IVIG for anti-HMGCR muscle disease
This trial tests if IVIG (intravenous immunoglobulin, a donated blood product that helps the immune system) can improve muscle strength and reduce damage in people with anti-HMGCR immune-mediated necrotizing myopathy (a rare muscle disease where the immune system attacks muscle cells). It may help you if your muscle weakness is not too severe and you haven't tried IVIG before.

This study tests a new treatment for dry eye disease caused by Sjögren's syndrome. It may help people who still have dry eye symptoms even when using artificial tears.
Venice, FloridaAges 18 years+ - NCT06557564Recruiting
Liver transplant biopsy study using TruGraf
This study uses a blood test called TruGraf to check for liver transplant problems. It may help diagnose issues without a biopsy.
Toronto, OntarioAges 18 years+ - NCT06990711RecruitingPhase 1
Siltuximab for antibody-mediated rejection after lung transplant
This trial tests a drug called siltuximab to see if it can help treat a type of lung rejection called antibody-mediated rejection (AMR) in people who have had a lung transplant. You may be eligible if you are currently hospitalized for AMR and are already planning to receive standard treatments.
St Louis, MissouriAges 18 years+ - NCT06544915Recruiting
Synbiotic vs. probiotic for heart and gut health
This study tests whether a synbiotic (a combination of probiotics and prebiotics) is better than a probiotic alone or a placebo for improving gut health and heart health. If you are a healthy adult who hasn't taken antibiotics recently and has few heart disease risk factors, you may be able to join.

Combined Chinese and Western medicine for Sjögren's gland damage
This trial tests whether adding traditional Chinese medicine to standard care can help repair gland damage caused by Sjögren's syndrome. It is for people with primary Sjögren's who have a specific traditional Chinese medicine pattern called 'qi and yin deficiency'.
Beijing, Beijing MunicipalityAges 18–75 - NCT07311200RecruitingPhase 2
Study of D-2570 for active lupus
