PHASE I/II STUDY OF SORAFENIB AND 5-AZACITIDINE FOR THE TREATMENT OF PATIENTS WITH REFRACTORY OR RELAPSED ACUTE LEUKEMIA AND MYELODYSPLASTIC SYNDROME (MDS) - (VZ-MDS-PI-0227)
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.
Disease Group: Leukemia
Treatment Agent: 5-Azacytidine,Sorafenib
Treatment Location: Only at MDACC
Objectives Primary objectives: 1. To determine the clinical activity of the combination of AZA and sorafenib in patients with refractory or relapsed acute leukemias and MDS. 2. To determine the toxicity profile of the combination of AZA and sorafenib in patients with refractory or relapsed acute leukemias and MDS. Secondary objectives: 1. To determine induction of hypomethylation, DNA damage and FLT3 signaling during therapy with this combination and its correlation with response.
IRB Review and Approval Date: 01/11/2011
Recruitment Status: Not Accepting
Projected Accrual: N/A
1) Patients with MDS, CMML or AML, who have failed pror therapy
(including low and intermediate risk patienst who have required prior therapy).
2) 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.
3) Patients with AML should have failed any prior induction therapy or have relapsed after prior therapy.
4) Patients with MDS or CMML who received therapy with hypomethylating agent and progress to AML are elgible at the time of diagnosis of AML regardless of any prior therapy for AML.
5) Patients with any of the eligible diagnoses who have received no prior therapy are eligible if not candidates to receive or refuse standard therapy.
6) Age of greater than or equal to 18 years of age.
7) ECOG Performance Status less than or equal to 2.
8) Adequate liver (bilirubin less than or equal 1.5 x ULN, ALT and AST less than or equal 2.5 x ULN and Alkaline phosphatase less than 4 x ULN if not related to leukemic disease) and renal (creatinine less than or equal 1.5x ULN) function. Amylase and Lipase must be less than or equal 2 X ULN.
9) Patients must provide written informed consent.
10) 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.
11) 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 adminstration 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.
12) 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.
13) 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.
14) 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.
15) 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.
1) Nursing and pregnant females.
2) Patients with acute promyelocytic leukemia are excluded unless multiply refractory and no other standard treatment strategies are available to them
3) Patients with known allergy to sorafenib or azacitidine, mannitol or any of their components.
4) Patients with known impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of sorafenib.
5) 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 Cockroft and Gault formula)., or active uncontrolled infection) which could compromise participation in the study.
6) Patients with a known confirmed diagnosis of HIV infection or active viral hepatitis (B or C).
7) Patients who have had any major surgical procedure within 28 days of Day 1.
8) Patients unwilling or unable to comply with the protocol.
9) Patients with known malignant disease of the central nervous system or advanced malignant hepatic tumors.
10) Cardiac disease: Congestive heart failure greater than class II NYHA. Patients must not have unstable angina (anginal symptoms at rest) or new onset angina (began within the last 3 months) or myocardial infarction within the past 6 months.
11) Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy.
12) Uncontrolled hypertension defined as systolic blood pressure greater than 140 mmHg or diastolic pressure greater than 90 mmHg, despite optimal medical management.
13) Active clinically serious infection greater than CTCAE v4. Grade 2 not controlled with antibiotics.
14) Thrombolic or embolic events such as a cerebrovascular accident including transient ischemic attacks within the past 6 months.
15) Pulmonary hemorrhage/bleeding event greater than CTCAE v4. Grade 2 within 4 weeks of first dose of study drug.
16) Any other hemorrhage/bleeding event greater than CTCAE v4. Grade 3 within 4 weeks of first dose of study drug.
