Exercise Training for the Improvement of Immune Activity and Treatment Outcomes During Immunotherapy for Non-small Cell Lung Cancer, BOOST Trial
NCT06983899
Recruiting
This clinical trial studies how well exercise training works in improving immune activity and treatment tolerance and response in patients with non-small cell lung cancer (NSCLC) who are receiving immunotherapy. Immunotherapy may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. The use of immunotherapy for the treatment of NSCLC has been rapidly increasing. Although immunotherapy have shown great potential in cancer therapy, no... Read More

Targeted Therapy to Increase RAI Uptake in Metastatic DTC
NCT05024929
Recruiting
Papillary thyroid cancer (PTC) is a common type of differentiated thyroid cancer (DTC) in children and represents the second most common cancer in adolescent females. Recently targeted drugs that block many of the genetic drivers of DTC have become available. While Investigators know that these drugs shrink DTC tumors in many cases, the impact on radioactive iodine (RAI) avidity has not been systematically studied.

211^At-BC8-B10 Before Donor Stem Cell Transplant in Treating Patients With High-Risk Acute Myeloid Leukemia, Acute Lymphoblastic Leukemia, Myelodysplastic Syndrome, or Mixed-Phenotype Acute Leukemia
NCT03128034
Recruiting
This phase I/II trial studies the side effects and best dose of 211\^astatine(At)-BC8-B10 before donor stem cell transplant in treating patients with high-risk acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or mixed-phenotype acute leukemia. Radioactive substances, such as astatine-211, linked to monoclonal antibodies, such as BC8, can bind to cancer cells and give off radiation which may help kill cancer cells and have less of an effect on healthy cells before d...
