Brief summary

The goal of the study is to see what happens to levels of midazolam and digoxin in a person's body over time (a pharmacokinetic or PK study). Researchers will compare what happens to midazolam and digoxin in the body when it is given with and without another medicine called calderasib. Researchers are testing if digoxin and midazolam levels in the body are different when digoxin and midazolam are given with or without calderasib.

Primary

MeasureTime frameDescription
Time to Maximum Plasma Concentration (Tmax) of MidazolamPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the Tmax of midazolam.
Area Under the Concentration-Time Curve from Time 0 to Infinity (AUC0-Inf) of MidazolamPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the AUC0-inf of midazolam.
Area Under the Concentration-Time Curve from Time 0 to Last (AUC0-Last) of MidazolamPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the AUC0-last of midazolam.
Area Under the Concentration-Time Curve from Time 0 to 24 hours (AUC0-24hr) of MidazolamPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the AUC0-24hr of midazolam.
Maximum Plasma Concentration (Cmax) of MidazolamPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the Cmax of midazolam.
Apparent Terminal Half-life (t1/2) of MidazolamPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the t1/2 of midazolam.
Apparent Clearance (CL/F) of MidazolamPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the CL/F of midazolam.
Apparent Volume of Distribution During Terminal Phase (Vz/F) of MidazolamPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the Vz/F of midazolam.
AUC0-Inf of DigoxinPredose and at designated timepoints up to 120 hours postdoseBlood samples will be collected to determine the AUC0-inf of digoxin.
AUC0-Last of DigoxinPredose and at designated timepoints up to 120 hours postdoseBlood samples will be collected to determine the AUC0-last of digoxin.
AUC0-24hr of DigoxinPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the AUC0-24hr of digoxin.
Cmax of DigoxinPredose and at designated timepoints up to 120 hours postdoseBlood samples will be collected to determine the Cmax of digoxin.
Tmax of DigoxinPredose and at designated timepoints up to 120 hours postdoseBlood samples will be collected to determine the Tmax of digoxin.
t1/2 of DigoxinPredose and at designated timepoints up to 120 hours postdoseBlood samples will be collected to determine the t1/2 of digoxin.
CL/F of DigoxinPredose and at designated timepoints up to 120 hours postdoseBlood samples will be collected to determine the CL/F of digoxin.
Vz/F of DigoxinPredose and at designated timepoints up to 120 hours postdoseBlood samples will be collected to determine the Vz/F of digoxin.

Secondary

MeasureTime frameDescription
AUC0-24hr of CalderasibPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the AUC0-24hr of calderasib.
AUC0-Last of CalderasibPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the AUC0-last of calderasib.
Cmax of CalderasibPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the Cmax of calderasib.
C24 of CalderasibPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the Cmax of calderasib.
Tmax of CalderasibPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the Tmax of calderasib.
t1/2 of CalderasibPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the t1/2 of calderasib.
Cmax Accumulation Ratio of CalderasibPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the Cmax accumulation ratio of calderasib. The accumulation ratio is the ratio of Predose Cmax to the 24 hour Cmax
AUC0-24 Accumulation Ratio of CalderasibPredose and at designated timepoints up to 24 hours postdoseBlood samples will be collected to determine the AUC0-24 accumulation ratio of calderasib. The accumulation ratio is the ratio of Predose AUC0-24 to the 24 hour AUC0-24.

Total Amount of Drug Excreted in Urine (Ae) of DigoxinPredose and at designated timepoints up to 120 hours postdoseUrine samples will be collected to determine the Ae of digoxin.
Fraction of Unchanged Digoxin in Urine (Fe)Predose and at designated timepoints up to 120 hours postdoseUrine samples will be collected to determine the Fe of digoxin.
Number of Participants Who Experience an Adverse Event (AE)Up to approximately 1 monthAn AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experience an AE will be reported.
Number of Participants Who Discontinue Study Due to an AEUp to approximately 1 monthAn AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who discontinue study due to an AE will be reported.
