Official Title  ICMJE Phase I/II, Dose-Escalation Study of Ponatinib, a FLT3 Inhibitor, With and Without Combination of 5-Azacytidine, in Patients With FLT3-Mutated Acute Myeloid Leukemia (AML)
Brief Summary

The goal of Part 1 of this clinical research study is to learn if ponatinib alone can help to control FLT3-mutated AML or FLT3-mutated high-risk MDS. The safety of this drug will also be studied.

The goal of Part 2 of this clinical research study is to find the highest tolerable dose of ponatinib in combination with 5-azacytidine and to learn if the highest dose level found can help to control FLT3-mutated AML or FLT3-mutated high-risk MDS. The safety of this combination will also be studied.

Detailed Description

Study Groups:

If participant is found to be eligible to take part in this study, they will be assigned to either Part 1 or Part 2 based on when they join this study.

If participant is enrolled in Part 1, they will receive ponatinib alone for the first cycle. If the doctor thinks it is needed, the dose level may be increased. If the disease does not respond to ponatinib alone, participant will continue on to Part 2 of this study.

Part 2 of this clinical research study will have 2 phases: Phase 1 (dose escalation) and Phase 2 (dose expansion).

In Part 2, participant will be assigned to a study group based on when they join this study. Up to 3 groups of 30 participants will be enrolled in Phase 1 of Part 2, and up to 60 participants will be enrolled in Phase 2.

If participant is enrolled in Phase 1, the dose of ponatinib they receive will depend on when they join this study. The first group of participants will receive the lowest dose level of ponatinib. Each new group will receive a higher dose of ponatinib than the group before it, if no intolerable side effects were seen. This will continue until the highest tolerable dose of ponatinib is found.

If participant is enrolled in Phase 2, they will receive ponatinib at the highest dose that was tolerated in Phase 1.

All participants in Part 2 will receive the same dose level of 5-azacytidine.

Study Drug Administration:

Each study cycle is 28 days.

Participant will take ponatinib tablets by mouth 1 time every day while they are on study. Participant should swallow the tablets whole. Participant should not crush them.

If participant is enrolled in Part 2, they will receive 5-azacytidine either by vein over about 1 hour or as an injection under the skin on Days 1-7 of each study cycle or on Days 1-5, 8, and 9 of each study cycle (if the clinic is closed on a weekend).

If the doctor thinks it is needed, the dose level, dosing schedule, or study cycle may be changed and/or delayed. The study doctor will discuss any changes with participant.

Study Visits:

On Day 1 of each cycle (+/- 4 days), participant will have a physical exam.

On Day 1 (+/-1 day) of Cycles 1-3 and then every 3 cycles after that (Cycles 6, 9, 12, and so on), participant will have an EKG.

On Day 1 of Cycle 2 and then every 3 cycles after that, participant will have an ECHO or MUGA performed.

One (1) time each week during Cycles 1-3 and then 1 time every 2-4 weeks after that, blood (about 1 tablespoon) will be drawn for routine tests. Participant may be able to have these blood draws performed at a local lab or clinic that is closer to their home. The results of the testing will be sent to MD Anderson for review.

On Day 28 (+/- 7 days) of Cycles 1, 3, and then every 1-3 cycles after that, participant will have a bone marrow aspiration/biopsy to check the status of the disease.

One (1) time every 3 cycles, if participant can become pregnant, blood (about 1-2 tablespoons) will be drawn for a pregnancy test.

At any time while participant is on study, if the doctor thinks it is needed:

  • Blood (about 1-2 tablespoons) will be drawn for routine tests.
  • Participant may have a bone marrow aspiration/biopsy to check the status of the disease.

Length of Study:

Participant will receive ponatinib alone or ponatinib and 5-azacytidine for as long as the doctor thinks it is in their best interest. Participant will no longer be able to take the study drugs if the disease gets worse, if intolerable side effects occur, or if they are unable to follow study directions.

Patient's participation on the study will be over after the follow-up visits.

End-of-Study Visit:

Within 14 days after participant's last dose of study drug(s):

  • Participant will have a physical exam.
  • Blood (about 2-3 tablespoons) will be drawn for routine tests.
  • If the doctor thinks it is needed, participant will have a bone marrow aspirate/biopsy to check the status of the disease.

Follow-Up:

About 30 days after the end-of-study visit, a member of the study staff will call participant to ask if they have had any side effects and/or started any new treatment(s). This call should last about 5 minutes. If the study staff thinks it is needed, participant may also be asked to come into the clinic for a physical exam.

Long-Term Follow-Up:

If the disease appears to be responding to the study drugs, a member of the study staff will call participant every 3-6 months for up to 5 years to ask how they are doing and about any side effects they may be having. Each call should last about 5 minutes. Participant may also be asked to come into the clinic for a physical exam, if the study staff thinks it is needed.

This is an investigational study. 5-azacytidine is FDA approved and commercially available for the treatment of myelodysplastic syndrome (MDS). Ponatinib is commercially available and FDA approved for the treatment of specific groups of chronic myeloid leukemia (CML) participants. Their use in this study is considered investigational. The study doctor can explain how the study drugs are designed to work.

Up to 132 participants will take part in this study. All will be enrolled at MD Anderson.

  7. Patients must provide written informed consent.
  8. In the absence of rapidly progressing disease, the interval from prior treatment to time of initiation of ponatinib administration will be at least 2 weeks for cytotoxic agents OR at least 5 half-lives for cytotoxic/non-cytotoxic agents. Use of one dose of cytarabine (up to 2 g/m2) or hydroxyurea for patients with rapidly proliferative disease is allowed before the start of study therapy and for the first eight weeks on study therapy from the day of enrollment, either prior to or concomitantly with ponatinib administration initially to control the peripheral blast count. Concurrent therapy for central nervous system (CNS) prophylaxis or continuation of therapy for controlled CNS disease is permitted. Controlled CNS leukemia is defined by the absence of active clinical signs of CNS disease and no evidence of CNS leukemia on the most recent 2 simultaneous cerebrospinal fluid (CSF) evaluations.
  9. Women of childbearing potential must practice contraception. Females of childbearing potential: Recommendation is for 2 effective contraceptive methods during the study. Adequate forms of contraception are double barrier methods (condoms with spermicidal jelly or foam and diaphragm with spermicidal jelly or foam), oral, depo provera, or injectable contraceptives, intrauterine devices, and tubal ligation. Male patients with female partners who are of childbearing potential: Recommendation is for male and partner to use at least 2 effective contraceptive methods, as described above, during the study.

  11. Women of childbearing potential must agree to use an adequate method of contraception during the study and until 3 months after the last treatment. Males must be surgically or biologically sterile or agree to use an adequate method of contraception during the study until 3 months after the last treatment. Adequate methods of contraception include: (A) Total abstinence when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. (B) Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
  12. 11 (Cont'd): (C) Male sterilization (at least 6 months prior to screening). For female patients on the study, the vasectomized male partner should be the sole partner for that patient (D) Combination of any of the two following (a+b or a+c or b+c): (1) Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception (B) Placement of an intrauterine device (IUD) or intrauterine system (IUS). (C) Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal suppository In case of use of oral contraception, women should have been stable on the same pill before taking study treatment. Note: Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception due to unknown effect of drug-drug interaction.
  13. 11 (Cont'd) Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago.
