Comparison of patient and clinician satisfaction with tirbanibulin treatment’s ability to improve ‘how skin looks’ and ‘skin texture’ in the treated area, among patients with Actinic Keratosis treated with tirbanibulin in community practices across U.S. PROAK Study

Abstract

Introduction: The objective of this analysis was to compare patient and clinician satisfaction with tirbanibulin treatment’s ability to improve ‘how skin looks’ and ‘skin texture’ in the treated area, among patients with Actinic Keratosis (AK) treated with tirbanibulin in community practices across the U.S. Methods: A single-arm, prospective cohort study (PROAK) was conducted among adult patients with AKs on the face or scalp who were newly initiated with once-daily tirbanibulin treatment (5-day course) in real-world community practices in the U.S, as part of usual care. Patients and clinicians completed surveys and clinical assessments at baseline, Week-8 (timeframe for main endpoints) and Week-24. Patient’s self-reported satisfaction and clinician satisfaction with tirbanibulin treatment’s ability to improve ‘how skin looks’ and ‘skin texture’ in the treated area at individual patient-level were assessed among study patients at Week-8 on a seven-point adjectival response scale of 1 (extremely dissatisfied) – 7 (extremely satisfied). Results: A total of 290 patients with AKs completed the study assessments at Week-8 (female: 31.38%; history of skin cancer: 61.72%; Fitzpatrick skin type: I: 7.59%, II: 71.38%, III: 18.62%, IV: 1.38%, V: 1.03%). Patient self-reported skin-texture at baseline was – dry: 39.66%, smooth: 47.59%, rough: 19.66%, bumpy: 18.62%, scaly: 35.17%, blistering/peeling: 6.55%. All patients (100%) completed their 5-day once-daily treatment course. At Week-8, 75.86% & 78.97% of the patients and clinicians respectively reported extremely/very/satisfied with tirbanibulin’s ability to improve ‘how skin looks’, while 14.14% & 14.14% respectively reported somewhat satisfied, and 10.00% & 6.55% respectively reported extremely/very/dissatisfied. At Week-8, 74.83% & 80.69% of patients and clinicians respectively reported extremely/very/satisfied with tirbanibulin’s ability to improve their ‘skin texture’, while 15.52% & 12.41% respectively reported somewhat satisfied, and 9.65% & 6.55% respectively reported extremely/very/dissatisfied. Conclusion: A majority of patients with AKs and their clinicians reported satisfaction with the ability of 5-day treatment course of tirbanibulin to improve ‘how skin looks’ or ‘skin texture’ in the tirbanibulin-treated area, at Week-8.
