iSpy 2: A Platform Trial

iSpy 2 is a platform trial, it's ongoing. It gives us the opportunity to continue to add new agents in a series of ways. We use MRI, functional tumor volume, and biopsy when appropriate to predict who's going to have a complete response. But importantly, if someone doesn't look like they're having an appropriate response by six weeks we have a strategy where you can escalate early and move on.
