I also do not understand why no proper clinical trial has been conducted so far with antibiotics. Antibiotics are cheap, so at least the phase 1-2 should have been done. Even CCSVI clinical trials have been commenced. We haven't even seen a preliminary study, which wouldn't cost too much.
One poster stated that neurologists organize clinical trials but that isn't correct....pharmaceutical companies organize them and they use neurologists to conduct them...often giving them a lot of grant money to do so. The cost of trials is quite expensive and these companies don't conduct them out of the goodness of their hearts....there has to be a good possibility of a big $$$ return somewhere down the line.
The antibiotics mentioned in the article are all off patent which means any drug company can manufacture them at a very low cost. So why would any company spend the money to conduct clinical trials that would allow anyone to duplicate the drugs in question if the trials proved successful? The simple answer...they don't and they won't.
This scenario has been going on in MS research for decades and isn't likely to change any time soon. So you see it's not about the health of MS patients but about business and profits. That's just the way it is whether we like it or not.
