The Food and Drug Administration has approved a prefilled pen formulation of Dupixent (dupilumab; Sanofi and Regeneron), providing another option for administering the treatment.

The Dupixent prefilled pen delivers 300mg of dupilumab in 2mL of solution for subcutaneous injection. It is only indicated for use in adults and adolescents aged 12 years and older. To help with administration, the prefilled pen includes visual and audio cues, as well as a hidden needle and a single-press injection. Like the prefilled syringe, use of the prefilled pen requires training by a healthcare professional.

Commenting on the approval, George D. Yancopoulos, MD, PhD, Co-founder, President and Chief Scientific Officer at Regeneron, said: “The Dupixent prefilled pen was specifically designed to provide patients with an easy-to-use, convenient option so they can feel more comfortable administering their injections.”   

The prefilled pen is expected to be available in the third quarter of 2020. The prefilled syringe, both in 200mg and 300mg doses, will continue to be available as well.
