A Phase 4, Open-Label, Single-Dose Study to Evaluate Sunosi® (Solriamfetol) Pharmacokinetics in Breast Milk and Plasma of Healthy Postpartum Women Following Oral Administration of Sunosi®

JZP110-401

The purpose of study JZP110-401 is to evaluate solriamfetol pharmacokinetics (PK) in the breast milk and plasma of healthy postpartum women following the administration of the drug. The study also aims to estimate the potential daily solriamfetol dose received by the infant from the breast milk of the nursing mother. The safety and tolerability of single oral doses of solriamfetol will also be assessed.
