Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Patients undergo leukapheresis and lymphodepleting chemotherapy between days -5 to -3 prior to treatment and receive liso-cel intravenously (IV) on day 0. Patients then receive ST-067 subcutaneously (SC) weekly on days 14, 21, and 28 or days 10, 17, and 24. Patients may continue to receive maintenance ST-067 SC at day 35 once weekly. Treatment continues for up to 8 doses in the absence of disease progression or unacceptable toxicity. Patients undergo x-ray imaging, and echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening. Patients also undergo computed tomography (CT) and/or positron emission tomography (PET) as well as lumbar puncture for cerebral spinal fluid (CSF) collection and bone marrow aspiration and biopsy as clinically indicated during screening and follow-up. Patients undergo blood sample collection throughout the study.
After completion of study treatment, patients are followed up at 3, 6, 9, and 12 months after CAR T-cell infusion, then will be followed per standard of care long-term follow-up until the patient dies, is lost to follow-up, or withdraws consent.

Treatment (liso-cel, ST-067)
Patients undergo leukapheresis and lymphodepleting chemotherapy between days -5 to -3 prior to treatment and receive liso-cel IV on day 0. Patients then receive ST-067 SC weekly on days 14, 21, and 28 or days 10, 17, and 24. Patients may continue to receive maintenance ST-067 SC at day 35 once weekly. Treatment continues for up to 8 doses in the absence of disease progression or unacceptable toxicity. Patients undergo x-ray imaging, and ECHO or MUGA during screening. Patients also undergo CT and/or PET as well as lumbar puncture for CSF collection and bone marrow aspiration and biopsy as clinically indicated during screening and follow-up. Patients undergo blood sample collection throughout the study.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients with LBCL (including diffuse large B-cell lymphoma \[DLBCL\] not otherwise specified \[including DLBCL arising from indolent lymphoma\], high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, and follicular lymphoma grade 3B) with at least 2 lines of systemic therapy and an Food and Drug Administration (FDA)-approved indication for treatment with liso-cel
* Fluorodeoxyglucose (FDG)-avid disease on PET imaging before lymphodepletion or pathology evidence of active disease
* Evidence of CD19 expression on any prior or current tumor specimen or a high likelihood of CD19 expression based on disease histology
* Karnofsky performance status \>= 60%
* Adequate bone marrow function for lymphodepletion chemotherapy defined as: absolute neutrophil count (ANC) \>= 1000 cells/mm\^3, platelets \>= 50,000 cells/mm\^3, and hemoglobin \>= 8 g/dL, unless the cytopenias are due to bone marrow involvement by lymphoma in the opinion of the principal investigator (PI)
* Calculated creatinine clearance (Cockcroft/Gault) \> 30 mL/min/1.73 m\^2
* Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =\< 3 x upper limit of normal (ULN) (or \< 5 x ULN for subjects with lymphomatous infiltration of the liver) and total bilirubin =\< 2 (or \< 3.0 for subjects with Gilbert's syndrome, lymphomatous infiltration of the liver, or hemolysis)
* Adequate pulmonary function based on pulmonary function testing (PFT), defined as forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) ratio of \>= 60% of predicted value and diffusing capacity of the lung for carbon monoxide (DLCO; corrected) \>= 40% of predicted value
* Adequate cardiac function, defined as left ventricular ejection fraction (LVEF) \>= 40% as assessed by echocardiogram or multiple uptake gated acquisition (MUGA)
* Women of reproductive potential (defined as all women physiologically capable of becoming pregnant) must agree to use suitable methods of contraception for at least 30 days after the last dose of study therapy (ST-067)
* Males who have partners of reproductive potential must agree to use an effective barrier contraceptive method for at least 90 days after the last dose of study therapy (ST-067)
