August 1, 2018/ Amgen breaks ground on $200M next-gen biopharma plant in Rhode Island, expected to be completed by 2020 The facility will feature a number of new manufacturing technologies and equipment that is smaller and portable, allowing Amgen to more quickly respond to changing demands in producing new medicines will allow the plant to be constructed in about half the time as well as reduce operating costs
The Benefits of Continuous Manufacturing
18
OPEX: operating expenses
CAPEX: capital expenses
Cost reduction!! Smaller footprint!!
19
Integrated Continuous Bio-manufacturing and Purification
Higher efficiency
Cost down
High product titer
Saves processing times
Constant product quality

Result in DCB
CAR-T Summary
We have established a serum-free culture platform to expand primary T cells and CAR-T cells to 20-125 folds of initial cell number in a 6-7-day culture (10-day process)and to 100-2500 folds in a 2-week culture (14-day process) ex vivo.
The T cell subsets in this serum-free culture condition were majorly early differentiated Th1 and CTLs.
Potential advantages: It can reduce the requirement of initial T cell number to perform basic
research or clinical treatment. Short operation time and high cell density could lead to the reduction of
occupancy of equipment and consumption of materials. Control of cell subsets at early differentiation stages might increase the
persistence and potency of CAR-T cells.
