Detaljerad beskrivning
Immune modulation is a promising new approach for the treatment of RA. Studies have shown that immune cells in the joints of people in the early stages of RA react strongly against dnaJ peptides from bacteria. These immune cells may also cross-react with human dnaJ peptides in the joints to cause inflammation. dnaJ may help RA by "re-educating" the immune system and dampening the abnormal inflammatory immune response in RA.
This study will last 7 months. Participants will be randomly assigned to receive either dnaJ or placebo by mouth. At screening, participants will have medical history, physical, and medication assessment. At screening, at 6 study visits every month after the start of treatment, and at 1 month follow-up, participants will have a joint exam, blood and urine collection, and will fill out a questionnaire about their condition.
