Intervention model description: A maximum of 4 BAR 502 dose levels are preplanned to be investigated in separate sequential cohorts. Each of these cohorts will consist of 8 healthy male and female subjects (3 subjects of either sex on active treatment, 1 of either sex on placebo).

Each subject will participate in only one cohort.
Primary purpose: OTHER

Brief summary: This is a prospective, single-center, randomized, double-blind, placebo-controlled, single-ascending dose (SAD) phase 1 study to evaluate the safety and tolerability of single-ascending doses of BAR 502 in healthy male and female subjects.

Detailed description: This clinical trial will be the first-in-Human (FiH) study of BAR 502.

This study is planned to investigate up to 4 dose levels of BAR 502. Each dose level will consist of 8 healthy male and female subjects (ratio 1:1, male: female) to have 6 subjects being administered BAR 502 and 2 subjects being administered placebo (ratio 3:1, active: placebo).

The study is designed to meet the following objectives:

* Primary:

  * To evaluate the safety and tolerability of single-ascending doses of BAR 502 in healthy male and female subjects.
* Secondary:

  * To investigate the pharmacokinetics (PK) of single-ascending doses of BAR 502 in healthy male and female subjects;
  * To investigate the pharmacodynamics (PD) of single-ascending doses of BAR 502 in healthy male and female subjects.

Eligibility criteria: Inclusion Criteria:

1. Signed informed consent in a language understandable to the subject prior to any study-mandated procedure.

6. Estimated glomerular filtration rate calculated using the Cockcroft-Gault equation and normalized to an average surface area of 1.73 m2 ≥ 90 mL/min at Screening.
7. If woman, she meets one of the following criteria:

   1. is of non-childbearing potential; or
   2. is of childbearing potential and agrees to use an accepted non-hormonal or hormonal contraceptive method.
