A92 MULTIFACETED STRIDE II-BASED MONITORING FOR INFLAMMATORY BOWEL DISEASE ADVANCED THERAPY STARTS
Bibliographic record
Abstract
Abstract Background Inflammatory bowel disease (IBD) outreach monitoring has been shown to be cost-effective and reduce healthcare utilization. IBD STRIDE-II guidelines recommend monitoring patient-reported outcomes (PRO’s), biomarkers (e.g., fecal calprotectin (FCP), C-reactive protein (CRP)), and endoscopy to determine if patients achieve defined therapeutic targets. Previous monitoring in the literature has focused on PRO’s alone, which risks undertreating asymptomatic inflammation in spite of elevated flare and colorectal cancer risk. We designed a protocol to closely monitor biomarkers and PRO’s. Aims We aimed to assess STRIDE-II based clinical response and facilitate responsive disease management for new advanced therapy start patients. Methods Patients complete 24 weeks of outreach monitoring. PRO’s are obtained on days 0, 3, and 7, and every 2 weeks thereafter. Serum labs are collected at baseline and weeks 4, 8, 12, 16, and 24. FCP is collected at baseline and weeks 8, 16, and 24. Medication adherence is assessed at baseline and weeks 12 and 24. Endoscopy is booked 6-12 months from the start date. Treating gastroenterologists receive granular clinical reports summarizing results, the date of last IBD review, and last flare. Results 75 protocol patients on the following therapies: ustekinumab (n = 31), risankizumab (n = 17), tofacitinib (n = 14), upadacitinib (n = 10), vedolizumab (n = 2), and infliximab (n = 1) were monitored in our protocol so far. 51 patients (68.0%) had failed 1+ prior advanced therapies and 13 (17.3%) had prior IBD surgery. 7 (9.3%) were switched from their initial agent before 24 weeks due to lack of response. 1 (1.3%) had an adverse drug event. 64 patients (85.3%) complied with all FCP collections and 73 (97.3%) completed 95+% of PRO’s. Per STRIDE-II definitions, 47 patients (62.7%) demonstrated clinical response during the protocol and 25 (33.3%) achieved remission by 24 weeks. 15 (20.0%) received steroid courses, 9 (12.0%) presented to an emergency department, and 5 (6.7%) were hospitalized for IBD during monitoring. Conclusions Our proactive monitoring protocol provided granular real-world clinical response data to treating physicians. Patients were highly compliant with serial PRO, FCP, and serum labs collection. The protocol facilitates responsive disease management and may lead to treatment-specific monitoring recommendations. In future, we will compare protocol patients to standard of care managed patients to learn if the protocol reduces healthcare utilization and improves patient outcomes and quality of life.

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.
