First-Line Erlotinib Therapy and the Subsequent Development of Mechanisms of Secondary Resistance in Patients With Non-Small Cell Lung Cancer and Known Sensitizing EGFR Mutations

Erlotinib is a drug which targets non small cell lung cancer with a genetic change (mutation) in the epidermal growth factor receptor (EGFR). This drug has been used in other cancer research studies and information from those studies suggests that Erlotinib can control the growth of these cancer cells.

NCT00997334 Non-small Cell Lung Cancer
MeSH: Lung Neoplasms Carcinoma, Non-Small-Cell Lung
HPO: Neoplasm of the lung Non-small cell lung carcinoma

1 Interventions

Name: Erlotinib

Type: Drug

Erlotinib


Primary Outcomes

Description: Participants were classified into 4 potential resistant mechanism groups (4 genetic/ 1 histologic) based on evaluation of rebiopsy tissue: EGFR mutations (T790M mutation, exon 20 insertion), KRAS mutations, MET amplification or small-cell lung cancer (SCLC) transform using established methods.

Measure: Resistance Mechanism

Time: Participants were evaluated for incidence of genetic mechanisms of secondary resistance at time of disease progression at which point participants stopped treatment. Progression follow up was up to 3 years in this study cohort.

Secondary Outcomes

Description: Progression-free survival based on the Kaplan-Meier method is defined as the duration of time from study entry to documented disease progression (PD) or death. Per RECIST 1.1 criteria: progressive disease (PD) is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.

Measure: Progression-Free Survival

Time: Disease was evaluated radiologically every 8 weeks on treatment (cycle duration=4 weeks). Participants were treated until evidence of disease progression or unacceptable toxicity. Progression follow-up was up to 3 years in this study cohort.

Purpose: Treatment
