Sustained Improvements in Clinical and Patient-Reported Outcomes and Quality of Life Through 5 Years Among Ixekizumab-Treated Patients with Complete Clearance of Scalp Psoriasis by Week 60
Bibliographic record
Abstract
INTRODUCTION: Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin-17A, is approved for the treatment of moderate-to-severe plaque psoriasis. Since scalp psoriasis can be burdensome and challenging to treat with non-systemic therapies, this post hoc analysis focused on scalp psoriasis in patients with moderate-to-severe plaque psoriasis and baseline scalp involvement. The analysis considered a holistic concept of clearance through 5 years of ixekizumab treatment. METHODS: Ixekizumab-treated patients with baseline scalp involvement were pooled from three multicenter, randomized, double-blind, placebo-controlled, phase 3 trials (integrated UNCOVER-1/2 and UNCOVER-3). Analyses were performed on a subpopulation of patients who achieved complete resolution of scalp psoriasis at Week 60 (i.e., Week 60 Psoriasis Scalp Severity Index [PSSI-0] responders) and on the overall patient population (i.e., Week 60 PSSI-0 responders and non-responders), which was used as a reference. Clinical outcomes (PSSI), patient-reported outcomes (Itch Numeric Rating Scale [NRS] score, Skin Pain Visual Analogue Scale [VAS]), quality of life (Dermatology Life Quality Index [DLQI]), and concurrent outcomes were assessed from baseline through 5 years. Descriptive statistics of observed data were reported. RESULTS: After 60 weeks of ixekizumab treatment, 88.4% (UNCOVER-1/2) and 75.9% (UNCOVER-3) of patients with baseline scalp involvement achieved complete clearance (PSSI-0) of scalp psoriasis. Substantial improvements in the clinical outcomes (PSSI), patient-reported outcomes (Itch NRS, Skin Pain VAS), and quality of life (DLQI) were achieved by Week 60 and sustained through Week 264 in the Week 60 PSSI-0 responders and in the overall patient population. Additionally, a significant proportion of Week 60 PSSI-0 responders achieved concurrent complete scalp and skin clearance and quality of life improvement through 5 years. CONCLUSIONS: Continued treatment with ixekizumab provided long-term sustained scalp clearance over 5 years to patients with moderate-to-severe plaque psoriasis and baseline scalp involvement, and holistic improvements occurred across clinical outcomes, patient-reported outcomes, and quality of life. CLINICAL TRIAL NUMBERS: NCT01474512 (UNCOVER-1), NCT01597245 (UNCOVER-2), and NCT01646177 (UNCOVER-3).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
