Brief Summary

The aim of this early phase two-part study was to compare the bioavailability (BA) pharmacokinetics (PK) and pharmacodynamics (PD) of racemic pindolol with the benzoate salt of the S-enantiomer of pindolol (ACM-001.1) and provide safety information. A total of 51 healthy male and female subjects were enrolled, and 48 healthy subjects completed the study.

Part 1 consisted of two Groups to compare BA and PK, Group 1 received two treatment sequences of a single dose of ACM-001.1 versus racemic pindolol; Group 2 ran in parallel with Group 1 and assessed the PK of a single dose of racemic pindolol in a single period.

Part 2 consisted of four groups, to evaluate the steady state PK and PD of ACM-001.1 with multiple ascending doses over 4 days.
