I don't think so. If you recall, there already was an anti-pd-1 immunopulse combo mouse trial last year which showed 100% response on all subjects, so i would think we would go right into human.
Plus this has already been verified through their past presentations and correspondence in the addition of anti-pd-1s to our Phase 2B for melanoma (which i assume will start after final data is presented)
+ the addition of a new clinical trial for a new indication will likely be a combo trial
