BackgroundPsoriasis is most often treated using topical therapies such as the once-daily fixed combination of calcipotriol and betamethasone dipropionate, which is available as a gel and an ointment. To date, there have been no direct comparisons of patient perspectives on the two formulations. ObjectiveTo describe and compare patients' perspectives on calcipotriol and betamethasone gel and ointment formulations, including real-life effectiveness, adherence behaviour, treatment satisfaction and health-related quality of life (QoL), during long-term psoriasis vulgaris management, according to interim findings from the PRO-long study. MethodsPRO-long is a multicentre, prospective, observational, 52-week cohort study in patients prescribed fixed-combination calcipotriol (50g/g) and betamethasone (0.5mg/g; as dipropionate) gel or ointment for long-term psoriasis management. Difference in effectiveness at 4 and 12weeks was assessed by comparing the proportion of patients with controlled (mild or very mild) disease, according to the Patient's Global Assessment. Additional patient questionnaires were used to assess adherence behaviour, treatment satisfaction (nine-item Treatment Satisfaction Questionnaire for Medication) and health-related QoL (Skindex-29). ResultsA total of 156 patients were included in the analysis. In single items of the adherence behaviour and treatment satisfaction questionnaires, patients preferred the gel over the ointment as convenient, easy to use and fast to apply. Post hoc analysis demonstrated significant differences between gel and ointment for convenience and application time. More patients had controlled disease at week 12 with gel (71.9%) vs. ointment (65.7%); however, the difference was not statistically significant (primary end point; P=0.40). ConclusionThis interim analysis supports fixed-combination calcipotriol and betamethasone gel as more convenient, easier to use and faster to apply than the ointment formulation in real-life conditions according to patients with psoriasis vulgaris. Furthermore, a numerical difference in patient-reported real-life effectiveness was seen in favour of the gel, although this was not statistically significant.
