Study of LYL314 in Aggressive Large B-Cell Lymphoma

Exclusion Criteria19

• History of malignancy other than non-melanoma skin cancer or carcinoma in situ (e.g., cervix, bladder, breast) unless disease-free for at least 3 years. Participants who have received therapy for a prior malignancy within the prior 3 years, e.g., in the adjuvant setting, are not excluded
• 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
• History of cardiac lymphoma involvement or Epstein-Barr virus (EBV)+ lymphoma
• Ongoing or impending oncologic emergency (e.g., tumor mass effect, tumor lysis syndrome, known vascular invasion)
• Received the following therapies in the specified time frame prior to enrollment/leukapheresis
• Any systemic therapy within 2 weeks
• Any systemic inhibitory/stimulatory immune checkpoint molecule therapy within 3 half-lives prior to enrollment (e.g., ipilimumab, nivolumab, pembrolizumab, atezolizumab, OX40 agonists, 4-1BB agonists)
• Fludarabine within 12 weeks
• Alemtuzumab, bendamustine or antithymocyte globuline (ATG) within 6 months
• Any T cell engager/bispecific antibody therapy such as CD20/CD3 or CD19/CD3 bispecific antibodies within 4 weeks
• Any experimental therapy within 4 weeks or 5 half-lives (whichever is shorter)
• Received radiation therapy within 3 weeks prior to enrollment/leukapheresis
• Experiencing non-hematologic toxicities due to prior therapy. Exceptions include: stable and recovered to grade ≤ 1 or non-clinically significant toxicities such as (1) alopecia, (2) toxicities where Grade 2 is solely defined by participant receiving hormone replacement therapy for endocrinopathies resulting from previous checkpoint inhibitor therapy, (3) Grade 2 lymphopenia, and (4) hearing loss or Grade 2 neuropathy associated with prior treatment with taxanes or platinating agents
• History of allogeneic stem cell or solid organ transplantation
• Receipt of autologous stem cell transplantation within 6 weeks prior to enrollment/leukapheresis
• History of prior genetically modified cell therapy other than a product targeting CD19 with an FMC63-based CAR (e.g., axicabtagene ciloleucel (axi-cel), tisagenlecleucel (tisa-cel), or lisocabtagene maraleucel (liso-cel). For all other CAR T cell therapy treatments, discussion with the Sponsor's Medical Monitor is required
• Primary immunodeficiency
• History of autoimmune disease (e.g., Crohn's disease, rheumatoid arthritis, systemic lupus) resulting in end organ injury or requiring systemic immunosuppression/systemic disease modifying agents within the last 2 years. Participants who have other autoimmune condition(s) considered to be associated with underlying malignancy may be enrolled in the study after discussion with and approval of the Medical Monitor.
• Other protocol-defined criteria apply.
