Primary Outcome Measures
NameTimeMethod
Pharmacokinetics (PK): Area under the concentration-time curve (AUC) from time 0 to the time of the last quantifiable concentration (AUCt) of GBT440 in whole bloodpredose, 1, 2, 4, 6, 8, 12, 16, 24, 48, 72, and 96 hours postdose, and Day 12, Day 20, and Day 28 for each period
Pharmacokinetics (PK): AUC from time 0 extrapolated to infinity (AUCinf) of GBT440 in whole bloodpredose, 1, 2, 4, 6, 8, 12, 16, 24, 48, 72, and 96 hours postdose, and Day 12, Day 20, and Day 28 for each period
Pharmacokinetics (PK): Maximum observed concentration (Cmax) of GBT440 in whole bloodpredose, 1, 2, 4, 6, 8, 12, 16, 24, 48, 72, and 96 hours postdose, and Day 12, Day 20, and Day 28 for each period
Secondary Outcome Measures
NameTimeMethod
Pharmacokinetics (PK): Terminal elimination half-life (t½) of GBT440 in whole bloodpredose, 1, 2, 4, 6, 8, 12, 16, 24, 48, 72, and 96 hours postdose, and Day 12, Day 20, and Day 28 for each period
Pharmacokinetics (PK): Apparent oral clearance (CL/F) of GBT440 in whole bloodpredose, 1, 2, 4, 6, 8, 12, 16, 24, 48, 72, and 96 hours postdose, and Day 12, Day 20, and Day 28 for each period
Pharmacokinetics (PK): The time that Cmax was observed (tmax) of GBT440 in whole bloodpredose, 1, 2, 4, 6, 8, 12, 16, 24, 48, 72, and 96 hours postdose, and Day 12, Day 20, and Day 28 for each period
Pharmacokinetics (PK): Apparent volume of distribution during the terminal phase (Vz/F) of GBT440 in whole bloodpredose, 1, 2, 4, 6, 8, 12, 16, 24, 48, 72, and 96 hours postdose, and Day 12, Day 20, and Day 28 for each period
