POEMS syndrome

This phase 2 trial tests a combination of three drugs—carfilzomib, cyclophosphamide, and dexamethasone—in 20 people newly diagnosed with POEMS syndrome, a rare disorder affecting nerves and blood. The goal is to see if the regimen can reduce abnormal proteins and improve symptoms…

This study tests a device called Walkasins, worn on the lower legs, that vibrates to give sensory feedback about foot pressure. The goal is to see if using it daily for six months improves balance and walking in 200 adults aged 55+ with peripheral neuropathy. Participants will do…

This study looks at a specific gene (IGLV1-44) to understand why it causes two different diseases: AL amyloidosis and POEMS syndrome. Researchers will analyze blood and bone marrow samples from 100 adults with these conditions or multiple myeloma. The goal is to find genetic patt…

This study aims to see if a quick bedside sensory test can predict which painkiller—pregabalin, duloxetine, or a placebo—works best for people with nerve pain in their feet. About 190 adults with diabetic, chemotherapy-related, or idiopathic nerve pain will try each treatment for…

This study is collecting information from 4,000 adults with peripheral neuropathy (nerve damage) to better understand the condition. Researchers will combine standard tests with nerve ultrasound to see if it helps diagnose and track the disease. No new treatments are being tested…

This study looks at the gut microbiome (the bacteria living in the digestive system) of people with POEMS syndrome, multiple myeloma, MGUS, AL amyloidosis, and healthy household members. Participants provide stool samples at home using a collection kit. The goal is to understand …

This study is collecting nerve samples and biofluids from 400 people with ALS or peripheral neuropathies to find biological markers for early diagnosis and disease tracking. By analyzing individual cells, researchers hope to identify molecular changes that happen before symptoms …

This study creates a registry for adults with plasma cell disorders, such as multiple myeloma and amyloidosis. Researchers will collect health information and optional blood samples to better understand these conditions. The goal is to gather data that could support future resear…
