A Novel Aerosol Foam Formulation of Calcipotriol and Betamethasone Has No Impact on HPA Axis and Calcium Homeostasis in Patients With Extensive Psoriasis Vulgaris.

ABSTRACT: Fixed combination calcipotriol 50 µg/g (Cal; as hydrate) plus betamethasone 0.5 mg/g (as dipropionate; BD) has been formulated in an innovative aerosol foam.To assess systemic safety of Cal/BD aerosol foam.In a multicentre, single-arm, open-label, maximal-use systemic-exposure trial, adult patients with moderate to severe, extensive psoriasis (15%-30% of body surface area, including ?30% of scalp) applied Cal/BD foam once daily. Endpoints were week 4 abnormal adrenocorticotropic hormone (ACTH) challenge test and change in albumin-corrected serum calcium, 24-hour urinary calcium excretion, and urinary calcium-creatinine ratio.35 patients reaching week 4 exhibited normal ACTH responses. At week 4, changes in calcium homeostasis were minor and not clinically relevant; no patients experienced elevations above normal. Disease severity generally improved, and 49% of patients achieved treatment success according to the Physician's Global Assessment of Disease Severity.No clinically relevant HPA axis or calcium homeostasis impact was observed with 4 weeks of once-daily Cal/BD foam in patients with extensive psoriasis vulgaris.

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: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:BackgroundPsoriasis causes worldwide concern because of its high-prevalence, as well as its harmful, and incurable characteristics. Topical therapy is a conventional treatment for psoriasis vulgaris. Chinese medicine (CM) has been commonly used in an integrative way for psoriasis patients for many years. Some CM therapies have shown therapeutic effects for psoriasis vulgaris (PV), including relieving symptoms and improving quality of life, and may reduce the relapse rate. However, explicit evidence has not yet been obtained. The purpose of the present trial is to examine the efficacy and safety of the YXBCM01 granule, a compound Chinese herbal medicine, with a combination of topical therapy for PV patients.Methods/designUsing an add-on design, the trial is to evaluate whether the YXBCM01 granule combined topical therapy is more effective than topical therapy alone for the treatment of PV. The study design is a double-blind, parallel, randomized controlled trial comparing the YXBCM01 granule (5.5 g twice daily) to a placebo. The duration of treatment is 12 weeks. A total of 600 participants will be randomly allocated into two groups, YXBCM01 granule group and placebo group, from 11 general or dermatological hospitals in China. Topical use of calcipotriol betamethasone for the first 4 weeks and calcipotriol ointment for the remaining 8 weeks will be the same standard therapy for the two groups. Patients will be enrolled if they have a clinical diagnosis of PV, a psoriasis area severe index (PASI) of more than 10 or body surface area (BSA) of more than 10%, but PASI of less than 30 and BSA of less than 30%, are aged between 18 and 65-years-old, and provide signed informed consent. The primary outcome, relapse rate, is based on PASI assessed blindly during the treatment. Secondary outcomes include: (i) relapse time interval, (ii) time to onset, (iii) rebound rate, (iv) PASI score, (v) cumulative consumption of medicine, (vi) the dermatology quality life index (DLQI), and (vii) the medical outcomes study (MOS) item short form health survey (SF-36). Analysis will be on intention-to-treat and per-protocol subject analysis principles.DiscussionTo address the effectual remission of the YXBCM01 granule for PV, this trial may provide a novel regimen for PV patients if the granule can decrease relapse rate without more adverse effects.Trial registrationChinese Clinical Trial Registry (http://cwww.chictr.org): ChiCTR-TRC-13003233, registered 26 May 2013.

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.
