How does this medicine work?

• Cladribine (klad' ri been) is a purine analogue (2-chlorodeoxyadeosine) that is used predominantly in the treatment of hairy cell leukemia.
• Cladribine is a chlorodinated derivative of adenine which is converted intracellularly to the cladribine triphosphate, which is believed to compete with adenine triphosphate in DNA synthesis.
• Cladribine was found to have marked activity against hairy leukemia and was approved for this use in the United States in 1993.
• Cladribine has been used off-label to treat low grade lymphomas and other hematologic malignancies, but its current formal indications are limited to therapy of active hairy cell leukemia.

• Cladribine has not been associated with serum enzyme elevations during therapy or with instances of clinically apparent acute liver injury with jaundice.
• Due to increased risk of infection in the setting of immunosuppression with chemotherapy including cladribine, it is recommended not to administer live attenuated vaccines to patients receiving cladribine injection.
