NCT04179162

Brief Summary

This study will test the safety of BCG and gemcitabine in people who have BCG-relapsing Non-Muscle Invasive Bladder Cancer (NMIBC). The researchers will test increasing doses of gemcitabine to find the highest dose that causes few or mild side effects when combined with BCG. The study will also look at whether this combination of drugs is effective in treating BCG-relapsing NMIBC.

Outcome Measures

Primary Outcomes (2)

  • evaluate the MTD (Phase I)

    Describe the toxicities by frequency and by grade.This study will use CTCAE version 5.0 for toxicity and serious adverse event reporting.

    1 year

  • proportion of patients who are disease free

    Will be assessed by both urine cytology and cystoscopy at 6 months after initiation of therapy. Disease free (i.e., complete treatment response) is defined as no evidence of disease (negative cytology and cystoscopy).

    6 months after the start of treatment

Study Arms (1)

Bacillus Calmette-Guérin (BCG) and Gemcitabine

EXPERIMENTAL

Eligible patients will receive combination intravesical chemoimmunotherapy. Treatment is sequential, with twice-weekly intravesical gemcitabine given at weeks 1, 4, 7, and 10, for a total of 8 doses, administered in a standard fashion. In phase I, the dose of gemcitabine will depend on the dose level being assessed for the determination of the MTD. phase II, 1 dose level will be given (the MTD from phase I). Fixed doses of once-weekly intravesical BCG therapy (TICE strain, 50 mg) will be given at weeks 2 (+/- 2 days), 3 (+/- 2 days), 5 (+/- 2 days), 6 (+/- 2 days), 8 (+/- 2 days), and 9 (+/- 2 days), for a total of 6 doses, also administered in a standard fashion. All intravesical therapy will be administered in the chemotherapy suite on an outpatient basis, in accordance with standard clinical practice. Intravesical therapies will be retained in the bladder for up to 2 h (BCG) or 1 h (gemcitabine), or as tolerated.

Drug: Bacillus Calmette-Guérin (BCG)Drug: Gemcitabine

Interventions

Patients will receive once-weekly intravesical BCG therapy (TICE strain, 50 mg) at weeks 2 (+/- 2 days), 3 (+/- 2 days), 5 (+/- 2 days), 6(+/- 2 days), 8 (+/- 2 days), and 9 (+/- 2 days).

Bacillus Calmette-Guérin (BCG) and Gemcitabine

Patients will receive gemcitabine at their specified dose level, given in a twice weekly fashion, with 72 to 96 h (+/- 1 day) between doses, at weeks 1, 4, 7, and 10.

  • o Up to 26 months from the last BCG treatment is allowed for the treating physician to perform a transurethral resection of bladder tumor (TURBT) so long as there is evidence of recurrent disease (by positive cytology, imaging, or office cystoscopy) within 24 months of last BCG transurethral resection of bladder tumor (TURBT)
  • Pathologic confirmation of stage, grade, and urothelial histology by the Department of Pathology at MSK
  • All visible papillary lesions macroscopically resected within 60 days of treatment initiation
  • Absence of urothelial carcinoma involving the upper urinary tract (documented by radiological imaging or ureteroscopy) within 12 months from the start of treatment
  • Receipt of restaging transurethral resection (TUR) for any tumor with invasion into the lamina propria (HGT1) as part of standard care
  • Age ≥18 years
  • Karnofsky performance status ≥60%
  • Informed consent

You may not qualify if:

  • Positive pregnancy test
  • Known contraindications to BCG
  • History of systemic hypersensitivity reaction or history of febrile systemic BCG reaction
  • Febrile illness or persistent gross hematuria
  • Active tuberculosis
  • Immunosuppression due to congenital or acquired immune deficiency, concurrent immune suppressive disease, systemic cancer therapy, or chronic immunosuppressive therapy other than topical or inhaled corticosteroids
  • History of or currently being treated for muscle-invasive (i.e., stage T2 or higher) or metastatic urothelial cell carcinoma
  • Evidence of concurrent extravesical (i.e., urethra, ureter, or renal pelvis) urothelial cell carcinoma
  • BCG-unresponsive NMIBC as defined by the FDA:
  • HGT1 within 3 months after an induction BCG course (received ≥5 of 6 doses)
  • Persistent or recurrent high-grade NMIBC (Tis, Ta, T1) within 6 months of ≥5 of 6 doses of induction BCG therapy and ≥2 of 3 doses of maintenance BCG therapy
