Efficacy, Safety, and Potency of Betamethasone Dipropionate Spray 0.05%: A Treatment for Adults with Mild-to-moderate Plaque Psoriasis.

ABSTRACT: Objective: A spray formulation of betamethasone dipropionate 0.05% (BD spray 0.05%; Sernivo™ [betamethasone dipropionate] Spray 0.05%; Promius Pharma, LLC; Princeton, New Jersey, USA) has been developed for the topical treatment of psoriasis. The objective of these studies was to evaluate the efficacy, safety, and potency of BD spray 0.05%. Design, Setting, Participants, and Measurements: Efficacy and safety were assessed in a randomized, vehicle-controlled, double-blind study in adults with moderate plaque psoriasis (ClinicalTrials.gov identifier: NCT01947491). Additionally, the potential for adrenal suppression and systemic absorption was evaluated in a randomized, open-label study in healthy adults (ClinicalTrials.gov identifier: NCT02070965). Potency was measured in two single-point, randomized, evaluator-blinded studies in healthy adults. Results: BD spray 0.05% was significantly more effective than the vehicle spray in subjects with moderate plaque psoriasis after three, 14, and 28 days of twice-daily treatment. The efficacy of BD spray 0.05% was similar to augmented BD lotion 0.05% after 14 days of treatment. The safety of BD spray 0.05% was similar to that of the vehicle spray over 28 days and to that of augmented BD lotion 0.05% over 14 days. Under maximal use conditions for up to 29 days, the potential for adrenal suppression was no greater with BD spray 0.05% than with a 15-day regimen of augmented BD lotion 0.05%. There was less systemic absorption of BD from BD spray 0.05% than from augmented BD lotion 0.05%. Studies classify BD spray 0.05% as a midpotent corticosteroid. Conclusions: BD spray 0.05%, a midpotent corticosteroid, is an effective and well-tolerated treatment for adults with mild to moderate plaque psoriasis.

Project description:BackgroundAn aerosol foam formulation of fixed combination calcipotriol 50 μg/g (Cal) and betamethasone 0.5 mg/g (as dipropionate; BD) has been developed for psoriasis vulgaris treatment.ObjectiveTo compare Cal/BD aerosol foam pharmacodynamic activity with Cal/BD ointment and with other topical corticosteroids of different potencies by assessing vasoconstrictor potential.MethodsA 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).ResultsThirty-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.ConclusionCal/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:IntroductionThe phase 3 PSO LONG study (NCT02899962) demonstrated superior efficacy of proactive (PM) versus reactive management (RM) using calcipotriene 0.005%/betamethasone dipropionate 0.064% (Cal/BD) foam in adults with psoriasis. Here, we evaluated whether certain baseline parameters had an effect on time to first relapse (TTFR), number of relapses, and assessed interactions between treatment effect.MethodsPSO LONG included an initial 4-week open-label phase (once-daily Cal/BD foam) and a 52-week maintenance phase where patients were randomized to twice-weekly Cal/BD (PM) or vehicle foam (RM), with a 4-week once-daily Cal/BD foam rescue treatment for relapse. Baseline parameters analyzed using a stepwise variable selection procedure included body surface area, modified Psoriasis Area Severity Index (mPASI), Physician Global Assessment (PGA), body mass index, age, sex, Dermatology Life Quality Index, and duration of psoriasis. Continuous variables were divided into groups based on standard criteria.ResultsOverall, the effect of treatment on TTFR did not vary across any baseline parameters. Variables with a statistically significant effect on TTFR were: treatment group (PM vs. RM hazard ratio [HR]: 0.56; p < 0.001); PGA (moderate vs. mild HR: 1.42; severe vs. mild HR: 2.32; overall p = 0.009); mPASI (moderate vs. mild HR: 1.19; severe vs. mild HR: 1.77; overall p = 0.009); and sex (women vs. men HR: 1.26; p = 0.030). Variables with a significant effect on the number of relapses were: treatment group (PM vs. RM, rate ratio [RR] 0.52; p < 0.001); PGA at baseline (moderate vs. mild, RR 1.38; severe vs. mild, RR 2.22; overall p < 0.001); and mPASI (moderate vs. mild, RR 1.25; severe vs. mild, HR 1.70; overall p = 0.002).ConclusionAll patients benefitted from long-term PM versus RM with Cal/BD foam regardless of baseline characteristics, and the benefit of treatment increased with greater disease severity.Trial registrationClinicalTrials.gov identifier, NCT02899962.

Project description:INTRODUCTION:Betamethasone dipropionate (BD) has anti-inflammatory, immunomodulatory, and antiproliferative activity. The aim of the current work was to test the hypothesis that the addition of corticosteroid such as BD and a keratolytic agent such as salicylic acid in nanocarrier based microemulsions formulation would result in enhancement and sustaining of corticosteroid delivery rate leading to better anti-psoriatic activity. Clinical use of BD is restricted to some extent due to its poor permeability across the skin. So to increase its permeation across the skin, microemulsion-based gel formulations were prepared and characterised. MATERIALS AND METHODS:Microemulsions were prepared by aqueous phase titration method, using oleic acid:sefsol (1.5:1), Tween 20, isopropyl alcohol, and distilled water as the oil phase, surfactant, cosurfactant and aqueous phase, respectively. Selected formulations were subjected to physical stability studies and consequently in vitro skin permeation studies. Surface studies of optimized formulation were done by transmission electron microscopy. In vivo anti-inflammatory activity was done by carageenan-induced raw paw edema method. RESULTS:The droplet size of microemulsions ranged from 60 to 190 nm. The optimized formulation exhibited viscosity 28.55 ± 2.03 mP, refractive index 1.409, pH 6.4, and conductivity 10(-4) scm(-1). The optimized microemulsion was converted into hydrogel using carbopol 934, and salicylic acid was incorporated into it. Drug deposition in skin was found to be 29.73 ?g/mg. Assessment of skin permeation was done by histopathology studies which indicated changes in the structure of epidermal membrane of skin. In vivo anti-inflammatory activity indicated 72.11% and 43.96% inhibition of inflammation in case of developed microemulsion gel and marketed gel, respectively. CONCLUSIONS:The developed microemulsion gel containing BD and salicylic acid provided sustained and good anti-inflammatory activity for the treatment of psoriasis.

Project description:IntroductionTo date, there have been no head-to-head clinical studies comparing calcipotriol 0.005% plus betamethasone dipropionate 0.064% (Cal/BD) aerosol foam and halobetasol propionate 0.01% plus tazarotene 0.045% (HP/Taz) lotion for the treatment of plaque psoriasis. However, the efficacy of 4 weeks of Cal/BD foam and 8 weeks of HP/Taz lotion has been compared using a matching-adjusted indirect comparison (MAIC) approach. Here, we compare the efficacy and safety of Cal/BD foam and HP/Taz lotion for up to 52 weeks.MethodsAn unanchored MAIC was conducted using individual patient data from the PSO-LONG Cal/BD foam trial and a 52-week, open-label phase 3 study of HP/Taz lotion (NCT02462083). Key outcomes of interest were Physician's Global Assessment (PGA) success (PGA 0/1 with ≥ 2-point improvement) after 4 or 8 weeks of open-label therapy; the proportion of patients who had body surface area affected (BSA) ≤ 3 after open-label therapy who maintained BSA ≤ 3 to week 52; and adverse events (AEs).ResultsAfter matching, patients were statistically significantly more likely to have PGA success after 4 weeks of Cal/BD foam than after 8 weeks of HP/Taz lotion (84.5% versus 54.4%; p < 0.01). At week 52, 92.5% and 92.4% of patients receiving proactive and reactive Cal/BD foam, respectively, maintained BSA ≤ 3, compared with 49.3% of those treated with HP/Taz lotion (both p < 0.01). Treatment-related AEs, AEs leading to withdrawal, and AEs associated with drug application (dermatitis, application site pain, and pruritus) were significantly rarer with Cal/BD foam than with HP/Taz lotion (all p < 0.01).ConclusionsCal/BD aerosol foam demonstrated significantly greater efficacy than HP/Taz lotion, and had a more favorable safety profile, compared with HP/Taz lotion, for up to 52 weeks. Proactive Cal/BD foam maintenance therapy and reactive use of Cal/BD foam following relapse both had significant advantages over HP/Taz lotion.

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.
