Why real-world evidence matters

Randomised trials established the efficacy of rimegepant for the acute treatment of migraine, yet several questions that matter in the clinic fall outside the design of an RCT.

Will it work again?
Consistency of response from attack to attack → CONFIDENCE
What about difficult patients?
Chronic migraine, failed preventives, poor triptan response → GAINER
What if the dose is late?
Effect with «imperfect» timing of intake → GAINER
Will patients stay on therapy?
12-month persistence → US claims analysis

HeAD-US: gepants and triptans head-to-head

Digital platform Migraine Buddy, 1570 patients on monotherapy: triptans (n=1003) or gepants (n=567). The gepant group was «sicker» at baseline — more chronic migraine (38% vs 28%) and more preventive use (82% vs 71%) — the typical real-world pattern of gepants prescribed after triptan failure.

CONFIDENCE: «Will it work again?» — consistency of response

2169 attacks in 416 patients, 28 days of daily e-diaries (median 7 attacks per patient). A complex population: 84% on preventives (34% anti-CGRP mAbs and 34% botulinum toxin), 89% had previously discontinued at least one triptan.

About 2 in 3 patients had meaningful pain relief in ≥2 of their first 3 attacks; 74% were satisfied with treatment in ≥2 of 3 attacks. A predictable result simplifies treatment selection and supports adherence.

GAINER: difficult-to-treat patients of headache centres

16 headache centres n=103 CM — 24% of the sample mean 2.7 failed preventive classes 57% had absent or poor triptan response

The first real-world data on rimegepant in chronic migraine (44% of CM patients had medication overuse). Pain freedom at 2 hours was achieved by 44.7% — higher than in RCTs (19–21%), reflecting the open-label design and the population; pain relief by 70.9%.

Persistence: satisfaction converts into behaviour

Odds ratio of staying on therapy (rimegepant vs oral triptans), 95% CI.
The odds of staying on rimegepant were 2.7-fold higher than on oral triptans (OR 2.72; 95% CI 2.56–2.90); the result was consistent across all subgroups, including chronic migraine.

What the real-world data show

  • ✓
    High treatment satisfaction — 68–74% in CONFIDENCE; 71% vs 52% on triptans (NHWS); 7.1/10 in GAINER
  • ✓
    Consistent response from attack to attack — steady outcomes across attacks 1–4; 65% had relief in ≥2 of 3 attacks (CONFIDENCE)
  • ✓
    Recovery of functioning — functioning improved ≤2 h in 58% of attacks (CONFIDENCE); full recovery in 48% (GAINER)
  • ✓
    Sustained effect to 24 h — gepant advantage in 24-h relief: aOR 1.36 (HeAD-US); 64% pain-free at 24 h without rescue (GAINER)
  • ✓
    Value in patients with inadequate triptan response — 87% vs 62% — optimised treatment (Adelphi DSP); effect independent of prior triptan response (GAINER)
Real-world evidence complements the RCTs: a consistent, predictable response, clinically meaningful results in difficult-to-treat patients and with late dosing, high satisfaction and greater treatment persistence. The findings point to potential advantages of rimegepant in clinical practice.

Methodological notes

HeAD-US
Class-level comparison (gepants vs triptans), no per-molecule breakdown; cross-sectional self-report; likely channelling of «sicker» patients to gepants. The significant advantage was for 24-h relief only.
AAN 2025
Congress abstracts (Adelphi DSP, NHWS): descriptive analyses without full publications; wording — «patients reported higher satisfaction», no claims of superior efficacy.
CONFIDENCE
No comparator arm; experienced rimegepant users (responder selection likely); tolerability not systematically collected; descriptive statistics.
GAINER
n=103, no placebo control; the drug was not reimbursed — possible selection of difficult-to-treat headache-centre patients; the triptan comparison is a retrospective patient rating.
