About this trial
This is a Phase 1b/2, multicenter, open-label, study of prizloncabtagene autoleucel (prizlo-cel), an autologous dual targeting chimeric antigen receptor (CAR) T-cell therapy targeting both cluster of differentiation (CD) CD20 and CD19, for the treatment of adult participants with relapsed or refractory (r/r) B-Cell non-Hodgkin lymphoma (B-NHL) or frontline high-risk diffuse large B-cell lymphoma (DLBCL).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Participant must be greater than or equal to (>=) 18 years of age, at the time of signing informed consent

Treatment groups
Trial outcomes
Primary outcomes
Phase 1b: Occurrence of Adverse Events (AEs) [Safety and Tolerability]
Occurrence of any AEs, including dose limiting toxicities (DLTs).
Phase 2: Overall Response (OR) As Assessed by Independent Review Committee (IRC)
Overall response is defined as a PR or CR at any point between the time of prizlo-cel infusion until PD or start of subsequent anti-lymphoma therapy, whichever occurs first (per Lugano 2014 guidelines).
Secondary outcomes
Phase 1b: Overall Response (OR)
Overall response is defined as a PR or CR at any point between the time of prizlo-cel infusion until PD or start of subsequent anti-lymphoma therapy, whichever occurs first (per Lugano 2014 guidelines).
Phase 1b: Duration of Response (DOR)
DOR is defined as the time from the first documented CR or PR after prizlo-cel infusion until PD or death, whichever occurs first (per Lugano 2014 guidelines).
Phase 1b: Pharmacokinetic Evaluation of Prizlo-Cel
Prizlo-cel blood levels will be reported.
Phase 2: Occurrence of Adverse Events (AEs) by Severity
Severity of AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 as follows: Grade 1 (Mild), Grade 2 (Moderate), Grade 3 (Severe), Grade 4 (Life-threatening ), Grade 5 (Death). Cytokine release syndrome (CRS), Immune effector cell-associated neurotoxicity syndrome (ICANS), and Immune effector cell-associated hemophagocytic lymphohistiocytosis-like syndrome (IEC-HS) will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) consensus grading.
