Mean Change From Baseline in Monthly Average Number of Migraine Days During 12-Week Period After the First Dose of Study Drug [1] | ||||||||||||
End point description |
A migraine day was defined as a calendar day where a participant reported either of the following: A calendar day (0:00 to 23:59) demonstrating at least 2 consecutive hours of a headache that was accompanied by ≥1 migraine symptom(s) or a calendar day demonstrating a headache of any duration that was treated with migraine specific medications (NSAIDs, paracetamol or triptans and ergot compounds). Monthly averages were derived and normalized to 28 days equivalent by formula: (number of days of efficacy variable over 12-week period/number of days with assessments recorded in e-diary for 12-week period) * 28. Least square (LS) mean was calculated using analysis of covariance (ANCOVA). Full analysis set (FAS): all randomized participants who received at least 1 dose of study drug and had at least 10 days of diary entries postbaseline for efficacy assessments on primary endpoint. Efficacy analysis was planned to be evaluated combined for both fremanezumab dose treatment groups.

Mean Change From Baseline in Migraine-related Disability Score at Week 12, as Measured by the Pediatric Migraine Disability Assessment (PedMIDAS) Questionnaire [5] | ||||||||||||
End point description |
PedMIDAS questionnaire is a 6-item instrument developed to assess headache-related disability. It has been validated in participants aged 4 through 18 years and includes questions related to the impact of headache on school performance, disability at home (for example, inability to do chores or homework), and social/sport functioning. Total score: that is, the sum of 6 questions, was used for grading of disability, with scores of 0 to 10, 11 to 30, 31 to 50, and >50 interpreted as disability grades 1 (little or no disability), 2 (mild disability), 3 (moderate disability), and 4 (severe disability), respectively. Higher scores indicated severe disability. LS mean was calculated using ANCOVA. FAS included all randomized participants who received at least 1 dose of study drug and had at least 10 days of diary entries postbaseline for efficacy assessments on the primary endpoint. Efficacy analysis was planned to be evaluated combined for both fremanezumab dose treatment groups.

Mean Change From Baseline in Quality of Life at Week 12, as Measured by Pediatric Quality of Life Inventory (PedsQL) Questionnaire [6] | ||||||||||||||||||||||||||||||
End point description |
PedsQL 4.0 (23-item health-related quality of life [QoL]) evaluates QoL in 4 areas: physical, emotional, social, and school functioning. For child and adolescent (8-18 years) and parent, a 5-point Likert scale was used to rate item severity (0=never a problem;1=almost never a problem; 2=sometimes a problem; 3=often a problem; 4=almost always a problem). For younger children (5-7 years), a 3-point Likert scale, anchored with a happy and a sad face, was used (0=not at all a problem; 2=sometimes a problem; 4=a lot of a problem). PedsQL yields a total QoL score and 2 summary scores: Physical Health Summary Score and Psychosocial Health Summary Score. To obtain scores, items were reverse scored, transformed to a 0 to 100 scale (0=100, 1=75, 2=50, 3=25, 4=0), and averaged; total scores near 0 indicated lower QoL, while scores approaching 100 indicated higher QoL. Analysis population: FAS. Efficacy analysis was planned to be evaluated combined for both fremanezumab dose groups.

Number of participants who developed ADAs were reported. The FAS included all randomized participants who received at least 1 dose of study drug and had at least 10 days of diary entries postbaseline for efficacy assessments on the primary endpoint. Here, 'Overall number of participants analyzed' = Participants who had Baseline and at least 1 postbaseline ADA assessment.

| Notes [7] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period. Justification: The end point is reporting statistics for the specified arms only. |

Substantial protocol amendments (globally) |
|||
| Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
21 Jun 2019 |
The primary reasons for this amendment were to improve the feasibility of the diary compliance requirement, to clarify the exclusion criterion for nerve stimulation or device, and to clarify the timing of injection site reaction assessment. |
||
05 Dec 2019 |
The primary reason for this amendment was to update the protocol with the dose to be used for participants <45.0 kg (120 mg SC monthly) following the completion of the Phase 1 pediatric pharmacokinetic study (TV48125-CNS-10141). |
||
20 Apr 2020 |
The primary reason for this amendment was to revise an exclusion criterion to exclude participants with a history of Stevens-Johnson Syndrome or toxic epidermal necrolysis syndrome. |
||
20 Aug 2020 |
The primary reason for this amendment was to provide guidance for remote assessments to minimize the time that participants and caregivers were required to spend at the study site. This consideration was triggered by the COVID-19 pandemic; however, remote assessments could be carried out on a regular basis to provide flexibility for participants, caregivers, and site staff. Patient reported outcomes assessed in this study, including the PedMIDAS, PedsQL, and Patient Global Impression of Improvement (PGI-I), as well as the C-SSRS, were valid to be conducted remotely, as confirmed by the scale authors. Instructions on remote data collection were available in the site operational manual. |
||
09 Dec 2021 |
The primary reason for this amendment was to revise the protocol to allow combined oral progestin and estrogen contraceptives, to expand the body mass index (BMI) upper limit to 120% of the 95th percentile in order reflect the real-world participant population, and to clarify potential sample size changes subsequent to the planned interim analysis. |
||
24 Sep 2023 |
- The primary reason for this amendment was to reduce the size of the study population and to update the inclusion criteria in order to help with enrollment and study completion.
- Updated study timelines according to new projections and reduced study population. |
