Eligibility
Part 1 Inclusion Criteria:

- Patient must have an Eastern Cooperative Oncology Group (ECOG) Performance Score of
0, 1, or 2

- Patient must have one of the following histologically or cytologically documented
measurable (may be measureable by tumor markers only, such as quantitative RT-PCR for
WT1 transcript for AML, or CA-125 for ovarian carcinoma) advanced stage malignancies:
non-small cell lung, ovarian, glioblastoma, and AML (not including acute
promyelocytic leukemia), known to overexpress the WT1 protein.

- Patient must qualify with a study specific HLA typing assay.

- Haematological parameters:

- Absolute neutrophil count (ANC) ? 1,000/?l

- Platelet count ? 10.0x10(to the 4th power)/?l (? 5.0 x 10(to 4th power)/?l after
stem cell transplant)

- Hemoglobin ? 9.0 g/dL

- Absolute lymphocyte count (ALC) ? 1,000/?l (? 500/?l after stem cell transplant)
Note: After completion of dose escalation, patients with AML are not required to
meet these hematologic criteria.

- Biochemical Parameters:

- serum creatinine of ? 1.5x upper limit of normal (ULN) for the reference lab.

the ULN for the reference lab

- Patient must have access to archival tumor tissue sample or agree to undergo biopsy
after study eligibility has been confirmed to obtain fresh sample for evaluation of
WT1 expression. In place of archival tumor tissue samples, subjects with AML should
have available a bone marrow aspirate and/or, bone marrow biopsy, with PCR for WT1
transcript performed before the first dose of study drug.

Note: The archived tumor tissue sample does not need to be delivered to the clinical site
prior to enrollment of the patient, however its availability should be confirmed through
provision of the accession number or other identification number.

schedules and must be able to follow verbal and written instructions.

- Patient must have an ECOG Performance Score of 0, 1, or 2 (refer to Appendix II).

- Patient has a life expectancy of at least 4 months.

- Patient must have histologically or cytologically documented measurable (may be
measurable by tumor markers only, such as quantitative RT-PCR for WT1 transcript for
AML) advanced stage glioblastoma or AML (not including acute promyelocytic leukemia),

criteria).

- Patient must have adequate renal function documented by a serum creatinine of ? 1.5
times the ULN for the reference lab.

mg/dl (? 3.0 mg/dl for patients with known Gilbert's syndrome) and ALT and AST ? 3
times the ULN for the reference lab.

- Patient must have access to archival tumor tissue sample or agree to undergo biopsy
after study eligibility has been confirmed to obtain fresh sample for evaluation of
WT1 expression. In place of archival tumor tissue samples, patients with AML should
have available a bone marrow aspirate and/or bone marrow biopsy with PCR for WT1
transcript performed before the first dose of study drug.

Note: The archived tumor tissue sample does not need to be delivered to the clinical site
prior to enrollment of the patient, however its availability should be confirmed through
provision of the accession number or other identification number.

• Patients with AML must be willing to undergo bone marrow aspiration/biopsy during
treatment if there are no other indicators of measureable disease.
