A81 POOLED SAFETY ANALYSIS FROM THE USTEKINUMAB CROHN’S DISEASE AND PSORIATIC DISEASES PHASE 2 AND 3 TRIALS
Bibliographic record
Abstract
Ustekinumab (UST) is well-established in psoriasis (PsO) & psoriatic arthritis (PsA) with up to 5 years safety data from psoriasis clinical trials with 3117 pts & 8998 patient years (PY). However, limited safety data have been presented in Crohn’s disease (CD). In CD, Phase 2/3 data show that UST is safe & effective. Here we present CD safety data & compare it to safety from psoriatic diseases. Safety data from 5 CD (2 Ph2/3Ph3) trials were analyzed with the previously reported PsO (1 Ph2/3Ph3) & PsA (1 Ph2/2 Ph3) trials. Psoriatic pts received UST 45 or 90mg SC; Ph3 CD pts received one IV UST dose (130mg or ~6 mg/kg) then 90mg SC q8w or q12w. Permitted concurrent treatments differed by indication: PsO – none; PsA – methotrexate; CD - immunosuppressives & corticosteroids. All pts who received ≥1 dose of UST were included. Outcomes are presented as events per 100 PY. In the PBO-control period, 3636 pts received UST (1582 PsO, 692 PsA & 1362 CD). Treated pts with ≥1 reported event PBO vs UST in pooled indications (events/100 PY): AEs 556.1 vs 594.3; SAEs 19.5 vs16.4; infections 135.8 vs138.1; serious infections 2.9 vs 3.3; MACE 0.26 vs 0.60; malignancies 0.26 vs 0.12; deaths 0 vs 0.12. Through 1 year, 5884 pts received UST (3117 PsO, 1018 PsA, & 1749 CD) over 4521 PY. Rates of AEs, SAEs, & infections were similar between UST & PBO (Table) across all groups. Event rates in the combined CD studies were also similar between groups with more frequent overall AEs, & infections in CD pts. UST has a favorable safety profile in CD with one IV induction dose up to 6mg/kg & SC maintenance up to 90mg q8wks. Evaluation of the CD experience did not alter the safety profile of UST established in pts with psoriatic disease treated up to 5 years. Key safety events through 1yr aAssessed by investigator, b incl UST 1, 3, 4.5, or 6mg/kg IV; 130mg IV, SC 90mg; c1 MACE: subarachnoid hemorrhage due to aneurysm rupture; d4 events in 3 pts: 1 multiple myeloma, 1 adenocarcinoma & incidental carcinoid tumor; 1 prostate cancer Janssen Research & Development, LLC

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.
