Participant gender:
All
Summary
Primary Objective: 1. To evaluate side effects and maximum tolerated dose of azacitidine and valproic acid in patients with advanced cancer. Secondary Objectives: 1. To perform a preliminary assessment of the histone acetylation and DNA methylation effects of this combination on peripheral blood mononuclear cells (PBMC). 2. To assess the clinical anti-tumor activity (objective response including complete and partial responses) of this combination in patients with advanced cancer, in a descriptive fashion.

Criteria
Inclusion Criteria:

1. Patients with pathologically confirmed malignancy that is metastatic or unresectable
and refractory to standard therapy or for whom there is no standard therapy that
induces complete remission (CR) of at least 10% or an increased survival of at least 3
months.

2. There is no maximum allowable number of prior chemotherapy regimens, provided all
other eligibility criteria are met.

3. No chemotherapy, radiotherapy, investigational agents or surgery within four weeks.

4. ECOG performance status 2 or less.

5. Normal organ and marrow function - ANC > 1500/microL - Platelets > 100,000/microL -
Total bilirubin < 2.0 mg/dL - Creatinine < 2.0 mg/dL

6. The effect of azacytidine on the development of human fetus is unknown. Because of the
chemotherapy agents are known to be teratogenic, women and men of childbearing
potential must agree to use adequate contraception prior to study entry and for the
duration of the study.

7. Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

1. Uncontrolled concurrent illness such as neutropenic fever,shock, symptomatic
congestive heart failure (NYHA class III or IV).

2. Hypersensitivity to divalproex sodium, valproic acid, or valproate sodium

3. Known or suspected hypersensitivity to azacitidine or mannitol.

4. Nursing and pregnant women.

5. Patients with urea cycle disorders (UCD): - History of unexplained coma,
encephalopathy, or mental retardation - Encephalopathy associated with a protein load
- Pregnancy-related or postpartum encephalopathy - History of elevated plasma ammonia
or glutamine - Those with cyclical vomiting and lethargy, episodic extreme
irritability, ataxia, low BUN, or protein avoidance. - Those with a family history of
UCD or unexplained infant deaths (particularly males).

6. Patients with a known ornithine transcarbamylase disorder, history of unexplained coma
or a family history of ornithine transcarbamylase disorder are excluded from this
study.

7. Patients younger than 2-year old since valproic acid safety is not proven in this age
group.

8. Leukemias and MDS are excluded
