EXTON, PA, Jan. 22, 2024 (GLOBE NEWSWIRE) -- Since the first US FDA-approved tumor necrosis factor (TNF) inhibitor in 2002 for the treatment of psoriatic arthritis (PsA), TNF’s have upheld their status as the primary standard of care. However, recent years have witnessed a transformative shift in both the US and EU markets, as rheumatologists increasingly favor alternative mechanisms, notably IL-17 inhibitors. The current IL-17 market includes Novartis’s Cosentyx, which gained first-to-market status in the US in 2015, followed by Eli Lilly’s Taltz five years later, challenging the historical dominance of TNFs.
According to data from Spherix Global Insights’ RealTime Dynamix™: Psoriatic Arthritis (EU), the inclination of rheumatologists (n=257) toward TNFs as their preferred Mechanism of Action (MOA) experienced a substantial decline from the close of 2022 to the conclusion of 2023. In contrast, within that timeframe, rheumatologists saw a preference for IL-17s more than double, indicating a noteworthy transformation in treatment preferences.
Over half of rheumatologists cite efficacy as their primary motive for favoring IL-17 inhibitors in PsA treatment, regularly underscoring the class’s success in treating both skin and joint manifestations. One rheumatologist expresses:
“I feel that it is the best MOA because it is target specific for PsA and it is effective in treating joints, skin as well as dactylitis.”
This trend of transitioning away from TNFs amongst rheumatologists is expected to persist with the recent EU approval of UCB’s Bimzelx, as highlighted by early adoption in Germany. Physicians project a decline in the prescribing of TNFs, with Bimzelx expected to double in share upon launching into other EU markets. Notably, rheumatologists consistently express a preference for Cosentyx over Taltz, a sentiment likely to strengthen with the introduction of an intravenous formulation.
While awaiting approval in the US, Bimzelx has gained significant interest, as indicated by Spherix's pre-launch metrics, encompassing familiarity, satisfaction, degree of advance, and candidacy. A substantial portion of US rheumatologists anticipate prescribing Bimzelx to their PsA patients within the first three months of commercial availability.
As the treatment landscape for PsA undergoes dynamic changes, staying ahead of these shifting trends becomes essential for effective patient management and optimal treatment outcomes. The evolving preferences among rheumatologists highlight the growing significance of IL-17 inhibitors, setting the stage for a new era of PsA management.
