The CHMP has issued a positive opinion recommending that the dosing interval for Libtayo be extended from three weeks to six weeks. This change would apply to all approved cancer indications in the European Union following an initial 12-week course of treatment.
Why it matters
Extending the dosing interval could simplify treatment regimens for patients across the European Union. A final decision on the proposal now rests with the European Commission, which is expected to issue a ruling within two months.
The CHMP recommends transitioning to a six-week dosing interval after an initial 12-week treatment period. This decision arrives alongside Regeneron's recent report of $4.29 billion in revenue and $1.3 billion in net income for the second quarter of 2026.
