Clinical Trial Summary

This is a Phase 1, single center, randomized, two-period crossover study in healthy male and female subjects designed to evaluate the relative bioavailability (BA) and safety at steady state of two formulations of nimodipine: GTX 104 (nimodipine for intravenous [IV] infusion; test formulation) and nimodipine oral capsules, RS (reference formulation).

Eligibility

Inclusion Criteria:

• Subject had a body mass index between 18 and 32 kg/m2, inclusive.
• Subject was in good general physical health as determined by absence of clinically significant (CS) medical or psychiatric history, physical examination findings, vital signs, clinical laboratory evaluations, and 12-lead ECG measurements.

Exclusion Criteria:
