Official Title  ICMJE Phase I/II Pilot Trial of ATRA (Tretinoin) and TCP (Tranylcypromine) in Patients With Relapsed or Refractory Acute Myeloid Leukemia (AML) and no Intensive Treatment is Possible
Brief Summary

Longterm disease-free survival (DFS) of older patients with acute myeloid leukemia (AML) remains poor. The vast majority of AML patients relapses within two years after start of therapy1,2. In Acute Promyelocytic Leukemia (APL, AML M3), all-trans-retinoic-acid (ATRA; Tretinoin) induces differentiation and subsequently clinical remission. So far effective differentiation therapy does not exist in other AML subtypes. Recent preclinical data suggest that the combinatorial use of ATRA and tranylcypromine (TCP), an irreversible Monoamine-Oxidase (MAO) and Lysin-specific demethylase (LSD) inhibitor that also inhibits LSD1 (a histone H3 Lysine 4 demethylase), induces leukemia cell differentiation and leukemic stem cell exhaustion in vitro and in vivo in non-APL AML subtypes.

In this Phase I/II study the investigators will explore the feasibility, safety, as well as efficacy and of Tretinoin/TCP treatment in patients with relapsed or refractory AML or in patients with AML who are not eligible for intensive treatment. Patients will be treated with daily increasing doses of TCP (initially 10 mg/day, then +10 mg each day up to 80mg/d). After 7 days, ATRA will be added at a fixed dose (45 mg/sqm/day). Overall, 16 evaluable patients are going to be treated. The primary endpoint is the fraction of patients that achieve CR, CRp( complete response with incomplete recovery of platelets), CRi (complete response with incomplete recovery of granulocytes) and PR. Secondary endpoints are tolerability, safety as well as progression-free survival and overall survival. Serum levels of TCP will be regularly analyzed. Pharmacodynamic analyses will be performed with analyses of the inhibition of LSD1 by TCP. Further analyses will address the changes in Histone H3 lysine 4 tri demethylase (H3K4me3) levels in AML blasts and the differentiation status of AML blasts.

Taken together, this Phase I/II study will analyze feasibility, pharmacodynamics and effectivity of ATRA and TCP as differentiation therapy in AML.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Subjects must provide written informed consent prior to performance of study-specific procedures or assessments which are not routinely performed for diagnosis or monitoring of AML, and the subjects must be willing to comply with treatment and to follow up assessments and procedures
  2. Histologically or cytologically confirmed diagnosis of AML relapsed after or refractory to at least one induction regimen, or patients with AML at initial diagnosis who are not eligible for allogeneic transplant or intensive induction chemotherapy (investigator´s choice; for example reduced general state), except for AML M3 (acute promyelocytic leukemia).
  3. Age > 18 years
  4. Eastern Cooperative Oncology Group (ECOG) performance status of ≤3 (see Appendix, 3.2)
  5. Measurable disease burden (blasts in bonemarrow (BM) and/or peripheral blood (PB), extramedullary blasts [chloroma])
  6. Able to swallow and retain oral medication
  7. A life expectancy of at least 4 weeks
  8. Adequate contraception methods
  9. Adequate organ function

Exclusion Criteria:

  1. Patients with more than 20.000/µl leukocytes in the peripheral blood that cannot be controlled by Hydroxyurea.
  2. Patients with a valid option for intensive chemotherapy and/ or stem cell transplantation. (Patients after allogeneic stem cell transplant must be off immunosuppressive agents for at least 2 weeks prior to study entry and Graft- versus host disease must have resolved to Grade <= 2)
  3. Patients with less than 30% blasts in the bone marrow at the time of diagnosis. They should receive Azacytidine monotherapy.
  4. History of cancer that according to the Investigator might confound the assessment of the endpoints of the study
  5. Uncontrolled peptic ulcer disease or clinically significant gastrointestinal abnormalities which interfere with oral dosing or any unstable or serious concurrent condition (e.g., active uncontrolled infection)
  6. Poorly controlled hypertension (defined as systolic blood pressure (SBP) of ≥170 mmHg). Note: Initiation or adjustment of antihypertensive medication is permitted prior to study entry. BP must be re-assessed on two occasions that are separated by a minimum of 1 hour; on each of these occasions, the mean (of 3 readings) SBP/ DBP(diastolic blood pressure) values from each BP assessment must be <140/90 mmHg in order for a subject to be eligible for he study.
  7. Prolongation of corrected QT interval (QTc) > 480 ms
  8.

  10. History of cerebrovascular infarction or bleeding, pulmonary embolism (PE), or untreated deep venous thrombosis (DVT) within the past 6 months. Note: Subjects with recent DVT who have been treated with therapeutic anti- coagulant agents for at least 6 weeks are eligible
  11. Evidence of serious active bleeding or bleeding diathesis (except for bleeding or petechiae due to AML- related thrombocytopenia which will be treated using platelet transfusions). Also, patients with known endobronchial lesions and/ or lesions infiltrating major pulmonary vessels will be excluded from the study due to excess risk of bleeding.
