Outcome Measures
Primary Outcome Measures
- Change from baseline in monthly migraine days (MMD) [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The monthly migraine days (MMD) is assessed by eDiary, completed every day by the participant, to evaluate the efficacy of Dysport® compared to placebo.
Secondary Outcome Measures
- Change from baseline in MMD of ≥50% [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The monthly migraine days (MMD) is assessed by a daily eDiary.
- Change from baseline in MMD of ≥75% [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The monthly migraine days (MMD) is assessed by a daily eDiary.
- Cumulative number of MMD [From Day 1 to Week 24] The cumulative number of monthly migraine days (MMD) is assessed by a daily eDiary.
- Change from baseline in MMD of moderate or severe intensity [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The intensity of MMD is assessed by a daily eDiary.
- Change from baseline in monthly headache days (MHD) of moderate or severe intensity [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The intensity of monthly headache days (MHD) is assessed by a daily eDiary.
- Change from baseline in MHD of moderate or severe intensity of ≥50% [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The intensity of monthly headache days (MHD) is assessed by a daily eDiary.
- Change from baseline in MHD of moderate or severe intensity of ≥75% [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The intensity of monthly headache days (MHD) is assessed by a daily eDiary.
- Cumulative number of MHD of moderate or severe intensity [From Day 1 to Week 24] The cumulative number of monthly headache days (MHD) is assessed by a daily eDiary.
- Change from baseline in the number of days per month of acute migraine medication intake [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The acute migraine medication intake will be recorded in the daily eDiary Acute migraine medication is defined as triptan, ergotamine, gepant, or ditan
- Headache medication overuser (yes, no) [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The headache medication overuse will be assessed by a concomitant medication log completed at each visit and acute medication taken to treat acute attack will be recorded in the daily eDiary. The headache medication overuse is defined as a participant with ≥10 days/month if ergotamine, triptan, gepant, ditan, opioid or combination analgesic, or ≥15 days/month if non-opioid analgesic (such as paracetamol, aspirin, NSAID)
- Use of acute migraine medication (yes or no) [Every 4 weeks from Week 4 (Weeks 1-4) to Week 24 (Weeks 21-24)] The use of acute migraine medication will be recorded in the daily eDiary.
- Patient's Global Impression of Change (PGIC) score [At Weeek 12 and Week 24] The PGIC will be assessed by a questionnaire (7-point scale, score of 1 indicates very much improved and score of 7 indicates very much worse)
- Change from baseline of ≥1 and ≥2 grades in PGIC score [At Weeek 12 and Week 24] The PGIC will be assessed by a questionnaire (7-point scale, score of 1 indicates very much improved and score of 7 indicates very much worse)
- Change from baseline in role function restrictive domain of Migraine Specific Quality of Life (MSQ) Questionnaire [At Weeek 12 and Week 24] The MSQ will be assessed by a questionnaire (Scores range from 0-100, higher scores indicate a better quality of life)
- Change from baseline in total MSQ score [At Weeek 12 and Week 24] The MSQ will be assessed by a questionnaire (Scores range from 0-100, higher scores indicate a better quality of life)
- Change in MSQ score to the minimally important difference/change (MID/MIC) [At Weeek 12 and Week 24] The MSQ will be assessed by a questionnaire (Scores range from 0-100, higher scores indicate a better quality of life)
- Change from baseline in total 6-item Headache Impact Test (HIT-6) score [At Week 12 and Week 24] The HIT-6 will be assessed by a questionnaire (scores range from 36-78 and higher scores indicate a greater impact of headache on subject's life)
- Change from baseline in HIT-6 score to MID/MIC [At Weeek 12 and Week 24] The HIT-6 will be assessed by a questionnaire (scores range from 36-78 and higher scores indicate a greater impact of headache on subject's life)
- Change from baseline in Short Form 12 (SF-12) Questionnaire score [At Weeek 12 and Week 24] The SF-12 will be assessed by a questionnaire (scores range from 0-100, with higher scores indicating better functioning)
- Chronic migraine status [At Week 24 (Week 21-24)] Chronic migraine status will be assessed by the daily eDiary and defined as number of participants with ≥15 MHD and ≥8 MMD
- Time to onset of effect [From first time point post randomisation to Week 24] Time to onset of effect is defined as the first time point post randomisation where MMD is reduced from baseline ≥50%
- Incidence of Treatment emergent adverse event (TEAEs) [Up to Week 24] An Adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
- Percentage of Participants with clinically significant changes in vital signs [From baseline up to Week 24] Percentage of participants with clinically significant changes in vital signs will be reported. The clinical significance will be graded by the investigator.
- Percentage of participants with clinically significant laboratory parameters (blood chemistry, haematology) [From baseline up to Week 24] Percentage of participants with clinically significant change in laboratory parameters (blood chemistry, hematology and coagulation) will be reported. The clinical significance will graded by the investigator.
- Treatment-emergence of suicidal ideation/suicidal behaviour [From baseline up to Week 24] It will be assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS) questionnaire that consists of 4 subscales:
Ideation severity subscale: questions answered yes/no, severity of ideation scored 1-5 with 5 being most severe
Intensity of ideation subscale : scores range from 2-25 with higher scores indicating more severe intensity of ideation.
Suicide behaviour subscale:4 types of suicidal behaviours are scored yes/no
Behaviour Lethality subscale: actual lethality/medical damage scores 0-5, with 5 being most severe ( death) and potential lethality scores 0-2 with 2 being more potentially lethal. - Percentage of participants with Binding antibodies to Dysport® [At Week 24] It will be assessed by collecting blood samples at baseline and Week 24. The determination of putative antibodies against BoNT-A will be evaluated using a validated method of electrochemiluminescence assays (ECLA) for the presence of binding antibodies to BoNT-A.
- Percentage of participants with neutralising antibodies to Dysport® [At Week 24] It will be performed only with confirmed positive samples in ECLA (confirmation of presence of binding antibodies) . The characterization of antibodies against BoNT-A will be evaluated using a validated method of cell-based assays (CBA) for the presence of neutralising antibodies to BoNT-A
