Number of Participants With Adverse Events in Cohort 7

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.

Number of Participants With Serious Adverse Events (SAEs) in Cohort 7

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.

Progression Free Survival (PFS) Using European Medicines Agency (EMA) Criteria

Progression-free survival is defined as the interval from the date of JCAR017 infusion to progressive disease or death due to any cause, whichever occurred first. Per European Medicines Agency (EMA) criteria, participants who did not experience progressive disease and who did not die before the data cutoff date were censored at the time of the last visit with adequate response assessment when the participants were known not to have progressed.

Estimated using Kaplan-Meier product-limit estimates.

Overall Survival (OS)

Overall survival is defined as the interval from the date of JCAR017 infusion to the date of death due to any reason. Data from surviving participants was censored at the last time that the participant was known to be alive.

Estimated using Kaplan-Meier product-limit estimates.

Duration of Response (DOR)

DOR is from first response (complete response (CR), CR unconfirmed (CRu) or partial response (PR)) to progression (PD) or death. Those without PD or death were censored at the last assessment.

Maximum Concentration (Cmax) of JCAR017 by qPCR

Cmax is the maximum or peak concentration of drug reached in the plasma following a dose of the drug.

Quantitative polymerase chain reaction (qPCR) was used to determine Cmax by detecting the JCAR017 transgene.

Baseline is defined as the last available recorded value on or prior to the date of JCAR017 infusion.

Time to Peak Concentration (Tmax) of JCAR017 by qPCR

Time to maximum concentration (Tmax) is the time it takes for a drug to reach the maximum concentration (Cmax) after administration.

Quantitative polymerase chain reaction (qPCR) was used to determine Tmax by detecting the JCAR017 transgene.

Baseline is defined as the last available recorded value on or prior to the date of JCAR017 infusion.

Total Exposure to JCAR017 as Measured by Area Under the Curve (AUC) of JCAR017 by qPCR

Area Under the Curve (AUC) represents the total exposure of participants to study drug.

Quantitative polymerase chain reaction (qPCR) was used to determine AUC by detecting the JCAR017 transgene.

Baseline is defined as the last available recorded value on or prior to the date of JCAR017 infusion.

Percent of Participants With Presence of JCAR017 Transgene in Peripheral Blood by qPCR

Persistence is defined as a transgene count greater than or equal to the lower limit of detection (LLOD) of 5 copies per reaction. Data obtained after the start of a new anti-cancer therapy were excluded. qPCR = Quantitative polymerase chain reaction.

Change From Baseline in European Organisation for Research and Treatment of Cancer - Quality of Life C30 Questionnaire (EORTC QLQ-C30) Scores

The EORTC QLQ-C30 consists of five functional scales (physical, role, emotional, cognitive, social), three symptom scales (fatigue, nausea/vomiting, pain), a global health status/health-related quality of life (HRQoL) scale, and six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties). The questionnaire is scored on a 4-point Likert scale: 1 = not at all, 2 = a little, 3 = quite a bit, 4 = very much. The raw score is the average of the items contributing to the scale. The final scores are calculated via linear transformation of raw scores and range from 0 to 100. For functional scales higher scores indicate better QoL. For symptom scales and single items lower scores indicate fewer symptoms, i.e. better QoL. Baseline the last available recorded scores on or prior to the date of JCAR017 infusion. Only global health, fatigue, physical and cognitive functioning subscales were assessed.

Change From Baseline in Functional Assessment of Cancer Treatment-Lymphoma "Additional Concerns" Subscale (FACT-LymS) Scores

The Functional Assessment of Cancer Treatment-Lymphoma "Additional concerns" subscale (FACT-LymS) consists of the FACT-General scale and a 15-item lymphoma-specific additional concerns subscale (LYM). This scale addresses symptoms and functional limitations that are important to lymphoma patients. Only the LYM subscale was administered in this study. The LYM items are scored on a 0 ("Not at all") to 4 ("Very much") response scale. Items are aggregated to a single score on a 0-60 scale. Lower scores indicate better health outcomes. Baseline the last available recorded scores on or prior to the date of JCAR017 infusion.
