Sorafenib and 5-Azacitidine in Acute Leukemia + Myelodysplastic Syndrome

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical research study is to learn if 5-azacitidine and sorafenib can control the disease in patients with AML or MDS. The safety of this drug combination will also be studied.

Detailed Description
-----------------
The Study Drugs: Sorafenib is designed to block the function of important proteins in cancer cells. These proteins, when active, are partly responsible for the abnormal growth and behavior of cancer cells. 5-Azacytidine is designed to activate (turn on) certain genes in cancer cells whose job is to fight tumors. Study Drug Administration: If you are found to be eligible to take part in this study, you will receive 5-azacytidine either under the skin or by vein on Days 1-7 of each 28-day cycle. If by vein, the infusion will take about 10-40 minutes. You will take sorafenib by mouth 2 times a day about 12 hours apart, with water on empty stomach, every day. Each study cycle may last a little longer than 28 days, depending on how you are doing. Study Visits: Every week, blood (about 1 tablespoon) will be drawn for routine tests. Every week for the first 6 weeks, and then as often as your doctor thinks it is needed, you will have your blood pressure measured. Before each cycle: Your performance status will be recorded. You will have a physical exam, including measurement of your blood pressure and weight. Before every 2-4 cycles, you will have a bone marrow aspirate to check the status of the disease. Length of Study: 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 drugs if the disease gets worse or intolerable side effects occur. Your participation on the study will be over once you have completed the end-of-treatment and follow-up visits. End of Study Drug Administration Visit: After you have stopped taking the study drugs, the following tests and procedures will be performed: Your medical history will be recorded. Your performance status will be recorded. You will have a physical exam, including measurement of your blood pressure and weight. You will have a bone marrow aspirate collected to check the status of disease. This is an investigational study. Sorafenib is FDA approved and commercially available for kidney cancer and liver cancer. 5-Azacitidine is FDA approved for the treatment of MDS, but its combination with sorafenib is investigational. Up to 60 patients will take part in this study. All will be enrolled at MD Anderson.

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Patients with MDS, CMML or AML, who have failed pror therapy (including low and intermediate risk patient who have required prior therapy). Patients with MDS or CMML should have failed prior therapy with a hypomethylating agent and/or with lenalidomide. Patients who have received prior azacitidine are eligible if the treating physician feels that participation in the sudy is in the patients' best interest. Patients with AML should have failed any prior induction therapy or have relapsed after prior therapy. Patients with MDS or CMML who received therapy with hypomethylating agent and progress to AML are eligible at the time of diagnosis of AML regardless of any prior therapy for AML. Patients with any of the eligible diagnoses who have received no prior therapy are eligible if not candidates to receive or refuse standard therapy. Age of greater than or equal to 18 years of age. ECOG Performance Status less than or equal to 2. Adequate liver (bilirubin less than or equal 1.5 * upper limit of normal (ULN), ALT and AST less than or equal 2.5 * ULN and Alkaline phosphatase less than 4 * ULN if not related to leukemic disease) and renal (creatinine less than or equal 1.5* ULN) function. Amylase and Lipase must be less than or equal 2 * ULN. Patients must provide written informed consent. Patients must have been off chemotherapy for 2 weeks prior to entering this study, unless there is evidence of rapidly progressive disease, and must have recovered from the toxic effects of that therapy to at least grade 1. Use of hydroxyurea for patients with rapidly proliferative disease is allowed before the start of study therapy but should be stopped for 24 hours prior to initiation of azacitidine. Women of childbearing potential should be advised to avoid becoming pregnant with an adequate method of contraception (barrier or hormonal methods) and men should be advised to not father a child while receiving treatment with azacytidine. All men and women of childbearing potential must use acceptable methods of birth control throughout the study as described below: Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment. Men should use adequate birth control for at least 30 days after the last administration of sorafenib. Post-menopausal women (defined as no menses for at least a year) and surgically sterilized women are not required to undergo a pregnancy test. 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. Ability to understand and the willingness to sign a written informed consent. A signed informed consent must be obtained prior to any study specific procedures. INR less than 1.5. Patients receiving anti-coagulation treatment with an agent such as warfarin or heparin may be allowed to participate. For patients on warfarin, the INR should be measured prior to initiation of sorafenib and monitored at least weekly, or as defined by the local standard of care, until INR is stable. Exclusion Criteria: Nursing and pregnant females. Patients with acute promyelocytic leukemia are excluded unless multiply refractory and no other standard treatment strategies are available to them Patients with known allergy to sorafenib or azacitidine, mannitol or any of their components. Patients with known impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of sorafenib. Patients with any other known disease (except carcinoma in-situ) or concurrent severe and/or uncontrolled medical condition (e.g. uncontrolled diabetes, cardiovascular disease including congestive heart failure, myocardial infarction within 6 months and poorly controlled hypertension, chronic renal disease (creatinine clearance < 20 ml/min using the Cockcroft and Gault formula)., or active uncontrolled infection) which could compromise participation in the study. Patients with a known confirmed diagnosis of HIV infection or active viral hepatitis (B or C). Patients who have had any major surgical procedure within 28 days of Day 1. Patients unwilling or unable to comply with the protocol. Patients with known malignant disease of the central nervous system or advanced malignant hepatic tumors.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Phase I: Maximum Tolerated Dose (MTD) of Sorafenib Given With Azacitidine | MTD is defined as highest dose level in which 6 patients treated with at most 1 experiencing a dose limiting toxicity (DLT) during 1st cycle. One cycle of therapy is 7 days of azacitidine (AZA) and 28 days of sorafenib. Starting dose of Sorafenib is 200 mg twice a day azacitidine | 28 day cycle | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Phase II: Number of Participants With Response | Response according to International Working Group response criteria for Acute myeloid leukemia (AML) (JCO 2003; 21: 4642-9): CR defined by presence of <5% blasts in the bone marrow (BM), with >1 X 10^9/L neutrophils and >100 x 10^9/L platelets in the peripheral blood (PB) with no detectable extramedullary disease. Participants who met the above criteria but had neutrophil or platelet counts less than the stated values were considered to have achieved CRi (CR with incomplete recovery of PB counts) or CR with incomplete platelet recovery (CRp) if CR but platelets < 100 x 10^9/L but ≥ 50 x 10^9/L and platelet transfusion independent. Partial response (PR) required all of the hematologic values for a CR but with a decrease of >/= 50% in the percentage of blasts to 5% to 25% in the BM aspirate. | 90 days |
