Study Description

Brief Summary

This study is designed as a single arm, un-controlled, open-label, multi-center hypothesis generating two-stage phase II trial. It is based on the assumption that the proposed treatment scheme doubles the rate of pathologic complete remission in Mutated epidermal growth factor receptor (EGFRmt) + NSCLC patients compared to historical control data from standard treatments.

Patients with NSCLC and activating EGFR mutation in stages II, IIIA and IIIB eligible for induction therapy with docetaxel and cisplatin and gefitinib

Patients will be treated for 12 days with gefitinib 250 mg/day p.o. (d -12 to -1) and induced with chemotherapy docetaxel 75 mg/m2 and cisplatin 50 mg/m2 d1+2 and intercalated gefitinib 250 mg/day d4-20 (cycle 1 and 2) and d4-17 (for cycle3). Surgery is planned in the 4th week after d1 of the last cycle.

Detailed Description

Based on the notion that neoadjuvant combination of Chemotherapy (CTx) and intercalated TKI is clinically beneficial, which can be inferred from prior study data and single case reports, this study aims to generate additional information on feasibility, safety and efficacy of this treatment approach in a larger group of EGFR mutated NSCLC patients. This study is a hypothesis generating two-stage trial for future phase III studies of neoadjuvant CTx with intercalated TKI. Hence, the study design relies entirely on a single treatment arm. To demonstrate efficacy it is sufficient to compare to historical data of the conventional treatments of NSCLC.

Outcome Measures

Primary Outcome Measures

pathologic complete remission rate (pCR rate) [12 weeks (after 3 cycles and surgery) after enrollment]
The primary objective of the study is to assess the pathologic complete remission rate after induction therapy with gefitinib d -12 to d-1 followed by docetaxel 75 mg/m2 and cisplatin 50 mg/m2 d1+2 q21 and intercalated gefitinib 250 mg d4 to d20 (cycle 1 and 2) and d4-17 (for cycle3), in order to demonstrate feasibility and efficacy of this treatment scheme. It is expected to achieve a pCR ≥30% regression grade IIB and III (Junker criteria) compared to historical controls in the mediastinal lymph nodes.

Secondary Outcome Measures

Adverse Events (AEs) / Serious adverse events (SAEs) [30 months]
AEs/SAEs from 21 patients during induction CTx with docetaxel and cisplatin in combination with intercalated gefitinib
Surgical R0 resection rate [30 month]
R0 resection rate as assessed according to the German S3 guidelines
Response: radiologic response based on CT [30 month]
progression free survival (PFS) [30 month]
Progression-free survival (PFS) will be defined as the time from enrollment to the time of disease progression or relapse or death, or to the date of last assessment without any such event (censored observation).
Overall survival (OS) [30 month]
The duration of overall survival (OS) will be determined by measuring the time interval from enrollment to the date of death or last observation (censored).
