9. For HCC participants only: Participants categorized to stage B (not amenable to locoregional therapy or refractory to locoregional therapy, and not amenable to a curative treatment), or stage C based on Barcelona Clinic Liver Cancer (BCLC) staging system
10. For HCC Subpart in Expansion Part only: prior systemic therapy for locally advanced or metastatic disease is as defined below
a. Participants who have received only one prior line of immuno oncology (IO) based regimen and have progressed on or after prior treatment with IO based regimen, or IO ineligible participants who have received no prior systemic therapy.
