What was measured

Objective response rate is the proportion of subjects in the efficacy-evaluable set with radiologically confirmed measurable disease at baseline, who achieved partial response (PR) or better after infusion as determined by RECIST 1.1. Missing or non-evaluable time points will not be included. Per RECIST 1.1, a complete response is defined as "disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm." A partial response is defined as "at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters."

Analysis population: Cohort 4 was permanently closed.

Groups in this outcome

Cohort 1

Single dose of 1-3x10\^7 huCARTmeso cells/m\^2 huCART-meso cells: Intravenous administration or local delivery of lentiviral transduced huCART-meso cells in 7 cohorts with or without lymphodepletion..

Cohort 2

Cyclophosphamide 1 gram/m\^2 administered 2-4 days prior to a single dose of 1-3x10\^7 huCARTmeso cells/m\^2 huCART-meso cells: Intravenous administration or local delivery of lentiviral transduced huCART-meso cells in 7 cohorts with or without lymphodepletion..

Cohort 3

PERMANENTLY CLOSED huCART-meso cells: Intravenous administration or local delivery of lentiviral transduced huCART-meso cells in 7 cohorts with or without lymphodepletion..

Cohort 4

PERMANENTLY CLOSED huCART-meso cells: Intravenous administration or local delivery of lentiviral transduced huCART-meso cells in 7 cohorts with or without lymphodepletion..

Cohort 5

Single dose of 1-3x10\^7 huCART-meso cells/m\^2 day 0 by intrapleural infusion (IP) through an indwelling pleural catheter without any conditioning chemotherapeutic regimen. huCART-meso cells: Intravenous administration or local delivery of lentiviral transduced huCART-meso cells in 7 cohorts with or without lymphodepletion..

Cohort 6

Cyclophosphamide 1 gram/m\^2 administered 2-4 days prior to dose of 1-3x10\^7 huCART-meso cells/m\^2 via IV infusion on Day 0. This initial infusion may be followed by up to two additional IV infusions of huCART-meso cells at the same dose level, given approximately 21-42 days apart, if the subject meets eligibility to receive additional infusions. Cyclophosphamide will not be repeated prior to subsequent doses of huCART-meso cells. huCART-meso cells: Intravenous administration or local delivery of lentiviral transduced huCART-meso cells in 7 cohorts with or without lymphodepletion..

Cohort 7

Cyclophosphamide 300 mg/m\^2/day and fludarabine 30 mg/m\^2/day given over 3 days by IV infusion followed by a single dose of 1-3x10\^7 huCART-meso cells/m\^2 via intraperitoneal (i.p.) administration. Lymphodepleting chemotherapy will be scheduled such that the last day of chemotherapy is 3 days (+/- 1 day) prior to the infusion of huCART-meso cells. This initial i.p. infusion may be followed by up to two additional infusions of huCART-meso cells via intravenous (IV) administration at the same dose level, given between 21-42 days apart. The subject must meet eligibility to receive additional infusions. Lymphodepleting chemotherapy will not be repeated prior to additional infusions of huCART-meso cells. huCART-meso cells: Intravenous administration or local delivery of lentiviral transduced huCART-meso cells in 7 cohorts with or without lymphodepletion..
