Study of TCP-ATRA for Adult Patients With AML and MDS

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.

Exclusion criteria

• Therapy with moderate or strong CYP3A4 inhibitors or CYP3A4 inducers within 14 days prior to Cycle1 Day1.
• Therapy with Monoamine Oxidase Inhibitors (MAOIs), dibenzazepine derivatives, sympathomimetics, or Selective Serotonin Reuptake Inhibitors (SSRIs) within 14 days prior to Cycle1 Day1. (Patients actively receiving a safe substitute in the judgment of the Principal Investigator are eligible and may continue to receive the safe substitute during protocol treatment)
• Therapy with any investigational products, antineoplastic therapy, or radiotherapy within 14 days prior to Cycle1 Day1. Patients actively receiving hydroxyurea are eligible and may continue to receive hydroxyurea during protocol treatment.
• Candidates for standard and/or potentially curative treatments. (Candidate defined as a patient that is both eligible and willing)
• Major surgery within 28 days prior to Cycle1 Day1.
• Grade 2 or higher diarrhea as defined by NCI CTCAE Version 4.03 despite optimal antidiarrheal supportive care within 7 days prior to Cycle1, Day1.
• Myocardial infarction within 6 months (24 weeks) prior to Cycle1, Day1.
• Class III or IV heart failure as defined by the New York Heart Association (NYHA), uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. (Any ECG abnormality at screening has to be documented by the investigator as not medically relevant and confirmed by the Principal Investigator)
• Active and uncontrolled infection.
• 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.
• Known history of allergic reaction to TCP or ATRA.
• Symptomatic central nervous system (CNS) involvement.
• A concurrent second active and non-stable malignancy (Patients with a concurrent second active but stable malignancy are eligible).
• Patients with proliferative AML will be excluded defined by a white blood cell count (WBC) > 5 x ULN UNLESS, the white count has been suppressed to < 5 x ULN with hydroxurea and has remained below this level for at least 2 weeks prior to enrollment on study.
