Clinical Trial 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.

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.

Eligibility

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.
• Lung adenocarcinoma histology confirmed
• Karnofsky Performance Status = 70%
• Adequate bone marrow, liver and renal function, as specified below:
• Absolute Neutrophil Count (ANC) = 1.5 x 109/L
• Hemoglobin = 8 g/dL
• Platelets = 100 x 109/L
• Serum total bilirubin = 1.5 x upper limit of normal (ULN) (except for patients with documented Gilbert's Syndrome)
• AST and ALT = 2.5 x ULN or = 5 x ULN if liver metastases are present
• Serum creatinine = 1.5 x upper limit of normal or creatinine clearance = 60ml/min for patients with creatinine levels above institutional normal.
• For women of child-bearing potential, negative pregnancy test within 14 days prior to starting treatment
• Men and women of childbearing age must be willing to use effective contraception while on treatment and for at least 3 months thereafter

Exclusion Criteria:

• Treatment with TKI prior to developing metastatic disease
• Malignant pleural effusion or pleural disease
• Leptomeningeal disease or brain metastasis.
• Any site of disease that is not amenable to definitively local therapy including surgery or radiation therapy
• Women who are breastfeeding or pregnant
• Concurrent malignancies other than non-melanoma skin cancer that require active ongoing treatment.
• Any medical co-morbidities that would preclude surgery or radiation therapy

Intervention

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.
