This early-stage trial tests a radioactive drug that seeks out and delivers radiation directly to cancer cells with a specific protein (somatostatin receptor). It is for adults with advanced lung, kidney, head and neck, digestive tract, or adrenal gland tumors that cannot be remo…

This phase 2 trial tests enasidenib, a daily pill that targets the IDH2 gene mutation, in 40 adults with rare cancers of the nasal cavity or skull base that have spread or come back. Participants take the drug once daily in 28-day cycles, and researchers will track how long the c…

This study tests giving chemotherapy and immunotherapy before standard surgery for head and neck cancer. The goal is to shrink tumors enough so that surgeons can perform less extensive, function-preserving operations, reducing damage to swallowing, speech, and vision. The trial e…

This study tests two at-home treatments—smell training and a gentle nerve stimulation device—for people with long COVID who have lost or distorted their sense of smell. About 145 adults will do daily sessions at home and attend three clinic visits over 12 weeks. The goal is to se…

This study is following children and adults with olfactory neuroblastoma, a rare cancer of the nasal cavity, to learn more about how the disease behaves over time. Researchers will collect medical records, blood samples, and survey responses from 525 participants to track symptom…

This study follows 80 children aged 2-8 with cystic fibrosis to see how highly effective CF drugs (Kalydeco or Trikafta) impact sinus disease and sense of smell. Researchers will use MRI scans, smell tests, and quality-of-life surveys over two years. The goal is to understand whe…

This study is a registry that follows 500 people with smell or taste disorders to learn more about how these conditions progress and affect quality of life. Participants complete standard tests and questionnaires during their clinic visits. The goal is to better understand these …
