Coverage of First Humira Biosimilar Varies on ‘Big Three’ PBMs’ Formularies

Following the launch of Amgen Inc.’s Amjevita (adalimumab-atto), a slew of other FDA-approved Humira (adalimumab) biosimilars entered the U.S. market in July under settlement agreements with Humira originator AbbVie Inc. Major PBMs quickly announced that they would add more biosimilars to their formularies to compete with Humira.

At the end of June, UnitedHealth Group’s Optum Rx said it will place Boehringer Ingelheim's Cyltezo (adalimumab-adbm) and Sandoz's Hyrimoz (adalimumab-adaz) on its formulary at parity with Humira starting July 1. The Cigna Group’s Express Scripts then said it would add three biosimilars — Cyltezo, Hyrimoz and adalimumab-adaz (the unbranded equivalent of Hyrimoz) — to its list of preferred drugs.
