Vicinium Treatment for Subjects With Non-muscle Invasive Bladder Cancer Previously Treated With BCG
United States133 participantsStarted 2015-08
Plain-language summary
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. Vicinium is an experimental agent that may provide an alternative to cystectomy

Inclusion criteria
✓. Histologically-confirmed non muscle-invasive urothelial carcinoma (transitional cell carcinoma) of the bladder as follows:
✓. CIS (with or without papillary disease) OR
✓. Any grade T1 papillary disease OR
✓. High-grade Ta papillary disease based on a biopsy within 8 weeks of the initial dose of study treatment. If multiple bladder biopsies are required to confirm eligibility, the last bladder biopsy to the initial dose of study treatment must be within 8 weeks. This diagnosis must be confirmed by the independent central pathology reviewer prior to subject enrollment. A subject with persistent T1 disease on the second (i.e., restaging) TURBT may be enrolled in this study only if the investigator documents the subject declines cystectomy.
✓. 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. The initial induction course must be at least 5 treatments within a 7-week period. The second course (induction or maintenance) must be at least 2 treatments within a 6-week period. The "5+2" doses of BCG must be given within approximately 1 year (i.e., the start of one course to start of the second course within 12 months ±1 month) and for the same disease episode for which the subject is enrolling. Treatment must be considered "full-dose" BCG (see Section 10). If additional doses or courses of BCG above the minimum "5+2" are given, these do not have to be within the same approximate 12 month timeframe.
✓. The subject's disease is refractory or has relapsed following adequate BCG treatment. Refractory disease is defined as disease which persists at the first evaluation following adequate BCG. Relapsed disease is defined as having a complete response to adequate BCG but recurs at a subsequent evaluation.
✓. Male or non-pregnant, non-breastfeeding female, age 18 years or older at date of consent.
. All women of childbearing potential (WOCBP) must have a negative pregnancy test within 7 days of the first dose of study therapy. A woman is not of childbearing potential if she has undergone surgical sterilization (bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy) or if she is ≥55 years of age and has had no menstrual bleeding of any kind including menstrual period, irregular bleeding, spotting, etc., for at least 12 months and there is no other cause of amenorrhea (e.g., hormonal therapy, prior chemotherapy).
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.
