Axicabtagene Ciloleucel for the Treatment of Relapsed/Refractory Primary or Secondary Central Nervous System Lymphoma
This phase I trial studies the side effects of axicabtagene ciloleucel (axi-cel) in treating patients with primary or secondary central nervous system lymphoma that has come back (relapsed) or has not responded to treatment (refractory). Axi-cel is a chimeric antigen receptor (CAR) T-cell therapy that is manufactured using a patient's own white blood cells. A virus is used to introduce a gene that creates a protein (called a CAR) on the surface of T cells, a type of blood cell that fights infection and can eliminates cancer cells. With axi-cel, the CAR on the T cells may bind to and kill cells that express CD19, a molecule that may be found on B-cell lymphomas. This purpose of this trial is to test the effect and safety of axi-cel in treating patients with primary or secondary central nervous system lymphoma, and to better understand what causes neurological toxicity following treatment with axi-cel.

PRIMARY OBJECTIVE:
I. To evaluate the safety of axi-cel in patients with relapsed/refractory (R/R) primary or secondary central nervous system lymphoma (CNSL) without active systemic lymphoma as measured by the rate of treatment limiting toxicities (TLTs) and the rate of grade 3+ adverse events (AEs) regardless of attribution.
SECONDARY OBJECTIVES:
I. To evaluate the overall safety profile of axi-cel in patients with R/R primary or secondary CNSL with or without active systemic lymphoma.
II. To evaluate the efficacy of axi-cel in patients with R/R primary or secondary CNSL with or without active systemic lymphoma as measured by:
IIa. Objective response rate (ORR); complete response (CR) rate; duration of response (DOR); progression-free survival (PFS); overall survival (OS).
EXPLORATORY OBJECTIVES:
I. Correlative analyses of cerebrospinal fluid (CSF) and serum biomarkers of efficacy and toxicity.
Ia. Correlation of serial serum and CSF levels of axi-cel and cytokines with toxicity and efficacy.
Ib. Correlation of serial peripheral blood and CSF immune cell subsets by mass cytometry (CyTOF), conventional flow cytometry and single cell ribonucleic acid sequencing (RNAseq) with toxicity and efficacy.
Ic. Evaluation of peripheral blood and CSF by genomic analysis for recurrent mutations, structural rearrangements and copy number alterations associated with CNSL, and correlation of circulating tumor DNA (ctDNA) with response or resistance.
Id. Correlation of apparent diffusion coefficient (ADC)/diffusion weighted imaging (DWI)/perfusion magnetic resonance (MR) imaging to clinical response.
OUTLINE:
Patients receive cyclophosphamide intravenously (IV) over 60 minutes and fludarabine phosphate IV over 30 minutes daily on days -5 to -3. Patients then receive axicabtagene ciloleucel IV on day 0.
After completion of study treatment, patients are followed up every 3 months for 24 months, annually for years 2-5, and then periodically for 15 years.
