Abstract
Background: RPC1063 is an oral, selective sphingosine 1-phosphate 1 receptor modulator in clinical development for the treatment of relapsing multiple sclerosis (RMS). Objectives: Demonstrate the superior efficacy of low (LD, 0.5 mg) and high (HD, 1.0 mg) dose RPC1063 vs. placebo (PBO), and characterize the safety of RPC1063 in patients with RMS. Methods: RADIANCE is an international, combined Phase 2/3 trial. In the 24-week, Phase 2 portion, 258 patients were randomized (1:1:1) to PBO (n=88), LD (n=87) or HD (n=83). The primary endpoint was the cumulative number of total gadoliniumenhancing (GdE) lesions on MRI at Wks 12, 16, 20 and 24. Key secondary endpoints included number of GdE lesions at Wk 24, cumulative number of new/enlarging T2 lesions from Wks 12-24, and annualized relapse rate (ARR). Safety was assessed using vital signs, labs, ECG, Holter monitoring, PFT, OCT and adverse events (AEs). Patients were titrated to their assigned dose over one week to mitigate first dose heart rate effects. Results: 98% of patients completed the trial. Cumulative total Wk 12-24 GdE lesions was reduced 86% in both RPC1063 arms vs. PBO (mean SD: PBO 11.1 29.9, LD 1.5 3.7, HD 1.5 3.4, both p< 0.0001). Numbers of GdE lesions at Wk 24 were significantly reduced 91 and 94% (PBO 3.2 9.8, LD 0.3 0.9, HD 0.2 0.6, both p< 0.0001) and cumulative Wks 12-24 new/enlarging T2 lesions 84 and 91% (PBO 9.0 20.9, LD 1.4 3.2, HD 0.8 1.9, both p< 0.0001). A favorable trend in ARR reduction was observed vs. PBO (LD: 31%, p=0.27; HD: 53%, p=0.053).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
