they are transported to readministration, Single Use Support has developed single-use solutions in different sizes: For instance, RoSS.KSET is designed for the protection of smaller bioprocess containers, such as those needed for gene therapy, where smaller volumes need to be handled.

ROSS.KSET | Protecting small single-use bags

RoSS.KSET offers the protection for drug substances with volumes less than 250 mL. The shell of our CGT bag protection system is robust, closed, safe and sterile – most suitable for cell and gene therapies or clinical studies.

For larger volumes, RoSS can protect one or multiple single-use bags in one shell.

Store and ship anything from cell culture samples to large drug substance volumes reliably and on time.

Aseptic Filling and Draining of gene therapy products

To make sure that gene therapy works safely and effectively, the products that patients are provided with must be handled in a secure and sterile manner. This also applies to the filling and draining process, where the risk of cross-contamination and exposure to the environment must be avoided at all costs. Therefore, it is advisable to automate fluid management in gene therapies.

Single Use Support has developed dedicated gene therapy liquid solutions for safe and efficient filling and draining processes – the RoSS.FILL platform is the result of these efforts. The devices are available in different sizes, allow for high flexibility while speeding up turnaround time in gene therapy production.

Prevent downtime and ensure an uninterrupted supply chain in compliance with GMP and regulatory requirements with our single-use manifold assemblies using silicone tubing and connectors of your choice.

Controlled Freeze and Thaw processes for genetic therapies

Gene therapy products have very specific requirements for their freeze/thaw conditions, and an uncontrolled freezing process might cause irreparable damage to the product. Viral vectors, for example, are not only best stored at ultra-cold temperatures around -80 °C, but also need to be brought to this temperature at controlled cooling rates as they, too, are crucial to their quality.

Single Use Support has been innovating in this field and developed the RoSS.pFTU platform for optimized freezing and thawing of drug products. Based on plate freezing techniques, our freezers are available in different sizes, therefore suitable for various fields of application – be it the freezing of small volumes with RoSS.pFTU Lab Scale or the handling of larger volumes with the RoSS.pFTU Large Scale plate freezer, achieving temperatures as low as -80 °C. If even lower temperatures are required, the cryogenic freezer RoSS.LN2F can freeze products down to -150 °C.

Laboratory freezer RoSS.PFTU Lab Scale

RoSS.pFTU Lab-Scale | Plate Freeze & Thaw

1mL-10L: Laboratory freezer, compatible with single use bags of all sizes and manufacturers. Our lab freezer is the perfect solution for studies conducted in labs and, above all, if you want to start a controlled and scalable freezing process.

Gene therapy products – transport solutions

Before gene therapy solutions can be administered to treat various, often serious diseases such as leukemia or lymphoma, they must be transported and stored until the time they are needed. To ensure that they do not lose quality and safety over the time they are stored ex vivo, gene therapy products require special transport and storage solutions that also take into account the fact that space can sometimes be at a premium, while efficiency is key in cost and resource reduction.

To address this need, Single use Support has developed the ultra-cold storage freezer RoSS.FRDG, being a stackable device compatible with our protective equipment for single-use bioprocess containers, leading to an increased storage density. Additionally, Single Use Support has established RoSS.SHIP – a smart cold chain shipping container, able to keep temperatures below -60 °C for at least six days.
