Assessing Patients' Satisfaction With Hydrogen Peroxide Topical Solution, 40% for Treatment of Raised Seborrheic Keratoses.

OBJECTIVES: Assess participants’ satisfaction following treatment with a proprietary hydrogen peroxide topical solution 40%, w/w (HP40) for raised seborrheic keratoses (SKs). METHODS: In this Phase 4, open-label study, eligible participants aged 30–75 years had clinically typical raised SKs including 2 target SKs (Physician’s Lesion Assessment™ [PLA] grade of ≥2 [0 = clear; 1 = near clear; 2 = thin (≤1 mm); 3 = thick (>1 mm)]; 5–15 mm diameter) on the face and 1 target SK on the neck or décolletage. SKs received HP40 treatment on day 1. All SKs with PLA grade ≥1 were retreated on days 15 and 29. Endpoints included patients’ satisfaction with their skin’s appearance at day 113, relationships between patients’ satisfaction and lesion PLA grade (evaluated by chi-square test), and patients’ satisfaction with their treatment experience. RESULTS: Forty-one patients (mean [range] age, 62.4 [46–73] years) completed the study. 95% of patients were at least moderately satisfied with their skin’s appearance and 90.2% of target lesions were clear. A statistically significant association was observed between the number of target lesions achieving clearance and patients’ satisfaction with skin appearance level (χ2=22.03; P=0.001). 93% of patients were at least moderately satisfied with their HP40 treatment experience. Eight patients experienced treatment-emergent adverse events (TEAEs), most of which were mild or moderate; 4 experienced TEAEs considered treatment-related. CONCLUSIONS: Most patients with SKs on the face, neck, and décolletage were satisfied or very satisfied with both their skin’s appearance and their treatment experience following HP40 treatment. These results support the use of HP40 for raised SKs. J Drugs Dermatol. 2020;19(12): doi:10.36849/JDD.2020.4974.

Hydrogen Peroxide Topical Solution, 45% for Common Warts: Phase 2 Efficacy and Safety Trial Results.

BACKGROUND: No FDA-approved prescription therapies are available for common warts. OBJECTIVE: We evaluated a proprietary hydrogen peroxide topical solution, 45% (w/w) (HP45) for treatment of common warts. METHODS: In the phase 2 randomized, double-blind, vehicle-controlled WART-203 trial (NCT03278028), eligible patients aged ≥8 years had 1–6 warts (1 target wart) on the trunk or extremities with a Physician’s Wart Assessment™ (PWA) grade ≥2 (range, 0 [clear] to 3 [wart 3–8 mm in diameter or length]). Patients self-administered HP45 or vehicle twice weekly for 8 weeks and were evaluated through 12 weeks posttreatment (week 20). Efficacy assessments included mean change in target wart PWA grade from baseline at week 8 (primary endpoint) and proportions of patients with target wart clearance. Safety assessments included treatment-emergent adverse events (TEAEs) and local skin reactions (LSRs). RESULTS: A total of 157 patients completed 8 weeks of treatment (HP45, n=79; vehicle, n=78); 151 patients completed the 20-week posttreatment evaluation (HP45, n=75; vehicle, n=76). A significantly greater reduction in mean target wart PWA grade from baseline at week 8 was achieved with HP45 (−0.87) vs vehicle (−0.17; P<0.0001) and maintained at week 20 (−1.00 vs −0.39; P=0.0004). The proportion of patients with target wart clearance at week 8 was significantly greater with HP45 (25.3%) vs vehicle (2.6%; P<0.0001) and remained significantly greater at week 20 (37.3% vs 11.8%; P=0.0002). Forty-seven patients reported 76 TEAEs; most were mild or moderate in severity. Most LSRs were mild and resolved by week 20. In pediatric patients (HP45, n=13; vehicle, n=6), greater reductions in mean target wart PWA grade from baseline were observed with HP45 vs vehicle at weeks 8 (−1.0 vs 0) and 20 (−1.2 vs −0.5). CONCLUSION: These findings support the efficacy and safety of HP45 for the treatment of common warts in patients ≥8 years of age. J Drugs Dermatol. 2020;19(10):969-976. doi:10.36849/JDD.2020.5054.

Pivotal Trial of the Efficacy and Safety of Oxymetazoline Cream 1.0% for the Treatment of Persistent Facial Erythema Associated With Rosacea: Findings from the First REVEAL Trial.

An unmet need exists for a safe, tolerable, effective treatment for moderate to severe persistent facial erythema in patients with rosacea. This pivotal phase 3, multicenter, double-blind study evaluated the efficacy and safety of topical oxymetazoline in patients with facial erythema associated with moderate to severe rosacea. Patients were randomly assigned to treatment with oxymetazoline hydrochloride cream 1.0% or vehicle applied once daily for 29 days, and were followed for 28 days posttreatment. The primary efficacy outcome was having at least a 2-grade decrease from baseline on both the Clinician Erythema Assessment (CEA) and the Subject Self-Assessment for rosacea facial redness (SSA) scales (composite success) at 3, 6, 9, and 12 hours postdose on day 29. Safety assessments included treatment-emergent adverse events (TEAEs) and posttreatment worsening of erythema (composite CEA/SSA increase of 1-grade severity from baseline; rebound effect). A total of 440 patients (mean age, 49.5 years; 78.9% females) were randomized (oxymetazoline, n=222; vehicle, n=218); most had moderate erythema. On day 29, significantly greater proportions of oxymetazoline recipients achieved the primary efficacy outcome at each time point (P less than 0.02) and overall (P less than 0.001) compared with vehicle recipients. The incidence of discontinuation due to TEAEs was low in both groups (oxymetazoline group, 1.8%; vehicle group, 0.5%). The most common TEAEs reported during the entire study period were application-site dermatitis, application-site erythema, and headache in the oxymetazoline group (1.4% each), and headache (0.9%) in the vehicle group. Following cessation of treatment, low proportions of patients experienced rebound effect (oxymetazoline group, 2.2%; vehicle group, 1.1%). Oxymetazoline applied to the face once daily for 29 days was effective, safe, and well tolerated in patients with moderate to severe persistent facial erythema of rosacea.

Efficacy and safety of calcipotriene 0.005% foam for the treatment of plaque-type psoriasis: results of two multicenter, randomized, double-blind, vehicle-controlled, phase III clinical trials.

BACKGROUND: Topical calcipotriene is frequently prescribed for the treatment of plaque-type psoriasis. Calcipotriene is currently available in the US as an ointment, a solution, a cream, and in a fixed-dose combination ointment with betamethasone dipropionate. Calcipotriene 0.005% has recently been formulated as a foam using a novel aqueous-based formulation to provide a new topical treatment option for patients with psoriasis. OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of topical calcipotriene 0.005% foam for the treatment of mild to moderate plaque-type psoriasis. DESIGN: Two identical, randomized, double-blind, vehicle-controlled, 8-week phase III clinical trials. INTERVENTION: Subjects with plaque-type psoriasis affecting 2-20% of the body surface area, with an identifiable target lesion affecting the trunk or extremities, were randomized in a 2:1 ratio to calcipotriene foam (n = 437) or vehicle foam (n = 222). Study medication was applied twice daily for 8 weeks. OUTCOME MEASURES: Treatment success was defined as a score of 0 or 1 (clear or almost clear) on the Investigator's Static Global Assessment (ISGA) psoriasis rating scale and a minimum improvement of ISGA score of at least 2 grades from baseline. Predefined target lesions were assessed for erythema, scaling, and plaque thickness. Primary endpoint was the proportion of subjects in each treatment group who achieved treatment success after 8 weeks, analyzed on an intent-to-treat (ITT) basis. In the primary endpoint analysis, subjects missing 8-week outcomes data were classified as treatment failures regardless of their outcomes at earlier evaluations. As part of the sensitivity analysis, a last-observation-carried-forward (LOCF) approach to impute missing 8-week efficacy outcomes also examined treatment. Secondary endpoints included treatment success as a function of baseline ISGA score (mild or moderate), ISGA score of 0 or 1 (clear or almost clear), and effects of treatment on target lesion. Adverse events (AEs) were recorded throughout the study. RESULTS: In the ITT population of Study 1, treatment success after 8 weeks was achieved by 14% of subjects in the calcipotriene foam group versus 7% of subjects in the vehicle foam group (p = 0.058). In the LOCF analysis, treatment success was achieved by more subjects with calcipotriene foam than with vehicle foam (15% vs 7%; p = 0.034). In Study 2, treatment success was achieved by more subjects in the calcipotriene foam group for the primary endpoint (27% vs 16%; p = 0.016) and the LOCF analysis (28% vs 16%; p = 0.010). Subjects in the calcipotriene foam group exhibited better response rates than did the vehicle foam group for most of the secondary outcomes. Calcipotriene foam was safe with an overall incidence of AEs similar to those experienced in the vehicle foam group. Application-site reactions were noted in approximately 1-2% of subjects in each group. No AE was reported in more than 2% of subjects in the calcipotriene foam group. Treatment was discontinued because of AEs in approximately 2% of subjects in both groups. CONCLUSIONS: In two identically designed, phase III clinical trials, calcipotriene 0.005% foam was safe and effective for the treatment of mild to moderate plaque-type psoriasis for up to 8 weeks.
