Relative Bioavailability of Intravenous GTX-104 Compared to Oral Nimodipine Capsules in Healthy Subjects

A Phase 1, Randomized, Two-Period Crossover Study to Evaluate the Relative Bioavailability of Intravenous GTX-104 Compared to Oral Nimodipine Capsules at Steady State in Healthy Male and Female Subjects

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).

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:

• History or presence of clinically significant medical illness, including, but not limited to, cardiovascular, pulmonary, hematologic, endocrine, immunologic, dermatologic, neurologic, psychiatric, renal, hepatic, chronic respiratory, or gastrointestinal disease, that could have interfered with the interpretation of the study.
• Had current or recent (within 6 months) history of gastrointestinal disease or any surgical or medical condition (eg, Crohn's or liver disease) that could potentially alter the absorption, metabolism, or excretion of the study drug.
