Inclusion Diagnosis Phase 1 - Histologically or pathologically confirmed locally recurrent or metastatic advanced malignancy; Phase 2a Part 1 i. Arm A - locally recurrent or metastatic melanoma. Participants must have received no more than 3 prior regimens for advanced or metastatic disease; Arm B - locally recurrent or metastatic HNSCC. It must also meet the following criteria: 1) Disease progression to platinum-containing chemotherapy; 2) Failure to anti-PD-1/PDL1 blockade after receiving at least 2 doses alone or in combination; Arm C - Sarcoma. Participants must have received no more than three lines of prior anti-cancer therapies; Arm D - locally recurrent or metastatic cSCC. Participants must have received no more than 3 prior regimens for advanced or metastatic disease; Phase 2a Part 2 i.v. Arm E - Histologically or pathologically confirmed NSCLC that is advanced or recurrent, without EGFR mutation or ALK rearrangement. Participants must have received at least one line but no more than three lines of prior anti-cancer therapies
