简要总结
This is a double-blind, randomized, placebo-controlled, phase I study in normal healthy volunteers. Study treatment includes single doses of MNTX and placebo. In addition, half of each active treatment group is further randomized to a second, replicate dose of MNTX, and the placebo group receives an additional placebo dose.
