Documented Uses

• In combination with [thymidine], doxecitine is indicated for the treatment of thymidine kinase 2 deficiency (TK2d) in adults and pediatric patients with an age of symptom onset on or before 12 years.
• Take with food. Food increases drug Cmax and AUC.
• Doxecitine is administered orally, with rapid absorption and plasma concentrations returning to near baseline within 8 to 12 hours. The absolute bioavailability of doxecitine following oral administration has not been determined. The median time to peak plasma concentration (Tmax) was approximately two hours for doxecitine.
• Urinary excretion of intact doxecitine and doxribtimine was <1% of the dose in healthy subjects following an oral administration of doxecitine and doxribtimine.
• In vitro plasma protein binding of doxecitine was less than 10% over the concentration range between 0.23 mcg/mL and 23 mcg/mL.
• Doxecitine is primarily degraded by cytidine deaminase to its nucleobases and the 2-deoxy-α-D-ribose 1-phosphate moiety. Intermediate products of doxecitine catabolism are deoxyuridine, uracil, and dihydrouracil with the end products β-alanine, ammonia, and carbon dioxide (CO2).
