Trial Outcomes & Findings for A Clinical Study of Curcuminoids in the Treatment of Oral Lichen Planus (NCT NCT00525421)

NCT ID: NCT00525421

Last Updated: 2013-08-07

Results Overview

Numeric Rating Scale (NRS) is patient-reported numerical score for intensity of symptoms (range 0-10, where 0=no oral discomfort and 10=worst imaginable oral discomfort; symptom score over the last 1 week was recorded at baseline, and symptom score since baseline was recorded at follow-up. For Modified Oral Mucositis Index (MOMI) each of 16 oral sites is scored by an examiner for both erythema intensity (range 0-3 where 0=normal, 1=mild, 2=moderate, 3=severe) and area of ulceration (range 0-3 where 0=none, 1=\>0-0.25 cm\^2, 2= \>0.25-1 cm\^2, 3=\>=1cm\^2): right (R) and left (L) buccal mucosa, labial mucosa (upper and lower), lateral tongue (R and L), dorsum of tongue (R and L), ventral tongue and floor of mouth (R and L), maxillary gingiva (R and L), mandibular gingiva (R and L), and soft and hard palate. Total score for clinical signs (MOMI) is the sum of scores for 16 sites; separate scores for erythema and ulceration are the sums of respective scores.

Participant Flow

23 patients with symptomatic oral lichen planus (OLP) presenting to the oral medicine clinic at the University of California, San Francisco (UCSF) between October 2007 and November 2008 were screening for this study.

3 patients had elevated liver enzymes at baseline and were excluded prior to randomization
