Abstract

fetched live from OpenAlex

Abstract Itch is a major complaint among patients with seborrheic dermatitis (SD). Roflumilast is a selective, nonsteroidal, highly potent phosphodiesterase-4 inhibitor under investigation as a once-daily foam for treatment of SD. This phase 3 randomized, parallel-group, double-blind, vehicle-controlled trial (NCT04973228) was conducted in patients ≥9 years old with at least moderate SD affecting scalp and/or nonscalp areas. Patients were randomized 2 : 1 to apply once-daily roflumilast foam 0.3% (n = 304) or vehicle (n = 153) for 8 weeks. The primary efficacy endpoint was Investigator Global Assessment (IGA) success (IGA of Clear or Almost Clear plus ≥2-grade improvement from baseline) at Week 8. Secondary efficacy endpoints included Worst Itch Numeric Rating Scale (WI-NRS), which was completed daily by patients. Safety and local tolerability were also evaluated. Overall, significantly more roflumilast-treated patients than vehicle-treated patients achieved IGA success (79.5% vs. 58.0%; P < 0.0001) and IGA status of Clear (50.6% vs. 27.7%; P < 0.0001) at Week 8. Significantly greater percentages of roflumilast- than vehicle-treated patients had ≥4-point improvement on WI-NRS at Weeks 2 (32.7% vs. 15.5%; P = 0.0016), 4 (47.6% vs. 29.1%; P = 0.0007) and 8 (62.8% vs. 40.6%; P = 0.0001). Greater improvement in itch was observed among roflumilast-treated patients as early as 48 h after the first application (mean percent change from baseline: −27.87% vs. −13.11%; nominal P = 0.0024). Local tolerability and safety were favorable. Once-daily roflumilast foam provided improvement across multiple efficacy endpoints including rapid itch improvement, while demonstrating favorable safety and tolerability.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
