Clinical Trial Summary

The study will evaluate safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single-ascending doses (SAD) and multiple ascending doses (MAD) of ABX-002 in healthy volunteers (HV)

Description:

The study will evaluate safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single-ascending doses (SAD) and multiple ascending doses (MAD) of ABX-002 in healthy volunteers (HV) to identify repeated dose levels that are safe and well-tolerated.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety and tolerability of ABX-002 in healthy subjects as assessed by incidence of treatment-emergent AEs (TEAEs) and SAEs	Safety will be assessed by AEs, laboratory assessments (eg, hematology, coagulation, blood chemistry, THA markers, bone turnover biomarkers, cardiac and muscle markers, SHBG), urinalysis, pregnancy tests, vital signs (supine, orthostatic), analysis of safety ECGs, incidence and duration of selected cardiac rhythms on Holter monitoring, presence of drug-related excessive slowing or EA on EEG, slit lamp examination of the lens for cataract, and physical and neurological examinations	Change from baseline
Secondary	Pharmacokinetics of ABX-002 in health subjects as assessed by maximum plasma concentration (Cmax) towards determination of the optimal PK dose	Determination of maximum plasma concentration (Cmax)	Day 1 to Day 5
Secondary	Pharmacokinetics of ABX-002 in health subjects as assessed by time to maximum concentration (Tmax) towards determination of the optimal PK dose	Determination of time to maximum concentration	Day 1 to Day 5
Secondary	Pharmacokinetics of ABX-002 in health subjects as assessed in healthy subjects as assessed by plasma exposure (AUC0-t, AUC0-inf) determination of the optimal pharmacokinetic dose	Determination of plasma exposure (AUC0-t, AUC0-inf)	Day 1 to Day 5
Secondary	Pharmacokinetics of ABX-002 in healthy subjects as assessed by terminal elimination half life (t1/2) determination of the optimal pharmacokinetic dose	Determination of terminal half life	Day 1 to Day 5
