halobetasol and Pain

Topical corticosteroids (TCS) are the mainstay of psoriasis treatment. Safety concerns may limit use. Combination with tazarotene may optimize efficacy and minimize safety and tolerability concerns.. Investigate safety and efficacy of halobetasol propionate 0.01%/tazarotene 0.045% (HP/TAZ) lotion in moderate-to-severe plaque psoriasis.. Two multicenter, randomized, double-blind, vehicle-controlled phase 3 studies (N=418). Subjects randomized (2:1) to HP/TAZ lotion or vehicle once-daily for 8 weeks, 4-week follow-up. Primary efficacy assessment: treatment success (at least a 2-grade improvement from baseline in IGA score and 'clear' or 'almost clear'). Safety and treatment emergent AEs evaluated throughout.. HP/TAZ lotion demonstrated statistically significant superiority over vehicle as early as week 2 (P equals 0.002). By week 8, 40.6% of subjects were treatment successes compared with 9.9% on vehicle (P less than 0.001). A third of subjects remained treatment successes post-treatment. HP/TAZ lotion was also superior in reducing psoriasis signs and symptoms, and Body Surface Area (BSA) involvement. Most frequently reported treatment related AEs were contact dermatitis (6.3%), application site pain (2.6%), and pruritus (2.2%).. No data were collected beyond the 4-week follow-up.. HP/TAZ lotion provides synergistic efficacy that is both rapid and sustained, with good tolerability and safety over 8 weeks use. J Drugs Dermatol. 2018;17(8):855-861.

Previous results from two phase 3 studies demonstrated efficacy and safety of fixed combination halobetasol propionate 0.01%/tazarotene 0.045% (HP/TAZ) lotion in participants with moderate-to-severe plaque psoriasis. This post hoc analysis evaluated sex-specific efficacy and safety of HP/TAZ lotion.. In two randomized, double-blind, phase 3 studies, participants were randomized (2:1) to receive HP/TAZ or vehicle lotion once daily for 8 weeks. Male and female participants were evaluated separately in this pooled analysis. Efficacy assessments included treatment success (at least 2‑grade improvement in Investigator's Global Assessment [IGA] score and score of clear/almost clear), impact on individual signs of psoriasis, and affected Body Surface Area (BSA).. The analysis included 272 males (HP/TAZ, n=175; vehicle, n=97) and 146 females (HP/TAZ, n=101; vehicle, n=45). Significantly more participants achieved overall treatment success at week 8 with HP/TAZ versus vehicle in both male (38.4% vs 9.8%) and female (44.5% vs 9.9%) subgroups (P<0.001, both). Erythema, plaque elevation, and scaling were also reduced by week 8 in both males and females, with significantly more HP/TAZ-treated participants achieving at least 2‑grade improvement in each sign of psoriasis than vehicle-treated participants (P<0.001 each, both groups). Mean reductions in affected BSA were significantly greater with HP/TAZ versus vehicle lotion in both males and females (P≤0.001, both). The most frequent treatment-related adverse events were contact dermatitis, pruritis, and application site pain (each 4.0%) in females and contact dermatitis (7.6%) in males.. HP/TAZ lotion was highly effective and safe in both males and females with moderate-to-severe psoriasis over 8 weeks of once-daily use. J Drugs Dermatol. 2020;19(5): doi:10.36849/JDD.2020.5021.

Background: The use of topical therapy is a key component in the management of almost all psoriasis patients. Topicals are considered first-line therapy for mild disease and are having an increasing role in moderate or severe psoriasis as an integral part of combination therapy. Halobetasol has been shown be effective in moderate or severe localized plaque psoriasis, and tazarotene affords important effects on epidermal hyperproliferation that may be important in more severe disease.\ \ Objective: To investigate the efficacy, safety and tolerability of a once-daily application of a fixed combination halobetasol propionate 0.01% and tazarotene 0.045% (HP/TAZ) lotion in comparison with its vehicle in patients with severe localized plaque psoriasis (as defined by an Investigator Global Assessment (IGA) of 4 and Body Surface Area (BSA) of 3%-12%.\ \ Methods: Post hoc analysis of two multicenter, randomized, double-blind, vehicle-controlled phase 3 studies. Sixty-two patients with severe localized psoriasis (mean BSA 7.4) randomized (2:1) to receive HP/TAZ lotion or vehicle, once-daily for 8 weeks, with a 4-week posttreatment follow-up. Efficacy assessments included treatment success (defined as at least a 2-grade improvement from baseline in the IGA score and a score of ‘clear’ or ‘almost clear’), impact on individual signs of psoriasis (erythema, plaque elevation, and scaling) at the target lesion, BSA, reduction in mean baseline IGAxBSA and achievement of a clinically meaningful response (number of patients who achieved at least a 75% improvement in IGAxBSA). Safety and treatment emergent adverse events (TEAEs) were evaluated throughout.\ \ Results: By week 8, 34.8% of patients were treatment successes compared with 0.0% on vehicle (P=0.004). HP/TAZ lotion was also significantly superior in reducing psoriasis signs and symptoms and improving BSA. At week 8, 47.4% (erythema), 66.4% (plaque elevation), and 65.4% (scaling) subjects achieved at least a 2-grade improvement, compared with 14.0% (P=0.016), 14.8% (P<0.001) and 14.7% (P<0.001) respectively with vehicle. Patients treated with HP/TAZ lotion achieved a 32.8% reduction in baseline mean BSA, compared with a 39.6% increase with vehicle (P=0.013). HP/TAZ lotion achieved a statistically significant superior reduction in mean IGAxBSA compared to vehicle from week 2 (P<0.001 versus vehicle). By week 8, almost half of the patients treated with HP/TAZ lotion achieved a clinically meaningful response (IGAxBSA-75) and
