Vitamin B12 as a marker for disease activity in tocilizumab patients
Part of Immune system & allergy, Infections clinical trials.
This study looks at whether vitamin B12 levels in the blood can help tell if your disease is active or if you have an infection while being treated with tocilizumab. The goal is to find a simple way to monitor your condition without extra invasive tests.

This study looks at immune system blood tests in adults being treated for active tuberculosis and/or latent tuberculosis infection. The goal is to see if these “immune biomarkers” can help guide or improve tuberculosis management.
This study looks at how much tocilizumab (an injected biologic) stays in your blood. It aims to understand why some patients respond better and to help guide dosing. If you have rheumatoid arthritis that's mild or in remission and are already scheduled for this treatment, you might be able to join.
This trial tests whether the drug tocilizumab can help treat chronic active antibody-mediated rejection after a kidney transplant. It is for people whose kidney function is still fairly good and who have certain findings on biopsy.
This study looks at whether low vitamin D levels are linked to how active your inflammatory bowel disease is. If you have Crohn's or ulcerative colitis and have had recent vitamin D and disease activity tests, you may be able to join.
This study looks at blood “biomarkers,” or measurable body signals, in people with autoimmune diseases, vasculitis, or autoinflammatory conditions. The goal is to better understand these illnesses and how they relate to disease activity.
This trial tests whether a drug called tocilizumab can reduce joint pain and swelling in people with chronic CPPD (calcium pyrophosphate deposition disease), a type of arthritis. It is for those who have not gotten enough relief from standard treatments.
