First-line PDAC participants will have received no previous systemic anti-cancer therapy. Second-line PDAC participants will have received no more than one prior systemic anti-cancer therapy.
First-line melanoma participants will have received no previous systemic anti-cancer therapy. Second- and third-line participants will have received and failed one or two prior systemic anti-cancer therapies, respectively.
NSCLC participants will have received at least one and no more than two previous lines of systemic therapy.
Combination therapy (both phases): PDAC participants will have received no previous systemic anti-cancer therapy for their advanced or metastatic disease.
