Mesothelioma Clinical Trial

Purpose

RATIONALE: Vaccines made from peptides may help the body build an effective immune response to kill cancer cells. Biological therapies, such as GM-CSF, may stimulate the immune system in different ways and stop cancer cells from growing. Giving vaccine therapy together with GM-CSF may kill more cancer cells.

PURPOSE: This phase I trial is studying vaccine therapy together with GM-CSF to see how well it works in treating patients with acute myeloid leukemia, myelodysplastic syndromes, non-small cell lung cancer, or mesothelioma.

Official Title: Pilot Trial of a WT-1 Analog Peptide Vaccine in Patients With Thoracic and Myeloid Neoplasms

Further study details as provided by National Cancer Institute (NCI):

Primary Outcomes: Safety and immunogenicity; Immune response as measured by T-cell proliferative response, delayed-type hypersensitivity against WT-1 peptides, or ELISPOT
Secondary Outcomes: Antileukemic effects; Clinical and molecular response; Antitumor response by CT scan based on RECIST criteria; Toxicity as measured by NCI CTC v. 3.0
Expected Total Enrollment:  20

Study start: October 2006

OBJECTIVES:

Primary

• Determine the safety and immunogenicity of the WT-1 vax peptide vaccine in patients with acute myeloid leukemia, myelodysplastic syndromes, non-small cell lung cancer, or mesothelioma.

Secondary

• Determine the antitumor effects of this vaccine in these patients.

OUTLINE: This is a pilot study. Patients are stratified according to disease type (acute myeloid leukemia [AML] and myelodysplastic syndromes [MDS] vs non-small cell lung cancer and mesothelioma).

Patients receive vaccine comprising WT-1 vax peptide emulsified in Montanide ISA-51 subcutaneously (SC) once a week during weeks 0, 4, 6, 8, 10, and 12 and sargramostim (GM-CSF) SC twice a week, during weeks 0, 4, 6, 8, 10, and 12, on the day of and 2 days prior to each vaccination. Patients who have an immunologic response and have not had disease progression may continue with up to 6 more vaccinations administered approximately every month.

Blood samples are acquired at baseline, week 8, and week 14. Samples are examined by polymerase chain reaction (PCR) to measure levels of WT-1 and by T-cell proliferative response, delayed-type hypersensitivity against WT-1 peptides, or ELISPOT to measure immune response.

Bone marrow samples are acquired from patients with AML and MDS at baseline and week 14. Samples are examined by PCR to measure levels of WT-1 and by multiparameter flow cytometry to measure residual disease.

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