Brief Summary

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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.

You may not qualify if:

  • 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.
