Outcome Measures
Primary Outcomes (1)
Incidence of Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) as a Measure of Safety and Tolerability
Safety and tolerability are evaluated through adverse events (AEs), vital signs, physical examination, laboratory tests (hematology, blood biochemistry, urinalysis, coagulation function), 12-lead ECG, Holter monitoring, and pupil examination.
From informed consent up to Day 4 (End of study).
Secondary Outcomes (8)
Peak Plasma Concentration (Cmax) of DBM-1152A
Pre-dose (within 1 hour before dosing) up to 72 hours post-dose.
Area Under the Plasma Concentration-Time Curve From Time Zero to the Last Quantifiable Concentration (AUC0-t) of DBM-1152A
Pre-dose (within 1 hour before dosing) up to 72 hours post-dose.
Area Under the Plasma Concentration-Time Curve From Time Zero Extrapolated to Infinity (AUC0-∞) of DBM-1152A
Pre-dose (within 1 hour before dosing) up to 72 hours post-dose.
Time to Reach Peak Plasma Concentration (Tmax) of DBM-1152A
Pre-dose (within 1 hour before dosing) up to 72 hours post-dose.
Apparent Terminal Elimination Half-Life (t1/2) of DBM-1152A
Pre-dose (within 1 hour before dosing) up to 72 hours post-dose.
