FDA approved amivantamab and hyaluronidase-lpuj, marketed as Rybrevant Faspro, for subcutaneous injection across all indications approved for intravenous amivantamab.

The approval is primarily a delivery-route change, but route matters in oncology operations because infusion time, chair capacity and patient burden affect access.

Subcutaneous versions can make established therapies easier to deliver if safety, dosing and workflow are managed well.

Why It Matters

Formulation changes can meaningfully alter cancer-care logistics even when the target biology is unchanged.

What to Watch

Watch clinic adoption, payer rules and whether subcutaneous delivery reduces treatment burden.
