Outcome Measures

Primary Outcomes (7)

  • Incidence and severity of treatment-emergent adverse events (TEAEs) including serious adverse events (SAEs), and discontinuations due to TEAEs

    Up to 20 days

  • PK parameter: The area under the concentration-time curve from time zero extrapolated to infinity (AUC0-∞) of DNL343 in plasma

    Up to 20 days

  • PK parameter: The area under the concentration-time curve from zero to 12 or 24 hours for twice daily (BID) or once daily (QD) dosing, respectively (AUC0-τ) of DNL343 in plasma

    Up to 20 days

  • PK parameter: Maximum observed concentration (Cmax) of DNL343 in plasma

    Up to 20 days

  • PK parameter: Area under the concentration-time curve from time zero to the time of last quantifiable concentration (AUC[0-last]) of DNL343 in plasma

    Up to 20 days

  • PK parameter: Time to maximum observed concentration (Tmax) of DNL343 in plasma

    Up to 20 days

  • PK parameter: Apparent terminal elimination rate constant (λz) with the respective t½ of DNL343 in plasma

    Up to 20 days

Secondary Outcomes (5)

  • PK parameter: The amount of DNL343 excreted in urine from time zero to 48 hours postdose (Ae48)

    Up to 20 days

  • PK parameter: Estimation of renal clearance (CLR)

    Up to 20 days

  • PK parameter: Concentration of DNL343 in cerebrospinal fluid (CSF)

    Up to 20 days

  • The PD of DNL343 in blood as measured by percent reduction of integrated stress response (ISR) protein levels measured by enzyme-linked immunosorbent assay (ELISA)

    Up to 20 days

  • The PD of DNL343 in blood as measured by percent reduction in ISR gene expression levels measured by quantitative polymerase chain reaction (qPCR)

    Up to 20 days
