New to biosimilars?

  • Biosimilars are biological products that are highly similar to and have no clinically meaningful differences from existing, FDA-approved reference biologics.
  • While biosimilars are similar to their reference biological product, they are not generic equivalents.
  • Biosimilars go through a rigorous FDA review process including analytical, animal and clinical studies.

Biosimilars go through an extensive FDA approval process and offer safe, effective therapeutic options for serious diseases

As more biosimilars become available in the U.S., providers, payers and patients all stand to benefit from further incorporating these safe and effective therapies throughout our healthcare ecosystem.

Rising healthcare costs, increasing drug production demands and reimbursement pressures are all putting a serious strain on our nation’s healthcare delivery system. By adopting biosimilars routinely into patient treatment decisions, we can improve overall access to critical, life-saving drugs all while reducing the costs of these expensive therapies through increased competition.
