About this study

Official title: A Phase I Neoadjuvant Study of In-situ REIC/Dkk-3 Therapy Followed By Prostatectomy in Patients With High Risk Localized Prostate Cancer

This is a phase I neoadjuvant gene therapy followed by prostatectomy, open-label, dose-escalation trial for prostate cancer patients with high risk of local recurrence after radical prostatectomy. Patients entered into this trial will have Prostate Cancer of Clinical stage T1c, T2 or T3 with a Gleason Score of between 7 (4+3) and 10 at the time of enrollment. Patients will receive three 1 mL injections (3 mL total volume) of Ad-REIC/Dkk-3 into the prostate prior to undergoing a radical prostatectomy. Three patients will be treated at each dose level unless a dose-limiting toxicity (DLT) is observed or MFD (defined as 1 x 10e12 vp/treatment) is achieved with expansion for up to 6 more patients at the MTD or MFD.

Read the detailed description

This is a phase I neoadjuvant gene therapy followed by prostatectomy, open-label, dose-escalation trial for prostate cancer patients with high risk of local recurrence after radical prostatectomy. Patients entered into this trial will have Prostate Cancer of Clinical stage T1c, T2 or T3 with a Gleason Score of between 7 (4+3) and 10 at the time of enrollment.

Patients will receive three 1 mL injections (3 mL total volume) of Ad-REIC/Dkk-3 into the prostate under transrectal ultrasound-guidance (TRUS) and, patients will undergo a radical prostatectomy four weeks after the injection.

Patients will receive treatment at one of three dose levels in a sequential dose-escalating design.

Three patients will be treated at each dose level unless a dose-limiting toxicity (DLT) is observed or MFD (defined as 1 x 10e12 vp/treatment) is achieved. Enrollment will proceed to the next dose level if 0 of 3 patients experiences a DLT; if one of the first 3 patients experiences a DLT, three additional patients will be enrolled until a second patient experiences a DLT (which defines the toxic dose) or until six total patients have been treated at that dose level, whichever comes first. If a second DLT is not experienced within that cohort, dose escalation may continue.

Additional patients will be enrolled a minimum of 14 days after treatment of the first patient in the cohort (sentinel patient).

If 2 DLTs are observed within a cohort, enrollment into the cohort will cease and the dose level immediately preceding that dose will be determined to be the MTD. If 2 non-lethal DLTs are observed in Cohort 1, a lower dose cohort (Cohort -1) may be initiated.

Once the MTD is defined, an additional 3-6 patients may be enrolled at that dose level to further evaluate safety of the MTD.

Patients will undergo a scheduled radical prostatectomy approximately 4 weeks after the Ad-REIC/Dkk-3 injection. The prostate tissue removed will be retained and for those patients treated at the MTD, assessed for REIC expression and evidence of apoptosis by TUNEL staining.

What participants receive

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

  • Ad-REIC/Dkk-3Biological

    REIC (Reduced Expression in Immortalized Cells) protein is down regulated in a variety of cancer cell lines including prostate tumors. The REIC gene is identical to the Dickkopf-3 (Dkk-3) gene that is a member of the Dickkopf gene family. Ad-REIC/Dkk-3 is designed as a viral vector that delivers a DNA plasmid capable of producing intracellular REIC protein. The expression plasmid includes the full-length human cDNA sequence for REIC. The adenovirus vector is a transport mechanism to infuse the REIC/Dkk-3 plasmid into the cell providing a temporary transfusion of REIC protein.

What is being measured

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

  1. Maximum Tolerated Dose

    To define the Maximum Tolerated Dose (MTD) for intertumoral injection (IT) of Ad-REIC/Dkk-3 viral vector.

    Measured: 7-days

  2. Safety evaluation of adverse drug experiences compared with historical precedence

    To assess the safety of in-situ therapy with REIC/Dkk-3 gene in prostate cancer patients with high risk of local recurrence after radical prostatectomy. Safety events will be evaluated and assessed with regards to causality and in comparison with historical precedence for this patient population.

    Measured: 28-days

Secondary outcomes (1)
  1. Pharmacodynamic Efficacy Markers

    To assess the effectiveness of Ad-REIC/Dkk-3 in the treatment of prostate cancer as evaluated by the PSA biomarker and histologic examination of extracted prostate tissue.

    Measured: 28-days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ad-REIC/Dkk-3 in people with Prostate Cancer, run by Momotaro-Gene Inc. 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 11 inclusion and 7 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: withdrawn, as of the sponsor's last update on 23 Aug 2013. 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 was withdrawn before enrolling participants, so there are no results.

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?

Maximum Tolerated Dose (time frame: 7-days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Aug 2013.
