Developing cell lines is a vital component of biopharmaceutical manufacturing. High productivity already at non-clonal pool stage, comparability of product quality between non-clonal pools & clonally derived cell lines and a robust & scalable USP platform process which is suitable for non-clonal pools and equally clonally derived cell lines, are crucial for reducing CMC timelines from the start of development to Drug Substance.
Today, we routinely utilize non-clonal pools to either evaluate lead molecule candidates (e.g. regarding expressability and product quality) or optimize expression vectors before starting CMC activities in so-called non-clonal pool based PoC studies. Beyond that, we deploy non-clonal pools in active programs for early material supply. Looking ahead, a future vision is to apply non-clonal pools up to GMP manufacturing for early clinical phases.
Sebastian Schwamb is Senior Director of Process Science at CDMO Rentschler Biopharma. Since joining the company in 2020, he has overseen cell line development, genotypic characterization, and early-stage USP development.
With over 15 years of experience in cell line and upstream process development, Sebastian is a seasoned professional. His expertise extends beyond the CDMO sector, having worked in big pharma at Sanofi, small biotech at Ganymed Pharmaceuticals (a predecessor of BioNTech), and academia at TUM and Mannheim University of Applied Sciences in collaboration with Heidelberg University.
His passion lies in understanding and optimizing processes, from nurturing stable producer pools and cell lines to achieving scalable USP processes.
