Indications and Dosage
Acute lymphoblastic leukaemia
Child: Relapsed or refractory cases (after receiving at least 2 prior regimens): 1-21 yr 52 mg/m2 daily via infusion over 2 hr (>2 hr infusion time in patients weighing <20 kg) for 5 consecutive days. Treatment cycle is repeated every 2-6 wk, following recovery of normal haematopoiesis (i.e. ANC ≥750 cells/mm3) and return to baseline organ function. If significant toxicities occur, the dose may be reduced by 25% of the previous dose. Discontinue if hypotension and signs/symptoms of capillary leak syndrome occur, or if there is substantial increase in serum creatinine and bilirubin levels.
Renal Impairment
Severe: Contraindicated.
 CrCl (mL/min)  Dosage
 30-60  Reduce to 50% of the usual dose.
Hepatic Impairment
Severe: Contraindicated.
IV infusion: Dilute w/ NaCl 0.9% or dextrose 5% to a final concentration between 0.15 to 0.4 mg/mL.
Severe hepatic and renal impairment. Lactation.
Special Precautions
Mild to moderate hepatic and renal impairment. Childn. Pregnancy.
Adverse Reactions
Significant: Bone marrow suppression (e.g. thrombocytopenia, anaemia, lymphopenia, neutropenia), nausea and vomiting, cytokine release syndrome (e.g. tachypnoea, pulmonary oedema, tachycardia), increased bilirubin, transaminases, and creatinine levels; hypotension, haematuria, tumour lysis syndrome or hyperuricaemia, infection.
Nervous: Headache, anxiety, irritability, fatigue, asthenia, lethargy, somnolence, agitation, dizziness, tremor.
CV: Tachycardia, flushing, oedema, HTN, pericardial effusion.
GI: Diarrhoea, abdominal pain, anorexia, oral mucositis, pancreatitis, proctalgia, gingival bleeding.

Others: Fever, chills.
Potentially Fatal: Cerebral, GI, or pulmonary haemorrhage; acute renal failure, Stevens-Johnson syndrome, toxic epidermal necrolysis, enterocolitis (e.g. C. difficile colitis, caecitis, neutropenic colitis), opportunistic infection or sepsis, hepatotoxicity (e.g. hepatitis, hepatic sinusoidal obstruction syndrome), capillary leak syndrome or systemic inflammatory response syndrome (SIRS).
IV/Parenteral: D
Patient Counseling Information
This drug may cause dizziness, fainting, or lightheadedness, if affected, do not drive or operate machinery.
Monitoring Parameters
Obtain CBC and platelet counts daily during treatment, then 1-2 times wkly or as necessary. Monitor hepatic and renal function during the 5 days of admin; cardiac function, BP, coagulation parameters, and resp function during infusion. Assess signs and symptoms of tumour lysis syndrome, infection, hepatic sinusoidal obstruction syndrome, enterocolitis, and cytokine release syndrome.
Symptoms: Diarrhoea, nausea, vomiting, severe bone marrow depression, hyperbilirubinaemia, elevated transaminase levels, maculopapular rash. Management: Supportive treatment.
Drug Interactions
Risk of hepatotoxicity and nephrotoxicity w/ hepato- or nephrotoxic drugs.
Description: Clofarabine is a purine nucleoside antimetabolite that is converted to the active clofarabine 5′-triphosphate which decreases cell replication by competing w/ deoxyadenosine triphosphate for the enzymes ribonucleotide reductase and DNA polymerase. It also disrupts the mitochondrial membrane by releasing cytochrome C and other proapoptotic factors, thereby causing cell death.
Distribution: Volume of distribution: 172 L/m2. Plasma protein binding: Approx 47%, mainly to albumin.
Metabolism: Metabolised intracellularly by deoxycytidine kinase and mono- and diphosphokinases to clofarabine 5’-triphosphate; w/ limited hepatic metabolism (0.2%).
Excretion: Via urine (49-60%, as unchanged drug). Terminal elimination half-life: Approx 5 hr.
