IMPORTANCE

Symptomatic oral lichen planus (OLP) can be challenging to treat.

OBJECTIVE

To compare the efficacy of oral acitretin plus topical triamcinolone acetonide (TAC), 0.1%, with TAC monotherapy in patients with symptomatic OLP.

DESIGN, SETTING, AND PARTICIPANTS

This monocentric, investigator-initiated, placebo-controlled, investigator- and patient-blinded randomized clinical trial was conducted from December 2018 to June 2020 at the Postgraduate Institute of Medical Education and Research, a tertiary referral center in Chandigarh, India. Sixty-four patients 18 years or older with symptomatic OLP were recruited by consecutive sampling. Data were analyzed from July to December 2020.

INTERVENTION

The patients were randomized to receive either a combination of oral acitretin (25-35 mg/d) and TAC (treatment group) or TAC in combination with placebo (placebo group) for 28 weeks, with an additional 8 weeks of treatment-free follow-up after the end of treatment (36 weeks of total study duration).

MAIN OUTCOMES AND MEASURES

The disease severity and treatment response were assessed using Oral Disease Severity Score (ODSS), Oral Health Impact Profile 14 (OHIP-14), and visual analog scale (VAS). The primary aim was to assess the number of patients achieving ODSS-75 (75% reduction in ODSS compared with baseline) in both groups at 28 weeks and at the end of 36 weeks.

RESULTS

Among 64 patients, 31 in the treatment group and 30 in the placebo group completed the study (mean [SD] age, 50.6 [15.2] years vs 49.2 [14.4] years; male-female ratio, 13:19 vs 16:16). Baseline ODSS, visual analog scale, and Oral Health Impact Profile 14 scores were comparable in both groups. In the intention-to-treat analysis, there was a statistically significant higher number of patients achieving 75% or higher reduction in ODSS in the treatment group compared with the placebo group at the end of 28 weeks (28 [88%] vs 15 [47%], a 41 [95% CI, 20-61] percentage point difference between groups; P < .001; Cramér V = 0.47) and 36 weeks (27 [84%] vs 13 [41%], a 43 [95% CI, 23-67] percentage point difference between groups; P < .001; Cramér V = 0.47). Relapses during the posttreatment follow-up of 8 weeks were low among patients in both treatment and placebo groups (1 [3%] vs 2 [6%], a 3 [95% CI, -13 to 7] percentage point difference between groups; P > .99; Cramér V = 0.07).

CONCLUSION AND RELEVANCE

In this randomized clinical trial, the combination of oral acitretin and TAC was more effective than TAC monotherapy in patients with symptomatic OLP.
