Migraine Clinical Trial
Official title:
A Multicenter, Open-Label Study Evaluating the Long-Term Safety, Tolerability, and Efficacy of Monthly Subcutaneous Administration of Fremanezumab for the Preventive Treatment of Episodic and Chronic Migraine in Pediatric Patients 6 to 17 Years of Age
The primary objective of the study is to evaluate the long-term safety and tolerability of subcutaneous fremanezumab in the preventive treatment of migraine in pediatric participants 6 to 17 years of age (inclusive at enrollment in the pivotal study). Secondary objectives are to evaluate the efficacy of subcutaneous fremanezumab in pediatric participants with migraine and to evaluate the immunogenicity of fremanezumab and the impact of ADAs on clinical outcomes in pediatric participants exposed to fremanezumab. The total duration of the study is planned to be up to 84 months.

Primary | Incidence of abnormal physical examination findings | Day 1- Day 393 | ||
Primary | Yes/No suicidality ideation | Columbia-Suicide Severity Rating Scale (C-SSRS) The C-SSRS is an assessment tool that evaluates suicidal ideation and behavior. Scale range: Yes or No response to 10 questions, with minimum to maximum range of 0 to 10. Lower score represents better outcomes. | Day 1 - Day 393 | |
Secondary | Mean change in the number of headache days of at least moderate severity | Day 1 - Day 253 | ||
Secondary | Mean change in the number of migraine days | Day 1 - Day 253 | ||
Secondary | Proportion of participants reaching at least 50% reduction in the number of migraine days | Day 1 - Day 253 | ||
Secondary | Proportion of participants reaching at least 50% reduction in the number of headache days of at least moderate severity | Day 1 - Day 253 | ||
Secondary | Mean change in the number of days of use of any acute headache medications | Day 1 - Day 253 | ||
Secondary | Mean change in the PedMIDAS questionnaire score | The Pediatric Migraine Disability Assessment (PedMIDAS) is used to assess migraine disability across multiple domains of functioning including school, home, social, and recreational. The measure consists of 6 items measuring the number of days in which activities were missed as a result of headache/migraine. The measure yields a total score by summing items. Total scores correspond to one of four "disability grades:" 0-10 = little to no disability, 11-30 = mild disability, 31-50 = moderate disability, and >50 = severe disability. | Day 1 - Day 393 | |
Secondary | Proportion of participants developing antidrug antibodies (ADAs) throughout the study | The impact of ADAs on safety and efficacy will be analyzed if the number of ADA-positive participants allows. | Day 1 - Day 393 |
