Study Arms (3)
TRX-100 Dose Level 1
EXPERIMENTALParticipants in this arm will receive a lower single oral dose of the investigational drug, TRX-100.
TRX-100 Dose Level 2
EXPERIMENTALParticipants in this arm will receive a higher single oral dose of the investigational drug, TRX-100.
Standard of Care (SOC)
ACTIVE COMPARATORParticipants in this arm will not receive the investigational drug. Instead, they will receive the current standard of care treatment. This arm serves as a comparator to evaluate the effects of the investigational drug.
Interventions
CEN inhibitor, dosage form - capsules, dosing regimen - QD
