Vicinium Treatment for Subjects With Non-muscle Invasive Bladder Cancer Previously Treated With BCG

Exclusion criteria

• . The subject is pregnant or breastfeeding.
• . Evidence of urethral or upper tract transitional cell carcinoma (TCC) within the past 2 years. Subjects with T1 disease must have no evidence of upper or lower tract disease or a more advanced stage of disease by CT urogram or MRI urogram of the abdomen and pelvis performed within 8 weeks of the first dose of study treatment. If intravenous contrast is contraindicated, retrograde ureteropyelography, or CT or MRI without intravenous contrast may be performed.
• . Subjects with hydronephrosis, except for those subjects where hydronephrosis has been longstanding (i.e., predates the diagnosis of the CIS, Ta or T1 by more than 2 years) and diagnostic evaluation at Screening shows no evidence of tumor. Subjects with hydronephrosis that is unequivocally unrelated to upper tract malignancy may be considered eligible with Sponsor approval.
• . Any intravesicular or other chemotherapy treatment within 2 weeks or any investigational agent within 4 weeks prior to the initial dose of study drug.
• . 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 (even if this extends the screening period requirements to start of Vicinium treatment).
• . Active, uncontrolled impairment of the urogenital, renal, hepatobiliary, cardiovascular, gastrointestinal, neurologic or hematopoietic systems which, in the opinion of the Investigator, would predispose the subject to the development of complications from the administration of intravesical therapy and/or general anesthesia.
• . The subject has a diagnosis of another malignancy within 2 years before the first dose of study treatment, except for superficial skin cancer or localized solid tumors deemed cured by surgery and not treated with systemic anticancer therapy and not expected to require anticancer therapy in the next 2 years i.e., while the subject may be taking study treatment. However, subjects with low-risk prostate cancer, e.g.:
• . A QTc interval of \>470 msec by the Fridericia formula (QTcF), at the Screening ECG. If the subject's QTcF is \>470 msec on the initial ECG, a total of 3 ECGs should be obtained at least 3 minutes apart and all within 30 minutes. The average of the 3 QTcF's will be used to determine eligibility. Known or suspected causes of prolonged QTc can be treated (e.g., hypocalcemia, hypokalemia, hypomagnesimia) and the ECGs may be repeated. If the subject initiates treatment with a drug known to prolong the QTc during the Screening period after the initial Screening ECGs were obtained, the Screening ECGs must be repeated once the new drug has reached steady state to ensure the average QTcF remains ≤470 msec. For subject's whose heart rate is \<60 bpm, the Bazett correction formula (QTcB) may be used.
