About this study

Official title: A Randomized, Active-Controlled, Double-Blind, Parallel Design, Multi-Center, Phase III Clinical Trial to Evaluate the Efficacy and Safety of GV1001 in Patients With Benign Prostatic Hyperplasia (BPH)

The current study is being conducted by the Sponsor to evaluate the efficacy and safety of GV1001 (0.56 mg and 1.12 mg) administered as a treatment for Benign prostate hyperplasia(BPH). The investigational drug, GV1001, was first developed as a cancer vaccine for use as active immunotherapy of cancer forms expressing telomerase (eg, pancreatic cancer, prostate cancer, etc.). Subsequently, it was found that GV1001 showed efficacy in alleviating BPH symptoms during in vivo studies by reducing the size of the prostate gland. Based on the result, the effectiveness of GV1001 as a treatment for BPH has been assessed in experimental animals that are designed to develop BPH.

It is considered that GV1001 acts to alleviate BPH and the results obtained from previous phase II study indicate that GV1001 may provide potential beneficial effects in BPH patients.

So this study is to verify the efficacy and safety of GV1001 on BPH population, large-scale clinical study than phase II.

Read the detailed description

This was a multi-center, randomized, Double-blind, Active-controlled, parallel design, Phase 3 study in patients with BPH. The study consisted of a Screening period, a 4-weeks Run-in/Washout period, a 24-week Treatment period, an Evaluation and Close-out Visit at Week 24.

There are a total of 3 groups in this study, which contained 2 study groups (GV1001) and 1 placebo group (0.9% normal saline). Approximately 417 patients are planned to be randomly assigned into the study in a 1:1:1 ratio. All patients are randomized into 1 of 3 treatment groups to ensure completion of patients.

The Screening period have a time period of 4 weeks before the beginning of Run-in/Washout period. Eligible patients entered into a 4-week Run-in/Washout period and receive placebo treatment, which will be completed before randomization on Week 0. All randomized patients will receive the investigational drug or a placebo via intradermal injection 12 times with a 2-week interval at Weeks 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 and 24. Efficacy evaluation will be conducted at Weeks 4, 8, 12, 16, 20 and 24, and safety evaluation will be conducted throughout the 24-weeks period.

What is being measured

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

  1. Change in International Prostate Symptom Score(IPSS)

    The amount of change from International Prostate Symptom Score(IPSS )compared to the baseline.

    The measures of the 7 items evaluating symptoms is evaluated from 0 to 5 for each item, the total coverage range is from 0 (no symptoms) to 35 (most severe symptoms).

    And the quality of life assessment is assessed from 0 (very satisfactory) to 6 (very unsatisfactory).

    Measured: Week 24

Secondary outcomes (10)
  1. Change in International Prostate Symptom Score(IPSS)

    The amount of change from Maximum(peak) Urinary Flow Rate compared to the baseline

    Measured: Weeks 12 and 24

  5. Change in Prostate-specific Antigen (PSA)

    The amount of change from Prostate-specific Antigen (PSA) compared to the baseline

    Measured: Weeks 12 and 24

  6. Change in Residual Urine Volume

    The amount of change from Residual Urine Volume compared to the baseline

    Measured: Weeks 12 and 24

Questions about this trial

What is this clinical trial studying?

A Phase 3 study of Benign Prostatic Hyperplasia (BPH), run by GemVax & Kael at 23 sites in South Korea.

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 17 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 25 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites in South Korea. 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?

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.

What does the primary outcome measure?

Change in International Prostate Symptom Score(IPSS) (time frame: Week 24). 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 25 Aug 2022.
