Recurrent Non-Small Cell Lung Carcinoma, Stage IV Non-Small Cell Lung Cancer
Conditions
Brief summary
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.
Detailed description
PRIMARY OBJECTIVES: I. To evaluate if there is sufficient evidence to continue to the phase III component by comparing progression-free survival (PFS) between patients randomized to afatinib (afatinib dimaleate) in combination with cetuximab versus afatinib alone in the first-line treatment of patients with advanced EGFR-mutant non-small cell lung cancer (NSCLC). (Phase II) II. To determine the efficacy of the combination of afatinib and cetuximab compared to afatinib alone as measured by overall survival (OS) in the first-line treatment of patients with advanced EGFR-mutant NSCLC. (Phase III) SECONDARY OBJECTIVES: I. To evaluate the overall response rate (confirmed and unconfirmed, complete and partial responses) in the subset of patients with measurable disease treated with afatinib plus cetuximab compared to afatinib alone. II. To assess the safety of each treatment arm when used in the first-line setting. III. To compare time to treatment failure and time to treatment discontinuation between randomized to afatinib in combination with cetuximab versus afatinib alone. TERTIARY OBJECTIVES: I. To investigate the molecular mechanisms that confer benefit from afatinib and afatinib plus cetuximab by evaluating whether the presence of de novo EGFR T790M mutation or other molecular alterations in the pre-treatment tumor influence the clinical outcomes. II. To quantitatively assess whether the ratio of sensitizing EGFR (EGFRs) mutation to EGFR T790M influences outcome and is altered during treatment. III. To evaluate the frequency of known mechanisms of resistance to EGFR-directed therapies in the context of afatinib plus cetuximab and afatinib alone treatment. IV. To identify potential novel predictors of benefit to afatinib plus cetuximab. V. To identify potential new mechanisms of resistance to EGFR-directed therapies. VI. To establish patient-derived xenografts (PDXs) from a subset of patients by re-biopsy at the time of progressive disease for drug testing and genomic analysis. VII. To assess whether circulating tumor markers can be used as indicators of sensitivity and resistance to afatinib plus cetuximab and afatinib alone. VIII. To determine whether the levels of EGFR protein by immunohistochemistry predict for benefit to afatinib plus cetuximab and afatinib alone. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive afatinib dimaleate orally (PO) once daily (QD) on days 1-28 and cetuximab intravenously (IV) over 2 hours on days 1 and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive afatinib dimaleate as in Arm I. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 3 years.

Secondary
Response Rates
Percentage of participants with confirmed and unconfirmed, partial response and complete response to treatment Response Evaluation Criteria in Solid Tumors Criteria (RECIST 1.1). Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of appropriate diameters of all target measurable lesions; Overall Response (OR) = CR + PR.
Time frame: Up to 3 years
Population: Eligible participants that were randomized to study arms and who had baseline measurable disease (153)
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Arm I (Afatinib Dimaleate, Cetuximab) | Response Rates | 67 percentage of participants |
| Arm II (Afatinib Dimaleate) | Response Rates | 74 percentage of participants |
Secondary
Time to Treatment Discontinuation
From date of registration to date of discontinuation of treatment or death due to any cause
Time frame: up to 3 years post-registration
Population: Eligible participants who were randomized to study arms.
| Arm | Measure | Value (MEDIAN) |
|---|---|---|
| Arm I (Afatinib Dimaleate, Cetuximab) | Time to Treatment Discontinuation | 12.7 months |
| Arm II (Afatinib Dimaleate) | Time to Treatment Discontinuation | 12.2 months |
p-value: 0.5495% CI: [0.64, 1.26]Log Rank
Secondary
Time to Treatment Failure
From date of registration to date of first documentation of progression or symptomatic deterioration, early discontinuation of treatment, or death due to any cause.
Time frame: assessed up to 3 years post registration
Population: Eligible participants who were randomized to study arms.
| Arm | Measure | Value (MEDIAN) |
|---|---|---|
| Arm I (Afatinib Dimaleate, Cetuximab) | Time to Treatment Failure | 10.8 months |

p-value: 0.9595% CI: [0.73, 1.39]Log Rank
Other Pre-specified
Change in Copy Number Alterations in MET, EGFR, and HER2, Analyzed Using Fluorescence in Situ Hybridization
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.
Time frame: Baseline up to 3 years (after disease progression)
Other Pre-specified
Change in the Ratio of Sensitizing EGFR Mutation to EGFR T790 Mutation
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.
Time frame: Baseline up to 3 years (at progression)
Other Pre-specified
EGFR Immunohistochemistry H-score
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.
Time frame: Baseline
Other Pre-specified
Levels of Circulating Tumor Markers
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.
Time frame: Up to 3 years
Other Pre-specified
Presence of de Novo EGFR T790M Mutation or Other Molecular Alterations
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..
Time frame: Baseline
Other Pre-specified
Ratio of Sensitizing EGFR Mutation to EGFR T790 Mutation
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
Time frame: Up to 3 years
