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.
