ArmTypeDescription
GTX-104EXPERIMENTALGTX-104 is a sterile concentrate of 10 mg nimodipine/5 mL (2 mg/mL), to be diluted in normal saline to obtain a dosing solution composed of dispersed micelles containing nimodipine for IV infusion. It will be administered as a continuous IV infusion of 0.15 mg/hour and a 30-minute IV bolus of 4 mg every 4 hours for up to 21 days
Oral nimodipineACTIVE_COMPARATOROral nimodipine is a soft gelatin capsule. The dose is 60 mg (two 30 mg capsules) every 4 hours for up to 21 consecutive days.
Treatment A (GTX-104 IV, Test):EXPERIMENTALNimodipine was administered by infusion over 72 hours.
Treatment B (NIMOTOP, RLD):EXPERIMENTALNimodipine capsules (RS) administered orally with 240 mL of water at a dose level of 60 mg (two 30 mg capsules) q4h for 72 hours.
