Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
- Patients must be = 1 and =25 years of age.

Diagnosis: Patients with relapse or refractory AML must have measurable disease ( >M1 marrow)

* 1st or greater relapse, OR
* Failed to go into remission after 1st or greater relapse, OR
* Failed to go into remission from original diagnosis after 2 or more induction attempts

Eligibility for patients with an M1 marrow; defined as >0.1% by flow or molecular testing (e.g. PCR).

* must include two serial marrows (at least 1-week apart) demonstrating stable or rising minimal residual disease (MRD) (i.e. not declining).
* Patients may have CNS or other sites of extramedullary disease. No cranial irradiation is allowed during the protocol therapy.
* Patients with secondary AML are eligible.
* Patients with Down syndrome are eligible.
* Patients with DNA fragility syndromes (such as Fanconi anemia, Bloom syndrome) are excluded.

Performance Level:

- Karnofsky >50% for patients >16 years of age and Lansky > 50% for patients = 16 years of age (See Appendix II for Performance Scales)

Prior therapy - Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.

1. Cytoreduction with hydroxyurea: hydroxyurea can be initiated and continued for up to 24 hours prior to the start of decitabine/vorinostat. It is recommended to use hydroxyurea in patients with significant leukocytosis (WBC >50,000/L) to control blast count before initiation of systemic protocol therapy.
2. Patients who relapsed while they are receiving cytotoxic therapy: at least 14 days must have elapsed since the completion of the cytotoxic therapy, except Intrathecal chemotherapy.

Hematopoietic stem cell transplant (HSCT):

- Patients who have experienced their relapse after a HSCT are eligible, provided they have no evidence of acute or chronic Graft-versus-Host Disease (GVHD) and are off all transplant immune suppression therapy for at least 7-days (e.g. steroids, cyclosporine, tacrolimus). Steroid therapy for non-GVHD and/or non-leukemia therapy is acceptable.

Hematopoietic growth factors:

- It must have been at least 7 days since the completion of therapy with GCSF or other growth factors at the time of enrollment. It must have been at least 14 days since the completion of therapy with pegfilgrastim (Neulasta ®)

Biologic (anti-neoplastic agent):

-At least 7 days after the last dose of a biologic agent. For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur. The duration of this interval must be discussed with the study chair.

Monoclonal antibodies: At least 3 half-lives of the antibody must have elapsed after the last dose of monoclonal antibody (i.e. Gemtuzumab = 36 days)

Immunotherapy: At least 42 days after the completion of any time of immunotherapy, e.g. tumor vaccines or CAR T-cell therapy.

XRT: Cranio or craniospinal XRT is prohibited during protocol therapy. No washout period is necessary for radiation given to non-CNS chloromas; >90 days must have elapsed if prior TBI, cranio or craniospinal XRT.

Prior Demethylating and/or HDAC Inhibitor Therapy: Patients who have received prior DNMTi (e.g. decitabine) and/or HDACi (e.g. vorinostat) therapy are eligible to participate in this Phase 1 study. At least 7 days must have passed from prior DNMTi or HDACi as a washout period.

Renal and hepatic function: Patients must have adequate renal and hepatic functions as indicated by the following laboratory values:

A. Adequate renal function defined as: Patient must have a calculated creatinine clearance or radioisotope GFR = 70ml/min/1.73m2 OR a normal serum creatinine based on age/gender.

B. Adequate Liver Function Defined as: Direct bilirubin < 1.5 x upper limit of normal (ULN) for age or normal, AND alanine transaminase (ALT) < 5 x ULN for age. The hepatic requirements are waived for patients with known or suspected liver involvement by leukemia. This must be reviewed by and approved by the study chair or vice chair.

Adequate Cardiac Function Defined as: Shortening fraction of = 27% by echocardiogram, OR ejection fraction of = 50% by radionuclide angiogram (MUGA).

Reproductive Function A. Female patients of childbearing potential must have a negative urine or serum pregnancy test confirmed within 1 week prior to enrollment.

B. Female patients with infants must agree not to breastfeed their infants while on this study.

C. Male and female patients of child-bearing potential must agree to use an effective method of contraception approved by the investigator during the study and for a minimum of 6 months after study treatment.
