Description

Dupilumab is intended for patients whose eczema is not controlled adequately by topical therapies, or those for whom topical therapies are not advisable. Dupilumab can be used with or without topical corticosteroids. FDA approval on March 28, 2017.
Indication
Dupilumab is a monoclonal antibody designed for the treatment of atopic diseases such as eczema.
Mechanism of Action
It binds to the alpha subunit of the interleukin-4 receptor (IL-4Rα). Through blockade of IL-4Rα, dupilumab modulates signaling of both the interleukin 4 and interleukin 13 pathway.
Pharmacokinetics
- Absorption
- Following an initial subcutaneous (SC) dose of 600 mg, dupilumab reached peak mean ±SD concentrations (Cmax) of 70.1±24.1 mcg/mL by approximately 1 week post dose. Steady-state concentrations were achieved by Week 16 following the administration of 600 mg starting dose and 300 mg dose either weekly (twice the recommended dosing frequency) or every other week. Across clinical trials, the mean ±SD steady-state trough concentrations ranged from 73.3±40.0 mcg/mL to 79.9±41.4 mcg/mL for 300 mg administered every 2 weeks and from173±75.9 mcg/mL to 193±77.0 mcg/mL for 300 mg administered weekly. The bioavailability of dupilumab following a SC dose is estimated to be 64%.
