Clinical evaluation of MGI 209, an anesthetic, film-forming agent for relief from painful oral ulcers associated with chemotherapy.
OBJECTIVE
This open-label, multicenter trial evaluated the efficacy of a mucoadherent, anesthetic medication (MGI 209) for relief from painful oral ulcers associated with cytotoxic chemotherapy.


METHODS
Twenty-eight eligible cancer patients who had up to five discrete oral ulcers (total area < or = 5 cm2) completed this study. Mean age was 53.5 years (range, 21 to 81). Subjective assessments of oral discomfort before and after an orange juice pain challenge (OJPC), which was measured using a visual analog scale (VAS), and visual estimates of the amount of MGI 209 that remained on treated ulcers were collected at (1) baseline (before MGI 209 treatment); and (2) 30, 60, 120, and 180 minutes posttreatment.


RESULTS
Most subjects had low VAS scores (4 or less), which was indicative of oral discomfort, at baseline before and after the OJPC. At 30, 60, 120, and 180 minutes after MGI 209 treatment, most subjects had high VAS scores before and after an OJPC compared with baseline scores, which was indicative of a substantial increase in oral comfort; these differences were statistically significant (P < .0001). Mean percent of MGI 209 estimated to remain on ulcers at the previously mentioned times was 93.7%, 90.3%, 79.6%, and 71.3% of the total amount applied, respectively.


CONCLUSIONS
Benzocaine hydrochloride in combination with the protective, mucoadherent film-coating relieved discomfort for at least 3 hours even with exposure to an irritating beverage. MGI 209 treatment should allow patients with chemotherapy-induced oral ulcers to drink and eat with significantly diminished pain or no pain.
