Alternate Title

Radiation Therapy With or Without Carbogen and Niacinamide in Treating Patients With Bladder Cancer

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase III Treatment Closed Over 18 Other MTVERNHOSP-BCON EU-20051, NCT00033436

Objectives

1. Compare the 6-month cystoscopic response in patients with locally advanced transitional cell carcinoma of the bladder treated with radical radiotherapy with or without radiosensitization with carbogen and niacinamide.
2. Compare the local failure-free and overall disease-specific survival of patients treated with these regimens.
3. Compare the treatment-related morbidity, in particular acute and chronic bowel and bladder symptoms, in patients treated with these regimens.
4. Compare the quality of life of patients treated with these regimens.

Entry Criteria

Disease Characteristics:

• Histologically confirmed transitional cell carcinoma of the bladder
  • Muscle invasive carcinoma (stage T2 or T3) of any grade

Patient Characteristics:

Age:

Life expectancy:

Hematopoietic:

• Not specified

Hepatic:

Renal:

Cardiovascular:

• No ischemic heart disease or peripheral vascular disease requiring diuretics or angiotensin-converting enzyme inhibitors

Pulmonary:

• No concurrent respiratory disease with reduced respiratory drive that would preclude the delivery of 95% oxygen

Other:

• Capable of complying with a closed breathing system delivering carbogen through either a mask or a mouthpiece with nasal clip

Expected Enrollment

A total of 330 patients (165 per treatment arm) will be accrued for this study.

Outcomes

Cystoscopic response at 6 months after initiation radiotherapy
Local failure-free survival
Overall disease-specific survival

Treatment related morbidity (i.e., acute and chronic bowel and bladder symptoms)
Quality of life as assessed by FACT-BI scale at baseline, week 4, 3 months, 6 months, 12 months, and yearly thereafter for 5 years

Outline

This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive radical radiotherapy once daily, 5 days a week, for 4-6.4 weeks. Patients also receive oral niacinamide once daily 1.5-2 hours before initiation of each radiotherapy dose and carbogen through a closed breathing system (face mask with a tight air seal or a mouthpiece with nasal clip) once daily beginning 5 minutes before initiation and continuing until completion of each radiotherapy dose.



• Arm II: Patients receive radiotherapy as in arm I.

Quality of life is assessed at baseline; at 4 weeks; at 3, 6, and 12 months; and then annually for 4 years.

Patients are followed at 8 and 12 weeks; at 6, 9, and 12 months; and then every 6 months for 4 years.
