Interventions

NameTypeDescription
GCS-100DRUG1.5 mg/m2 or 30 mg/m2 GCS-100. GCS-100 will be administered as IV infusions once weekly for 8 weeks with a 1 week and 4 week follow-up period and then at least every 30 days for up to a total of 1 year.
Placebo, SalineDRUGThe amount (in mg) of drug to be administered will be determined based on body surface area, which will be calculated based on body weight and height. The drug dose should be calculated on Day 1. Drug should be added to an infusion bag or syringe containing 0.9% Sodium Chloride Injection, USP. Drug be infused into a large vein via a large bore catheter to avoid local irritation and administered at no more than 2 mg/mL in no less than 60 mL.
