Cabazitaxel is a chemotherapy drug used mainly for the treatment of prostate cancer, especially metastatic castration-resistant prostate cancer (mCRPC). The U.S. Food and Drug Administration approved it in 2010 for prostate cancer that has become resistant to standard hormone therapy and other chemotherapy drugs such as docetaxel. It goes under the brand name Jevtana. Cabazitaxel falls under a drug category that is named taxanes and, therefore affects the division of the cancerous cells. They eventually hinder the progression of the diseases.
Cabazitaxel is most popularly administered for prostate cancer. Even though it was studied upon in clinical studies for different types of cancer, it is primarily prescribed by FDA for prostate cancer.
Cabazitaxel is administered intravenously, usually in a hospital or clinical setting. The treatment is typically given once every three weeks. It is important that this drug is administered under the supervision of a healthcare professional experienced in chemotherapy, as it can cause serious side effects.
The standard dosing regimen for cabazitaxel in metastatic prostate cancer is 25 mg/m², given as an intravenous infusion over a period of one hour. This dose is repeated every three weeks, although adjustments may be made based on individual response, side effects, and the presence of pre-existing medical conditions.
The patients are usually premedicated with corticosteroids like prednisone and antihistamines before initiating the treatment to prevent allergic reactions and infusion-related side effects. Sometimes, growth factor support such as granulocyte-colony stimulating factor is administered to improve white blood cell production and minimize infections as a result of neutropenia caused by chemotherapy.
Cabazitaxel operates by interfering with microtubule dynamics during cell division. Microtubules are one of the most important components in the structure and function of cells, and they play an important role in the segregation of chromosomes during mitosis (cell division). Cabazitaxel stabilizes microtubules by preventing their depolymerization, thereby disrupting the process of mitosis. This disrupts cell division and leads to cell death.
Cancer cells, especially in solid tumors such as prostate cancer, are rapidly dividing. Cabazitaxel selectively kills these rapidly dividing cells and stops them from proliferating. However, the drug does affect normal, dividing cells, and some of the common side effects of chemotherapy include hair loss, nausea, and bone marrow suppression.
Cabazitaxel, like most chemotherapy drugs, has many side effects. Some of the side effects are severe. The common side effects include:
Neutropenia: This is a major concern with cabazitaxel, as it increases the risk of infections. Patients are closely monitored for signs of infection.
Anemia: Fatigue and weakness may result from anemia.
Thrombocytopenia: Low platelet count-thereby increasing the propensity to bleed and bruise.
Nausea/vomiting: Many drugs used in chemotherapy regimens such as cabazitaxel cause these side effects.
Fatigue: A common side effect when receiving this treatment, patient can feel tired and even weak.
Hair loss (alopecia): A common result when a chemotherapy drug destroys or slows the growth of the rapidly dividing cells
Peripheral neuropathy: Involving numbness, pain, or tingling of hands and feet.
Diarrhea: This can be severe and requires careful management, often with supportive medications.
Risk of infection: Because cabazitaxel can cause neutropenia, patients are at a heightened risk of developing serious infections. Monitoring of blood counts is essential before and during treatment.
Hematologic toxicities: Routine blood counts should be performed to monitor white blood cells, red blood cells, and platelets. Dose adjustment or temporary interruption of therapy may be necessary in more severe cases of anemia, neutropenia, and thrombocytopenia.
Pre-existing medical conditions: Cabazitaxel should be used with caution in patients with pre-existing liver or renal disease, as the drug may be metabolized slowly in such patients. The dose may need to be adjusted.
Pregnancy and breastfeeding: Cabazitaxel can cause harm to an unborn child, and it should not be used during pregnancy. It is also unknown whether cabazitaxel passes into breast milk, so breastfeeding is not recommended during treatment.
Allergic reactions: Patients should be monitored for any signs of allergic reactions during and after the infusion.
These interactions highlight the importance of careful management and monitoring when using cabazitaxel alongside other medications.
The typical dosing for cabazitaxel in metastatic castration-resistant prostate cancer is 25 mg/m², intravenously every three weeks. The dose may be decreased as tolerated by the patient, especially if there is a hematologic toxicity (e.g., neutropenia). Dose adjustments are considered if the side effects are severe, particularly when there is significant neutropenia or other symptoms such as diarrhea.
In cases of severe neutropenia or other toxicities, the treatment schedule may be delayed, or the dose may be reduced. Blood cell counts should be closely monitored and the treatment plan adjusted accordingly.
Cabazitaxel is a prescription drug and should only be prescribed by a healthcare provider experienced in the use of chemotherapy. It is usually administered in a hospital or clinic setting because of its potential for serious side effects, and patients can be monitored for complications. The prescribing doctor will assess the patient’s cancer stage, overall health, and any potential contraindications before starting treatment with cabazitaxel.
The regular follow-up visits and blood tests of patients are necessary because cabazitaxel has a potential for hematologic toxicity and other serious side effects. The use of cabazitaxel is indicated in the failure of other treatments, and the treatment plan should be individualized according to the patient’s medical condition and response to therapy.
What is Cabazitaxel?
Cabazitaxel is a chemotherapy medication used to treat metastatic castration-resistant prostate cancer, particularly in patients who have previously been treated with docetaxel.
How does Cabazitaxel work?
Cabazitaxel works by inhibiting cancer cell division. It stabilizes microtubules, preventing their disassembly and thereby disrupting the normal process of cell division, leading to cancer cell death.
What is the usual dosage for Cabazitaxel?
