A Phase III Randomized Trial to Evaluate the Influence of BCG Strain Differences and T Cell Priming With Intradermal BCG Before Intravesical Therapy for BCG-Naive High-Grade Non-muscle Invasive Bladder Cancer
The primary objectives of this study are to:
1. Compare whether time to high-grade recurrence for patients with BCG-naïve, non-muscle invasive bladder cancer receiving Tokyo-172 BCG strain (Arm 2) is non-inferior to patients receiving BCG LIVE strain (Arm 1).
2.Test whether TTHGR for patients with BCG-naïve, NMIBC receiving intradermal Tokyo-172 BCG vaccination followed by intravesical Tokyo-172 BCG instillation (Arm 3) is superior to patients receiving intravesical Tokyo-172 BCG instillation without prior intradermal BCG vaccination (Arm 2).
- Patients must have histologically proven Ta, carcinoma in situ (CIS) or T1 stage urothelial cell carcinoma of the bladder within 90 days of registration
- Patients must have had all grossly visible papillary tumors removed within 30 days prior to registration or cystoscopy confirming no grossly visible papillary tumors within 30 days prior to registration
- Patients with T1 disease must have cross-sectional imaging of abdomen/pelvis demonstrating no evidence of metastatic disease (magnetic resonance imaging [MRI] or computed tomography [CT] scan) within 90 days prior to registration; patients with T1 disease must have re-resection confirming =< T1 disease within 90 days prior to registration
- Patients must have high-grade bladder cancer as defined by 2004 World Health Organization (WHO)/International Society of Urological Pathology (ISUP) classification
- Patients must not have pure squamous cell carcinoma or adenocarcinoma
- Patients' disease must not have micropapillary components
- Patients must have no evidence of upper tract (renal pelvis or ureters) cancer confirmed by one of the following tests performed within 90 days prior to registration: CT urogram, intravenous pyelogram, magnetic resonance (MR) urogram, or retrograde pyelograms
- Patients must not have nodal involvement or metastatic disease
- No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for five years; patients with localized prostate cancer who are being followed by an active surveillance program are also eligible
- Patients must have a Zubrod performance status of 0-2
- Patients must not have received prior intravesical BCG
- Patients must not have known history of tuberculosis
- Patients must be PPD negative within 90 days prior to registration; PPD negativity is defined as < 10 mm diameter induration (palpable, raised hardened area) in the volar forearm at 48-72 hours following injection with standard tuberculin dose (5 units, 0.1 ml)
- Patients must be >= 18 years of age
- Patients must not be taking oral glucocorticoids at the time of registration
- Patients must not be planning to receive concomitant biologic therapy, hormonal therapy, chemotherapy, surgery, or other cancer therapy while on study
- Prestudy history and physical must be obtained within 90days prior to registration
- Patients must not be pregnant or nursing; women/men of reproductive potential must have agreed to use an effective contraceptive method; a woman is considered to be of "reproductive potential" if she has had menses at any time in the preceding 12 consecutive months; in addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation; however, if at any point a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures
- Patients must be offered the opportunity to participate in specimen banking for future studies to include translational medicine studies
