Phase I-II evaluation of intravesical novantrone (mitoxantrone) in superficial bladder cancer.
The objective of this study was to determine the safety and efficacy of intravesical novantrone in refractory superficial bladder cancer. The eligibility criteria included proven carcinoma in situ or superficial transitional cell carcinoma of the bladder at stage Ta or T1 that was proven refractory to or in relapse after the use of at least one other standard anti-cancer agent. The patient was to have received no prior radiotherapy or intravesical therapy for at least 4 weeks prior to entry. Patients also did not suffer significant cardiac dysfunction, such as angina, congestive heart failure, or uncompensated cardiomyopathy. All patients were given 4-6 doses of intravesical novantrone at the same dose level at weekly dosing interval. Patients were required to retain the drugs in the bladder for 2 h. Baseline study included history/physical, hematology, blood chemistry, cystoscopy, bladder barbotage, urine cytology, cystometrogram to assess the bladder capacity, and finally, chest X-ray, EKG, and MUGA scan, if indicated. Weekly assessment involved toxicity notation, blood chemistry, hematology and urinalysis. Monthly assessment included physical examination, toxicity notation, hematology, urinalysis and blood chemistry. Within 4 weeks of completion of the last dose, patients underwent repeat cystoscopy to assess disease status. Patients who responded to the 4-6 week induction phase were entered in a monthly dose regimen for up to 5 months. A total of 23 patients were enrolled: 22 males and 1 female. One patient dropped out before receiving medication because of a protocol violation for entry criteria. Twenty-two patients were eligible for assessment of safety and 20 were eligible for assessment of efficacy.(ABSTRACT TRUNCATED AT 250 WORDS)
