Prior therapy must have included: - Anti-CD20 monoclonal antibody, and - An anthracycline containing chemotherapy regimen - Participants with tFL must have received at least one of their prior lines of therapy after transformation to DLBCL 4b. Cohort 5 (High-risk first-line) participants must have high-risk large B-cell lymphoma 5. Relapsed or refractory disease, defined by the following: - Disease progression after last regimen (including salvage therapy after autologous stem cell transplantation [ASCT]). In participants who have only received front-line therapy, progression should be ≤ 12 months of first-line therapy (applicable for Cohort 3) - In patients who received one line of therapy, refractory disease is defined as failure to achieve at least a PR after at least 4 cycles of therapy (applicable for Cohort 3) - In patients who received two or more lines of therapy (Cohorts 1, 2, and 4), refractory disease is defined as failure to achieve a CR to last line of therapy (including CAR T and/or salvage therapy). 6. At least 1 measurable lesion (per Lugano classification). Lesions that have been previously irradiated will be considered measurable only if progression has been documented following completion of radiation therapy 7.

Participants who have received therapy for a prior malignancy within the prior 3 years, e.g., in the adjuvant setting, are not excluded 2. Active central nervous system (CNS) involvement by malignancy on magnetic resonance imaging (MRI) or by lumbar puncture. Participants with prior evidence of brain metastasis treated at least 8 weeks prior to enrollment will not be excluded for participation if CNS disease is deemed stable at the time of study enrollment 3.

Detailed Description

This is a Phase 1/2, multi-center, open-label study evaluating the safety and efficacy of LYL314, a dual-targeting chimeric antigen receptor (CAR) targeting cluster of differentiation (CD)19 and CD20 in participants with aggressive large B-cell lymphoma. Five cohorts of participants will be enrolled: Cohort 1: Participants who have not received a prior CAR T-cell product (CAR T naïve) and have received at least two or more prior lines of treatment (third-line or later). Cohort 2: Participants who have received a prior CAR T-cell product (CAR T experienced) and have received at least two or more prior lines of treatment including one CAR T-cell therapy. Cohort 3: Participants with refractory disease or relapse within one year of first-line therapy (second-line). Cohort 4: Participants who have received prior T-cell engager (TCE) therapy and have received at least two or more prior lines of treatment including one TCE therapy. Cohort 5: Participants receiving first-line treatment for high-risk large B-cell lymphoma who remain with disease on positron emission tomography scanning (PET-positive) after 2 to 3 cycles of standard-of-care chemoimmunotherapy (high-risk first-line). Up to approximately 150 participants (across all cohorts) will be enrolled in the dose finding Phase 1 part of the study. The Phase 2 pivotal study (PiNACLE) will expand enrollment of Cohort 1 to approximately 120 participants to further evaluate the safety and efficacy of LYL314. LYL314 treatment consists of a single administration of CAR transduced autologous T-cells administered intravenously after a conditioning chemotherapy regimen consisting of fludarabine and cyclophosphamide, administered over 3 days. Individual participants will remain in the active post-treatment follow-up (PTFU) period for approximately 2 years. Participants will continue in long-term follow-up (LTFU) for 15 years from LYL314 treatment.
