Nemolizumab is associated with a rapid improvement in atopic dermatitis signs and symptoms: subpopulation (EASI ≥ 16) analysis of randomized phase 2B study
Bibliographic record
Abstract
BACKGROUND: Nemolizumab is a humanized anti-IL-31 receptor blocker in phase 3 for atopic dermatitis (AD). OBJECTIVE: Analyse onset of action of nemolizumab 30 mg and compare efficacy and safety vs placebo (SC q4wk plus loading dose) in moderate-to-severe AD. METHODS: Post hoc analysis of patients with Eczema Area and Severity Index (EASI) scores ≥ 16 from a phase 2b trial of moderate-to-severe AD. Endpoints were change in EASI score at week 16, peak pruritus numeric rating scale (PP-NRS), Investigator's Global Assessment (IGA), changes in sleep and responders with ≥ 4-point improvement on PP-NRS. RESULTS: There was a significantly greater itch relief apparent by Day 2 (-22.8% vs -12.3% PP-NRS; P = 0.005) which continued to improve through week 16 (-68.5% vs -30.9% PP-NRS; P < 0.001). At week 16, PP-NRS ≥ 4-point response of itch was observed in 68.0% nemolizumab vs 15.9% placebo patients (P ≤ 0.001). There was also a rapid improvement of sleep disturbance with nemolizumab 30 mg, with a significant separation from placebo by Day 3 (-26.6% vs -9.0%; P < 0.001) which further improved till week 16 (-76.0% vs -36.5%; P < 0.001). Also for the EASI score a separation between groups in favour of nemolizumab was observed by week 1 (P ≤ 0.001), which increased through week 16 (-68.6% vs. -42.6%; P = 0.002). Finally, the degree of response was greater in nemolizumab-treated patients; clinically relevant reductions of 75% EASI were observed in 50.0% of nemolizumab patients versus 15.9% of placebo patients, while 90% reductions were reported for 36.0% and 6.8% of patients, respectively (P < 0.001 for both). IGA success (score of 0/1) was 32.0% for nemolizumab vs 6.8% for placebo (P = 0.002). Nemolizumab was safe and well-tolerated in this population; nasopharyngitis and upper respiratory tract infection were the most common adverse events. CONCLUSIONS: Nemolizumab resulted in very rapid, sustained improvements of inflammation, pruritus and sleep in patients with EASI ≥ 16 at baseline.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
