VB4-845 injection is an experimental agent that may provide an alternative to cystectomy', 'detailedDescription': 'Bladder cancer is the 6th most common cancer in the United States, affecting more men than women. The usual first treatment for NMIBC (Ta, T1,and CIS) is transurethral resection of the bladder tumors followed by intravesical immunotherapy, most commonly with bacillus Calmette-Guérin (BCG).\n\nBecause of the high risk for development of muscle invasive disease, cystectomy is recommended for CIS and high-grade Ta and T1 patients who experience disease recurrence following intravesical therapy. For patients unable or unwilling to undergo cystectomy, treatment options are limited.\n\nVB4-845 injection is a recombinant fusion protein produced in Escherichia coli (E. coli) that expresses a humanized single-chain antibody fragment specific for the epithelial cell adhesion molecule (EpCAM) antigen linked to exotoxin A (ETA\\[252-608\\]). Once bound to the EpCAM antigen on the surface of carcinoma cells, Vicinium is internalized through an endocytic pathway. The ETA(252-608) is cleaved off and induces cell death by irreversibly blocking protein synthesis.\n\nThis is an open-label, non-randomized, multicenter bridging study in Chinese patients with NMIBC, specifically CIS (with or without papillary disease), high-grade Ta or any grade T1 papillary disease, who have previously failed BCG treatment (i.e., not those who are intolerant) with or without interferon. The study consists of a Screening period, a 12-week Induction Phase, and a Maintenance Phase of up to 21 monthly cycles for a total treatment period of up to104 weeks.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1. Histologically-confirmed non muscle-invasive urothelial carcinoma (transitional cell carcinoma) of the bladder.\n2.

The subject's disease is refractory or has relapsed following adequate BCG treatment.\n4. Male or non-pregnant, non-breastfeeding female, age 18 years or older at date of consent.\n5. All women of childbearing potential (WOCBP) must have a negative pregnancy test within 7 days of the first dose of study therapy.\n6.

The subject is pregnant or breastfeeding.\n2. Evidence of urethral or upper tract transitional cell carcinoma (TCC) within the past 2 years.\n3. Subjects with hydronephrosis, except for those subjects where hydronephrosis has been longstanding and diagnostic evaluation at Screening shows no evidence of tumor.\n4. Any intravesicular or other chemotherapy treatment within 2 weeks or any investigational agent within 4 weeks prior to the initial dose of study drug.\n5. 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.\n6. he subject has a diagnosis of another malignancy within 2 years before the first dose of study treatment.\n7. A QTc interval of \\>470 msec by the Fridericia formula (QTcF), at the Screening ECG.\n8. 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).\n9.
