On Saturday, Incyte Corporation (NASDAQ:INCY) revealed results from its pivotal Phase 3 TRuE-PN clinical trial program –TRuE-PN1 and TRuE-PN2 studies – evaluating the safety and efficacy of twice-daily ruxolitinib cream 1.5% (Opzelura) in adult patients with prurigo nodularis (PN), a chronic skin condition characterized by very itchy firm lumps.

The data were presented at the 2025 American Academy of Dermatology (AAD) Annual Meeting.

Significant itch improvements were observed with ruxolitinib cream 1.5% versus vehicle control at Day 7 (22.4% vs. 8.0%), with numerical improvements versus vehicle control reported at earlier timepoints. Additionally, the TRuE-PN1 study met all key secondary endpoints, including:

Additionally, topline data from the Phase 3 TRuE-PN2 clinical trial demonstrated a positive trend across all key secondary endpoints at Day 7 (nominal P-value <0.05 for both).

While the primary endpoint favored ruxolitinib cream 1.5% versus vehicle, it did not reach statistical significance due to the high placebo response.

William Blair analyst Matt Phipps sees the TRuE-PN study results as disappointing, but they don't impact Incyte valuation since the model didn't factor in Opzelura's potential for PN. The company considers PN a smaller market for Opzelura, generating less than $1 billion, compared to its use for atopic dermatitis and vitiligo.

Price Action: INCY stock is up 0.92% at $71.44 at the last check Monday.
