Crisaborole

Overview

11 DESCRIPTION EUCRISA contains 2% crisaborole (w/w) in a petrolatum-based, white to off-white ointment and is for topical use. The active ingredient, crisaborole, is a phosphodiesterase-4 (PDE-4) inhibitor. Crisaborole is described chemically as 5-(4-cyanophenoxy)-1,3-dihydro-1-hydroxy-[2,1]-benzoxaborole. The empirical formula is C 14 H 10 BNO 3 and the molecular weight is 251.1 g/mol.

Mechanism of Action

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Crisaborole is a phosphodiesterase 4 (PDE-4) inhibitor. PDE-4 inhibition results in increased intracellular cyclic adenosine monophosphate (cAMP) levels. The specific mechanism(s) by which crisaborole exerts its therapeutic action for the treatment of atopic dermatitis is not well defined. 12.2 Pharmacodynamics Cardiac Electrophysiology At therapeutic doses, EUCRISA ointment is not expected to prolong QTc to any clinically relevant extent. 12.3 Pharmacokinetics Absorption The PK of EUCRISA were investigated in 33 pediatric subjects 2 to 17 years of age with mild to moderate atopic dermatitis and a mean ± SD body surface area (BSA) involvement of 49 ± 20% (range 27% to 92%).
