Summary

The primary objective of this study is to determine the recommended dosing regimen of loncastuximab tesirine in diffuse large B-cell lymphoma (DLBCL) or high-grade B-cell lymphoma (HGBCL) participants with moderate and severe hepatic impairment.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: ADC Therapeutics S.A.
• Treatments: Loncastuximab tesirine

Criteria

Inclusion Criteria:

• Male or female participants aged 18 years or older

• Pathologic diagnosis of relapsed (disease that has recurred following a response) or refractory (disease that failed to respond to prior therapy) DLBCL not otherwise specified, DLBCL arising from low grade lymphoma, and high-grade B-cell lymphoma (2016 World Health Organization classification) who have received at least one systemic treatment regimen

• Measurable disease as defined by the 2014 Lugano Classification

• Normal hepatic function or hepatic impairment as defined by the National Cancer Institute Organ Dysfunction Working Group hepatic impairment classification:

• Arm A Normal hepatic function: bilirubin and aspartate aminotransferase (AST) ≤ upper limit of normal (ULN)

• Arm B Moderate hepatic impairment: bilirubin > 1.5 × to 3 × ULN (any AST)

• Arm C Severe hepatic impairment: bilirubin > 3 × ULN (any AST)

• ECOG performance status 0 to 2 for participants with normal hepatic function. ECOG 0 to 3 for participants with moderate or severe hepatic impairment

• Adequate organ function

• Women of childbearing potential (WOCBP)* must agree to use a highly effective method of contraception from the time of giving informed consent until at least 10 months after the last dose of study drug. Men with female partners who are of childbearing potential must agree to use a condom when sexually active or practice total abstinence from the time of the first dose until at least 7 months after the last dose of study drug.
