About
This clinical research study is made up of 3 phases: a Pilot Phase, Phase 1, and Phase 2.
The goal of the Pilot Phase is to learn how safe it is to give the study drug brentuximab vedotin to patients with AML. The goal of Phase 1 is to learn more about the safety of the combination of brentuximab vedotin with azacytidine. The goal of Phase 2 is to learn if the combination of brentuximab vedotin and azacytidine can help to control AML.
Full description
Study Groups:
If you are found to be eligible to take part in this study, you will be assigned to a study group based on when you join this study. Up to 3 groups of 3-6 participants will be enrolled in the Pilot Phase, up to 3 groups of 3-6 participants will be enrolled in Phase I of the study, and up to 25 participants will be enrolled in Phase II.
If you are enrolled in the Pilot Phase, the dose of brentuximab vedotin you receive will depend on when you joined this study. The first group of participants will receive the highest dose level of brentuximab vedotin. If intolerable side effects are seen, up to 2 more groups will be enrolled and will receive a lower dose of brentuximab vedotin than the group before it. If intolerable side effects are not seen, the next phase of the study will begin.
If you are enrolled in Phase I, the dose of brentuximab vedotin you receive will depend on when you joined this study. The first group of participants will receive a lower dose level of brentuximab vedotin than the highest one that was tolerated in the Pilot Phase, and will also receive azacitidine. If intolerable side effects are seen, up to 2 more groups will be enrolled and will receive a lower dose of brentuximab vedotin than the group before it. If intolerable side effects are not seen, the next phase of the study will begin.
If you are enrolled in Phase 2, you will receive brentuximab vedotin at the highest dose that was tolerated in Phase 1.
All participants in Phases 1 and 2 will receive the same dose level of azacytidine.
Study Drug Administration:
If you are found to be eligible to take part in this study, you will receive brentuximab vedotin by vein over 30 minutes on Days 1, 8, and 15 of each 28-day study cycle. If the disease appears to get better, or after cycle 4, the dose and schedule of brentuximab vedotin may be changed to monthly rather than weekly doses.
If you are in Phase 1 or Phase 2, you will also receive azacytidine by vein or as an injection under the skin on Days 1-7 of each cycle.
You may be given standard drugs to help decrease the risk of side effects. You may ask the study staff for information about how the drugs are given and their risks.
Study Visits:
On Day 1 of each cycle:
- You will have a physical exam.
- Blood (about 2-3 tablespoons) will be drawn for routine tests.
- You will have an EKG.
- Every 3 Cycles (Cycles 3, 6, 9, and so on), if you can become pregnant, blood (about 1 teaspoon) or urine will be collected for a pregnancy test.
On Days 8 and 22 of Cycle 1, blood (about 2-3 tablespoons) will be drawn for routine tests.
On Day 15 of Cycle 1:
- You will have a physical exam.
- Blood (about 2-3 tablespoons) will be drawn for routine tests.
On Day 28 of Cycle 1, then Day 1 of every 2 cycles after that (Cycles 3, 5, 7, and so on), you will have a bone marrow biopsy and/or aspirate to check the status of the disease. After any point that the disease appears to get better, this will be done every 3-4 cycles, or whenever your doctor thinks it is needed.
Length of Treatment:
You may receive the study drug for up to 12 cycles. You will no longer be able to receive the study drug(s) 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 after the end-of-study visit.
End-of-Study Visit:
About 28 days after your last dose of study drug, you will have an end-of-study visit:
- You will have a physical exam.
- Blood (about 2-3 tablespoons) will be drawn for routine tests.
- You will have an EKG to check your heart function.
- You may have a bone marrow biopsy and/or aspirate to check the status of the disease.
- If you can become pregnant, blood (about 1 teaspoon) or urine will be collected for a pregnancy test.
If the End-of-Study Visit occurs within 21 days of your last dose, you will be called by a member of the study team about 30-37 days after your last dose of study drug. You will be asked how you are feeling and about any side effects you may be having. This call will last about 5 minutes.
This is an investigational study. Brentuximab vedotin is FDA approved and commercially available for the treatment of certain types of lymphoma after previous treatments have failed. Its use in combination with azacitidine is investigational. Azacytidine is FDA approved and commercially available for the treatment of myelodysplastic syndrome (MDS) and chronic myelomonocytic leukemia (CMML).
The study doctor can explain how the study drug(s) are designed to work.
Up to 61 patients will take part in this study. All will be enrolled at MD Anderson.

Inclusion criteria
- Histologically or cytologically confirmed AML, other than acute promyelocytic leukemia, as defined by the 2008 World Health Organization (WHO) criteria that is relapsed or refractory to standard chemotherapy. Note: Newly-diagnosed AML patients who are 60 years or older and are not candidates for or have refused standard chemotherapy are also eligible for this trial.
- AML blasts must express CD30 (>/=10% expression as assessed by flow-cytometry or 2+ expression by immunohistochemistry) (whenever possible CD30 expression will be assessed by both methods)
- Age 18 years or older

- The following baseline laboratory data: Serum bilirubin </=1.5 x upper limit of normal (ULN) or </= 3 x ULN for patients with Gilbert's disease; Serum creatinine </=1.5 x ULN AND creatinine clearance >30 ml/min; Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) </=3 x ULN
- Females of childbearing potential must have a negative serum or urine beta human chorionic gonadotrophin (beta-hCG) pregnancy test result within 14 days prior to the first dose of brentuximab vedotin and must agree to use an effective contraception method during the study and for 30 days following the last dose of study drug.
