Clinical Trial Summary

The goal of this clinical research study is to learn if 5-aza-2 deoxycytidine (decitabine) given in combination with Mylotarg (gemtuzumab ozogamicin) can help to control Acute myeloid leukemia (AML), high-risk myelodysplastic syndromes (MDS) or Myelofibrosis (MF). The safety of this drug combination will also be studied.

Description:

The Study Drugs:

Gemtuzumab ozogamicin is designed to attach to Sialic acid-binding Ig-like lectin 3 (CD33), a certain protein that is often found in leukemia cells, causing them to die.

Decitabine is designed to damage the Deoxyribonucleic acid (DNA) (the genetic material) of cells, which may cause cancer cells to die.

Study Drug Administration:

If you are found to be eligible to take part in this study, you will receive decitabine through a needle in your vein over 1 and 1/2 hours on Days 1-5 of each cycle. You will also receive gemtuzumab ozogamicin by vein over about 1 hour after you receive decitabine on Day 5 of each 4-8 week cycle.

During Cycle 1 only, if a bone marrow test done 2 weeks after you receive your first study drug treatment shows abnormal leukemia cells, you will receive another treatment with decitabine by vein over 1 and 1/2 hours for 5 days.

Gemtuzumab may cause allergic reactions, nausea, and vomiting. To help decrease the risk of such side effects, you will receive Benadryl (diphenhydramine), acetaminophen, meperidine, and hydrocortisone. You may receive these drugs by vein, or by mouth on each of the days you get gemtuzumab ozogamicin.

Study Visits:

At every study visit, you will be asked if you have experienced side effects and to list any drugs you may be taking.

During Cycle 1, blood (about 2 teaspoons) will be drawn at least 1 time each week for routine tests. If the doctor thinks it is necessary, you may be asked to have additional blood drawn.

On Day 1 of every cycle, your performance status will be recorded and your vital signs will be measured.

On Days 1-5 of Cycle 1, your vital signs will be measured.

Between Days 12 and 16 of Cycle 1, you will have a bone marrow aspirate if you have a diagnosis of AML or high-risk MDS to check the status of the disease. This test may be delayed if your doctor does not think you are in remission.

During Cycles 2-3, blood (about 2 teaspoons) will be drawn for routine tests at least 2 times each month.

On Day 1 of Cycles 2 and beyond, you will have a physical exam, including measurement of your vital signs.

During Cycles 4 and beyond, blood (about 2 teaspoons) will be drawn for routine tests at least 1 time each month.

If the doctor thinks it is necessary, you will have a bone marrow aspirate every 1-3 months to check the status of the disease.

You should tell the study doctor about all drugs and supplements you are taking while you are on this study.

Length of Study:

You may receive the combination of decitabine and gemtuzumab ozogamicin for up to 6 cycles. After this, if your doctor thinks it is in your best interest, you may continue to receive decitabine alone for up to 24 cycles. During this part of study, your performance status will be recorded, you will have a physical exam, and your vital signs will be measured on Day 1 of each cycle. Blood (about 2 teaspoons) will be drawn for tests once a month. You will be taken off study early if the disease gets worse, you experience intolerable side effects, or your doctor thinks that it is no longer in your best interest to receive the study drug(s).

Long-Term Follow-up:

Once you are off study, you will have follow-up visits every month for up to 2 years. At these visits, blood (about 2 teaspoons) will be drawn for routine tests.

This is an investigational study. Gemtuzumab ozogamicin is FDA approved and commercially available for the treatment of AML that has come back after treatment in patients over the age of 65 years. Decitabine is FDA approved and commercially available for the treatment of MDS. The use of gemtuzumab ozogamicin and decitabine in combination is investigational.

Up to 100 participants will take part in this study. All will be enrolled at The University of Texas (UT) MD Anderson Cancer Center.

Recruitment information / eligibility

• Gender: Both
• Age group: 16 Years and older

Eligibility

Inclusion Criteria:

1. Understand and voluntarily sign an informed consent form.

2. Age >/= to 16 years at the time of signing the informed consent form.

3. Diagnosis of AML [other than acute promyelocytic leukemia (APL)] with refractory/relapsed disease. Patients with newly diagnosed AML will be eligible if not a candidate for intensive chemotherapy. Patients with high-risk (intermediate-2 or high by International Prognostic Scoring System (IPSS) or >/= 10% blasts) MDS will also be eligible. All non-hematological toxicity of previous cancer therapy should have resolved to </= grade 1 (except alopecia or other toxicities not involving major organs).

4. Eastern Cooperative Oncology Group (ECOG) performance status of </=3 at study entry.

5. Laboratory test results within these ranges (unless due to leukemia): Serum creatinine </= 2 mg/dL Total bilirubin </= 2 mg/dL aspartate aminotransferase (AST) (SGOT) and/or alanine aminotransferase (ALT) (SGPT) </= 2.5 * upper limit of normal (ULN) or </= 5 * ULN if related to disease

6. Women of childbearing potential (WCBP) must have a negative urine pregnancy test within 7 days and must either commit to continued abstinence from heterosexual intercourse or adopting at least one highly effective method of contraception. These methods include intra-uterine device, tubal ligation, partner's vasectomy, hormonal birth control pills. Men must agree not to father a child and agree to use a condom if his partner is of child bearing potential.

7. Active participants of the similar Protocol 2007-0882 (preceding study of decitabine and Mylotarg) are eligible to roll-over to this protocol without meeting the inclusion or exclusion criteria for this study.

8. For patients with MF only: Diagnosis of MF requiring therapy, including those previously treated by MF-directed therapy and relapsed or refractory; or if newly diagnosed then with intermediate or high risk according to Lille scoring system (adverse prognostic factors are: hemoglobin (Hb) < 10 g/dl, White blood cells (WBC) < 4 or > 30 * 10^9/L; risk group: 0 = low, 1 = intermediate, 2 = high), or with symptomatic splenomegaly (>/=10cm below left mid-costal margin).
