I don't know all the details of what can be gleaned from cell testing, but this is exactly what I thought should be happening. Get B into trials ASAP so it can be determined if it will be effective as a therapy. Do the human cell testing at the same time but move immediately into human trials since the cell test may not provide the overall picture of how B may impact the overall health of the patient. In actual trials is how we will know whether B actually works or not. There is no time to waste.....this is all in my opinion of course.
