Treatment and study plan

GS-441524

Drug

750 mg administered as a solution

Other names: Parent nucleoside of remdesivir

Primary outcomes

  1. Emergence of treatment-related adverse events (AEs)

    Time frame: Day 7

    Treatment-related AEs are defined as significant changes to blood chemistry (CBC, CMP) or 6-lead ECG.

Secondary outcomes

  1. Pharmacokinetic (PK) Parameter: AUC0-24h of GS-441524 in Parts 1 and 2.

    Time frame: Intensive PK: Day 1 to Day 7

    AUC0-24h is defined as the concentration of drug over time between time 0 to time 24 hours.

  2. PK Parameter: AUClast of GS-441524 in Parts 1 and 2.

    Time frame: Intensive PK: Day 1 to Day 7

    AUClast is defined as the concentration of drug from time zero to the last observable concentration.

  3. PK Parameter: T1/2 of GS-441524 in Parts 1 and 2.

    Time frame: Intensive PK: Day 1 to Day 7

    T/2 is defined as the estimate of the terminal elimination half-life of the drug

  4. PK Parameter: Cmax of GS-441524 in Parts 1 and 2.

    Time frame: Intensive PK: Day 1 to Day 7

    Cmax is defined as the maximum observed concentration of drug.

  5. PK Parameter: Tmax of GS-441524 in Parts 1 and 2.

    Time frame: Intensive PK: Day 1 to Day 7

    Tmax is defined as the time (observed time point) of Cmax.

  6. PK Parameter: Clast of GS-441524 in Parts 1 and 2.

    Time frame: Intensive PK: Day 1 to Day 7

    Clast is defined as the last observable concentration of drug.

  7. PK Parameter: Tlast of GS-441524 in Parts 1 and 2.

    Time frame: Intensive PK: Day 1 to Day 7

    Tlast is defined as the time (observed time point) of Clast.

  8. PK Parameter: AUCtau of GS-441524 in Parts 1 and 2.

    Time frame: Intensive PK: Day 1 to Day 7

    AUCtau is defined as concentration of drug over time (the area under the concentration verses time curve over the dosing interval).
