This trial tests whether two approved drugs, dabrafenib and trametinib, can treat rare cancers that have a specific genetic change called BRAF V600. These drugs are already used for melanoma and lung cancer, but researchers want to see if they help people with other cancer types.…

This trial is testing two drugs, vemurafenib and cobimetinib, already approved for melanoma, in adults with other rare cancers that have a specific genetic change called BRAF V600 mutation. The goal is to see if the combination can shrink tumors or stop them from growing. About 3…

This phase 2 study tests the drug cobimetinib in children and adults with Langerhans cell histiocytosis and related disorders that have come back or not responded to standard treatment. Cobimetinib blocks a growth signal that goes haywire in these diseases. The study will enroll …

This study follows 6,000 people with histiocytic disorders (like Langerhans cell histiocytosis) to understand long-term health problems, pain, mental health, and causes of death. Researchers compare participants to healthy controls to identify factors that lead to new health issu…

This early-phase study is testing a new imaging agent called [68Ga]-pentixafor to see how well it shows up on PET/CT scans in people with certain blood cancers (like multiple myeloma and non-Hodgkin lymphoma) and rare immune cell tumors. About 30 participants will get the agent a…

This study creates a registry for people with Erdheim-Chester disease and related histiocytoses. Researchers will collect medical information and patient experiences over time to better understand these rare conditions. Up to 500 participants will be enrolled, and some may be ask…
