PRIME: Pilot Study Evaluating Percutaneous Vaccination of BCG for Bladder Cancer

Early Phase 1
Completed
Conditions
Bladder Cancer
Interventions
Drug: Bacillus Calmette-Guerin (BCG)
Registration Number
NCT02326168
Lead Sponsor
The University of Texas Health Science Center at San Antonio
Brief Summary

Approximately 25 subjects will be enrolled and receive a standard WHO adult potency BCG immunization (1cc/50mg live mycobacilli) in the deltoid. Following a wait period after BCG vaccination, patients will then receive standard strength BCG intravesical therapy once a week for a total of 6 weeks. The BCG is instilled and held in the bladder for approximately 2 hours. While the BCG is retained in the bladder the patient should be repositioned every 30 minutes to maximize bladder surface exposure to the agent. Patients will undergo a cystoscopy every 3 months following most recent TURBT. Study duration last approximately 6 months.

non-muscle invasive bladder cancerBacillus Calmette-Guerin (BCG)Every patient meeting eligibility criteria will receive a standard WHO adult potency Bacillus Calmette-Guerin (BCG) immunization (1cc/50mg live mycobacilli) in the right or left deltoid. Following a 19 - 31day wait period after BCG vaccination patients will then receive standard strength BCG intravesical therapy returning once a week for 6 consecutive weeks. Cystoscopy will be performed at 3 and 6 months. Interventions: BCG immunization in deltoid and BCG intravesical therapy once a week for 6 weeks.
Primary Outcome Measures
NameTimeMethod
BCG response3 months after baseline

Percentage of patients with complete response at 3 months following therapy of combined percutaneous vaccination with TICE percutaneous Bacillus Calmette-Guerin (BCG) vaccine combined with standard protocol intravesical induction BCG vaccine for patients with non-muscle invasive transitional cell carcinoma of the bladder.

Secondary Outcome Measures
NameTimeMethod
PPD conversion3 months from BCG vaccination

PPD conversion from negative to positive (defined as ≥ 10 mm induration at 48-72 hours following PPD placement).
