INDICATIONS AND USAGE XDEMVY is indicated for the treatment of Demodex blepharitis. CONTRAINDICATIONS None. WARNINGS AND PRECAUTIONS Risk of Contamination Do not allow the tip of the dispensing container to contact the eye, surrounding structures, fingers, or any other surface in order to minimize contamination of the solution. Serious damage to the eye and subsequent loss of vision may result from using contaminated solutions. Use with Contact Lenses Contact lenses should be removed prior to instillation of XDEMVY and may be reinserted 15 minutes following its administration. ADVERSE REACTIONS Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. XDEMVY was evaluated in 833 patients with Demodex blepharitis in two randomized, double-masked, vehicle- controlled studies (Saturn-1 and Saturn-2) with 42 days of treatment. The most common ocular adverse reaction observed in controlled clinical studies with XDEMVY was instillation site stinging and burning which was reported in 10% of patients. Other ocular adverse reactions reported in less than 2% of patients were chalazion/ hordeolum and punctate keratitis. USE IN SPECIFIC POPULATIONS Pregnancy: Risk Summary There are no available data on XDEMVY use in pregnant women to inform any drug associated risk; however, systemic exposure to lotilaner from ocular administration is low. In animal reproduction studies, lotilaner did not produce malformations at clinically relevant doses. Data Animal Data In an oral embryofetal developmental study in pregnant rats dosed during organogenesis from gestation days 6-19, increased post-implantation loss, reduced fetal pup weight, and incomplete skeletal ossification were observed at 50 mg/kg/day (approximately 1390 times the recommended human ophthalmic dose (RHOD) on a body surface area basis) in the presence of maternal toxicity (i.e., decreased body weight and food consumption). A rare malformation of situs inversus of the thoracic and abdominal viscera occurred in 1 fetus from a pregnant rat receiving 50 mg/kg/day; whether this finding was treatment-related could not be excluded. No maternal or embryofetal toxicity was observed at 18 mg/kg/day (approximately 501 times the RHOD on a body surface area basis). In an oral embryofetal development study in pregnant rabbits dosed during organogenesis from gestation days 7-19, no embryofetal toxicity or teratogenic findings were observed at 20 mg/kg/day (approximately 580-times the RHOD on an AUC basis), even in the presence of maternal toxicity (i.e., decreased food consumption and body weight). In an oral two-generation reproductive toxicity study, F0 male and female rats were administered lotilaner at doses up to 40 mg/kg/day for 10 weeks before pairing and during the 2-week pairing period (3 weeks for males). Dosing for F0 females continued through lactation day 22. F1 male and female rats were administered lotilaner at 1 and 5 mg/kg/day post-weaning from day 23 for 10 weeks before pairing and during the 2-week pairing period (3 weeks for males). Dosing for F1 parenteral females continued through lactation day 22. There were no clear adverse effects on the F1 generation, and a slightly lower mean body weight during lactation was noted for F2 pups at 5 mg/kg/day. The no observed adverse effect level (NOAEL) was determined to be 5 mg/kg/day (approximately 139 times the RHOD on a body surface area basis). Lactation: Risk Summary There are no data on the presence of XDEMVY in human milk, the effects on the breastfed infant, or the effects on milk production. However, systemic exposure to lotilaner following 6 weeks of topical ocular administration is low and is >99% plasma protein bound, thus it is not known whether measurable levels of lotilaner would be present in maternal milk following topical ocular administration. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for XDEMVY and any potential adverse effects on the breast-fed child from XDEMVY. Pediatric Use: Safety and effectiveness in pediatric patients below the age of 18 years have not been established. Geriatric Use: No overall differences in safety or effectiveness have been observed between elderly and other adult patients. NONCLINICAL TOXICOLOGY Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Long-term studies in animals have not been performed to evaluate the carcinogenic potential of lotilaner. Mutagenesis Lotilaner was not genotoxic in the following assays: Ames assay for bacterial gene mutation, in vitro chromosomal aberration assay in cultured human peripheral blood lymphocytes, and in vivo rat micronucleus test. Impairment of fertility In a two-generation study of reproductive performance in rats, F0 male and female rats were administered lotilaner at oral doses of 40 mg/kg/day for 80 days reduced to 20 mg/kg/day for 47-50 supplementary days. Reduced pregnancy rates and decreased implantation rates were observed in F0 females at doses 20 mg/kg/day) (approximately 556 times the RHOD on a body surface area basis), which were also associated with maternal toxicity (i.e., decreased body weight and food consumption). No effects on fertility were observed in F0 females at the dose of 5 mg/kg/day (approximately 139 times the MRHOD on a body surface area basis). No effects on fertility were observed in F0 males at the oral dose of 20 mg/kg/day (approximately 556 times the RHOD on a body surface area basis), and no effects on fertility were observed in F1 males and females at the oral dose of 5 mg/kg/day (approximately 139 times the RHOD on a body surface area basis). PATIENT COUNSELING INFORMATION Handling the Container Instruct patients to avoid allowing the tip of the dispensing container to contact the eye, surrounding structures, fingers, or any other surface in order to minimize contamination of the solution. Serious damage to the eye and subsequent loss of vision may result from using contaminated solutions. When to Seek Physician Advice Advise patients that if they develop an intercurrent ocular condition (e.g., trauma or infection), have ocular surgery, or develop any ocular reactions, particularly conjunctivitis and eyelid reactions, they should immediately seek their physician's advice concerning the continued use of XDEMVY. Use with Contact Lenses Advise patients that XDEMVY contains potassium sorbate, which may discolor soft contact lenses. Contact lenses should be removed prior to instillation of XDEMVY and may be reinserted 15 minutes following its administration. Use with Other Ophthalmic Drugs Advise patients that if more than one topical ophthalmic drug is being used, the drugs should be administered at least 5 minutes between applications. Missed Dose Advise patients that if one dose is missed, treatment should continue with the next dose. RX only © 2024 Tarsus Pharmaceuticals, Inc. All rights reserved.

US--2300345 1/24 D uring the season of giving, you can help the ASCRS Foundation make a difference with your contribution to support essential programs, like Operation Sight, which helps provide cataract surgery to those who wouldn't otherwise have access to this sight-restoring procedure. We want to thank all those who have made a donation to help us in our important work. It's not too late to make your end-of-year donations to the ASCRS Foundation. Supporting the gift of sight and the education of those who deliver sight-restoring surgery is not limited to just one day. If you're thinking about gifts to get your colleagues, friends, and family for the holidays, consider giving the gift of sight through a donation to the ASCRS Foundation in their name. In his introduction to the issue (see page 4), EyeWorld Chief Medical Editor Sumit "Sam" Garg, MD, speaks about the benefits that charitable giving can have for members. In his comments, he noted that, "Donations to qualified or- ganizations like the ASCRS Foundation are tax deductible, allowing supporters to reduce their taxable income. These deductions can be especially valuable early in a medical ca- reer, as they create opportunities for financial planning and maximizing resources. This incentive encourages ongoing charitable contributions and underscores the importance of investing in causes like addressing preventable blindness." Dr. Garg also highlighted the option of a donor advised fund, which allows for an immediate tax benefit with the potential to allow the donated funds to grow over time with distributions to qualified charities at a future date. National Sight Week In October, ASCRS celebrated the 9th National Sight Week, along with World Sight Day. Operation Sight is the ASCRS Foundation's charitable cataract surgery program that op- erates in the U.S. This program, launched in 2014, serves financially vulnerable, uninsured individuals who cannot afford or access care. Since its inception, Operation Sight and its 800 volunteer surgeons have helped provide nearly 10,000 cataract surgeries. The ASCRS Foundation encouraged support for its sight-restoring work during National Sight Week, and you can continue this support year-round in a number of ways. 1. Make a tax-deductible donation and join the Lindstrom Legacy Gift Club. 2. Include ASCRS in your donor advised fund and/or planned giving.
