Study summary

Our project is going to enroll patients with stage IV NSCLC with EGFR mutation and evaluate whether primary tumor resection after receiving the afatinib can prolong survival. This project is supposed to establish a new treatment protocol for stage IV NSCLC with EGFR mutation.

Read the detailed description

In Taiwan, non-small cell lung cancer (NSCLC) has been the leading cause of cancer death, making a phenomenal impact on public health. By understanding the oncogenic driver mutations of NSCLC (e.g. EGFR mutation or ALK rearrangement), the target therapy has taken the place of chemotherapy for its effectiveness and specificity, becoming the new standard of care for stage IV NSCLC. Despite the progress of medical treatment, the majority of patients with stage IV NSCLC still underwent disease progression after a period of time. Noticeably, more than half of the progression was restricted to the original sites of the tumor. It brings up the hypothesis that a combination of local consolidative therapy (e.g. surgery or radial therapy) and medical treatment could be beneficial for these patients. This has been advocated by the latest clinical trials as well.

Our project is going to enroll patients with stage IV NSCLC with EGFR mutation and evaluate whether primary tumor resection after receiving the afatinib can prolong the progression-free survival. This project is supposed to establish a new treatment protocol for stage IV NSCLC with EGFR mutation.

Exclusion criteria

Exclusion Criteria:

  • \<= 12 weeks
  • With underlying diseases such as moderate to severe or tuberculosis
  • With uncontrol diseases including acute infection, unstable angina or angina in recent 3 months, Heart failure(≥2), myocardial infarction in recent 6 months, severe arrhythmia, moderate to severe cirrhosis, moderate to severe chronic renal insufficiency, immune insufficiency, any systemic disease with poor prognosis after treatment.

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Study arms

  • Experimental
    Group I : Surgery group

    The surgery group would receive take 12 weeks of EGFR TKI before randomization. After randomization, the surgery group would receive thoracic surgery with maximal regional control intent. Patients continue afatinib 1 to 2 weeks after surgery until disease progression or unacceptable toxicity. The residual local and metastatic sites of disease could undergo either surveillance or maintenance radio-treatment at the discretion of the treating physician.

    Procedure: therapeutic thoracic surgery · Drug: Afatinib

  • Active comparator
    Group II : Maintenance group

    The control group would receive take 12 weeks of EGFR TKI before randomization. After randomization, the control group would receive afatinib until disease progression or unacceptable toxicity. The residual local and metastatic sites of disease could undergo either surveillance or maintenance radio-treatment at the discretion of the treating physician.

    Drug: Afatinib

Interventions

  • Proceduretherapeutic thoracic surgery

    The surgery group would receive therapeutic thoracic surgery with maximal local regional control intent and would prescribe with maintenance afatinib therapy after operation. Patients continue afatinib 1 to 2 weeks after surgery.

  • The patient take afatinib treatment for 12 weeks treatment and then receive systemic image study examination before randomization. If exam result showed progression the patient would be excluded from the study. Treatment response was evaluated according to the Response Evaluation Criteria in Solid Tumors (version 1.1).

What researchers measure

Primary outcomes

  1. 2 year progression free survival rate

    Will be estimated using Kaplan-Meier method. The stratified log-rank test will be performed to test the difference in time-to-event distributions between treatment groups. Stratified Cox proportional hazards model will be utilized to include multiple covariates in the time-to-event analysis and to estimate hazard ratios.

    Time frame: start date of afatinib assessed up to 2 years

Secondary outcomes

  1. Progression free survival

    Will be estimated using Kaplan-Meier method. The stratified log-rank test will be performed to test the difference in time-to-event distributions between treatment groups. Stratified Cox proportional hazards model will be utilized to include multiple covariates in the time-to-event analysis and to estimate hazard ratios.

    Time frame: From the start date of afatinib assessed up to 4 years

  2. Overall survival

    Will be estimated using Kaplan-Meier method. The stratified log-rank test will be performed to test the difference in time-to-event distributions between treatment groups.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Sep 2021 (actual). Primary completion is estimated for Oct 2026, 61 months after the start.

Of 730 non-industry phase 2 interventional studies under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 56 months of starting (the median), counting those still running; a quarter within 36 and three quarters within 84. This study's planned 61 months is close to that.

Counting every sponsor, half of 1,047 studies reached it within 48 months; a quarter within 30 and three quarters within 76.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
