About

The purpose of the study is to assess, at control visit (V8), the ablative activity of intravesical administration of Oncofid-P-B on a papillary marker tumor on patients suffering from multiple primary and recurrent Ta G1-G2 papillary cancer of the bladder after 6 weeks of weekly study drug administration, through number and percentage of patients with Complete Response.

Full description

This study will investigate the preliminary activity of Oncofid-P-B administered by intravescical route at the Recommended Dose of 600 mg, once a week, for six weeks evaluating the ablative activity on a papillary marker tumor in patients suffering from non-muscle invasive cancer of the bladder. When a patient will present a Complete Response at the end of the six weekly administration of Oncofid-P-B , he/she can enter a second phase of the study defined maintenance phase. During this phase, the patients will be treated with the study drug administered by intravesical infusion once a month for 2 cycles of treatment with the duration of 6 months separated by a period during which study drug will not be administered, due to the necessity to perform histological evaluation of efficacy. This scheme will follow a clinical usual approach for the maintenance treatment of patients suffering from non-muscle invasive cancer of the bladder.

Complete Response is defined as follows: complete disappearance of the marker lesion, as confirmed by negative post-treatment cystoscopy including a biopsy at the marker lesion site and the absence of new tumors at other site and negative cytology.
