Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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

Investigators will enrolle 100 patients who met the enrollment criteria. 50 patients were clinically confirmed EGFR mutation positive. They were divided into two groups (group A and group C according to if accepted NK therapy) in accordance with the principles of randomized. The rest 50 patients which were EGFR mutation negative were also divided into two groups (group B and group D) in accordance with the principles of randomized to be paired respectively with group A and group C. Comparison of lymphocyte number, serum tumor related biomarkers, circulating Tumor Cell (CTC), KPS and survival curves was carried out before after NK cell immunotherapy. The safety and short-term effects were evaluated followed by the median PDA, response rate assessment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

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.
Experimental: EGFR+NK+
The EGFR mutation positive patients were with the principles of randomized and NK cells treatment.
Biological: NK cells

NK cells were generated in good manufacturing practice (GMP) condition. In brief, PBMCs were isolated from 50mL patient's blood with Ficoll-Hypaque(Morecell Biomedical Co. Ltd., Shenzhen, China). Then the Human NK Cell Culture Kit (Cat. No.

MCF-004, Morecell Biomedical Co. Ltd., Shenzhen, China) and Serum-free Medium for NK Cells (MCM-002, Morecell Biomedical Co. Ltd., Shenzhen, China) was used for induction of NK cells according to the manufacturer's instructions. Three days before NK cell transfusion, the NK cells were sampled and sent to detect the NK cell quality.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Clinical response
Time Frame: Calculated the sum area of all tumors 3 months after NK treatment
Based on the Response Evaluation Criteria Solid Tumors (RECIST), the therapeutic effect was divided into complete response (CR), partial response (PR),stable disease (SD), progressive disease (PD). Investigators calculated the sum area of all tumors 3 months after NK treatment. The recent curative effect must have been maintainedat >4 weeks; CR + PR denoted the effective response rate (RR).
Calculated the sum area of all tumors 3 months after NK treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Detection of immune function
Time Frame: Before and 3 months after NK cell therapy
Patients were detected Lymphocyte subgroups of 1ml peripheral blood by Flow cytometer (BD FACSCalibur), which inclunde the T cell number, CD4T cell number, CD8 T cell number and NK cell number.
Before and 3 months after NK cell therapy
Analysis of tumor biomarker CEA and CA125 levels in serum
Time Frame: Before and 3 months after NK cell therapy

Patients were detected the Serum Carcinoembryonic antigen (CEA) and CA125 level by Elisa kit.Investigators compared the level of CEA and CA125 in serum before and 3 months after NK cell therapy to perform the therapeutic evaluation.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Measure Description
Time Frame
The endpoints of interest were progression-free survival (PFS).
