Persistence of treatment effect of idebenone in Leber's Hereditary Optic Neuropathy
Bibliographic record
Abstract
Abstract Purpose To establish the long term benefit of oral idebenone 900mg/day in the treatment of Leber's Hereditary Optic Neuropathy (LHON). Methods Patients who participated in a 24‐week, multi‐centre (3 sites), double‐masked, randomized, placebo controlled trial (RHODOS) were re‐assessed at a single visit by means of Visual Acuity (VA) using ETDRS charts. Results Eighty‐five patients were enrolled in the RHODOS study: 55 treated with idebenone (900mg/day) and 30 with placebo. At the end of the 24 week treatment period, the VA for patients randomized to placebo deteriorated. In contrast, in patients treated with 900mg/day idebenone, VA was preserved. In addition, in severely affected patients with off‐chart vision at Baseline, only idebenone treated patients improved sufficiently to read at least 1 full line on the ETDRS chart (Klopstock et al., 2011). VA was repeated at a follow‐up visit conducted 2.5 years (median) after treatment discontinuation. The difference in VA between placebo and idebenone treated patients was maintained. Specifically, in patients who during RHODOS received idebenone and who on average were protected from vision loss, VA did not deteriorate upon discontinuation of treatment. Conclusion These findings support the original conclusion that in selected patients with LHON, idebenone has significant therapeutic potential in preventing further vision loss and facilitating vision recovery.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
