Stereotactic Body Radiation Therapy (SBRT) in Newly Diagnosed Advanced Staged Lung Adenocarcinoma (Sindas)
Study Details
Study Description
Brief Summary
To tested if the adding of consolidative SBRT to TKI in EGFR mutated patients with less than or equal to 5 metastatic sites (primary + 5) will improve progression free survival (PFS) compared to TKI alone.

Phase 3 |
Detailed Description
This protocol is a randomized phase III trial of TKI versus consolidative Stereotactic Body Radiation Therapy (SBRT) plus TKI for patients with Stage IV non-small cell lung cancer (NSCLC).
Prior to accrual on the trial, patients with Stage IV NSCLC will be tested with positive EGFR mutation. Patients who with fewer than or equal to 5 sites of oligometastatic disease will be randomized toTKI or consolidative SBRT to all sites of disease (followed by TKI at the medical oncologist's discretion). Choices of TKI will be determined by the medical oncologist based on clinical appropriateness.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: TKI without SBRT Newly diagnosed Patients will be placed on EGFR-TKI, ,Gefitinib 250mg po qd or Tarceva 150mg po qd for their metastatic EGFR-mutant stage IV oligometastatic disease. The oligometastatic disease will not receive SBRT |
Drug: TKI (Gefitinib or Tarceva )
A first line TKI (Gefitinib 250mg po qd or Tarceva 150mg po qd ) will be administered according to the standard dosing of the drug for metastatic NSCL, no local therapy apply to oligo-metastatic sites.
|
| Experimental: TKI with SBRT experimental: Oligometastatic Non-Small Cell Lung Cancer Newly diagnosed patients will be placed on EGFR-TKI, Gefitinib 250mg po qd or Tarceva 150mg po qd, for their metastatic EGFR-mutant stage IV oligometastatic disease. All patients will TKI, Gefitinib 250mg po qd or Tarceva 150mg po qd, and SBRT at the same time. SBRT to up to 5 sites. The SBRT dose range from 5 Gy per fraction to 8 Gy per fraction. SBRT deliver within 5 fractions. |
Radiation: Radiation: SBRT
A first line TKI (Gefitinib 250mg po qd or Tarceva 150mg po qd ) will be administered according to the standard dosing of the drug for metastatic NSCL during a 1-week run-in period after which SBRT will be delivered to the all oligometastatic lesions concurrently with the TKI. The SBRT dose will be , ranging from at 25Gy (5 Gy per fraction) to 40 Gy (8 Gy per fraction).
Drug: TKI (Gefitinib or Tarceva )
A first line TKI (Gefitinib 250mg po qd or Tarceva 150mg po qd ) will be administered according to the standard dosing of the drug for metastatic NSCL, no local therapy apply to oligo-metastatic sites.

Outcome Measures
Primary Outcome Measures
- Progression free survival [4 years]
Evaluate the effect of TKI with or without SBRT on progression free survival,to describe local control and out-of-field disease progression
Secondary Outcome Measures
- Overall survival [4 years]
To evaluate overall survival after SBRT followed by maintenance chemotherapy in comparison to maintenance chemotherapy alone.
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]) [4 years]
Using CTCAE system to evaluate toxicity profile
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Newly diagnosed metastatic lung adenocarcinoma (recurrent or de novo) harboring sensitizing EGFR mutations (L858R, exon 19 deletion, G719A, L861Q, S768I, exon 19 insertions) with oligometastatic disease (≤5 discrete lesions of disease irrespective of location, inclusive of the primary lesion):
-
all sites of disease must be amenable to definitive treatment with a local therapy (surgical resection, stereotactic radiosurgery, ablation and conventional radiation therapy) as determined by surgery, interventional radiology and radiation oncology
-
all intrathoracic lymph nodes (including hilar, mediastinal, and supraclavicular nodal disease) are considered 1 discrete lesion.
-
No brain metastasis is allowed.
-
Patients already started on erlotinib are eligible as long as their sites of disease are determined to be eligible for definitive local therapy by consensus of the principal investigators within 12 weeks of the patient first taking erlotinib.
