This is a multicenter phase 1, open-label trial that will evaluate the safety and tolerability of loncastuximab tesirine in combination with DA-EPOCH-R.
Phase 1a will involve a standard 3+3 dose escalation design to find the maximum tolerated dose (MTD) and/or recommended dose for expansion. The MTD will be determined based on the results of the safety evaluation. No intra-patient dose escalation is allowed.
Phase 1b will involve a cohort expansion at the dose level determined to be the recommended phase 2 dose.

Experimental: Loncastuximab Tesirine Dose Escalation 0.075 mg/kg by IV.
The study uses a classic 3+3 dose-escalation design. Three patients will be enrolled into a cohort receiving 0.075 mg/kg by IV. If there is no dose-limiting toxicity (DLT) seen in any of these participants, the trial will enroll additional participants into the next higher dose cohort, which is 0.12 mg/kg by IV. If one patient experiences a DLT at a specific dose, an additional three individuals will be accrued into that same dose cohort. The third dose level is 0.15 mg/kg by IV. DLTs in two or more at a specific dose level indicates that the MTD has been exceeded; dose escalation will not be pursued, and the prior dose level will be expanded to six patients; if there is no more than one patient who experiences a DLT among those six patients, that dose level is considered the MTD.

- The maximum tolerated dose (MTD). [ Time Frame: Up to 21 days (one cycle) for each dosing cohort. ]MTD is defined as the highest dose level where zero of the first three patients treated or ≤1 of the first six patients treated had a dose-limiting toxicity (DLT) during cycle 1 of phase 1a.
- The number of dose-limiting toxicities (dose-escalation phase only). [ Time Frame: Up to 21 days (one cycle). ]A dose-limiting toxicity is defined as any of the following within 21 days after administration of the first dose of loncastuximab tesirine in phase 1a part 1a only (except any toxicity clearly due to disease or other causes): adverse events and lab data, using Common Terminology Criteria for Adverse Events (CTCAE) v.5.0.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:

- Patients must not have received prior multiagent chemotherapy for their lymphoma. Limited palliative radiation is allowed. Corticosteroid therapy in symptomatic patients will be permitted and does not require a washout period. Prephase treatment with cyclophosphamide and corticosteroids or vincristine and corticosteroids is allowed in symptomatic patients.
- Eastern Cooperative Oncology Group (ECOG) Performance Status criteria of 0-3 (see Appendix 1).
-
Adequate hematological function, defined as absolute neutrophil count (ANC) ≥1 × 103/μL and platelet count ≥50 x 10^3/μL.
- These requirements do not apply to patients with bone marrow involvement of lymphoma.
-
Adequate hepatic function: aspartate aminotransferase (AST) / alanine aminotransferase (ALT) / gamma-glutamyl transferase (GGT) ≤ 3 x institutional upper limit of normal (ULN) and bilirubin < 1.5 x ULN, unless due to hepatic involvement with lymphoma or Gilbert's syndrome.
- Exceptions can be granted from principal investigator for primarily indirect bilirubinemia if due to recent transfusion and/or hemolysis.
- estimated glomerular filtration rate (eGFR) ≥ 30 ml/min/1.73sqm.
- Left ventricular ejection fraction (LVEF) of ≥50%, assessed by echocardiography or cardiac multi-gated acquisition (MUGA) scan.
- Patients with marrow-only disease will be eligible.
- Patients rendered no evidence of disease via surgery will be eligible.
- Central nervous system (CNS) involvement is not considered contraindication for patients with Burkitt lymphoma.
- Known HIV-positive patients compliant with antiretroviral therapy and with undetectable viral loads will be permitted.
-
Pregnancy It is not known what effects this treatment has on human pregnancy or development of the embryo or fetus. Therefore, female patients participating in this study should avoid becoming pregnant, and male patients should avoid impregnating a female partner. Non-sterilized female patients of reproductive age and male patients should use effective methods of contraception through defined periods during and after study treatment as specified below.
- Female patients of childbearing potential must use a highly effective method of contraception during the entire study treatment period and through nine months after the last dose of loncastuximab tesirine.
- Male patients, even if surgically sterilized (i.e., status postvasectomy), with female partners who are of childbearing potential should use a condom when sexually active during the entire study treatment period and through six months after the last dose of loncastuximab tesirine.
- Ability to understand a written informed consent document, and the willingness to sign it.
