Summary
Brief summary (as posted)
Because of the high risk for development of muscle invasive disease, cystectomy is recommended for CIS, high-grade Ta and T1 patients who experience disease recurrence following intravesical therapy. VB4-845 injection is an experimental agent that may provide an alternative to cystectomy

Inclusion Criteria: 1. Histologically-confirmed non muscle-invasive urothelial carcinoma (transitional cell carcinoma) of the bladder. 2. Subjects must have received adequate BCG treatment defined as at least 2 courses of BCG, i.e., at least one induction and one maintenance course or at least 2 induction courses. 3. The subject's disease is refractory or has relapsed following adequate BCG treatment. 4. Male or non-pregnant, non-breastfeeding female, age 18 years or older at date of consent. 5. All women of childbearing potential (WOCBP) must have a negative pregnancy test within 7 days of the first dose of study therapy. 6. All sexually active subjects agree to use barrier contraception (i.e., condoms) while receiving study treatment and for 120 days following their last dose of study treatment. 7. Karnofsky performance status ≥ 60. 8. Ability to understand and sign an Independent Ethics Committee-or Institutional Review Board-approved informed consent document. Exclusion Criteria: 1. The subject is pregnant or breastfeeding. 2. Evidence of urethral or upper tract transitional cell carcinoma (TCC) within the past 2 years. 3. Subjects with hydronephrosis, except for those subjects where hydronephrosis has been longstanding and diagnostic evaluation at Screening shows no evidence of tumor. 4. Any intravesicular or other chemotherapy treatment within 2 weeks or any investigational agent within 4 weeks prior to the initial dose of study drug. 5. History of recurrent severe urinary tract infections (UTIs) per investigator judgment. Subjects with a current UTI requiring antibiotic treatment may defer the initiation of Vicinium treatment on Day 1 until resolution of the UTI. 6. he subject has a diagnosis of another malignancy within 2 years before the first dose of study treatment. 7. A QTc interval of \>470 msec by the Fridericia formula (QTcF), at the Screening ECG. 8. Subjects who, in the opinion of the Investigator, cannot tolerate intravesical administration or intravesical surgical manipulation (cystoscopy, biopsy) due to the presence of serious comorbid condition(s). 9. Local or severe allergy to any components of the drug regimen.
