Non-Langerhans cell histiocytosis

This phase 2 trial tests the drug selpercatinib in children and young adults (ages 1 to 21) with advanced cancers that have a specific genetic change called a RET alteration. The goal is to see if the drug can shrink tumors or stop them from growing. Only one participant has been…

This phase 2 trial is testing the drug larotrectinib in children and young adults (ages 1 to 21) with advanced solid tumors, non-Hodgkin lymphoma, or histiocytic disorders that have a specific genetic change called an NTRK fusion. The cancers have either come back after treatment…

This phase 2 study tests the chemotherapy drug lenalidomide (Revlimid) in 12 adults with one of three rare histiocyte disorders: Langerhans cell histiocytosis, Erdheim-Chester disease, or histiocytic sarcoma. The goal is to see how many patients achieve disease control or remissi…

This study offers voluntary screening for newborns in North Carolina to detect a wide range of rare health conditions early. Using a small blood sample already collected at birth, the program tests for dozens of disorders, including spinal muscular atrophy, cystic fibrosis, and m…

ScreenPlus is a large pilot program that offers families the option to have their newborn screened for a panel of rare genetic disorders, in addition to standard newborn screening. The study aims to screen 100,000 infants born at eight hospitals in New York. Researchers will eval…

This study looks at the genetic makeup of rare blood diseases like Castleman disease and Langerhans cell histiocytosis. Researchers will analyze blood or tissue samples from 135 participants to find genetic changes that could be targeted by existing or experimental therapies. The…

This study screens children and teens with advanced solid tumors, lymphomas, or histiocytic disorders to find genetic changes in their cancer cells. Participants undergo biopsies and scans to identify mutations that can be targeted by specific drugs. The goal is to see if matchin…

This study looks at how histiocytosis—a group of rare disorders—may affect memory, thinking, and brain structure. Researchers will test 13 adults with these conditions using thinking tasks and MRI scans. The goal is to better understand brain changes, not to provide treatment.…

This study looks at symptoms and lab tests to help doctors better diagnose acid sphingomyelinase deficiency (ASMD), also known as Niemann-Pick disease, a rare genetic disorder. Researchers will track changes in spleen and liver size using ultrasound over 12 months in 7 patients. …
