CAS#: 4291-63-8

Description: Cladribine is a purine nucleoside antimetabolite analogue. Cladribine triphosphate, a phosphorylated metabolite of cladribine, incorporates into DNA, resulting in single-strand breaks in DNA, depletion of nicotinamide adenine dinucleotide (NAD) and adenosine triphosphate (ATP), and apoptosis. Because this agent is resistant to adenosine deaminase, an enzyme that inactivates some antineoplastic agents, it is selectively toxic to lymphocytes and monocytes which exhibit little deoxynucleotide deaminase activity.

Additional Information

Cladribine (Leustatin) is a drug used to treat hairy cell leukemia (leukemic reticuloendotheliosis) and multiple sclerosis. Its chemical name is 2-chlorodeoxyadenosine (2CDA). As a purine analog, it is a synthetic anti-cancer agent that also suppresses the immune system. Chemically, it mimics the nucleoside adenosine and thus inhibits the enzyme adenosine deaminase, which interferes with the cell's ability to process DNA. It is easily destroyed by normal cells except for blood cells, with the result that it produces relatively few side effects and results in very little non-target cell loss.
 
Cladribine is indicated for the treatment of symptomatic hairy cell leukemia (HCL). It is under investigation for other B cell leukemias and lymphomas, such as mantle cell lymphoma,[2], and for use in the treatment of multiple sclerosis. In January 2010, a large clinical trial involving more than 1000 patients documented significant reduction in relapse rates in multiple sclerosis patients with use of oral cladribine and thus making its use as the first oral medication in multiple sclerosis patients, most likely in year [2011]. According to the Histiocytosis Association of America, cladribine is used to treat histiocytosis. See http://en.wikipedia.org/wiki/Cladribine.
 
DRUG DESCRIPTION

LEUSTATIN Injection is available in single-use vials containing 10 mg (1 mg/mL) of cladribine, a chlorinated purine nucleoside analog. Each milliliter of LEUSTATIN Injection contains 1 mg of the active ingredient and 9 mg (0.15 mEq) of sodium chloride as an inactive ingredient. The solution has a pH range of 5.5 to 8.0. Phosphoric acid and/or dibasic sodium phosphate may have been added to adjust the pH to 6.3±0.3.
