I think it's on or off, but little chance of being able to make it 25%, 50% or 75% on. That's a level of control that will be very difficult to achieve.
Above my pay grade to quibble, however I would point out the following from BLCM's website:
In addition to using our CaspaCIDe technology for the substantial elimination of cellular therapy, like an “off” switch, we are studying partial elimination of a cellular therapy, like a “dimmer” switch, by delivering reduced doses of rimiducid. We observed the dose response to rimiducid by measuring the viability of BPX-501 cells in culture following the addition of increasing amounts of rimiducid to the culture medium, as well as by measuring the survival of BPX-501 cells in vivo in immune-deficient mice following injection of increasing doses of rimiducid. In these preclinical studies, rimiducid rapidly and consistently reduced or eliminated CaspaCIDe-containing cells in a dose-dependent manner.
I have read a lot and the IV ziop board has some good info as well as the publications out there...some studies also show under MD Anderson and other corraborators etc
I really think that Dr. Cooper is well regarded and has first hand knowledge of CAR, NK, TCR and if you would read some of his work and publications - i think that you would agree as well.
I have been trying to raise awareness on the biotech board as to this company, recent modifications to their agreement with XON which portend to a large deal for ZIOP, buyout etc
With regards to IL-12 - its been in the public domain for 20-30 years and yet nobody has been able to control the CRS etc....ZIOP did in their glioma studies and reversed grade 3-4 toxicities etc
