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

Accumulation Index (AI) for Camidanlumab Tesirine

AI for HuMax-TAC, PBD-conjugated HuMax-TAC, and free warhead (SG3199). AI is the ratio of area under the serum concentration-time curve (AUC) from 0 to 21 days for Cycle 2 divided by AUC from 0 to 21 days for Cycle 1 (21 day cycle length). It is the increase in drug plasma concentration after multiple dosing until a steady state is reached.

Number of Participants With Anti-drug Antibody Response (ADA) Against Camidanlumab Tesirine

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.
