Brief summary

Topical steroid therapy is considered the first line of treatment for Oral Inflammatory Ulcerative Diseases with current treatment regimens requiring multiple application or rinses daily. Using Mucolox™ as a vehicle to deliver topical dexamethasone to the oral mucosa has the potential to effectively prolong contact time between the medication. The primary objective of this study is to determine the clinical efficacy and tolerability of compound dexamethasone at 0.5 mg/5 mL in Mucolox™ for the treatment of Oral Inflammatory Ulcerative Diseases as measured by a reduction in oral symptoms between patients treated with compounded dexamethasone 0.5mg/5ml solution in Mucolox™ (group A) and patients treated with topical commercial dexamethasone 0.5mg/5ml solution only (group B). and mucosa, leading to improved clinical outcomes due to the need for less frequent application.

Design outcomes

Primary

MeasureTime frameDescription
Mean Change From Baseline in Oral Pain Scores on the Visual Analog Scale (VAS) at 4 Weeks4 weeksOral Pain Scores were measured on the Visual Analog Scale (VAS), the score ranges from 0-10, zero indicating no pain and 10 indicating the worst pain. The pain score measured on a VAS scale will be compared between group A and group B to detect any significant differences pre and post treatment at 4 weeks.

Secondary

MeasureTime frameDescription
Mean Change From Baseline in Reticulation/Keratosis, Erythema, and Ulceration (REU) Scores at 4 Weeks4 weeksOral lesions were scored using the REU (reticulation,erythema and ulcer) system (form 0 till 49.5). Reticulations were scored from 0 to 1 (0 = no white striations, 1 = presence of white striations or keratotic papules); erythematous lesions from 0 to 3 by area of involvement (0 = no lesion, 1 = lesions less than 1 cm2, 2 = lesions from 1 to 3 cm2, 3 = lesions greater than 3 cm2); ulcers from 0 to 3 by area of involvement. The higher is the score the more severe is the disease. In order to evaluate the clinical improvement in clinician-reported outcome measures for oral lesions, REU scores within the compound dexamethasone solution in Mucolox™ group (Arm A) will be compared to that in the dexamethasone solution only group (Arm B). The REU scores will be summarized descriptively for each arm at pre-treatment, post-treatment, and pre-to-post treatment change. The pre-to-post treatment change will be compared between the arms using either student's t-test o
