Study Arms:
- Part 1: ADCT-402 dose escalation (Type: EXPERIMENTAL): In Part 1 (dose escalation) participants will receive intravenous (IV) infusions of ADCT-402 at escalating doses, according to a 3+3 study design. Doses will be escalated from 15 µg/kg to 200 µg/kg on Day 1 of each cycle, with cycle lengths of 3 or 6 weeks.
- Part 2: ADCT-402 dose expansion (Type: EXPERIMENTAL): In Part 2 (expansion), participants will be assigned to the recommended dose level(s) and schedule(s) of ADCT-402 identified in Part 1 by the Dose Escalation Steering Committee.~Participants will receive intravenous (IV) infusions of ADCT-402 at either 120 μg/kg or 150 μg/kg on Day 1 of each 3 week cycle (Q3W).

Based on this trial design, predict the completion outcome and termination type (if applicable).
