Brief summary

Medication overuse headache (MOH) is a type of headache caused by excessive use of acute headache or migraine medications (medications used to treat a headache or migraine once it begins). Treatment of MOH usually involves reducing the dose of or discontinuing acute medications. Eptinezumab is a medication used for the preventive treatment of migraine in adults. The main goals of this trial are to learn whether eptinezumab helps reduce the number of days with migraine, the number of days with headache, and acute medication use in adults who have migraine and MOH.

Detailed description

The total study duration from screening visit to safety follow-up visit is approximately 36 weeks and includes a screening period (4 weeks), a placebo-controlled period (12 weeks), an open-label period (12 weeks), and a safety follow-up period (8 weeks).

Open-label Period: Change From Baseline in Average Daily Pain Assessment Score at Weeks 13-16, 17-20, and 21-24

Daily Pain assessment data were collected in the headache eDiary via the question What was the worst pain intensity of this headache today?. The pain intensity assessment was collected on a 3-point scale: Mild (score = 1), Moderate (score = 2), and Severe (score = 3). For each day, the Daily Pain assessment score was derived by averaging the worst pain intensity over all headaches of that day. For days on which no headaches took place during the relevant period, the Daily Pain score was given as a score of 0. The average Daily Pain score was calculated using the Daily Pain assessments collected during Weeks 13-16, 17-20, and 21-24.

Open-label Period: Change From Baseline in mMIDAS Total Score at Week 24

The mMIDAS is a self-administered questionnaire that contains 7 questions about the headache a participant had in the previous month. The first 5 questions assess the impact of migraine on 3 domains of daily activity: 2 questions for paid work or schoolwork, 2 questions for household work, and 1 question for family, social and leisure activities. The 2 questions for each of the first two groups assess, respectively, the number of days off due to headache, and the number of days in which the productivity was reduced by half or more. mMIDAS total score was derived from the sum of the answers on the first 5 questions. Total score ranged from 0 (little/no disability) to 20 (severe disability) with higher scores indicating more severe disability.

Open-label Period: Change From Baseline in WPAI:M Sub-scores (Absenteeism, Presenteeism, Work Productivity Loss, Activity Impairment) at Week 24

The WPAI Questionnaire is a participant-reported instrument developed to measure the impact on work productivity and regular activities attributable to a specific health problem (migraine). Recall period is the past 7 days. It contains 6 items that measure: 1) employment status, 2) hours missed from work due to the specific health problem, 3) hours missed from work for other reasons, 4) hours actually worked, 5) degree health affected productivity while working, and 6) degree health affected productivity in regular unpaid activities. Four scores were calculated from the responses to these 6 items: absenteeism, presenteeism, work productivity loss, and activity impairment. Scores were calculated as impairment percentages (0-100%), with higher numbers indicating greater impairment and less productivity, that is, worse outcomes.

Open-label Period: MBS Score at Week 24

Participants were asked about their most bothersome symptom associated with their migraines during the Baseline Visit. Participants were asked to rate the improvement in this symptom from baseline on a 7-point scale (1 = very much improved; 2 = much improved; 3 = minimally improved; 4 = no change; 5 = minimally worse; 6 = much worse; 7 = very much worse) where a high score indicated worsening. Score ranges from 1 (Very Much Improved) to 7 (Very Much Worse). Lower scores indicate better health status. The MBS areas included: nausea, vomiting, sensitivity to light, sensitivity to sound, mental cloudiness, fatigue, pain with activity, mood changes, and other symptoms.

The PGIC is a single, participant-reported item reflecting the participant's impression of change in his/her disease status since the start of the study (that is, in relation to activity limitations, symptoms, emotions, and overall quality of life). Participants rated their impression of change in disease status on a 7-point scale (1 = very much improved; 2 = much improved; 3 = minimally improved; 4 = no change; 5 = minimally worse; 6 = much worse; 7 = very much worse) where a higher score indicated worsening. Score ranges from 1 (Very Much Improved) to 7 (Very Much Worse). Lower scores indicate better health status.

Open-label Period: TSQM-9 Score at Week 24

TSQM is a 14-item instrument consisting of four scales: effectiveness scale (questions 1 to 3), side effects scale (questions 4 to 8), convenience scale (questions 9 to 11) and global satisfaction scale (questions 12 to 14). In TSQM-9, the five items related to side effects of medication were not included. The scores were computed by adding items for each domain. The lowest possible score was subtracted from this composite score and divided by the greatest possible score minus the lowest possible score. This provided a transformed score between 0 and 1 that was then multiplied by 100. TSQM-9 domain scores range from 0 to 100 with higher scores representing higher satisfaction on that domain.

Placebo-controlled Period: Change From Baseline in Average Daily Pain Assessment Score at Weeks 1 to 2

Daily Pain assessment data were collected in the headache electronic diary (eDiary) via the question What was the worst pain intensity of this headache today?. The pain intensity assessment was collected on a 3-point scale: Mild (score = 1), Moderate (score = 2), and Severe (score = 3). For each day, the Daily Pain assessment score was derived by averaging the worst pain intensity over all headaches of that day. For days on which no headaches took place during the relevant period, the Daily Pain score was given as a score of 0. The average Daily Pain score was calculated using the Daily Pain assessments collected during Weeks 1-2.

Time frame: Baseline, Weeks 1 - 2

Placebo-controlled Period: Change From Baseline in Modified Migraine Disability Assessment (mMIDAS) Total Score at Weeks 4 and 12

The mMIDAS is a self-administered questionnaire that contains 7 questions about the headache a participant had in the previous month. The first 5 questions assess the impact of migraine on 3 domains of daily activity: 2 questions for paid work or schoolwork, 2 questions for household work, and 1 question for family, social and leisure activities. The 2 questions for each of the first two groups assess, respectively, the number of days off due to headache, and the number of days in which the productivity was reduced by half or more. mMIDAS total score was derived from the sum of the answers on the first 5 questions. Total score ranged from 0 (little/no disability) to 20 (severe disability) with higher scores indicating more severe disability.

Placebo-controlled Period: Change From Baseline in Work Productivity and Activity Impairment: Migraine (WPAI:M) Sub-scores (Absenteeism, Presenteeism, Work Productivity Loss, Activity Impairment) at Week 12

The WPAI Questionnaire is a participant-reported instrument developed to measure the impact on work productivity and regular activities attributable to a specific health problem (migraine). Recall period is the past 7 days. It contains 6 items that measure: 1) employment status, 2) hours missed from work due to the specific health problem, 3) hours missed from work for other reasons, 4) hours actually worked, 5) degree health affected productivity while working, and 6) degree health affected productivity in regular unpaid activities. Four scores were calculated from the responses to these 6 items: absenteeism, presenteeism, work productivity loss, and activity impairment. Scores were calculated as impairment percentages (0-100%), with higher numbers indicating greater impairment and less productivity, that is, worse outcomes.

Placebo-controlled Period: Most Bothersome Symptom (MBS) Score at Week 12

Participants were asked about their most bothersome symptom associated with their migraines during the Baseline Visit. Participants were asked to rate the improvement in this symptom from baseline on a 7-point scale (1 = very much improved; 2 = much improved; 3 = minimally improved; 4 = no change; 5 = minimally worse; 6 = much worse; 7 = very much worse) where a high score indicated worsening. Score ranges from 1 (Very Much Improved) to 7 (Very Much Worse). Lower scores indicate better health status. The MBS areas included: nausea, vomiting, sensitivity to light, sensitivity to sound, mental cloudiness, fatigue, pain with activity, mood changes, and other symptoms.

Time frame: Week 12

Population: FAS included all randomized participants who received an infusion of the IMP in the Placebo-controlled Period and had a valid Baseline assessment and at least 1 valid post-Baseline 4-week assessment of MMDs in Weeks 1-12.

Placebo-controlled Period: Treatment Satisfaction Questionnaire for Medicine - 9 Items (TSQM-9) Score at Weeks 4 and 12

TSQM is a 14-item instrument consisting of four scales: effectiveness scale (questions 1 to 3), side effects scale (questions 4 to 8), convenience scale (questions 9 to 11) and global satisfaction scale (questions 12 to 14). In TSQM-9, the five items related to side effects of medication were not included. The scores were computed by adding items for each domain. The lowest possible score was subtracted from this composite score and divided by the greatest possible score minus the lowest possible score. This provided a transformed score between 0 and 1 that was then multiplied by 100. TSQM-9 domain scores range from 0 to 100 with higher scores representing higher satisfaction on that domain.

Time frame: Weeks 4 and 12

Population: FAS included all randomized participants who received an infusion of the IMP in the Placebo-controlled Period and had a valid Baseline assessment and at least 1 valid post-Baseline 4-week assessment of MMDs in Weeks 1-12. 'Overall number of participants analyzed' = participants analyzed for this outcome measure. 'Number analyzed' = participants evaluable at specified category.
