-
Low-dose cytarabine combined with thalidomide for adults with newly diagnosed LCH
This trial tests whether combining low-dose cytarabine with thalidomide is safe and effective for adults newly diagnosed with multisystem or multifocal Langerhans cell histiocytosis.
-
Targeted treatment for Langerhans Cell Histiocytosis using trametinib
This study is testing if trametinib, a new targeted therapy, can help children with Langerhans Cell Histiocytosis feel better and avoid the harsh side effects of traditional chemotherapy.
-
Evaluating FCN-159 for treating pediatric patients with recurrent LCH
This study is testing a new medication called FCN-159 to see if it can help children aged 2 to 16 with recurring Langerhans cell histiocytosis feel better.
-
Follow-up on health outcomes in patients with histiocytic disorders
This study looks at the long-term health effects of histiocytic disorders on around 6000 patients to see how these conditions impact their overall well-being and quality of life.
-
Using cobimetinib to treat refractory Langerhans cell histiocytosis and other histiocytic disorders
This study is testing if a drug called cobimetinib can help people with hard-to-treat Langerhans cell histiocytosis and other similar disorders feel better.
-
Comparing vinblastine/prednisone and cytarabine for treating Langerhans Cell Histiocytosis
This study is testing whether a combination of vinblastine and prednisone works better than cytarabine alone for treating Langerhans Cell Histiocytosis in kids and young adults.
