About 75% of bladder cancers are diagnosed as non muscle-invasive and according to specific tumor-stage and grade characteristics, intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) is used to prevent… Read more about this study

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
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients with an intermediary or low risk of progression of bladder cancer (according to an EORTC score and clinical considerations) and thus not requiring BCG immunotherapy will be included after a transurethral resection of the bladder tumor (TURBT). Male and Female patients aged > 18yrs, with a Karnofsky performance status of 60% or more, sero-negative for HIV, HBV and HCV and with laboratory parameters for vital function in the normal range or with abnormalities without clinical significance may be included.

Who cannot join

  • Patients with NMIBC that require BCG treatments or with muscle-invasive bladder cancer, sero-positive for HIV, HBV and HCV or with other serious illnesses (e.g., serious infections requiring antibiotics, bleeding disorders, autoimmune disease), will be excluded.

About this study

Bladder cancer is the fourth and eighth most common malignancy among men and women, respectively. About 75% of bladder cancers are diagnosed as non muscle-invasive and according to specific tumor-stage and grade characteristics, intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) is used to prevent recurrence and/or progression. However, BCG immunotherapy is associated with significant adverse events and treatment failure may occur in 30-40% of cases, hence the necessity for alternative therapies. In an orthotopic MB49 mouse bladder cancer model, another bacterial vaccine (Ty21a/Vivotif) turned out to be more effective than BCG for inducing tumor regression and mice survival upon intravesical instillation; and potentially safer because Ty21a bacteria did not infect/persist in any mice tissues nor in human bladder explants or cell lines, in contrast to BCG. Ty21a/Vivotif has been used in the last 30 years in millions of individuals as an oral typhoid vaccine with a high safety record. In this phase I trial we will be testing the safety of intravesical administration of Ty21a and its effect on bladder immunity in non-muscle invasive bladder cancer (NMIBC) patients, for whom recommendation of BCG therapy is not mandatory.

Read the detailed description

Escalating doses of Ty21a/Vivotif® will be administered by the intravesical route to evaluate whether Ty21 may replace the standard BCG immunotherapy in NMIBC patients.

The minimal starting dose will be instilled intravesically once a week for 4 weeks in 3 patients. If well tolerated, a 5-fold higher dose will be instilled 4-times in 3 other patients, and so on for a maximum of 4 doses to be tested.

The maximal tolerated dose will then be administered to 3 new patients 6-times once a week. If 6 instillations are well tolerated, 7 additional patients will be included to receive 6 instillations with this maximal tolerated dose.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ty21a in people with Non Muscle Invasive Bladder Cancer, run by Patrice Jichlinski at 1 site in Switzerland.

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 1 inclusion and 1 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 28 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 Switzerland. 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?

Results are not available in the source record.

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

Contact denise N Haefliger, PhD (+41213144081, dnardell@hospvd.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse events (time frame: 6 weeks). 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 NCT03421236, 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 28 Apr 2021.
