Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Superficial Bladder Cancer Drug: abnobaVISCUM 900 Drug: Mitomycin C Phase 3

Detailed Description:

This is a randomized, open-label, active-controlled, prospective, multinational Phase III confirmative study with 2 treatment groups and an adaptive design (Bauer and Köhne, 1994). The study is designed to compare the efficacy of treatment with abnobaVISCUM® 900 with Mitomycin C (MMC). Patients with completely resected superficial bladder carcinoma (Stage Ta) with an intermediate risk classification according to the European Association of Urology (EAU, update 2013) and with one immediately post operative MMC 40 mg intravesical instillation will be eligible for inclusion in the study.

The study comprises a screening period of not more than 6 weeks, a treatment period of 12 months for abnobaVISCUM® 900 and MMC and a follow-up period of 12 months. Patients will be screened within 6 weeks after the transurethral resection of the bladder (TURB) and the immediately post operative MMC 40 mg intravesical instillation. A re-resection should be performed before inclusion if indicated. Every patient is to provide written informed consent before any study related procedures will be performed.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Time to tumor recurrence [ Time Frame: up to two years ]
    The primary objective of the study is to assess the efficacy of abnobaVISCUM® 900. Primary efficacy criterion will be the time to tumor recurrence.


Secondary Outcome Measures :
  1. Toxicity and tolerability of the study medication [ Time Frame: up to two years ]
    The secondary objective, namely safety including toxicity and tolerability of the study medication, will be assessed by the monitoring of adverse events (AEs) according to the Common Terminology Criteria for Adverse Events (CTCAE), laboratory assessments (hematology, biochemistry and urinalysis) and a global judgment of tolerability.

  2. Prognosis after 1 year for recurrence and progression [ Time Frame: 1 year ]
    A secondary efficacy endpoint is prognosis after 1 year for recurrence and progression, estimated by the European Organization for Research and Treatment of Cancer (EORTC) Bladder Cancer Calculator.

  3. Quality of Life with the EORTC QLQ-C30 and BLS24 Quality of Life Questionnaires [ Time Frame: up to two years ]
    A secondary efficacy endpoint is measurement of Quality of Life with the EORTC QLQ-C30 and BLS24 questionnaires.

  4. Tumor grading [ Time Frame: up to two years ]
    A secondary efficacy endpoint is the tumor grading in case of a recurrence by cytology, ultrasound, and cystoscopy.
