Trial Information

A Phase 1, Evaluation of Transgenic Lymphocyte Immunization Vaccine in Subjects With Prostate Adenocarcinoma

The goal of the study is to determine the safety, feasibility, and tolerability of
transgenic lymphocyte immunization (TLI). In this process patient's lymphocytes are
rendered transgenic for a gene coding for selected portion of telomerase an enzyme expressed
in the vast majority of cancer cells. Transgenic cells are then returned to the patient to
produce an immune response targeted at cancer cells expressing telomerase. The Phase 1
trial will evaluate TLI in patients with advanced, androgen-independent prostate cancer with
metastases confined to lymph nodes or bones.

Inclusion Criteria:

- 18 years of age or older, able to understand and sign the informed consent form.

- HLA-A2 positive.

- Expected survival ≥ 6 months.

- Histological evidence of adenocarcinoma of the prostate.

- (ECOG) Performance status 0, 1 or 2.

The following categories of subjects with androgen-independent prostate cancer are

- Progression of bidimensionally measurable disease assessed within 84 days (12 weeks)
prior to enrollment.

- Progression of evaluable but not measurable disease (i.e., bone scan) assessed within
112 days (16 weeks) prior to enrollment.

- Rising PSA- Rising PSA is defined as at least two consecutive rises in PSA to be
documented over a reference value (measure 1). The first rising PSA (measure 2) must
be taken at least 7 days after the reference value. A third confirmatory PSA measure
is required (2nd beyond the reference level) to be greater than the second measure,
and it must be obtained at least 7 days after the 2nd measure. If this is not the
case, a fourth PSA is required to be taken and be greater than the second measure.
The subject must have a PSA ≥ 5 ng/ml in addition to increasing PSA to be eligible.
No minimum PSA is required for subjects with measurable disease or non-PSA evaluable

- All subjects must have had a CT scan of the abdomen and pelvis within 84 days (12
weeks) prior to enrollment.

- All subjects must also have had a bone scan within 112 days (16 weeks) prior to

- Subjects must have been surgically or medically castrated. If method of castration
is LHRH agonists (leuprolide or goserelin), then the subject should be willing to
continue the use of LHRH agonists. Castration using LHRH agonist should not be
interrupted and subjects who have stopped treatment should be willing to restart.

- If the subject has been treated with non-steroidal anti-androgens (flutamide,
bicalutamide, nilutamide or ketoconazole), they must have been stopped at least 28
days prior to enrollment for flutamide or ketoconazole and at least 42 days prior to
enrollment for bicalutamide or nilutamide and the subjects must have demonstrated

- Subjects may have received prior surgery. However, at least 21 days must have elapsed
since completion of surgery and subject must have recovered from all side effects.

- All subjects must have pre-study PSA within 28 days of enrollment.

Subjects must meet the following initial laboratory criteria:

- granulocytes ≥ 1500/ul

- platelet count ≥ 100,000/ul

- hemoglobin ≥ 10 gms/dl

- bilirubin ≤ 1.5 x ULN

- AST ≤ 1.5 x ULN

- Creatinine ≤ 1.5 x ULN

- Testosterone < 50ng/ml for those who have not had bilateral orchiectomy

- PSA ≥ 5ng/ml if no measurable disease
