Clinical Trial Summary

This phase 2 trial studies the side effects and best dose of tazemetostat and zanubrutinib in combination with tafasitamab and lenalidomide, and to see how well these combinations work in treating patients with large B-cell lymphoma that returned or did not respond to earlier treatment. Tazemetostat is in a class of medications called EZH2 inhibitors. It helps to stop the spread of cancer cells. Zanubrutinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells. tafasitamab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Lenalidomide is in a class of medications called immunomodulatory agents. It works by helping the bone marrow to produce normal blood cells and by killing abnormal cells in the bone marrow. The addition of tazemetostat or zanubrutinib to tafasitamab and lenalidomide may be able to shrink the cancer or extend the time without cancer symptoms coming back.

Description:

PRIMARY OBJECTIVES: I. To determine the recommended phase II dose of tafasitamab + lenalidomide + tazemetostat AND of tafasitamab + lenalidomide + zanubrutinib. (Safety Run-in) II. To compare progression-free survival (PFS) of patients with relapsed/refractory large B-cell lymphoma (R/R LBCL) treated with tafasitamab + lenalidomide + tazemetostat vs control (tafasitamab + lenalidomide) AND treated with tafasitamab + lenalidomide + zanubrutinib versus (vs) control. (Randomized Phase II Study) SECONDARY OBJECTIVES: I. To estimate the hazard ratio for PFS for control vs. tafasitamab + lenalidomide + tazemetostat in germinal center B-cell (GCB) and non-GCB (activated B-cell [ABC]/unclassified) subsets. II. To estimate the hazard ratio for PFS for control vs. tafasitamab + lenalidomide + zanubrutinib in GCB and non-GCB (ABC/unclassified) subsets. III. To estimate progression-free survival (PFS), overall response rate (ORR), complete response rate (CR), partial response rate (PR), duration of response (DOR), event-free survival (EFS), overall survival (OS), in GCB and non-GCB LBCL for each treatment. IV. To evaluate adverse events within each treatment arm. OTHER OBJECTIVES: I. To explore PFS within subgroups defined by molecular profile (e.g., MCD, BN2, N1 and EZB) and genetic subtypes. II. To explore PFS in the tafasitamab-lenalidomide control arm vs that in matched historical control from L-MIND and realMIND studies. III. To assess frailty (Cumulative Illness Rating Scale [CIRS] and Timed Get Up and Go [TUG]) and its correlation with outcome. PRIMARY PATIENT-REPORTED OUTCOMES OBJECTIVE: I. To compare patient-reported lymphoma-specific symptoms as measured by the Functional Assessment of Cancer Therapy-Lymphoma (FACT-Lym) Trial Outcome Index sub-scale at 3 months after randomization between the control arm and each experimental arm (Arm 1 versus Arm 2 and Arm 3 versus Arm 2). SECONDARY PATIENT-REPORTED OUTCOMES OBJECTIVE: I. To compare participant-reported toxicity (treatment side effect) symptoms using selected Patient Reported Outcomes-Common Terminology Criteria for Adverse Events (PRO-CTCAE) items between experimental vs control arms. EXPLORATORY PATIENT-REPORTED OUTCOMES OBJECTIVES: I. To compare patient-reported quality of life using the FACT-General (G) subscale score and the FACT-Lym total score at 3 months after randomization between the control arm and each experimental arm. II. To compare quality of life over time between treatment arms from baseline to 12 months after randomization as measured by the FACT-Lym trial outcome index (TOI), FACT-G, and FACT-Lym total score using longitudinal analysis. BANKING OBJECTIVE: I. To bank specimens for future correlative studies. OUTLINE: This is a dose-escalation study of tazemetostat and zanubrutinib. PART I (SAFETY RUN-IN): Patients are assigned to 1 of 2 arms per treating investigator's choice. ARM I: Patients receive tafasitamab intravenously (IV), lenalidomide orally (PO), and tazemetostat PO on study.

Primary	Progression-free survival (PFS)	Will be compared between participants randomized to control Arm 2 (tafasitamab + lenalidomide) versus (vs) experimental Arm 1 (tafasitamab + lenalidomide + tazemetostat), AND control Arm 2 vs experimental Arm 3 (tafasitamab + lenalidomide + zanubrutinib), respectively.	From date of randomization to date of first observation of progressive disease according to the 2014 Lugano classification, or death due to any cause, assessed up to 3 years
Primary	Trial Outcome Index (TOI) score from the Functional Assessment of Cancer Therapy-Lymphoma (FACT-Lym) (Patient Reported Outcome [PRO] Study)	Will compare the trial outcome index (TOI) score between each experimental arm (Arm 1 and Arm 3) to the control arm (Arm 2). The TOI score is composed of the Physical Well-Being, Functional Well-Being, and lymphoma-specific subscale scores. The scores range from 0-116, with higher scores indicating a higher quality of life.	Baseline up to 3 months after randomization
Secondary	Hazard ratio for PFS in the germinal center B-cell (GCB) subgroup	Will calculate the 80% confidence interval (CI) for the Cox regression time-to-event estimate of the hazard ratio associated with addition of tazemetostat to tafasitamab+lenalidomide combination (Arm 2 vs Arm 1) in the GCB subgroup. If the confidence interval excludes 1, then 80% CI will be calculated for the non-GCB group.	Up to 3 years
Secondary	Hazard ratio for PFS in the non-GCB subgroup	Will calculate the 80% CI for the hazard ratio associated with addition of zanubrutinib to tafasitamab+lenalidomide combination (Arm 2 vs Arm 3) in the non-GCB subgroup. If the confidence interval excludes 1, then 80% CI will be calculated for the GCB group.	Up to 3 years
Secondary	PFS	Will estimate in GCB and non-GCB large B-cell lymphoma (LBCL) for each treatment. Will be estimated using the method of Kaplan-Meier and 80% confidence interval will be calculated.
