Spots Global Cancer Trial Database for Use of Cidofovir for Recurrent Respiratory Papillomatosis

Study Description

Brief Summary: Recurrent respiratory papillomatosis (RRP) is the most common benign neoplasm of the larynx in the pediatric population. The impact of the disease on patients and families can be tremendous due to the need for frequent treatment. It would be highly beneficial to develop effective medical therapies as adjunctive measures to surgical ablation with the goal of reducing the frequency of reoccurrence.

Detailed Description: The focus of the present study is to evaluate the usefulness of cidofovir injection in diminishing the frequency and magnitude of papilloma recurrences in adult and pediatric RRP patients. Briefly, patients will be randomized into either a treatment (cidofovir injection) or a placebo group. The following measures will be made at each of 6 data collection time points, over the course of one year: (1) tumor load, based upon a published staging system for papilloma, (2) degree of respiratory obstruction for phonation, as assessed by phonation threshold pressures, and (3) general health, on validated health inventories (SF12 and Voice Handicap Index for adults; PedsQL (Trademarked) for children) and via measures of height weight and days absent from school or daycare, where applicable, for children. A repeated measures analysis will allow examination of time by treatment interactions to determine if the cidofovir injection group has fewer, or less severe, recurrences than the placebo group. Specifically, we will answer the following questions in this investigation: 1. Does cidofovir injection reduce the frequency of RRP recurrences? 2. Does cidofovir injection reduce the magnitude of RRP, as assessed with a proposed staging system for RRP (Derkay et al., 1998) and measures of phonatory threshold pressure? 3. Does cidofovir injection improve general health, as assessed by height, weight and days absent from school in pediatric patients and health inventories (general health and voice-related) in children and adults?
