About this study

Official title: An Open-Label, Single Arm, Multicenter Study to Evaluate the Efficacy and Safety of Intravesical VB4-845 Injection in Patients With Non-Muscle Invasive Bladder Cancer

Because of the high risk for development of muscle invasive disease, cystectomy is recommended for CIS, high-grade Ta and T1 patients who experience disease recurrence following intravesical therapy. VB4-845 injection is an experimental agent that may provide an alternative to cystectomy

Read the detailed description

Bladder cancer is the 6th most common cancer in the United States, affecting more men than women. The usual first treatment for NMIBC (Ta, T1,and CIS) is transurethral resection of the bladder tumors followed by intravesical immunotherapy, most commonly with bacillus Calmette-Guérin (BCG).

Because of the high risk for development of muscle invasive disease, cystectomy is recommended for CIS and high-grade Ta and T1 patients who experience disease recurrence following intravesical therapy. For patients unable or unwilling to undergo cystectomy, treatment options are limited.

VB4-845 injection is a recombinant fusion protein produced in Escherichia coli (E. coli) that expresses a humanized single-chain antibody fragment specific for the epithelial cell adhesion molecule (EpCAM) antigen linked to exotoxin A (ETA[252-608]). Once bound to the EpCAM antigen on the surface of carcinoma cells, Vicinium is internalized through an endocytic pathway. The ETA(252-608) is cleaved off and induces cell death by irreversibly blocking protein synthesis.

This is an open-label, non-randomized, multicenter bridging study in Chinese patients with NMIBC, specifically CIS (with or without papillary disease), high-grade Ta or any grade T1 papillary disease, who have previously failed BCG treatment (i.e., not those who are intolerant) with or without interferon. The study consists of a Screening period, a 12-week Induction Phase, and a Maintenance Phase of up to 21 monthly cycles for a total treatment period of up to104 weeks.

What is being measured

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

  1. Complete response rate

    Complete response rate in patients with CIS with or without resected papillary disease following initiation of VB4-845 injection therapy

    Measured: up to 6 months

Secondary outcomes (4)
  1. Recurrence-free rate

    Recurrence-free (RF) rate in patients with high-grade Ta or any grade T1 papillary disease (without CIS)

    Measured: up to 6 months

  2. Complete response rate

    Complete response rate in patients with CIS with or without resected papillary disease following initiation of VB4-845 injection therapy

    Measured: up to 3 months

  3. Recurrence-free rate

    Recurrence-free (RF) rate in patients with high-grade Ta or any grade T1 papillary disease (without CIS)

    Measured: up to 3 months

  4. Number of participants with treatment-related adverse events as assessed by CTCAE v5.0

    Frequency and severity of adverse events. Including adverse events (AEs), change in physical examination findings, change in vital signs, clinical laboratory testing for systemic safety,including liver function, renal function, compelete blood count, and clinical chemistries.

    Measured: Every 4 weeks up to 104 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing VB4-845 Injection in people with Non-Muscle Invasive Bladder Cancer, run by Qilu Pharmaceutical Co., Ltd. at 1 site in China.

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 8 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 26 Apr 2021. 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 China. 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?

Results are not available in the source record.

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

Contact Oliver Kong, CMO (0531-83129659, oliver.kong@qilu-pharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Complete response rate (time frame: up to 6 months). 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 26 Apr 2021.
