Now That Humira Biosimilars Have Launched, What Are Lessons Learned for Stelara Biosimilars?

Following the launch of almost 10 biosimilars of AbbVie Inc.’s Humira (adalimumab) this year, 2025 will be another big year for the U.S. biosimilar market, when no less than three versions of Stelara (ustekinumab) from the Janssen Pharmaceutical Companies of Johnson & Johnson are set to become available. Having the experience of assessing multiple competitors with varying attributes could help payers as they prepare for the launches, say industry experts.

Stelara is a human interleukin-12 (IL-12) and -23 (IL-23) antagonist indicated for the treatment of adults with moderately to severely active Crohn’s disease, adults with moderately to severely active ulcerative colitis, people at least 6 years old with moderate-to-severe plaque psoriasis who are candidates for phototherapy or systemic therapy and people at least 6 years old with active psoriatic arthritis.
