Abstract: The invention provided methods of treating viral infections, such as COVID-19, by providing an agent that inhibits a nucleotide synthesis pathway. In certain methods, the agent is an inhibitor of dihydroorotate dehydrogenase, such as a brequinar. In certain methods, brequinar is provided to a subject according to a dosing regimen that tailors levels of the drug in the lungs to achieve optimal therapeutic benefit. The dosing regimen may include defined levels of brequinar administered to the subject or defined levels of brequinar attained the lungs of the subject. The invention also provides combination therapies in which an inhibitor of dihydroorotate dehydrogenase is provided together with a second therapeutic agent.

Abstract: The invention provides methods for adjusting a drug dosing regimen, including a drug dosage and schedule of administration, in individuals who have previously received at least one dose of the drug. Adjustments to the dosage and/or schedule are made based on measured levels of the drug or metabolite of the drug and a biomarker of engagement of the drug with its target. The methods are useful for administration of therapeutic agents, such as brequinar, that alter metabolic pathways.
