• History of significant hypersensitivity to lotilaner or any related products (including excipients of the formulations) as well as severe hypersensitivity reactions (like angioedema) to any drugs.
• Presence or history of significant gastrointestinal, metabolic, liver or kidney disease, or surgery that may affect drug bioavailability (excluding appendectomy).
• History of significant cardiovascular, pulmonary, hematologic, neurological, psychiatric, endocrine, immunologic, or dermatologic disease.
• Have a history of malignancy (or active malignancy), with the exception of treated basal cell or squamous cell carcinoma.
• Presence of clinically significant ECG abnormalities at Screening, as defined by the Investigator.
• Maintenance therapy with any drug or significant history of drug dependency or alcohol abuse.
• Any clinically significant illness in the 28 days prior to study treatment administration.
• Known history of chronic infectious disease.
• History of allergy to surgical tape, hydrocolloid, or dressing.
• History of severe reactions to tick bites (granuloma or systemic reactions).
• Use of any non-prescription or prescription drugs (with the exception of hormonal contraceptives, hormone replacement therapy, acetaminophen) in the 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to study treatment administration.
• Use of St. John's wort in the 28 days prior to study treatment administration.
• Intake of lotilaner in the 6 months prior to study treatment administration.
• Treatment with an investigational drug within 30 days or 5 times the half-life (whichever is longer) prior to Screening.
• History of live attenuated vaccine within 4 weeks prior to randomization or requirement to receive these vaccinations at any time during the study.
• Any other clinically significant abnormalities in laboratory test results at Screening that would, in the opinion of the Investigator, increase the participant's risk of participation, jeopardize complete participation in the study, or compromise interpretation of study data.
