New biosimilars for Janssen Biotech, Inc.'s Remicade (infliximab) have helped to moderate costs for Crohn's disease as they’ve launched over the last two years, but plans still rely on utilization management strategies to keep the cost of treating the condition under control, experts tell AIS Health.
Additional biosimilars — notably, three biosimilars for AbbVie Inc.'s Humira (adalimumab) — eventually will enter the marketplace as well, but the Humira biosimilars currently are mired in patent litigation and likely won't launch until 2023, says April Kunze, Pharm.D., senior director, clinical formulary development and trend management strategy at Prime Therapeutics LLC.
Even though biosimilars don't reduce the cost of care as much as generics, "more competition has led to decreases in costs," Kunze says. Immunomodulator biosimilars Inflectra (infliximab-dyyb) and Renflexis (infliximab-abda) both have launched over the last two years in the U.S. — Pfizer Inc.'s Inflectra in late 2016 and Merck & Co. Inc.'s Renflexis in mid-2017.
Biologics represent the biggest slice of Crohn's drug costs. Most of the non-biologic agents have generic equivalents available, while the biologics are dominated by brand name products, even though over the past year or so, infliximab biosimilars have introduced competition to Remicade, says Beckie Fenrick, Pharm.D., senior partner-consulting, RemedyOne.
