As part of our plan of continued growth, in July of 2019, PTC is expanding and opening operations at the New Jersey Center of Excellence in Bridgewater NJ.
The Senior Scientist, Upstream Process Development (PD) – Gene Therapy leads, and actively contributes to, the engineering of upstream process development activities for gene therapy vector production. This includes, but may not be limited to, cell and virus culture as well as small-scale bioreactor process DOE design and execution.
The selected candidate will design and executes 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 external, Contract Development Manufacturing Organizations (CDMOs)-executed processes to ensure their proper execution. S/he interacts extensively with downstream Process Development, Analytical Development and Manufacturing personnel to deliver high-quality and robust upstream processes in a regulated environment.
S/he manages direct reports.
The incumbent works cross-functionally with internal departments and external resources as appropriate on upstream process development-related issues.
The Senior Scientist, Upstream Process Development – Gene Therapy supports adherence to relevant regulatory requirements and company Standard Operating Procedures (SOPs) as appropriate.
Provides leadership for, and actively contributes to, upstream process development activities for both internal and external projects.
Functions as the PIP at CDMOs to monitor, and assist with, on-going upstream process development and execution activities.
Designs and executes small-scale shake flask, 2-D multilayer flask and stirred tank bioreactor studies to support the development of cell, virus and plasmid DNA-based gene therapy upstream manufacturing processes.
Applies experience with fed-bath and perfusion cell culture in transfection- and infection-based viral vector gene therapy process development.
Applies expertise with single-use bioprocessing equipment and its application to gene therapy upstream process development and GMP manufacturing.
Works closely with Clinical Manufacturing to transfer upstream processes from PD to manufacturing.
Leads scale-up of upstream processes, 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.
Actively contributes to, and assures 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.
Actively contributes to writing and/or QC review of relevant sections of global regulatory filings. These include, but may not be limited to, INDs, BLAs and ex-US filings Supervises, mentors 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.
