Gary,
I know for one thing BMY knows a lot about NWBO. BMY had done plenty trials similar to what Linda Liau did but with more targets other than Glioblastoma before BMY came to NWBO for collaboration in 2017. I bet a serious vetting was done prior to the collaboration deal. If we look at the disclosure of the interests in the JAMA paper, those coauthors are also the consultants to other BPs. It is no surprise other BPs know NWBO well too. Why? I can see that after 2017 BMY signed the collaboration deal with NWBO. The BPs including Roche, Pfizer, Merck, AstraZeneca R&D on dendritic cells went hyperbolic. Immunotherapy is the ultimate way of curing cancer. All the BPs have tons of money. They will not hesitate for elephant-size deal if the technology is revolutionary. The way I see is that all the BPs who are enthusiastic about immunotherapy can form a JV with NWBO as the sole provider of the secret ingredient for various types of combo trials.
