Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase I study evaluating the safety and feasibility of lentiviral transduced huCART-meso cells in up to 4 cohorts. Lymphodepleting chemotherapy will not be utilized as part of the planned dosing strategy.

• Cohort 1 (N=3-6): will receive a single dose of 1-3x10^7/m^2 lentiviral transduced huCART-meso cells on day 0 via intravenous infusion.

  • Enrollment into Cohort 1 will be paused after the 3rd subject is infused to allow for a formal DLT assessment (performed by the Clinical PI and Medical Director) and DSMB review. If 1 DLT/3 subjects occurs in Cohort 1, the Sponsor (with guidance from the DSMB), will determine whether the study will enroll an additional 3 subjects at this dose level to further establish safety via intravenous infusion, or advance to Cohorts 2 and 3 to explore local delivery of huCART-meso cells at the same dose level. If 0 DLT/3 subjects or 1 DLT/6 subjects occurs at any time, the study may advance to Cohorts 2 and 3.
  • If 2 DLTs occur at this dose level at any time, enrollment in Cohort 1 will be stopped and the dose will be de-escalated by 10-fold to 1-3x10^6 cells/m^2 (Cohort -1).
  • The infusions in Cohort 1 will be staggered by at least 28 days to allow for the assessment of DLTs for cohort progression, expansion, or dose de-escalation.

In the event that 2 DLTs occur among subjects enrolled in Cohort 1, then enrollment in Cohort 1 will be stopped and the dose will be de-escalated by 10-fold to 1-3x10^6 cells/m^2. This de-escalated cohort will be designated Cohort -1.

• Cohort -1 (N=3-6): will receive a single dose of 1-3x10^6 cells/m^2 lentiviral transduced huCART-meso cells on day 0. Up to 6 subjects will be infused in Cohort -1 if ≤ 1 DLT occurs.

If 0 DLT/3 subjects or 1 DLT/6 subjects occurs in Cohort 1, the study will advance to allow for additional cohorts to be explored.

  • Cohorts 2 and 3. Enrollment into these additional cohorts may occur in parallel, however infusions will be staggered as follows to allow for monitoring/assessment of toxicities:
  • Cohorts 2 and 3: As of Protocol Amendment V7, Infusion #1/Day 0 for the next 6 subjects in Cohorts 2 and 3 must be staggered by at least 28 days; This includes a minimum of 3 evaluable subjects in Cohort 2 and 3 evaluable subjects in Cohort 3. A DLT assessment will be performed after the 3rd evaluable subject in each cohort reaches the Day 21 safety follow-up visit. If no DLTs are identified in the 1st three evaluable subjects in both Cohorts 2 + 3, subsequent infusions of new subjects within either cohort may occur in parallel; however, no more than two new subjects may be infused within a 14-day period, irrespective of cohort assignment. If both cohorts have not yet infused 3 evaluable subjects without a DLT, all infusions will continue to be staggered by 28 days until this provision is met.

  • Cohort 4: Infusion #1/Day 0 for the first 3 subjects in Cohort 4 must be staggered by at least 28 days. A DLT assessment will be performed after the 3rd evaluable subject in this cohort reaches the Day 21 safety follow-up visit. If no DLTs are identified in the 1st three evaluable subjects, subsequent infusions of new subjects may occur in parallel, however no more than two new subjects may be infused within a 14-day period. If 1 DLT is identified in the 1st three evaluable subjects, Infusion #1 for all subsequent subjects will continue to be staggered by at least 28 days and DLT assessments will be performed after each evaluable subject reaches the Day 21 safety follow-up visit.

    • Cohort 2 Participants (N = Up to 6): will receive a single dose of 1-3x10^7/m^2 lentiviral transduced huCART-meso cells on day 0 via intraperitoneal (i.p.) administration. The 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.

**Cohort 2 is prematurely closed. This closure is the result of feasibility concerns specific to the clinical/disease status of these patients at this stage of their treatment.**

• Cohort 3 Participants (N = Up to 6): will receive a single dose of 1-3x10^7/m^2 lentiviral transduced huCART-meso cells on day 0 via intrahepatic delivery (Hepatic Arterial Infusion). The initial intrahepatic 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.

**Cohort 3 is prematurely closed. This closure is the result of feasibility concerns specific to the clinical/disease status of these patients at this stage of their treatment.**

• Cohort 4 Participants (N = Up to 6): will allow for the administration of lentiviral transduced huCART-meso cells during 1st line standard of care chemotherapy. A single dose of 1-3x10^7/m^2 huCART-meso cells will be administered on day 0 via intrahepatic delivery (Hepatic Arterial Infusion), following a 1 week washout after standard of care chemotherapy. This initial intrahepatic 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 all eligibility to receive additional infusions. Additional doses of standard of care chemotherapy may also be administered between huCART-meso infusions at the physician-investigator's discretion, as long as the required washout windows are appropriately adhered to. huCART-meso infusions may also be discontinued at any time in favor of resuming standard of care chemotherapy at the physician-investigator's discretion.

Adverse events will be collected and evaluated during the protocol specified adverse event reporting period. Subjects will be continually evaluated for dose-limiting toxicities (DLT). In the event of 2 DLTs in a specific cohort, additional enrollment and treatment activity will be paused to allow for further investigation.
