May 2017 - Apr 2020
Key scientist in the antibody discovery group in this US/UK-based antibody therapeutic company: • Key project team member and sole molecular biology resource for AGEN1423, a novel immuno-oncology antiCD73/TGFβ-trap bispecific antibody that was filed for IND at the end of 2018 and was licensed to Gilead for $150m. • The key molecular biology resource for a high-priority bispecific project targeting NK cells that is advancing to IND by end of 2020. • Design and generate strategies for lead antibody clone sequence optimization in record speeds – affinity maturation, humanization, sequence liability removal, developability profile improvements. • New process development and implementation – high throughput molecular cloning methodology allowing rapid antibody and antibody fragment clone conversion from scFv to IgG for mammalian expression and characterization. • Establish collaborations to enable access to external services – gene synthesis and molecular cloning outsourcing, custom cloning reagent sourcing. • Organization and upkeep of valuable and useful reagents for functional and cross-functional groups. • Regularly presenting at global project team meetings to update on plans and progress, and at UK site meetings to share best practices and troubleshoot issues. • Organizing and chairing monthly site-wide seminars. • Cross-site Health and Safety committee member – discussing and implementing guidelines for proper equipment and process use, point-of-contact for functional group regarding H&S questions/issues.
