NCT05274243 | RECRUITING | Rheumatoid Arthritis

Detailed Description:

Rheumatoid arthritis (RA) is a systemic inflammatory autoimmune disease affecting 1% of the population. Aggressive treatment is a fundamental therapeutic strategy to improve disease-related outcomes and cardiovascular disease, which contributes to excess mortality in RA. Thus, therapeutics targeting novel pathways that treat RA and reduce cardiovascular risk are needed. A potential target is blocking the proinflammatory, immunogenic, and proatherogenic consequences of isolevuglandins (isoLGs). IsoLGs are highly reactive dicarbonyl products of oxidative stress that bind covalently to proteins causing conformational changes rendering them immunogenic and proinflammatory. Two decades of work at Vanderbilt led to the identification of 2-hydroxybenzylamine (2-HOBA) as a highly effective scavenger of reactive dicarbonyls such as isoLGs. Scavenging reactive dicarbonyls is preferable to using antioxidants because reactive oxygen species are necessary for normal cellular function. In animal models of autoimmunity, hypertension, and atherosclerosis 2-HOBA reduced inflammation, autoantibodies, blood pressure, and atherosclerosis, and in human phase 1 clinical studies in healthy volunteers 2-HOBA was well tolerated. In this phase 2 study investigators will randomize up to 32 subjects with RA meeting inclusion/exclusion criteria to 750mg 2-HOBA or matching placebo three times a day for 4 weeks. Randomized subjects will have study visits at week 0 and week 4. At each visit a history and physical exam with joint counts, questionnaire, blood draw and 24-hour blood pressure will be performed.
