Clofarabine

Introduction

Clofarabine is a chemotherapy medication primarily used to treat specific types of blood cancer, including relapsed or refractory acute lymphoblastic leukemia (ALL) in pediatric patients. It belongs to a class of drugs called purine nucleoside antimetabolites, which interfere with the DNA synthesis in cancer cells, leading to their destruction. Clofarabine is typically administered in hospital settings under the supervision of healthcare professionals due to its strong effects and potential side effects. It plays a crucial role in cancer therapy, especially when other treatments have failed or when rapid cancer progression must be controlled.

Uses of Clofarabine

• Treatment of relapsed or refractory acute lymphoblastic leukemia (ALL)
• Used in pediatric patients aged 1 to 21 years after at least two prior regimens
• May be used in clinical settings for other types of leukemia under specialist guidance

How Clofarabine Works

Clofarabine works by inhibiting DNA synthesis in rapidly dividing cells like cancer cells. It gets incorporated into DNA and RNA, disrupting their function and triggering cell death. This selective action makes it effective in targeting leukemia cells while sparing normal cells to some extent.

Benefits of Clofarabine

• Effective for relapsed or treatment-resistant leukemia
• Targets cancer cells specifically, minimizing damage to normal tissues
• Can be part of combination therapy to increase treatment success
• Available in injectable form for controlled hospital administration

How to Take Clofarabine

Clofarabine is given as an intravenous (IV) infusion over a set period, usually in a hospital setting. Dosage is based on body surface area and medical condition. It's typically administered once daily for five consecutive days in a 2-to-6-week cycle. Always follow the oncologist's instructions strictly.

Type of Dosage Available

• Intravenous (IV) Injection

Side Effects of Clofarabine
