Icotinib With Whole Brain Radiation Therapy in NSCLC Patients With Brain Metastases

A Single Center, Open Label, Multicenter Study to Determine the Safety and Efficacy of Icotinib in Combination With Whole Brain Radiation Therapy For NSCLC Patients With Brain Metastases

The purpose of this study is to evaluate the safety and efficacy of icotinib in combination with whole brain radiotherapy for NSCLC patients with brain metastases. The primary endpoint is objective response rate of intracranial lesions.

Non-small cell lung cancer (NSCLC) is one of the malignant tumors with the highest incidence of brain metastases. Patients with multiple brain metastasis showed poor prognosis and displayed an untreated median survival of only 3-6 months, and most patients died due to the progression of brain metastases. This study is designed to evaluate the safety and efficacy of icotinib combined with whole brain radiotherapy for NSCLC patients with brain metastases. The primary endpoint is intracranial objective response rate .

Inclusion Criteria:

• Histological or cytological confirmation of non-small-cell lung cancer (NSCLC).
• Diagnosis of non-systematic brain metastases on a Gadolinium-enhanced MRI. More than 2 sites of intracranial metastases, or the longest diameter of the intracranial lesion is more than 3cm.
• No other metastases except for brain metastases.

Exclusion Criteria:

• Previous usage of EGFR-TKI or antibody to EGFR: gefitinib, erlotinib, herceptin, erbitux.
• CSF or MRI findings consistent with metastases of spinal cord, meninges or meningeal.
