Which statement correctly identifies a biosimilar for Remicade?

• A. Filgrastim-sndz (Zarxio) is a biosimilar for Remicade.
• B. Adalimumab-dabb is a biosimilar for Remicade.
• C. Etanercept-simb is a biosimilar for Remicade.
• D. Infliximab-dyyb (Inflectra) is a biosimilar for Remicade.

Answer: (D)

Biosimilars are highly similar versions of a proven biologic product, with no meaningful differences in safety, purity, or potency. Remicade is the brand name for infliximab, a monoclonal antibody that blocks TNF. A true biosimilar for Remicade would be another infliximab product approved to treat the same conditions. Infliximab-dyyb, sold as Inflectra, is that biosimilar to infliximab and is used for the same indications. The other options are biosimilars for different reference biologics (filgrastim, adalimumab, etanercept), not for infliximab.
