Study summary

This is a Phase 1 study carried out at a single site in 88 healthy male subjects and healthy female subjects of non childbearing potential to investigate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of DNL343.

What researchers measure

Primary outcomes

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

    Time frame: Up to 20 days

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

    Time frame: Up to 20 days

  3. 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

    Time frame: Up to 20 days

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

    Time frame: Up to 20 days

  5. 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

    Time frame: Up to 20 days

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

    Time frame: Up to 20 days

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

    Time frame: Up to 20 days

Secondary outcomes

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

    Time frame: Up to 20 days

  2. PK parameter: Estimation of renal clearance (CLR)

    Time frame: Up to 20 days

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

    Time frame: Up to 20 days

  4. 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)

    Time frame: Up to 20 days

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

    Time frame: Up to 20 days
