NCT04933539
Background: Multiple myeloma (MM) is a tumor in which malignant plasma cells accumulate in the bone marrow. It can cause organ damage and is not curable. Researchers want to see if a combination drug treatment can help. Objective: To try to prevent or slow down developing MM and its associated organ damage by treating it while still in the smoldering phase with a mix of drugs known as DKd. Eligibility: People ages 18 and older with smoldering MM that is at high risk of converting to symptomatic MM. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Bone survey (x-rays of their bones) Spinal magnetic resonance imaging Bone marrow biopsy (a needle is used to remove bone marrow from their hipbone) Electrocardiogram (to check heart function) Lung function tests Treatment will be given in 28-day cycles. Participants will get daratumumab by injection under the skin. They will get carfilzomib intravenously (IV) through a tube inserted in a vein. They will get dexamethasone as oral tablets or as an IV. They will get all 3 drugs for 8 or 12 cycles. Then they will get daratumumab alone for up to 24 cycles. They may have stem cells collected. Participants will have frequent study visits. At these visits, they will repeat some screening tests. They will complete questionnaires. They will have imaging scans. For these scans, they may receive an oral or IV contrast. Participants will have a follow-up visit 30 days after treatment ends. Then they will have visits every 3-12 months. They will be followed on this study for life. ...
NCT06093867
Background: Stem cell transplants (called hematopoietic stem cell transplantation, or HSCT) are used to treat various diseases. But when the cells for this procedure are donated by someone other than the person who receives the HSCT ( allogeneic HSCT ), the recipient has an increased risk of lung inflammation and scarring. This happens when their immune cells attack healthy lung cells. In this natural history study, researchers will look for the best ways to detect developing lung inflammations earlier after an HSCT. Objective: To see if certain tests can detect early signs of lung inflammation in people after HSCT. Eligibility: People aged 5 to 70 years who will have HSCT as part of another NIH study. Design: Participants will undergo these tests prior to their HSCT. These tests will then be repeated regularly for 2 years: Ultra-low dose computed tomography (CT) scans. Participants will lie on a table that slides through a machine; the machine uses X-rays to get pictures of the inside of the body. This type of scan uses less radiation than normal CT scans. Bronchoscopy with lavage: Participants will be sedated. A flexible tube will be inserted through the mouth and into the airways. Salt water will be squirted into the lung, then sucked out to collect cells and fluids from the lung. Another tube with a camera may be inserted into the airways to take pictures. Blood tests. Blood will be drawn every 2 to 4 weeks. Pulmonary function tests. Participants will breathe into a machine to test their lung function. They will see how far they can walk in 6 minutes.
