cabazitaxel(redirected from Jevtana)
Pharmacologic class: Taxane
Therapeutic class: Antineoplastic
Pregnancy risk category D
FDA Box Warning
• Neutropenic deaths have been reported. Obtain frequent blood counts to monitor for neutropenia. Don't give drug if neutrophil count is 1,500 cells/mm3 or less.
• Severe hypersensitivity can occur and may include generalized rash, erythema, hypotension, and bronchospasm. Discontinue drug immediately if severe reactions occur and administer appropriate therapy.
• Drug is contraindicated in patients with history of severe hypersensitivity reactions to cabazitaxel or to drugs formulated with polysorbate 80.
As a microtubule inhibitor, cabazitaxel binds to tubulin and promotes its assembly into microtubules while simultaneously inhibiting disassembly. This leads to the stabilization of microtubules, which results in the inhibition of mitotic and interphase cellular functions.
Injection: 60 mg/1.5 ml in single-use vial
Indications and dosages
➣ Metastatic hormone-refractory prostate cancer previously treated with a docetaxel-containing treatment regimen
Adults: 25 mg/m2 I.V. by 1-hour infusion q 3 weeks in combination with prednisone 10 mg P.O. daily throughout treatment
• Grade 3 or greater neutropenia for longer than 1 week despite appropriate treatment, including granulocytecolony stimulating factor (G-CSF)
• Febrile neutropenia
• Grade 3 or greater diarrhea or persisting diarrhea despite appropriate treatment
• Hypersensitivity to drug or to other drugs formulated with polysorbate 80
• Patients with neutrophil counts of 1,500 cells/mm3 or less
Use cautiously in:
• hepatic impairment with total bilirubin at or above the upper limit of normal (ULN), or AST or ALT levels 1.5 × ULN or greater (avoid use)
• severe renal impairment (creatinine clearance less than 30 mL/minute) and end-stage renal disease
• GI symptoms
• infusion reactions
• concurrent use of strong CYP3A inducers or inhibitors (avoid use)
• elderly patients
• pregnant or breastfeeding patients
• children (safety and efficacy not established).
• Follow facility policy for handling, preparing, and administering carcinogenic, mutagenic, and teratogenic drugs.
☞ Don't administer by I.V. push or bolus.
• Premedicate patient at least 30 minutes before each dose with the following I.V. drugs to reduce risk or severity of hypersensitivity: Antihistamine (dexchlorpheniramine 5 mg, or diphenhydramine 25 mg, or equivalent antihistamine), corticosteroid (dexamethasone 8 mg or equivalent steroid), H2 antagonist (ranitidine 50 mg or equivalent H2 antagonist).
• Give oral or I.V. antiemetic prophylaxis as needed.
• Don't use PVC infusion containers or polyurethane infusion sets for preparation or administration of drug.
• Be aware that drug requires two dilutions before administering.
• To reconstitute, use entire contents of accompanying diluent to achieve a concentration of 10 mg/ml. Withdraw only required amount of first dilution to prepare final infusion solution before administering. When transferring diluent, direct needle onto inside wall of vial and inject slowly to limit foaming. Remove syringe and needle and gently mix initial diluted solution by repeated inversions for at least 45 seconds to ensure full mixing of drug and diluent. Don't shake. Let solution stand for a few minutes to allow foam to dissipate; check that solution is homogeneous and contains no visible particulate matter.
• The second dilution should be done immediately (within 30 minutes) to obtain final infusion. Withdraw recommended dose from vial containing 10 mg/ml using calibrated syringe and further dilute into sterile 250-ml PVC-free container of either normal saline solution or 5% dextrose solution for infusion. If dose greater than 65 mg is required, use larger volume of infusion vehicle so that a concentration of 0.26 mg/ml isn't exceeded. Concentration of final infusion solution should be between 0.10 and 0.26 mg/ml. Remove syringe and thoroughly mix final infusion solution by gently inverting bag or bottle. Final infusion solution in either normal saline solution or 5% dextrose solution should be used within 8 hours if kept at ambient temperature (including the 1-hour infusion) or within a total of 24 hours if refrigerated (including the 1-hour infusion).
• Inspect visually for particulate matter, crystals, and discoloration before administering. Discard unused portion.
• Discard first diluted solution or second (final) infusion solution if either isn't clear or appears to have precipitation.
• As final infusion solution is supersaturated, it may crystallize over time. If this occurs, don't use solution; discard it.
• Don't mix with other drugs.
• Use an in-line filter of 0.22-micrometer nominal pore size for administration.
☞ Reduce dosage as prescribed for Grade 3 or greater neutropenia lasting longer than 1 week despite appropriate treatment (including G-CSF), for febrile neutropenia, or for Grade 3 or greater diarrhea or persisting diarrhea despite appropriate treatment. Discontinue drug if patient continues to experience any of these reactions at prescribed lower dosage.
• Consider G-CSF and secondary prophylaxis in all patients considered to be at increased risk for neutropenia complications.
☞ Immediately discontinue infusion if severe hypersensitivity reactions occur and initiate appropriate therapy. Be aware that patients with a history of severe hypersensitivity reactions shouldn't be rechallenged with this drug.

• Monitor CBC with differential and renal and hepatic function tests closely.
• Be aware that the incidence of Grade 3 to 4 hematologic adverse reactions, particularly neutropenia and febrile neutropenia, is higher in patients age 65 or older compared to younger patients.
☞ Be aware that cabazitaxel is extensively metabolized in the liver and hepatic impairment is likely to increase cabazitaxel concentration, with risk of severe and life-threatening complications in patients receiving other drugs belonging to same class.
☞ Continue to closely monitor patents for hypersensitivity reactions, especially during first and second infusions. Hypersensitivity reactions may occur within a few minutes after initiation of infusion; therefore, have facilities and equipment available for treatment of hypotension and bronchospasm. If severe hypersensitivity occurs that includes generalized rash, erythema, hypotension, and bronchospasm, immediately discontinue infusion and initiate appropriate therapy.
• Watch for dehydration if patient has nausea, vomiting, or severe diarrhea; be aware that intensive measures may be required for severe diarrhea and electrolyte imbalance. Initite appropriate measures, including rehydration and antidiarrheal or antiemetic medications, as needed. Delay or reduce dosage as necessary if patient has diarrhea at or above Grade 3.
☞ Be aware that renal failure may occur in association with sepsis, dehydration, or obstructive uropathy. Immediately take appropriate measures to identify causes of renal failure and treat aggressively.
• Explain the importance of taking oral prednisone as prescribed.
• Explain the importance of routine blood cell counts and instruct patient to monitor temperature frequently.
☞ Instruct patient to immediately contact prescriber if signs and symptoms of hypersensitivity reactions occur, including rash or itching, skin redness, dizziness or faintness, chest or throat tightness, facial swelling, or breathing problems.
☞ Instruct patient to immediately contact prescriber if urinary tract problems, irregular heartbeat, significant vomiting or diarrhea, decreased urinary output, or blood in urine occurs.
• Advise patient to report numbness or tingling of the hands or feet or muscle problems.
• Advise patient to contact prescriber if a fever or other evidence of potential infection, such as cough or pain on urination, develops.
• Instruct patient to tell prescriber all drugs he's taking, because some drugs have potential for serious drug interactions and shouldn't be taken with cabazitaxel.
• Advise patient not to use St. John's wort without consulting prescriber.
• Advise female patient of childbearing age to avoid becoming pregnant while receiving this drug.
• Advise breastfeeding patient that she should decide whether to discontinue breastfeeding or discontinue drug, taking into account importance of drug for her treatment.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, and herbs mentioned above.

- Assess for hypersensitivity reactions (generalized rash/erythema, hypotension, bronchospasm, swelling of face). May occur within minutes following initiation of infusion. If severe reactions occur, discontinue infusion immediately and provide supportive therapy.
- Assess for nausea, vomiting, and severe diarrhea; may result in death due to electrolyte imbalance. Premedication is recommended. Treat with rehydration, anti-diarrheal, or antiemetic therapy as needed. If Grade ≥3 diarrhea or persisting diarrhea occurs despite appropriate medication, fluid and electrolyte replacement, delay treatment until improvement or resolution, then reduce dose to 20 mg/mL.
- Lab Test Considerations: Monitor CBC weekly during cycle 1 and before each treatment cycle thereafter. Do not administer if neutrophils ≤1500/mm3. If prolonged grade 3 neutropenia (>1 wk) despite appropriate medication including filgrastim, delay treatment until neutrophil count is >1500 mm3, then reduce dose to 20 mg/m2. Use filgrastim for secondary prophylaxis.
- If febrile neutropenia occurs, delay therapy until improvement or resolution and neutrophil count is >1500/mm3, then reduce dose to 20 mg/m2. Use filgrastim for secondary prophylaxis.
- Discontinue cabazitaxel if prolonged Grade 3 neutropenia, febrile neutropenia, or Grade 3 diarrhea occur at the 20 mg/m2 dose.
- May cause hematuria.
- May cause Grade 3–4 ↑ AST, ↑ ALT, and ↑ bilirubin.
