Summary

This trial is testing if a drug called clofarabine can treat Langerhans Cell Histiocytosis (LCH) and other histiocytic disorders.

Who is the study for?
This trial is for people of all ages with active Langerhans Cell Histiocytosis (LCH) or related disorders, who have tried at least one treatment before. They must not be pregnant, breastfeeding, or have had certain other cancers within the last 5 years. Participants need to have a performance score above 70%, normal kidney and liver function tests, and can't be on drugs that could harm their kidneys during the study.
What is being tested?
The drug being tested is clofarabine for treating LCH and similar conditions. The study will look at how well it works in patients who've already tried other treatments without success. It's given under controlled conditions to monitor its effectiveness and safety.
What are the potential side effects?
Clofarabine may cause side effects like nausea, vomiting, diarrhea, fever, rash, fatigue, liver problems (increased bilirubin), blood disorders such as low counts of white cells or platelets which might increase infection risk.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Recurrent or Refractory Langerhans Cell Histiocytosis (LCH) + ClofarabineExperimental Treatment1 Intervention
Participants with recurrent or refractory LCH defined as with multi-focal or multi-system disease who have recurred (or have refractory disease) after at least one prior systemic chemotherapy regimen. Patient will receive Clofarabine administered via IV on days 1-5, 25 mg/m2/day per cycle for 2 cycles. At the end of cycle 2 if no disease progression, will continue with same dose for maintenance treatment for 4 additional cycles.
Group II: LCH-related disorders + ClofarabineExperimental Treatment1 Intervention
Participants with LCH-related disorders defined as who require systemic chemotherapy including participants with Rosai Dorfman Disease (RDD) who have not responded to or recurred after treatment with corticosteroids. Erdheim Chester Disease (ECD) subjects who have confirmed presence of BRAF V600E mutation must have not responded to, have recurred after, or be unable to receive treatment with a BRAF inhibitor. Patient will receive Clofarabine administered via IV on days 1-5, 25 mg/m2/day per cycle for 2 cycles. At the end of cycle 2 if no disease progression, will continue with same dose for maintenance treatment for 4 additional cycles.
