THUR 178 Infections during grade 3/4 lymphopenia with cladribine tablets
Bibliographic record
Abstract
Background In CLARITY, cladribine tablets 3.5 mg/kg (CT3.5) demonstrated efficacy in relapsing MS patients. The most common AE was lymphopenia, reflecting cladribine’s mode of action. Integrated safety analysis showed infection incidence was not higher in patients receiving CT3.5 vs placebo, bar a small increase of herpes zoster (HZV). Objective Post-hoc analysis examined infectious AEs occurring concurrently with Grade 3/4 lymphopenia (G3/4) in CT3.5 treated patients. Methods The AE profile for CT3.5 during the periods of G3/4 was analysed. Adjusted-AE incidences per 100 patient years (Adj-AE/100PY) were calculated in a cohort of patients receiving CT3.5 monotherapy in clinical trials. Results Data are presented as Adj-AE/100PY: G3/4 vs without G3/4. Adj-AE/100PY for any infections/infestations was 57.53 vs 24.50. Infections were similar between periods. ≥50% cases with G3/4 were easily-treatable upper- respiratory-tract infections (nasopharyngitis: 13.48 vs 5.24; upper-respiratory-tract infection: 9.67 vs 3.41; pharyngitis: 4.51 vs 0.73). HZV occurred in 4 patients with G3/4 (4.50 vs 0.73); cases were dermatomal and mild-to- moderate in severity. Single occurrences were reported for most infectious AEs. Opportunistic infections were single occurrences, not severe, serious or difficult-to-treat. Conclusions G3/4 increased frequency of infections but did not affect the type of infectious AEs in CT3.5 treated patients. HZV profile was uncomplicated, consistent with findings of previous analyses. Disclaimer http://medpub-poster.merckgroup.com/ABN2018DISC_Grade34.pdf

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.
