Langerhans Cell Histiocytosis Clinical Trial
Official title:
Cytarabine Monotherapy for Adult Patients With Newly Diagnosed Langerhans Cell Histiocytosis: A Single Arm, Single Center, Prospective Phase 2 Study
Langerhans cell histiocytosis (LCH) is a rare, heterogeneous histiocytic disorder occurring in patients of all ages from neonates to the elderly. The current standard treatment protocol for children with de novo multisystem LCH is vinblastine plus prednisone. This regimen has never been proven effective for adults in a prospective study, since the only prospective trial evaluating the efficacy of a vinblastine/prednisone regimen in adults was prematurely closed due to unacceptable toxicities. A retrospective study showed an advantage for cytarabine monotherapy compared with vinblastine/prednisone in bone LCH patients. This phase 2, prospective, single-center study is designed to evaluate the efficacy and safety of cytarabine monotherapy in adults with newly diagnosed MS-LCH or LCH with multifocal single system (SS-m) involvement.
