Brief Summary:

The purpose of this study is to evaluate the safety, tolerability, dose-limiting toxicities (any harmful effect of a drug) (DLT), maximum tolerated dose (MTD), recommended Phase 2 dose (RP2D) and preliminary clinical activity of duvortuxizumab when administered intravenously to participants with relapsed or refractory B-cell malignancies [diffuse-large B cell lymphoma (DLBCL), follicular lymphoma (FL), mantle-cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), and acute lymphoblastic leukemia (ALL)].

Condition or disease	Intervention/treatment	Phase
Leukemia, Lymphocytic, Chronic, B-Cell; Lymphoma, Large B-Cell, Diffuse; Lymphoma, Follicular; Lymphoma, Mantle-Cell; Precursor Cell Lymphoblastic Leukemia-Lymphoma	Drug: Part 1 (Dose Escalation): Duvortuxizumab; Drug: Part 2 (Dose Expansion): Duvortuxizumab	Phase 1

Detailed Description:

This first in human study consists of 2 parts: a) The dose escalation part and b) The dose expansion part. This is an openlabel (all participants know the identity of the intervention), multicenter (more than one study site) study to evaluate the safety, establish a recommended Phase 2 dose (RP2D), and to determine the preliminary efficacy of duvortuxizumab in participants with relapsed or refractory B cell malignancies. The dose escalation part of the trial (Part 1) will be comprised of 3 different patient groups based on disease indication: Group 1 (DLBCL, FL, MCL); Group 2 (CLL); Group 3 (ALL). The duvortuxizumab dosing will be done on biweekly and weekly basis. Duvortuxizumab weekly escalating dosing will be investigated. Dose escalation will begin with Group 1 and will initially follow an accelerated dose titration design, followed by a traditional 3+3 design. At each dose escalation level the treatment of the second participant should be initiated after at least 72 hours of observation after the start of the first duvortuxizumab dose of the first participant. Dose escalation in Groups 2 and 3 will follow a 3+3 design and will begin after the initial dose level in Group 1 is deemed safe. Participants [Group 1 (DLBCL, FL, MCL), Group 2 (CLL) Group 3 (ALL)] are enrolled into cohorts of increasing dose levels of duvortuxizumab administered in 28 day treatment cycles. Up to 3 RP2Ds may be determined in Part 1 (one RP2D for Group 1, one RP2D for Group 2, and one RP2D for Group 3). In the cohort expansion part of the trial (Part 2), participants with relapsed or refractory B cell malignancies (DLBCL, FL, MCL, CLL and ALL) will be enrolled according to tumor type in up to 5 cohorts and receive duvortuxizumab at the RP2D determined in Part 1 for their disease type. The study consists of 3 periods: Screening period (up to 28 days prior to the first dose of study drug); Treatment period [first dose of study drug until the End of Treatment Visit (within 30 days after the last dose)]; and follow up period [End of Treatment Visit and continue until death, lost to follow up, consent withdrawal, or study end (as determined by the sponsor), whichever occurs first]. Number of participants who achieve an overall response in each Dose Expansion cohort will be evaluated primarily. Participants' safety will be monitored throughout the study.

Arm	Intervention/treatment
Experimental: Dose Escalation: Participants With Certain B-Cell Malignancies; During accelerated dose titration in Group 1, participant will receive duvortuxizumab starting at 0.5 nanogram per kilogram (ng/kg) for biweekly dosing. Dose will be increased by half logarithmic steps in subsequent Dose Level (DL). After safety stopping criteria are met, Dose Escalation (DE) in Group 1 will transition to 3+3 design, and will continue until the Maximum tolerated Dose (MTD) is defined. DE in Groups 2 and 3 will follow 3+3 design, begin after initial dose level in Group 1 is deemed safe and recommended phase 2 doses (RP2D) for Part 1 of study can be decided. Duvortuxizumab at a starting dose of 50 ng/kg weekly will also be investigated in Group 1 and will follow 3+3 study design continue until the MTD or Maximum administered dose (MAD) is reached. Disease-specific dose escalation in Group 2 and 3 will not be initiated until dose in Group 1 is determined safe.	Drug: Part 1 (Dose Escalation): Duvortuxizumab; Participants currently enrolled in the study will continue to receive duvortuxizumab every 14 days (biweekly dosing) in each 28 ‑day cycle as an intravenous infusion.
