A Study to Learn How the Study Medicine Called Zavegepant is Taken Up Into Blood and Breast Milk of Healthy Breast-Feeding Women

A PHASE 1 SINGLE INTRANASAL DOSE, OPEN-LABEL PHARMACOKINETIC STUDY OF ZAVEGEPANT IN HEALTHY LACTATING WOMEN

The purpose of the study is to look at the amount of zavegepant that is present in breast milk after single dose of zavegepant is sprayed through the nose in healthy breast-feeding women. This would allow to see if there are any possible risk to infants from medicines during breast-feeding.

The study is seeking for about 12 healthy breast-feeding females who are:

• 18 to 55 years of age.
• actively breast-feeding or producing breast milk.
• at least 2 weeks post-partum and not pregnant at present. Participants will not be allowed to breast-feed their infant from the evening of the day before to the first dose till 48 hours (2 days) after the dose.

Eligible participants will check into the clinical research unit (CRU) on Day -1. Participants will receive the zavegepant dose sprayed into the nose at the CRU on Day 1. The participants will stay at the CRU until the morning of Day 2. There will be collections of breast milk and plasma over 24 hours. Participants will be sent from the CRU on Day 2 and may begin to breastfeed their infant 48 hours (2 days) after the dose. A safety follow-up call will be done at about 28 to 35 days from the day the first dose of study medicine was given.

Description

Inclusion Criteria:

Participants must meet the following key inclusion criteria to be eligible for enrollment into the study:

Age and Sex:

1. Healthy lactating females who are actively breast-feeding or expressing breast milk, who are at least 2 weeks post-partum and not currently pregnant (must have a negative pregnancy test), and must be 18 to 55 years of age, inclusive, at the time of signing the Informed Consent Document (ICD).

   • Participants must be able to express at least 14 mL of breast milk over a 2-hour interval prior to the dose on Day 1.

   Other Inclusion Criteria:

2. Body mass index (BMI) 16.0-34.9 kg/m2 and body weight ≥45.0 kg (99 lb).
3. Female participants with history of acute migraine are allowed.
4. Participants must be willing to temporarily discontinue breastfeeding their infants for a total of 2.5 days (approximately 60 hours), ie, from the evening of the day before Day 1 through to 48 hours after the dose (approximately 8 AM the morning of Day 3). Participants must be willing to regularly pump breasts throughout the study and express breast milk according to a schedule designed to maintain lactation throughout the study period.

5. Participants must agree that breast milk expressed following zavegepant administration through 48 hours after the dose should be discarded and will not be fed to any infant.

Exclusion Criteria:

Participants with any of the following characteristics/conditions will be excluded:

1. Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological (with exception of acute migraine), or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
2. Clinically significant history of nasal conditions that may affect the administration or absorption of the nasal product (eg, severe septum deviation or nasal deformity, inflammation, perforation, mucosal erosion or ulceration, localized infection, congestion, polyposis, rhinorrhea, nasal surgery within the previous 6 months, or nasal trauma).
3. Significant history of seizure disorder other than a single childhood febrile seizure (eg, epilepsy).
4. History of gallstone or cholecystectomy.
5. Any other medical or psychiatric condition, including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality or other conditions or situations related to coronavirus disease 2019 (COVID-19) pandemic that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
6. Use of organic anion transporting polypeptide 1B3 (OATP1B3) inhibitors within 14 days or 5 half-lives, whichever is longer, before first dosing.
7. Participation in a clinical research study involving the administration of an investigational or marketed drug or device within 30 days prior to investigational product (IP) dosing, administration of a biological product in the context of a clinical research study within 90 days prior to IP dosing, or concomitant participation in an investigational study involving no drug or device administration.
8. Any clinically significant abnormal laboratory test results or positive test found during medical screening. A single repeat for positive drug screen may be allowed at the discretion of the principal investigator (PI).
9. Evidence of organ dysfunction or any clinically significant deviation from normal in physical examination or nasal inspection beyond what is consistent with the target population.

10. Participants with ANY of the following abnormalities in clinical laboratory tests at screening:

    • Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level > 1.5 × upper limit of normal (ULN);
    • Total bilirubin level >1.5 × ULN;
    • Estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73m².
11. Individuals who smoke more than 5 cigarettes or equivalent daily.
12. Presence of piercings or any physical findings in the nose that, in the opinion of the PI, would likely interfere with the successful completion of the dosing procedure.
13. Investigator site staff directly involved in the conduct of the study and their family members, site staff otherwise supervised by the investigator, and sponsor and sponsor delegate employees directly involved in the conduct of the study and their family members.
14. History of alcohol abuse or binge drinking and/or any other illicit drug use or dependence within 6 months of Screening. Binge drinking is defined as a pattern of 5 (male) and 4 (female) or more alcoholic drinks in about 2 hours. As a general rule, alcohol intake should not exceed 14 units per week (1 unit = 8 ounces (240 mL) beer, 1 ounce (30 mL) of 40% spirit, or 3 ounces (90 mL) of wine).

15. Any reason that, in the opinion of the PI, would prevent the participant from participating in the study.
