Brief Summary:
The purpose of this study is to observe and confirm the safety, tolerance and cell pharmacokinetics of lentivirus-transduced CAR-GPC3 T cells (CAR-GPC3 T cells targeting GPC3)

Condition or disease Intervention/treatment Phase
Lung Squamous Cell Carcinoma Genetic: CAR-GPC3 T Cells Drug: Fludarabine Drug: Cyclophosphamide Phase 1

Detailed Description:

A single-center, open-label pilot study to determine the safety, tolerance and engraftment potential of CAR-GPC3 T cells in subjects with GPC3+ positive lung squamous cell carcinoma.

Primary objectives:

Observe and determine the safety and tolerance in escalating dose infusion of CAR-GPC3 T cells (CAR T cells targeting GPC3) transduced with the lentiviral vector, and the survival of the CAT-GPC3 T cells in vivo, referred to as engraftment potential.

Secondary objectives:

The following indexes are monitored for curative effect of CAR-GPC3 T cells on lung squamous cell carcinoma:

  1. Objective response rate (ORR), is defined as the ratio of patients diagnosed as partial remission (PR) to complete remission (CR) according to RECIST 1.1 criteria.
  2. Progression free survival (PFS), is defined as the duration from baseline to PD (audited and confirmed by independent imaging), or to the day of any death event. The earlier one shall prevail.
  3. Time to tumor progression (TTP), is defined as the duration from baseline to disease starts to get worse or spreads to other parts of the body.
  4. Overall survival (OS), is defined as the time period from the 1st day of treatment to the day of death for any reason. For patients who are still alive at the data analysis day, OS data is subject to the last confirmed time of survival patients.

Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Preliminary Clinical Study of Autologous T Cells Modified Chimeric Antigen Receptor (CAR) Targeting GPC3 for the Treatment of Recurrent or Refractory Lung Squamous Cell Carcinoma
Study Start Date : March 2016
Estimated Primary Completion Date : October 2017
Estimated Study Completion Date : April 2019

Arm Intervention/treatment
Experimental: CAR-GPC3 T cells

Intravenous infusion with escalating dose is adopted in this study.

Total dosage: 1 x 10^5 - 2 x 10^9 CAR-GPC3 T cells/kg

The next dose and interval depends on the response of the subject to previous dose.

Lymphodepletion:

Fludarabine: 30 mg/m^2/day x 4 days; Cyclophosphamide: 500 mg/m^2/day x 2 days. Adjustment is in discretion of the investigator based on individual response.

Genetic: CAR-GPC3 T Cells
Intravenous infusion of CAR-GPC3 T cells is conducted 1 - 2 days following lymphodepletion.
Other Names:
  • Anti-GPC3 CAR T
  • CAR T cells redirected to Glypican-3

Drug: Fludarabine
30 mg/m^2/day x 4 days

Drug: Cyclophosphamide
500 mg/m^2/day x 2 days




Primary Outcome Measures :
  1. Safety and tolerance: Occurrence of study related adverse events [ Time Frame: 24 weeks ]
    Occurrence of study related adverse events, defined as laboratory toxicities and clinical events that are possibly, likely or definitely related to study treatment at any time from the infusion until week 24. This will include infusive toxicity, and any toxicity possibly related to the CAR-GPC3 T cells.


Secondary Outcome Measures :
  1. Engraftment: the DNA vector copies per mL blood of CAR-GPC3 T cells [ Time Frame: 2 years ]
    The DNA vector copies per mL blood of CAR-GPC3 T cells on week 4 after the first infusion by Q-PCR. Q-PCR for CAR-GPC3 vector sequences will also be performed after infusion thereafter until any 2 sequential tests are negative documenting loss of CAR-GPC3 T cells within 2 years.
