Clinical Trial Summary

This study evaluates camidanlumab tesirine in participants with relapsed/refractory Non-Hodgkin or Hodgkin lymphoma.

Description:

This is a Phase I, first in human clinical study with camidanlumab tesirine to evaluate the safety and tolerability and pharmacokinetics of camidanlumab tesirine in participants with relapsed/refractory lymphoma.

Camidanlumab tesirine is a human monoclonal antibody attached via a cleavable linker to a pyrrolobenzodiazepine (PBD) warhead which, when internalized by antigen expressing cells, covalently cross links deoxyribonucleic acid (DNA) preventing replication.

The study will be conducted in 2 parts: Part 1 (dose escalation) and Part 2 (expansion).
