Phase II Study of Intravesical Therapy With AD 32 in Patients With Papillary Urothelial Carcinoma or Carcinoma in Situ (CIS) Refractory to Prior Therapy With Bacillus Calmette-Guerin

OBJECTIVES:

• Determine the recurrence rate and disease free survival in patients with recurrent or refractory papillary transitional cell carcinoma of the bladder with or without carcinoma in situ of the bladder treated with intravesical AD 32.
• Evaluate the safety of administering this drug in these patients.
• Determine the effectiveness of this drug, in terms of recurrence rates and disease free survival, in these patients.

OUTLINE: Patients are stratified according to cellular diagnosis (papillary transitional cell carcinoma (Ta/T1) with no carcinoma in situ (Tis) vs Tis with or without Ta/T1).

Patients receive intravesical AD 32 once a week for 6 weeks.

Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.
