Clinical Trial Summary

In this pilot study, eligible patients will be treated with 5 days of low dose daunorubicin for one cycle only. Any patient who receives treatment on this protocol will be evaluable for toxicity. Each patient will be assessed for the development of toxicity at all scheduled visits (Days 1-5). Following participation on this brief pharmacodynamic trial, patients can then proceed to other conventional or investigational therapies, as clinically indicated.

Description:

Disease relapse remains the primary challenge in the treatment of acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL). There is no standard of care treatment option for relapsed acute leukemia, and investigational therapies are recommended. Clinically targeting the leukemia stem cell (LSC) remains an unmet need in both AML and ALL. Therefore, a primary objective of this trial is to determine the molecular pharmacodynamic effects of low dose daunorubicin (DNR) on beta-catenin phosphorylation in serial bone marrow samples of patients with relapsed leukemia.

Prior to studying low-dose DNR in complex, multi-agent regimens, it is essential to confirm that it inhibits p-beta-catenin S552 in humans. This pilot study is designed to assess the feasibility and tolerability of low dose DNR administration to patients with relapsed/refractory AML and ALL, and obtain preliminary data regarding target engagement. A second objective is to demonstrate the safety and feasibility of low-dose daunorubicin administration in patients with relapsed/refractory acute leukemia.

Beta-catenin phosphorylation will be measured by immunohistochemistry assay in bone marrow samples taken from patients at study entry and at Day 8 following study therapy with low-dose DNR. The investigators will also measure the pharmacokinetics of low dose DNR in these patients, to enable preliminary PK-PD analyses and because there are essentially no PK data for DNR at comparable doses using modern analytical methodologies.

Following participation on this brief pharmacodynamic proof-of-concept trial, patients can then proceed to other conventional or investigational therapies, as clinically indicated.

Eligibility

Inclusion Criteria:

• Ability to understand and the willingness to sign a written informed consent or have parental consent.

• Age = 18 years

• Pathological confirmation by bone marrow documenting the following:

1. AML which has relapsed after Complete Remission

2. AML which has been refractory to two prior induction attempts

3. ALL which has relapsed after Complete Remission

4. ALL which has been refractory to two prior induction attempts

• Disease status allows delay of additional anti-leukemia therapy for the duration of the study (hydroxyurea is allowed for control of WBC throughout study)

• Able to adhere to the study visit schedule and other protocol requirements

• Cardiac ejection fraction =45% by ECHO

• Serum alanine aminotransferase or aspartate aminotransferase < 3 times the ULN

• Women of child-bearing potential and men with partners of child-bearing potential must agree to use adequate contraception prior to study entry, for the duration of study participation, and for 90 days following completion of therapy.

Exclusion Criteria:

• Concurrent use of conventional or investigational anticancer agents, except hydroxyurea (Standard prophylactic anti-infectives and medications to prevent/treat tumor lysis syndrome are allowed. Hydroxyurea may be used to keep the WBC<25,000. Additional anti-leukemia therapy is prohibited during the study.).

• Patient has received chemotherapy or radiotherapy within 2 weeks prior to entering the study or has not recovered from adverse events due to agents administered more than 2 weeks earlier, with the exception of hydroxyurea.

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to daunorubicin

• Patients with a total lifetime anthracycline exposure exceeding the equivalent of 900 mg/m2 of daunorubicin

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
