"Maximally effective birth control" means that the patient, if sexually active, should be using a combination of 2 methods of birth control that are approved and recognized to be effective by health authorities.\n9. Male patients must be surgically sterile or willing to use 2 highly effective forms of birth control upon enrollment, during the course of the study, and for 1 month following the last study drug instillation.\n10.

Active infection requiring systemic therapy including urinary tract infection (once satisfactorily treated, patients can enter the study).\n5. Active systemic autoimmune disease that required systemic treatment in the past 2 years. Short courses of steroids (≤ 14 days) for medical reasons without anticancer intent (eg, atopic dermatitis, psoriasis, infection, allergic reaction) are permitted if the last dose was ≥ 4 weeks before the first dose of study treatment.\n6. Women who are pregnant or nursing.\n7. Any medical psychological, familial, sociological, or geographical condition that, in the opinion of the Investigator, would preclude participation in the study.\n8. History of malignancy of other organ system within the past 5 years, except previously treated UTUC, basal cell carcinoma or squamous cell carcinoma of the skin, and/or prostate cancer under active surveillance (see inclusion criterion 8).\n9. Patients who cannot tolerate intravesical dosing or intravesical surgical manipulation.\n10. Intravesical therapy within 4 weeks before starting study treatment.\n11.
