It is not that simple. Here is the real story of who developed what.

In the mid 90s Boynton ran the P1/2 trials with DC Prostate. This was/is a specific antigen DC so not ATL based. Sometime in the late 1995-2001 time frame NWBO had developed a process for ATL based DCs that used freeze-thaw cycles to extract the lysate and freeze the final product. The differentiating agents were GC-CMF and IL-4 as was common. I am not aware of any clinical trials at that time.

In the mean time, around 1999 LL, Prins, Cloughsey et all ran a P1 with a fairly standard version of ATl-DC, used an acid bath to extract the lysate. Imature DCs were frozen and thawed for each dose to be matured via the lysate. The use of GM-CSF and IL-4 was described in a referenced paper for 1996 that had nothing to do with NWBO.

In 2001 NWBO contracted with UCLA to perform clinical development of NWBO's version. This work did not use UCLA's version, and was not changing the product. It was designing and then running the early trials.

So we are talking 2 different agents. One by each side. Yes, LL did work on the clincial side of the DCVax-L program, but UCLA has no ownership in it. Nor does NWBO have any ownership of the UCAL based ATl-DC that was developed prior to the NWBO/UCLA contract.
