BACKGROUND: For psoriatic patients who need to receive nonlive or live vaccines, evidence-based recommendations are needed regarding whether to pause or continue systemic therapies for psoriasis and/or psoriatic arthritis. OBJECTIVE: To evaluate literature regarding vaccine efficacy and safety and to generate consensus-based recommendations for adults receiving systemic therapies for psoriasis and/or psoriatic arthritis receiving nonlive or live vaccines. METHODS: Using a modified Delphi process, 22 consensus statements were developed by the National Psoriasis Foundation Medical Board and COVID-19 Task Force, and infectious disease experts. RESULTS: Key recommendations include continuing most oral and biologic therapies without modification for patients receiving nonlive vaccines; consider interruption of methotrexate for nonlive vaccines. For patients receiving live vaccines, discontinue most oral and biologic medications before and after administration of live vaccine. Specific recommendations include discontinuing most biologic therapies, except for abatacept, for 2-3 half-lives before live vaccine administration and deferring next dose 2-4 weeks after live vaccination. LIMITATIONS: Studies regarding infection rates after vaccination are lacking. CONCLUSION: Interruption of antipsoriatic oral and biologic therapies is generally not necessary for patients receiving nonlive vaccines. Temporary interruption of oral and biologic therapies before and after administration of live vaccines is recommended in most cases.

OBJECTIVE: Controlling molluscum contagiosum (MC) infections is critical in atopic dermatitis (AD) management. This post hoc analysis assessed the efficacy and safety of berdazimer gel, 10.3% (topical, antiviral, nitric oxide-releasing medication) versus vehicle in MC patients with or without AD. METHODS: Three Phase 3, multicenter, randomized, double-blind, vehicle-controlled, parallel-group trials (B-SIMPLE[berdazimer sodium in molluscum patients with lesions]1, -2, -4) enrolled patients 6 months and older with 3-70 mollusca. Berdazimer or vehicle was applied once daily to all MC lesions for 12 weeks. Data from three Phase 3 studies were integrated for subgroup efficacy and safety assessments using several weighted meta-analysis approaches. Patients with concurrent AD or a history of AD/eczema were categorized as AD+ subgroup (AD- when absent). Primary efficacy endpoint: complete lesion clearance at Week 12. Safety endpoints included adverse events (AEs) through Week 24 and local skin reactions through Week 12. RESULTS: Of 1598 enrolled patients, 209 (13.1%) were AD+. Baseline mean lesion counts were greater in AD+ (26.4) than AD- (19.3). Complete clearance rates were higher at Week 12 for berdazimer compared with vehicle in AD+ (n = 209; 35.0% vs. 27.4%; odds ratio [OR], 1.3; 95% CI, 0.7-2.5) and AD- (n = 1389; 29.1% vs. 18.9%; OR 1.8; 95% CI 1.4-2.4) subgroups. AEs in AD+ were application-site pain (21.6% with berdazimer vs. 11.9% with vehicle), dermatitis (12.8% vs. 2.4%), and erythema (9.6% vs. 7.1%). CONCLUSIONS: Berdazimer gel showed favorable efficacy regardless of AD status. Berdazimer-induced erythema may be indistinguishable from AD symptoms or with inflammatory response upon resolution of molluscum.

BACKGROUND: An out-of-office therapeutic agent indicated for molluscum contagiosum is needed. OBJECTIVE: To assess the efficacy and safety of berdazimer gel, 10.3% (a topical, antiviral, nitric oxide-releasing medication) versus vehicle. METHODS: Berdazimer gel, 10.3% or vehicle was applied once daily to all molluscum contagiosum lesions for 12 weeks in patients ≥6 months with 3-70 mollusca. Efficacy assessment: complete lesion clearance and partial clearance at week 12. Safety and tolerability assessment: adverse events through week 24 and local skin reactions through week 12. RESULTS: There were 1598 patients enrolled (n = 917 berdazimer, n = 681 vehicle). Berdazimer was superior to vehicle at week 12 in complete clearance rates, 30.0% versus 19.8% (odds ratio, 1.75; 95% CI, 1.38-2.23, P < .001). Subgroup analyses of primary efficacy showed consistent favorable efficacy for berdazimer across most subgroups, including age, sex, baseline lesion count, and disease duration. Berdazimer provided favorable outcome for partial clearance. Application-site pain (18.7% vs 4.8% in berdazimer vs vehicle) and erythema (11.7% vs 1.3%), mostly mild to moderate, were the most common local skin reactions. LIMITATIONS: Berdazimer sodium in molluscum patients with lesions (B-SIMPLE) trials enrolled only US patients; no efficacy assessments beyond week 12. CONCLUSIONS: Berdazimer gel, 10.3% showed favorable efficacy and safety across subgroups.

Microencapsulation has received extensive attention because of its various applications. Since its inception in the 1940s, this technology has been used across several areas, including the chemical, food, and pharmaceutical industries. Over-the-counter skin products often contain ingredients that readily and unevenly degrade upon contact with the skin. Enclosing these substances within a silica shell can enhance their stability and better regulate their delivery onto and into the skin. Silica microencapsulation uses silica as the matrix material into which ingredients can be embedded to form microcapsules. The FDA recognizes amorphous silica as a safe inorganic excipient and recently approved two new topical therapies for the treatment of rosacea and acne. The first approved formulation uses a novel silica-based controlled vehicle delivery technology to improve the stability of two active ingredients that are normally not able to be used in the same formulation due to potential instability and drug degradation. The formulation contains 3.0% benzoyl peroxide (BPO) and 0.1% tretinoin topical cream to treat acne vulgaris in adults and pediatric patients. The second formulation contains silica microencapsulated 5.0% BPO topical cream to treat inflammatory rosacea lesions in adults. Both formulations use the same amorphous silica sol-gel microencapsulation technology to improve formulation stability and skin compatibility parameters.

Objective: We sought to assess the long-term safety and tolerability of microencapsulated benzoyl peroxide cream, 5% (E-BPO cream, 5%), in subjects with rosacea. Efficacy and tolerability have been previously demonstrated in two 12-week, randomized, double-blind, vehicle-controlled Phase III trials. Methods: In this open-label extension study (NCT03564145; clinicaltrials.gov), all subjects from the initial placebo-controlled Phase III trials could receive E-BPO cream, 5%, for up to an additional 40 weeks, up to a total of 52 weeks of E-BPO cream, 5%, exposure. If a subject was assessed at study visits as "clear" or "almost clear" using the 5-point Investigator Global Assessment (IGA) scale (IGA 0 or 1), E-BPO cream, 5%, was not dispensed. If a subject was assessed as "mild to severe" (IGA 2+), E-BPO cream, 5%, was applied daily until they reached "clear" or "almost clear." Results: The safety and tolerability profile for E-BPO cream, 5%, was similar to that reported in the Phase III studies. Five subjects (0.9%) discontinued study drug due to treatment-related adverse events, and 17 subjects (3.2%) experienced an adverse event considered related to study drug. IGA success after 40 weeks of active treatment was 66.5 percent for subjects continuing from the Phase III vehicle group (n=172) and 67.6 percent for subjects who continued Phase III E-BPO cream, 5% (n=363). The study ended early in accordance with the protocol. Limitations: Safety and tolerability of E-BPO were not compared with those of unencapsulated BPO. Conclusion: E-BPO cream, 5%, showed a favorable safety and tolerability profile during this 40-week, open-label extension study.
RESUMO
Objective: A new formulation of benzoyl peroxide (E-BPO cream, 5%) entraps benzoyl peroxide (BPO) in silica microcapsules. This study assesses the efficacy, safety, and tolerability of E-BPO cream, 5%, in rosacea in two Phase III clinical trials. Methods: In two 12-week, randomized, double-blind, vehicle cream-controlled Phase III trials, 733 subjects at least 18 years old with moderate to severe rosacea were randomized (2:1) to once-daily E-BPO cream, 5%, or vehicle. Results: In Study 1, the proportion of subjects achieving IGA clear/almost clear at Week 12 was 43.5 percent for E-BPO cream, 5%, and 16.1 percent for vehicle. In Study 2, the respective values were 50.1 percent and 25.9 percent. In Study 1, the decrease in lesion count from baseline to Week 12 was -17.4 for E-BPO cream, 5%, versus -9.5 for vehicle. In Study 2, the respective values were -20.3 and -13.3 (all P<0.001). The difference was also significant at Week 2. There were no treatment-related serious adverse events; 1.4 percent of subjects (1.8% E-BPO cream, 5%, 0.4% vehicle) discontinued due to adverse events. Assessed local tolerability was found to be similar among subjects in both E-BPO and vehicle.E-BPO was not compared with unencapsulated BPO. Conclusion: E-BPO is an effective and well tolerated treatment for rosacea. Clinicaltrials.gov Identifiers: NCT03564119, NCT03448939.
RESUMO
Importance: Current topical treatment options for seborrheic dermatitis are limited by efficacy and/or safety. Objective: To assess safety and efficacy of roflumilast foam, 0.3%, in adult patients with seborrheic dermatitis affecting the scalp, face, and/or trunk. Design, Setting, and Participants: This multicenter (24 sites in the US and Canada) phase 2a, parallel group, double-blind, vehicle-controlled clinical trial was conducted between November 12, 2019, and August 21, 2020. Participants were adult (aged ≥18 years) patients with a clinical diagnosis of seborrheic dermatitis for a 3-month or longer duration and Investigator Global Assessment (IGA) score of 3 or greater (at least moderate), affecting 20% or less body surface area, including scalp, face, trunk, and/or intertriginous areas. Data analysis was performed from September to October 2020. Interventions: Once-daily roflumilast foam, 0.3% (n = 154), or vehicle foam (n = 72) for 8 weeks. Main Outcomes and Measures: The main outcome was IGA success, defined as achievement of IGA score of clear or almost clear plus 2-grade improvement from baseline, at week 8. Secondary outcomes included IGA success at weeks 2 and 4; achievement of erythema score of 0 or 1 plus 2-grade improvement from baseline at weeks 2, 4, and 8; achievement of scaling score of 0 or 1 plus 2-grade improvement from baseline at weeks 2, 4, and 8; change in Worst Itch Numeric Rating Scale (WI-NRS) score from baseline; and WI-NRS success, defined as achievement of 4-point or greater WI-NRS score improvement in patients with baseline WI-NRS score of 4 or greater. Safety and tolerability were also assessed. Results: A total of 226 patients (mean [SD] age, 44.9 [16.8] years; 116 men, 110 women) were randomized to roflumilast foam (n = 154) or vehicle foam (n = 72). At week 8, 104 (73.8%) roflumilast-treated patients achieved IGA success compared with 27 (40.9%) in the vehicle group (P < .001). Roflumilast-treated patients had statistically significantly higher rates of IGA success vs vehicle at week 2, the first time point assessed. Mean (SD) reductions (improvements) on the WI-NRS at week 8 were 59.3% (52.5%) vs 36.6% (42.2%) in the roflumilast and vehicle groups, respectively (P < .001). Roflumilast was well tolerated, with the rate of adverse events similar to that of the vehicle foam. Conclusions and Relevance: The results from this phase 2a randomized clinical trial of once-daily roflumilast foam, 0.3%, demonstrated favorable efficacy, safety, and local tolerability in the treatment of erythema, scaling, and itch caused by seborrheic dermatitis, supporting further investigation as a nonsteroidal topical treatment.

Four posters about the novel, fixed-dose calcipotriol and betamethasone dipropionate cream (CAL/BDP cream) based on Poly-Aphron Dispersion (PAD) Technology were presented at the 30th European Academy of Dermatology and Venereology (EADV) Congress 2021 and are summarized here. CAL/BDP cream was compared in two randomized, phase 3 trials to vehicle and active comparator (CAL/BDP gel/topical suspension [TS]) in adults with plaque psoriasis (NCT03802344 and NCT03308799). Pooled data from both trials demonstrated significant greater efficacy in favour of CAL/BDP cream for all efficacy endpoints, including PGA treatment success, mPASI, and mPASI75 compared to CAL/BDP gel/TS. CAL/BDP cream was well tolerated and comparable to CAL/BDP gel/TS with no adverse drug reactions with a frequency >1%. In the NCT03308799 study, CAL/BDP cream demonstrated a substantial improvement in the proportion of participants achieving a minimum 4-point improvement on the peak pruritus numeric rating scale (NRS) score compared with vehicle at Weeks 1, 4 and 8. CAL/BDP cream also improved quality of life (QoL), as assessed through the Dermatology Life Quality Index (DLQI), and the EQ-VAS at Week 8 compared with active comparator. Treatment convenience of CAL/BDP cream, as measured by the Psoriasis Treatment Convenience Scale, was superior to CAL/BDP gel/TS at all studied timepoints, including questions addressing formulation's greasiness and overall treatment satisfaction. Finally, an indirect comparison following the Bucher's method of adjusted indirect comparison and the difference-in-differences method was conducted to compare CAL/BDP cream and CAL/BDP foam, as both therapies have been compared to CAL/BDP gel/TS. Indirect evidence showed that treatment with CAL/BDP cream was associated with a trend for greater QoL improvement than CAL/BDP foam when DLQI improvement was assessed at the recommended treatment duration of 8 weeks for CAL/BDP cream and 4 weeks for CAL/BDP foam. CAL/BDP cream was statistically superior versus CAL/BDP foam in four out of five treatment satisfaction domains.

Importance: Once-daily roflumilast cream, 0.3%, a potent phosphodiesterase 4 inhibitor, demonstrated efficacy and was well tolerated in a phase 2b trial of patients with psoriasis. Objective: To evaluate the efficacy of roflumilast cream, 0.3%, applied once daily for 8 weeks in 2 trials of patients with plaque psoriasis. Design, Setting, and Participants: Two phase 3, randomized, double-blind, controlled, multicenter trials (DERMIS-1 [trial 1; n = 439] and DERMIS-2 [trial 2; n = 442]) were conducted at 40 centers (trial 1) and 39 centers (trial 2) in the US and Canada between December 9, 2019, and November 16, 2020, and between December 9, 2019, and November 23, 2020, respectively. Patients aged 2 years or older with plaque psoriasis involving 2% to 20% of body surface area were enrolled. The dates of final follow-up were November 20, 2020, and November 23, 2020, for trial 1 and trial 2, respectively. Interventions: Patients were randomized 2:1 to receive roflumilast cream, 0.3% (trial 1: n = 286; trial 2: n = 290), or vehicle cream (trial 1: n = 153; trial 2: n = 152) once daily for 8 weeks. Main Outcomes and Measures: The primary efficacy end point was Investigator Global Assessment (IGA) success (clear or almost clear status plus ≥2-grade improvement from baseline [score range, 0-4]) at week 8, analyzed using a Cochran-Mantel-Haenszel test stratified by site, baseline IGA score, and intertriginous involvement. There were 9 secondary outcomes, including intertriginous IGA success, 75% reduction in Psoriasis Area and Severity Index (PASI) score, and Worst Itch Numeric Rating Scale score of 4 or higher at baseline achieving 4-point reduction (WI-NRS success) at week 8 (scale: 0 [no itch] to 10 [worst imaginable itch]; minimum clinically important difference, 4 points). Results: Among 881 participants (mean age, 47.5 years; 320 [36.3%] female), mean IGA scores in trial 1 were 2.9 [SD, 0.52] for roflumilast and 2.9 [SD, 0.45] for vehicle and in trial 2 were 2.9 [SD, 0.48] for roflumilast and 2.9 [SD, 0.47]) for vehicle. Statistically significantly greater percentages of roflumilast-treated patients than vehicle-treated patients had IGA success at week 8 (trial 1: 42.4% vs 6.1%; difference, 39.6% [95% CI, 32.3%-46.9%]; trial 2: 37.5% vs 6.9%; difference, 28.9% [95% CI, 20.8%-36.9%]; P < .001 for both). Of 9 secondary end points, statistically significant differences favoring roflumilast vs vehicle were observed for 8 in trial 1 and 9 in trial 2, including intertriginous IGA success (71.2% vs 13.8%; difference, 66.5% [95% CI, 47.1%-85.8%] and 68.1% vs 18.5%; difference, 51.6% [95% CI, 29.3%-73.8%]; P < .001 for both), 75% reduction in PASI score (41.6% vs 7.6%; difference, 36.1% [95% CI, 28.5%-43.8%] and 39.0% vs 5.3%; difference, 32.4% [95% CI, 24.9%-39.8%]; P < .001 for both), WI-NRS success (67.5% vs 26.8%; difference, 42.6% [95% CI, 31.3%-53.8%] and 69.4% vs 35.6%; difference, 30.2% [95% CI, 18.2%-42.2%]; P < .001 for both). The incidence of treatment-emergent adverse events was 25.2% with roflumilast vs 23.5% with vehicle in trial 1 and 25.9% with roflumilast vs 18.4% with vehicle in trial 2. The incidence of serious adverse events was 0.7% with roflumilast vs 0.7% with vehicle in trial 1 and 0% with roflumilast vs 0.7% with vehicle in trial 2. Conclusions and Relevance: Among patients with chronic plaque psoriasis, treatment with roflumilast cream, 0.3%, compared with vehicle cream resulted in better clinical status at 8 weeks. Further research is needed to assess efficacy compared with other active treatments and to assess longer-term efficacy and safety.

The choice of vehicle is an important consideration in the treatment of acne and rosacea. Agents used to treat these common conditions may be limited by multiple factors, including poor stability during storage, limited residence time in the skin and follicular unit, and high potential for skin irritation. Novel drug delivery systems have been developed to address these problems, including microencapsulation, liposomal encapsulation, and the use of a variety of nanocarriers. New vehicle technologies for acne and rosacea treatments have appeared over the past 20 years and have somewhat improved stability, tolerability, and possibly efficacy. One of the latest vehicle technologies in acne and rosacea to enhance efficacy, stability, and tolerability is microencapsulation of benzoyl peroxide and tretinoin, which resulted in significant efficacy and good tolerability in patients with each of these two diseases. Other new vehicle technologies include a polymeric form of tretinoin and a microsphere product that combines tretinoin plus clindamycin. It is likely that there will be more reports of clinical success as experience with the rapidly evolving delivery technologies increases. This review summarizes drug delivery systems that have been developed with the aim of improving outcomes for patients being treated for either acne or rosacea. It also focuses, where possible, on formulations that have been evaluated in clinical studies.
RESUMO
BACKGROUND: Two identical phase 3 trials (NCT03168321 and NCT03168334) and pooled post hoc analyses have established efficacy and safety of a polymeric tazarotene 0.045% lotion formulation in patients with moderate-to-severe acne. Presented here are post hoc analyses that further examine efficacy and safety of tazarotene 0.045% lotion by age and sex. METHODS: Patients aged ≥ 9 years with moderate-to-severe acne (score 3 or 4 on the Evaluator's Global Severity Score [EGSS]) were equally randomized to once-daily tazarotene 0.045% lotion or vehicle lotion for 12 weeks. Efficacy outcomes included inflammatory/noninflammatory lesion counts and treatment success (proportion of participants achieving ≥ 2-grade reduction from baseline in EGSS and score of 0 [clear] or 1 [almost clear]). Adolescent and adult females (n=1,013) and males (n=529) were subdivided into 3 age groups: 1319, 2029, and ≥30 years. RESULTS: At week 12, large least-squares mean percent reductions in inflammatory and noninflammatory lesions were observed across all 3 tazarotene-treated age groups in males and females (range, -50.2% to -64.8%). Treatment success rates ranged from 23.6% to 38.4%. Across all efficacy assessments, significant differences between tazarotene and vehicle (P<0.05) were generally observed in the younger male and female participants (1319 and 2029). No notable age-related patterns were found for safety outcomes, though tazarotene-treated males of all age groups reported fewer adverse events than females. CONCLUSIONS: Tazarotene 0.045% lotion is efficacious and well tolerated in female and male adolescents and adults with moderate-to-severe acne.

CLINICAL TRIALS ID: NCT02938494 BACKGROUND: In a Phase II study, tazarotene 0.045% lotion was statistically superior to vehicle and comparable to tazarotene 0.1% cream in reducing acne lesions, with fewer treatment-related adverse events (TEAEs) than the cream. OBJECTIVE: We analyzed data from the aforementioned study post-hoc to evaluate the effects of sex on treatment outcomes. METHODS: Participants aged 12 years or older with moderate-to-severe acne were randomized to tazarotene (0.045% lotion or 0.1% cream) or vehicle (lotion or cream) for 12 weeks of double-blind treatment. Outcomes analyzed in male and female subgroups included changes from baseline in inflammatory/noninflammatory lesions and TEAEs. RESULTS: In the intent-to-treat population (94 males and 116 females), reductions in lesion count were greater with tazarotene (lotion or cream) than with vehicle. In participants receiving tazarotene 0.045% lotion, the least-squares mean percent changes from baseline to Week 12 were greater in females than males, but the differences were not statistically significant (inflammatory [-70.3% vs. -56.2%]; noninflammatory [-60.0% vs. -53.2%]). In both females and males, the TEAE incidence was lower with tazarotene 0.045% lotion than 0.1% cream. CONCLUSION: Tazarotene 0.045% lotion substantially reduced acne lesions in both female and male participants. This newest tazarotene formulation might benefit patients who cannot tolerate older formulations or other topical retinoids. Given the relatively small size of this study, however, the results of this post-hoc analysis are intended to be exploratory in nature.
RESUMO
BACKGROUND: The fixed dose combination of calcipotriene and betamethasone dipropionate (CAL/BDP) is a well-established, efficacious, and safe topical treatment of psoriasis. METHOD: A Phase 3, multicenter, randomized, investigator-blind, active, and vehicle-controlled trial enrolling 796 patients with moderate to severe psoriasis according to the Physician Global Assessment (PGA) scale. Products were applied once daily for 8 weeks. RESULTS: The proportion of patients achieving PGA treatment success after 8 weeks was statistically significantly greater for CAL/BDP cream (37.4%) compared to CAL/BDP TS (22.8%, P<0.0001), and vehicle (3.7%, P<0.0001). A similar statistically significant difference in favor of CAL/BDP cream at week 8 was demonstrated for the percentage change in mPASI from baseline and the proportion of patients obtaining mPASI75. Patient reported treatment convenience for CAL/BDP cream was rated superior to CAL/BDP TS. Safety assessments during the trial demonstrated that CAL/BDP cream was well-tolerated with no adverse reactions with a frequency greater than 1%. CONCLUSION: CAL/BDP cream is a novel topical treatment of psoriasis, which in a single product, offers a unique combination of high efficacy combined with favorable safety and excellent treatment convenience. For these reasons, CAL/BDP cream offers a distinctive advantage for the topical treatment of plaque psoriasis. ClinicalTrials.gov: NCT03308799J Drugs Dermatol. 20(4):420-425. doi:10.36849/JDD.5653.

BACKGROUND: Pivotal studies of approved botulinum toxin type A (BoNTA) formulations for treatment of glabellar lines have mostly included treatment-naive participants, and the impact of prior BoNTA treatment on efficacy and safety is not well documented. OBJECTIVE: To evaluate whether prior BoNTA treatment affects efficacy, duration of response, and tolerability for treatment of glabellar lines. METHODS: Adults with moderate or severe glabellar lines treated with DaxibotulinumtoxinA for Injection (DAXI) or placebo from the randomized, double-blind SAKURA 1/2 trials and the open-label SAKURA 3 safety study were analyzed by prior BoNTA treatment status. Efficacy was evaluated using investigator and participant assessments. RESULTS: In this analysis, 609 participants (52.2% BoNTA-experienced) from the SAKURA 1/2 trials and 2,380 (38.0% BoNTA-experienced) from the SAKURA 3 study were evaluated. Proportion of participants with none or mild glabellar lines and duration of response were similar between the BoNTA-naive and BoNTA-experienced cohorts in both the DAXI and placebo groups. The incidence of adverse events was also comparable regardless of prior BoNTA treatment status. CONCLUSION: Efficacy and tolerability were similar with DAXI and placebo regardless of prior BoNTA treatment. Assuming an appropriate washout is observed, future BoNTA trials should enroll both treatment-experienced and treatment-naive participants to reflect clinical practice.

BACKGROUND: ATX-101 (deoxycholic acid) significantly reduced submental fat (SMF) severity in two 24-week Phase 3 studies (REFINE-1 and REFINE-2). OBJECTIVES: The aim of this study was to evaluate the durability of effect and long-term safety of ATX-101. METHODS: REFINE study patients who maintained ≥1-grade improvement on the Clinician-Reported SMF Rating Scale (CR-1 responders) 12 weeks after their last REFINE treatment were eligible for enrollment in this multicenter, double-blind, nontreatment, long-term, follow-up study (NCT02163902). The primary endpoint was CR-1 response at Years 1, 2, and 3. Patient-reported satisfaction, psychological impact, and adverse events were monitored. RESULTS: In total, 224 patients (ATX-101, nâ =â 113; placebo, nâ =â 111) were enrolled. Maintenance of CR-1 response was significantly better in the ATX-101 group than in the placebo group at Year 1 (86.4% vs 56.8%; Pâ <â 0.001), Year 2 (90.6% vs 73.8%; Pâ =â 0.014), and Year 3 (82.4% vs 65.0%; Pâ =â 0.03). Most (74%) ATX-101âtreated patients satisfied at 12 weeks remained satisfied at Year 3. Significant reductions from baseline in psychological impact scores were sustained through Year 3 (Pâ <â 0.001). No new treatment-related adverse events were reported. CONCLUSIONS: Improvements in submental contour achieved with ATX-101 are maintained for 3 years in most patients. No new safety signals emerged.

BACKGROUND: DaxibotulinumtoxinA for Injection (DAXI) is botulinum toxin Type A formulated with a novel peptide excipient. Two pivotal, single-treatment, placebo-controlled trials demonstrated efficacy and safety for moderate or severe glabellar lines. OBJECTIVE: To further evaluate DAXI in a large, open-label, repeat-treatment study. METHODS: Subjects (n = 2,691) were enrolled from the preceding pivotal trials or de novo and received 40U DAXI. Those who received repeat treatments could be retreated when they returned to baseline on the Investigator Global Assessment-Frown Wrinkle Severity (IGA-FWS) and Patient FWS (PFWS) scales at/after 12 weeks and up to 36 weeks after treatment. RESULTS: High (>96%) response rates (none or mild severity) on the IGA-FWS scale were seen after each of the 3 treatments, with peak response between Weeks 2 to 4. At Week 24, ≥32% had a response of none or mild severity. Peak response rates of ≥92% were observed at Weeks 2 to 4 on the PFWS scale. The median duration for return to moderate or severe severity was 24 weeks. The safety profile was favorable and consistent with previous trials. CONCLUSION: DaxibotulinumtoxinA for Injection efficacy was highly consistent across treatment cycles. These results confirm the previously observed efficacy rates and duration of response.

Objective: The study was conducted to determine the efficacy of the botanical combination incorporated in Kamedis Eczema Therapy Cream (the test product) for children with mild to moderate atopic dermatitis. Design: The study was designed as an interventional, multi-center, double-blind, randomized, controlled study. Setting: Children subjects were a sub-population of the 108 combined population of adults and children evenly randomly divided into three treatment groups: test product, vehicle, and comparator. The vehicle used was the identical test product without the botanical combination while the comparator was a leading OTC brand in the US market. All three groups used the same Kamedis body wash followed by one of the three randomized treatment creams for the affected areas. Participants: Thirty-nine (39) children subjects with uncomplicated, stable, mild to moderate atopic dermatitis were recruited and qualified for the study, 24 female and 15 male, ages varying between 3 and 18. Measurements: Investigators assessed the severity of each subject using the Investigator Global Assessment (IGA), affected Body Surface Area (BSA) extent evaluated parameters at each of the visit days 0, 7, 14, and 28. Subjective symptoms of pruritus and insomnia were evaluated by the patient or their legal guardian. The SCORAD and EASI indexes were calculated based on the collected parameters. Results: The test product demonstrated an improvement in all evaluated and calculated clinical parameters over the vehicle at the end of the treatment duration, proving the validation that the test product is much more effective and beneficial than the vehicle. The test product reached 40% of 'clear' IGA subjects out of the enrolled subjects and 60% out of the 'clear' and 'almost clear' IGA subjects comparing to 8% and 38%, respectively, with the vehicle, presenting a clear advantage over the vehicle. The BSA improvement comparison analysis of the test product over the vehicle yielded P value of less than 0.05, which is statistically significant. The SCORAD and EASI indexes also showed an advantage of the test product versus the vehicle at week 4. Conclusion: The study results validate that the botanical combination is the key factor for the efficacy and improvement of the AD symptoms within this population of children.

Psoriasis (PsO) is a common, systemic, chronic inflammatory disease characterized by key clinical symptoms, including itching, pain, and scaling, and is associated with substantial physical, psychosocial, and economic health burdens. Currently, there is no cure for PsO; however, the introduction of biologic therapies has revolutionized the clinical management of patients with PsO by expanding treatment options to include multiple therapies with different mechanisms of action targeting cytokines, including tumor necrosis factor inhibitors (TNFis), interleukin (IL)-17A inhibitors, an IL-12/23 inhibitor, and IL-23 inhibitors. TNFis are historically considered the first-line biologic treatment and the first-generation biologics; however, increased understanding of TNF-α and IL-17 synergistic functions have recently led to evidence that specifically targeting IL-17 may be more likely to improve disease activity than a more general, nonspecific therapy target, such as TNF-α. This review highlights currently available evidence and demonstrates the differences between TNFis and IL-17A inhibitors in patients with PsO with regard to efficacy and safety.
