Study IDST001949
Study TitlePlasma Metabolome Normalization in Rheumatoid Arthritis following initiation of Methotrexate and the Identification of Metabolic Biomarkers of Efficacy
Study TypeClinical
Study SummaryMethotrexate (MTX) efficacy in the treatment of rheumatoid arthritis (RA) is variable and unpredictable, resulting in a need to identify biomarkers to guide drug therapy. This study evaluates changes in the plasma metabolome associated with response to MTX in RA with the goal of understanding the metabolic basis for MTX efficacy towards the identification of potential metabolic biomarkers of MTX response.
