About this study

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).

    Time frame: Day 1 to End of Study (a maximum of 12 months after last dose; median time on treatment was 43 days [min 1 day; max 354 days])

    An assay determines the presence of anti-ADCT-301 antibodies in human serum using a validated bridging electro chemiluminescence immunoassay (ECLIA) technique. The technique uses the drug itself to capture any anti ADCT-301 antibodies present in the serum. If anti-ADCT-301 antibodies are detected, they are confirmed to be specifically against ADCT-301 and then the level of the anti-ADCT-301 antibodies present in the serum is established using a modified version of the ECLIA technique.
