High Dose Gefitinib for the Treatment of Carcinomatous Meningitis in Adult Patients With Non-Small Cell Lung Cancer and Known or Suspected EGFR Mutations
The primary purposes of this study are to find out if using high doses of the drug Gefitinib (Iressa) as a way to treat patients with non-small cell lung cancer that has spread to the covering of the brain and/or spinal cord (meninges) results in any bad side effects; and to determine the highest dose that can be given to patients in this setting.

|Official Title:||Phase I Study of High Dose Gefitinib (Iressa) for the Treatment of Carcinomatous Meningitis in Adult Patients With Non-Small Cell Lung Cancer and Known or Suspected EGFR Mutations|
- To assess the safety of administering gefitinib in doses of 750mg to 1250mg in adult patients with carcinomatous meningitis from non-small cell lung cancer with known or suspected somatic EGFR mutations. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
- To measure the cytologic response rate, response duration, time to neurologic progression, and survival following high dose gefitinib therapy administered on this schedule [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- to measure gefitinib levels with serum and cerebrospinal fluid while on therapy, and to correlate these levels with toxicity, response and survival [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
- to examine archived tumors for the presence or absence of EGFR mutations and resistance mutations, and to correlate those mutations with cytologic response, time to neurologic progression, and survival. [ Time Frame: 2 years ] [ Designated as safety issue: No ]

- The standard therapy for this type of cancer is to give chemotherapy directly into the spinal fluid, usually by a spinal tap. Some chemotherapy may, in some cases, be combined with radiation. This study looks at a different way of treating this type of cancer.
- This study is specifically for patients whose lung cancer has changes in a protein called the epidermal growth factor receptor (EGFR). The study drug, gefitinib, was developed to stop the signals from the EGFR that tell certain types of lung cancers tumors to grow. By using higher doses than are normally used, we hope to increase the amount of drug in the spinal fluid to attempt to kill the cancer cells around the spinal cord and brain.
- Since we are looking for the highest dose of gefitinib that can be given safely, not everyone who participates in this study will be receiving the same amount of drug.
- Patients will start taking gefitinib daily by mouth on Day 1 and will continue taking this medication daily at home. On the first day the patient takes gefitinib and on Day 14 of each treatment cycle (1 cycle equals 28 days), the patient will undergo: Physical examination by the study doctor and a detailed neurological exam by a neuro-oncologist; sampling of cerebrospinal fluid (CSF) by lumbar puncture; review of current medications; measurement of vital signs; check on the patients ability to perform daily activities; blood work.
- If the patient is tolerating the study medication well, then the patient will receive a lower dose for days 15-28 of the cycle.
- At the end of each cycle on Day 28, the patient will meet with the study doctor and have the following: a physical examination; review of current medications; measurement of vital signs, check on the patients ability to perform daily activities; blood tests; MRI of the brain and spinal cord to assess tumor response; every two cycles a CT scan of the chest and abdomen to assess the tumor response.
