A Randomized Open-Label Phase II Trial of Pemetrexed and a Platinum (Carboplatin or Cisplatin) With or Without Erlotinib in Patients With Non-Small Cell Lung Cancer Harboring Activating Epidermal Growth Factor Receptor Mutations and Acquired Resistance to First-Line EGFR TKIs, Erlotinib or Gefitinib

This randomized phase II trial studies how well pemetrexed disodium and carboplatin or cisplatin with or without erlotinib hydrochloride work in treating patients with epidermal growth factor receptor (EGFR) mutant positive stage IV non-small cell lung cancer and acquired resistance to first-line therapy with erlotinib hydrochloride or gefitinib. In patients that develop resistance to first-line therapy with EGFR tyrosine kinase inhibitors (TKIs) the drug is usually stopped and the patient is switched to chemotherapy. Drugs used in chemotherapy, such as pemetrexed disodium, carboplatin, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether pemetrexed disodium and carboplatin or cisplatin is more effective with or without erlotinib hydrochloride in treating patients with EGFR mutant non-small cell lung cancer and acquired resistance to EGFR TKIs.

Primary Outcomes

Description: The Kaplan-Meier approach will be used to estimate the time-to-PFS distribution (and median PFS times) for each treatment arm. The stratified log-rank test will be used to compare the PFS distributions between the two treatment arms. The stratified Cox-regression model will be used to estimate the hazard ratio (erlotinib plus chemotherapy vs chemotherapy alone) and corresponding 80% confidence interval (CI).

Measure: Progression free survival using the Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1

Time: From randomization to the first occurrence of disease progression or death from any cause, whichever occurs earlier, assessed up to 1 year

Secondary Outcomes

Description: The Kaplan-Meier approach will be used. The stratified log-rank test will be used to compare the Overall Survival (OS) distributions between the two treatment arms. The stratified Cox-regression model will be used to estimate the hazard ratio (erlotinib plus chemotherapy vs chemotherapy alone) and corresponding 80% confidence interval (CI).

Measure: Overall survival

Time: From the date of randomization to the date of death from any cause, assessed up to 1 year

Description: An estimate of the objective response rate and its 95% CI (Blyth-Still-Casella) will be calculated for each treatment arm. The Mantel-Haenszel chi-squared test stratified according to the factors specified by EGFR activating mutation type (exon 19 deletion vs. exon 21 single point mutation), time to progression on first-line EGFR TKI (≤ 1 year vs. > 1 year), and ECOG performance status (0 vs. 1) will be used to compare the response rates between the two treatment arms. An unadjusted Fisher's exact test result will also be provided.

Measure: Objective response rate defined as partial response (PR) and complete response (CR) using RECIST version 1.1

Time: Up to 1 year

Description: Safety will be assessed through summaries of Adverse Events (AEs), Serious Adverse Events (SAEs), deaths, grade 3 or 4 AEs, AEs with incidence rates greater than 10% (all grades), AE of grade 3 or 4 with incidence rates greater 2%, and changes in laboratory test results. Verbatim descriptions of AEs will be mapped to Medical Dictionary for Regulatory Activities (MedDRA) thesaurus terms

Measure: Number of patients with each worst grade toxicity grades 3-5 based on the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4

Time: Up to 45 days post-treatment

Purpose: Treatment

Allocation: Randomized
