Migraine Headache

Keywords

psilocybin, inflammation, calcitonin gene-related peptide (CGRP), pituitary adenylate cyclase-activating peptide (PACAP)

Brief summary

In seeking to understand the capacity for psilocybin to reduce migraine headache burden, this study will investigate single and repeated dosing of psilocybin up to two doses. In seeking to identify an underlying mechanism in psilocybin's effects, neuroinflammatory markers for migraine headache will be measured.

Detailed description

Migraine headache is a common medical condition and a top cause of disability worldwide. Treatment options for migraine headache are many and varied, though an approximated 10% of migraineurs is refractory to medication and thus, there is a need to develop alternative treatments. There is anecdotal evidence supporting lasting therapeutic effects after limited dosing of psilocybin and related compounds in headache disorders. The cause of this unique effect remains unknown, though the drug class has demonstrable anti-inflammatory activity, a biological process relevant to migraine and other headache disorders. In seeking to understand the capacity for psilocybin to reduce migraine headache burden, this study will investigate single and repeated dosing of psilocybin up to two doses. In seeking to identify an underlying mechanism in psilocybin's effects, neuroinflammatory markers for migraine headache will be measured. The results from this study will serve in the development of larger investigations seeking to understand the effects of psilocybin and related compounds in headache disorders.

Design outcomes

Primary

MeasureTime frameDescription
Change in migraine attack frequencyFrom two weeks before the first session to two months after second session using a headache diaryAverage number (number per week)
Change in pain intensity of migraine attacksFrom two weeks before the first session to two months after second session using a headache diaryAverage pain intensity (4-tiered pain score; 0=none, 1=mild, 2=moderate, 3=severe)
Change in duration of migraine attacksFrom two weeks before the first session to two months after second session using a headache diaryAverage duration (measured in hours)
Change in intensity of photophobia (light sensitivity)From two weeks before the first session to two months after second session using a headache diaryAverage intensity (4-tiered pain score; 0=none, 1=mild, 2=moderate, 3=severe)
Change in intensity of phonophobia (noise sensitivity)From two weeks before the first session to two months after second session using a headache diaryAverage intensity (4-tiered pain score; 0=none, 1=mild, 2=moderate, 3=severe)
Average intensity of nausea/vomitingFrom two weeks before the first session to two months after second session using a headache diaryAverage intensity (4-tiered pain score; 0=none, 1=mild, 2=moderate, 3=severe)
Change in functional disabilityFrom two weeks before the first session to two months after second session using a headache diaryAverage disability (4-tiered pain score; 0=none, 1=mild, 2=moderate, 3=severe)

Secondary

MeasureTime frameDescription
Change in blood pressure- DiastolicStarting on the first test day until the second test day approximately one week later; measured both test sessions before drug administration, every 30 min in the first hour, then hourly for 4 hours or until resolution of drug effects (~6hrs after drug)Maximum change from baseline during each test day (mm Hg)
Change in heart rateStarting on the first test day until the second test day approximately one week later; measured both test sessions before drug administration, every 30 min in the first hour, then hourly for 4 hours or until resolution of drug effects (~6hrs after drug)Maximum change from baseline during each test day (beats per minute)
Use of abortive/rescue medicationFrom two weeks before the first session to two months after second session using a headache diarynumber of times per week
Change in pituitary adenylate cyclase-activating peptide (PACAP) levelsApproximately 3 months; measured at screening, on both test days (0, 2, and 4 hours after drug administration), and follow-up (~2 months after second test day)Change in peripheral neuropeptide levels
Change in peripheral oxygenationStarting on the first test day until the second test day approximately one week later; measured both test sessions before drug administration, every 30 min in the first hour, then hourly for 4 hours or until resolution of drug effects (~6hrs after drug)Maximum change from baseline during each test day (SpO2)
Time to first migraine attackFrom the second session until two months after second session using a headache diaryMeasured in days
Migraine attack-free timeFrom two weeks before the first session to two months after second session using a headache diaryNumber of 24-hour days (may be non-consecutive)
Quality of life using the Centers for Disease Control (CDC) Health-Related Quality of Life Scale: Healthy Days Symptoms ModuleFrom two weeks before the first session to two months after second session using a headache diary4 questions scored 0 to 30 each; higher numbers indicate worse quality of life. (1) pain-related impairment, (2) mood symptoms, (3) anxiety symptoms, (4) lack of sleep. Percent change for each measure as well as total score (range 0 to 120) will be calculated
Change in peripheral calcitonin gene-related peptide (CGRP) levelsApproximately 3 months; measured at screening, on both test days (0, 2, and 4 hours after drug administration), and follow-up (~2 months after second test day)Change in peripheral neuropeptide levels
Psychedelic effects using the 5-Dimensional Altered States of Consciousness (5D-ASC) scaleStarting on the first test day until the second test day approximately one week later; taken both test days approximately 6 hours after drug administration94 questions scored 0 to 100 each; higher numbers indicate greater psychedelic effects. Questions address 5 dimensions: (1) Oceanic Boundlessness (score range 0-2700), (2) Dread of Ego Dissolution (score range 0-2100), (3) Visionary Restructuralization (score range 0-1800), (4) Auditory Alterations (score range 0-1600), and (5) Vigilance Reduction (score range 0-1200). Score for each dimension as well as total score (range 0 to 9400) will be measured.
Change in blood pressure- SystolicStarting on the first test day until the second test day approximately one week later; measured both test sessions before drug administration, every 30 min in the first hour, then hourly for 4 hours or until resolution of drug effects (~6hrs after drug)Maximum change from baseline during each test day (mm Hg)
