Primary Outcome Measures:
  • Safety and tolerability of GS-6615 [ Time Frame: Up to 65 days ]
    The primary outcome measure is the safety and tolerability of GS-6615 including neurological findings, adverse events, clinical laboratory tests, vital signs and ECG data (PR, RR, QRS, QT, and QTc [Fridericia] interval).

  • Pharmacokinetic (PK) profile of GS-6615 [ Time Frame: Up to 65 days ]
    The primary outcome measure is the PK profile of GS-6615 which will be measured with Cmax, Tmax, AUCtau, AUC0-∞, T1/2, CL/F, VSS/F, and R.
