FTS Study in Patients With Advanced Hematologic Malignancies

Inclusion Criteria:

1. Patients must have relapsed/refractory hematologic malignancies for which no standard therapies are anticipated to result in a durable response or who have failed potentially curative therapy, or who refuse or are considered unsuitable for standard therapy. Patients with poor-risk myelodysplastic syndromes (MDS) \[IPSS ≥ 1.5\], chronic myelomonocytic leukemia (CMML), relapsed/refractory leukemias including
2. CONTINUATION OF # 1: acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), or chronic myelogenous leukemia (CML) in blastic phase, or with agnogenic myeloid metaplasia (AMM) are eligible.
3. Patients are eligible if they are 18 years or older
4. In the absence of rapidly progressing disease, the interval from prior treatment to time of study drug administration should be at least 2 weeks for cytotoxic agents, or at least 5 half-lives for noncytotoxic agents. If the patient is on hydroxyurea to control peripheral blood leukemic cell counts, the patient must be off hydroxyurea for at least 24 hours before initiation of treatment on this protocol. Persistent chronic clinically significant toxicities from prior chemotherapy must not be greater than Grade 1
5. Patients with active CNS disease are included and will be treated concurrently with intrathecal therapy
6. Patients must have ECOG performance status (PS) of 0 - 2
7. Have serum creatinine less than or equal to 2.0 mg/dl; total bilirubin less than or equal to 2.0 mg/dl; ALT and/or AST no more than 3X the upper limit of normal range unless abnormal parameter level is considered related to leukemia.
8. Patients must be willing and able to sign written informed consent and be able to comply with the study protocol for the duration of the study
9. Females of childbearing potential and males are required to practice adequate contraception or abstinence prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

Exclusion Criteria:

1. Impaired cardiac function, including any one of the following: myocardial infarction within the previous 3 months; symptomatic coronary insufficiency or heart block; uncontrolled congestive heart failure; moderate or severe pulmonary dysfunction
2. Have an active uncontrolled infectious process
3. Significant impairment of gastrointestinal (GI) function of GI disease that may significantly alter the absorption of FTS(e.g. ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection)
4. Have received prior radiotherapy administered to more than 30% of marrow-bearing bone mass
5. Women patients are pregnant or lactating
6. Patients who have had major surgery without full recovery or major surgery within three weeks of FTS treatment start
7. Patients with marked baseline prolongation of QT/QTc interval (QTc interval greater than 480) using the Fridericia method as a main method of QTC analysis
8. Patients unwilling or unable to comply with the protocol
