Screening laboratory values within the following parameters:~   1. Absolute neutrophil count (ANC) ≥1.0 × 103/µL (off growth factors at least 72 hours)~  2.

Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and GGT ≤2.5 × the upper limit of normal (ULN)~  5. Total bilirubin ≤1.5 × ULN (participants with known Gilbert's syndrome may have a total bilirubin up to ≤3 × ULN)~  6. Blood creatinine ≤1.5 × ULN or calculated creatinine clearance ≥60 mL/min by the Cockcroft-Gault equation~9. Negative beta-human chorionic gonadotropin (β-HCG) pregnancy test within 3 days prior to start of study drug on 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 study therapy. 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 study therapy~Exclusion Criteria:~1. Known history of hypersensitivity to or positive serum human ADA to a CD19 antibody.~2. Previous therapy with any checkpoint inhibitor~3. Autologous stem cell transplant within 100 days prior to start of study drug (C1D1)~4. History of allogenic stem cell transplant~5. History of solid organ transplant~6. Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease \[e.g., colitis or Crohn's disease\], diverticulitis \[with the exception of diverticulosis\], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome \[granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.\]). The following are exceptions to this criterion:~   1. Participants with vitiligo or alopecia~  2. Participants with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement~  3. Any chronic skin condition that does not require systemic therapy~  4. Participants without active disease in the last 5 years may be included but only after consultation with the Study Physician~  5. Participants with celiac disease controlled by diet alone~7. Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and tuberculosis testing in line with local practice)~8. Known seropositive and requiring anti-viral therapy for human immunodeficiency (HIV) virus, hepatitis B virus (HBV), or hepatitis C virus (HCV)~9. History of Stevens-Johnson syndrome or toxic epidermal necrolysis~10. Lymphoma with active central nervous system (CNS) involvement at the time of screening, including leptomeningeal disease~11. 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)~12. Breastfeeding or pregnant~13. 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~14. Radiotherapy, chemotherapy, or other anti-neoplastic therapy within 14 days prior to start of study drug (C1D1), except shorter if approved by the Sponsor.~15. Major surgery within 28 days prior to start of study drug (C1D1), except shorter if approved by the Sponsor. Note: Local surgery of isolated lesions for palliative intent is acceptable.~16. Use of any other experimental medication within 14 days prior to start of study drug (C1D1)~17. Planned live vaccine administration after starting study drug (C1D1)~18. Failure to recover to Grade ≤1 (Common Terminology Criteria for Adverse Events \[CTCAE\] version 4.0) from acute non-hematologic toxicity (Grade ≤2 neuropathy or alopecia) due to previous therapy prior to screening.~19. Congenital long QT syndrome or a corrected QTcF interval of \>470 ms at screening (unless secondary to pacemaker or bundle branch block)~20. History of another primary malignancy except for:~    1. Malignancy treated with curative intent and with no known active disease ≥5 years before the first dose of investigational product and of low potential risk for recurrence~   2. Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease~   3. Adequately treated carcinoma in situ without evidence of disease 21. History of active primary immunodeficiency~21. History of active primary immunodeficiency or any other significant medical illness, abnormality, or condition that would, in the Investigator's judgement, make the patient inappropriate for study participation or put the participant at risk.

Study Arms:
- ADCT-402 (Type: EXPERIMENTAL): Dose escalation phase: Ascending doses of Loncastuximab tesirine will be administered using a traditional 3+3 design. Dose level 1: 90 µg/kg, every 3 weeks (Q3W). Dose level 2: 120 µg/kg, Q3W. Dose level 3: 150 µg/kg, Q3W. Loncastuximab tesirine will be given for 2 doses, 3 weeks apart.~Dose expansion phase: Loncastuximab tesirine will be administered at the recommended dose determined in the dose escalation phase. Durvalumab will also be administered at a dose of 1500 mg once every 4 weeks (Q4W) throughout the dose escalation phase and dose expansion phase.

Based on this trial design, predict the completion outcome and termination type (if applicable).
