The complete response rate (CRR) is defined as the proportion of subjects achieving an objective response of complete response prior to start of another non-study anticancer therapy. CRR is based on the best overall response post-lisocabtagene maraleucel infusion. CRR will be defined according to the Lugano Classification.

Overall response rate (ORR) determined by Investigator assessment after JCAR017 infusion. The ORR is the percent of participants with best overall response (BOR) of either complete response (CR), complete response unconfirmed (Cru) or partial response (PR). Complete response (CR): * Brain imaging: No contrast enhancement * Corticosteroid dose: None * Eye examination: Normal * Cerebrospinal fluid cytology: Negative Complete response unconfirmed (CRu): * Brain imaging: No contrast enhancement, Minimal abnormality * Corticosteroid dose: Any * Eye examination: Normal, minor RPE abnormality * Cerebrospinal fluid cytology: Negative Partial response (PR): * Brain imaging: 50% decrease in enhancing tumor, no contrast enhancement. * Corticosteroid dose: Irrelevant * Eye examination: Minor RPE abnormality, decrease in vitreous cells or retinal infiltrate. * Cerebrospinal fluid cytology: Negative, persistent or suspicious

An adverse event (AE) is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a participant during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the participant's health, including laboratory test values, regardless of etiology. Any worsening (i.e., any clinically significant adverse change in the frequency or intensity of a preexisting condition) should be considered an AE. Graded according to NCI CTCAE (Version 4.03) guidelines where grade 1 = mild, grade 2 = moderate, grade 3 = severe, grade 4 = life threatening, grade 5 = death.

A serious adverse event (SAE) is defined as any adverse event (AE) occurring at any dose that: * Results in death; * Is life-threatening (ie, in the opinion of the Investigator, the participant is at immediate risk of death from the AE); * Requires inpatient hospitalization or prolongation of existing hospitalization (hospitalization is defined as an inpatient admission, regardless of length of stay). * Results in persistent or significant disability/incapacity (a substantial disruption of the participant's ability to conduct normal life functions); * Is a congenital anomaly/birth defect; * Constitutes an important medical event. Graded according to NCI CTCAE (Version 4.03) guidelines where grade 1 = mild, grade 2 = moderate, grade 3 = severe, grade 4 = life threatening, grade 5 = death.

JCAR017 treatment-emergent laboratory abnormalities are defined as an abnormality that, compared to baseline, worsens by at least one grade after JCAR017 infusion. The baseline value is defined as the last available recorded value on or prior to the date of JCAR017 infusion. Grade 1 (Mild), Grade 2 (Moderate), Grade 3 (Severe), Grade 4 (Life-threatening), Grade 5 (Death).

JCAR017 treatment-emergent laboratory abnormalities are defined as an abnormality that, compared to baseline, worsens by at least one grade after JCAR017 infusion.

The percentage of subjects who receive a chimeric antigen receptor (CAR) T-cell infusion after receiving bridging radiation therapy. A one-sided Binomial test will be conducted to assess whether acceptable percentage (\>70% vs \<70%) of patients receive CAR T-cell perfusion after undergoing the radiation therapy.

Participants enrolled in Phase 1 are considered evaluable for DLTs if they received an infusion of conforming JCAR017 cell product and at least one dose of the combination agent and completed the specified DLT evaluation period or if they have received an infusion of conforming JCAR017 cell product and at least one dose of the combination agent and experience a DLT during the DLT evaluation period.

Percentage of participants achieving a complete response (CR). CR is complete radiologic response (CRR) and complete metabolic response (CMR). CR was measured using CT and PET and assessed for the presence of index and non-index lesions, spleen size, and the absence of new lesions or diseased bone marrow. To be considered as having CRR participants had to have all of the following: * Index lesions - longest transverse diameter of nodal lesions ≤ 1.5 cm and the absence of extranodal disease. * Non-index lesions - the absence of non-index lesions. * Spleen size \<13 cm * The absence of new lesions * Normal bone marrow assessment To be considered as having CMR participants had to have all of the following: * A score of 1, 2, or 3 with or without residual mass on 5-PS for index and non-index lesions. * The absence of new lesions * No evidence of FDG-avid disease in marrow and a normal bone marrow assessment
