Cladribine: Drug information

Cladribine: Drug information
(For additional information see "Cladribine: Patient drug information" and see "Cladribine: Pediatric drug information")

For abbreviations, symbols, and age group definitions used in Lexicomp (show table)
ALERT: US Boxed Warning
Experienced physician (injection only):

Cladribine should be administered under the supervision of a qualified health care provider experienced in the use of antineoplastic therapy.

Bone marrow suppression (injection only):

Suppression of bone marrow function should be anticipated. This is usually reversible and appears to be dose dependent.

Malignancy (oral tablet only):

Treatment with cladribine oral tablets may increase the risk of malignancy. Cladribine oral tablets are contraindicated in patients with current malignancy. In patients with prior malignancy or with increased risk of malignancy, evaluate the benefits and risks of the use of cladribine oral tablets on an individual patient basis. Follow standard cancer screening guidelines in patients treated with cladribine oral tablets.

Neurotoxicity (injection only):

Serious neurological toxicity (including irreversible paraparesis and quadriparesis) has been reported in patients who received cladribine by continuous infusion at high doses (4 to 9 times the recommended dose for hairy cell leukemia). Neurologic toxicity appears to demonstrate a dose relationship; however, severe neurological toxicity has been reported rarely following treatment with standard cladribine dosing regimens.

Renal toxicity (injection only):

Acute nephrotoxicity has been observed with high doses of cladribine (4 to 9 times the recommended dose for hairy cell leukemia), especially when given concomitantly with other nephrotoxic agents/therapies.

Risk of teratogenicity (oral tablet only):

Cladribine oral tablets are contraindicated for use in pregnant women and in women and men of reproductive potential who do not plan to use effective contraception because of the potential for fetal harm. Malformations and embryolethality occurred in animals. Exclude pregnancy before the start of treatment with cladribine oral tablets in females of reproductive potential. Advise females and males of reproductive potential to use effective contraception during cladribine oral tablets dosing and for 6 months after the last dose in each treatment course. Stop cladribine oral tablets if the patient becomes pregnant.

Multiple sclerosis, relapsing

Multiple sclerosis, relapsing:

Note: Lymphocytes must be within normal limits before initiating first treatment course and ≥800 cells/mm3 before initiating the second treatment course. If needed, the second treatment course can be delayed up to 6 months to allow lymphocytes to recover to ≥800 cells/mm3. If lymphocytes <800 cells/mm3 after 6-month delay, do not continue cladribine. Screen for HIV, tuberculosis, and hepatitis B and C status prior to each treatment course. For patients who screen positive for latent infections, consult infectious disease or other appropriate specialists (eg, liver specialists) regarding treatment options before initiating therapy (Ref). Initiating oral cladribine during concomitant treatment with immunosuppressive or myelosuppressive therapies is not recommended.

Oral: 3.5 mg/kg over 2-year treatment course, administered as 1.75 mg/kg in each year. Divide the 1.75 mg/kg dose over 2 cycles, each cycle lasting 4 to 5 consecutive days; do not administer more than 20 mg/day. In the first-year treatment course, initiate the first cycle at any time; administer the second cycle 23 to 27 days after the last dose of the first cycle. In the second-year treatment course, initiate the first cycle ≥43 weeks after the last dose of the first year's second cycle. Administer the second cycle 23 to 27 days after the last dose of the second year's first cycle. Following 2 years of treatment, do not administer oral cladribine during the next 2 years. Refer to manufacturer's labeling for additional dosing details, including dosing tables.

Oral tablet [Canadian product]: Additional contraindications (not in US labeling): Increased risk of opportunistic infections (including those immunocompromised due to therapy [immunosuppressive or immunomodulating, antineoplastic or myelosuppressive therapies; total lymphoid irradiation; bone marrow transplantation] or disease [immunodeficiency syndrome]); history of progressive multifocal leukoencephalopathy; moderate or severe renal impairment (CrCL <60 mL/minute).

Warnings/Precautions

Concerns related to adverse effects:

• Bone marrow suppression: Dose-dependent myelosuppression (neutropenia, anemia, and thrombocytopenia) is common with cladribine injection and generally reversible. Lymphopenia has also been reported in patients receiving oral tablets for multiple sclerosis (MS). Use with caution in patients with preexisting hematologic or immunologic abnormalities and patients receiving other drugs that affect the hematologic profile concurrently or prior to treatment with cladribine.

• Cardiotoxicity: Cardiotoxicity, including life-threatening acute cardiac failure with myocarditis, has been reported.

• Fever: Treatment is associated with fever (≥100°F), with or without neutropenia, and is observed more commonly in the first month of treatment.

• Graft-versus-host disease: Graft-versus-host disease (GVHD) has been reported rarely in cladribine treated patients following transfusions of nonirradiated blood. Consult with a hematologist; irradiation of cellular blood components prior to transfusion is recommended.

• Hepatotoxicity: Serious liver injury or liver injury leading to treatment discontinuation has been reported within a few weeks to several months after initiation of cladribine.

• Hypersensitivity: Hypersensitivity reactions have occurred.

• Infection: Serious and potentially fatal infections (bacterial, viral, and fungal) have been reported. Due to neutropenia and T-cell depletion, risk versus benefit of treatment should be evaluated in patients with active infections. If active infection is present, manage appropriately prior to administering cladribine (Grever 2017). For the treatment of MS, screen for HIV, tuberculosis, and hepatitis B and C status prior to each treatment course. For patients who screen positive for latent infections, consult infectious disease or other specialists (eg, liver specialists) regarding treatment options before initiating therapy (AAN [Farez 2019]). Initiating oral cladribine during concomitant treatment with immunosuppressive or myelosuppressive therapies is not recommended.

• Malignancy: Treatment with cladribine oral tablets may increase the risk of malignancy. After the completion of 2 courses of treatment, do not administer cladribine oral tablets for 2 years. Cladribine oral tablets are contraindicated in patients with current malignancy. In patients with prior malignancy or with increased risk of malignancy, evaluate the benefits versus risks of cladribine oral tablets based on individual patient factors. Follow standard cancer screening guidelines in patients treated with cladribine oral tablets.

• Neurotoxicity: Serious, dose-related neurologic toxicity (including irreversible paraparesis and quadriparesis) has been reported with continuous IV infusions of higher doses (4 to 9 times the approved dose); may also occur at approved doses (rare). Neurotoxicity may be delayed and may present as progressive, irreversible motor weakness of the upper and/or lower extremities; diagnostics with electromyography and nerve conduction studies were consistent with demyelinating disease. Neurotoxicity after high-dose administration was first noted 35 to 84 days after therapy initiation.

• Progressive multifocal leukoencephalopathy: Cases of progressive multifocal leukoencephalopathy (PML) due to the John Cunningham (JC) virus have been reported in patients receiving parenteral cladribine for oncologic indications. Symptoms progress over days to weeks and may include progressive weakness on one side of the body or clumsiness of limbs, vision disturbances, and mental status changes. MRI findings may be apparent before patients are symptomatic. Monitoring with brain MRI for signs that may be consistent with PML may be beneficial and allow for an early diagnosis of PML.

• Renal toxicity: Acute nephrotoxicity (eg, acidosis, anuria, increased serum creatinine), possibly requiring dialysis, has been reported with high doses (4 to 9 times the approved dose), particularly when administered with other nephrotoxic agents. Per the manufacturer, nephrotoxicity has not occurred when used at the dose approved for hairy cell leukemia.

• Tumor lysis syndrome: With high tumor burden, tumor lysis syndrome and subsequent hyperuricemia may occur (rare).

Dosage form specific issues:

• Benzyl alcohol and derivatives: Injection: Weekly (7-day) infusion preparation recommends further dilution with bacteriostatic normal saline which contains benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol with caution in neonates. See manufacturer's labeling.

Other warnings/precautions:

• Vaccines: When used in the oncology setting, administration of live-attenuated or live vaccines is not recommended during treatment with cladribine (may increase the risk of infection due to immunosuppression). When using for the treatment of MS, complete necessary immunizations at least 4 to 6 weeks prior to initiating cladribine. Avoid live-attenuated vaccines in patients who currently receive or have recently discontinued cladribine; consider using live-attenuated vaccines only if risk of infection is high and killed vaccines are unavailable (AAN [Farez 2019]). Provide varicella zoster virus (VZV) vaccination prior to initiation of therapy in VZV antibody–negative patients. In antibody-positive patients, vaccination with zoster vaccine (recombinant) is recommended any time prior to or during the course of treatment; may also administer if lymphocyte counts are ≤500 cells/mm3 .

Reproductive Considerations

Evaluate pregnancy status prior to use; exclude pregnancy prior to each treatment course in patients who could become pregnant.

Patients who could become pregnant should use effective contraception during therapy and for 6 months after the last dose of cladribine, regardless of the route of administration/indication for treatment. Patients with partners who could become pregnant should also use effective contraception during therapy and for 6 months after the last cladribine dose. Use of oral cladribine is contraindicated in patients of reproductive potential who do not plan to use effective contraception during therapy and for 6 months after the last dose.

In general, disease-modifying therapies for multiple sclerosis are stopped prior to a planned pregnancy except in patients at high risk of multiple sclerosis activity (AAN [Rae-Grant 2018]). Consider use of agents other than cladribine for patients at high risk of disease reactivation who are planning a pregnancy. Delaying pregnancy is recommended for patients with persistent high disease activity; when disease-modifying therapy is needed in these patients, other agents are preferred (ECTRIMS/EAN [Montalban 2018]).

Pregnancy Considerations

Based on the mechanism of action and data from animal reproduction studies, in utero exposure to cladribine is expected to cause fetal harm. Discontinue cladribine if pregnancy occurs during treatment; use of oral cladribine during pregnancy is contraindicated.

Outcome data related to the use of cladribine for the treatment of hairy cell leukemia (Daver 2013) or multiple sclerosis (Dost-Kovalsky 2023; Giovannoni 2020) during pregnancy are limited.

In general, disease-modifying therapies for multiple sclerosis are not initiated during pregnancy, except in patients at high risk of multiple sclerosis activity (AAN [Rae-Grant 2018]).

Data collection to monitor pregnancy and infant outcomes following exposure to cladribine for the treatment of patients with multiple sclerosis is ongoing. Health care providers are encouraged to enroll patients exposed to cladribine during pregnancy or within 6 months prior to pregnancy in the EMD Serono’s Adverse Event reporting line (800-283-8088 ext. 5563); patients may also enroll themselves.

A long-term observational research study is collecting information about the diagnosis and treatment of cancer during pregnancy. For additional information about the pregnancy and cancer registry or to become a participant, contact Cooper Health (877-635-4499).

Breastfeeding Considerations

Cladribine is present in breast milk.

Data related to the presence of cladribine in breast milk are available from a patient treated for relapsing-remitting multiple sclerosis after experiencing a relapse. Four months postpartum she was treated with cladribine 20 mg once daily for 4 days, then 10 mg on day 5. Five weeks later she was treated with cladribine 20 mg once daily for 3 days, then 10 mg daily for 2 days. Breast milk was sampled over 24 hours during the second treatment. One hour following a 20 mg dose on day 3, breast milk concentrations of cladribine were 281.2 ng/mL and then decreased rapidly. At 48, 72, and 96 hours after the last dose, cladribine breast milk concentrations were below the limit of quantification (1.5 ng/mL). Using the average breast milk concentration, authors of the study calculated the estimated daily infant dose via breast milk to be 0.0066 mg/kg/day, providing a relative infant dose (RID) of 3.06% compared to a weight-adjusted maternal dose of cladribine 20 mg. Breastfeeding was suspended during treatment (Datta 2021). In general, breastfeeding is considered acceptable when the RID of a medication is <10% (Anderson 2016; Ito 2000).

Use of the oral tablet is contraindicated in lactating patients during treatment and for 10 days after the last cladribine dose. Due to the potential for serious adverse reactions in the breastfed infant, manufacturers of cladribine injection recommend discontinuing cladribine or discontinuing breastfeeding, considering the importance of treatment to the mother. Some sources recommended withholding breastfeeding for at least 48 hours after the last cladribine dose, longer in patients with impaired renal function (Almas 2016).

Monitoring Parameters

IV: CBC with differential (at baseline, during, and after treatment; particularly during the first 4 to 8 weeks post-treatment), renal and hepatic function; bone marrow biopsy (after CBC has normalized, to confirm treatment response). Monitor for fever; monitor for signs/symptoms of neurotoxicity, infection, hepatotoxicity, progressive multifocal leukoencephalopathy (PML), and tumor lysis syndrome. Assess risk for opportunistic infections (eg, pneumocystis jirovecii pneumonia, herpes virus infection).

The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.

Oral tablet: CBC including lymphocyte count (before each treatment course, 2 and 6 months after the start of each yearly course [if 2-month lymphocyte <200 cells/mm3, monitor monthly until month 6], and periodically during and after treatment); liver function tests (serum aminotransferase, alkaline phosphatase, and total bilirubin levels) (prior to each treatment course and as clinically appropriate). Evaluate HIV, tuberculosis, hepatitis B (HBV) and hepatitis C (HCV) status (prior to each treatment course); evaluate varicella zoster virus (VZV) antibody status (prior to treatment initiation). Verify pregnancy status (prior to each treatment course in patients who could become pregnant). MRI (at baseline [within 3 months] prior to first treatment course). Monitor for signs or symptoms of progressive multifocal leukoencephalopathy (if suspected, perform a diagnostic evaluation and obtain brain MRI scan); follow standard guidelines for cancer screening; monitor for signs or symptoms of acute infection.

Mechanism of Action

Cladribine is a purine nucleoside analogue; it is a prodrug which is activated by phosphorylation and converted into the active moiety, Cd-ATP. This active form incorporates into DNA to result in the breakage of DNA strand and shutdown of DNA synthesis and repair. This also results in a depletion of nicotinamide adenine dinucleotide and adenosine triphosphate (ATP). Cladribine is cell-cycle nonspecific. The mechanism of cladribine in treating multiple sclerosis (MS) is unknown, but may involve cytotoxic effects on B and T lymphocytes that result from the shutdown of DNA synthesis, leading to a depletion of lymphocytes.
