Women could be the biggest consumers of biosimilars … but they don’t know much about them

Europe pioneered the use of biosimilars in 2006, and they started slowly gaining traction in the United States three years later, in 2009. That's when Congress created the Biologics Price Competition and Innovation Act (BPCI Act) to increase competition in the pharmaceutical marketplace. Five years have passed since the FDA approved the United State's first biosimilar, Sandoz's Zarxio, which reduces the risk of infection in patients receiving strong chemotherapy that can cause a low white blood cell count.

Some of the diseases treated by biosimilars disproportionately impact women. For example, midlife women bear the biggest burden of chronic conditions such as breast cancer and autoimmune diseases such as rheumatoid arthritis, which can be treated by biosimilars.

Many biosimilars aren’t making it to the pharmaceutical market

To date, the FDA has approved 28 biosimilars, but only a few of them are currently available on the market. And it's more than marketing tactics keeping them from getting there. Although they were manufactured to increase market competition and meaningfully decrease the price of expensive biologics, some makers of reference medications have delayed their entry to market by entering litigation that claims biosimilars infringe on patents that protect biologics.

To date, nearly every biosimilar manufacturer faces, or has faced, such legal action. This has big repercussions for consumers who need options for less expensive medications. Hadlima, for example, a biosimilar to Humira that treats arthritis, plaque psoriasis and Crohn's disease, among other health conditions, can't be sold in the United States because of ongoing litigation and patent issues.

And even when biosimilars do make it to the market, due to the high costs of litigation, makers of these medications can't lower their costs as much as expected, which means they haven't yet lived up to the goal of the BPCI Act to increase market competition and substantially decrease prices. Without increased competition, biologics and the few biosimilars that have come to market continue to be among the most expensive drugs available, making it difficult for many women to afford them.

A way forward

In 2018, the FDA published its Biosimilars Action Plan (BAP) for the purpose of "balancing innovation and competition." BAP not only acknowledged the FDA's important role in increasing access to biosimilars, but it also recognized barriers to increasing both the development and adoption of these drugs, including the need to increase public awareness.

In addition, the FDA has identified education as a necessary factor to the successful development and adoption of biosimilars, and it has done a fantastic job creating educational materials about these new drugs. Yet for biosimilars to truly get a foothold in the pharmaceutical market, the FDA must continue to support increased outreach to patients.

Our 2019 survey showed that 65% of women would probably use affordable medicines if they were able to access them. By building confidence about the cost and safety of biosimilars and their equivalence to biologics, consumers may start demanding that more of these drugs make it to market.

Women can take matters into their own hands by asking their healthcare providers for information about biosimilars, such as what they know about biosimilars, whether there's a biosimilar to use instead of the medicine they're currently prescribed for their condition, and what their healthcare provider knows about the research that demonstrates the safety and efficacy of biosimilars.

It's important for the FDA to reauthorize the BsUFA. It will not only provide resources to review new biosimilars, it will also allow the FDA to create accessible and understandable educational campaigns to answer questions like these.

I suspect the number of people able to attain biosimilars — especially women living with chronic conditions — would dramatically increase as more people learn how biosimilars could improve their lives.
