OptumRx will offer Amjevita and two other biosimilars alongside Humira. OptumRx is the first PBM to make public its plans for the seven Humira biosimilars that could be introduced in 2023.
Beginning in 2023, OptumRx plans to include on its formularies Amgen’s Amjevita, a biosimilar of AbbVie’s blockbuster rheumatoid arthritis drug Humira (adalimumab), as well as two additional biosimilars, chief executive officer Heather Cianfrocco announced at a session of the recent HLTH2022.
“The coming wave of biosimilars is a pivotal opportunity to reduce cost and increase access to care for millions of people,” she said in a statement. “OptumRx fully supports advancement of the biosimilar market as part of our commitment to providing patients and providers with high quality and affordable care, flexibility, and choice.”
The new biosimilars will be available on the Select and Premium formularies, according to a company spokesperson. No information has been provided on tiering or utilization management strategies that could be employed.
Humira is a widely prescribed drug, with worldwide sales of more than $20 billion in 2021. Specialty drug costs, including Humira, represent 2% of prescriptions, yet account for 50% of drug cost spend with continued growth anticipated and are projected to reach $505 billion by 2023. Potential savings related to biosimilars could exceed $100 billion over the next five years.
Next year, seven biosimilars are expected to be launched, with Amjevita being the first in January. The others expected to launch in the second half of the year include: Organon's Hadlima, Boehringer Ingelheim’s Cyltezo, Coherus BioSciences’ Yusimry, Viatris’ Hulio, Sandoz’ Hyrimoz, and Pfizer’s Abrilada.
OptumRx leaders said they estimate double-digit client net cost improvement in 2023 compared with 2022 as a result of the Humira biosimilars. “Our independent pharmacy & therapeutics committee has reviewed all the FDA-approved biosimilars to maintain clinical quality of care,” the company said in a statement. “Biosimilars added at parity will optimize patient, provider, and client choice and flexibility.”
