Granulocyte-colony Stimulating Factor (G-CSF) and Plerixafor Plus Sorafenib for Acute Myelogenous Leukemia (AML) With FLT3 Mutations
G-CSF and Plerixafor With Sorafenib for Acute Myelogenous Leukemia With FLT3 Mutations

The goal of this clinical research study is to learn the most tolerable dose of Nexavarâ (sorafenib) when given in combination with Mobozilâ (plerixafor) and Neupogenâ (filgrastim) to patients with AML. The safety of this combination will also be studied.

The Study Drugs:

Sorafenib is a type of drug called a multikinase inhibitor. It is designed to interfere with the parts of cancer cells that are involved in the sending of chemical messages and helping the cells divide and grow, which may block the formation of tumors and cause cell death.

Filgrastim promotes the growth of white blood cells, which help to fight infections.

Plerixafor is designed to help move stem cells from the bone marrow to the blood.

Study Drug Dose Level:

If you are found to be eligible to take part in this study, you will be assigned to a dose level and schedule of sorafenib based on when you joined this study. Up to 5 dose levels and schedules will be tested. Three (3) participants will be enrolled at each dose level for Phase I of the study. The first group of participants will receive dose level "0" of sorafenib. If unacceptable side effects are seen, a dose lower than level "0" will be tried. If no side effects are seen, the next group of 3 patients will be placed on a higher dose level, called Level "1." Each new group will either receive a higher or lower dose of sorafenib or take it more or less often than the group before it, based on whether intolerable side effects are seen. This will continue until the best tolerable dose and schedule of sorafenib is found. Once the best tolerable dose and/or schedule is found, the last 10 participants will be enrolled and will take sorafenib at that dose and schedule. This last group of 10 is considered the early Phase II part of the study.

Each group will receive the same dose level and schedule of filgrastim and plerixafor.

Study Drug Administration:

You will receive filgrastim and plerixafor by injection through a needle under the skin on Day 1 (the day the study starts) and then every other day for a total of 7 doses. The injections will be given in the morning. After day one, the injections may be done at your home. Your study doctor will meet with you one-on-one to discuss how the drug will be given.

On Day 1, you will begin taking your dose of sorafenib by mouth every other day, once a day, or twice a day, depending on when you join the study.

  • If you are taking sorafenib every other day, during Cycle 1 you will start taking it 12 hours after the filgrastim and plerixafor injections (the next morning) .
  • If you are taking sorafenib every day, you will take it at the same time every morning. The first time you take sorafenib during Cycle 1 will be 12 hours after the first filgrastim and plerixafor injections.
  • If you are taking sorafenib twice a day, during Cycle 1 you will start taking it 12 hours after the filgrastim and plerixafor injections and then every 12 hours.

You will take sorafenib without food, at least 1 hour before or 2 hours after eating. If you miss a dose, do not take double the dose next time to make up for the missed dose.

These 28 days are one "study cycle".

You are allowed to take hydroxyurea or other treatments to control high white blood cell counts.

Study Drug Diary:

You will be given a study drug diary that you will be expected to fill out whenever you take study drugs at home. A staff member will explain to you how to fill out the diary. The study staff will review the diary with you at every study visit and you will be given a new diary at the beginning of every cycle you start.

Study Visits:

Every week for the first 6 weeks and then every 4-8 weeks, the following tests and procedures will be performed:

  • You will have a physical exam, including measurement of your weight, and vital signs.
  • You will have a bone marrow aspiration and biopsy done before treatment starts and once somewhere between day 14 and day 17 after the first Sorafenib administration. Another bone marrow sample will be collected between days 24 and 28.
  • If you continue on study, another bone marrow sample will be collected after the third cycle.
  • Blood (about 1 teaspoon) will be drawn every 2-4 days for routine tests while you are taking the study drugs and once a week on days you are not taking the study drugs Plerixafor and Neupogen.
  • During the first week, blood (about 1 teaspoon) will be drawn to check the status of the disease before each dose of the filgrastim and plerixafor combination and again 4 to 8 hours after receiving the study drugs. If your doctor feels it is needed, additional blood may be drawn after the 2nd blood draw to check the status of the disease. If your doctor feels it is needed, these blood draws may continue after the first week if the disease is not responding.

Length of Study:

You may continue taking the study drugs for up to 6 cycles (about 6 months). If you are in complete remission, partial remission, or complete remission with incomplete platelet count recovery after 6 months with no intolerable side effects, your doctor may discuss continuing on the study with you. You will be taken off study if the disease gets worse or intolerable side effects occur.

End-of-Study Visit:

You will have an end-of-study visit about 30 days after your last dose of the study drugs. At this visit, the following tests and procedures will be performed:

  • You will have a physical exam, including measurement of your weight and vital signs.
  • Blood (about 2 tablespoons) will be drawn for routine tests.
  • You will have a bone marrow aspirate and biopsy to check the status of the disease.

This is an investigational study. Sorafenib is FDA-approved and commercially available for treatment of advanced renal cell cancer (RCC) and hepatocellular cancer (HCC) that cannot be removed by surgery. Its use in patients with AML is investigational.

Plerixafor is FDA-approved and commercially available for use in boosting the number of hematopoietic stem cells (HSC) for stem cell collection and transplants (in combination with filgrastim) in patients with non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM). Its use in patients with AML is investigational.

Filgrastim (NeupogenÒ) is FDA-approved and commercially available for use in boosting white blood cell production in patients with low blood cell counts caused by chemotherapy (nonmyeloid malignancies, acute myeloid leukemia, and bone marrow transplantation), treating severe chronic neutropenia (SCN-low blood counts), and boosting production of hematopoietic progenitor cells in patients undergoing peripheral blood progenitor cell (PBPC) collection.

Up to 28 patients will take part in this study. All will be enrolled at MD Anderson.
