The aim of this phase III study is to assess the efficacy of abnobaVISCUM® 900 compared with
Mitomycin C (MMC) monotherapy in patients with superficial bladder carcinoma by evaluation of
the time to tumor recurrence. Secondary objective is to evaluate the safety of abnobaVISCUM®
900, in particular, to compare the toxicity of the two treatments. Another secondary
objective is the treatment efficacy as measured by calculated prognosis for recurrence and
progression after 1 year, the tumor grading in case of a recurrence and by measurement of
Quality of Life.
