188 SUNFISH 3-year efficacy and safety of risdiplam in types 2 and 3 SMA
Bibliographic record
Abstract
Risdiplam (EVRYSDI®) is an oral survival of motor neuron 2 (SMN2) premRNA splicing modifier approved by the EMA and MHRA for the treatment of patients aged ≥2 months, with a clinical diagnosis of Type 1, 2 or 3 spinal muscular atrophy (SMA) or 1–4 copies of SMN2. SUNFISH ( NCT02908685 ) is a two-part, randomised, placebocontrolled, double-blind study in a broad population of patients aged 2–25 years with Type 2/3 SMA. Part 2 assesses the efficacy and safety of the Part 1-selected dose of risdiplam versus placebo in Type 2 and non-ambulant Type 3 SMA. Participants were treated with risdiplam or placebo for 12 months; all participants then received risdiplam until Month 24. At Month 24, patients were offered the opportunity to enter the openlabel extension. The primary outcome of Part 2 – change from baseline to Month 12 in the 32-item Motor Function Measure total score in patients treated with risdiplam (n=120) versus placebo (n=60) – was met. Gains observed with risdiplam at Month 12 were maintained or improved upon at Month 24. At Month 24, there were no treatment-related safety findings leading to withdrawal. Here we present efficacy and safety data of patients who have received risdiplam for 36 months.

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.
