Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study will be conducted in two parts. Part A single ascending dose (SAD) with total 5 Cohorts and Part B Multiple ascending dose (MAD).
Oral doses of PXS-5505A capsules (10 mg, 50 mg, 100 mg, 200 mg, and 300 mg) will be administered to subjects in SAD cohorts.
Oral doses of PXS-5505A capsules (100 mg and 200mg) are planned to be administered to subjects in MAD Cohorts based on available safety, PK and PD data from the SAD Cohorts. The ascending doses used for MAD Cohorts are planned for 100 and 200 mg based on the availability of safety, PK and PD data from SAD Cohorts.
MAD Cohorts will start once all the SAD Cohorts are completed and evaluated with safety and PK/PD data

Outcomes
Primary outcome [1] 319146 0
The primary endpoints of the study are to evaluate safety and tolerability of single ascending or repeated doses of PXS-5505A by measuring Adverse Events, Change in ECGs, Blood pressure, Heart Rate and Laboratory Assessments.

Safety and tolerability of PXS-5505A will be assessed by observation of the incidence, severity, causality and seriousness of adverse events ; vital signs (blood pressure, heart rate, respiratory rate, and oral temperature); laboratory tests (drug and alcohol screening, hematology and coagulation, and biochemistry); and medical surveillance by clinical site staff. Possible and know AE may be liver inflammation and increased blood pressure.
Timepoint [1] 319146 0

Vital signs to be assessed at Screening, Check-in and on Day 1 at pre-dose within 30 minutes and at 15 and 30 minutes and 1, 2, 4, 6, 8 and 12 hours, and on Day 2, Day 3, Day 4, and Day 5 at 24, 48, 72, and 96 hours post-dose respectively
