Trial Information

Pilot Study of Sodium Phenylbutyrate Plus Azacytidine


OBJECTIVES:

- Determine the ability of azacytidine in vivo to demethylate selected genes known to be
transcriptionally repressed in patients with acute myeloid leukemia, myelodysplasia,
non-Hodgkin's lymphoma, multiple myeloma, non-small cell lung cancer, or prostate
cancer.

- Determine the ability of phenylbutyrate plus azacytidine to induce transcription of
target genes that are known to be repressed as a consequence of DNA methylation in
these patients.

- Determine the effect of this treatment regimen upon gene methylation and histone
acetylation in target cells in these patients.

- Determine the technical feasibility of serially monitoring transcriptional activity and
methylation status of selected genes in vivo in these patients.

- Determine the safety and potential antitumor efficacy of this treatment regimen in
these patients.

OUTLINE: Patients receive azacytidine subcutaneously on days 1-7 and phenylbutyrate IV over
1-2 hours on days 8-12. Patients with acute myeloid leukemia who respond to therapy may
receive a second course approximately 10 days after the end of the first. Subsequent courses
in these patients, and all additional courses in all other patients, are repeated every 21
to 28 days in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study.

Inclusion Criteria


DISEASE CHARACTERISTICS:

- Diagnosis of one of the following neoplastic diseases:

- Acute myeloid leukemia

- Myelodysplasia

- Low or intermediate grade non-Hodgkin's lymphoma

- Multiple myeloma

- Non-small cell lung cancer

- Prostate cancer

- Failed prior conventional therapy and no other known curative therapy exists

- Patients with non-Hodgkin's lymphoma, non-small cell lung cancer, and prostate cancer
must have tumor cells in bone marrow or malignant effusions that are accessible for
bone marrow aspiration or paracentesis/thoracentesis NOTE: A new classification
scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of
"indolent" or "aggressive" lymphoma will replace the former terminology of "low",
"intermediate", or "high" grade lymphoma. However, this protocol uses the former
terminology.
