TREND: Targeted Treatment With Intercalated Radiotherapy in EGFR-mutant IIIA/IIIB NSCLC
Study Details
Study Description
Brief Summary
The aim of this study is to investigate the efficacy and safety of intercalated combination of erlotinib and radiotherapy for patients with EGFR-mutant, unresectable, locally advanced NSCLC, and to explore a new treatment strategy for this subset. After Induction by erlotinib, local radiotherapy is intercalated, and followed by 24-week erlotinib maintenance.

Phase 2/Phase 3 |
Detailed Description
Chemoradiation therapy is the standard treatment for unresectable, locally advanced NSCLC, but its efficacy reaches a platform, and treatment-related life threatening toxicity limits its use. The EGFR tyrosine kinase inhibitors (TKIs) produce a dramatic response in patients carrying EGFR activating mutations in the metastatic setting. Multiple prospective trials show that EGFR-TKIs have a better tolerability when compared with chemotherapy.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: EGFR-mutant IIIA/IIIB NSCLC Erlotinib Hydrochloride 150mg daily intercalated with radiotherapy |
Drug: Erlotinib Hydrochloride
Subjects receive erlotinib tablet 150mg orally once daily, after 12 weeks of induction phase, local radiotherapy is intercalated, and followed by 24-week erlotinib maintenance phase. At the end of maintenance, the subjects enter into the follow-up period.

Outcome Measures
Primary Outcome Measures
- Objective response rate [Tumor response will be evaluated through study completion, an average of 6 weeks.]
assessed by the RECIST 1.1 criteria
Secondary Outcome Measures
- 1 year survival rate [Pts after maintenance phase will receive long-term follow-up including CT scan every 12 weeks for up to 10 years.]
To evaluate the 1 year survival rate of the new strategy.
- 3 year survival rate [Pts after maintenance phase will receive long-term follow-up including CT scan every 12 weeks for up to 10 years.]
To evaluate the 3 year survival rate of the new strategy.
- Progression free survival（PFS） [Occurrence of local or regional progression, distant metastases, or death from any cause from the time of treatment to the occurrence of one of the failure events, whichever occurs first, assessed up to 10 years.]
The product limit estimator developed by Kaplan and Meier will be used.
- Overall survival [Time from treatment to death from any cause, assessed up to 10 years.]
The product limit estimator developed by Kaplan and Meier will be used. Their 95% confidence intervals will be estimated.
Other Outcome Measures
- Quality of Life (QOL) [Questionnaire of QOL will be recorded for up to 24 weeks.]
To evaluate the Quality of Life (QOL) of subjects during treatment.
