Spots Global Cancer Trial Database for Gemox as First and Second Line Therapy in Unknown Primary Cancer

Study Description

Brief Summary: Primary objectives: 1. To determine the overall tumor response rate with oxaliplatin in combination with gemcitabine (GEMOX) as first line and second line therapy in unknown primary cancer (UPC). 2. To determine the tolerability (toxicity) of this regimen in this patient population. Secondary objectives: 1. To determine the median overall survival (OS) and time to progression (TTP) for patients treated with this combination. 2. To determine the impact of this combination on quality of life (QOL) in this patient population.

Detailed Description: Oxaliplatin is a chemotherapy drug that causes the death of cancer cells and other actively dividing cells by interfering with Deoxyribonucleic acid (DNA) function. Gemcitabine prevents cells from making DNA and Ribonucleic acid (RNA) that are necessary for cell growth, thus disrupting the growth of the cancer cells, which causes the cancer cells to start to die. After the screening portion of the study, if you are eligible to begin study treatment, you will come to M. D. Anderson at least every two weeks (14 days) for treatment. Each 14-day period of treatment is called a "cycle" of therapy. You will receive at least 3 cycles of therapy (6 weeks) unless side effects become intolerable or the disease progresses. When you begin treatment, you will have a small tube (central venous line) inserted into a large vein under the skin of the chest or through a vein in the arm for administration of oxaliplatin and gemcitabine. The central venous line will remain in place the entire time you are taking part in this study. Both drugs must be given at M. D. Anderson. On Day 1 of each cycle, you will receive gemcitabine injected into a vein over 2 hours. On Day 2 of each cycle you will receive oxaliplatin injected into a vein over 2 hours. This drug schedule will be repeated every 2 weeks. You will first be asked to fill out several questionnaires that deal with your quality of life. These will help the researchers understand how the study drugs affect your quality of life including your pain level, fatigue (tiredness) level, appetite, and ability to perform everyday tasks, in spite of whether there is any shrinkage of the tumor. It will take about 30 minutes to an hour to complete the forms. You will also be asked to complete a questionnaire (one time only) that asks questions about why you decided to take part in this study. During the first cycle of therapy, blood (about 2 1/2 teaspoons) will be collected once a week for routine tests. Before each new cycle of therapy, you will have a complete physical exam, urine will be collected, and blood will be drawn (about 2 ½ teaspoons) for routine tests. You will be asked to tell the study doctor about all medications you have taken since you started taking the study drugs and any health problems that you may have experienced. You will also have either computed tomography (CT) scans or an Magnetic resonance imaging (MRI) of the tumor(s) every 6 weeks and at the end of the study. All tests before each new cycle of treatment and when treatment stops must be done at M. D. Anderson. Extra tests may be done during the study if your doctor feels it is necessary for your care. Every 6 weeks for as long as you are on study, you will also be asked to fill out the questionnaires that help study doctors understand your quality of life. It will take about 30 minutes to an hour to complete the forms. If you experience intolerable side effects, treatment may be delayed, stopped, or you may receive smaller doses of the treatment. You may continue to receive treatment on this study, unless the disease gets worse or you experience any intolerable side effects. If this happens, you will be taken off the study and your doctor will discuss other treatment options with you. When you stop taking part in the study for any reason, you will have blood (about 3 teaspoons) collected for final routine tests. You will have one more physical exam and either a CT scan or a MRI to check on the status of the disease. You will also be asked once more to fill out the questionnaires that help assess your quality of life. It will take about 30 minutes to an hour to complete the forms. Once you stop receiving study treatment, you will be contacted by phone every three months for the rest of your life to check on how you are doing and any symptoms you may be experiencing. This is an investigational study. Oxaliplatin is FDA approved for treatment of advanced cancer of the colon or rectum, and gemcitabine is FDA approved for the treatment of advanced cancer of the pancreas. However, the combination of the two drugs for treatment of cancers with unknown primaries is still considered investigational. Up to 81 people will take part in this study. All will be enrolled at M. D. Anderson.
