Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Men only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • 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 eligible:
Show all 24Show fewer
  • 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 disease.
  • 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 enrollment.
  • 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 progression.
  • 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

About this study

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

Dr. Frederick Millard, MD, Associate Clinical Professor at the UCSD Cancer Center, will be conducting a 12-week study in advanced prostate cancer patients. The study will be held at the UCSD Medical Center and will test an experimental investigational gene therapy vaccine designed to make the patient's immune system react against telomerase, an enzyme expressed in prostate cancer cells.

Read the detailed description

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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Transgenic Lymphocyte Immunization Vaccine (TLI) in people with Prostatic Neoplasms, run by Cosmo Bioscience at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 24 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Aug 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00061035, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Aug 2008.
