Voclosporin: a novel calcineurin inhibitor with no impact on mycophenolic acid levels in patients with SLE
Bibliographic record
Abstract
BACKGROUND: An open-label phase 1 study was conducted to evaluate the effect of voclosporin following dosing with mycophenolate mofetil (MMF) on blood levels of mycophenolic acid (MPA, the active moiety of MMF) and MPA glucuronide (MPAG, the pharmacologically inactive metabolite of MMF) in subjects with systemic lupus erythematosus (SLE) and to assess the safety and tolerability of the combination. METHODS: MMF was orally administered at a dose of 1 g twice a day for at least 28 days prior to the study and continued at the same dose throughout the study. Voclosporin was orally administered at a dose of 23.7 mg twice a day for 7 consecutive days (Days 1-7), starting on the evening of Day 1 and ending with the morning dose on Day 7. Dense pharmacokinetic blood samples were collected pre-dose in the morning and from 0.25 to 12 h after the morning doses. Analyses were derived by non-compartmental methods. RESULTS: In 24 patients, MPA exposure [maximum serum concentration (Cmax) and area under the concentration curve from time 0 to 12 h (AUC0-12)] was similar in the presence and absence of voclosporin, with treatment ratios of 0.94 and 1.09, respectively [Cmax 16.5 μg/mL (Day 1) versus 15.8 (Day 7), AUC0-12 39.1 μg/h/mL (Day 1) versus 40.8 (Day 7)]. MPAG exposure showed a small increase in the presence of voclosporin (12% for Cmax and 27% for AUC0-12). Combination therapy was well tolerated. CONCLUSIONS: There is no clinically meaningful interaction between voclosporin and MMF. As changes in exposure to MPA may affect efficacy and safety, these data confirm that voclosporin and MMF can be administered concomitantly without the need for dose adjustment.

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.
