Panelists discuss how the future of psoriasis treatment is evolving toward more personalized approaches with earlier biologic intervention for patients with high-impact disease regardless of body surface area, improved assessment tools that better capture disease burden, greater consideration of comorbidities and quality-of-life impacts, increased diversity in clinical trials, expanded patient education, innovative delivery systems, combination therapies, and targeted treatments for specific psoriasis phenotypes—all aimed at addressing current treatment gaps and moving closer to disease modification rather than merely symptom management.

Dosing Interval Differences in Psoriasis and Psoriatic Arthritis Treatment

SPECTREM was the first randomized controlled trial to evaluate biologics in this patient population. What other clinical trial data are there on the use of biologics for difficult-to-treat areas?

Panelists discuss how although SPECTREM was groundbreaking as the first randomized controlled trial specifically targeting moderate psoriasis in high-impact areas, other valuable evidence exists including subgroup analyses from pivotal trials of interleukin-17 inhibitors (secukinumab, ixekizumab, brodalumab) showing efficacy for scalp and nail psoriasis, dedicated studies like GESTURE (secukinumab for palmoplantar psoriasis), IXORA-Q (ixekizumab for genital psoriasis), data on TNF inhibitors for inverse/intertriginous disease, and observational real-world evidence supporting various biologics for difficult-to-treat locations—though most preceding studies were limited by focusing on patients with higher overall body surface area rather than the clinically important population with limited but high-impact disease that SPECTREM specifically addressed.

Examining the Relationship Between Psoriasis and Psoriatic Arthritis

a.	A high proportion of patients were able to achieve complete skin clearance (IGA 0) across all special sites at week 16 (Glick, 2024).
i.	Scalp 60% vs placebo 9%
ii.	Face 76% vs placebo 24%
iii.	Intertriginous 77% vs placebo 24%
iv.	Genital 73% vs placebo 33%
b.	No new safety signals identified.

Panelists discuss how the SPECTREM trial (Glick, 2024) revealed guselkumab’s exceptional site-specific efficacy for psoriasis in traditionally difficult-to-treat areas, achieving complete clearance (Investigator’s Global Assessment [IGA] 0) in remarkably high proportions of patients compared with placebo—with 60% clearance in scalp (vs 9% for placebo), 76% in facial sites (vs 24%), 77% in intertriginous areas (vs 24%), and 73% in genital regions (vs 33%)—while maintaining a favorable safety profile without new signals, demonstrating the biologic’s particular value for patients with limited but high-impact disease in these psychologically and functionally significant locations.

Key Takeaways on the Role of Oral JAK Inhibitors in Atopic Dermatitis Management

What are some key takeaways or advice for other dermatologists treating patients with atopic dermatitis with JAK inhibitors?

Experts discuss key takeaways for dermatologists managing atopic dermatitis with JAK inhibitors, emphasizing the importance of individualized treatment plans, monitoring for safety and efficacy, and balancing the benefits of JAK inhibitors with potential risks, especially in long-term use.
