T Cell Mediated Adaptive Therapy for Her2-positive Neoplasms of Digestive System

January 20, 2016 updated by: Yi Miao
This phase I trial is to investigate the safety and the possible side effects of bi-specific antibody armed T-cell therapy when given together with low-dose IL-2 in treating patients with Her2-positive neoplasms of digestive system. Expanded autologues T cells that have been coated with bi-specific antibodies, such as anti-CD3 and anti-human epidermal growth factor receptor 2 (HER2), may stimulate the immune system in different ways and stop tumor cells from growing. Interleukin-2 may stimulate white blood cells to kill tumor cells.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. Perform a phase I clinical trial to clearly define the toxicity profile of IV HER2Bi armed T cells in patients with neoplasms of digestive system.

SECONDARY OBJECTIVES:

I. Evaluate phenotype, cytokine profiles and tumor markers, cytotoxicity directed at laboratory Her2 positive cancer cell lines.

II. Evaluate the clinical symptoms and signs, clinical responses, imaging examination of pretherapy and post-treatment, cytokine profiles and tumor markers in serum before and after treatment, time to progression, and overall survival.

OUTLINE: This is a safety study of IV infused HER2Bi-armed activated T cells. Patients receive HER2Bi armed T cells IV weekly for 4 weeks. Patients also receive low-dose Interleukin subcutaneously (SC) daily beginning 3 days before the first HER2Bi armed T cells infusion. Treatment continues in the absence of disease progression or unacceptable toxicity.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
Safety as measured by local and systemic toxicities
Time Frame: Up to 1 year
Up to 1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes in cytokine profiles and tumor markers in serum before and after treatment
Time Frame: Baseline to up to 12 months
Increases or decreases in the amount of cytokine produced from the pre-immunotherapy baseline at any time point after immunotherapy will be considered as continuous outcomes.
Baseline to up to 12 months
Changes in phenotyping induced by immunotherapy in peripheral blood mononuclear cells (PBMC)
Time Frame: Baseline to up to 12 months
PBMC from the patients will be obtained before and after immunotherapy to determine if there are any phenotype changes induced by immunotherapy. Paired t-test will be used to compare the difference between baseline and after any time point of armed T cells treatment in T cell subpopulation (FACS), tumor marker (CBA/ELISA) and tumor killing ability of PBMC.
Baseline to up to 12 months
Clinical response rate (including clinical symptoms and signs, complete response, partial response, progressive disease, and stable disease, imaging examination of pretherapy and post-treatment) will be measured by follow-up investigation.
Time Frame: Up to 12 months
Point and exact confidence interval estimates will be calculated for response rate.
Up to 12 months
Overall survival
Time Frame: Up to 12 months
Will be estimated with the standard Kaplan-Meier method, from which summary statistics of interest (median, 6 month, 1-year rate, etc.) will be derived. Both point and 95% confidence interval estimates will be calculated.
Up to 12 months
Progression free survival
Time Frame: From the beginning of immunotherapy to progression or death, assessed up to 12 months
Will be estimated with the standard Kaplan-Meier method, from which summary statistics of interest (median, 6 month, 1-year rate, etc.) will be derived. Both point and 95% confidence interval estimates will be calculated.
From the beginning of immunotherapy to progression or death, assessed up to 12 months
