About this study

Official title: A Phase 1 Dose Escalation Trial of Ipilimumab in Combination With CG1940 and CG8711 in Patients With Metastatic Hormone-Refractory Prostate Cancer

Ipilimumab, an antibody that blocks cytotoxic T-lymphocyte antigen 4, and GVAX have demonstrated anti-tumor activity in prostate cancer. Pre-clinical studies with this combination have demonstrated potent synergy. The purpose of this study is to investigate, using a phase-I 3+3 dose escalation design followed by an expansion cohort, the safety and efficacy of combined treatment with GVAX and ipilimumab in castration-resistant metastatic prostate cancer (CRPC) patients.

Read the detailed description

A promising immunotherapeutic approach in prostate cancer is whole-cell vaccination. Irradiated allogeneic tumor cells expressing GM-CSF generate a long-lasting and specific anti-tumor immunity in preclinical models. Results from several phase I and II trials showed Prostate GVAX (GVAX) to be well tolerated and suggested improved survival. Cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) is a crucial immune checkpoint molecule that down-regulates T-cell activation and proliferation. Ipilimumab, a fully human monoclonal antibody (IgG1) that blocks CTLA-4, promotes antitumor immunity, and has been demonstrated in two phase III trials to improve overall survival in metastatic melanoma patients. Pre-clinical studies of the anti-CTLA-4 antibody in combination with GM-CSF secreting tumor cell vaccines demonstrated a potent synergy. In this phase I study the investigators examine in CRPC patients whether ipilimumab can be safely combined with GVAX. In addition, the investigators will treat an additional 16 patients at a dose level of 3•0 mg/kg to determine the safety profile and antitumor effects of GVAX and ipilimumab in patients with CRPC.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • GVAX and ipilimumabDrug

    All patients receive a 500 million cell priming dose of granulocyte-macrophage colony-stimulating factor-transduced allogeneic prostate cancer cells (GVAX) intradermally on day 1 followed by bi-weekly intradermal injections of 300 million cells for a 24 week period. The vaccinations are combined with monthly intravenous administrations of ipilimumab. The dose-escalation part of this study will be performed using the standard 3+3 phase-I trial design. Patients will be enrolled in cohorts of three; each cohort will receive an escalating dose of ipilimumab at 0•3, 1•0, 3•0 or 5•0 mg/kg. Sixteen patients will be treated in an expansion cohort with GVAX and 3•0 mg/kg ipilimumab.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of patients with adverse events

    Measured: 7 months

Secondary outcomes (3)

  1. number of patients that have a tumor/PSA response

    Measured: 7 months

  2. number of patients that will develop a tumor-specific (e.g. PSMA, NY-ESO) antibody response as measured by ELISA

    Measured: 7 months

  3. the number of patients that have activated T cells and dendritic cells as measured by FACS

    Measured: 7 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GVAX and ipilimumab in people with Prostate Cancer, run by Amsterdam UMC, location VUmc at 1 site in Netherlands.

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 12 inclusion and 11 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: stopped early, as of the sponsor's last update on 16 Jan 2012. 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 Netherlands. 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 was stopped early (reason given: The study was terminated because Cell Genesys stopped all activities for GVAX.). Results are not available in the source record.

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.

What does the primary outcome measure?

Number of patients with adverse events (time frame: 7 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01510288, 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 16 Jan 2012.
