The main aim of the study is to evaluate efficacy and safety profile Ocrelizumab (OCR), Rituximab (RTX), Cladribine (CLA), employed as Natalizumab (NTZ) exit-strategies in Relapsing-Remitting Multiple Sclerosis (RRMS) patients at high-risk for progressive multifocal leukoencephalopathy (PML).

OBJECTIVE To evaluate the safety and tolerability of subcutaneous (s.c.) cladribine therapy in patients with chronic progressive multiple sclerosis (CPMS), and to evaluate the effects on lymphocyte subsets. BACKGROUND Cladribine, a synthetic antineoplastic agent with immunosuppressive effects, may favourably affect the course of CPMS. However results of a previous reported clinical trial show...

Cladribine therapy may be beneficial in advanced forms of pulmonary Langerhans cell histiocytosis, even that with multiple cystic changes http://ow.ly/yeLr30i0Tt6.

Nucleoside analogs are rationally designed anticancer agents that disrupt DNA and RNA synthesis. Fludarabine and cladribine have important roles in the treatment of hematologic malignancies. Clofarabine is a next generation nucleoside analog which is under clinical investigation. The bone marrow toxicity, tumor cell cytotoxicity and human tumor xenograft activity of fludarabine, cladribine and ...

Langerhans-cell histiocytosis (LCH) results from the accumulation of tissue histiocytes derived from the same progenitor cells as monocytes. Because cladribine is potently toxic to monocytes, we conducted a phase II trial of cladribine. Cladribine was administered to 13 LCH patients at 0.14 mg/kg per day by 2-hour intravenous infusion for 5 consecutive days, every 4 weeks for a maximum of six c...

INTRODUCTION Erdheim-Chester disease (ECD) is a rare, systemic form of non-Langerhans cell histiocytosis of the juvenile xanthogranuloma family with characteristic bilateral symmetrical long bone osteosclerosis, associated with xanthogranulomatous extra skeletal organ involvement. In ECD, central nervous system (CNS) and orbital lesions are frequent, and more than half of ECD pa tients carry th...

Patients with systemic mastocytosis (SM) can suffer from disabling symptoms related to mast cell mediator release or mast cell infiltration, requiring mast cell eradication. In the present absence of any curative therapy, a recent case report describing the efficacy of cladribine showed promising results. In a pilot study, the efficacy of cladribine (0.10-0.13 mg/kg in a 2-hour infusion, days 1...

In this issue of Blood, Rosenberg et al provide a detailed retrospective description of the long-term outcome of young patients with a diagnosis of hairy cell leukemia treated with cladribine.
