- Clearance (CL) or apparent oral clearance (CL/F) as measured by PK sampling [ Time Frame: Data will be collected up to 90 days from the time of consent. For participants with Down Syndrome enrolling at sites designated as Down Syndrome sites, participants will be in the study for up to 210 days. ]
- Volume of distribution (V) or apparent oral volume of distribution (V/F) as measured by PK sampling [ Time Frame: Data will be collected up to 90 days from the time of consent. For participants with Down Syndrome enrolling at sites designated as Down Syndrome sites, participants will be in the study for up to 210 days. ]
- Elimination rate constant (ke) as measured by PK sampling [ Time Frame: Data will be collected up to 90 days from the time of consent. For participants with Down Syndrome enrolling at sites designated as Down Syndrome sites, participants will be in the study for up to 210 days. ]
- Half-life (t1/2) as measured by PK sampling [ Time Frame: Data will be collected up to 90 days from the time of consent. For participants with Down Syndrome enrolling at sites designated as Down Syndrome sites, participants will be in the study for up to 210 days. ]
- Absorption rate constant (ka) as measured by PK sampling [ Time Frame: Data will be collected up to 90 days from the time of consent. For participants with Down Syndrome enrolling at sites designated as Down Syndrome sites, participants will be in the study for up to 210 days. ]
- AUC (area under the curve) as measured by PK sampling [ Time Frame: Data will be collected up to 90 days from the time of consent. For participants with Down Syndrome enrolling at sites designated as Down Syndrome sites, participants will be in the study for up to 210 days. ]
- Maximum concentration (Cmax) as measured by PK sampling [ Time Frame: Data will be collected up to 90 days from the time of consent. For participants with Down Syndrome enrolling at sites designated as Down Syndrome sites, participants will be in the study for up to 210 days. ]
- Time to achieve maximum concentration (Tmax) as measured by PK sampling [ Time Frame: Data will be collected up to 90 days from the time of consent. For participants with Down Syndrome enrolling at sites designated as Down Syndrome sites, participants will be in the study for up to 210 days. ]
