I realize what you're saying, but I'm proposing a different business model is possible and the disposable cassettes would completely track it's production even if it's made in thousands of sites. It's rather like a drug made at a compounding pharmacy. I don't know exactly how drug makers are paid when their drugs are compounded at these pharmacies, but if you have a prescription, what you get ought to be essentially the same regardless of what compounding pharmacy makes it.
I'm not saying the company will do it, but I do believe it could be considered. I know at City of Hope they were making their own CAR-T products before commercial products were available, I don't know if they still are today, but individualized drugs developed there have been saving lives for many years as I understand it. Every batch of DCVax-L or Direct is different from every one they've ever made, I don't see where it's made mattering very much as long as the facility and people are qualified to make it.
The technology NWBO represents a new paradigm in treatment, no matter where it's made each batch will be distinctive, it cannot be made in a mass produced manner.
