The objective of this study was to evaluate the safety and efficacy of single-agent dexamethasone or tacrolimus topical solution as first-line treatment for symptomatic oral chronic graft-versus-host disease (cGVHD). This was a prospective, single-center, open-label, randomized phase II trial of patients with symptomatic oral cGVHD without prior topical therapy. Subjects were randomly assigned 1:1 to either topical dexamethasone (.5 mg/mL) or tacrolimus (.5 mg/mL) solution and instructed to rinse with 5 mL for 5 minutes, 4 times a day, for 4 weeks. Oral cGVHD assessments (National Institutes of Health [NIH] criteria) were completed at baseline and end of treatment (NIH criteria, global response, and tolerability). The primary endpoint was the response rate defined as >= 3-point reduction in patient-reported sensitivity score (range, 0 to 10). A parallel 2-stage design was employed so that a less efficacious arm could be terminated early. The accrual goal was 60 evaluable patients; 30 in each arm), accruing 14 in the first stage and 16 in the second stage. If both arms were regarded as efficacious, a pick-the-winner method would be employed to choose a better treatment for future investigation. Forty-six subjects were randomized to receive either dexamethasone (n = 28) or tacrolimus (n = 18). Six subjects were excluded from the analysis because of changes in systemic immunosuppression (dexamethasone = 1, tacrolimus =3) or lack of end-of-treatment visit (1 per arm). After the first stage evaluation, the tacrolimus arm was terminated because of lack of activity (3 of 14 responses; response rate, 21%). Twenty-six subjects in the dexamethasone arm completed both study visits and were included in the response analysis, with a 58% (15 of 26) response rate, compared with 21% (3 of 14) in the tacrolimus arm (P = .05). The response rates according to the NIH score in the dexamethasone and tacrolimus arms were 50% (13 of 26) and 2% (2 of 14), respectively (P = .04). From the onset of therapy, 31% versus 21% patients reported feeling much better and 38% versus 36% reported feeling slightly better, giving an overall global response rate (much better or slightly better) of 81% (21 of 26) versus 71% (10 of 14), in the dexamethasone and tacrolimus arms, respectively. Dexamethasone rinses were well tolerated and taste was reported as very pleasant or tolerable in most subjects (96%). Intensive topical therapy with dexamethasone solution is effective for managing patients with new-onset symptomatic oral cGVHD and should be considered for first-line therapy. Topical tacrolimus solution appears less effective, at least for first-line therapy. (C) 2016 American Society for Blood and Marrow Transplantation.
