The purpose of the study is to learn about safety and how the body processes the study medicine called Zavegepant (PF-07930207) in children with a history of migraine. This study helps understand how the medicine is changed and removed from the body after taking it.
This study is seeking participants who:
* Are children aged between 6 and less than 12 years old * Have had migraine for at least 6 months. * Weigh more than 15 kilograms
All participants in this study will receive zavegepant as a nasal spray once (one spray into one nostril). The dose of the study medicine that each participant receives will depend on how much the participant weighs.
The study will look at the experiences of the participants receiving the study medicine and collect data to better understand the possible benefits and unwanted effects of different doses of the study medicine.
Participants will take part in this study for up to 10 weeks. During this time, they will have 3 study visits at the study clinic, and 2 follow-up phone calls.
Participants aged 6 years to less than 12 years.
Documented medical history of migraine with or without aura for at least 6 months before the Screening Visit.
Weight >15 kg at the Screening Visit
Evidence or history of clinically significant disease.
Continuous migraine (defined as an unrelenting headache) within 1 month prior to Screening Visit.
Atypical migraine types, complications of a migraine, or a confounding and clinically significant pain syndrome.
Conditions that may affect the administration or absorption of the nasal product
Single group
Zavegepant
DrugZavegepant 5 mg or 10 mg (dose is weight-dependent)
Maximum Observed Plasma Concentration (Cmax)
Cmax is defined as the maximum observed plasma concentration of zavegepant after administration of a single dose
Time to Reach Maximum Observed Plasma Concentration (Tmax)
Tmax is defined as the time to reach maximum observed plasma concentration
Area Under the Curve From Time Zero to infinity.
AUC (0 - inf) is defined as area under the concentration-time curve from time 0 to infinity.
Number of Participants with All-Causality Treatment-emergent Adverse Events (TEAEs)
An AE is any untoward medical occurrence in a participant who received study intervention without regard to possibility of causal relationship with the study intervention. SAE is defined as one of the following: is fatal or life threatening; results in persistent or significant disability/incapacity; constitutes a congenital anomaly/birth defect; is medically significant; requires inpatient hospitalization or prolongation of existing hospitalization. Treatment-emergent AE is defined as an AE with onset date occurring during the on-treatment period. AEs include all SAEs and non-SAEs.
Number of participants with clinically significant abnormal vital signs
Vital sign measurements include temperature, respiratory rate, pulse rate, and blood pressure.
Number of participants with clinically significant abnormal laboratory findings
Laboratory assessment includes hematology, chemistry and urinalysis. Clinical significance of laboratory abnormalities was judged by investigator.
Number of Participants with categorical scores on the Columbia Suicide Severity Rating Scale (C-SSRS)
The C-SSRS is an interview-based rating scale to systematically assess suicidal ideation and suicidal behavior. The C-SSRS assessment MUST be performed by an adequately trained, certified, and delegated rater. C-SSRS assessed whether participant experienced any of the following 1: completed suicide, 2: suicide attempt (response of "yes" on "actual attempt"), 3: preparatory acts toward imminent suicidal behavior ("yes" on "aborted attempt", "interrupted attempt", "preparatory acts or behavior"), 4: any suicidal behavior or ideation, suicidal ideation ("yes" on "wish to be dead", "non-specific active suicidal thoughts", "active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent"), 7: self-injurious behavior, no suicidal intent ("yes" on "has participant engaged in non-suicidal self-injurious behavior").
