Efficacy

The power to deliver rapid, long-lasting migraine pain freedom1

Viewing:

SYMBRAVO trials studied efficacy across the headache
phase for mild or moderate to severe migraine pain1

Earlier in the
headache phase when pain was mild

INTERCEPT TrialRandomized, double-blind, placebo-controlled trial in 302 patients with a history of migraine, with or without aura; single dose of SYMBRAVO taken1,2

Treated earlier in the headache phase when pain was mild1

  • All patients had a diagnosis of migraine with or without aura1

MOMENTUM TrialRandomized, double-blind, placebo-controlled trial in 1594 patients-SYMBRAVO (N=456), 10-mg rizatriptan (N=456), 20-mg meloxicam (N=455), placebo (N=227)­ with a history of migraine with or without aura; single dose of SYMBRAVO taken1,3

Treated later in the headache phase when pain was moderate to severe1

  • All patients had a diagnosis of migraine with or without aura1
  • All patients had a history of inadequate response to prior acute migraine medication3,a

As defined by Migraine Treatment Optimization Questionnaire (mTOQ-4), a questionnaire used to assess treatment efficacy. To be eligible for the MOMENTUM trial, patients needed mTOQ-4 scores of ≤7, indicating inadequate response to their prior migraine therapy over the preceding 4 weeks at screening. The maximum total score is 8, representing maximal treatment efficacy.3,4

SYMBRAVO was effective earlier in the headache phase when pain was still mild1

INTERCEPT was a randomized, double-blind, placebo-controlled trial in 302 patients with a history of migraine with or without aura, in which patients took a single dose of SYMBRAVO.1

INTERCEPT was a randomized, double-blind, placebo-controlled trial in 302 patients with a history of migraine, with or without aura, in which patients took a single dose of SYMBRAVO. Efficacy analysis was performed on the intent-to-treat (ITT) population, which included all patients who were randomized and had a qualifying migraine event (267 adult patients: SYMBRAVO, N=132; placebo, N=135). P-values were based on chi-squared test. Missing data were not imputed.1,2
b
Pain freedom was defined as a reduction to no headache pain.1
c
Patients who took rescue medication before hour 2 or who did not have an hour 2 value were treated as nonresponders.2
d
MBS freedom was defined as the absence of the self-identified MBS (ie, photophobia, phonophobia, or nausea).1
e
Patients who did not meet all the following requirements were considered nonresponders: pain intensity at and between hours 2 and 24 was 0; pain intensity was available for at least hour 12 or 16; and no rescue medication was used through hour 24.2
f
Rescue medication was only allowed 2 hours after initial treatment.1

Of patients in MOMENTUM who experienced migraine attacks when taking their previous migraine medications, the majority reported some combination of4,i:

  • NOT pain free within 2 hours
  • NOT pain free through 24 hours
  • NOT comfortable enough with their medication to plan daily activities
  • NOT in enough control of migraine to go about their daily activities

The clinical significance of mTOQ-4 has not been established.
