About this study

Official title: Determine the Optimal EGFR TKIs Treatment Strategies for Lung Adenocarcinoma Harboring EGFR Exon 19 Deletion Variants : the Clinical Analysis and Cell Lines Study

To determine the optimal EGFR TKIs treatment strategies for lung adenocarcinoma harboring EGFR exon 19 deletion variants

Read the detailed description

RNA extraction: The investigators will extract total RNA from cell lysates by using Tri-reagent (Molecular Research Center, Inc., Cincinnati, Ohio) and an RNA Mini Kit (Qiagen, Hilden, Germany) according to the manufacturer's instruction. RNA obtained from the Mini Kit column will be eluted. The quantity and quality of the purified RNA will be evaluated using a NanoDrop ND-1000 spectrophotometer will be stored at -80 °C for further mutational analyses.

Data acquisition: The investigators will record and follow participants' clinical information, including ethnicity, age, gender, smoking status, histological types, lung cancer stage (the TNM status), metastatic sites, ECOG score, CT/CXR imaging, chemotherapy or radiation treatment at the time of diagnosis of lung cancer and through the entire clinical courses. Specific marker such as TTF1, is used to ensure the diagnosis of primary lung tumor. Clinicopathologic stage assigns according to the seventh tumor-node-metastasis classification. The investigators assess the treatment responses according to the Response Evaluation Criteria in Solid Tumors (RECIST) using the unidimension method, and record the best response achieved per treatment. Treatment response, progression-free survival, and overall survival are recorded prospectively for further analysis.

Statistical analysis: All categorical variables will be analyzed with Pearson's χ² test, except where a small size required the use of Fisher's exact test. The progression-free survival curve and overall survival will be plotted by the Kaplan-Meier method and compared by the log-rank test. Multivariate analysis for overall survival will be performed using the Cox's proportional hazards model. Two-sided p-values of less than 0.05 is considered significant. All analyses will be performed using SPSS software (version 16.0 for Windows; SPSS Inc.).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Tumor size measurement for evaluating tumor progression

    Tumor size is recorded using CT scan before the first day of of treatment and routine CT scan image is captured at each cycle of treatment to evaluate the growth of tumor.

    According to RECIST (The Response Evaluation Criteria in Solid Tumors), tumor progression will be assigned based on (1) a sum measurement of original target lesions that has increased more than 20%, (2) the reappearance of the original target lesions, (3) appearance of new lesions, and (4) a new lymph node metastatic lesion which is more than 10mm in diameter. Statistically, patients will be divided into several groups according to Exon 19 deletion variants, which is detected before the first day of treatment. The clinicopathologic characteristics (sex, age, smoking history) will be enrolled in multivariate analysis.

    Measured: "up to 5 years," "from date of treatment (EGFR TKIs) until the date of first documented progression

Questions about this trial

What is this clinical trial studying?

An observational study of EGFR Exon 19 Mutation and Tumor Progression, run by National Taiwan University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Tumor size measurement for evaluating tumor progression (time frame: "up to 5 years," "from date of treatment (EGFR TKIs) until the date of first documented progression). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2022.
