Clinical Trial Summary

This is a pilot study using decitabine and vorinostat before and during chemotherapy with vincristine, dexamethasone, mitoxantrone, and peg-asparaginase in pediatric patients with acute lymphoblastic leukemia (ALL).

Description:

Decitabine is a demethylating agent and vorinostat is a HDAC inhibitor. The use of demethylating agents and HDAC inhibitors in combination have been previously shown to have synergistic effects in altering neoplastic pathways of cancer cells and be well tolerated in human clinical studies. With the ability of decitabine and vorinostat to alter the abnormal cellular pathways of leukemic blasts and essentially turn off anti-apoptotic proteins, the leukemia cells have become primed for cytotoxic cell kill via chemotherapeutic agents. This study will ask the question as to whether or not the combination of decitabine and vorinostat followed by chemotherapy is feasible and whether it can positively impact outcome in patients with relapsed or refractory acute lymphoblastic leukemia.

Renal and Hepatic Function

• Patient's serum creatinine must be = 1.5 x institutional upper limit of normal (ULN) according to age. If the serum creatinine is greater than 1.5 times normal, the patient must have a calculated creatinine clearance or radioisotope GRF = 70mL/min/1.73m2.

• Patient's ALT and AST must be < 5 x institutional upper limit of norm ULN. The hepatic requirements are waived for patients with known or suspected liver involvement who would otherwise be eligible after consultation with the Study Chair or Vice Chair.

• Patient's total bilirubin must be = 1.5 x ULN. The hepatic requirements are waived for patients with known or suspected liver involvement who would otherwise be eligible.

Cardiac Function:

• Patient must have a shortening fraction = 27% by Echo or an ejection fraction = 50% by MUGA.

Reproductive Function

• Female patients of childbearing potential must have a negative urine or serum pregnancy test confirmed prior to enrollment.

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

• Male and female patients of child-bearing potential must agree to use an effective method of contraception approved by the investigator during the study.

Exclusion Criteria:

• Patients will be excluded if they are receiving Valproic Acid (VPA) therapy.

• Patients will be excluded if they have a known allergy to any of the drugs used in the study.

• Patients will be excluded if they have a systemic fungal, bacterial, viral or other infection that is exhibiting ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics or other treatment.

• Patients will be excluded if there is a plan to administer non-protocol chemotherapy, radiation therapy, or immunotherapy during the study period.

• Patients will be excluded if they have significant concurrent disease, illness, psychiatric disorder or social issue that would compromise patient safety or compliance with the protocol treatment or procedures, interfere with consent, study participation, follow up, or interpretation of study results.

• Patients will be excluded if they have had any positive fungal culture in the last 30 days prior to enrollment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Who Experienced a Dose Limiting Toxicity (DLT).	To evaluate the side effects of giving decitabine and vorinostat before and during chemotherapy using the standard drugs vincristine, dexamethasone, PEG-asparaginase and mitoxantrone.	6 weeks
Secondary	Disease Response Rate After Treatment.	Bone marrow evaluation was performed on Day 35 of study to evaluate treatment response. CR defined as attaining M1 marrow (<5% blasts) with no evidence of circulating blasts or extramedullary disease in addition to recovery of peripheral blood counts (ANC >750/uL and platelet count >75,000/uL). CRp was defined as attaining an M1 marrow with no evidence of circulating blasts or extramedullary disease in addition to recovery of ANC but insufficient recovery of platelets. CRi was attaining M1 marrow with no evidence of circulating blasts or extramedullary disease but insufficient recovery of ANC with or without sufficient recovery of platelets. PR was defined as no evidence of circulating blasts and achievement of M2 marrow (5-25% blasts) without new sites of disease and with recovery of ANC. SD is for patients who did not meet the criteria for PR, CR, CRp, or CRi. PD is an increase of at least 25% in the absolute number of leukemia cells or development of new sites.	6 weeks
