Inclusion Criteria

1. Male or female patient aged 18 years or older
2. Pathologic diagnosis of DLBCL, as defined by the 2016 WHO classification, to include: DLBCL not otherwise specified; primary mediastinal large B-cell lymphoma; and high-grade B-cell lymphoma, with MYC and BCL2 and/or BCL6 rearrangements
3. Relapsed or refractory disease following two or more multi-agent systemic treatment regimens
4. Patients who have received previous CD19-directed therapy must have a biopsy that shows CD19 protein expression after completion of the CD19-directed therapy
5. Measurable disease as defined by the 2014 Lugano Classification
6. Availability of formalin-fixed paraffin-embedded (FFPE) tumor tissue block (or minimum 10 freshly cut unstained slides if block is not available)
7. ECOG performance status 0-2
8. Adequate organ function as defined by screening laboratory values within the following parameters:
a. Absolute neutrophil count (ANC) =1.0 × 10^3/µL (off growth factors at least 72 hours)
b. Platelet count =75 × 10^3/µL without transfusion in the prior 7 days
c. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma glutamyl transferase (GGT) =2.5 × the upper limit of normal (ULN)
d. Total bilirubin =1.5 × ULN (patients with known Gilbert’s syndrome may have a total bilirubin up to =3 × ULN)
e. Blood creatinine =1.5 × ULN or calculated creatinine clearance =60 mL/min by the Cockcroft and Gault equation
9. Negative beta-human chorionic gonadotropin (ß-HCG) pregnancy test within 7 days prior to start of study drug (C1D1) for women of childbearing potential
10. Women of childbearing potential must agree to use a highly effective method of contraception from the time of giving informed consent until at least 16 weeks after the last dose of loncastuximab tesirine. Men with female partners who are of childbearing potential must agree that they will use a highly effective method of contraception from the time of giving informed consent until at least 16 weeks after the patient receives his last dose of loncastuximab tesirine

5. Active second primary malignancy other than non-melanoma skin
cancers, non-metastatic prostate cancer, in situ cervical cancer,
ductal or lobular carcinoma in situ of the breast, or other malignancy
that the Sponsor’s medical monitor and Investigator agree and
document should not be exclusionary
6. Autologous stem cell transplant within 30 days prior to start of study
drug (C1D1)
7. Allogeneic stem cell transplant within 60 days prior to start of study
drug (C1D1)
8. Active graft-versus-host disease
9. Post-transplant lymphoproliferative disorders
10. Active autoimmune disease, including motor neuropathy considered
of autoimmune origin and other central nervous system (CNS)
autoimmune disease
11. Known seropositive and requiring anti-viral therapy for human
immunodeficiency virus (HIV), hepatitis B virus (HBV), or
hepatitis C virus (HCV). Note: Testing is not mandatory to be
eligible
12. History of Stevens-Johnson syndrome or toxic epidermal necrolysis
13. Lymphoma with active CNS involvement at the time of screening,
including leptomeningeal disease
14. Clinically significant third space fluid accumulation
(i.e., ascites requiring drainage or pleural effusion that is either
requiring drainage or associated with shortness of breath)
15. Breastfeeding or pregnant
16. Significant medical comorbidities, including but not limited to,
uncontrolled hypertension (blood pressure [BP] =160/100 mmHg
repeatedly), unstable angina, congestive heart failure (greater than
New York Heart Association class II), electrocardiographic evidence
of acute ischemia, coronary angioplasty or myocardial infarction
within 6 months prior to screening, uncontrolled atrial or ventricular
cardiac arrhythmia, poorly controlled diabetes, or severe chronic
pulmonary disease
17. Major surgery, radiotherapy, chemotherapy, or other anti-neoplastic
therapy within 14 days prior to start of study drug (C1D1), except
shorter if approved by the Sponsor
18. Use of any other experimental medication within 14 days prior to
start of study drug (C1D1)
19. Planned live vaccine administration after starting study drug (C1D1)
20. Failure to recover to Grade =1 (Common Terminology Criteria for
Adverse Events [CTCAE] version 4.0) from acute non-hematologictoxicity toxicity (Grade =2 neuropathy or alopecia) due to previous therapy prior to screening
21. Congenital long QT syndrome or a corrected QTcF interval of
>480 ms at screening (unless secondary to pacemaker or bundle
branch block)
22. Any other significant medical illness, abnormality, or condition that
would, in the Investigator’s judgment, make the patient
inappropriate for study participation or put the patient at risk
