Dose escalation study of GT-001
This is a dose-escalation design trial. Twelve evaluable subjects (n=12) with BMIs of 30 to 40 kg/m2 will receive a single dose of placebo followed by study drug applied directly to the surface of the tongue mucosa with a disposable pipette followed by a one-day washout. A total of seven (7) doses will escalate to a dose of 2.5 mg.
