BOXIT

A randomised, phase III, placebo-controlled trial evaluating the addition of celecoxib to standard treatment of transitional cell carcinoma of the bladder.

Disease site: Bladder cancer, urological cancers

Treatment modality: Systemic therapy

Status: In follow up

Trial details

BOXIT is a randomised, phase III, multicentre, double blind, placebo controlled clinical trial to determine if addition of the oral COX-2 inhibitor celecoxib to standard therapy is more effective in terms of disease recurrence at 3 years compared to standard therapy alone for the treatment of non-muscle invasive transitional cell carcinoma of the bladder in intermediate and high risk patients.

472 patients were recruited from UK sites over a 5 year period. Patients received either 400 mg celecoxib daily for 2 years or placebo, in addition to standard therapy, and are being followed up for up to 10 years.
