A number (three) will be TIP posters, so the only clinical update is going to be from the ongoing RP2 (+/- Opdivo) trial. It will be interesting to compare that to ONCR's ONCR-177 (initial clinical data also being presented at the same event), which uses a kitchen sink approach (the transgenes are Flt3L, IL-12, CCL4, anti-CTLA-4 and anti-PD-1, there are differences between the base viruses, but both use HSV-1).
No, it was the organisers, with data leaking via their site.
