Five-year efficacy and safety of tildrakizumab in patients with moderate-to-severe psoriasis who respond at week 28: pooled analyses of two randomized phase III clinical trials (reSURFACE 1 and reSURFACE 2).

BACKGROUND: The phase III reSURFACE 1 and reSURFACE 2 (NCT01722331/NCT01729754) trials of the anti-interleukin-23p19 monoclonal antibody tildrakizumab (TIL) for psoriasis treatment are complete. OBJECTIVES: We present 5-year pooled data from reSURFACE 1 and reSURFACE 2. METHODS: reSURFACE 1 and reSURFACE 2 were double-blind, randomized, controlled studies with optional long-term extensions. Adults with moderate-to-severe chronic plaque psoriasis were randomized 2 : 2 : 1 to TIL 100 mg (TIL 100) or 200 mg (TIL 200) or placebo at weeks 0 and 4, and every 12 weeks thereafter [reSURFACE 2 included an etanercept (ETN) arm]. Efficacy outcomes included proportions of patients achieving absolute and relative improvement from baseline Psoriasis Area and Severity Index (PASI) score through week 244 in TIL responders (≥ 75% improvement from baseline PASI; PASI 75 response) continuously receiving the same dose and ETN partial responders and nonresponders (PASI < 75 response) switched to TIL 200 at week 28. Safety was assessed from adverse events (AEs) in all patients as treated. RESULTS: Efficacy analyses included 329 and 227 week 28 responders to TIL 100 and TIL 200, respectively, and 121 ETN partial responders/nonresponders switched to TIL 200 at week 28. Of TIL 100 or TIL 200 responders and ETN partial responders/nonresponders entering the extensions, 235/302, 176/213 and 85/107, respectively, were evaluated at week 244, and 88·7%, 92·5% and 81·3%, respectively, achieved PASI 75 response. Exposure-adjusted rates of serious AEs were 6·3 and 6·0 patients with events per 100 patient-years of TIL 100 and TIL 200, respectively. CONCLUSIONS: TIL treatment provided sustained disease control over 5 years in week 28 TIL responders and ETN partial responders/nonresponders, with a reassuring safety profile.

A multicentre, randomized, double-masked, parallel group, vehicle-controlled phase IIb study to evaluate the safety and efficacy of 1% and 3% topical minocycline gel in patients with papulopustular rosacea.

BACKGROUND: Papulopustular rosacea is characterized by chronic facial erythema and inflammatory facial lesions. Minocycline has anti-inflammatory properties which may be effective in the treatment of rosacea inflammatory lesions. OBJECTIVES: To assess the safety and efficacy of once-daily topical minocycline gel 1% and 3% in patients with papulopustular rosacea. METHODS: This was a prospective, 12-week, double-blinded study conducted at 26 sites in the United States; 270 patients with papulopustular rosacea and 12-40 inflammatory lesions were randomized to minocycline 1%, minocycline 3% or vehicle. The primary endpoint was the mean change in inflammatory lesions at week 12. Key secondary endpoints included success on an Investigator's Global Assessment (IGA). RESULTS: Baseline mean lesion counts were 24·6, 25·1 and 24·3 in the minocycline 1%, minocycline 3% and vehicle groups, respectively; at week 12, the counts had decreased by 12·6, 13·1 and 7·9, respectively. Minocycline significantly decreased lesions, compared with the vehicle [P = 0·01, 95% confidence interval (CI) 7·9 to 0·9, for minocycline 1%; P = 0·007, 95% CI 8·3 to 1·3, for minocycline 3%]. The proportion of patients achieving IGA success was 39% in the minocycline 1% arm [P = 0·34, odds ratio (OR) 1·396 and OR 95% CI 0·71 to 2·75 vs. vehicle], 46% in the minocycline 3% arm (P = 0·04, OR 2·03 and OR 95% CI 1·04 to 3·95 vs. vehicle) and 31% in the vehicle arm. CONCLUSIONS: Minocycline topical gel appears to be safe and tolerable at concentrations of 1% and 3%, and both concentrations significantly decreased inflammatory lesion counts, with a significantly larger proportion of patients achieving IGA success at week 12 in the minocycline 3% arm. These findings support further evaluation of minocycline gel for treating inflammatory lesions associated with papulopustular rosacea. Linked Comment: Hampton. Br J Dermatol 2020; 183:412-413.

Long-term safety and efficacy of trifarotene 50 µg/g cream, a first-in-class RAR-γ selective topical retinoid, in patients with moderate facial and truncal acne.

BACKGROUND: Treatment for both facial and truncal acne has not sufficiently been studied. OBJECTIVES: To evaluate the long-term safety and efficacy of trifarotene in both facial and truncal acne. METHODS: In a multicentre, open-label, 52-week study, patients with moderate facial and truncal acne received trifarotene 50 µg/g cream (trifarotene). Assessments included local tolerability, safety, investigator and physician's global assessments (IGA, PGA) and quality of life (QOL). A validated QOL questionnaire was completed by the patient at Baseline, Week 12, 26 and 52/ET. RESULTS: Of 453 patients enrolled, 342 (75.5%) completed the study. Trifarotene-related treatment-emergent adverse events (TEAEs) were reported in 12.6% of patients, and none was serious. Most related TEAEs were cutaneous and occurred during the first 3 months. Signs and symptoms of local tolerability were mostly mild or moderate and severe signs, and symptoms were reported for 2.2% to 7.1% of patients for the face and 2.5% to 5.4% for the trunk. Local irritation increased during the first week of treatment on the face and up to Weeks 2 to 4 on the trunk with both decreasing thereafter. At Week 12, IGA and PGA success rates were 26.6% and 38.6%, respectively. Success rates increased to 65.1% and 66.9%, respectively at Week 52. Overall success (both IGA and PGA success in the same patient) was 57.9% at Week 52. At Week 52 visit, 92/171 (53.8%) patients who had completed their assessments had scores from 0 to 1 (i.e. no effect of acne on their QOL) vs. 47/208 (22.6%) patients at Baseline visit. CONCLUSION: In this 52-week study, trifarotene was safe, well tolerated and effective in moderate facial and truncal acne.

Efficacy and safety of the Janus kinase 1 inhibitor PF-04965842 in patients with moderate-to-severe psoriasis: phase II, randomized, double-blind, placebo-controlled study.

BACKGROUND: PF-04965842 is an oral Janus kinase 1 inhibitor being investigated for the treatment of plaque psoriasis. OBJECTIVES: To evaluate the efficacy, safety and tolerability of PF-04965842 in patients with moderate-to-severe plaque psoriasis. METHODS: Patients in this phase II, placebo-controlled study (NCT02201524) were randomized to receive placebo, 200 mg once daily (OD), 400 mg OD or 200 mg twice daily (TD) PF-04965842 for 4 weeks. The primary endpoint was change from baseline in Psoriasis Area Severity Index (PASI) at week 4. Study enrolment was discontinued on 25 June 2015 due to changes in the sponsor's development priorities. RESULTS: Fifty-nine patients were randomized and received at least one dose of PF-04965842 or placebo. The estimated treatment effect (active -placebo PASI change from baseline) and 90% confidence interval at week 4 was -5·1 (-9·2 to -1·0), -5·6 (-9·6 to -1·6) and -10·0 (-14·2 to -5·8) for the 200 mg OD, 400 mg OD and 200 mg TD groups, respectively. At week 4, the proportion of patients achieving PASI 75 was 17% for the placebo and 200 mg OD groups, 50% for the 400 mg OD group and 60% for the 200 mg TD group. There were more abnormal laboratory test results of clinical interest (low neutrophil, reticulocyte and platelet counts) in the 200 mg TD group compared with the OD treatment groups. No serious infections or bleeding events related to neutropenia or thrombocytopenia, respectively, were reported. CONCLUSIONS: These results suggest that treatment with PF-04965842 improves symptoms and is well tolerated in patients with moderate-to-severe psoriasis.

Male skin and ingredients relevant to male skin care.

Male skin care needs are heavily influenced by the need to remove facial hair on a regular basis. Facial skin issues associated with poor hair removal approaches are common and include razor burn and irritation. This paper evaluates current research on shaving technology and how careful ingredient selection can contribute to male skin health. The importance of maintaining hair softness during the shave and restoring facial hydration post-shave is discussed. Data are presented on how post-shave moisturizers containing glycerine and emollients can create an environment for improved barrier function which can be further improved by incorporating specific ingredients such as niacinamide.

Rosacea - global diversity and optimized outcome: proposed international consensus from the Rosacea International Expert Group.

BACKGROUND: The absence of specific histological or serological markers, the gaps in understanding the aetiology and pathophysiology of rosacea, and the broad diversity in its clinical manifestations has made it difficult to reach international consensus on therapy guidelines. OBJECTIVES: The main objective was to highlight the global diversity in current thinking about rosacea pathophysiology, classification and medical features, under particular consideration of the relevance of the findings to optimization of therapy. METHODS: The article presents findings, proposals and conclusions reached by the ROSacea International Expert group (ROSIE), comprising European and US rosacea experts. RESULTS: New findings on pathogenesis provide a rationale for the development of novel therapies. Thus, recent findings suggest a central role of the antimicrobial peptide cathelicidin and its activator kallikrein-5 by eliciting an exacerbated response of the innate immune system. Cathelicidin/kallikrein-5 also provide a rationale for the effect of tetracyclines and azelaic acid against rosacea. Clinically, the ROSIE group emphasized the need for a comprehensive therapy strategy - the triad of rosacea care - that integrates patient education including psychological and social aspects, skin care with dermo-cosmetics as well as drug- and physical therapies. Classification of rosacea into stages or subgroups, with or without progression, remained controversial. However, the ROSIE group proposed that therapy decision making should be in accordance with a treatment algorithm based on the signs and symptoms of rosacea rather than on a prior classification. CONCLUSION: The ROSIE group reviewed rosacea pathophysiology and medical features and the impact on patients and treatment options. The group suggested a rational, evidence-based approach to treatment for the various symptoms of the condition. In daily practice this approach might be more easily handled than prior subtype classification, in particular since patients often may show clinical features of more than one subtype at the same time.

Adapalene-benzoyl peroxide, a unique fixed-dose combination topical gel for the treatment of acne vulgaris: a transatlantic, randomized, double-blind, controlled study in 1670 patients.

BACKGROUND: Combination therapy utilizing agents with complementary mechanisms of action is recommended by acne guidelines to help simultaneously target multiple pathogenic factors. A unique, topical, fixed-dose combination gel with adapalene 0.1% and benzoyl peroxide (BPO) 2.5% has recently been developed for the once-daily treatment of acne. OBJECTIVES: To evaluate the efficacy and safety of adapalene 0.1%-BPO 2.5% fixed-dose combination gel (adapalene-BPO) relative to adapalene 0.1% monotherapy (adapalene), BPO 2.5% monotherapy (BPO), and the gel vehicle (vehicle) in a large population for the treatment of acne vulgaris. METHODS: In total, 1670 subjects were randomized in a double-blind controlled trial to receive adapalene-BPO, adapalene, BPO or vehicle for 12 weeks (1 : 1 : 1 : 1 randomization). Evaluations included success rate (subjects 'clear' or 'almost clear'), percentage change in lesion count from baseline, cutaneous tolerability and adverse events. RESULTS: Adapalene-BPO was significantly more effective than corresponding monotherapies, with significant differences in percentage lesion count change observed as early as 1 week. Cutaneous tolerability profile was similar to adapalene. Adverse events were more frequent with the combination therapy (mainly due to an increase in mild-to-moderate dry skin), occurred early in the study, and were transient. CONCLUSIONS: Adapalene-BPO provides significantly greater and synergistic efficacy and a faster onset of action with an acceptable safety profile in the treatment of acne vulgaris when compared with the corresponding vehicle and the adapalene and BPO monotherapies.

The dermatology dispensing debate.

The in-office dispensing of topical skin care products by dermatologists is a source of frequent debate. Guidelines for proper dispensing have been penned by various medical organizations, yet the controversy continues. With the increasing number of physician-dispensed lines available for sale, combined with mounting medical financial issues, the ongoing debate surrounding in-office dispensing will continue.

Concepts in a multiprong approach to photoaging.

Photoaging is a multisystem degenerative process that involves the skin and the skin support systems, including the bone, cartilage, and subcutaneous compartments. These structures provide the architectural support for the dermis, epidermis, and stratum corneum. A multiprong approach to photoaging involves reversing the undesirable changes in each of these structures. Dermatologists should become adept at treating all of the visible manifestations of photoaging.

Cosmetics in acne and rosacea.

Cosmetics that are appropriate for use in patients with rosacea and acne must be noncomedogenic, nonacnegenic, nonirritating, and hypoallergenic. This requires a basic understanding of cosmetic fromulation and the selection of products that meet guidelines for sensitive skin.

Degradation and migration of facial foundations.

The surface characteristics of a facial foundation on the skin affect not only photoprotection, but also aesthetic appearance. A 400x video microscope was used to study the movement of facial foundation on the face of 12 female subjects with oily, dry, and normal skin in a controlled environment over 8 hours. This evaluation revealed gradual degradation of the cosmetic film and accumulation of facial foundation pigment particles in the follicular ostia. This cosmetic migration decreases photoprotection and may explain the perifollicular nature of some cutaneous reactions to facial foundations.

Comparison of treatment of acne vulgaris with alternate-day applications of tazarotene 0.1% gel and once-daily applications of adapalene 0.1% gel: a randomized trial.

Tazarotene and adapalene are recently introduced topical retinoids that are useful in the treatment of acne vulgaris. The clinical benefits of each drug have now been compared in a multicenter, double-blind, randomized, parallel-group study involving 164 patients with mild-to-moderate facial acne vulgaris. Patients were randomized to receive 15 weeks' treatment with alternate-day tazarotene 0.1% gel, with vehicle gel on the intervening evenings, or once-daily adapalene 0.1% gel. Both regimens were comparably effective with no significant between-group differences in efficacy measures. A total of 74% of tazarotene-treated subjects and 73% of adapalene-treated subjects achieved at least a 50% improvement in their acne. In addition, there were no clinically significant differences in tolerability. It is concluded that an alternate-day tazarotene regimen offers efficacy and thus tazarotene treatment can be useful even in patients whose compliance may be suboptimal. An alternate-day regimen also offers the potential for considerable savings in drug costs.

Physicians' and patients' perspectives on office-based dispensing: the central role of the physician-patient relationship.

OBJECTIVE: To describe physicians' and patients' reasons for participating in office-based sales of dermatologic products. DESIGN: Survey data on the attitudes, opinions, and beliefs of dermatologists and their patients were analyzed. SETTING: A market research study of office-based selling. PARTICIPANTS: Thirty dermatologists involved in direct selling from the office, 20 dermatologists not involved in direct selling, 22 patients who purchase products from their dermatologists' offices, and 25 office managers. MAIN OUTCOME MEASURE: The hypotheses of this study were formulated after the market research study had been done. The main outcome measure was the physicians' and patients' reported reasons for patients purchasing skin care products from dermatologists rather than from retail stores. RESULTS: "Trust" was the most frequent reason cited by physicians for patient purchases, while "physician knowledge" was the most frequent reason cited by the purchasing patients. The most common location to display the products was the waiting room (20 [67%] of the physicians). The most common types of products sold included glycolic acid products (15 [50%]), moisturizers (13 [43%]), sunscreens (12 [40%]), and alpha-hydroxy acid products other than glycolic acid (9 [30%]). CONCLUSION: The interaction between physicians who sell products in their offices and their patients is highlighted by 2 key elements of the physician-patient relationship: trust and physician knowledge.

A dermatologist's perspective on the final sunscreen monograph.

The final sunscreen monograph, released on May 21, 1999, defined the upper limit for sun protection factor rating to 30+, revised the list of accepted active agents allowed in sunscreens, and changed the permissible wording of product labeling. These changes are important to the dermatologist who uses sunscreens as part of skin cancer prevention.

Hydrogel barrier/repair creams and contact dermatitis.

BACKGROUND: Barrier creams are important to protect the skin in occupations with chemical exposure. The value of hydrogels in barrier creams has never been studied. OBJECTIVE: The purpose of this study was to evaluate the current technology in barrier cream formulation and explore the utility of hygrogels in skin protection. METHODS: A total of 80 men, women, and children between the ages of newborn to 80 years >were studied with the following dermatologic conditions: household hand dermatitis (21), occupational hand dermatitis (18), latex glove irritant contact dermatitis (9), diaper dermatitis (5), cutaneous wounds (17), and allergic contact dermatitis (ACD) (10). In this study, the investigators used a split body approach, in a double-blind randomized fashion, where one body site was treated with a traditional petrolatum-based cream while the other body site was treated with a hydrogel-based barrier/repair cream. Both subject and investigator assessments were recorded by questionnaire. RESULTS: The hydrogel barrier/repair cream showed better skin improvement than the petrolatum-based cream in both subject assessment (62%, P =.0048) and investigator assessment (75%, P =.0000003). CONCLUSION: Hydrogel barrier/repair creams might represent a new, effective approach to skin protection.

Cosmetics and skin care products. A historical perspective.

The history of cosmetics and skin care products parallels many important technologic developments in chemistry, materials, and packaging innovations. Much is revealed about ancient civilizations by the cosmetics that are uncovered in archaeologic excavations. Much can also be said about modern-day health and adornment practices based on products in the current marketplace.

Therapeutic moisturizers.

Moisturizers have been adapted to perform many important roles on the skin surface. Simple moisturizers combine occlusives and humectants to enhance the water-holding capacity of the skin. The addition of carefully selected emollients can influence the esthetic properties of the moisturizer and the stability of the active ingredients. The addition of sunscreens to moisturizers has created a new product category with an added skin function. Further diversity in moisturizer formulation is created through the addition of specialty ingredients, designed to enhance the functioning of the skin. Moisturizers are an important part of the dermatologist's armamentarium.

Colored facial cosmetics.

Colored cosmetics are an important part of the dermatologic armamentarium. They can camouflage contour and pigment abnormalities, provide moisturization, enhance oil control, add sun protection, deliver barrier-enhancing agents, increase acne treatment, and create a sense of personal well-being. Familiarity with these products allows the dermatologist to provide better patient care.
