- Rate of Toxicity in Study Participants Receiving TCP/ATRA Combination Therapy [ Time Frame: 24 months ]The safety and tolerability of TCP/ATRA combination therapy in patients with Acute Myelogenous Leukemia (AML) and Myelodysplastic Syndromes (MDS). This will be measured by the rate of adverse events, serious adverse events and other toxicities in study participants receiving protocol therapy.
- Rate of Preliminary Efficacy of TCP/ATRA Combination Therapy [ Time Frame: 24 months ]Best response to TCP/ATRA combination therapy will be determined using serial blood and bone marrow sampling throughout the course of treatment. Responses will be documented according to revised/modified International Working Group (IWG) Response Criteria - Cheson et al. 2003 for AML and Cheson et al. 2006 for MDS. Morphologic complete remission (CR), cytogenetic CR, and molecular CR will be assessed by blood counts and simultaneous examination of the bone marrow fpr percentage of bone marrow blasts, as well as cytogenetics and molecular studies of bone marrow mononuclear cells
- Pharmacokinetics (PK) effects of TCP in plasma when combined with ATRA [ Time Frame: Baseline, Cycle 1, Cycle 2, 30 Days (+/-10 days) Post-End of Treatment ]Pharmacokinetics (PK) parameters will be determined using serial blood sampling at specified time points to determine PK effects of TCP in plasma when combined with ATRA. Non-compartmental methods of analysis will be used to determine TCP PK parameters following oral dosing of patients in Cycle 1. The following will be calculated: Observed maximum concentration (Cmax), the time at which Cmax occurred (Tmax), the area under the plasma concentration-time curve from time 0 to 24 hours post-dose (AUC24hr), the terminal disposition phase half-life (t1/2).
- Pharmacodynamic (PD) effects of TCP in peripheral blood and bone marrow when combined with ATRA. [ Time Frame: Baseline, Cycle 1, Cycle 2, 30 Days (+/-10 days) Post-End of Treatment ]Pharmacodynamics (PD) measurements will be obtained from serial blood and bone marrow sampling at specified time points to describe the PD effects of TCP when combined with ATRA. The following will be measured: Expression of CD11b by flow cytometry, gene expression analysis of leukemic blasts, measurement of Retinoic acid receptor alpha (RARα) and lysine (K)-specific demethylase 1A (LSD1) within leukemic blasts, leukemic engraftment of treated cells in immunodeficient mice.

Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
-
Confirmed diagnosis of one of the following:
- Relapsed/refractory Acute Myelogenous Leukemia (AML) as defined by the World Health Organization (WHO) criteria [therapy-related AML and/or secondary AML from an antecedent hematologic disorder not excluded].
- Relapsed/refractory Myelodysplasic Syndrome (MDS) as defined by the World Health Organization (WHO) criteria.
- Adult patients 18 years of age or older.
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2.
-
Adequate organ function as defined as:
- Total bilirubin ≤ 1.5 x upper limited of normal (ULN)
- ALT and AST must be ≤ 3 × ULN
- Creatinine ≤ 1.5 x ULN or calculated creatinine clearance > 50ml/min or
-
PT and aPTT ≤ 1.5 × ULN
- Patients with total bilirubin, Alanine transaminase (ALT), Aspartate transaminase (AST), Creatinine, prothrombin time (PT), and activated partial thromboplastin time (aPTT) levels outside the permitted range are eligible if, in the judgment of the Principal Investigator, the levels are related to the patient's AML or MDS.
- Suitable venous access to allow for all study related blood sampling (safety and research).
- Estimated life expectancy, in the judgment of the Investigator, which will permit receipt of at least 6 weeks of treatment.
- Able to understand and willing to signed the written informed consent and HIPAA document/s.

- Known human immunodeficiency virus (HIV) positive.
- Known hepatitis B surface antigen-positive.
- Known or suspected active hepatitis C infections (Patients who are hepatitis C surface antigen-positive are eligible).
- Female patients who are pregnant women or breast feeding. Confirmation that the patient is not pregnant will require a negative serum β-human chorionic gonadotropin (β-hCG) pregnancy test result obtained during screening; pregnancy testing is not required for post-menopausal or surgically sterilized women.
- Females of child bearing potential who refused to either practice 2 effective methods of contraception at the same time or abstain from heterosexual intercourse from the time of signing the informed consent through 30 days after the last dose of study drug.
- Males of child bearing potential who refuse to practice effective barrier contraception during the entire study treatment period and through 4 months after the last dose of study drug (includes males surgically sterilized - i.e. status post vasectomy).
- Serious medical or psychiatric illness/condition likely in the judgment of the Investigator to interfere with compliance to protocol treatment/research.
