Bacillus Calmette-Guérin (BCG) and Gemcitabine in People With High-Grade Non-Muscle Invasive Bladder Cancer That Came Back After BCG Treatment

Phase 1

Recruiting

• Conditions: Non-Muscle Invasive Bladder Cancer (NMIBC)
• Interventions: Drug: Bacillus Calmette-Guérin (BCG); Drug: Gemcitabine

• Registration Number: NCT04179162
• Lead Sponsor: Memorial Sloan Kettering Cancer Center

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.

Inclusion Criteria

• Recurrent for persistent high-grade NMIBC Ta/T1/Tis (Ta/T1 with CIS is preferred, but not required) within 24 months of the last treatment with BCG (with or without IFN)

  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

Exclusion Criteria

• 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

Arm && Interventions

Group	Intervention	Description
Bacillus Calmette-Guérin (BCG) and Gemcitabine	Bacillus Calmette-Guérin (BCG)	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.

Primary Outcome Measures

Name	Time	Method
evaluate the MTD (Phase I)	1 year	Describe the toxicities by frequency and by grade.This study will use CTCAE version 5.0 for toxicity and serious adverse event reporting.
proportion of patients who are disease free	6 months after the start of treatment	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).
