Study Endpoints
Primary Endpoints
Incidence of Treatment-Emergent Adverse Events
Part A: Up to 7 days post-dose, Part B: Up to 7 days post final dose on day 10

Safety and tolerability of single or multiple ascending doses of ATH-1105 as measured by incidence of AEs, determined by clinical laboratory tests, physical examinations, vital signs measurements, and 12-lead ECG

Severity of Treatment-Emergent Adverse Events
Part A: Up to 7 days post-dose, Part B: Up to 7 days post final dose on day 10

Treatment-emergent adverse events will be graded on a 1 through 5 scale, based on severity as determined by the principal investigator.

Secondary Endpoints
Area under the plasma concentration time curve (AUC)
Part A: Up to 48 hours post-dose, Part B: Up to 48 hours post final dose on Day 10
Maximum observed plasma concentration (Cmax)
Part A: Up to 48 hours post-dose, Part B: Up to 48 hours post final dose on Day 10
Time to maximum observed plasma concentration (Tmax)
Part A: Up to 48 hours post-dose, Part B: Up to 48 hours post final dose on Day 10
