Non-invasive clinical and microscopic evaluation of the response to treatment with clobetasol cream vs. calcipotriol/betamethasone dipropionate foam in mild to moderate plaque psoriasis: an investigator-initiated, phase IV, unicentric, open, randomized clinical trial.

ABSTRACT:

Background

Treatment response for psoriasis is typically evaluated using clinical scores. However, patients can relapse after clinical clearance, suggesting persistent inflammation. Dermoscopy, reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) can non-invasively improve treatment response assessment.

Objectives

To compare the clinical and non-invasive microscopic features in a psoriatic target lesion treated with clobetasol cream or calcipotriol/betamethasone dipropionate foam (Cal/BD foam).

Methods

Prospective, unicentric, open, randomized clinical trial comparing clinical data [total clinical score (TCS)] and microscopic data (dermoscopy, RCM and OCT) in psoriasis patients treated with clobetasol or Cal/BD foam.

Results

We included 36 adult patients (22 men). At week 4, more patients treated with Cal/BD foam achieved TCS ?1 than with clobetasol (63.2% vs. 18.8%, P = 0.016). Treatment satisfaction was higher with Cal/BD foam (P < 0.03). Microscopically, Cal/BD foam induced more reduction in epidermal thickness at week 4 (P < 0.049). Dilated horizontal blood vessels were more common with clobetasol than with Cal/BD foam at week 8 (69.2% vs. 31.2%, P = 0.159). If epidermal hyperplasia was noted at baseline, the response was poorer with clobetasol (P = 0.029).

Limitations

Small sample size, open study, imaging sampling bias.

Conclusion

Cal/BD foam is more effective than clobetasol, has better patient satisfaction and induces greater reduction in the hyperkeratosis/acanthosis, regardless of baseline epidermal hyperplasia.

Project description:IntroductionGood treatment adherence is important in the effective management of psoriasis and is related to both the frequency of applications and the amount of product used versus the recommended dose. The efficacy and safety of fixed combination calcipotriol 50 µg/g (Cal) and betamethasone 0.5 mg/g as dipropionate (BD) in the treatment of psoriasis is well established; an aerosol foam formulation has been developed to enhance adherence. This subanalysis from the Phase III PSO-FAST study evaluates the amount of Cal/BD foam used during treatment and the association between the extent and severity of baseline disease.MethodsPatients (≥18 years) with mild-to-severe body psoriasis were randomized 3:1 to once-daily Cal/BD foam or vehicle. The amount of Cal/BD foam and vehicle used over the 4-week study period was evaluated according to three baseline disease assessments: extent of body surface area (BSA) affected by psoriasis, physician's global assessment of disease severity (PGA) and modified psoriasis area and severity index (mPASI). Treatment success and mPASI75 rates were assessed according to body mass index (BMI) and body weight.Results323 patients were randomized to Cal/BD foam and 103 to vehicle. At week 4, the mean total amount of Cal/BD foam used was 120.8 g (n = 293), which was similar to the amount of vehicle used (128.9 g; n = 98). The total amount of Cal/BD foam used at week 4 was greater with increasing BSA and increasing severity of baseline PGA and mPASI. Throughout the study, 93.1% of patients in the Cal/BD foam group and 99.0% of patients in the vehicle group missed ≤10% of treatment applications. Treatment success and mPASI75 rates were generally similar when stratified according to BMI and body weight.ConclusionsThis subanalysis demonstrates that Cal/BD aerosol foam is used appropriately and is effective for the treatment of psoriasis, independent of BMI and the extent or severity of disease.Clinical trials numberNCT01866163.FundingLEO Pharma A/S.

Project description:An aerosol foam formulation of fixed combination calcipotriol 50 ?g/g (Cal) and betamethasone 0.5 mg/g (as dipropionate; BD) has been developed for psoriasis vulgaris treatment.To compare Cal/BD aerosol foam pharmacodynamic activity with Cal/BD ointment and with other topical corticosteroids of different potencies by assessing vasoconstrictor potential.A Phase I, single-centre, investigator-blinded, vehicle-controlled, intra-individual comparison vasoconstriction study. Healthy volunteers received a single application on selected sites of: Cal/BD aerosol foam, clobetasol propionate 0.5 mg/g cream (CP; very potent), Cal/BD ointment (potent), fluocinolone acetonide 0.25 mg/g ointment (FA; moderately potent), BD aerosol foam and aerosol foam vehicle. A seventh untreated site acted as a negative control. Skin blanching was assessed by visual (primary response criterion) and colorimetric a* and L* measurements (secondary criteria), and was analysed over time (6-32 h post-application).Thirty-five healthy volunteers were included. All active treatments led to significantly greater skin blanching than control. By visual assessment, skin blanching with Cal/BD aerosol foam was significantly less compared with CP cream [mean AUC0-32 2560 vs. 3831; mean difference = -1272; 95% confidence interval (CI): -1598, -945; P < 0.001], similar to BD aerosol foam (mean AUC0-32 2560 vs. 2595; mean difference = -35; 95% CI: -362, 292; P = 0.83) and significantly greater than Cal/BD ointment (mean AUC0-32 2560 vs. 2008; mean difference = 552; 95% CI: 225, 878; P = 0.001) and FA ointment (mean AUC0-32 2560 vs. 1981; mean difference = 578; 95% CI: 251, 905; P < 0.001). Colorimetric assessments a* and L* also indicated significantly reduced skin blanching with Cal/BD aerosol foam compared with CP cream. No adverse events (AEs) were reported.Cal/BD aerosol foam can be considered a more potent formulation than Cal/BD ointment and the moderately potent FA ointment, but less potent than the very potent corticosteroid, CP cream.

Project description:BackgroundPlaque psoriasis has significant impact on patients' quality of life. Topical therapy is considered the treatment mainstay for mild-to-moderate disease according to guidelines. Calcipotriol/betamethasone dipropionate (Cal/BD) [0.005%/0.05%] aerosol foam is indicated for psoriasis vulgaris treatment in adults. Cal/BD foam trials demonstrated improved efficacy and similar safety in this population. Psoriasis treatment is complicated by the broad range of disease presentation, variability and therapeutic options; particularly decisions on transition from topical to non-biologic systemic treatment are difficult. Assessing comparative effectiveness of treatment options provides meaningful value to treatment decisions.ObjectiveTo compare efficacy of Cal/BD foam individual patient data from pooled trials with efficacy of non-biologic systemic treatments based on aggregated patient characteristics and treatment outcomes.MethodsIndividual data from four Cal/BD foam trials in 749 psoriasis patients were pooled to conduct matching-adjusted indirect comparisons. Literature review identified non-biologic systemic treatment trials where methods, populations and outcomes align with Cal/BD foam trials. Of 3090 screened publications, four studies of apremilast, methotrexate, acitretin or fumaric acid esters (FAE) were included.ResultsAfter baseline matching, patients treated with 4 weeks of Cal/BD foam had greater Physician's Global Assessment 0/1 response compared to those treated with 16 weeks of apremilast (52.7% vs. 30.4%; P < 0.001). Patients treated with Cal/BD foam had significantly greater Psoriasis Area and Severity Index (PASI) 75 response at Week 4 compared to 16 weeks of apremilast treatment (51.1% vs. 21.6%; P < 0.001). Cal/BD foam patients demonstrated significantly greater PASI 75 response improvements at Week 4 vs. 12 weeks of methotrexate (50.8% vs. 33.5%; P < 0.001) or acitretin (50.9% vs. 31.7%; P = 0.009), and comparable response to FAE (42.4% vs. 47.0%; P = 0.451).ConclusionsDespite recent treatment advances, unmet needs for psoriasis patients remain. Cal/BD foam offers improved efficacy in baseline matched psoriasis patients compared to apremilast, methotrexate or acitretin, and comparable efficacy to FAE.

Project description:IntroductionPsoriasis is a chronic, inflammatory disease, which ranges in severity from mild to severe. Although topical therapies are frequently used to treat mild disease, they are not routinely used to treat patients with moderate-to-severe disease who have a larger proportion of their body surface area (BSA) affected (≥ 5% BSA). Based on well-controlled trials in adults with mild-to-severe disease, fixed-dose combination calcipotriol 50 μg/g + betamethasone dipropionate 0.5 mg/g (Cal/BD) cutaneous foam has been approved (Enstilar®, LEO Pharma) in the USA and EU for the treatment of psoriasis vulgaris for up to 4 weeks in adults. In this post-hoc subgroup analysis, we used pooled data from phase II/III trials to investigate the efficacy and safety of Cal/BD cutaneous foam in patients with moderate-to-severe psoriasis.MethodsPatients included in this analysis had psoriasis affecting 5-15% BSA and a physician's global assessment (PGA) ≥ 3. Endpoints included: treatment success by PGA (rating: clear/almost clear), patient's global assessment (PaGA) at week 4 (rating: clear/very mild) and safety.ResultsA total of 340 patients in the three randomized trials met the BSA/PGA inclusion criteria, of whom 254 were treated with Cal/BD foam and 86 with vehicle foam. Treatment success by PGA and PaGA at week 4 was achieved in 143 (58.1%) and 138 (56.1%) patients receiving Cal/BD foam, respectively, versus three (3.6%) and 14 (16.7%) patients receiving vehicle foam. Sixty-six adverse events (AEs) occurred in 47 (18.5%) patients receiving Cal/BD foam and 11 AEs occurred in 11 (12.8%) patients receiving vehicle foam. Three severe AEs and 15 non-serious treatment-related AEs occurred in patients receiving Cal/BD foam.ConclusionThe results from three clinical trials analyzed together show that topical Cal/BD foam is well tolerated and efficacious for treating patients with moderate-to-severe disease. Data support Cal/BD foam as a potential topical therapy for moderate-to-severe psoriasis.Trial registrationsClinicalTrials.gov registration numbers: NCT01866163, NCT02132936, NCT01536886.
