RoosterBio, a leading supplier of human mesenchymal stem/stromal cells (hMSCs), highly engineered media, development services, cell engineering, and advanced therapy bioprocess solutions, today announced that it has selected Repligen Corporation, a life sciences company focused on bioprocessing technology leadership, as a collaboration partner to advance scalable exosome bioprocessing.
RoosterBio’s goal, in collaboration with Repligen, is to deliver solutions for manufacturing of exosomes using scalable and low shear technologies that enable cost-effective commercialization of these advanced therapies.
There has been a growing demand in exosomes supply in recent years due to their emerging role as intercellular messengers and their therapeutic potential as targeted and natural drug delivery vehicles with high specificity and efficiency. The complexity and fragility of the exosomes, scalability, yield, and purity of production processes are challenges to meeting demand. The combination of Rooster Bio’s and Repligen’s scalable platforms are being advanced to overcome those challenges.
RoosterBio is leveraging its well-established technology platform including hMSC cell banks and highly engineered bioprocess media to generate representative bulk exosome product in stirred tank bioreactors at 3L scale. Repligen’s KrosFlo® TFDF and hollow fiber KrosFlo® TFF systems enable highly efficient and scalable, clarification and concentration steps to significantly improve potent exosome yields. Repligen also brings to the collaboration the ability to develop exosome affinity resins for product purification. The exosomes are being evaluated for quality, purity and potency utilizing RoosterBio’s extensive panel of analytical characterization techniques.
The results to date of the RoosterBio/Repligen collaboration, which began in September 2022, clearly demonstrate at small scale the benefit of Repligen’s integrated automated single-use platform for high recovery yield of functional hMSC exosomes during clarification and concentration steps.
The combination of RoosterBio off-the-shelf cell and media products, and analytical characterization capabilities, along with Repligen filtration and purification technologies makes possible a manufacturing scale, cGMP compatible platform to help address increased global demand for exosomes.
“Exosomes are an emerging therapeutic modality that has the potential to create transformational impact on human health, while also posing a unique set of manufacturing and analytical characterization challenges. We are thrilled to partner with Repligen to accelerate our customers’ path to the clinic and enable successful commercialization of innovative exosome therapies,” said Tim Kelly, Chief Executive Officer of RoosterBio.
“We started this collaboration last year and the results to date are very encouraging. We believe that this joint collaborative effort will provide commercially and clinically viable scalable solutions for exosome manufacturing,” said Vikas Gupta, VP & GM, Downstream Bioprocessing and Gene Therapy of Repligen.
Both companies will investigate extending these studies from laboratory scale to pilot and manufacturing scales, enabling the manufacturing, clarification, chromatography, and concentration of exosomes for even the largest advanced therapy indications.
