As part of our continued expansion, this newly created The Associate Director, Downstream Process Development (PD) – Gene Therapy leads, and may actively contribute to, the engineering of downstream process development activities for gene therapy vector production. This includes, but may not be limited to, cell harvest and viral vector purification as well as small-scale DOE design and execution and manufacturing scale-up.
This individual leads the design and execution of scale-up studies from pilot through full clinical and commercial scale. S/he also functions as PTC’s Person in the Plant (PIP). In this capacity, s/he provides Subject Matter Expertise (SME) for internally executed processes, as well as external, Contract Development Manufacturing Organizations (CDMOs)-executed processes, to ensure their proper execution. S/he interacts extensively with Upstream Process Development, Analytical Development and Manufacturing personnel to deliver high-quality and robust downstream processes in a regulated environment.
S/he manages direct reports.
The incumbent works cross-functionally with internal departments and external resources as appropriate on downstream process development-related issues.
The Associate Director, Downstream Process Development – Gene Therapy supports adherence to relevant regulatory requirements and company Standard Operating Procedures (SOPs) as appropriate.
Provides leadership for, and may actively contribute to, downstream process development activities for both internal and external projects.
Functions as the PIP at CDMOs to monitor, and assist with, on-going downstream process development and execution activities.
Leads, and may also design and execute, small-scale depth filtration, UD/DF, and chromatography studies to support the development of viral vector and plasmid DNA-based gene therapy downstream purification processes.
Applies expertise with single-use bioprocessing equipment and its application to gene therapy downstream process development and GMP manufacturing and assists his/her direct reports (as appropriate) to develop/further develop their experience in these skills.
Works closely with Clinical Manufacturing to transfer downstream processes from PD to manufacturing.
Leads scale-up and tech transfer of downstream processes, supports process characterization and validation activities, writes reports and trains manufacturing personnel as required.
Collaborates with Analytical Development to build process understanding and design space via design and execution of in-process testing and control assays.
Works with Analytical Development to build the scientific knowledge, capabilities, and strategies in gene therapy product characterization that enable fast to clinic/fast to market product development and commercialization.
Leads, assures, and may actively contribute to, the effective execution of, science-driven, phase appropriate, and risk-based process development strategies to support development projects from candidate nomination to clinical development and commercial manufacture.
Leads, and actively contributes to writing and/or performing the QC review of relevant sections of global regulatory filings. These include, but may not be limited to, INDs, BLAs and ex-US filings
Manages, mentors, coaches and cross-trains junior scientists to build a highly functional PD Team that is cross-trained in at least two PD areas. This includes providing scientific and technical support to help troubleshoot and solve scientific challenges.
