Il-6 Inhibitor Sirukumab May Improve Anhedonia, But Not General Depression

January 25, 2019 · Posted in Potential Treatments 

cyclingAt a 2018 scientific meeting, researcher Giacomo Salvadore and colleagues reported that the drug sirukumab, a monoclonal antibody that targets the inflammatory marker Il-6 and that was originally developed to treat rheumatoid arthritis, did not have a statistically significant effect on overall depression compared to placebo. However, by the twelfth week of treatment, sirukumab did have a significant effect on anhedonia (loss of interest or pleasure in activities that one previously enjoyed).

The degree of improvement in anhedonia was significantly correlated with patients’ baseline levels of the inflammatory marker CRP. Since the inflammatory marker that sirukumab targets, Il-6, is one of those most often elevated in depression, it appears that more study of sirukumab would be warranted.
