That IS good news!
It's already leaped over a massive hurdle, that sinks thousands of medical breakthroughs.
Usually scientists announce they have found a molecule that can do something fantastic. The molecule does it's job very well, and often without side-effects. However, the molecule is found in nature, (often in a healthy human body, that doesn't have the medical problem). Therefore the molecule can't be patented, and therefore it is too economically risky to proceed with trials on that exact molecule.
The molecule has to be synthetically altered, so it is patentable, so that the company can proceed with enough scientific trials to turn it into an accredited medicine, without bankrupting itself.
Usually at this point, the synthetic versions sink out of the media without a trace, because they don't do what the original molecule can, or they do it with hideous side-effects. Although scientists have found a treatment/cure, the treatment/cure never makes it into a medicine, because it's unpatentable.
In other cases synthetic versions do make it into medicines, but the medicines usually don't work as well, and have really bad side-effects, because the treating molecule is no longer one that already had a good metabolic pathway within the human body.
THIS trial is extra exciting to me, because the scientists are having good success with a molecule that is already synthetically altered, therefor making it already patentable, so this is the version they are envisaging using as the medicine itself.
