Recent data on viral clearance design space & polish purification for Clinical Manufacturing

Natrix Separations is developing a platform of "plug and play" single-use-per-batch pre-packed chromatography chemistries and columns, offered as a pre-validated ready-to-use purification solution.

The presentation will discuss the most recent developments towards productive single-use-per-batch purification tools for downstream processing.

Traditional or disposable columns (which are not single-use) require significant capital investment, validation, inventory management, and labour. For typical Phase I-III manufacturing campaigns, the cost of materials (pass-through costs for purification, hardware and resin) can be 30-40% of the cost of manufacturing the product at a CMO. After 1-3 batches, those materials would not be needed for several years, often resulting in the discarding or retirement of the chromatography media and/or columns.

Because disposable membrane chromatography columns can be right-sized for the batch size being processed, they can be fully consumed and discarded after each batch, resulting in economic efficiencies and enabling quick changeovers for flexible manufacturing.

The webinar will describe Natrix’s hydrogel membrane technology, and show examples of applications for production of monoclonal antibodies. Recent data on viral clearance design space, polish purification for impurity reduction, and a process productivity model with some economic impact analysis will be presented.
