Funding allocation to different clinical trials.

The proposed study will consist of 8 weeks of treatment with either naltrexone or placebo in 10 subjects with pyromania.

The goal of the proposed study is to evaluate the efficacy and safety of naltrexone in pyromania. Ten subjects with DSM-IV pyromania will receive 8 weeks of naltrexone or placebo.

The proposed study will provide needed data on the treatment of a disabling disorder that currently lacks a clearly effective treatment.
