Elinzanetant in postmenopausal women with sleep disturbance: results from the randomized, phase II NIRVANA study.
Trial report in Sleep, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
STUDY
objectivesMenopausal sleep disturbances can negatively impact quality of life. Elinzanetant, a dual neurokinin (NK)-1/NK-3 receptor antagonist, reduced self-reported sleep disturbance in postmenopausal women with moderate-to-severe vasomotor symptoms (VMS) in Phase III OASIS trials. NIRVANA explored elinzanetant's effect on multimodal measures of objective and subjective sleep disturbance in postmenopausal women. MATERIALS AND
methodsPostmenopausal women (N = 110; 40-65 years) with moderate-to-severe VMS (≥20/week) and sleep disturbance (polysomnography [PSG] wakefulness after sleep onset [WASO] ≥30 min) were randomized 1:1 to receive elinzanetant 120 mg or placebo for 12 weeks. Sleep disturbance was assessed using PSG; daily Sleep Diary; and nightly contactless home-monitoring (Sleepiz One+ subgroup). The effect of elinzanetant versus placebo was analyzed using mixed-model repeated measures.
resultsElinzanetant was estimated to reduce PSG WASO at Week 4 versus placebo (least square [LS]-mean difference = -22.50 minutes, 90% CI: -35.47, -9.52). Minimal group differences between treatment arms were estimated at Week 12 for PSG WASO (LS-mean difference = -0.94 minutes, 90% CI: -13.96, 12.09). When including all available PSG data across the 12-week period, post hoc random coefficient modeling indicated treatment effects favoring elinzanetant for WASO, total sleep time, sleep efficiency, latency to persistent sleep, number of awakenings, arousal index, and % Stage N2 sleep. Treatment effects on WASO and awakenings favoring elinzanetant were observed with Sleepiz One+ and Sleep Diary across 12 weeks.
conclusionIn this sleep-focused study, elinzanetant reduced WASO at Week 4 and led to estimated improvements in sleep continuity over 12 weeks, supported by multimodal subjective and objective sleep outcomes.
