Induction Chemotherapy Followed by CCRT According to EGFR Mutation Status in NSCLC III

Phase 2

• Conditions: Lung Cancer; NSCLC
• Interventions: Drug: Induction or consolidation IP chemotherapy; Drug: Erlotinib; Radiation: CCRT; Drug: CCRT with IP chemotherapy (Irinotecan + Cisplatin)

• Registration Number: NCT00620269
• Lead Sponsor: National Cancer Center, Korea

Brief Summary

The use of induction chemotherapy is feasible and effective. It is also logistically beneficial for decreasing micrometastases and radiation-related toxicity by decreasing tumor burden before definite locoregional concurrent therapy. Previously the investigators conducted several phase II study of IP chemotherapy in advanced NSCLC and demonstrated that IP chemotherapy has a promising activity and readily manageable toxicity profile. Given the encouraging activity of IP chemotherapy in the advanced stage setting, the investigators postulated that their further investigation in the stage III setting might lead to further prolongation of survival times. In addition to cisplatin, Irinotecan has been demonstrated to act as radiation sensitizers in preclinical and clinical setting. Therefore, their use with concurrent radiotherapy might lead to radiation sensitization and improved locoregional control.

Detailed Description

Concurrent Chemoradiation therapy is widely accepted as a standard treatment of locally advanced unresectable stage III NSCLC. When compared with the result of radiation therapy alone of CALGB 8433 trial (i.e., 9.7 months), the median survival times have almost doubled over the last 2 decades, but rarely exceeded 18 months after chemoradiation therapy in most randomized trials. On the other hand, a significant portion of patients had to endure the side effects of grade 3/4 esophagitis and also pneumonitis, which resulted in treatment-related deaths in some cases. There is a great need to develop more effective but less toxic treatment strategies. Recently, molecular-targeted therapy using EGFR-TKIs brought new enthusiasm to the NSCLC therapy. The investigators observed a median survival time of 20.1 months in chemo-naïve never-smoker Korean patients with adenocarcinoma of the lung. The benefit of EGFR-TKI was also demonstrated in never-smokers who participated in the phase III trial of carboplatin/paclitaxel with or without Erlotinib (TRIBUTE). Despite a lack of benefit in the overall patient population, Erlotinib conferred a survival benefit to those who had never smoked cigarettes, In this analysis, 105 patients who were identified as never smokers had a median survival of 10 months, similar to the entire study population, when treated with carboplatin/paclitaxel plus placebo. However, for the patients in this subpopulation who were treated with Erlotinib and the same chemotherapy regimen, the median survival increased to 22.5 months (P = 0.01). Furthermore, EGFR mutation was associated with significantly higher response rate and longer survival as compared with those without EGFR mutation. More importantly, the median survival time of those patients with EGFR mutation-positive tumors exceeded 20 months in the majority of the studies. These results are very provocative given the fact that only the patients with stage IIIb not amenable to chemoradiation therapy and stage IV NSCLC patients were included in the study and in many studies, the majority of the patients were heavily pre-treated with multiple chemotherapy regimens. The investigators postulate that if the case were properly selected, EGFR-TKI would significantly improve the overall survival of the patients with locally advanced unresectable stage III NSCLC. The investigators therefore propose a randomized phase II trial to evaluate the efficacy and toxicity of EGFR-TKI Erlotinib in selected group of NSCLC patients with EGFR mutation-positive stage III tumors. The use of induction chemotherapy is feasible and effective. It is also logistically beneficial for decreasing micrometastases and radiation-related toxicity by decreasing tumor burden before definite locoregional concurrent therapy. Previously the investigators conducted several phase II study of IP chemotherapy in advanced NSCLC and demonstrated that IP chemotherapy has a promising activity and readily manageable toxicity profile. Given the encouraging activity of IP chemotherapy in the advanced stage setting, the investigators postulated that their further investigation in the stage III setting might lead to further prolongation of survival times. In addition to cisplatin, Irinotecan has been demonstrated to act as radiation sensitizers in preclinical and clinical setting. Therefore, their use with concurrent radiotherapy might lead to radiation sensitization and improved locoregional control.
