Psilocybin for the Treatment of Migraine Headache

Phase 1
Completed
Conditions
Migraine Headache
Interventions
Registration Number
NCT03341689
Lead Sponsor
Yale University
Brief Summary

The purpose of this study is to investigate the effects of oral psilocybin in migraine headache. Subjects will each receive a dose of placebo and a dose of psilocybin approximately 14 days apart. Subjects will be randomized to the order of treatment and they will be randomized to receive either low or high dose psilocybin. Subjects will maintain a headache diary prior to, during, and after the treatments in order to document headache frequency and intensity, as well as associated symptoms. This preliminary study will inform on the basic effects of psilocybin in migraine headache and inform on the design of larger, more definitive studies.

Secondary Outcome Measures
NameTimeMethod
Change in the use of abortive/rescue medicationFrom two weeks before first session to two weeks after second session using a headache diary

number of days (number of days per week using a migraine abortive)

Quality of life using the Centers for Disease Control (CDC) Health-Related Quality of Life Scale: Healthy Days Symptoms ModuleFrom two weeks before first session to three months after second session using a headache diary

4 questions scored 0 to 30 each; higher numbers indicate worse quality of life.

(1) pain-related impairment, (2) mood symptoms, (3) anxiety symptoms, and (4) lack of sleep Percent change for each measure as well as total score (range 0 to 120) will be calculated.

Change in blood pressureMeasured during each test session prior to drug administration, every 15 minutes in the first hour, every 30 minutes in the second hour, and then hourly for 4 hours or until resolution of psychedelic effects (~6 hours post drug)

Maximum change in mean arterial blood pressure from baseline during each test day (mmHg)

Time to first migraine attackFrom the day of each session until two weeks after each test session

Measured in days

Change in heart rateMeasured during each test session prior to drug administration, every 15 min in the first hour, every 30 min in the second hour, and then hourly for 4 hours or until resolution of psychedelic effects (~6 hours post drug)

Maximum change from baseline during each test day (beats per minute)

Time to second migraine attackFrom the day of each session until two weeks after each test session

Measured in days

Psychedelic effects using the 5-Dimensional Altered States of Consciousness (5D-ASC) scaleTaken on each test day approximately 6 hours after drug administration

94 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 peripheral oxygenationMeasured during each test session prior to drug administration, every 15 min in the first hour, every 30 min in the second hour, and then hourly for 4 hours or until resolution of psychedelic effects (~6 hours post drug)
