Brief Summary:
Phase I study to establish safety and feasibility of both intravenous administration and local delivery of lentiviral transduced huCART-meso cells with or without lymphodepletion.

Condition or disease Intervention/treatment Phase
Lung Adenocarcinoma Ovarian Cancer Peritoneal Carcinoma Fallopian Tube Cancer Mesotheliomas Pleural Mesothelioma Peritoneum Biological: huCART-meso cells Phase 1

Detailed Description:

This is a Phase I study evaluating the safety and feasibility of lentiviral transduced huCART-meso cells with and without cyclophosphamide and via different routes of administration.

  • Cohort 1 (N=3-6): will receive a single dose of 1-3x10^7 /m^2 lentiviral transduced huCART-meso cells on day 0 without any conditioning chemotherapeutic regimen.
  • Cohort 2 (N=3-6): will receive a single dose of 1-3x10^7 /m^2 lentiviral transduced huCART-meso cells on day 0, following a flat dose of 1 gram/m2 of cyclophosphamide administered 2-4 days prior to huCARTmeso cells (day -4 to day -2).
  • Cohort 3 (N=3-6): will receive a single dose of 1-3x10^8 /m^2 lentiviral transduced huCART-meso cells on day 0 without any conditioning chemotherapeutic regimen. **Cohort 3 permanently closed**
  • Cohort 4 subjects (N=3-6) will receive a single dose of 1-3x10^8 /m^2 lentiviral transduced huCART-meso cells on day 0, following a flat dose of 1 gram/m^2 of cyclophosphamide administered 2-4 days prior to huCART-meso cells (day -4 to day -2). **Cohort 4 permanently closed**
  • Cohort 5 (N=up to 6): will receive a single dose of 1-3x10^7 /m^2 lentiviral transduced huCART-meso cells on day 0 by intrapleural infusion (IP) through an indwelling pleural catheter without any conditioning chemotherapeutic regimen. The safety of this dose level has been established by Cohorts 1 and 2.
  • Cohort 6 (N=up to 6): will receive lentiviral transduced huCART-meso cells at a dose of 1-3x10^7 via IV infusion on Day 0, following a flat dose of 1 gram/m^2 of cyclophosphamide administered 2-4 days prior to huCART-meso cells (~Day -4 to -2). This initial infusion may be followed by up to two additional IV infusions of huCART-meso cells at the same dose level, given between 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. Enrollment into Cohort 6 will occur in parallel with Cohort 5.
  • Cohort 7 (N = up to 6): will receive a single dose of 1-3x107 huCART-meso cells/m2 via intraperitoneal (i.p.) administration, following lymphodepleting chemotherapy with cyclophosphamide 300 mg/m2/day and fludarabine 30 mg/m2/day given over 3 days by intravenous infusion. Lymphodepleting chemotherapy will be scheduled such that the last day of chemotherapy is 3 days (+/- 1 day) prior to the 1st 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.

The Maximum Tolerated Dose (MTD) is defined as the dose at which 0-1 DLT occurs in 6 evaluable subjects tested within the dose range of this study. The maximum tolerated dose has been established as 1-3x10^7/m^2 lentiviral transduced huCART-meso cells.

Adverse events will be collected and evaluated during the protocol specified adverse event reporting period
