Brief Summary

First-in-human, single centre, two parts, dose-escalation, parallel-group, safety, tolerability, pharmacokinetic and pharmacodynamic Phase I study. Part A: randomised, double-blind, placebo-controlled, single ascending dose study.

Part B: open label, multiple ascending dose study.

Detailed Description

First-in-human, single centre, two parts, dose-escalation, parallel-group, safety, tolerability, pharmacokinetic and pharmacodynamic Phase I study. Part A: randomised, double-blind, placebo-controlled, single ascending dose study to evaluate the safety and tolerability of BAR502 and matching placebo across 4 single ascending doses administered to 4 cohorts of 8 healthy subjects each.

Part B: open label, multiple ascending dose study to evaluate the safety and tolerability of two ascending doses of BAR502, considered as safe in study Part A, when administered as multiple doses to 2 cohorts of 10 healthy subjects each.

Conditions

Study Groups

BAR502 single dose

Each subject will receive an oral single-dose of BAR 502 \[Study Part A\]

Group Type: EXPERIMENTAL

BAR502 single dose

Intervention Type: DRUG

Single oral doses of BAR 502/placebo will be administered as film-coated tablets, in the morning of Day 1, with 150 mL of water, after an overnight fasting of at least 8 hours.

BAR 502 film-coated tablets are available at dose strengths of 3, 10 and 50mg. A maximum of 4 dose levels are pre-planned (3, 10, 30 and 60mg).

Placebo single dose

Each subject will receive an oral single-dose of placebo \[Study Part A\]

Group Type: PLACEBO_COMPARATOR

Placebo single dose

Intervention Type: DRUG

Matching BAR 502 placebo film-coated tablets will be given to 2 out of 8 subjects in each cohort using the same regimen as outlined for the active study treatment

BAR502 multiple doses

Each subject will receive a dose of BAR502 once a day for 14 days \[Study Part B\]

Group Type: EXPERIMENTAL

BAR502 multiple doses

Intervention Type: DRUG

The 2 multiple ascending doses selected based on results of study part A will be administered to 2 study cohorts of 10 subjects each. The IMP will be orally administered once a day from Day 1 to Day 14, at 8:00±1 h, for a total of 14 doses.
