Background
At the start of the pandemic, a call to action to the pharma/biopharma industry was made to quickly develop vaccines and treatments to the COVID-19 virus. Multiple companies responded by discovering several promising neutralizing antibodies to SARS-CoV-2 and due to our true, one-stop, integrated and efficient antibody CMC development platform, these companies requested expedited product development to get their much-needed biologics into the clinic and on to patients in need.
Challenge
To work with our clients and the global regulatory agencies to develop a record-breaking CMC development and GMP manufacturing timelines without compromising product quality and also meet the stringent CMC regulatory requirements.
Solution/Results
In the peer-reviewed articles presented here and here, we report a novel Chemistry, Manufacturing, and Control (CMC) workflow and demonstrate a significantly shortened timeline of 3-6 months from DNA to Investigational New Drug (IND) application for seven different antibody programs. Several of these programs went on to receive Emergency Use Authorization (EUA) approval in less than two years. In summary, due to the vast experience, process understanding and technology platform knowledge of the WuXi Biologics WuXia CHO-K1 cell line development platform, materials generated from stable pools under GMP conditions were used for rapid initiation of phase I clinical trials in approximately 3 months. Clones with comparable product quality as pools were subsequently selected for further development and manufacturing and enabled an IND application filing within 6 months. Stability studies on the critical path were allowed a shorter duration prior to IND filing thus greatly reducing the time required for final clone determination (extended stability data would be provided on a rolling basis to the regulatory authorities) . NGS-based viral testing was routinely used for rapid conditional release of the Master Cell Bank (MCB) for GMP production (with more comprehensive CLC characterization per ICH guidelines provided on a rolling basis to the regulatory authorities). The successful execution of these COVID-19 programs relied on our robust, fit for purpose, and highly-vetted CLD platform.
