Just to clarify I just came accross a clinical trial for RA, when I was perusing the net so I accept no responsibility although it all looks above board.
If anyone wants to have a look its a company called ClinLife are looking for volunteers with RA, you have to have failed on 3 Dmards, and not currently on major meds it seems. The criteria is on the site.
You can apply on line. Depending on your situation you may want to look into it.
Again, I am not advertising or promoting, I just happened to see it.
