DMOT4039A Q3W: Dose Escalation
Experimental
Participants in different cohorts will receive DMOT4039A at various escalating dose levels, starting with 0.2 milligrams per kilogram (mg/kg), as intravenous infusion every 3 weeks (Q3W) to determine the maximum tolerated dose (MTD) of DMOT4039A for until disease progression, loss of clinical benefit or unacceptable toxicity, whichever occurred first (up to approximately 2.5 years).
干预措施: DMOT4039A (Drug)
DMOT4039A Q3W: Dose Expansion
Experimental
Participants will receive DMOT4039A at recommended phase 2 dose (RP2D) for Q3W dosing schedule as intravenous infusion Q3W until disease progression, loss of clinical benefit or unacceptable toxicity, whichever occurred first (up to approximately 2.5 years).
