Oral spleen tyrosine kinase/Janus Kinase inhibitor gusacitinib for the treatment of chronic hand eczema: Results of a randomized phase 2 study
Bibliographic record
Abstract
BACKGROUND: Gusacitinib is an oral inhibitor of Janus and Spleen tyrosine kinases. METHODS: The efficacy and safety of gusacitinib were evaluated in a double-blind, placebo-controlled, multicenter, phase 2 study in 97 chronic hand eczema patients randomized (1:1:1) to placebo or gusacitinib (40 or 80 mg) for 12 weeks (part A). Then, in part B (through week 32), the patients received gusacitinib. RESULTS: At week 16, patients receiving 80 mg gusacitinib showed a 69.5% (P <.005) decrease in the modified total lesion-symptom score versus 49.0% for 40 mg (P =.132), and 33.5% for placebo. Considerable improvement in Physician's Global Assessment was seen in 31.3% of patients receiving 80 mg versus 6.3% of placebo (P <.05). A 73.3% decrease in the hand eczema severity index versus placebo (21.7%) occurred in patients receiving 80 mg (P <.001). Patients receiving 80 mg experienced a considerable decrease in hand pain (P <.05). As early as week 2, considerable reductions over placebo in modified total lesion-symptom score (P <.005), Physician's Global Assessment (P =.04), and hand eczema severity index (P <.01) were observed (80 mg gusacitinib). Adverse events included upper respiratory infection, headache, nausea, and nasopharyngitis. CONCLUSIONS: Gusacitinib showed rapid improvement in chronic hand eczema patients and was well tolerated, warranting further investigations.

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.
