Summary:

      This study evaluates ADCT-402 in participants with Relapsed or Refractory B-cell Lineage Non
      Hodgkin Lymphoma (B-NHL). Participants will participate in a dose escalation phase (Part 1)
      and dose expansion (Part 2). In Part 2, participants will receive the dose level identified
      in Part 1.
