Treatment guidelines recommend preventive treatments for people with frequent and
disabling headaches
Only one-third of people with migraine
who meet guidelines for preventive treatments
receive them1
Of those who start preventive treatment, 80% lapse over the
course of 1 year2
• Why aren’t preventive treatments being more widely utilized?
• How can we optimize the appropriate use of preventive treatments?

Migraine Frequency Exists on a Spectrum
6
<15 headache days per month
can be classified as episodic migraine2
≥15 headache days per month for >3 months can be
classified as chronic migraine2
• One-third of people with migraine have headache on ≥4 days per month, and 6% have headache on 15 or more days per month1
• Traditional criteria for preventive treatment are defined in part by headache days

Migraine Is Usually Associated With Severe Impairment or Need for Bed Rest
Migraine-related impairment was common in the American Migraine Prevalence and Prevention (AMPP) study of >18,000 individuals with migraine.1
Respondents were asked how they are “usually affected by severe headaches” with the following response options:2
• Able to work/function normally
• Working ability or activity impaired to some degree
• Working ability or activity severely impaired
• Bed rest required

Migraine Prevention Is Underused
17
~39%
were candidates for or should be considered for prophylactic treatment1
Data from the AMPP study suggest that approximately two-thirds ofindividuals with migraine who qualify for prophylaxis do not receive it2
The AMPP study surveyed 18,968 individuals with migraine and found that
~29%
had received prophylactic medication for migraine in the
past but discontinued treatment2
~12%
were current users of prophylactic medication for the treatment of migraine1
*Oral prophylactic medications analyzed in this retrospective study were limited to specific antidepressants, β-blockers, and anticonvulsants.
Adherence rates were reported as the proportion of patients with a proportion of days covered ≥80%.

Patient-Reported Reasons for Discontinuation of Prophylactic Medication
4. High discontinuation rates on current therapies may reflect unmet and inadequately managed patient expectations.
Defining Success in Migraine Prevention
20
1. Standard definition of success is a 50% headache response rate (50% reduction in migraine days from baseline to weeks 9 to 12 or later).
2. This definition is predicated on the art of the possible or on what available treatments deliver.
3. Patients would prefer greater reductions in migraine days that would be achieved more quickly.

40%
More than 40% of patients receiving therapy still experience at least one migraine-related issue, including headache-related disability, treatment dissatisfaction, and/or excessive opioid use2
13%
Up to 13% of patients with migraine receiving acute or preventive therapy still have at least 1 emergency department visit a year3
80%Approximately 80% of patients discontinue oral preventive therapy after 1 year of treatment1
RCTs=randomized, controlled trials.

All Approved Oral Drugs Share Similar Efficacy to Prevent Migraine
29
• Topiramate and antidepressants result in more adverse events
• No significant differences in treatment discontinuation due to adverse events between labeled drugs
• Angiotensin-converting enzyme inhibitors and beta blockers most tolerable and effective
• Long-term evidence is lacking (>3-month duration)
215 publications of RCTs provided mostly low-strength evidence because of the risk of bias and imprecision
• Metoprolol (4 RCTs)
• Atenolol (1 RCT)
• Nadolol (1 RCT)
• Captopril (1 RCT)
• Lisinopril (1 RCT)
• Candesartan (2 RCTs)

Lasmiditan - 5-HT1F AgonistPhase 3 Trials for Acute Treatment of Episodic Migraine
• 2-Hour Pain Freedom:
100 mg- 28.2-31.4%
200 mg- 32.4-38.8%
Placebo- 15.3%-21.3%
• Both doses also eliminated the Most Bothersome
Symptom (MBS), chosen by the patient from
nausea, photophobia, or phonophobia at 2 hours
• Adverse events in the Phase 3 RCTs:
Dizziness + vertigo =100 mg average 15.5% 200 mg average 16.8%
Somnolence + fatigue + lethargy =100 mg average 10.4%
200 mg average 12%
• For comparison, rizatriptan 10 mg prescribing information:
Dizziness 20% greater than lasmiditan
Somnolence + fatigue 15% greater than lasmiditan
44
Conclusions for lasmiditan acute treatment:
• Efficacy and side effects similar to rizatriptan
• Central adverse events probably due to central 5-HT1F activity and likely no vasoconstrictive effects

Gepants - Small Molecule CGRP Receptor Antagonists
Acute Treatment of Episodic Migraine • 6 gepants effective in acute migraine treatment: olcegepant, BI 44370 TA, telcagepant, MK-3207, rimegepant, and ubrogepant
• BI 44370 TA, telcagepant, and MK-3207 all reportedly liver toxic
• Efficacy: Ubrogepant Phase 3 acute treatment of episodic migraine: • 2-hour pain freedom: 50 mg 19.2%; 100 mg 21.2%; placebo 11.8%; Also relieved 2-hour MBS
• Efficacy: Rimegepant Phase 3 acute treatment of episodic migraine: • 2-hour pain freedom: 75 mg 19.2-19.6%; placebo 12%-14.2%; also relieved 2-hour MBS
• Adverse events1. Liver, Ubrogepant: 6 cases with ALT >3x ULN, one of which was 10X ULN; 1 case with placebo >3x ULN; Rimegepant: one case
each from active and placebo with >3x ULN
2. Tolerability, Ubrogepant: nausea, somnolence, dry mouth in <5% of patients; Rimegepant: nausea in <2% of patients
45
Preventive Treatment of Episodic Migraine
• Telcagepant had liver toxicity when given daily
• Atogepant vs placebo positive phase 2 for migraine prevention, no liver signal; Rimegepant to be tested
Conclusions for gepants acute treatment:
• Efficacy and side effects similar to naratriptan
• Tolerability is excellent
• Liver safety will still need to be explored
• Prevents vasodilation; no expectation of vasoconstriction

MABs to CGRP or the CGRP Receptor
• Physiological differences from presently available options
• MABs are big molecules that do not cross the blood brain barrier
• Peripheral, not central, mechanism of action
• MABs are eliminated by the reticuloendothelial system
• No hepatic, renal toxicity
• Clinical differences from presently available options
• Work to prevent episodic and chronic migraine, and medication-overuse headache
• Have quick onset, separating from placebo within 1 week
• Clinically meaningful response by 1 month
• Have favorable responder rates for ≥50%, 75%, and 100%
• Have safety and tolerability similar to placebo

Clinical Utility of the 4 MABs
• All data announced to date for EM and CM have shown a reduction in mean monthly migraine days (MMDs) with a magnitude of 1-3 days drop over placebo
• Using MMDs is necessary from a regulatory standpoint, but not clinically useful endpoint• More useful are certain secondary endpoints, such as responder rates
• Erenumab in CM prevention showed a 6.7-day reduction in MMDs in the pivotal trial, which would represent 79 fewer migraine days/year1; for eptinezumab, an 8-day reduction from baseline would be 96 fewer migraine days per year
• The ≥50% responder rates (secondary endpoints) in the galcanezumab EM registration studies were ≥50%,in the eptinezumab CM study 61%, and the ≥75% responder rates for both were about 1/3 of patients2,3
• Erenumab 140 mg worked in patients who had failed 2-4 preventive medications in a prospective randomized placebo-controlled trial4
49
Practical dosing
• Erenumab – 70 mg or 140 mg SQ monthly
• Fremanezumab – 225 mg SQ monthly or 775 mg SQ quarterly
• Galcanezumab – 240 mg SQ month 1, then 120 mg SQ monthly

Noninvasive Vagal Nerve Stimulator (nVNS, gammaCore)
• Handheld, patient-controlled device, which preferentially activates afferent A and large B fibers, not C or efferent pathways that mediate bradycardia and bronchoconstriction1
• Inhibits CSD2 and central trigeminovascular and thalamocortical pathways3,4
• 2 RCTs showed effectiveness in terminating attacks of episodic cluster headache, but not chronic cluster headache5,6
• 2 RCTs failed primary endpoints in prevention and acute treatment of migraine, but showed suggestive secondary endpoints7,8
• FDA-approved as nonsignificant risk device for acute treatment of episodic cluster headache attacks and acute treatment of migraine
• $575/month for loaded stimulation package

Remote Nonpainful Electrical Upper Arm Stimulation(Nerivio Migra)
• Prospective, double-blinded, randomized, crossover, sham-controlled trial in acute migraine
• Participants with migraine applied electrical patch to upper arm soon after attack onset for 20 minutes, at various pulse widths, for up to 20 attacks
• 50% pain reduction for 64% of participants based on best of 3-pulse width stimuli per individual vs 26% sham, N=71 patients, 299 treatments
• Second study underway in US
