About this study

Official title: Intravesical Administration of Durvalumab (MEDI4736) to Patients With High-risk, Non-muscle-invasive Bladder Cancer (NMIBC). A Phase II Study With Correlative

Research Hypothesis Approximately 75% of patients with bladder cancer (BC) present with a disease confined to the mucosa (stage Ta, CIS) or submucosa (stage T1) (non-muscle invasive BC [NMIBC]). For high grade NMIBC, i.e. TaG3, T1G3 and CIS, intravesical bacillus Calmette-Guérin (BCG) immunotherapy is the treatment of choice, given that it prevents recurrence and reduces the odds of progression to MIBC. However, since initial BCG therapy fails in approximately 40% of patients over a 2-year period, new treatment options for these patients are of utmost importance.

In that field of research durvalumab, a human monoclonal antibody that binds programmed cell death ligand-1 (PD-L1), demonstrated meaningful clinical activity as well as manageable safety profile in PD-L1-positive patients with BC, many of whom were heavily pretreated. Certain studies using systemic administration of anti-PD1 agents for BCG refractory NMIBC are ongoing. Nevertheless, intravesical administration may be advantageous, since selective bladder tumor uptake of monoclonal antibodies following intravesical administration, while this method results in negligible absorption in the circulation and, therefore, minimal risk of systemic toxicity. This notion is supported by the findings of a recent study of intravesical administration of recombinant adenovirus-mediated interferon-α2b gene therapy (rAd-IFNα), No rAd-IFNα DNA was detected in the blood. Furthermore, no systemic toxicity was reported in a phase II study using the same agent.

The investigators, therefore, propose a phase II study of intravesical administration of durvalumab in patients with BCG refractory NMIBC. Since no safety or efficacy data specifically on intravesical administration of durvalumab exist, a run-in part will precede the main phase II, in order to confirm safety of the procedure and to reject a futility hypothesis, as described in the following sections of the protocol. Correlative studies of potential biomarkers in tumor tissue before and after durvalumab instillation are also proposed.

Receives: Biological: Durvalumab

What is being measured

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

  1. The maximum tolerated dose (MTD) of Durvalumab among 500mg, 750mg and 1000mg that will be given intravesically to patients with BCG-refractory NMIBC

    Measured: 6 months after trial initiation

  2. The possibility of a rate of high-grade relapse free (HGFR) that it is defined as the development of TaG3, T1G3, CIS or muscle-invasive disease after the initiation of durvalumab therapy.

    Measured: 6 months after trial initiation

  3. Efficacy of intravesical administration of Durvalumab at MTD in patients with BCG-refractory NMIBC assessed by 1-year high-grade-relapse-free (HGRF)-rate

    Measured: 1 year after patient enrollment

Secondary outcomes (4)
  1. Toxicity of the MTD of intravesical Durvalumab administration assessed according to the NCI CTC version 4.03 except from local irritation.

    Local irritation will be assessed according to the following criteria: Grade 1: Microscopic hematuria Grade 2: Moderate frequency. Intermittent macroscopic hematuria. Grade 3: Severe frequency and dysuria. Frequent hematuria. Reduction in bladder capacity (<150 cc) Grade 4: Necrosis/ Contracted bladder (capacity <100 cc). Severe hemorrhagic cystitis

    Measured: 6 months after trial initiation

  2. Efficacy assessed by the high-grade progression-free rate at 30 days after the last durvalumab instillation and 6 months following durvalumab therapy.

    Measured: 30 days and 6 month after last durvalumab instillation

  3. PD-L1 and VEGF expression assessed in tumor tissue obtained before and after durvalumab instillation

    Immunohistochemistry will be used for the evaluation of PD-L1 and VEGF expression levels

    Measured: 33 months after FPFV

  4. Assessment of PD-L1 and VEGF protein levels in urine samples obtained before and after durvalumab instillation

    Measured: 33 months after FPFV

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Durvalumab in people with Bladder Cancer, run by Hellenic GenitoUrinary Cancer Group at 1 site in Greece.

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 29 inclusion and 20 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 23 Mar 2022. 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 Greece. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

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?

The maximum tolerated dose (MTD) of Durvalumab among 500mg, 750mg and 1000mg that will be given intravesically to patients with BCG-refractory NMIBC (time frame: 6 months after trial initiation). The study lists 3 primary outcomes in all. 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 NCT03759496, 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 23 Mar 2022.
