Temsirolimus in Combination With Metformin in Patients With Advanced Cancers
Overview[ - collapse ][ - ]
| Purpose | The goal of this clinical research study is to find the highest tolerable dose of the combination of temsirolimus and metformin that can be given to patients with advanced cancer. The safety of the drug combination will also be studied. Temsirolimus is designed to block a protein called mTOR (a protein that is thought to cause cancer cells to grow) inside the cancer cell. This may interfere with the growth or spread of cancer cells or possibly kill them. Metformin was designed to treat patients with diabetes. It may be able to block the protein mTOR and slow the growth of tumors. |

| Detailed Description | Study Groups: If you are found to be eligible to take part in this study, you will be assigned to a dose level of temsirolimus and metformin based on when you join this study. Up to 6 dose levels of temsirolimus and metformin will be tested. Up to 6 participants will be enrolled at each dose level. The first group of participants will receive the lowest dose level. Each new group will receive a higher dose than the group before it, if no intolerable side effects were seen. This will continue until the highest tolerable dose of the combination of temsirolimus and metformin is found. Expansion Groups: When the highest tolerable dose of the study drug combination is found, there will be one group of up to 40 endometrial carcinoma patients enrolled in a tumor-specific expansion group. Study Drug Administration: The first study cycle is 42 days and each cycle after that is 28 days. Before you start taking both drugs in Cycle 1, you will take metformin only for the first 2 weeks. This is called a titration period. On Days 15, 22, 29 and 36 of Cycle 1, you will receive temsirolimus by vein over 30-60 minutes. For each cycle after that, you will receive temsirolimus by vein over 30-60 minutes on Days 1, 8, 15, and 22. Before you receive temsirolimus, you will receive Benadryl (diphenhydramine) by vein over 30-60 minutes to help lower the risk of allergic reactions. You will take metformin by mouth every day at about the same time each day with a meal and cup of water (about 8 ounces). You should take it at home except on the days when you have a study visit. On study visit days, you may take the metformin before you receive the temsirolimus. Depending on your dose, you may take metformin 1-3 times daily. Your study doctor will tell you how to take this drug. You will be given a letter to take to your home doctor(s) about your study drug administration as part of your care provided outside of MD Anderson. Study Visits: At every study visit, you will be asked about your health, any other drugs you are taking, and if you have had any side effects. Exams and tests will be performed before you receive the study drugs that day. Cycle 1 Day 1 tests and exams may not have to be repeated if done within 7 days. If you are part of the expansion group, within 7 days before Day 1 of Cycle 1: - Blood (about 2 teaspoons) will be drawn for pharmacodynamic (PD) testing. PD testing measures how the level of study drug in your body may affect the disease. - If you are part of the expansion group and have a certain mutation, you will have a biopsy for PD testing. The tumor biopsy will be collected using either a fine needle aspiration or a core biopsy, depending on the location and size of the tumor. To perform a core biopsy, a sample of tissue is removed using a hollow core needle that has a cutting edge. To collect a fine needle aspirate, a small amount of tissue is withdrawn through a needle. If you have questions about your mutation status, the doctor can discuss this with you. On Day 1 of Cycle 1 (titration period): - You will have a physical exam, including measurement of your weight and vital signs. - Your performance status will be recorded. - Blood (about 2 teaspoons) will be drawn for routine tests. - During Week 1 only, urine will be collected for routine tests. On Day 8 of Cycle 1 (titration period), blood (about 2 teaspoons) will be drawn for routine tests. On Day 15 and Day 29 of Cycle 1: - You will have a physical exam, including measurement of your weight and vital signs. - Your performance status will be recorded. - Blood (about 2 teaspoons) will be drawn for routine tests. - During Week 1 only, urine will be collected for routine tests. On Day 22 and Day 36 of Cycle 1, blood (about 2 teaspoons) will be drawn for routine tests. If you are part of the expansion group, on Day 37 of Cycle 1: - Blood (about 2 teaspoons) will be drawn for PD testing. - If you are part of the expansion group and have a certain mutation, you will have a biopsy for PD testing. On Day 1 of Cycles 2 and beyond: - You will have a physical exam, including measurement of your weight and vital signs. - Your performance status will be recorded. - Blood (about 2 teaspoons) and urine will be collected for routine tests. On Day 15 of Cycles 2 and beyond, blood (about 2 teaspoons) will be drawn for routine tests. About every 8 weeks, you will have an x-ray, CT scan, MRI scan, and/or PET/CT scan to check the status of the disease. If the study doctor thinks it is needed, they will be performed more often. After about 6 months (about 6 cycles) of taking the study drugs, you will have the CT scan or MRI scan every 2-4 cycles if your study doctor thinks it is needed. Length of Study Participation: 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 drug if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions. Your participation on the study will be over when you have completed the end-of-study visit. End-of-Study Visit: Within 30 days after your last dose of study drugs, you will return to the clinic. The following tests and procedures will be performed: - You will have a physical exam, including measurement of your weight and vital signs. - Your performance status will be recorded. - Blood (about 2 teaspoons) and urine will be collected for routine tests. If you are part of the expansion group, - Blood (about 2 teaspoons) will be drawn for PD testing if the disease gets worse. - If you are part of the expansion group and have a certain mutation, you will have a biopsy for PD testing if the disease gets worse. This is an investigational study. Temsirolimus is FDA approved and commercially available for the treatment of renal cell carcinoma. Metformin is FDA approved and commercially available for the treatment of diabetes mellitus. The combination of these drugs to treat advanced cancer is investigational. Up to 104 patients will take part in this study. All will be enrolled at MD Anderson. |
