Converting to a disposable system
Changing an existing reusable system to one that takes advantage of disposable technologies may not always seem to be an attractive
option. The investment already made in existing equipment may restrict the implementation of disposable technologies in some
facilities. However, even if it is considered to be impractical to invest in an entire disposable system, advantages can be
gained from introducing elements of the disposable systems previously described. For example, increasing the use of disposable
vessels (e.g., glass or plastic bottles and flexible bags) will potentially decrease turnaround times by reducing cleaning
requirements.
Conclusions
Disposable technologies in the manufacture of clinical supplies of biopharmaceuticals offer the benefit of reducing cost,
time, and risk. Some disposable technologies can be introduced into an existing facility quickly and at minimal cost. Savings
can be achieved in the manufacturing process, and time efficiencies can be realized. By taking advantage of the removal of
the requirement for cleaning verification when a fully disposable manufacturing equipment train is used, the time to get the
product to the clinical trial can be reduced by as much as two months. For some companies, this improvement may be the most
significant benefit of all.
