    Purpose: Topical clindamycin, a lincosamide antibiotic, is commonly combined with benzoyl peroxide or a retinoid for acne vulgaris (AV) treatment. While oral and topical clindamycin carry warnings/contraindications regarding gastrointestinal (GI) adverse events (AEs), real-world incidence of GI AEs with topical clindamycin is unknown. This review provides background information and an overview of safety data of topical clindamycin for treating AV.

    Materials and Methods: Available safety data from published literature, previously unpublished worldwide pharmacovigilance data, and two retrospective cohort studies were reviewed.

    Results and Conclusions: According to pharmacovigilance data, the rate of GI adverse drug reactions with topical clindamycin-containing products was 0.000045% (64/141,084,533). Results from two retrospective medical record studies of patients with AV indicated that physicians prescribe topical clindamycin equally to patients with or without inflammatory bowel disease history, and that rates of pseudomembranous colitis in these patients were low. In 8 published pivotal clinical trials of topical clindamycin for AV, GI AEs were reported in 1.4% of participants. Limitations include under/inaccurate reporting of AEs or prescription data and limited generalizability. This review of published case reports, worldwide pharmacovigilance data, retrospective US prescription data, and clinical trials safety data demonstrates that the incidence of colitis in patients exposed to topical clindamycin is extremely low.

    BACKGROUND: Lebrikizumab improved itch, interference of itch on sleep, and quality of life (QoL) in patients with moderate-to-severe atopic dermatitis (AD), in two Phase 3 trials at 16 weeks compared to placebo.

    OBJECTIVES: We assess improvements in itch and sleep interference due to itch and their impact on QoL measurements after treatment.

    METHODS: Data were analyzed from ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967) in patients with moderate-to-severe AD. QoL was evaluated using Dermatology Life Quality Index (DLQI) at Week 16 in patients (>16 years of age) who were itch responders/non-responders (defined as ≥4-point improvement in Pruritus Numeric Rating Scale) or Sleep-Loss Scale responders/non-responders (defined as ≥2-point improvement in itch interference on sleep).

    RESULTS: In ADvocate1 and ADvocate2, significantly greater proportions of itch responders had a clinically meaningful improvement in measures related to QoL (DLQI scores (0/1), ≤5 DLQI total score and ≥4-point DLQI improvement) compared to itch non-responders. In both studies, a significantly greater proportion of Sleep-Loss Scale responders, reported a DLQI score of (0/1), DLQI total score of ≤5 and DLQI improvement of ≥4 points compared to Sleep-Loss Scale non-responders.

    CONCLUSIONS: Improvement in itch and sleep interference due to itch is associated with improvement in the QoL of patients after treatment with lebrikizumab for moderate-to-severe AD.

    UNLABELLED: registration NCT04146363 (ADvocate1) and NCT04178967 (ADvocate2).

    BACKGROUND: Acne-induced hyperpigmentation (AIH) may accompany acne vulgaris (AV) inflammation in all skin phototypes. Trifarotene has shown depigmenting properties in vivo. This study evaluated trifarotene plus skincare because it is increasingly recognized that holistic AV management should include skincare and treatments.

    METHODS: This is a phase IV double-blind, parallel-group study of patients (13-35 years) with moderate AV and AIH treated with trifarotene (N = 60) or vehicle (N = 63) plus skincare regimen (moisturizer, cleanser, and sunscreen) for 24 weeks. Assessments included the AIH overall disease severity (ODS) score, post-AV hyperpigmentation index (PAHPI), exit interviews, photography, and acne assessments. Standard safety assessments were included.

    RESULTS: Trifarotene 50 μg/g cream improved significantly from baseline in ODS score versus vehicle (-1.6 vs. -1.1, P = 0.03) at Week 12, but scores were comparable between groups at Week 24 (primary endpoint). Trifarotene had a better reduction in PAHPI score at Week 24 (-18.9% vs. -11.3% vehicle, P < 0.01). Lesion count reductions were higher with trifarotene at Week 12 versus vehicle (P < 0.001) and at Week 24 (P < 0.05), as were IGA success rates versus vehicle at Weeks 12 (P < 0.05) and 24 (P < 0.05). Patients agreed that the skincare regimen contributed to less irritation, making treatment adherence easier. Photography showed improvements in pigmentation and erythema across all skin types. AEs were more common in the vehicle group versus trifarotene (30.2 vs. 16.7%, respectively).

    CONCLUSIONS: In all skin phototypes, there was more rapid improvement in the ODS and PAHPI scores with trifarotene by Weeks 12 and 24, respectively. The combination of trifarotene and skincare correlated with high patient satisfaction and adherence to the treatment protocol.

    Cancers of the skin are the most commonly occurring cancers in humans. In fair-skinned populations, up to 95% of keratinocyte skin cancers and 70-95% of cutaneous melanomas are caused by ultraviolet radiation and are thus theoretically preventable. Currently, however, there is no comprehensive global advice on practical steps to be taken to reduce the toll of skin cancer. To address this gap, an expert working group comprising clinicians and researchers from Africa, America, Asia, Australia, and Europe, together with learned societies (European Association of Dermato-Oncology, Euromelanoma, Euroskin, European Union of Medical Specialists, and the Melanoma World Society) reviewed the extant evidence and issued the following evidence-based recommendations for photoprotection as a strategy to prevent skin cancer. Fair skinned people, especially children, should minimise their exposure to ultraviolet radiation, and are advised to use protective measures when the UV index is forecast to reach 3 or higher. Protective measures include a combination of seeking shade, physical protection (e.g. clothing, hat, sunglasses), and applying broad-spectrum, SPF 30 + sunscreens to uncovered skin. Intentional exposure to solar ultraviolet radiation for the purpose of sunbathing and tanning is considered an unhealthy behaviour and should be avoided. Similarly, use of solaria and other artificial sources of ultraviolet radiation to encourage tanning should be strongly discouraged, through regulation if necessary. Primary prevention of skin cancer has a positive return on investment. We encourage policymakers to communicate these messages to the general public and promote their wider implementation.

    BACKGROUND: The topical phosphodiesterase 4 inhibitor roflumilast has been studied in several dermatologic conditions.

    OBJECTIVE: Roflumilast foam 0.3% is being investigated as a topical treatment for seborrheic dermatitis (SD).

    METHODS: In this phase 3, double-blinded trial, patients with SD were randomly assigned (2:1 ratio) to once-daily roflumilast foam 0.3% or vehicle foam for 8 weeks. The primary efficacy outcome was Investigator Global Assessment (IGA) Success at week 8, defined as IGA of 0 (Clear) or 1 (Almost Clear) plus ≥2-point improvement from baseline. Safety was also assessed.

    RESULTS: 79.5% of roflumilast-treated and 58.0% of vehicle-treated patients met the primary endpoint (P < .001); statistically significant differences in IGA Success also favored roflumilast at week 2 (roflumilast: 43.0%; vehicle: 25.7%; P < .001) and week 4 (roflumilast: 73.1%; vehicle: 47.1%; P < .001). Roflumilast was well-tolerated with a low rate of treatment-emergent adverse events.

    LIMITATIONS: Study limitations include the 8-week treatment period for this chronic condition.

    CONCLUSIONS: Once-daily roflumilast foam was superior to vehicle in leading to IGA of Clear or Almost Clear plus ≥2-point improvement from baseline at 8 weeks in patients with SD. Longer trials are needed to determine durability and safety of roflumilast foam in SD.

    BACKGROUND: Acne vulgaris commonly affects adults, adolescents, and preadolescents aged 9 years or older.

    OBJECTIVE: The objective of this study was to provide evidence-based recommendations for the management of acne.

    METHODS: A work group conducted a systematic review and applied the Grading of Recommendations, Assessment, Development, and Evaluation approach for assessing the certainty of evidence and formulating and grading recommendations.

    RESULTS: This guideline presents 18 evidence-based recommendations and 5 good practice statements. Strong recommendations are made for benzoyl peroxide, topical retinoids, topical antibiotics, and oral doxycycline. Oral isotretinoin is strongly recommended for acne that is severe, causing psychosocial burden or scarring, or failing standard oral or topical therapy. Conditional recommendations are made for topical clascoterone, salicylic acid, and azelaic acid, as well as for oral minocycline, sarecycline, combined oral contraceptive pills, and spironolactone. Combining topical therapies with multiple mechanisms of action, limiting systemic antibiotic use, combining systemic antibiotics with topical therapies, and adding intralesional corticosteroid injections for larger acne lesions are recommended as good practice statements.

    LIMITATIONS: Analysis is based on the best available evidence at the time of the systematic review.

    CONCLUSIONS: These guidelines provide evidence-based recommendations for the management of acne vulgaris.

    Objectives: Clascoterone cream 1% is approved for the treatment of acne vulgaris in patients aged ≥12 years. Pooled efficacy and safety data stratified by age and sex from two randomized, double-blind, vehicle-controlled Phase 3 studies (CB-03-01/25 and CB-03-01/26) and an open-label long-term extension study (CB-03-01/27) are presented.

    Methods: Patients with moderate-to-severe acne were randomized 1:1 to twice-daily treatment of the face with clascoterone or vehicle for 12 weeks (W); all patients continuing into the open-label extension study applied clascoterone for up to 9 additional months. Efficacy was assessed in the intention-to-treat (ITT) population for proportion of randomized patients achieving an Investigator’s Global Assessment score of 0 or 1 (IGA 0/1) with a ≥2-point reduction from baseline. Safety was assessed from treatment-emergent adverse events (TEAEs) in all treated patients.

    Results: Of 709/712 patients aged ≥12 years originally randomized to clascoterone/vehicle, 63.9%/60.4% were female, and the mean ± standard deviation (SD) age was 19.8 ± 6.1/19.5 ± 6.1 years; there were only 11/13 male patients aged ≥25 years, and no data are shown for this subgroup. Among patients in the ITT population randomized to clascoterone/vehicle, 17.2%/3.9% (12–17 years; P <0.0001), 24.4%/9.8% (≥18 years; P <0.0001), and 31.5%/10.8% (females ≥25 years; P = 0.002) achieved IGA 0/1 by W12; 45.6%, 54.0%, and 44.4% of extension study patients aged 12–17, ≥18, and females ≥25 years, respectively, achieved IGA 0/1 after 12 months applying clascoterone. Frequency of TEAEs through W12 in clascoterone/vehicle-treated patients was 10.8%/14.2%, 11.5%/11.6%, and 9.6%/12.9% for ages 12–17, ≥18, and females ≥25 years, respectively.

    Conclusions: Clascoterone efficacy and safety were maintained in adolescent and adult patients, including female patients aged ≥25 years.

    Objectives: Clascoterone cream 1% is approved for the treatment of acne vulgaris in patients aged ≥12 years. Efficacy data from an open-label extension study are presented.

    Methods: The open-label, multicenter extension study (CB-03-01/27) enrolled male and female patients aged ≥9 years who completed one of the 12-week Phase 3 trials (CB-03-01/25 and CB-03-01/26) in patients with moderate-to-severe acne vulgaris. All patients applied 1% clascoterone cream twice daily to the face for 9 months; in the extension study, patients with truncal acne could also treat affected areas of the shoulders, chest, and/or back. Total time on clascoterone was up to 12 months for patients originally randomized to clascoterone in the Phase 3 trials. A 5-point Investigator’s Global Assessment (IGA; 0, clear; 4, severe) was performed at extension Days 29, 85, 183, and 274; clascoterone treatment could be discontinued if IGA was 0 or 1 (IGA 0/1) and reinstated if/when acne worsened. Efficacy was analyzed in the intention-to-treat (ITT) population.

    Results: The ITT population included 609 patients, of whom 251 patients were treated for truncal acne. At baseline/Day 29/85/183/274, the proportion of ITT patients achieving facial IGA 0/1 was 9.9%/8.5%/10.1%/17.3%/29.8% and the proportion of ITT patients achieving truncal IGA 0/1 was 4.8%/17.1%/20.7%/25.9%/31.5%. In the ITT population, 539/417/304/123 patients used clascoterone for a total of 3/6/9/12 months. By total time on clascoterone, 13.1%/18.9%/39.2%/56.1% of ITT patients achieved facial IGA 0/1 and 13.6%/37.6%/43.4%/59.2% of ITT patients achieved truncal IGA 0/1 after 3/6/9/12 months on clascoterone treatment.

    Conclusions: Clascoterone cream 1% maintained a favorable efficacy profile for up to 12 months in patients aged ≥9 years with acne vulgaris.

    Objectives: Hidradenitis suppurativa (HS) has one of the greatest impacts on quality of life (QoL) of any dermatological disease. This study explored the patient- and physician-reported burden of HS with and without draining tunnels (dT).

    Methods: This study used real-world data collected (November 2020–April 2021) from physician surveys, patient surveys, and medical records as part of the Adelphi HS Disease Specific Programme (DSP™). Validated patient-reported outcomes used were the HS QoL (HiSQOL) score, the work productivity and activity impairment questionnaire, and the EQ5D-visual analog scale (EQ5D-VAS). Results are presented descriptively. Patients with missing values for a variable were removed from all analyses involving that variable.

    Results: Of 580 moderate-to-severe HS patients included in this study, 46% (n=264) had dT. For patients with and without dT, mean age of 38.9 and 33.3 years, and 55.3% and 57.6% were female, respectively. From physician-reported data, patients with dT were more likely to experience a great impact on their lives than patients without dT (51.1% vs. 31.3%). Physicians agreed (agreement of 7–10 on a 1–10 scale) that patients with dT were more likely to experience a negative impact on their mental health (66.3% vs. 48.7%) and sexual function (65.5% vs. 50.3%). Patients with dT reported higher ratings on a pain scale from 7–10 (10 indicating worst pain, 28.9% vs. 11.0%), and were more likely to experience worse mood, reduced ability to work, negative feelings about the futures, and a deteriorated financial situation. Overall, patients with dT reported worse QoL (HiSQOL, 22.3 vs. 16.2), greater work impairment (34.0% vs. 25.9%), and worse general health (EQ5D-VAS, 62.9 vs. 72.0).

    Conclusions: In this group, patients with dT experienced a more substantial disease burden than patients without dT; this provides insight into the impact of dT and highlights the need for effective treatment strategies.

    The 2022 mpox outbreak affected 84,318 individuals in 110 countries. Mpox is transmitted by multiple modalities, including direct contact, respiratory droplets, and fomites among others. Identifying skin lesions aids prompt diagnosis. Variation in initial skin lesion location is not well understood; it is hypothesized that mode of transmission may determine primary inoculation site and subsequent clinical presentation. This study sourced healthcare provider-reported data from the AAD/ILDS Dermatology COVID-19, Mpox, and Emerging Infections Registry to explore factors related to the location of the first skin lesion in mpox cases. Out 119 mpox cases,115 had primary lesion location data. 97% were male with a median age of 37. Most (83/115, 72%) patients had first skin lesions in the genito-anal area, and 32/115 (27%) had lesions elsewhere or had morbilliform rash. 74% of males had the first lesion in the genito-anal region compared to females (25%, p=0.03). Males in same-sex relationships had ano-genital lesions more often than men in other relationships (77% vs. 44%, p=0.03). The type of mpox exposure was also associated with first lesion location: 83% of patients who contracted mpox from a spouse or other sexual contact had ano-genital lesions as compared to a non-sexual contact (0%, p=<0.01). This analysis characterized factors associated with the first mpox skin lesion location, which can aid healthcare providers in diagnosis and shed light on transmission. This data suggests that type of exposure and mode of transmission may be associated with primary lesion location; patients who contracted mpox from sexual contact were more likely to have ano-genital lesions.

    In 2022, mpox virus spread globally with 99% of cases in non-endemic countries. People living with HIV (PLHIV) are disproportionally affected, often with more severe clinical features and outcomes. The AAD/ILDS Dermatology COVID-19, Monkeypox (mpox), and Emerging Infections registry captured mpox cases from 13 non-endemic countries in a de-identified REDCap registry. We aimed to examine cutaneous symptomatology and outcomes in cases of mpox in PLHIV. Of 119 reported cases, 44 were PLHIV (35%). Cases were 98% male, with a median age of 38 years, located in Europe (57%) and the U.S. (39%). Nearly half of PLHIV reported skin lesions as their initial sign (45%), and 43 (98%) reported skin lesions during illness. The primary initial lesion locations were peri-anal (34%) and genito-inguinal (34%). Co-infection with other sexually transmissible infections (STI) was more common in PLHIV, 57% vs. 38% in all-registry cases (p<0.01). The most common co-infections were gonorrhea, syphilis, and chlamydia. Time to resolution was 17 days, 3 days shorter than all-registry cases, which may be due to higher use of Tecovirimat in PLHIV (36% vs. 25% in all-registry cases; p<0.01). There were no differences in the frequency of hospitalization or scarring. One death was reported. Overall, cutaneous lesion count was similar in PLHIV and all-registry cases. Lesion location was more frequently reported in the peri-anal and genito-inguinal regions. Sample size was insufficient to detect differences in length of infection, hospitalization, or scarring in PLHIV. Co-infections were more common in PLHIV, highlighting a need for co-testing for STIs during mpox evaluation.

    Background: Understanding of AV impact on patient Health-related quality of life (HRQoL) is still evolving.

    Objective: The key objective of this analysis was to evaluate patientperceived impact of AV on emotional/social functioning and ADL through a novel Expert Panel Questionnaire (EPQ), among AV patients administered sarecycline, an oral narrow-spectrum, tetracycline-derived antibiotic, in real-world community practices across the US.

    Methods: A single-arm, prospective cohort study (PROSES) was conducted with moderate-to-severe non-nodular AV patients aged 9 years or older who were prescribed sarecycline. Primary endpoint included 11-item EPQ responses (completed by patients (>12years) and caregivers (for patients 9-11 yrs) at Week 12 and corresponding change from baseline (CFB)). All items were scored on a five-point adjectival response scale (score=0/1 (never/rarely, not at all/slightly/a little), score=2 (some of the time, somewhat), and score=3/4 (most of the time/all of the time, moderately/ extremely, quite a bit/very much). The EPQs related to AV impact on emotional functioning (EPQ 1-4), social functioning (EPQ 5-7), and ADL (EPQ 8-11) were formulated based on dermatology expert panel consensus using modified Delphi method. CFB in proportion of patients reporting score=0/1 (no/least impact) for EPQ items at Week-12 were analyzed.

    Results: A total of 253 AV patients completed the study (adults: 60.08%; pediatric: 39.92%; female: 66.40%). CFB in patients reporting score=0/1 (no/least impact) for each EPQ item increased statistically significantly (p<0.0001) except for EPQ10. In emotional functioning domain, CFB=31.62 percent for EPQ1 on patients' mood/anger; CFB= 28.85 percent, 20.95 percent, 38.74 percent respectively for EPQ2, EPQ3, EPQ4 on hopelessness/worries about skin. In social functioning domain, CFB=23.72 percent for EPQ5 on patients' social media/selfie activity, CFB=22.93 percent for EPQ6 on impact on real-life plans, and CFB=21.34 percent for EPQ7 on efforts to hide AV. In ADL domain, CFB=15.02 percent for EPQ8 on picked-on/judged due to AV, CFB=13.83 percent for EPQ9 on ability to reach future goals, and CFB=0.99 percent for EPQ10 on parent understanding of AV concerns (for patients<18yrs), and CFB=18.18 percent for EPQ11 on sleep impact.

    Conclusion: Patients reporting no/least AV burden in emotional functioning, social functioning, and ADL significantly increased in patients with moderate-to-severe AV who were administered sarecycline for 12 weeks.

    Background: Skin exposure to ultraviolet radiation (UVR) causes DNA damage, which can lead to mutagenesis, carcinogenesis, cellular death, and photoaging. Signs of photoaging include wrinkling, erythema, skin laxity, uneven skin texture, and hyperpigmentation. Photolyase is an exogenous DNA repair enzyme that can restore DNA integrity when applied topically to human skin. Antioxidants also play a key role in reducing UVR-associated molecular damage.

    Objective: To assess the efficacy of a mineral-based sunscreen containing 10.7% zinc oxide (SPF50) with the active ingredients photolyase, antioxidants (Vitamin E and Peptide Q10), and peptides in both protecting against and repairing visible signs of photoaging.

    Methods: In an open-label, single-center, 12-week study, patients aged 35-65 years and Fitzpatrick Skin Types II-IV applied the sunscreen daily for 84 days. VISIA photography was performed at baseline as well as 6- and 12-week follow-ups. At each visit, the investigator and subject evaluated clinical photoaging parameters including overall photodamage, fine lines/wrinkles, coarse lines/ wrinkles, skin tone evenness, tactile roughness, and radiance.

    Results: The Investigator Global Aesthetic Improvement Scale (IGAIS) found that 63 percent of patients showed improvement at Week 6 and 81 percent at Week 12. The Subject Global Aesthetic Improvement Scale (SGAIS) showed 58% percent and 62.5 percent of patients reported the appearance of their skin was improved at Week 6 and 12, respectively. Overall, there was a statistically significant improvement in skin radiance as well as improvement in overall facial aesthetics reported by both investigators and subjects.

    Conclusion: A mineral-based SPF50 sunscreen containing photolyase, antioxidants, and peptides is effective at repairing some clinical signs of photoaging.

    Background: Roflumilast cream is a potent phosphodiesterase 4 inhibitor recently approved in the United States for treatment of plaque psoriasis with no limitations on duration of use. An open-label trial was conducted to evaluate long-term safety (52 weeks) of once-daily roflumilast cream (NCT03764475). This abstract presents data on durability of response as measured by the percentage of patients with an Investigator Global Assessment (IGA) score of Clear or Almost Clear, percentage improvement in Psoriasis Area Severity Index (PASI) score, and reduction in body surface area (BSA) affected.

    Methods: Patients who completed a parent, Phase 2b, 12-week randomized controlled trial could continue on open-label roflumilast cream 0.3% (Cohort-1, n=230), and patients naïve to roflumilast were also enrolled (Cohort-2, n=102). All psoriasis lesions (except scalp) were treated, including face and intertriginous areas for up to 52 weeks. If affected, palms and soles were treated, but not evaluated towards any efficacy assessments. Median duration of response was determined using the Kaplan-Meier method.

    Results: With cumulative treatment up to 64 weeks in Cohort-1 and 52 weeks in Cohort-2, long-term safety and tolerability were consistent with the 12-week, Phase 2b study. Overall, 73.5 percent of patients completed the study; 3.9 percent discontinued due to adverse events (AE) and 0.9 percent discontinued due to lack of efficacy. Treatment-related AEs were reported in 2.7 percent patients; none were deemed serious. Investigator tolerability assessments at each visit demonstrated 99 percent of patients rated “no evidence of irritation.” At Week 52, IGA Success (demonstrating Clear/Almost Clear plus 2-grade improvement from baseline) was achieved by 34.8 percent of patients in Cohort-1 and 39.5 percent in Cohort-2. Of patients in Cohort-2, 40 percent of patients achieved IGA success at Week 12. IGA Clear/Almost Clear was achieved by 46.8 percent of patients across both cohorts at Week 12 and consistent through Week 52 (44.8%). Similarly, a 60.5 percent mean PASI improvement and 60.1 percent mean BSA improvement from baseline were observed at Week 12 and consistent through Week 52 (59.4% and 63.3%, respectively). Of the 185 patients who achieved IGA Clear/Almost Clear during the open-label trial, the median durability of IGA of Clear/ Almost Clear was 10 months (40.1 weeks). Among patients who achieved an IGA of Clear or Almost Clear, 50 percent maintained Clear or Almost Clear status for at least 10 months.

    Conclusion: In this long-term safety study, roflumilast cream was well tolerated with a safety profile consistent with the parent Ph2b trial, and effectively maintained clear/almost clear skin with no tachyphylaxis observed.

    Background: The objective of this analysis was to compare facial IGA and patient's Global assessment (ptGA) of AV at baseline and Weeks 4, 8 and 12, among AV patients administered sarecycline in community practices across the US.

    Methods: A single-arm, prospective cohort study (PROSES) was conducted with moderateto- severe non-nodular AV patients older than 9 years who were prescribed sarecycline in realworld community practices in the US Facial IGA of patient's AV status was reported by the study clinician and ptGA of AV was collected as part of validated ASIS questionnaire; both measures used a five-point adjectival response scale of 0 (clear), 1 (almost-clear), 2 (mild), 3 (moderate), 4 (severe), and collected at baseline and Weeks 4, 8 and 12. Proportion of patients with clear/almost clear AV per IGA and ptGA were analyzed for all study timepoints.

    Results: A total of 253 AV patients completed the study (adults 60.08%; pediatric 39.92%; female: 66.40%; Caucasian/white: 68.38%, African-American: 8.70%; Other-races: 22.92%; moderate AV: 86.56%; severe AV: 13.44%). At baseline, 0 percent and 4.74 percent were clear/ almost clear, per IGA and ptGA respectively. At Week-4, 9.09 percent and 29.18 percent were clear/almost-clear, per IGA and ptGA respectively. At Week-8, 33.99 percent and 41.84 percent were clear/almost-clear, per IGA and ptGA respectively. At Week-12, 58.89 percent and 59.29 percent were clear/almost-clear, per IGA and ptGA respectively. Increase in proportion of patients with clear/almost clear over time, as measured by IGA and ptGA were respectively statistically significant at p<0.0001.

    Conclusion: Within the study cohort administered sarecycline, a narrow-spectrum, tetracyclinederived antibiotic, for 12 weeks, proportion of patients with clear/almost clear facial AV (as measured by clinicians and patients respectively) increased significantly, with almost six out of 10 patients achieving clear/almost clear facial AV at Week 12.

    Background: Tapinarof cream 1% once daily (QD) demonstrated statistically significant efficacy versus vehicle and was well-tolerated in adults with mild to severe plaque psoriasis in PSOARING 1 and 2, two 12-week, Phase 3 trials. In addition, significantly greater improvements in Dermatology Life Quality Index (DLQI) change from baseline at Week 12 were observed with tapinarof versus vehicle.

    Objective: To evaluate correlations between the DLQI and clinical efficacy as assessed by Physician Global Assessment (PGA) and Psoriasis Area and Severity Index (PASI) in PSOARING 1 and 2.

    Methods: Patients in PSOARING 1 and 2 were randomized to tapinarof or vehicle for 12 weeks. The DLQI is a 10-item scale where each item is rated on a 4-point scale from zero (not at all) to three (very much); lower scores indicate higher quality of life (QoL). Efficacy was evaluated using PGA and PASI. Spearman rank correlations evaluated correlations between changes in efficacy and QoL from baseline at Week 12. Analyses used observed cases and were based on the intention-to-treat population.

    Results: 683 tapinarof and 342 vehicle-treated patients from PSOARING 1 and 2 were included in the analyses. At baseline, 79.2 to 83.9 percent of patients had a PGA of 3 (moderate), mean PASI of 8.9-9.1, and mean DLQI of 8.2-8.7 (moderate impact of disease on QoL) in PSOARING 1 and 2. Mean change in DLQI from baseline at Week 12 was -5.0 vs -3.0 (P<0.0001) and -4.7 vs. -1.6 (P<0.0001), with tapinarof versus vehicle in each trial, respectively. The minimal clinically important difference in DLQI of 4 was exceeded at Week 12 in the tapinarof groups. A significantly higher proportion of patients achieved a DLQI of 0 or 1 at Week 12 in the tapinarof groups versus vehicle: 47.4 percent vs 23.3 percent (P<0.0001) and 44.9 percent vs 16.1 percent (P<0.0001) in each trial, respectively; statistical significance in favor of tapinarof was observed as early as Week 4. Improvements in DLQI in the tapinarof groups at Week 12 were statistically correlated with improvements in PGA (0.28 and 0.29, P<0.0001) and PASI (0.28 and 0.40, P<0.0001) in each trial, respectively.

    Conclusion: Tapinarof demonstrated rapid, clinically meaningful, and statistically significant improvements in clinical efficacy and patientreported QoL. A large percentage of tapinaroftreated patients achieved a DLQI of 0 or 1, i.e., no negative effects of disease on QoL. Correlations between improvements in DLQI and clinical efficacy measures suggest that, beyond clinical improvements captured by the PASI and PGA, other important factors such as mental/emotional wellbeing and satisfaction with treatment contribute to the considerable overall improvement in QoL observed in these trials.
