Ipilimumab + Temozolomide in Metastatic Melanoma

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical research study is to learn if combining ipilimumab and temozolomide can help to control metastatic melanoma. The safety of this drug combination will be studied. Researchers would also like to study how this therapy affects the levels of certain chemicals in the blood that are related to your immune system.

Detailed Description
-----------------
The ability to control melanoma depends on how well your immune system recognizes and then attacks cancer cells. Researchers want to use ipilimumab to try to trigger your immune system response, while temozolomide is designed to damage the cancer cells themselves. Study Drugs: Ipilimumab is designed to block the activity of cells that lower the immune system's ability to fight cancer. Blocking these cells may help the body's immune system fight the cancer cells better. Temozolomide is designed to stop cancer cells from making new DNA (the genetic material of cells). If they cannot make DNA, then they cannot divide into new cancer cells. Study Drug Administration: If you are found to be eligible to take part in this study, you will begin to receive treatment with ipilimumab plus temozolomide. You will have an intravenous (IV) catheter placed into a large vein for the Ipilimumab. There are 2 phases of study drug treatment: Induction and Maintenance. During the Induction Phase, you will receive ipilimumab by vein over 90 minutes on Day 1 of each 3-week Induction course. You will take temozolomide by mouth in tablet form on Days 1-4 of each course. You will receive up to 4 courses of Induction therapy. During the Maintenance Phase, you will receive ipilimumab by vein over 90 minutes on Day 1 every 12 weeks. You will also take temozolomide by mouth for 5 days in a row, every 4 weeks. You may take the Temozolomide dose within 48 hours of receiving the Ipilimumab dose on Day 1 of both the Induction and the Maintenance Phase. You will see your doctor before each new course (every 3 weeks) during the Induction Phase, and once every 4 weeks during the Maintenance Phase. All treatments will be given in the outpatient clinic. You will be given anti-nausea medication to decrease the risk of nausea and vomiting, as needed. Study Tests: Before Each Course: (Every 3 weeks during Induction, and every 4 weeks during Maintenance) Blood (about 1 teaspoon) will be drawn for routine tests and tests of your liver and kidney function. You will be asked about any medication you are taking and any side effects you are experiencing. Women who are able to become pregnant will have a blood (about 1 teaspoon) or urine pregnancy test. Your performance status will be recorded. Your vital signs will be measured on Day 1. Every week, blood (about 1 teaspoon) will be drawn for routine tests. At the end of each course, any tumor that can be felt with the hands will be measured during physical exam to see if it is shrinking. Every 2 courses (+/- 7 days), you will have a chest x-ray and CT or MRI scans performed to check the status of the disease. Length of Study: You may continue taking the study drugs for as long as the doctor thinks it is in your best interest. You will no longer be able to take the study drugs if the disease gets worse or intolerable side effects occur. If you stop receiving the study drugs for any reason, you will have an End-of-Treatment Visit. End-of-Treatment Visit: Within 14 days after you stop study treatment, you will come into the clinic for the End-of-Treatment Visit. At this visit, the following tests will be performed: You will have a physical exam, including a measurement of your vital signs and weight. You will be asked about any other medications you are taking or any side effects you are experiencing. Blood (about 2 tablespoons) will be drawn for routine tests. Your may have a CT or MRI scan performed to check for side effects. Every 2 months for up to 3 years, you will also be contacted by telephone or during a clinic visit to see how you are doing. This is an investigational study. At this time, temozolomide is FDA approved and commercially available for the treatment of primary brain cancer. However, the use of temozolomide in treating metastatic melanoma is considered investigational. At this time, ipilimumab is being used in research only. The use of these drugs together is also considered investigational. Up to 64 patients will take part in this study. All will be enrolled at MD Anderson.

Eligibility Criteria
-----------------
Inclusion Criteria: Patients with histologically documented diagnosis of advanced/inoperable metastatic melanoma of skin or mucosal origin are eligible, provided they fulfill the following conditions: They are 18 years old to 75 years old with measurable (at least 1 cm) metastatic disease. They have Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Must be at least 21 days since surgery, radiation therapy and 6 weeks after immunotherapy with regimens including vaccine, interferon, IL-2 etc. and fully recovered from adverse effects of these therapies. Must agree not use vaccines for the treatment of cancer or prevention of disease unless indicated as a component of the protocol regimen (including those for common medical conditions) for up to one month pre and post dosing with ipilimumab. Required values for initial laboratory tests: white blood cell count (WBC): 2000/uL or greater, absolute neutrophil count (ANC): 1000/uL or greater, Platelets: 100 x 103/uL or greater, Hemoglobin: 9 g/dL or greater, Creatinine: </=1.5 mg/dL, AST and ALT: </= 2.5 x upper limit of normal (ULN) for subjects without liver metastasis or, </= 5 X upper limit of normal (UNL) for liver metastases, Bilirubin: </= 1.5 mg/dL, LDH </= 2 X upper limit of normal (UNL). They have no significant intercurrent illness such as a serious infection which requires intravenous antibiotics. No active or chronic infection with HIV, Hepatitis B, or Hepatitis C.
