A Randomized Phase II/III Trial of Afatinib Plus Cetuximab Versus Afatinib Alone in Treatment-Naive Patients With Advanced, EGFR Mutation Positive Non-small Cell Lung Cancer (NSCLC)

This randomized phase II/III trial studies how well afatinib dimaleate with cetuximab works and compares it with afatinib dimaleate alone in treating patients with newly diagnosed stage IV or recurrent (has come back), epidermal growth factor receptor (EGFR) mutation positive non-small cell lung cancer. Afatinib dimaleate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab, may block tumor growth in different ways by targeting certain cells. It is not yet known whether afatinib dimaleate is more effective when given alone or with cetuximab in treating patients with non-small cell lung cancer.

Primary Outcomes

Measure: OS (phase III)

Time: From date of registration to date of death due to any cause, assessed up to 3 years

Measure: PFS (phase II)

Time: From date of registration to date of first documentation of progression or symptomatic deterioration or death due to any cause, assessed up to 3 years

Secondary Outcomes

Measure: PFS

Time: From date of registration to date of first documentation of progression or symptomatic deterioration or death due to any cause, assessed up to 3 years

Description: Compared between arms using a chi-squared test of independence at the 1-sided 5% level.

Measure: Response rates

Time: Up to 3 years

Measure: Time to treatment discontinuation

Time: From date of registration to date of discontinuation of treatment or death due to any cause, assessed up to 3 years

Measure: Time to treatment failure

Time: From date of registration to date of first documentation of progression or symptomatic deterioration, early discontinuation of treatment, or death due to any cause, assessed up to 3 years

Description: Assessed using a chi-squared or Fisher's exact test (as appropriate) at the 1-sided 5% level.

Measure: Toxicity rates assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0

Time: Up to 3 years

Other Outcomes

Description: For each of these markers, a one-sample t-test (or Wilcoxon signed-rank test) will be used to test the null hypothesis that the absolute difference between the copy number after progression and the copy number in the pre-treatment specimen (or an appropriate transformation of the difference, determined after exploratory data analysis) is not equal to zero.

Measure: Change in copy number alterations in MET, EGFR, and HER2, analyzed using fluorescence in situ hybridization

Time: Baseline up to 3 years (after disease progression)

Description: To evaluate if EGFRs/EGFR T790M is lower at progression than in pre-treatment specimens among patients with results available for pre-treatment and progression, a one-sample t-test (or Wilcoxon signed-rank test) will be used to test the null hypothesis that the difference between the progression ratio and the pre-treatment ratio (or an appropriate transformation of the difference, determined after exploratory data analysis) is greater than zero in favor of the alternative that the difference is less than zero.

Measure: Change in the ratio of sensitizing EGFR mutation to EGFR T790 mutation

Time: Baseline up to 3 years (at progression)

Description: To evaluate the hypothesis that H-score positive status at baseline is associated with absolute difference in PFS (and OS) among patients randomized to receive afatinib dimaleate monotherapy a test of interaction will be performed at the 1-sided 20% level.

Measure: EGFR immunohistochemistry H-score

Time: Baseline

Description: Tumor marker levels over time will be evaluated using a linear mixed model for continuous markers and using generalized estimating equations for binary markers. A landmark analysis will be used to evaluate the correlation between post-randomization biomarker values and PFS and OS (from the landmark timepoint) using a Cox proportional hazards model.

Measure: Levels of circulating tumor markers

Time: Up to 3 years

Description: To evaluate if the presence of de novo T790M mutation is associated with primary resistance to afatinib dimaleate, PFS and OS will be compared between T790M mutation positive and negative patients randomized to the afatinib dimaleate monotherapy arm using a log-rank test..

Measure: Presence of de novo EGFR T790M mutation or other molecular alterations

Time: Baseline

Description: To evaluate if the ratio of EGFR sensitizing mutation to EGFR T790M mutation (EGFRs/EGFR T790M) among patients with T790M is predictive for afatinib dimaleate monotherapy, analyses will be performed in a similar fashion to the evaluation of T790M among patients with measurable T790M (which defines T790M). Cox regression will be used to assess the predictive association of the ratio in the afatinib dimaleate monotherapy arm with both OS and PFS

Measure: Ratio of sensitizing EGFR mutation to EGFR T790 mutation

Time: Up to 3 years

Purpose: Treatment

Allocation: Randomized
