EFFICIENT SCALE-UP OF IPS CELLS FOR AUTOLOGOUS CELL THERAPY WORKFLOW

Project Summary/Abstract Cell expansion is a critical step for cell therapy, hindered by expensive and complex bioreactor requirements to yield sufficient cell numbers for adequate dosing and requiring expensive regents to enhance functionality for increased clinical success. To support the use of patient cells within the cell therapy workflow, there is a need

for bioreactors designed for expanding patient cells from an initial iPS clonal population to clinically relevant cell doses. These reactors must also be suitable for cGMP processes and economically efficient to enable their utility within the healthcare system. Overall, there is a need for clinically relevant cell expansion technologies that are

robust and efficient enough to enable the realization of autologous cell therapy workflows as a viable treatment option for all. Thus, the unmet need we will address is providing a bioreactor-based workflow for the efficient translation of patient cells into high-quality iPS cell based therapeutics in a patient-specific manner – benefiting

drug developers, patients, clinicians, and the healthcare economy. Our universal approach to cell expansion (OnXpansion) uses a defined serum-free media and relies on controlled aggregation for enhanced paracrine signaling and cell-cell contact, enhanced nutrient delivery via low-shear perfusion, and organotypic tissue niches

to generate thousands of identical spheroid tissues that can be further scaled to yield adequate cell numbers for cell therapy at both reduced costs and manual labor. Our approach to translating this technology center around de-risking its utility for precision medicine and increasing its suitability and handling within the intended

customer workflows. Our bioreactor products are efficient (cost, time, labor), easy to use, automated, reliable, robust, physiologically relevant, and clinically predictive. The large unmet need and low barrier for entry positions Link favorably against competitors. Overall, Link’s products are designed to enable a reliable and robust

precision medicine workflow that is efficient and of high biological fidelity, thereby enabling a future where cell therapy is more accessible to the patient, via decreased costs, and the provider, via simplified workflows.
