KLK2

Unfortunately, that was a negative study, but we learned from the process.

Bispecific with the KLK2 tends to be a little bit better binding, right? So that's going to be taken off.

And then you also think about...

What about the antigen receptors to prevent small cell transformation with the variant histology? And so that's when you have the EZH2 that you lower the risk of lineage plasticity.
