Longterm Therapeutic Response to Milnacipran Treatment for Fibromyalgia. A European 1-Year Extension Study Following a 3-Month Study
Bibliographic record
Abstract
OBJECTIVE: This double-blind, 1-year extension study investigated the longterm efficacy and safety of milnacipran 100, 150, and 200 mg/day in the treatment of fibromyalgia (FM) in completers of a 3-month European double-blind lead-in study of milnacipran 200 mg/day versus placebo. METHODS: A total of 468 patients with FM successfully completing the lead-in study were either blindly maintained on milnacipran 200 mg/day (MLN200:MLN200, n = 198) or (if previously receiving placebo) rerandomized to milnacipran 100 mg/day (PBO:MLN100, n = 91), 150 mg/day (PBO:MLN150, n = 92), or 200 mg/day (PBO:MLN200, n = 87) for an additional 12 months (including a 4-week dose escalation). The main efficacy endpoint was a 2-measure composite responder rate (relative to lead-in study baseline) incorporating the weekly-recall pain score recorded on a visual analog scale and the Patient Global Impression of Change score. A panel of other assessments including the Fibromyalgia Impact Questionnaire explored the multidimensional aspects of FM. Descriptive analyses using the last observation carried forward approach were performed. RESULTS: At the 1-year endpoint, the proportion of composite responders (relative to the lead-in study baseline) ranged from 27.5% (PBO:MLN100) to 35.9% (MLN200:MLN200), and had increased from the extension study baseline by 15.2% (PBO:MLN150) to 20.7% (PBO:MLN200 and MLN200:MLN200). At endpoint, an improvement from both baselines was shown in all groups on pain, fatigue, sleep, and quality of life measures. Up to 1 year, all doses of milnacipran were safe and well tolerated. The most common drug-related adverse events were hyperhidrosis and nausea. CONCLUSION: Over 1 year, milnacipran 100, 150, and 200 mg/day exhibited sustained and safe therapeutic effects on predominant symptoms of FM. Registered as trial no. NCT00757731.

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.
