Intervention of Engineered Immune Effector T Cells Against Lung Cancer

Phase 1

Withdrawn

• Conditions: Lung Cancer; NSCLC
• Interventions: Biological: LC-CTLs

• Registration Number: NCT03353428
• Lead Sponsor: Shenzhen Geno-Immune Medical Institute

Brief Summary

The primary objective of this study is to evaluate the safety of lung cancer specific cytotoxic lymphocytes (LC-CTLs). The secondary objectives are to evaluate the rate of successful LC-CTLs generation in vitro and determine the anti-lung cancer efficacy.

Detailed Description

Lung cancer is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. The two main types are small-cell lung carcinoma (SCLC) and non-small-cell lung carcinoma (NSCLC). Worldwide in 2012, lung cancer occurred in 1.8 million people and resulted in 1.6 million deaths. Common treatments include surgery, chemotherapy, and radiotherapy.

Adoptive immunotherapy with cytotoxic T lymphocytes (CTLs) reactive with specific viral antigens has proven to be effective. Here, the investigators aim to evaluate the safety and efficacy of multiple infusions of lung cancer specific cytotoxic T lymphocytes cells in patients.

Arm && Interventions

Group	Intervention	Description
LC-CTLs	LC-CTLs	Autologous lung cancer specific cytotoxic lymphocytes

Primary Outcome Measures

Name	Time	Method
Safety of LC-CTLs in patients using CTCAE version 4.0 standard to evaluate the level of adverse events	3 months	Physiological parameter (measuring cytokine response)

Secondary Outcome Measures

Name	Time	Method
Functional analyses of LC-CTLs in vitro	2 weeks	The specificity of LC-CTLs in vitro will be analysed by intracellular cytokine staining (ICCS) or enzyme-linked immunospot assay (ELISPOT).
Anti-tumor effects	1 year	Biochemical markers and image scan will be got before and after treatment. Objective response, such as complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD) will be assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria.
