Abstract

BACKGROUND: Levomilnacipran extended release (ER) is a serotonin and norepinephrine reuptake inhibitor approved for major depressive disorder (MDD) in adults. This study was designed to evaluate relapse prevention with levomilnacipran ER in patients with MDD. METHODS: Patients (≥18 years) with MDD (N = 644) received 20 weeks of open-label treatment with levomilnacipran ER 40, 80, or 120 mg/d (8 weeks flexible dosing; 12 weeks fixed dosing). Patients with a Montgomery-Åsberg Depression Rating Scale (MADRS) total score ≤12 from the end of week 8 to week 20 were randomized to 26 weeks of double-blind treatment with levomilnacipran ER (same dosage; n = 165) or placebo (n = 159). The primary efficacy endpoint was time to relapse, defined as insufficient therapeutic response (≥2-point increase from randomization in Clinical Global Impression of Severity score, risk of suicide, need for hospitalization due to worsening of depression, or need for alternative antidepressant treatment as determined by the investigator) or an MADRS total score ≥18 at 2 consecutive visits. RESULTS: In the double-blind intent-to-treat population, levomilnacipran ER-treated patients had a significantly longer time to relapse compared with placebo (hazard ratio = 0.56; 95% CI, 0.33-0.92; P = 0.0212). Crude relapse rates were 14.5% (levomilnacipran ER) and 24.5% (placebo). Double-blind treatment-emergent adverse events (AEs) were reported for 58.8% and 56.0% of levomilnacipran ER and placebo patients, respectively; 3.0% and 1.3% discontinued due to AEs, and 1.2% and 0.6% had serious AEs, respectively. CONCLUSION: Levomilnacipran ER (40-120 mg/d) was effective in preventing relapse in patients with MDD. Safety and tolerability results were consistent with levomilnacipran ER acute studies.

TL;DR

In adults with MDD who responded to 20 weeks of open-label levomilnacipran ER, continuing levomilnacipran ER for 26 weeks significantly prolonged time to relapse versus placebo. Safety and tolerability were consistent with levomilnacipran ER acute studies.

Key findings

  • Time to relapse was significantly longer with levomilnacipran ER than placebo: HR = 0.56 (95% CI, 0.33–0.92; P = 0.0212). Crude relapse rates were 14.5% (24/165) with levomilnacipran ER and 24.5% (39/159) with placebo.
  • The most common relapse reason was insufficient therapeutic response, defined as ≥2-point increase from randomization in CGI-S score: 70.8% (17/24) in the levomilnacipran ER group and 79.5% (31/39) in the placebo group. No patients relapsed due to suicide risk or hospitalization for worsening depression.
  • Double-blind treatment-emergent AEs occurred in 58.8% of levomilnacipran ER patients and 56.0% of placebo patients; discontinuations due to AEs were 3.0% vs 1.3%, and serious AEs were 1.2% vs 0.6%, respectively. Nausea was the only TEAE reported in ≥5% of levomilnacipran ER patients and at twice the placebo rate (7.9% vs 3.1%).
  • Additional efficacy measures worsened more in the placebo group than in the levomilnacipran ER group at the end of double-blind treatment, including MADRS total score (LS mean change +5.3 vs +3.0; LSMD −2.3 [95% CI, −4.3 to −0.4]) and CGI-S, SDS total, and SDS subscale scores (P < 0.05 for all LOCF outcomes).

Methods

  • Multicenter, randomized, double-blind, placebo-controlled relapse-prevention study (NCT02288325) conducted at 44 US centers from 2014 to 2016. The study was up to 53 weeks: 8-week open-label flexible-dose run-in, 12-week open-label fixed-dose stabilization, 26-week double-blind treatment, and down-taper.
  • Patients were adults ≥18 to ≤70 years with DSM-5 MDD, ongoing major depressive episode, ≥3 lifetime depressive episodes, and MADRS total score ≥26. A total of 644 entered open-label treatment; 324 were randomized to double-blind treatment (165 levomilnacipran ER, 159 placebo).
  • Primary endpoint was time to first relapse, analyzed using the log-rank test with Cox proportional hazards model for HR and 95% CI, and Kaplan–Meier curves. Additional efficacy used ANCOVA with LOCF; safety was summarized descriptively.

Limitations

  • The authors state that the long open-label treatment period, including the 12-week stabilization phase, may have limited the number of observed relapse events; the open-label initial phases could be considered a limitation; the double-blind phase had no active comparator; because doses were optimized for each patient, no conclusions can be drawn about specific doses; strict eligibility criteria limit generalizability; and the MADRS ≥18 relapse cutoff may have lacked sensitivity given the low mean MADRS baseline score at randomization (∼5).
  • The authors also note the randomized withdrawal design raises the possibility that placebo-arm relapses could reflect withdrawal symptoms rather than true relapse, but they report low and similar early relapse rates and a post hoc analysis censoring relapses during the first 28 days that maintained the significant levomilnacipran ER advantage.
  • Evident from the text: the double-blind phase was 26 weeks, and the study enrolled a selected population that had already responded to and tolerated open-label levomilnacipran ER, which may limit applicability to broader MDD populations.

  • The paper relies on this without support.

    Withdrawal symptoms from levomilnacipran ER, if they occur, would be expected during the first few weeks after randomization.

    “an excess of relapse events would be expected in the placebo arm during the first few weeks of treatment when withdrawal symptoms are likely to occur.”

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • One double-blind randomized placebo-controlled trial reported that levomilnacipran outperformed placebo in relapse rate at study-endpoint, while another did not report the statistical result; one trial investigating milnacipran also did not report statistical results.

    “One DBRPCT reported that levomilnacipran outperformed placebo in terms of relapse rate at the study-endpoint [22], while another DBRPCT did not report the statistical result of the outcome [49]; one trial investigating milnacipran also did not report the statistical results [47].”

  • 20 articles define relapse with psychometric measures (Hamilton Depression Rating Scale, Beck Depression Inventory, Montgomery-Asberg Depression Rating Scale, Goldberg Anxiety and Depression Scale, Clinical Global Impression).

    “20 do so with psychometric measures (Hamilton Depression Rating Scale, Beck Depression Inventory, Montgomery-Asberg Depression Rating Scale, Goldberg Anxiety and Depression Scale, Clinical Global Impression) (4, 7, 9, 13–18, 33, 34, 42–49)”
  • The second most used scale is the Montgomery-Asberg Depression Rating Scale (MADRS), with 7 studies establishing the definition of relapse based on it, with varying criteria: 15+, 18+, 21 or 50% increase, and >=22 for 2 consecutive weeks.

    “The second most used scale is the Montgomery-Asberg Depression Rating Scale (MADRS), with 7 studies establishing the definition of relapse based on it, although again the criteria vary; for Verwijk et al. (16) and van Diermen et al. (46) a score of 15 or more would be sufficient, for Durgam et al. (15), 18 or more”
  • 4 studies use the Clinical Global Impression (CGI-S), 2 use the Beck's Depression Inventory, and 1 uses the Goldberg Anxiety and Depression Scale (GADS).

    “Finally, 4 studies use the Clinical Global Impression (CGI-S) (15, 33, 43, 48), 2 use the Beck`s Depression Inventory (4, 9) and 1 uses the Goldberg Anxiety and Depression Scale (GADS) (20).”
  • 40 articles define relapse based on administrative criteria.

    “and 40 define it based on what we will establish as administrative criteria (1, 4, 7, 9, 11–13, 15–29, 33, 34, 38, 39, 42–50, 52–55).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
