High Productivity Harvest: Novel strategy for intensifying harvest and displacing depth filtration in fed-batch cell culture

11:15 AM

Dr. Kerstin Lange, Team Leader Process Technology, Alvotech


Alvotech developed an intensified Fed-batch process using the XCell™ ATF technology for the production of a complex fusion protein. The process uses the novel technique of High Productivity Harvest (HPH), which involves a traditional Fed-batch process and a clarification process using the XCell™ ATF System. Implementing the new process resulted in higher vcd and viability, improved product quality, and a reduction of cost of manufacture compared to the conventional Fed-batch process.

Process development and manufacturing of Antibody-Drug Conjugates (ADCs) using single-use technologies

01:45 PM

Ruud Verstegen, Downstream Bioprocessing Process Engineer, Synthon Biopharmaceuticals


Antibody–Drug Conjugates (ADCs) consist of a monoclonal antibody linked with a highly potent cytotoxic drug. The antibody primarily targets the drug to tumor cell receptors and secures internalization while the cytotoxic drug kills the targeted tumor cells.

Protecting both the product from environmental contaminants and the staff from exposure to the drug product are key manufacturing quality measures. While glass and stainless-steel systems may effectively protect operators, they require significant equipment decontamination and cleaning validation. As an alternative, single-use technologies offer specific benefits, but also come with their own challenges. Approaches and challenges to safe handling of both antibodies and high potency molecules (ADCs, cytotoxic linker drug) will be presented.

Speaker Bio

Ruud Verstegen is DSP Process Engineer at Synthon Biopharmaceuticals based in Nijmegen in the Netherlands. He studied biochemistry at HAN University of Applied Sciences and has over 15 years work experience in the biopharmaceutical industry. His work experience includes development of veterinary viral vaccines at MSD Animal Health and development of human bacterial vaccines at Nobilon (Merck). Since 2011, he has worked within the Down Stream Processing department at Synthon BV and is involved in process development for production of antibodies and antibody drug conjugates including scale-up, tech transfer to a GMP manufacturing facility and process validation.
