Exclusion criteria
Exclusion criteria: 1. Greater than or equal to T1GIII bladder cancer 2. Carcinoma in situ (CIS) 3. Active tuberculosis 4.

History of other active malignancy within five years, except adequately treated basal cell and squamous cell carcinoma of the skin 6. Other serious illness or medical conditions (e.g. history of significant cardiac or respiratory dysfunction) 7. Patients with a contra-indication preventing apheresis 8. History of autoimmune-related disorder 9. Known hypersensitivity to any of the components of the study drugs (e.g. dimethylsulphoxide [DMSO]) 10. Immunosuppression or congenital or acquired immune deficiencies, whether due to concurrent disease (e.g. acquired immune deficiency syndrome [AIDS], leukaemia, lymphoma), cancer therapy (cytotoxic drugs, radiotherapy) or immunosuppressive therapy (e.g. corticosteroids, cyclosporin) 11.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Phase II: To demonstrate a superior safety profile of Bexidem® with respect to FILAEs compared to BCG therapy. Phase III: To compare efficacy (recurrence-free survival) of Bexidem® therapy to BCG therapy. The comparison of toxicity will be performed after all patients in the Phase II step have completed all cycles of treatment and at least three months of follow up (month 9). The recurrence-free survival in each group will be estimated after all Phase II patients have completed at least six months of follow up after the last treatment (month 12 visit). These analyses will serve as the basis for a decision to proceed to the Phase III step as well as to estimate the expected recurrence-free survival in the two groups and recalculate the sample size required for the Phase III step. | — |
Secondary
| Measure | Time frame |
|---|---|
| Phase II: To evaluate overall efficacy and recurrence-free survival in patients treated with Bexidem® therapy. Phase III: To evaluate overall safety of Bexidem® therapy as compared to BCG. The comparison of toxicity will be performed after all patients in the Phase II step have completed all cycles of treatment and at least three months of follow up (month 9). The recurrence-free survival in each group will be estimated after all Phase II patients have completed at least six months of follow up after the last treatment (month 12 visit). These analyses will serve as the basis for a decision to proceed to the Phase III step as well as to estimate the expected recurrence-free survival in the two groups and recalculate the sample size required for the Phase III step. | — |
