Yes, HLA-A A2 phenotype is a required biomarker for enrollment.

Does this trial require EGFR?

Yes, EGFR sensitizing mutation is a required biomarker for enrollment.

Does this trial require ALK?

Yes, ALK fusion is a required biomarker for enrollment.

What disease stage is eligible?

Stage IV is required (metastatic disease required).
