Efficacy of Roflumilast Foam, 0.3%, in Patients With Seborrheic Dermatitis: A Double-blind, Vehicle-Controlled Phase 2a Randomized Clinical Trial.

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.

Safety, Pharmacodynamic Response, and Treatment Satisfaction With OnabotulinumtoxinA 40 U, 60 U, and 80 U in Subjects With Moderate to Severe Dynamic Glabellar Lines.

BACKGROUND: OnabotulinumtoxinA 20 U reduces glabellar line (GL) severity at maximum frown for approximately 3 to 4 months. Small studies have suggested that >20-U doses may increase the efficacy and duration of response for GLs. OBJECTIVES: The aim of this study was to evaluate safety, pharmacodynamic response, and treatment satisfaction with onabotulinumtoxinA doses ≥20 U for GLs. METHODS: This 48-week, double-blind study compared 40, 60, and 80 U onabotulinumtoxinA vs 20 U and placebo in women with moderate or severe dynamic GLs on the Allergan Facial Wrinkle Scale. The following parameters were evaluated: the percentage of subjects with investigator-assessed ≥1-grade Facial Wrinkle Scale improvement from baseline at maximum frown (responders) at Week 24; the estimated median duration of response; the proportion of mostly/very satisfied responders on the Facial Line Satisfaction Questionnaire follow-up Items 1 to 5; and treatment-emergent adverse events. RESULTS: The modified intent-to-treat population (N = 226) had a mean age of 48.0 years, with similar baseline GL severity between treatment groups. Week 24 responder rates were 0% for placebo and 16.0%, 32.0%, 30.6%, and 38.5% for onabotulinumtoxinA 20, 40, 60, and 80 U, with significant (P < 0.05) differences for 40 and 80 U vs 20 U. Median duration of response was longer with all higher doses vs 20 U (≥24.0 vs 19.7 weeks; P < 0.05 vs 20 U at Week 24). Facial Line Satisfaction Questionnaire results indicated high subject satisfaction. The incidence and severity of treatment-emergent adverse events did not exhibit a dose-response effect. CONCLUSIONS: GL treatment with onabotulinumtoxinA doses >20 U demonstrated longer duration of response and higher patient-reported satisfaction vs the on-label 20-U dose with no apparent impact on safety variables.

Phase 2 randomized, dose-ranging trial of CTP-543, a selective Janus Kinase inhibitor, in moderate-to-severe alopecia areata.

BACKGROUND: Janus kinase (JAK) activation is suggested to have a pathological role in alopecia areata (AA). CTP-543, a deuterated compound that selectively inhibits JAK1 and JAK2, is being developed as an oral treatment for AA. OBJECTIVE: To assess the safety and efficacy of a 24-week regimen of CTP-543 in patients with chronic, moderate-to-severe AA. METHODS: In this phase 2, randomized, double-blind, placebo-controlled, sequential-design trial, patients were randomized to receive CTP-543 (4 mg, 8 mg, or 12 mg) or placebo every 12 hours for 24 weeks. RESULTS: A dose-related increase was observed in the percentage of patients with ≥50% relative reduction in Severity of Alopecia Tool scores from baseline at week 24 (9% placebo, 21% 4 mg twice daily, 47% 8 mg twice daily, and 58% 12 mg twice daily), with statistical significance versus placebo (P < .001) observed for the 8-mg twice daily and 12-mg twice daily groups, with differences from placebo noted as early as 12 weeks after the initiation of treatment. Safety results were consistent with the known safety profiles of JAK inhibitors. LIMITATIONS: These initial findings are from a relatively small controlled trial, and additional studies are needed to fully characterize the safety and efficacy of CTP-543 in adult patients with AA. CONCLUSIONS: Patients treated with CTP-543 (8 or 12 mg, twice daily) had a significant reduction in the severity of AA.

Setipiprant for Androgenetic Alopecia in Males: Results from a Randomized, Double-Blind, Placebo-Controlled Phase 2a Trial.

PURPOSE: To evaluate oral setipiprant versus placebo for scalp hair growth in men with androgenetic alopecia (AGA). PATIENTS AND METHODS: Males aged 18 to 49 years with AGA were enrolled in a double-blind, multicenter, 32-week, phase 2a trial; randomized to twice-daily (BID) 1000-mg (2×500 mg for a total daily dose of 2000 mg) setipiprant tablets or placebo for 24 weeks; and assessed at weeks 4, 8, 16, and 24, with a week 32 follow-up. The study initially included a finasteride 1-mg once-daily group, removed by protocol amendment. Changes from baseline to week 24 in target area hair count (TAHC) and blinded Subject Self-Assessment (SSA) of target area photographs were coprimary efficacy endpoints. Hair growth was also evaluated using blinded Investigator Global Assessment (IGA). Safety assessments included adverse events (AEs) and clinical laboratory tests. Analysis of covariance models were used to test statistical significance for TAHC, SSA, and IGA. Data were summarized without statistical analysis for finasteride. RESULTS: Randomized subjects (N=169) included 74 placebo, 83 setipiprant, and 12 finasteride subjects; 117 (69.2%) and 113 (66.9%) subjects completed week 24 and 32 visits, respectively. Treatment groups had similar baseline characteristics. Neither coprimary efficacy endpoint was met. At week 24, TAHC and SSA findings indicated no hair growth improvements with setipiprant versus placebo. Setipiprant also did not improve hair growth versus placebo per the IGA. Treatment-related AEs, all mild or moderate in severity, occurred in 12.3%, 25.9%, and 25.0% of the placebo, setipiprant, and finasteride groups, respectively. Two treatment-emergent serious AEs (TESAEs), cellulitis and multiple sclerosis, were reported in the placebo group, both unrelated to treatment. No TESAEs were reported with setipiprant or finasteride. CONCLUSION: Setipiprant 1000 mg BID was safe and well tolerated but did not demonstrate efficacy versus placebo for scalp hair growth in men with AGA.

Polymethylmethacrylate Collagen Gel-Injectable Dermal Filler for Full Face Atrophic Acne Scar Correction.

BACKGROUND/OBJECTIVES: This trial evaluated the effectiveness and safety of Bellafill for full-face acne scar treatment. PATIENTS AND METHODS: In this open-label, nonrandomized, multicenter pilot study investigating the use of polymethylmethacrylate for full-face atrophic acne scar correction, 42 adult subjects with a mean age of 43 years were treated and assessed for safety and effectiveness at Months 4 and 7. There were no hypersensitivity reactions to pretreatment skin testing or during scar treatments. RESULTS: At 4 and 7 months after initial treatment, 92% and 95% of subjects, respectively, were responders with ≥1-point improvement on the 5-point Acne Scar Assessment Scale. Subjects reported very high levels of improvement on the Global Aesthetic Improvement Scale (GAIS), with 95% of subjects reporting "improved or better" at 4 months and 90% at 7 months. The outcome of the physician GAIS was also high with 92% of patients classified as "improved or better" at 4 months and 97% at 7 months. There were only 2 device-related adverse events, both mild events related to Bellafill skin test (bruising, ecchymosis). There were no serious adverse events in response to the treatment product in this short-term follow-up study. CONCLUSION: Polymethylmethacrylate is effective for treating full-face acne scarring.

Once-Daily Oral Sarecycline 1.5 mg/kg/day Is Effective for Moderate to Severe Acne Vulgaris: Results from Two Identically Designed, Phase 3, Randomized, Double-Blind Clinical Trials.

BACKGROUND: Side effects may limit the use of current tetracycline-class antibiotics for acne. OBJECTIVE: Evaluate the efficacy and safety of once-daily sarecycline, a novel, narrow-spectrum tetracycline-class antibiotic, in moderate to severe acne. METHODS: Patients 9-45 years with moderate to severe facial acne (Investigator's Global Assessment [IGA] score ≥ 3, 20-50 inflammatory and ≤ 100 noninflammatory lesions, and ≤ 2 nodules) were randomized 1:1 to sarecycline 1.5 mg/kg/day or placebo for 12 weeks in identically designed phase 3 studies (SC1401 and SC1402). RESULTS: In SC1401 (sarecycline n=483, placebo n=485) and SC1402 (sarecycline n=519, placebo n=515), at week 12, IGA success (≥ 2-grade improvement and score 0 [clear] or 1 [almost clear]) rates were 21.9% and 22.6% (sarecycline), respectively, versus 10.5% and 15.3% (placebo; P less than 0.0001 and P equals 0.0038). Onset of efficacy in inflammatory lesions occurred by the first visit (week 3), with mean percentage reduction in inflammatory lesions at week 12 in SC1401 and SC1402 of -51.8% and -49.9% (sarecycline), respectively, versus -35.1% and -35.4% (placebo; P less than 0.0001). Onset of efficacy for absolute reduction of noninflammatory lesion count occurred at week 6 in SC1401 (P less than 0.05) and week 9 in SC1402 (P less than 0.01). In SC1401, the most common TEAEs (in ≥ 2% of either sarecycline or placebo group) were nausea (4.6% [sarecycline]; 2.5% [placebo]), nasopharyngitis (3.1%; 1.7%), headache (2.7%; 2.7%), and vomiting (2.1%; 1.4%) and, in SC1402, nasopharyngitis (2.5%; 2.9%) and headache (2.9%; 4.9%). Most were not considered treatment-related. Vestibular (dizziness, tinnitus, vertigo) and phototoxic (sunburn, photosensitivity) TEAEs both occurred in ≤ 1% of sarecycline patients. Gastrointestinal TEAE rates for sarecycline were low. Among females, vulvovaginal candidiasis (SC1401: 1.1% [sarecycline] and 0 [placebo]; SC1402: 0.3% and 0) and mycotic infection (0.7% and 0; 1.0% and 0) rates were low. CONCLUSION: The narrow-spectrum antibiotic sarecycline was safe, well tolerated, and effective for moderate to severe acne, with low rates of side effects common with tetracycline antibiotics.

Phase 3 Study of OnabotulinumtoxinA Distributed Between Frontalis, Glabellar Complex, and Lateral Canthal Areas for Treatment of Upper Facial Lines.

BACKGROUND: Although commonly practiced, simultaneous onabotulinumtoxinA injections to multiple facial areas have not been investigated in prospective studies. OBJECTIVE: Evaluate safety and efficacy of onabotulinumtoxinA for treatment of forehead lines (FHL) distributed between the frontalis (20 U) and glabellar complex (20 U), with or without simultaneous lateral canthal areas (crow's feet lines [CFL], 24 U) treatment. METHODS: Subjects with moderate to severe FHL were randomized (2:2:1) to onabotulinumtoxinA 40 U, onabotulinumtoxinA 64 U, or placebo. After 180 days, subjects could receive up to 2 additional open-label onabotulinumtoxinA 64 U treatments. RESULTS: The intent-to-treat (ITT) population comprised 787 subjects, and the modified ITT (mITT) population (subjects with psychological impact) comprised 568. After 30 days, onabotulinumtoxinA 40 U and 64 U significantly improved investigator- and subject-assessed FHL severity by at least 2 Facial Wrinkle Scale (FWS) grades in 45.6% and 53.0% of ITT subjects, respectively, versus 0.6% receiving placebo (both, p < .0001). Significantly more mITT subjects receiving onabotulinumtoxinA achieved investigator- and subject-assessed FWS ratings of none/mild versus placebo (p < .0001). OnabotulinumtoxinA was well tolerated. CONCLUSION: OnabotulinumtoxinA distributed between the frontalis and glabellar complex, with or without additional CFL injections, was safe and effective for treatment of moderate to severe FHL.

Treatment Response With Once-Daily Topical Dapsone Gel, 7.5% for Acne Vulgaris: Subgroup Analysis of Pooled Data from Two Randomized, Double-Blind Stu.

BACKGROUND: Acne vulgaris has varying physical and psychological effects in men and women of different ages, races, and ethnicities.

OBJECTIVE: This analysis assessed the relationship of age, sex, and race to treatment response with once-daily topical dapsone gel, 7.5%.

METHODS: We conducted a pooled subgroup analysis of 2 randomized, double-blind, vehicle-controlled clinical trials conducted in the US and Canada. The studies included patients with 20 to 50 inflammatory and 30 to 100 noninflammatory facial lesions, and a Global Acne Assessment Score (GAAS) of 3 (moderate). Pooled data (N=4340) were analyzed by age (12-17 and ≥18 years), sex, and race (Caucasian and non-Caucasian) for GAAS success (score of 0 [none] or 1 [minimal]) and mean percent change from baseline in inflammatory, noninflammatory, and total lesion counts. The impact of age and sex on treatment response was examined using multivariate analysis. Adverse events were analyzed by subgroups.

RESULTS: Treatment responses with dapsone gel, 7.5% were greater overall and for all subgroups versus vehicle. GAAS success rates and mean decrease in all lesion counts with dapsone gel, 7.5% were greater in older (aged ≥18 years) versus younger patients, and for females versus males. Treatment response with dapsone gel, 7.5% in racial subgroups was similar. Multivariate analysis showed statistical significance for age group and sex as predictors of GAAS success (P less than equal to .005) and reduction in lesion counts (P less than equal to .025). Adverse events were similar across subgroups.

CONCLUSIONS: Older age (≥18 years) and female sex were predictors of treatment response. These subgroups tended to have greater acne improvement in subgroup comparisons. Caucasian and non-Caucasian patients had similar responses. The safety profile of dapsone gel, 7.5% was similar across subgroups.

Open-Label Study Evaluating the Anti-Aging Effects of a 3-Product, 2-Step Retinol-Rejuvenation System Following 3 Months of Treatment in Subjects With Photodamage.

BACKGROUND: Photodamage to the skin occurs with exposure to sunlight (UVA or UVB) either intentionally or unintentionally, and can present in a variety of ways. It typically occurs on areas of chronic UV exposure, including the face, ears, and neck. METHODS: We evaluated the effects of a 3-product, 2-step retinol-rejuvenation system containing an exfoliating cleanser, a 0.5% retinol emollient cream, and SPF 30 moisturizing sunscreen used daily for 3 months on the appearance of mild-to-moderate facial photodamage in female subjects. RESULTS: Significant improvements in facial appearance could be observed as early as 2 weeks, with continued improvement over the duration of the study. There were no adverse events reported that were related to study product and reports of cutaneous tolerability issues were rare. CONCLUSIONS: A 3-product, 2-step retinol-rejuvenation system provides significant improvements in signs of photodamage and overall skin appearance, and is well-tolerated.

The Effects of a Daily Skincare Regimen on Maintaining the Benefits Obtained from Previous Chemical Resurfacing Treatments.

BACKGROUND: Chemical peels are versatile treatments that involve chemical exfoliation of the skin for cosmetic improvement. Deeper peels produce more significant results, but can be associated with longer healing time and potential complications. Novel chemical resurfacing treatments (AGE and MELA) were developed in Europe to produce skin resurfacing via controlled inflammation to promote cell regeneration with minimum negative effects associated with conventional peelings. The AGE Resurfacing regimen is indicated for the treatment of photoaging, and consists of multi-ingredient peeling solution with trichloroacetic acid, pyruvic acid, salicylic acid, mandelic acid, and lactobionic acid. The MELA Resurfacing regimen addresses hyperpigmentation concerns and contains mandelic acid, potassium azeloyl diglycinate, retinol, salicylic acid, phytic acid, lactobionic acid, and lactic acid. Results of previously conducted US clinical experience trial of AGE and MELA resurfacing protocols rated 81% of subjects with some level of improvement according to physician assessment.
OBJECTIVES: To evaluate whether a daily skin care regimen used for 12 weeks could maintain the benefits achieved with AGE and MELA chemical resurfacing treatments.
METHODS: Subjects who completed participation in the AGE and MELA skin resurfacing clinical trial were recruited to participate in a continuation trial and used a daily regimen of MDRejuvena facial products for 12 weeks. No other facial products were permitted. Physicians assessed the severity of individual skin parameters at baseline and week 12 and provided global assessment. Subjects assessed improvement of individual skin parameters at week 12 and provided an overall assessment.
RESULTS: Thirteen subjects participated in the 12-week continuation trial. According to the physician's global assessment, all subjects demonstrated some level of improvement at week 12 compared to baseline. Physician assessment showed a decrease in severity of all skin parameters assessed at week 12 compared to baseline. According to the subject overall assessment at week 12, 11 of 12 subjects noted some level of improvement, 1 subject saw no improvement, and 1 subject did not provide an overall assessment. Mild to moderate improvement was observed by subjects in all individual skin parameters assessed except for skin discoloration.
CONCLUSIONS: The results of the continuation study demonstrate that use of a daily skin care regimen, which include combination of 2 various strengths of MDRejuvena Rejuvaphyl® Rejuvenating Complex: low strength (LS) and high strength (HS), not only maintains but can enhance the beneficial effects of skin resurfacing treatments for at least 12 weeks.

OnabotulinumtoxinA for Treatment of Moderate to Severe Crow's Feet Lines: A Review.

Lateral canthal lines or crow's feet lines (CFL) may be treated with onabotulinumtoxinA. We identified several key concepts important to understanding the use of onabotulinumtoxinA for treatment of moderate-to-severe CFL. To contextualize and integrate data on the recommended dose and injection patterns of onabotulinumtoxinA for treatment of CFL, we summarized data from pivotal clinical studies in the development of onabotulinumtoxinA for treatment of CFL. Data from key studies of onabotulinumtoxinA for CFL are presented. The efficacy and safety of onabotulinumtoxinA treatment of moderate-to-severe CFL were evaluated in 2 randomized, controlled phase 3 studies comprising 1362 patients. The 24U total dose of onabotulinumtoxinA used in these studies was based on a phase 2 dose-ranging trial. Two injection patterns were available to investigators; each involved 3 injection sites per side in the lateral orbicularis oculi muscle. A cross-sectional analysis of photographs from the phase 3 trials provided detailed information on the frequency of 4 distinct CFL patterns. In the primary efficacy analysis for each phase 3 trial, CFL responder rates were significantly greater with onabotulinumtoxinA vs placebo at day 30 (P< .001). Eyelid edema (1%) was the only adverse event reported in ≥ 1% of patients receiving onabotulinumtoxinA, occurring more frequently with onabotulinumtoxinA than with placebo. The studies showed that onabotulinumtoxinA is effective and generally well-tolerated for CFL treatment. Additionally, 2 different injection patterns allow physicians to tailor treatment based on a patient's CFL pattern.

An evaluation of the safety and efficacy of bimatoprost for eyelash growth in pediatric subjects.

PURPOSE: Evaluate the safety and effectiveness of bimatoprost 0.03% for treatment of eyelash hypotrichosis in a pediatric population. PATIENTS AND METHODS: This multicenter, randomized, double-masked, parallel-group study was conducted at seven sites in the US and Brazil. Subjects with eyelash hypotrichosis caused by chemotherapy or alopecia areata (aged 5-17 years) or healthy adolescents aged 15-17 years were enrolled (N=71). Subjects applied bimatoprost 0.03% or vehicle to upper eyelid margins once nightly for 4 months and were followed for 1 month post-treatment. Eyelash prominence was assessed using the validated 4-grade Global Eyelash Assessment scale with photonumeric guide. Changes in eyelash length, thickness, and darkness were measured by digital image analysis. Safety was assessed by adverse events and ophthalmic observations. RESULTS: Eyelash prominence improved in a significantly greater proportion of subjects treated with bimatoprost compared with vehicle at month 4 (70.8% versus 26.1%; P<0.001). This benefit was sustained at month 5 post-treatment assessment. Digital image analysis measures were significantly improved with bimatoprost. Significant treatment benefits with bimatoprost versus vehicle were evident among the healthy adolescents but not in the postchemotherapy or alopecia areata subgroups. The safety profile of bimatoprost was consistent with previous studies in adults. CONCLUSION: Bimatoprost was safe and well tolerated in pediatric subjects with eyelash hypotrichosis. In this study with limited sample size, subgroup analyses showed that treatment was effective in healthy adolescents with no concurrent contributing medical condition, but not in those with eyelash hypotrichosis due to chemotherapy or alopecia areata.

Superior efficacy of calcipotriene and betamethasone dipropionate aerosol foam versus ointment in patients with psoriasis vulgaris--A randomized phase II study.

BACKGROUND: An aerosol foam formulation of fixed combination calcipotriene 0.005% (as hydrate; Cal) plus betamethasone dipropionate 0.064% (BD) was developed to improve psoriasis treatment. OBJECTIVES: To compare the efficacy and safety of Cal/BD aerosol foam with Cal/BD ointment after 4 weeks. METHODS: In this Phase II, multicenter, investigator-blind, 4-week trial, adult patients with psoriasis vulgaris were randomized to Cal/BD aerosol foam, Cal/BD ointment, aerosol foam vehicle or ointment vehicle (3:3:1:1). The primary efficacy endpoint was the proportion of patients at week 4 who achieved treatment success (clear or almost clear with at least a two-step improvement) according to the physician's global assessment of disease severity. RESULTS: In total, 376 patients were randomized. At week 4, significantly more patients using Cal/BD aerosol foam achieved treatment success (54.6% versus 43.0% [ointment]; p = 0.025); mean modified (excluding the head, which was not treated) psoriasis area and severity index score was significantly different between Cal/BD aerosol foam and Cal/BD ointment (mean difference -0.6; p = 0.005). Rapid, continuous itch relief occurred with both active treatments. One adverse drug reaction was reported with Cal/BD aerosol foam (application site itch). CONCLUSIONS: Cal/BD aerosol foam demonstrates significantly greater efficacy and similar tolerability compared with Cal/BD ointment for psoriasis treatment.

Safety and Effectiveness of the Hyaluronic Acid Filler, HYC-24L, for Lip and Perioral Augmentation.

BACKGROUND: Hyaluronic acid gels are increasingly used for augmentation of the lips. OBJECTIVE: To assess the safety and effectiveness of Juvéderm Ultra XC, a 24 mg/mL hyaluronic acid gel containing 0.3% (wt/wt) lidocaine (HYC-24L), for augmentation of the lips. METHODS: This ongoing, multicenter, single-blind study randomized 213 subjects to the treatment group (n = 157) or concurrent no-treatment control group that received delayed treatment (n = 56). The primary effectiveness endpoint was the responder rate (≥1 point improvement from baseline) based on the blinded evaluating investigator's assessment of the subject's overall lip fullness (or fullness of the eligible lip) using the validated Allergan 5-point Lip Fullness Scale. To meet this endpoint, the treatment group had to have a responder rate ≥60% and significantly greater than the treatment control group at Month 3. RESULTS: The primary endpoint was met, with a 79.1% responder rate for the treatment group and 26.1% for the treatment control group (p < 0.0001). More than half of subjects (56.4%) maintained treatment response for 12 months. Common injection site responses were swelling, bruising, and firmness; most were of mild or moderate severity. CONCLUSION: HYC-24L is safe and effective for aesthetic lip augmentation, with results lasting up to 1 year.

Safety and Efficacy of Bimatoprost for Eyelash Growth in Postchemotherapy Subjects.

OBJECTIVE: To evaluate long-term efficacy and safety of bimatoprost for treatment of chemotherapy-induced eyelash hypotrichosis. DESIGN: One-year, multicenter, double-masked, parallel-group study. SETTING: Twenty-one centers in the United States and one center in the United Kingdom. PARTICIPANTS: This study randomized (3:1) 130 subjects to bimatoprost 0.03% or vehicle applied topically to upper eyelid margins for six months. All subjects used bimatoprost for a second six months. MEASUREMENTS: Responders for the primary composite end point achieved ≥1-grade improvement in Global Eyelash Assessment score and ≥3-point improvement in Confidence, Attractiveness, and Professionalism domain score of the Eyelash Satisfaction Questionnaire at Month 4. Secondary assessments included eyelash length, thickness, and darkness, using digital image analysis. RESULTS: The responder rate was significantly higher with bimatoprost versus vehicle at Month 4 (37.5% vs. 18.2%; p=0.041) and Month 6 (46.9% vs. 18.2%; p=0.004). Significant improvements favoring bimatoprost occurred in eyelash length (p=0.008), thickness (p<0.001), or darkness (p=0.029) at Month 4, with similar results at Month 6 (p<0.001, length; p<0.001, thickness; p=0.002, darkness). Responder rates reached 61.5 percent at Month 12 for subjects continuing bimatoprost and 67.6 percent for those switched from vehicle to bimatoprost. Conjunctival hyperemia (16.7%) and punctate keratitis (9.4%) were the most common adverse events. CONCLUSION: Bimatoprost provides rapid eyelash recovery, whether started shortly after chemotherapy (4 to 12 weeks) or delayed for six months, with minimal adverse events. CLINICAL TRIAL REGISTRY: NCT00907426.

Efficacy and safety of onabotulinumtoxinA for the treatment of crows feet lines: a multicenter, randomized, controlled trial.

BACKGROUND: This study was part of a Phase 3 program treating crow's feet lines (CFL) with onabotulinumtoxinA. OBJECTIVE: To evaluate the efficacy and safety of onabotulinumtoxinA treatment of CFL. METHODS: This multicenter, double-blind, placebo-controlled, 5-month study randomized subjects with moderate-to-severe CFL (maximum smile) to onabotulinumtoxinA (24 U; n = 222) or placebo (n = 223). Investigators and subjects assessed CFL severity (maximum smile and rest) using the 4-grade Facial Wrinkle Scale (FWS). Co-primary end points were investigator- and subject-assessed proportion of subjects achieving a CFL FWS grade of 0 (none) or 1 (mild) at maximum smile (Day 30). Additional efficacy end points, patient-reported outcomes, and safety/adverse events (AEs) were evaluated. RESULTS: All primary and secondary end points were achieved; statistically significant differences favored onabotulinumtoxinA (p < .001, all comparisons vs placebo). Co-primary responder rates were 66.7% compared with 6.7% for investigator-assessed and 58.1% compared with 5.4% for subject-assessed response (onabotulinumtoxinA group and placebo, respectively; p < .001). A significantly greater proportion of the onabotulinumtoxinA group than placebo group achieved a 1 grade or greater improvement on the FWS (maximum smile and rest assessed by both the investigator and subject; all time points; p < .001). Most AEs were mild or moderate and did not result in discontinuations. CONCLUSION: Treatment of moderate-to-severe CFL with onabotulinumtoxinA was effective and well tolerated.

Anti-aging proof of concept study: results and summary.

BACKGROUND AND OBJECTIVES: The etiology of aging human skin includes intrinsic physiologic changes greatly accelerated by photoaging, predominantly through exposure to UV light. Consumer interest and demand for anti-aging skin care products is extremely high especially in light of aging populations. Prenatal (fetal) tissue has been shown to possess healing characteristics and regenerative effects. A proprietary tissue engineering technology has been developed to produce a soluble human extracellular matrix material with growth factors and proteins. Neonatal cells are cultured on microbeads under conditions of low oxygen tension. This human cell-conditioned media (hCCM) contains a variety of growth factors and cytokines similar to those found in fetal cells and has been incorporated into a topical preparation for use in facial wound healing (after laser resurfacing procedures) and improving the appearance of aging skin. The objective of this study was to observe the effects of an MRCx™-containing topical skincare regimen on subjects with demonstrated aging skin damage (photodamage) when used consistently over a 3 month time period. METHODS: Female subjects age 35-65 with Fitzpatrick Skin Type I-IV and mild to moderate amounts of photodamage, fine lines, and wrinkles used Regenica® Replenishing Crème and Regenica® Renew SPF 15 for 3 months. At each visit, photos were taken of subjects while investigators completed skin grading assessments and subjects completed self-assessments. Investigator assessments included evaluation of tactile roughness, visual texture, wrinkles, blotchiness, skin tone evenness, radiance, and translucence on a 5-point scale. Subjects' self-assessments included assessment of fine lines and wrinkles, firmness, evenness of skin tone, brightness, resilience, clarity, and radiance. Changes from baseline were evaluated for each parameter and P values for changes from baseline to each study visit for investigator's assessments and to end-of-study for self-assessments were calculated. RESULTS: Eighteen of 21 enrolled female subjects completed the study. Three subjects chose to drop from the study. Statistically significant improvements in investigator assessments of tactile roughness, visual texture, wrinkles, blotchiness, skin tone evenness, radiance and translucency compared to baseline were observed at weeks 4, 8, and 12 after initiating treatments. Progressive improvement was seen through the last study visit (visit 5, week 12). Similar statistically significant improvements in subjects' self-assessments were seen comparing the first post-baseline visit (visit 2, week 2) to subsequent visits. 93.5 % subjects agreed (somewhat or strongly) with all of the positive subject assessment statements at week 12. Importantly, 100 % of subjects indicated at the end of the study that they would recommend the product to a friend and would want to purchase the product. No treatment-related adverse events were recorded during the study. CONCLUSIONS: Regenica was safe and clinically effective in reducing anti-aging effects in this group of female subjects aged 35-65 years as measured by both investigator assessments and subjects' self-assessments.

A double-blind, randomized, multicenter, controlled trial of suspended polymethylmethacrylate microspheres for the correction of atrophic facial acne scars.

BACKGROUND: Acne scarring remains a stubborn clinical problem. Few treatments have been shown to be definitely effective for this problem. Polymethylmethacrylate (PMMA) microspheres in collagen (ArteFill, Suneva Medical Inc, Santa Barbara, CA) have shown long-term benefit for nasolabial fold treatment. A pilot study has shown benefit for PMMA-collagen in atrophic acne scarring. OBJECTIVE: We sought to demonstrate the safety and effectiveness of PMMA-collagen for acne scarring in a controlled, blinded trial. METHODS: Subjects with at least 4 moderate to severe rolling, atrophic scars randomly received PMMA-collagen or saline injections. Subjects underwent up to 2 injection sessions and were followed up for 6 months. Efficacy was assessed using a validated rating scale for each scar. RESULTS: In all, 147 subjects underwent injections. Success was achieved by 64% of those treated with PMMA-collagen compared with 33% of control subjects (P = .0005). The treatment showed excellent safety with generally mild, reversible adverse events. No significant differences in efficacy or safety were noted between genders, for darker skin types, or in older age groups. LIMITATIONS: Subjects were followed up for only 6 months. CONCLUSION: PMMA-collagen demonstrates substantial effectiveness in the treatment of atrophic acne scars of the face while maintaining an excellent safety profile. Further follow-up should be undertaken to demonstrate longer-term benefit and safety.

Open-label treatment of moderate or marked melasma with a 4% hydroquinone skin care system plus 0.05% tretinoin cream.

OBJECTIVE: To evaluate treating epidermal melasma using a 4% hydroquinone skin care system plus tretinoin 0.05% cream. DESIGN: Multicenter open-label study with all patients receiving above-mentioned treatment for up to 24 weeks. SETTING: Private dermatology and plastic surgery clinics and clinical research facilities. PARTICIPANTS: Thirty-seven adult females with moderate or marked epidermal melasma, melasma pigmentation of mild-to-marked intensity and Fitzpatrick skin type III to VI. MEASUREMENTS: Melasma severity melasma pigmentation intensity melasma improvement, patient satisfaction, quality-of-life measures, erythema, dryness, peeling, burning/stinging. RESULTS: No patient discontinued due to lack of efficacy or treatment-related adverse events. Treatment was associated with a significant reduction from baseline in melasma severity and melasma pigmentation intensity from Week 4 onward (P≤0.001), and 100 percent of patients showed improvement from Week 8 onward. At Week 24, 100 percent of patients were "satisfied" or "very satisfied" with the overall effectiveness of their treatment. Patients' quality of life also improved (e.g., the proportion of patients feeling embarrassed or self-conscious about their skin "a lot" or "very much" declined from 78 percent at baseline to four percent at Week 24). Mean and median scores for erythema, dryness, peeling, and burning/stinging did not exceed trace levels. CONCLUSION: Treating moderate-to-severe melasma using the 4% hydroquinone skin care system plus 0.05% tretinoin can significantly reduce the severity of melasma and the intensity of melasma pigmentation within four weeks. Treatment was generally well tolerated and associated with an improved quality of life and high levels of patient satisfaction.

A randomized, phase 2, dose-ranging study in the treatment of moderate to severe inflammatory facial acne vulgaris with doxycycline calcium.

BACKGROUND: Doxycycline calcium (WC2055) is a drug substance with a possible role in the treatment of acne. The objective of this study was to evaluate the safety and efficacy of three doses of doxycycline calcium tablets compared with placebo in the treatment of moderate to severe inflammatory facial acne vulgaris. METHODS: This was a randomized, double-blind, phase 2 dose-ranging study in subjects with moderate to severe inflammatory acne aged 12 years to 45 years. Subjects were randomized to receive doxycycline calcium tablets 0.6, 1.2, or 2.4 mg/kg/day or placebo, and instructed to take their tablets once daily for 12 weeks, in the evening at least 1 hour before or 2 hours after mealtime. The primary efficacy variables were the dichotomized Investigator's Global Assessment score (success or failure) at week 12 (success defined as ≥ 2 score decrease from baseline) and the absolute change from baseline to week 12 in inflammatory lesion count. RESULTS: A dose-response effect was seen with doxycycline calcium formulation in subjects with moderate to severe inflammatory acne. The highest dose-group (corresponding to approximately 2.4 mg/kg/day) showed a statistically significant difference from placebo. The dose-response effect was confirmed by logistic regression analysis for both treatment success and incidence of gastrointestinal adverse events. A limitation of this study is that safety and efficacy were only studied on moderate to severe inflammatory acne. Also, the study was not prospectively powered to show efficacy differences. CONCLUSION: Doxycycline calcium shows a dose-response effect in reducing inflammatory lesions in subjects with moderate to severe inflammatory acne.
