Phase 1 Study to Determine the Metabolism and Clearance of Baxdrostat
Study Details
Study Description
Brief Summary
This was a Phase 1, open-label, single dose study in healthy male subjects. The goals of this clinical trial were to determine how baxdrostat might be absorbed and metabolized using radioactive [14C] labeled baxdrostat. Subjects were administered a single oral dose of 10 mg containing approximately 100 μCi of [14C] baxdrostat. Subjects were to be confined to the study site for 9 to 15 days for blood, urine, and feces collections.

Outcome Measures
Primary Outcome Measures
- Total radioactivity recovery in urine and feces following administration of [14C] baxdrostat. [1 to 15 days after dosing]
Measurement of total radioactivity recovery in urine and feces to determine the routes, rates of elimination, and mass balance of total radioactivity from [14C] baxdrostat.
- Area under the curve [AUC] of baxdrostat and its primary metabolite (CIN-107M) following administration of [14C] baxdrostat to healthy male subjects. [1 to 15 days after dosing]
Area under the curve (AUC)0-∞ and AUC0-last will be determined for baxdrostat and CIN-107M in plasma.
- Cumulative baxdrostat and CIN-107M excreted in urine and fraction of baxdrostat renally excreted following administration of [14C] baxdrostat to healthy subjects. [1 to 15 days after dosing]
Determining cumulative amount of baxdrostat and CIN-107M excreted in urine, clearance of baxdrostat and CIN-107M, and fraction of dose excreted renally (baxdrostat only).
- Maximum concentration [Cmax] for baxdrostat and CIN-107M in plasma. [1 to 15 days after dosing]
Cmax will be determined based on measurement of baxdrostat and CIN-107M in plasma.
- Time to maximum concentration [Tmax] for baxdrostat and CIN-107M in plasma. [1 to 15 days after dosing]
Tmax will be determined based on measurement of baxdrostat and CIN-107M in plasma.
- Terminal elimination half-life (t1/2) for baxdrostat and CIN-107M in plasma. [1 to 15 days after dosing]
t1/2 for baxdrostat and CIN-107M in plasma will be determined based on measurement of baxdrostat and CIN-107M in plasma.
Secondary Outcome Measures
- Quantitative metabolic profiles of baxdrostat in plasma and excreta. [1 to 15 days after dosing]
To determine, where possible, the quantitative metabolite profiles in plasma, urine, and feces after [14C]-baxdrostat
- Identification of baxdrostat metabolites in plasma and excreta. [1 to 15 days after dosing]
To determine, where possible, the chemical structure of major metabolites in plasma, urine, and feces after [14C]-baxdrostat
- Incidence of treatment emergent adverse events following administration of [14C] baxdrostat. [1 to 15 days after dosing]
Incidence of adverse events will be used to assess the safety and tolerability of [14C] baxdrostat when administered to healthy subjects.
