It made headlines both sides of the pond. Based on the data (for RP2, as well as RP3), I'm still unsure.
Personally, I would like them to move forward with RP4 (+/- RP5), which has been engineered to secrete a next-gen anti-CTLA-4 [1] (similar to AGEN's), Flt3L (which recruits an important subset of DCs), and angiogenesis inhibitors (targeting the tumour vasculature) [4], in addition to some of the other 'payloads' they have added to RP1/2/3.
