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

  • 1. Age is ≥ 18 years
  • 2. Written informed consent provided prior to the initiation of study procedures
  • 3. Histologically proven adenocarcinoma of the prostate initially diagnosed ≤12 months of Screening. All biopsy slides with participant information redacted must be submitted for blinded independent central review (BICR).
  • 4. Prostate cancer diagnosis determined by BICR as one of the following: 4a. ISUP Grade Group 1 with 3 or more cores positive from a systematic (≥10 cores) biopsy 4b. ISUP Grade Group 1 with ≥ 1 core positive with ≥50% cancer involvement from a systematic (≥10 cores) biopsy 4c. ISUP Grade Group 1 from 3 or more positive cores from any combination of cores from a systematic (≥10 cores) biopsy and MRI targeted biopsy (note: multiple cores from each MRI targeted lesion will count as 1 core) 4d. ISUP Grade Group 1 from a negative systematic (≥10 cores) biopsy and an MRI targeted core positive with ≥50% cancer involvement 4e. ISUP Grade Group 2 from a systematic (≥10 cores) biopsy with <50% of the total number of any cores positive for cancer 4f. ISUP Grade Group 2 from a negative systematic (≥10 cores) biopsy and MRI targeted core(s) positive for Gleason 3+4 (see note below) 4g. ISUP Grade Group 2 from any combination of cores from a systematic (≥10 cores) biopsy and MRI targeted biopsy (see note below)
  • Note for 4f and 4g: the total number of positive cores must be <50% of total cores from both the systematic biopsy and MRI targeted lesions; each MRI targeted lesion, irrespective of multiple positive cores, will each count as 1 core for the total number of positive cores, e.g., 4 targeted lesions with 2 positive cores each will only add 4 to the total core count.
  • 5. Participant consents to standard of care for biopsy frequency of 2 on-study prostate biopsies and to provide biopsy tissue for study endpoint analysis.

About this study

Official title: A Randomized Phase 3, Open-Label Trial of Sipuleucel-T Administered To Patients On Active Surveillance For Newly Diagnosed Prostate Cancer

The ProVent study is a randomized, open-label study designed to assess the efficacy of sipuleucel-T in reducing the progression of lower risk non-metastatic prostate cancer compared to participants followed on active surveillance as standard of care.

Read the detailed description

The ProVent Study is designed to look at participants who receive sipuleucel-T compared to control participants followed on active surveillance (AS). The study will enroll participants being followed by AS and initially diagnosed within 12 months prior to Screening with either International Society of Urological Pathology (ISUP) Grade Group 1 or 2 adenocarcinoma of the prostate.

The Screening Phase will begin at the completion of the informed consent process and continues until randomization. After Screening assessments are completed, eligible participants will be randomized 2:1 to the sipuleucel-T arm or the control arm. Participants randomized to sipuleucel-T arm will receive product as described in the sipuleucel-T approved label.

Participants will undergo their first leukapheresis within 60 days of randomization.

Participants randomized to the control arm will be followed on AS. The Active Phase will begin at randomization and continues through completion of the end of Active Phase study visit (within 30 days of Biopsy 2). Once a Participant from either the sipuleucel-T or control arms completes the end of Active Phase visit, they will enter the Follow-up Phase and complete Follow-up Phase visits every 6 months starting from their last Active Phase visit. The Follow-up Phase visits end when the last Participant enrolled completes Biopsy 2 and end of Active Phase visit or until the study is terminated by the sponsor.

What participants receive

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

  • sipuleucel-TBiological

    Sipuleucel-T is an autologous cell product consisting of antigen presenting cells (APCs) loaded with recombinant fusion protein composed PAP linked to GM-CSF (PA2024), a recombinant fusion protein composed of prostatic acid phosphatase (PAP), linked to granulocyte-macrophage colony-stimulating factor (GM-CSF).

Study groupRoleWhat they receive
Treatment Group: Sipuleucel-TExperimentalSipuleucel-T is an autologous cellular immunotherapy available as a suspension for intravenous infusion. Participants randomized to sipuleucel-T arm will receive 3 infusions of sipuleucel-T at approximately 2-week intervals.
Receives: Biological: sipuleucel-T
Control Arm: Active SurveillanceNo interventionParticipants randomized to the control arm will be followed on Active Surveillance described in the schedule of events.

What is being measured

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

  1. Efficacy of Sipuleucel-T Measured as the Percentage of Subjects Without Histological Reclassification (Gleason Group Upgrade).

    Percentage of participants without histological reclassification (Gleason group upgrade) within 36 months of randomization as determined by Blinded Independent Central Review (BICR)

    • Upgrade is defined as participants at randomization with either International Society of Urological Pathology (ISUP) Grade Group 1 (Gleason 3+3) upgraded to Grade Group 2 (Gleason 3+4) or higher or participants at randomization with Grade Group 2 upgraded to Grade Group 3 (Gleason 4+3) or higher.

    Measured: Once all participants have completed at least 3 years following randomization

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing sipuleucel-T in people with Adenocarcinoma of the Prostate, run by Dendreon at 56 sites 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 10 inclusion and 16 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 8 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 56 sites 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Efficacy of Sipuleucel-T Measured as the Percentage of Subjects Without Histological Reclassification (Gleason Group Upgrade). (time frame: Once all participants have completed at least 3 years following randomization). 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 8 Oct 2024.
