Outcomes

Primary Outcome Measures

Number of participants with treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), and TEAEs leading to study drug discontinuation

Secondary Outcome Measures

Plasma concentrations of CY6463
Pharmacokinetic (PK) parameter: area under the concentration-time curve from time zero (predose) to 24 hours postdose (AUC0-24)
PK parameter: area under the concentration-time curve during a dosing interval (AUCtau)
PK parameter: average concentration during a dosing interval (Cavg)
PK parameter: maximum observed concentration (Cmax)
PK parameter: time to maximum observed concentration (Tmax)
PK parameter: minimum observed concentration (Cmin)
PK parameter: apparent systemic clearance (CL/F)
PK parameter: accumulation ratio based on a comparison of AUC values after single and multiple dosing (RAUC)
PK parameter: accumulation ratio based on a comparison of Cmax values after single and multiple dosing (RCmax)
