Biosimilars: Advancing Treatment Options and Improving Patient Lives

The recent developments in biosimilars are creating waves in the world of rheumatology and beyond, offering promising solutions to improve patient care. However, understanding the complexities of these treatments and their integration into healthcare systems is crucial for ensuring their benefits are fully realized.


CEO, Tiffany Westrich-Robertson, of The International Foundation of Autoimmune and Autoinflammatory Arthritis brings the latest updates on biosimilars from The 2024 American College of Rheumatology annual scientific meeting. 

What Are Biosimilars?

Biosimilars are near-identical alternatives to biologic drugs, designed to provide the same therapeutic benefits. They are often developed as lower-cost options, making treatments more accessible to patients. Despite their potential, the adoption of biosimilars in the United States lags behind other regions like Europe due to systemic challenges.

Why Biosimilars Matter to Patients?

Cost-Effective Treatment: Biosimilars promise to reduce the financial burden of biologic therapies, which are often prohibitively expensive. By introducing competition, they can lower overall healthcare costs and expand access.


Access to Advanced Therapies: Patients in need of biologic treatments may find biosimilars more readily available, especially in regions where cost is a barrier.


Challenges in the U.S.

While the benefits of biosimilars are evident, their rollout in the U.S. has faced roadblocks:


Insurance and PBM Dominance:  Pharmacy Benefit Managers (PBMs) hold significant sway over drug availability, often favoring biosimilars manufactured by companies they own. This consolidation can limit patient options and raise ethical concerns.


Non-Medical Switching:  Patients may be switched from one drug to another for reasons unrelated to medical necessity, disrupting continuity of care. This practice, known as non-medical switching, is a major concern for those with chronic conditions.

Biosimilars Class

Biosimilars, which are safe and effective alternatives to the original biologic, will have slight variations in non-active ingredients due to manufacturing differences. While some patients may be fine to "switch", it should be a choice between the patient and the doctor.

The Global Perspective

In Europe, regulations ensure that biosimilars can only be substituted for biologics with a doctor’s approval. This safeguard, known as interchangeability, protects patients by keeping treatment decisions in the hands of healthcare professionals. The U.S. is set to introduce a similar model in 2025, but with a critical difference: pharmacy-level substitution may occur without doctor approval. This raises questions about patient safety and autonomy.

How Research and Advocacy Can Improve Patient Lives

Informed Decisions: Ongoing research into biosimilar safety and efficacy equips patients and providers with the knowledge needed to make informed treatment choices.


Advocacy for Patient-Centric Policies: Organizations and individuals must advocate for policies that preserve doctor-patient collaboration in treatment decisions. Patients should not face non-medical switching unless it’s deemed beneficial by their healthcare team.


How Patients Can Stay Empowered


  • Know Your Rights: Understand the implications of switching treatments and when it is or isn’t appropriate.
  • Share Your Experiences: Positive and negative patient stories can guide advocacy and improve practices.
  • Engage in Advocacy: Support efforts to maintain medical integrity and protect access to the most effective treatments.


A Collaborative Future

Biosimilars have the potential to transform healthcare, but their success hinges on prioritizing patient needs and collaboration. By staying informed, sharing experiences, and advocating for thoughtful integration, patients and providers can work together to unlock the full benefits of these groundbreaking treatments.
