There are 3 major phases in clinically testing a drug's safety and efficacy before it's brought to market, and it seems like they're close to starting the first one.
For all those interested in the 3 phases, here they are:
Phase 1: Small number of healthy volunteers to assess drug safety, toxicity, and pharmacokinetics.
Phase 2: Small number of patients with the disease of interest to test drug efficacy.
Phase 3: Large number of patients with the disease of interest to test effects of new treatment in comparison to those of existing treatments. This is where you see double-blind studies, etc.
Personally, this isn't terribly noteworthy. They've merely devised a new theory that's shown to be effective using animal models, and are still quite a ways away from seeing if similar results will occur with human testing. Of course, I do hope they see good results.
