Study Arms:
- ADCT-301 Monotherapy (Type: EXPERIMENTAL): In Part 1 (dose escalation) participants received escalating doses of ADCT-301 as monotherapy.~Camidanlumab tesirine is administered as a 30-minute intravenous (IV) infusion on Day 1 of each cycle. Participants treated with camidanlumab tesirine as monotherapy, in the initial dose cohort will receive 20 μg/kg Q3W and the highest dose was 150 μg/kg Q3W.
- ADCT-301 Combination Therapy (Type: EXPERIMENTAL): In Part 1 (dose escalation) participants received escalating doses of ADCT-301 in combination with pembrolizamab as combination therapy.~In Part 2 (dose expansion), participants received ADCT-301 in combination with pembrolizamab as combination therapy at the dose identified in Part 1 (dose escalation).~Participants treated with camidanlumab tesirine in combination with pembrolizumab, in the initial dose cohort received 30 μg/kg Q3W of camidanlumab tesirine.~Pembrolizumab was administered as a 30 minute IV infusion at a fixed dose of 200 mg (starting 1 hour after the end of the camidanlumab tesirine infusion).
