Formulary Management of Targeted Immune Modulators in Ulcerative Colitis
Bibliographic record
Abstract
Health Canada has approved 7 targeted immune modulators for the treatment of adults with moderate to severe ulcerative colitis, which include 5 biologics (adalimumab, infliximab, golimumab, ustekinumab, and vedolizumab) and 2 small molecules (tofacitinib and ozanimod). Biosimilars for adalimumab and infliximab and generics for tofacitinib are currently available in the Canadian market; however, although their patent protection has expired, there are no biosimilars for golimumab and ustekinumab. All targeted immune modulators have undergone pan-Canadian Pharmaceutical Alliance negotiations and concluded with a Letter of Intent except for ustekinumab, which is the only targeted immune modulator not included on any public formularies for ulcerative colitis. Coverage is consistent across all drug plans except for golimumab and tofacitinib, which is not covered by all jurisdictions for ulcerative colitis. Most public drug plans have implemented or have announced a biosimilar policy to promote the use of biosimilars over originator biologics. The listing status for targeted immune modulators in ulcerative colitis is similar across public drug plans; however, there is heterogeneity in criteria requirements for prior treatments and diagnosis definitions. Considering these factors and the emergence of new data, it would be important to reassess these drugs and evaluate their place in therapy. Further research, such as horizon scanning, utilization analyses, and long-term effectiveness and safety studies, is warranted for targeted immune modulators to ensure the appropriate use of these drugs in the treatment of moderate to severe ulcerative colitis.

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.
