Incyte Announces Results of Phase 3 Clinical Trials Evaluating Ruxolitinib Cream 1.5% (Opzelura®) in Patients with Prurigo Nodularis (PN) at 2025 American Academy of Dermatology Annual Meeting

- Full data from the Phase 3 TRuE-PN1 study, presented today in a late-breaking oral presentation, showed the study met all primary and key secondary endpoints

- Topline data from a separate Phase 3 study, TRuE-PN2, showed that while the primary endpoint did not reach statistical significance, the primary and all key secondary endpoints were in favor of ruxolitinib cream 1.5% versus vehicle

- These Phase 3 data will inform planned discussions with regulatory authorities on submission

WILMINGTON, Del.--(BUSINESS WIRE)-- Incyte (Nasdaq:INCY) today announced 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®), a topical JAK1/2 inhibitor, in adult patients (≥18 years) with prurigo nodularis (PN). The positive TRuE-PN1 data were presented as a late-breaking oral presentation (Session: S028 – Late-Breaking Research: Session 1) today at the 2025 American Academy of Dermatology (AAD) Annual Meeting, being held March 7–11, 2025, in Orlando.

The TRuE-PN1 study met its primary endpoint demonstrating that significantly more PN patients who applied ruxolitinib cream 1.5% versus vehicle control achieved a ≥4-point improvement from baseline in Worst-Itch Numeric Rating Scale (WI-NRS4) at Week 12 (44.6% vs 20.6%; P=0.0003). Significant itch improvements were observed with ruxolitinib cream 1.5% versus vehicle control at Day 7 (22.4% vs 8.0%; P=0.0064), with numerical improvements versus vehicle control reported at earlier timepoints. Additionally, the TRuE-PN1 study met all key secondary endpoints, including:

• Significantly more patients who applied ruxolitinib cream 1.5% versus vehicle control achieved an Investigator's Global Assessment for Stage of Chronic Prurigo Treatment Success (IGA-CPG-S-TS) at Week 12 (15.8% vs 3.9%; P=0.0048).
• As a result, significantly more patients who applied ruxolitinib cream 1.5% versus vehicle control achieved overall treatment success (11.9% vs 2.9%; P=0.0164), defined by patients achieving both WI-NRS4 response and an IGA-CPG-S-TS at Week 12; and,
• Significantly more patients treated with ruxolitinib cream 1.5% versus vehicle control also achieved WI-NRS4 at Week 4 (29.7% vs 12.7%, P=0.0034).

"PN is a challenging condition characterized by intensely itchy nodules that significantly impact patients' quality of life,” said Jim Lee, M.D., Ph.D., Group Vice President, Inflammation and Autoimmunity, Incyte. “These positive results display improvement in itch reduction and skin clearance, reinforcing the potential of ruxolitinib cream to become an effective topical treatment option that will help people living with PN."

Additionally, topline data from the Phase 3 TRuE-PN2 clinical trial demonstrated a strong positive trend across all key secondary endpoints, particularly for IGA-CPG-S-TS at Week 12 and WI-NRS4 at Day 7 (nominal P-value
