XdemvyTM (Lotilaner Ophthalmic Solution) 0.25% Topical Solution for the Treatment of Demodex Blepharitis.

XdemvyTM (lotilaner ophthalmic solution) 0.25% topical solution was recently approved for the treatment of Demodex blepharitis in adults aged ≥18 years. As an antiparasitic agent, lotilaner selectively inhibits gamma-aminobutyric acid chloride channels specific to the parasite and induces spastic paralysis, leading to death of Demodex blepharitis mites. In two randomized, double-masked, vehicle-controlled, multi-center, phase-3 clinical trials (Saturn-1 and Satuirn-2), lotilaner 0.25% topical solution was investigated for the treatment of Demodex blepharitis. Patients were assigned to receive either lotilaner 0.25% topical solution or vehicle (solution that did not contain lotilaner as an active ingredient) twice daily for 6 weeks. On day 43, lotilaner group demonstrated primary efficacy in achieving collarette cure ([collarette grade 0], Saturn-1: study group 44% [92/209], vehicle 7.4% [15/204]; Saturn-2: study group 56% [108/193], vehicle 12.5% [25/200]). Secondary efficacy was achieved by eradication of mite ([0 mite/lash], Saturn-1: study group 67.9% [142/209], vehicle 17.6% [36/304]; Saturn-2: study group 51.8% [99/193], vehicle 14.6% [29/200]), composite cure ([grade 0 collarette as well as grade 0 erythema], Saturn-1: study group 13.9% [29/209], vehicle 1.0% [2/204]; Saturn-2: study group 19.2% [37/193], vehicle 4% [8/200]), and erythema cure ([grade 0 erythema], study group 19.1% [40/209], vehicle 6.9% [14/204]; Saturn-2: study group 31.1% [60/193], vehicle 9.0% [18/199]). The adverse events were mild, with the most common being pain at instillation site. The recommended regimen for lotilaner 0.25% solution is one drop in each eye twice daily for 6 weeks.

LITFULOTM (Ritlecitinib) Capsules: A Janus Kinase 3 Inhibitor for the Treatment of Severe Alopecia Areata.

LITFULOTM (ritlecitinib) capsules were recently approved for the treatment of severe alopecia areata in adolescents and adults, aged ≥12 years. Ritlecitinib is the active ingredient and a dual inhibitor of Janus kinase 3 and the tyrosine kinase expressed in hepatocellular carcinoma kinase family. It prevents immune attack on the hair follicles that leads to hair loss. In a phase 2b-3 dose-dependant study, five doses of oral ritlecitinib and placebo administered once daily (QD) were investigated. Ritlecitinib demonstrated efficacy in achieving the primary outcome, Severity of Alopecia Tool (SALT) score of ≤20, at week 24 (31% [38/124] 200-mg ritlecitinib QD for 4 weeks, then 50 mg QD for 20 weeks; 22% [27/121] 200-mg ritlecitinib QD for 4 weeks, then 30 mg QD for 20 weeks; 23% [29/124] 50-mg ritlecitinib QD; 14% [17/119] 30-mg ritlecitinib QD; 2% [1/59] 10-mg ritlecitinib QD; and 2% [2/130] placebo). Mild to moderate common adverse effects were observed, which included headache, nasopharyngitis, and upper respiratory tract infection. The recommended regimen of ritlecitinib capsules is 50 mg QD with without food and swallowed whole.

ZORYVETM (Roflumilast) Cream: A Topical Phosphodiesterase-4 Inhibitor for the Treatment of Psoriasis.

ZORYVETM (roflumilast) cream is a topical phosphodiesterase-4 (PDE-4) inhibitor that has been recently approved for the treatment of plaque psoriasis. It is also indicated for use in intertriginous areas. Roflumilast, the active ingredient, inhibits PDE-4, leading to the suppression of pro-inflammatory immune responses in psoriatic lesions. Two phase 3 clinical trials have demonstrated the efficacy of once daily application of roflumilast to treat plaque psoriasis in patients aged 12 years and older. At week 8, an investigator's global assessment score of 0 or 1 with a grade 2 improvement from baseline, the primary efficacy end point, was observed in 39.1% (225/576) of patients applying roflumilast, compared to 6.6% (20/305) of patients applying vehicle. Common adverse events reported were diarrhea, headache, insomnia, nausea, pain at application site, upper respiratory tract infection, and urinary tract infection.

YCANTHTM (Cantharidin) Topical Solution.

YCANTHTM (cantharidin) topical solution has been approved recently for the treatment of molluscum contagiosum (MC) in children (aged ≥2 years) and adults. It works by activating serine proteases that lead to blistering and inflammation, promoting shedding of infected cells and viral clearance. In two phase-3, randomized, double-blind, vehicle-controlled trials of similar design, VP-102 (a drug-device combination, containing cantharidin 0.7% w/v and inactive ingredients, such as gentian violet, acetone, and denatonium benzoate, administered with an applicator) was investigated for the treatment of MC. VP-102 and vehicle were applied topically once every 21 days until complete clearance of lesions was observed, or for up to four treatments. Cantharidin demonstrated efficacy in achieving the primary outcome, at day 84/visit 4 (Cantharidin Application in Molluscum Patients [CAMP-1], VP-102: 46% [73/160], vehicle: 18% [19/106]; and CAMP-2, VP-102: 54% [81/150], vehicle: 13% [15/112]). Common adverse events were mild to moderate, such as lesions at the site of application, pruritus, and pain. The recommended regimen of cantharidin topical solution is its application once every 21 days until complete clearance of lesions is observed, or up to four treatments.

A Review of the Risk of Cow's Milk Protein Allergy in Oral Medication.

Immunoglobulin E (IgE)-mediated cow's milk allergy (CMA) is a common food reaction resulting from the consumption of cow's milk protein (CMP). The clinical manifestations of CMA include mild to severe urticaria, skin-manifested hypersensitivity reactions, and anaphylaxis. Food allergies may affect 8% of children and 10% of adults. The Federal Food, Drug, and Cosmetic Act (FD&C Act) requires that the label of a food must declare the presence of a "major food allergen" (MFA) contained in the food or ingredient. The Food and Drug Administration (FDA) generally regards milk protein concentrate (MPC) as safe for human consumption and use. The increasing use of MPC in formulations raises the need for its revelation in prescription and on labels of over-the-counter drugs. This review investigates oral and topical (including mucosal) preparations containing MPC for dermatologic and other uses and their therapeutic impact. Our findings suggest that for the adult population, the risk of serious cow's milk protein allergy (CMPA) from medications is minimal.

SOTYKTUTM (Deucravacitinib 6-mg Tablets)- A New Agent for the Management of Adult Plaque Psoriasis.

SOTYKTUTM (deucravacitinib) is a newly approved oral agent for managing moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy. Deucravacitinib is a highly selective allosteric tyrosine kinase 2 inhibitor targeting dysregulated cytokine responses in psoriasis patients. Its efficacy was demonstrated in two randomized, placebo- and active comparator-controlled phase 3 trials, where a significantly higher proportion of patients, up to 58.4% (194/332), achieved lessening of symptoms at week 16. The recommended dosing regimen of deucravacitinib is 6 mg once daily. More frequent adverse reactions occurring in the deucravacitinib-treated patients include upper respiratory infection (19.2% [161/840]), increase in blood creatine phosphokinase (2.7% [23/840]), herpes simplex infection (2.0% [17/840]), mouth ulcers (1.9% [16/840]), folliculitis (1.7% [14/840]), and acne (1.4% [12/840]). Continuance of treatment for up to week 52 did not increase the exposure-adjusted rates of adverse reactions. The selectivity and specificity of deucravacitinib treatment may improve its long-term safety profile, compared to other Janus kinase inhibitors.

Spesolimab, an anti-interleukin-36 receptor antibody, in patients with moderate-to-severe atopic dermatitis: Results from a multicentre, randomized, double-blind, placebo-controlled, phase IIa study.

BACKGROUND: Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease, and there is increasing evidence that the interleukin (IL)-36 pathway may play a role in the pathogenesis of AD. OBJECTIVES: To evaluate the efficacy and safety of spesolimab, a novel anti-IL-36 receptor antibody, in adult patients with moderate-to-severe AD. METHODS: In this phase IIa study, 51 eligible patients were randomized 2:1 to receive intravenous doses of spesolimab 600 mg or placebo every 4 weeks. The primary endpoint was the percentage change from baseline in Eczema Area and Severity Index (EASI) score at Week 16. RESULTS: The decrease in EASI score from baseline to Week 16 was -37.9% for spesolimab versus -12.3% for placebo (adjusted mean difference -25.6%, p = 0.149). A predefined sensitivity analysis, excluding data from patients who used restricted corticosteroids, resulted in an adjusted mean difference of -48.3% (nominal p = 0.024). Spesolimab was well tolerated, with no clinically relevant safety signals. CONCLUSIONS: This is the first study to evaluate the IL-36 pathway inhibition in AD. Although not statistically significant, numerical improvements were observed in the primary endpoint of change from baseline in the EASI score. Spesolimab had an acceptable safety profile, with no unexcepted safety concerns.

Olumiant® (Baricitinib)-A Newly Approved Janus Kinase Inhibitor for the Treatment of Alopecia Areata.

Olumiant® (Baricitinib) is a newly approved treatment for alopecia areata. Baricitinib is a selective and reversible inhibitor of Janus kinase that has shown promising results in two randomized, placebo-controlled phase-3 trials. A significantly higher number of patients achieved at least 80% scalp coverage following 36 weeks of treatment, compared to the placebo group. Adverse effects reported include acne and urinary tract infections, in addition to the warnings and precautions as highlighted in the product monograph. The current recommended regimen is 2 mg or 4 mg taken once daily, depending on the extent of hair loss. Other approved indications for baricitinib treatment include management of rheumatoid arthritis and the COVID-19 infections. (SKINmed. 2022;20:452-455).

VTAMA® (Tapinarof) Cream* for Plaque Psoriasis.

VTAMA® (Tapinarof) 1% cream is a newly approved topical agent for treating plaque psoriasis. The active ingredient, tapinarof, binds to and activates aryl hydrocarbon receptors that positively regulate immune response and skin homeostasis. Tapinarof has presented promising results in two identical phase 3 randomized, double-blind, vehicle-controlled trials, where the primary efficacy end points were observed in 35.4% and 40.2% of patients in the tapinarof group compared to 6.0% and 6.3% of patients in the vehicle group. Tapinarof was applied once daily to affected psoriasis lesions for 12 weeks. Adverse events associated with tapinarof application were folliculitis, contact dermatitis, and headache. (SKINmed. 2022;20:298-300).

Pharmacokinetics, Safety, Efficacy, and Biomarker Profiles During Nemolizumab Treatment of Atopic Dermatitis in Adolescents.

INTRODUCTION: Nemolizumab, a new monoclonal antibody that targets the receptor alpha of the neuroimmune cytokine interleukin-31 (IL-31), has shown efficacy in atopic dermatitis (AD) in adults. This study evaluated the pharmacokinetics (PK) and safety of nemolizumab in adolescents with moderate to severe AD as well as the relationship between nemolizumab concentrations and clinical efficacy and the effect of nemolizumab on protein biomarkers. METHODS: Open-label, 16-week study of nemolizumab in patients aged 12-17 years with moderate to severe AD (baseline EASI ≥ 16, IGA ≥ 3, and BSA ≥ 10%) and associated pruritus with baseline average daily peak pruritus numeric rating scale (PP-NRS) intensity of at least 4. Nemolizumab was administered subcutaneously as a loading dose of 60 mg at baseline, followed by 30 mg every 4 weeks until week 12 with background topical corticosteroids (TCS) or calcineurin inhibitors (TCI). Subsequently patients were followed for 8 weeks more. Stratum corneum (SC) and plasma samples were collected for biomarker assessments. RESULTS: Twenty patients participated, with a mean age of 14.8 ± 1.6 years. The PK of nemolizumab was described by a one-compartment model with linear elimination, a first-order absorption, and a mean half-life of 16.7 ± 4.1 days. Mean trough concentrations ranged from 2935 ± 1029 ng/mL to 3292 ± 2018 ng/mL over the 16-week treatment period. There was a marked improvement in rash, itch, and sleep with a decrease from baseline to week 16 in EASI by 66.5 ± 32.5%, in PP-NRS by 43.2 ± 37%, and in sleep disturbance numeric rating scale by 53.5 ± 47.8%. The popPK and PK/PD analyses confirmed that model-predicted exposure and efficacy of nemolizumab were similar in adolescents compared to adults receiving the same dosing regimens. Age did not impact PK parameters, while the main source of PK variability was body weight. Analyses of SC samples identified a panel of AD-related pro-inflammatory biomarkers that were upregulated in lesional skin (compared to non-lesional skin) and correspondingly downregulated in clinical responders to nemolizumab (based on EASI75 and PP-NRS ≥ 4). Four biomarkers (CCL20, CCL22, CCL27, and VEGF) had changes that were 1.9-3.5-fold higher in EASI responders than in EASI non-responders (all p < 0.05). Analysis showed no significant correlation between plasma biomarkers and clinical scores. Adverse events were experienced by 33.3% of subjects (n = 6) and were primarily mild or moderate in severity. CONCLUSIONS: Nemolizumab PK and safety profiles in adolescents with moderate to severe AD are consistent with previous nemolizumab studies in adults. PK/PD models demonstrate similar exposure-response profiles in 12- to 17-year-old adolescents and adults for three clinical endpoints (EASI, IGA, and PP-NRS). Nemolizumab treatment reversed AD-related pro-inflammatory biomarkers in skin, indicating that the neuroimmune cytokine IL-31 is an important mediator of multiple pathways in AD. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov NCT03921411.

JUBLIA (Efinaconazole 10% Solution) in the Treatment of Pediatric Onychomycosis.

Onychomycosis is a chronic fungal infection of the nails and is commonly observed in adults, especially the elderly, those who are diabetic, have poor peripheral circulation, and are immunocompromised; however, onychomycosis in children is being reported more frequently, especially in older children. There could also be a genetic predisposition to developing onychomycosis. Given that onychomycosis is uncommon in children, it is important to confirm the diagnosis mycologically. Treatment of onychomycosis includes oral or topical antifungal agents. In North America, the available oral antifungal agents are terbinafine, itraconazole, and fluconazole; however, none of these agents are approved by Food and Drug Administration (FDA) for children with onychomycosis. Terbinafine is, however, approved for tinea capitis in children aged 4 years and older. In general, these oral agents have been found to be safe and effective for pediatric onychomycosis. The available topical agents are efinaconazole solution 10%, tavaborole solution 5%, and ciclopirox nail lacquer topical solution 8%. The former two are approved by the FDA for the treatment of pediatric onychomycosis in children aged 6 years and older, while the third one is approved in children over the age of 12 years who have onychomycosis. In a phase-IV, multicenter, open label study, efinaconazole solution 10% was administered to children aged 6-16 years with culture positive, mild-to-severe distal and lateral subungual onychomycosis affecting ≥20% of at least one great toenail. Treatment was for 48 weeks, with follow-up at week 52. Efinaconazole solution 10% was found to be safe and well tolerated in this pediatric population. By week 52, the mycological cure was 65%, and the complete cure was 40%. The topical agents could be an important addition to the armamentarium of therapies available to treat pediatric onychomycosis safely and effectively.

Efficacy and Safety of Systemic Treatments for Skin and Joint Manifestations in Patients With Psoriasis.

Psoriasis is a chronic, systemic disease with features suggestive of autoimmune dysregulation. Patients with psoriasis vulgaris frequently experience systemic comorbidities, including cardiovascular and metabolic diseases, and approximately 30% develop psoriatic arthritis (PsA), which requires treatment. It is important that physicians and patients are aware of the breadth of treatment options available to treat the complete spectrum of psoriasis manifestations. This narrative review summarizes clinical information from approved systemic psoriasis therapies relevant to the treatment of PsA and related systemic pathologies. We include pivotal clinical trials of biologic therapies that are approved by the US Food and Drug Administration for psoriasis and PsA and additional studies identified from PubMed and congress abstract searches through August 21, 2019. We comment on the real-world effectiveness of traditional nonbiologic treatment options, including methotrexate, cyclosporine, acitretin, systemic corticosteroids, and nonsteroidal anti-inflammatory drugs and consider targeted synthetic and biologic disease-modifying antirheumatic drugs and their efficacy and safety in treating skin and joint manifestations. Finally, we discuss key considerations when managing patients with PsA as a comorbidity of psoriasis. The individual treatment needs of patients should be met while psoriasis and its systemic complications are managed. When addressing these needs, it is important to consider modern biologics and other systemic therapies.
