Competitive environment
Many treatment options for psoriatic arthritis are available today, and include therapies that work in a variety of ways. These include nonsteroidal anti-inflammatory drugs (NSAIDs), conventional Disease-Modifying Antirheumatic Drugs (DMARDs) (e.g., sulfasalazine, methotrexate), injectable biologic DMARDs, and other oral DMARDs. These other oral DMARDs include Otezla (apremilast), and JAK (Janus kinase) inhibitors such as Rinvoq (upadacitinib) and Xeljanz (tofacitinib).
Sotyktu is a selective tyrosine kinase 2 (TYK2) inhibitor, a first-in-class treatment. While TYK2 inhibitors can be considered a subset of JAK inhibitors, they are highly selective for the TYK2 enzyme alone. This selectivity allows Sotyktu to be effective while improving safety. Most notably, Sotyktu does not have the boxed warnings seen with traditional JAK inhibitors, including serious infections, mortality, malignancy, major adverse cardiovascular events (e.g., death, non-fatal heart attack) and thrombosis (i.e., blood clots inside blood vessels).
Comparing effectiveness indirectly, Sotyktu had higher response rates compared to Otezla but lower than Xeljanz and Rinvoq. However, it is difficult to compare results across multiple trials due to differences in study populations.
In addition to competing with branded biologic and non-biologic DMARDs, several biosimilars are available for psoriatic arthritis, including biosimilars to Humira® (adalimumab) and Stelara® (ustekinumab).
The oral treatment landscape is also expected to grow with J&J’s new treatment, icotrokinra. J&J has filed for FDA approval for icotrokinra to treat plaque psoriasis with expected approval in 2026. The response rates for icotrokinra for plaque psoriasis appear to be numerically better than other oral drugs, including Sotyktu. Icotrokinra is also being developed for psoriatic arthritis, but data is not yet available for this indication.
The estimated wholesale acquisition cost for Sotyktu based on its current availability for plaque psoriasis is approximately $83,0000 per year. In comparison, the estimated wholesale acquisition cost for Rinvoq is approximately $81,000.
