Treatment Arms

ArmTypeDescription
Part 1: Dose EscalationEXPERIMENTALIn Part 1 (dose escalation) participants with selected advanced solid tumors will receive escalating doses of ADCT-901 as monotherapy. Participants can receive ADCT-901 until disease progression, adverse event (AE), or other discontinuation criteria, whichever occurs first.
Part 2: Dose ExpansionEXPERIMENTALIn Part 2 (dose expansion), participants will receive ADCT-901 monotherapy at the dose identified as the RP2D/MTD in Part 1 (dose escalation). Participants will be split into two groups: Group 1: An indication for which ADCT-901 showed in Part 1 to have preliminary activity. Group 2: A group of participants with Part 1 indications, except for the one selected in Group 1 of Part 2. No more than 30% of participants with the same indication are allowed in this basket group. Participants can receive ADCT-901 until disease progression, AE, or other discontinuation criteria, whichever occurs first.
