About this study

Official title: A Retrospective, Non-interventional Study to Evaluate EGFR-Tyrosine Kinase Inhibitor Retreatment in Patients With Locally Advanced or Metastatic EGFR Mutated NSCLC Who Previously Treated With EGFR-TKI as First-line Therapy and Chemotherapy as Second-line Therapy - SEQUENCE Study

This is a retrospective, non-interventional, multicenter, observational chart review study to explore the clinical benefits of retreatment with TKI in the real world.

Read the detailed description

This study is designed to retrospectively review the medical and chemotherapy records of 300 patients with EGFR mutation positive adenocarcinoma NSCLC. Eligible patients are as follows: histologically or cytologically confirmed NSCLC, undergone EGFR-TKI retreatment sometime after the failure of the initial EGFR-TKI. After initial treatment, patients had been treated with chemotherapy and subsequently re-treated with EGFR-TKI will be identified. The target population will be derived from multicentre in Taiwan. The study aim is to evaluate clinical effect in re-administration of EGFR-TKI using retrospectively collected data from these eligible patients to provide valuable information.

What is being measured

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

  1. The treatment duration of Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor re-administration

    The median duration of re-administration of Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor will be summarized by days or months, if applicable. The range of this treatment duration will also be presented. All analyses will be performed on all eligible patients in this study.

    Measured: From the start of re-administration of EGFR-TKI to data cut-off date, assessed approximately up to 6 months.

Secondary outcomes (10)
  1. Assessment of progression-free survival for initial, second EGFR-TKI treatment and chemotherapy between two Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor treatments.

    The outcome of progression-free survival will be presented with median values and associated 95% CIs by Kaplan-Meier curve. PFS is defined as the time interval (in weeks) from the start date of a given treatment to the date of disease progression or death, respectively, which one is observed first. Subjects who did not progress or die without a reported progression will be censored on the date of their last tumor assessment.

    Measured: From the start of administration of EGFR-TKI to data cut-off date, assessed approximately up to 6 months.

  2. Assessment of overall survival for initial, second EGFR-TKI treatment and chemotherapy between two Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor treatments.

    The outcome of overall survival will be presented with median values and associated 95% CIs by Kaplan-Meier curve. OS is defined as the time interval (in weeks) from the beginning of treatment until the date when death or lost to follow up is observed. For those subjects who have not died or lost to follow-up, survival duration will be censored at the last date the subject was known to be alive.

    Measured: From the start of administration of EGFR-TKI to data cut-off date, assessed approximately up to 6 months.

  3. Assessment of response rate for initial, second EGFR-TKI treatment and chemotherapy between two Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor treatments.

    The outcome about response rate and the proportion of response rate are estimated by all evaluable patients. The 95% exact confidence interval will be constructed around the rates. The best response during treatment sequences is determined in accordance with the Response Evaluation Criteria in Solid Tumors (RECIST) guidelines.

    Measured: From the start of administration of EGFR-TKI to data cut-off date, assessed approximately up to 6 months.

  4. Assessment of disease control rate for initial, second EGFR-TKI treatment and chemotherapy between two Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor treatments.

    The outcome of disease control rate are estimated by all evaluable patients. The 95% exact confidence interval will be constructed around the rates. Disease Control Rate is defined as patients who are respond to treatment (including CR-complete respond, PR-partial respond or SD- Stable Disease).

    Measured: From the start of administration of EGFR-TKI to data cut-off date, assessed approximately up to 6 months.

  5. Record treatment duration in the initial EGFR-TKI therapy and first time chemotherapy.

    Treatment duration in the initial EGFR-TKI therapy and first time chemotherapy.

    Measured: Between the initial EGFR-TKI therapy and first time chemotherapy.

  6. Record the reason(s) for treatment change for initial and re-administration of EGFR-TKI therapy and first time chemotherapy (second-line treatment).

    Record the reason(s) for treatment change for initial and re-administration of EGFR-TKI therapy and first time chemotherapy (second-line treatment).

    Measured: From the start of administration of EGFR-TKI to data cut-off date, assessed approximately up to 6 months.

  7. Explore relationships between efficacy of EGFR-TKI initial and re-administration and patient characteristics or EGFR TKI treatment characteristics.

    Explore relationships between efficacy of EGFR-TKI initial and re-administration and patient characteristics (including demographics, histology, disease stage, sites of metastasis, ECOG PS) or EGFR TKI treatment characteristics (including EGFR mutation pattern, response to initial EGFR TKI or not, length of duration between first and second EGFR-TKI treatment)

    Measured: EGFR-TKI initial and re-administration

  8. overall survival (OS), plasma CEA level and chemotherapy regimens ever used.

    Explore overall survival (OS), plasma CEA level and chemotherapy regimens ever used between first time chemotherapy and EGFR-TKI re-administration (including the types and number of chemotherapy regimens, and treatment duration) for those patients who have the above data available.

    Measured: between first time chemotherapy and EGFR-TKI re-administration

  9. image peer review to evaluate tumour size retrospectively in different sequences of treatment

    If the images are available, conduct image peer review to evaluate tumour size retrospectively in different sequences of treatment: (1) initial and re-administration of EGFR-TKI therapy, (2) first time chemotherapy ever used (second-line treatment) after initial EGFR-TKI treatment. Peer review time point includes baseline, best response and progression of last image while stopping treatment at each treatment mentioned above.

    Measured: (1) initial and re-administration of EGFR-TKI therapy, (2) first time chemotherapy ever used (second-line treatment) after initial EGFR-TKI treatment.

  10. The reason(s) for the treatment change for initial and re-administration of EGFR-TKI therapy and first time chemotherapy (second-line treatment) after peer review

    Evaluate the reason(s) for the treatment change for initial and re-administration of EGFR-TKI therapy and first time chemotherapy (second-line treatment) after peer review and compare the difference of reason(s) for the treatment change between initiatial evaluation and after peer review.

    Measured: Initial and re-administration of EGFR-TKI therapy and first time chemotherapy (second-line treatment) after peer review.
