Inflation Reduction Act Targets Biologic Patents to Speed Biosimilar Savings
-
The Inflation Reduction Act could curb patent practices that delay biosimilar market entry by selecting drugs like Enbrel and Stelara for price negotiation.
-
Biologics account for a large portion of drug spending, so biosimilars can provide big savings, but originators use patent thickets to block competition.
-
Patent litigation has delayed many approved biosimilars from launching. Legislation to restrict patent practices has advanced but passage is uncertain.
-
In Europe, more biosimilars are approved and see faster, greater uptake due to purchasing practices favoring lowest cost.
-
U.S. originators have more leverage to block competition versus Europe, but the IRA's drug selections suggest a desire to accelerate biosimilar timelines.
