Abstract
BACKGROUND A three-pronged approach to acne treatment-combining an antibiotic, antibacterial, and retinoid-could provide greater efficacy and tolerability than single or dyad treatments, while potentially improving patient compliance and reducing antibiotic resistance. OBJECTIVES We aimed to evaluate the efficacy and safety of triple-combination, fixed-dose topical clindamycin phosphate 1.2%/benzoyl peroxide (BPO) 3.1%/adapalene 0.15% (IDP-126) gel for the treatment of acne. METHODS In a phase II, double-blind, multicenter, randomized, 12-week study, eligible participants aged ≥ 9 years with moderate-to-severe acne were equally randomized to once-daily IDP-126, vehicle, or one of three component dyad gels: BPO/adapalene; clindamycin phosphate/BPO; or clindamycin phosphate/adapalene. Coprimary endpoints were treatment success at week 12 (participants achieving a ≥ 2-grade reduction from baseline in Evaluator's Global Severity Score and clear/almost clear skin) and least-squares mean absolute changes from baseline in inflammatory and noninflammatory lesion counts to week 12. Treatment-emergent adverse events and cutaneous safety/tolerability were also assessed. RESULTS A total of 741 participants were enrolled. At week 12, 52.5% of participants achieved treatment success with IDP-126 vs vehicle (8.1%) and dyads (range 27.8-30.5%; P ≤ 0.001, all). IDP-126 also provided significantly greater absolute reductions in inflammatory (29.9) and noninflammatory (35.5) lesions compared with vehicle or dyads (range inflammatory, 19.6-26.8; noninflammatory, 21.8-30.0; P < 0.05, all), corresponding to > 70% reductions with IDP-126. IDP-126 was well tolerated, with most treatment-emergent adverse events of mild-to-moderate severity. CONCLUSIONS Once-daily treatment with the novel fixed-dose triple-combination clindamycin phosphate 1.2%/BPO 3.1%/adapalene 0.15% gel demonstrated superior efficacy to vehicle and all three dyad component gels, and was well tolerated over 12 weeks in pediatric, adolescent, and adult participants with moderate-to-severe acne.

Journal of drugs in dermatology : JDD. 2021;(5):567-570
Abstract
Reduction of psoriasis body surface area (BSA) is associated with improved patient quality of life. Post-hoc analyses of the PSO-LONG study compared impact on BSA of proactive management versus reactive management strategies using calcipotriol/betamethasone dipropionate (Cal/BD) foam. Mean BSA values, as well as normalized area under the curves (AUCs) for patient BSA were assessed. Analyses found that after the PSO-LONG study’s four-week open-label lead-in phase, when all patients received once-daily Cal/BD foam, mean BSA was significantly reduced. Thereafter, mean BSA remained at lower levels in patients on proactive management compared to reactive management. This was reflected in AUC BSA, which was consistently lower in the proactive management arm. Treatment-related differences were statistically significant when analyzing the full analysis set (FAS) population, as well as when restricting the analysis to study completers. Additional analyses restricted the dataset to include only observations from psoriasis remission periods, or periods of disease relapse. Treatment-related differences in AUC were statistically significant in observations during remission, but not during relapse. This could be expected given the trial’s design, wherein all patients who relapsed were offered the same rescue therapy with once daily Cal/BD foam. Similarly, for patients who dropped out, there was no treatment-related difference in mean BSA during the two weeks preceding dropout, likely due to the common occurrence of relapse in these patients. This paper found that proactive management, in addition to preventing more relapses as previously shown, also maintained BSA at a lower level during remission than reactive management.

Abstract
BACKGROUND Tazarotene has been extensively studied in clinical trials and is widely used to treat acne vulgaris (acne), with data suggesting that is one of the most potent topical retinoids. Irritation from the cream, foam, and gel formulations has limited its use in clinical practice. OBJECTIVE To assess the efficacy, safety, and tolerability of a unique tazarotene 0.045% lotion formulation based on polymeric emulsion technology in subjects with moderate or severe acne. Methods: A total of 1614 subjects, 9 years and older were randomized to receive tazarotene 0.045% lotion or vehicle in two identical double-blind, randomized, vehicle-controlled 12-week studies evaluating safety and efficacy (inflammatory [papules and pustules] and noninflammatory [comedonal] lesion counts and using Evaluator Global Severity Scores [EGSS]). Treatment success was defined as at least a 2-grade improvement in EGSS and ‘clear’/’almost clear’ and efficacy assessed through reduction in lesion counts. In addition, patients completed a validated Acne-Specific Quality of Life (Acne-QoL) questionnaire. Safety, adverse events (AEs), and cutaneous tolerability were assessed throughout. RESULTS Tazarotene 0.045% lotion demonstrated statistically significant superiority to vehicle in reducing inflammatory and noninflammatory lesion counts at week 12. Mean percent reductions in inflammatory and noninflammatory lesions were 55.5% and 51.4% (Study 1, both P<0.001 versus vehicle [45.7% and 41.5%, respectively]) and 59.5% and 60.0% (Study 2, both P<0.001 versus vehicle [49.0% and 41.6%, respectively]), with tazarotene 0.045% lotion at week 12. Treatment success was achieved by 25.5% (Study 1) and 29.6% (Study 2) of subjects treated with tazarotene 0.045% lotion (both P<0.001 versus vehicle [13.0% and 17.3%, respectively]). Improvements in QoL domain scores were consistently greater with tazarotene. Tazarotene 0.045% lotion was well-tolerated. The most common treatment-related AEs were application site pain (5.3%), dryness (3.6%), and exfoliation (2.1%). CONCLUSION Tazarotene 0.045% lotion provides statistically significant greater efficacy than vehicle in terms of lesion reduction and treatment success, with a highly favorable safety and tolerability profile in moderate-to-severe acne patients.

Abstract
BACKGROUND Surgical site infection (SSI) is the most common problem after surgery. Although several guidelines have indicated the efficacy of antiseptics, such as chlorhexidine-alcohol and povidone-iodine, in reducing SSI rate, the optimal recommendation is still not established. Olanexidine might have higher bactericidal activity than other antiseptic agents. However, no randomised study has evaluated the efficacy and safety of olanexidine over conventional antiseptics. We compared the effect of aqueous olanexidine and aqueous povidone-iodine on the incidence of SSI following clean-contaminated surgery. METHODS This was a multicentre, prospective, randomised, blinded-endpoint superiority trial for surgical skin antisepsis in clean-contaminated gastrointestinal and hepatobiliary pancreatic surgeries in four Japanese hospitals. Patients aged 20 years or older who underwent elective clean-contaminated wound surgery were randomly assigned in a 1:1 replacement ratio using a computer-generated block randomisation. Patients were randomly assigned to surgical skin antisepsis with an aqueous formulation of 1·5% olanexidine or surgical skin antisepsis with an aqueous formulation of 10% povidone-iodine before surgery. We used olanexidine in a ready-to-use applicator, and povidone-iodine was administered by a brush or by compression using pliers. Both antiseptics were applied from the papilla with a cranial limit and to the upper thigh with a caudal limit. The antiseptics were allowed to dry for 3 min, and then surgery started. Participants, some investigators, and data analysts were masked to treatment allocation. Participant enrolment was done by non-masked investigators. The primary outcome was 30-day SSI assessed in the intention-to-treat population. The surgical wound site of each participant was observed daily. After discharge, participants underwent at least one outpatient visit within 30 days after surgery. This trial is registered with University hospital Medical Information Network, 000031560. FINDINGS Between June 10, 2018, and April 18, 2019, 883 patients were assessed for eligibility. 587 patients were eligible and 294 received olanexidine and 293 received aqueous povidone-iodine before surgery. 30-day SSI occurred in 19 (7%) patients in the olanexidine group and 39 patients (13%) patients in the povidone-iodine group (adjusted risk difference -0·069; 90% CI -0·109 to -0·029; adjusted risk ratio [RR] 0·48, 90% CI 0·30 to 0·74; p=0·002). Five patients (2%) in the olanexidine group and five (2%) in the povidone-iodine group developed adverse skin reactions (adjusted RR 0·99, 95% CI 0·29 to 3·40; p=1·00). INTERPRETATION Olanexidine significantly reduced the occurrence of overall SSI and superficial incisional SSI compared with aqueous povidone-iodine in clean-contaminated surgery. Our results indicate that olanexidine might have a role to prevent SSI in patients who undergo clean-contaminated surgeries. FUNDING Keio University and Ohyama Health Foundation.

Abstract
BACKGROUND The product of the Physician Global Assessment and body surface area (PGA×BSA) is simpler to use than the Psoriasis Area and Severity Index (PASI), which lacks sensitivity in patients with mild psoriasis. OBJECTIVE To compare the PGA×BSA versus the modified PASI (mPASI) for assessing disease severity and therapeutic response to calcipotriol/betamethasone dipropionate (Cal/BD) foam. METHODS This post hoc analysis evaluated the efficacy of Cal/BD foam in mild, moderate, and severe psoriasis, as assessed by the PGA×BSA and mPASI, using data from 3 randomized controlled trials (NCT01536886, NCT01866163, NCT02132936). Spearman correlation and Bland-Altman plots were used to compare the PGA×BSA with the mPASI. RESULTS Proportions of patients receiving Cal/BD foam achieving 75% response for PGA×BSA and mPASI at weeks 1, 2, and 4 were similar and significantly greater than with vehicle (P ≤ .002 at all timepoints); at week 4, mean improvements were 51.0% and 50.7%, respectively. Spearman correlations for mild, moderate, and severe psoriasis were moderate to high between PGA×BSA and mPASI at baseline (r = .51, .72, and .86, respectively; n = 126, 465, and 58, respectively) and high at week 4 (r = .80, .81, and .89, respectively; n = 121, 452, and 58, respectively) (P < .001). LIMITATIONS Pooled data from different trials were not prespecified for post hoc analysis. Interrater reliability was not assessed. CONCLUSION Pooled data analysis showed that the PGA×BSA and mPASI correlation was higher with increasing psoriasis severity.

Dermatology (Basel, Switzerland). 2019;(6):463-470
Abstract
INTRODUCTION Acne is a common skin disease with important psychosocial impact. Often inadequate compliance affects the efficacy of the therapy. Because of emerging use of mobile and electronic health technology, the recent literature evaluated the helpfulness of the tools in medication adherence. The first goal of our study was to evaluate the adherence to therapy with topical adapalene 0.3%/benzoyl peroxide (A-BPO) 2.5% in different groups of patients who received explicative information supported by different strategies. The second goal was to evaluate the patient's quality of life and skin parameters. MATERIALS AND METHODS We enrolled 126 subjects with mild to severe acne vulgaris. They were randomized into 3 groups of 42 patients each and applied daily topical A-BPO (0.3%, 2.5%) for 12 weeks. The first group (G1) was trained on the gel application by an explicative leaflet. The second group (G2) received the same instructions as group 1 and a daily SMS to remind them of the application of the product. The third group (G3) only received standard instructions. Evaluations were performed at the beginning of treatment (T0) and after 12 weeks (T1): assessment of acne severity using the Investigator's Global Assessment (IGA) Scale for Acne Severity, quality of life by the Cardiff Acne Disability Index (CADI) and the Patient-Doctor Relationship Depth-of-Relationship Scale (PDRDS), skin pH, grade of hydration and adherence to treatment with a 7-day recall calendar were also measured. RESULTS After 12 weeks of therapy, we observed a reduction in IGA in all groups confirming the clinical efficacy of the product. In the multiple comparison analysis of IGA score reduction, a significant difference was found in G2 versus G1 and G2 versus G3, while the G1 versus G3 comparison was not statistically significant. However, the leaflet group (G1) showed better results compared to the no-leaflet group (G3). Supporting these data, we observed that adherence days correlated positively with the improvement of the single parameters. Moreover, we observed that SMS and leaflet groups had a greater improvement in quality of life evaluated by CADI and PDRDS scores. CONCLUSIONS According to our data, this experimental setup based on text message service and leaflet service is inexpensive and easy to use. Physicians could consider using these items in their practice to enhance patient adherence and satisfaction as well as treatment outcome.

Cutaneous and ocular toxicology. 2019;(1):48-54
Abstract
BACKGROUND Topical drugs for mild to moderate acne include adapalene (ADA) and benzoyl peroxide(BPO). Supramolecular salicylic acid (SSA), a modified SA preparation, is considered as a new effective therapeutic scheme. OBJECTIVES To compare the safety and efficacy of 2% supramolecular SA (2% SSA) with 0.01% adapalene plus 5% benzoyl peroxide (5%BPO +0.1%ADA) for treatment of facial acne. MATERIALS AND METHODS This was an open-label, split face, randomized and single-centre clinical trial. Subjects with mild to moderate acne were enrolled. Two percent SSA cream were randomly applied on one side of the face while 5%BPO +0.1%ADA gel was applied on the opposite side for 28 days. The numbers of acne lesions, along with side effects of the targeted area were evaluated by the investigators at day 0, day 14, and day 28. Skin water content, TEWL and skin lightening indexes were measured at the same time. RESULTS A total of 31 of acne patients completed the trial. Dates showed that 2% SSA had similar effects to 5%BPO +0.1%ADA in reducing papules/pustules (47.9% vs. 49.8%), non-inflammatory lesions (43.1% vs. 42.7%) and total lesions (44.1% vs. 45.6%; all p > 0.05) at day 28. The skin barrier (skin hydration value and TEWL value), skin brightness (L* value) and erythema (a* values) indicators showed no statistical differences in the left and right sides of the face (p > 0.05). CONCLUSION This study demonstrated that 2% SSA has a similar efficacy with 5%BPO +0.1%ADA in mild to moderate acne treatment. This might be a useful pilot study that could be used to support further larger clinical trials.

Archives of dermatological research. 2019;(8):629-636
Abstract
Alopecia areata is a chronic relapsing autoimmune inflammatory hair disorder with no novel therapy. The objectives of this study are to compare the efficacy of topical calcipotriol vs narrow band ultraviolet B phototherapy (NB-UVB) in the treatment of alopecia areata and its correlation with serum vitamin D3 levels. A randomized-controlled trial has been conducted on 60 patients with scalp alopecia areata randomized into four groups; topical calcipotriol, NB-UVB, both and placebo. All patients were evaluated by assessment of severity of alopecia areata by severity of alopecia tool (SALT) score at baseline and 3 months after treatment and vitamin D3 levels at baseline and after 3 months. SALT score and vitamin D3 levels were significantly improved in all groups except placebo after treatment with (P = 0.026, P = 0.005, P = 0.004, P = 0.140) and (P = 0.028, P = 0.011, P = 0.003, P = 0.725), respectively. Combined therapy showed non-significant improvement in SALT score (P = 0.530, P = 0.643), respectively, and significant improvement in serum vitamin D3 levels than each line alone with (P = 0.021, P = 0.044), respectively. Both topical calcipotriol and NB-UVB are effective therapies in the treatment of AA and associated with improvement of SALT score and vitamin D3 levels.

Dermatology (Basel, Switzerland). 2019;(6):501-508
Abstract
BACKGROUND Several factors have been shown to affect psoriasis pathogenesis, clinical presentation and treatment response. OBJECTIVES The aim of this study was to investigate the potential relationship between patients' baseline characteristics and the efficacy of calcipotriol-betamethasone ointment in patients with mild to moderate plaque psoriasis and to evaluate whether the efficacy is consistent across subgroups. METHOD Using data from the therapeutic equivalence study on patients with plaque psoriasis, post hoc analyses were performed to evaluate the impact of baseline demographic and disease characteristics, habits and comorbidities on the response to treatment with calcipotriol-betamethasone ointment. RESULTS Body mass index (BMI) and obesity were each independently associated (univariate analysis, p < 0.05) with reduction in modified Psoriasis Area and Severity Index (mPASI) and PASI75 (≥75% improvement in mPASI from baseline). Increased body weight is more common in patients with late-onset psoriasis. There was a significant trend for lower response rates with increasing BMI (p = 0.007) and obesity (p = 0.003). The odds of achieving PASI75 is 2.3 times lower for obese compared to normal-weight subjects.If patients with obesity or hypertension were treated with calcipotriol-betamethasone, they were still more likely to achieve PASI75 after 4-week treatment compared to vehicle (p < 0.001). CONCLUSION Increased BMI and obesity present risk factors for reduced treatment effectiveness. Importantly, the efficacy of calcipotriol-betamethasone ointment was consistent in all subgroups.
